Overview
We are a biopharmaceutical company involved in the development of an injectable collagenase for multiple indications. We have a development and license agreement with Auxilium Pharmaceuticals, Inc. (“Auxilium”) for injectable collagenase (which Auxilium has named XIAFLEX
®
(collagenase clostridium histolyticum)) for clinical indications in Dupuytren’s contracture, Peyronie’s disease, frozen shoulder (
adhesive capsulitis
) and cellulite (
edematous fibrosclerotic panniculopathy
). Auxilium has an option to acquire additional indications that we may pursue, including human and canine lipoma. Auxilium is currently selling XIAFLEX in the U.S. for the treatment of Dupuytren’s contracture. Auxilium has an agreement with Pfizer, Inc. (“Pfizer”) pursuant to which Pfizer has marketing rights for XIAPEX
®
(the EU trade name for collagenase clostridium histolyticum) for Dupuytren’s contracture and Peyronie’s disease in Europe and certain Eurasian countries until April 24, 2013. In addition, Auxilium has an agreement with Asahi Kasei Pharma Corporation (“Asahi”) pursuant to which Asahi has the right to commercialize XIAFLEX for the treatment of Dupuytren’s contracture and Peyronie’s disease in Japan. Auxilium also has an agreement with Actelion Pharmaceuticals Ltd. (“Actelion”) pursuant to which Actelion has the right to commercialize XIAFLEX for the treatment of Dupuytren’s contracture and Peyronie’s disease in Canada, Australia, Brazil and Mexico. Auxilium has been granted a Notice of Compliance (approval) by Health Canada for XIAFLEX for the treatment of Dupuytren’s contracture in adults with a palpable cord in Canada.
Operational Highlights
Peyronie’s Disease
. In December 2012, the U.S. Food and Drug Administration (“FDA”) accepted for filing Auxilium’s supplemental Biologics License Application (“sBLA”) for XIAFLEX for the potential treatment of Peyronie's disease. As a result, we recognized a $1
.0
million milestone payment from Auxilium. The filing was granted standard review status and, under the Prescription Drug User Fee Act (“PDUFA”), the FDA is expected to take action on the application by September 6, 2013. Auxilium has reported that the FDA is not planning on holding an Advisory Committee meeting for the use of XIAFLEX in the treatment of Peyronie’s disease, but cautions that it can offer no assurance that the FDA will not require an Advisory Committee meeting in the future. The sBLA was based on results from Auxilium’s phase III clinical program that assessed XIAFLEX for the potential treatment of Peyronie’s disease and is known as IMPRESS (The Investigation for Maximal Peyronie’s Reduction Efficacy and Safety Studies)
.
The Journal of Urology has electronically published on its website the uncorrected proof of Auxilium’s IMPRESS clinical program. In announcing this publication, Auxilium’s Chief Executive Officer and President, Adrian Adams, noted that “We believe that XIAFLEX, if approved for the treatment of Peyronie’s Disease, has the clinical profile to become a potential breakthrough treatment . . . With its current indication in Dupuytren’s contracture, positive clinical results in Peyronie’s disease, and development ongoing in Frozen Shoulder syndrome and Cellulite, [XIAFLEX] represents a pipeline in a product with potential applications in multiple therapeutic areas that currently have limited treatment options.”
Cellulite
. Auxilium expanded the field of its license for injectable collagenase to include the potential treatment of adult patients with cellulite by exercising, in January 2013, its exclusive option under our development and license agreement. As a result of this exercise, we received a license fee payment of $500,000 from Auxilium. We paid a portion of this payment to the Research Foundation of the State University of New York at Stony Brook pursuant to the terms of our in-licensing agreement described below in the “In-Licensing and Royalty Agreements” section under the heading “Cellulite”. Auxilium’s exercise of this option follows its fourth quarter 2012 announcement of top-line 30-day data from the phase Ib study of XIAFLEX for the potential treatment of adult patients with cellulite, in which all doses of XIAFLEX were generally well-tolerated. These data support the progression into a phase IIa clinical trial in cellulite, which Auxilium plans to initiate in the second half of 2013.
Frozen Shoulder
. Auxilium completed enrollment in its frozen shoulder phase IIa clinical trial in the third quarter of 2012. Auxilium expects top-line data from this XIAFLEX study in the first quarter of 2013
.
Auxilium anticipates initiating a phase II clinical trial of frozen shoulder in the second half of 2013.

Auxilium and Actelion announced in the beginning of the third quarter of 2012 that Auxilium was granted a Notice of Compliance (approval) by Health Canada for XIAFLEX for the treatment of Dupuytren’s contracture in adults with a palpable cord in Canada. Under the terms of the collaboration agreement between Actelion and Auxilium, Actelion is to receive exclusive rights to commercialize XIAFLEX for the treatment of Dupuytren’s contracture and Peyronie's disease in Canada, Australia, Brazil and Mexico upon receipt of the respective regulatory approvals. Pursuant to this agreement, Auxilium intends to transfer regulatory sponsorship of the dossier to Actelion
,
and Actelion will be primarily responsible for the applicable regulatory and commercialization activities for XIAFLEX in Canada and, upon approval, in the remainder of these countries. Actelion expects to make XIAFLEX available to patients in Canada in the first half of 2013
.

Also in the third quarter, Auxilium announced positive top-line data from its open-label phase IIIb trial evaluating XIAFLEX for the treatment of adult Dupuytren's contracture patients with multiple palpable cords. Auxilium enrolled 60 patients at eight sites throughout the U.S. and Australia. Following the announcement of these data, Auxilium began a larger study with XIAFLEX for the concurrent treatment of multiple palpable cords that, if successful, may allow Auxilium to seek FDA approval of the expansion of the Dupuytren's label. Auxilium expects top-line results in the first half of 2014. Based on research by SDI Health, LLC estimating that 35 to 40% of annual Dupuytren's surgeries in the U.S. are performed to treat two or more cords concurrently, Auxilium is conducting these studies to seek a multicord indication for XIAFLEX from the FDA. It is hoped that more surgeons will perform the XIAFLEX injection in these cases, rather than surgery, if the FDA approves the label expansion.

Auxilium completed enrollment in its Dupuytren’s contracture retreatment phase IV clinical trials in the third quarter of 2012 and expects top-line results from these trials in the fourth quarter of 2013.
|
Lipoma
. We initiated two clinical trials in the second quarter of 2012. One is a 14 patient, single center dose escalation phase II clinical trial of XIAFLEX for the treatment of human lipoma. The other is a placebo controlled randomized phase II trial, Chien-804, to evaluate the efficacy of XIAFLEX for canines with benign subcutaneous lipomas.
Research and Development of Injectable Collagenase for Multiple Indications
On June 3, 2004, we entered into, and later amended, a development and license agreement with Auxilium pursuant to which we granted to Auxilium an exclusive worldwide license to develop, market and sell products containing our injectable collagenase for the treatment of Dupuytren’s contracture, Peyronie's disease, frozen shoulder and cellulite, as well as an exclusive option to develop and license the technology for use in additional indications other than dermal formulations labeled for topical administration. We have amended and restated that agreement twice, once on December 11, 2008 in connection with the Development, Commercialization and Supply Agreement, dated December 17, 2008 between an Auxilium subsidiary and Pfizer, and more recently on August 31, 2011 (the “Auxilium Agreement”). The Auxilium Agreement and other licensing agreements are discussed more fully throughout this Item 1, in particular under the section titled “Licensing and Marketing Agreements.”
Background on Collagenase
Collagenase is the only protease that can hydrolyze the triple helical region of collagen under physiological conditions. The specific substrate collagen comprises approximately one-third of the total protein in mammalian organisms, and it is the main constituent of skin, tendon, and cartilage, as well as the organic component of teeth and bone. The body relies on endogenous collagenase production to remove dead tissue, and collagenase production is an essential biological mechanism, which regulates matrix remodeling and the normal turnover of tissue. The
Clostridial
collagenase produced by us has a broad specificity towards all types of collagen and is acknowledged as much more efficient than mammalian collagenases.
Clostridial
collagenase cleaves the collagen molecule at multiple sites along the triple helix whereas the mammalian collagenase is only able to cleave the molecule at a single site along the triple helix.
Collagenase is widely used for cell dispersion for tissue disassociation and cell culture because it does not damage the cell membrane. Since the main component of scar tissue is collagen, collagenase has been used in a variety of clinical investigations to remove scar tissue without surgery. Histological and biochemical studies have shown that the tissue responsible for the deformities associated with Dupuytren’s contracture and Peyronie’s disease is primarily composed of collagen. Surgical removal of scar tissue has the potential to result in complications including increased scar formation. Due to the highly specific nature of the
Clostridial
collagenase enzyme, we consider its use to be more desirable for the removal of unwanted tissue than the application of general proteolytic enzymes. Treatment with injectable collagenase for removal of excessive scar tissue represents a first in class non-invasive approach to this unmet medical need. The lead indications involving our injectable collagenase are Dupuytren’s contracture, Peyronie’s disease, frozen shoulder, cellulite, human lipoma and canine lipoma. New clinical indications involving the therapeutic application of
Clostridial
collagenase to supplement the body’s own natural enzymes are continuously being proposed to us by specialists in the medical community.
Collagenase for Treatment of Dupuytren’s Contracture
Dupuytren’s contracture is a deforming condition of the hand in which one or more fingers contract toward the palm, often resulting in physical disability. The onset of Dupuytren’s contracture is characterized by the formation of nodules in the palm that are composed primarily of collagen. As the disease progresses, the collagen nodules begin to form a cord causing the patient’s finger(s) to contract, making it impossible to open the hand fully. Patients often complain about the inability to wash their hands, wear gloves, or grasp some objects. Dupuytren’s contracture has a genetic basis and is most prevalent in individuals of northern European ancestry. Well-known individuals with Dupuytren’s contracture include President Ronald Reagan, President George Bush, and Prime Minister Margaret Thatcher.
XIAFLEX is the only drug approved by the FDA for the treatment of Dupuytren’s contracture. Prior to FDA approval of XIAFLEX, the only proven treatment for Dupuytren’s contracture was surgery. Recurrence rates after surgery can be as high as 30% the first two years after surgery and 55% within ten years of surgery. According to Auxilium in its Annual Report on Form 10-K filed with the Securities and Exchange Commission (“SEC”) on February 26, 2013 (the “Auxilium 10-K”), “[s]ince its launch in the first quarter of 2010, XIAFLEX use has grown, comprising 29% of Dupuytren's procedures in the third quarter of 2012, while, over that same time period, the percentage of Dupuytren's procedures performed by surgery and needle aponeurotomy has decreased”.
Commercialization of XIAFLEX for Dupuytren’s Contracture in the United States
Auxilium has been marketing XIAFLEX for the treatment of adult Dupuytren's contracture patients with a palpable cord since it became available by prescription in March 2010, following Auxilium’s receipt of marketing approval from the FDA. The prescribing information for XIAFLEX made available by Auxilium lists “tendon rupture or other serious injury to the injected extremity,” as well as “pulley rupture, ligament injury, complex regional pain syndrome, and sensory abnormality of the hand,” as reported serious adverse reactions to XIAFLEX. The prescribing information for XIAFLEX also states that the most frequently reported adverse drug reactions in XIAFLEX clinical trials included swelling of the injected hand, contusion, injection site reaction, injection site hemorrhage, and pain in the treated extremity. The prescribing information notes that adverse reaction rates observed in clinical trials of a drug may not reflect those observed in practice because such trials “are conducted under widely varying conditions.” As a condition of its approval of XIAFLEX, the FDA required a risk evaluation and mitigation strategy (“REMS”) program for XIAFLEX, which consists of a communication plan and a medication guide. This REMS program is designed (1) to evaluate and mitigate known and potential risks and serious adverse events; (2) to inform healthcare providers about how to properly inject XIAFLEX and perform finger extension procedures; and (3) to inform patients about the serious risks associated with XIAFLEX.
On September 5, 2012, Auxilium announced a safety update following 30 months of post-approval use in the U.S. of XIAFLEX for the treatment of adult Dupuytren’s contracture patients with a palpable cord. As reported by Auxilium, after approximately 27,000 injections were administered to approximately 21,000 patients in the U.S., there was no clinically meaningful change in the nature of events expected relative to the clinical trial safety profile. Auxilium’s estimates of the number of adverse events are based upon voluntary reporting and reflect all information available to Auxilium from February 2, 2010 thru July 31, 2012 for the use of XIAFLEX in adult patients with Dupuytren’s contracture with a palpable cord in the U.S.
According to Auxilium, research by SDI Health, LLC estimates that 35 to 40% of annual Dupuytren’s surgeries in the U.S. are performed to treat two or more cords concurrently, and Auxilium is conducting studies to seek a multicord indication for XIAFLEX from the FDA. In July 2012, Auxilium announced positive top-line data from the open-label phase IIIb clinical trial designed to assess the safety and efficacy of concurrent administration of two injections of XIAFLEX into the same hand of adult Dupuytren's contracture patients with multiple palpable cords. In this study, 60 patients at eight sites throughout the U.S. and Australia received two concurrent injections of 0.58 mg of XIAFLEX per affected hand and efficacy was based on a single injection per contracted joint. At 30 days, 60% of all joints, 76% of metacarpophalangeal (MP) and 33% proximal interphalangeal joints achieved clinical success (defined as joint correction to 0 to 5 degrees) following this single injection when two 0.58 mg doses of XIAFLEX were administered concurrently into the same hand. Later in the third quarter of 2012, Auxilium initiated a larger study with XIAFLEX for the concurrent treatment of multiple palpable cords that, if successful, may allow Auxilium to seek FDA approval and expansion of the Dupuytren’s label.
Status of Regulatory Approval of XIAFLEX for Dupuytren’s Contracture in Europe
Pfizer has marketing rights for XIAPEX for Dupuytren’s contracture and Peyronie’s disease in Europe and certain Eurasian countries until April 24, 2013 when, by mutual agreement, Auxilium’s collaboration agreement with Pfizer will conclude. After April 24, 2013, rights to commercialize XIAPEX and responsibility for regulatory activities for XIAPEX in these countries will revert to Auxilium. Auxilium has reported that it is currently evaluating strategic options for the continuing commercialization of XIAPEX for the treatment of Dupuytren’s contracture and for gaining approval for XIAPEX for the treatment of Peyronie’s disease in the EU and other specified markets when the rights revert to Auxilium.
Status of Regulatory Approval of XIAFLEX for Dupuytren’s Contracture in Canada
Auxilium and its partner, Actelion, announced on July 9, 2012 that Health Canada granted a Notice of Compliance (approval) for XIAFLEX as a treatment for Dupuytren’s contracture for adult patients with a palpable cord in Canada. As a result of this approval, Auxilium received a $0.5 million regulatory milestone payment from Actelion, of which we received $28,500, or 5.7%.
We are also entitled to 5.7% of all future milestone payments paid to Auxilium by Actelion. Under the terms of the collaboration agreement between Actelion and Auxilium, Actelion received exclusive rights to commercialize XIAFLEX for the treatment of Dupuytren's contracture and Peyronie's disease in Canada, Australia, Brazil and Mexico upon receipt of the respective regulatory approvals. Pursuant to this collaboration agreement, Auxilium intends to transfer regulatory sponsorship of the dossier to Actelion and Actelion will be primarily responsible for the applicable regulatory and commercialization activities for XIAFLEX in Canada and, upon approval, in the remainder of these countries. Actelion expects to make XIAFLEX available to patients in Canada in the first half of 2013.
Collagenase for Treatment of Peyronie’s Disease
Peyronie’s disease is characterized by the presence of a collagen plaque on the shaft of the penis, which can distort an erection and make intercourse difficult or impossible in advanced cases. In some mild cases, the plaque can resolve spontaneously without medical intervention. In severe cases, the penis can be bent at a 90-degree angle during erection. Significant psychological distress has been noted in patients with Peyronie’s disease who are sexually active. Frequent patient complaints include increased pain, painful erections, palpable plaque, penile deformity, and erectile dysfunction. Patients with Peyronie’s disease have been reported to have an increased likelihood of having Dupuytren’s contracture, frozen shoulder, plantar fibromatosis, knuckle pads, hypertension and diabetes. Peyronie’s disease typically affects males in the range of 40-70 years. The cause of Peyronie’s disease is unknown, although some investigators have proposed that it may be due to trauma or an autoimmune component. A number of researchers have suggested that the incidence of Peyronie’s disease has increased due to the use of erectile dysfunction drugs. Although the estimated prevalence of Peyronie’s disease in adult men has been reported to be approximately 5% (See Bella A. Peyronie’s Disease J Sex Med 2007; 4:1527-1538), the disease is thought to be underdiagnosed and undertreated. (See L.A. Levine Peyronie’s Disease: A Guide to Clinical Management. Humana Press: 10-17, 2007). According to Auxilium, based on U.S. historical medical claims data, it is estimated that between 65,000 and 120,000 patients are diagnosed with Peyronie’s disease every year, but only 5,000 to 6,500 Peyronie’s disease patients are treated with injectables or surgery annually.
Currently, there are no FDA approved pharmaceutical products that are labeled as effective for use in Peyronie’s disease. If approved by the FDA, XIAFLEX is expected to be the first and only biologic therapy indicated for the treatment of Peyronie’s disease.
Development Status
As announced by Auxilium on December 27, 2012, the FDA has accepted for filing and granted standard review status to Auxilium’s sBLA for XIAFLEX for the potential treatment of Peyronie's disease. Under PDUFA, the FDA is expected to take action on the application by September 6, 2013. Auxilium has reported that the FDA is not planning on holding an Advisory Committee meeting for the use of XIAFLEX in the treatment of Peyronie’s disease, but cautions that it can offer no assurance that the FDA will not require an Advisory Committee meeting in the future.
Auxilium’s sBLA submission for XIAFLEX as a potential treatment for Peyronie’s disease is based on data from Auxilium’s IMPRESS (The Investigation for Maximal Peyronie's Reduction Efficacy and Safety Studies) phase III clinical program and other controlled and uncontrolled clinical studies, in which over 1,000 Peyronie’s disease patients were enrolled and received over 7,400 injections of XIAFLEX. IMPRESS is described in more detail below. The uncorrected proof of the IMPRESS clinical program has been electronically published on The Journal of Urology’s website, and the manuscript is currently scheduled to appear in print in the July 2013 print version of The Journal of Urology.
Phase III
On June 4, 2012, we announced positive top-line results from the IMPRESS phase III clinical program of XIAFLEX for the treatment of Peyronie's disease, which was conducted by Auxilium. IMPRESS consists of the following four clinical studies:
|
·
|
two identical randomized, double-blind, placebo-controlled phase III studies, which enrolled over 800 patients combined at 64 sites in the U.S. and Australia in less than five months, with a 2:1 ratio of XIAFLEX to placebo;
|
|
·
|
one open label study, which enrolled at least 250 patients, at approximately 30 sites in the U.S., EU and New Zealand; and
|
|
·
|
one pharmacokinetic study, which enrolled approximately 20 patients who were then enrolled into the open label study.
|
XIAFLEX was administered two times a week every six weeks for up to four treatment cycles (2 x 4). Each treatment cycle was followed by a penile modeling procedure. Patients were followed for 52 weeks post-first injection in the double-blind studies and were followed for 36 weeks in the open label and pharmacokinetic trials. The trials’ co-primary endpoints are percent improvement from baseline in penile curvature deformity compared to placebo and the change from baseline (improvement) in the Peyronie’s disease bother domain of the PDQ compared to placebo. The PDQ also has two additional domains as secondary endpoints, which include severity of psychological and physical symptoms of Peyronie’s disease, and penile pain. Safety measurements include adverse event monitoring and clinical labs. Immunogenicity testing was also performed.
As described by Auxilium in the Auxilium 10-K, “In the two phase III double-blind placebo-controlled IMPRESS studies, [XIAFLEX] demonstrated statistically significant improvement in the co-primary endpoints of improvement in penile curvature deformity and improvement in patient-reported bother versus placebo. In IMPRESS I at 52 weeks, the co-primary endpoints met statistical significance with a 37.6% mean reduction in penile curvature deformity for [XIAFLEX] subjects (p=0.0005) and a 3.3 point improvement in the Peyronie's Disease Questionnaire (PDQ) bother domain for [XIAFLEX] subjects (p=0.0451). In IMPRESS II at 52 weeks, the co-primary endpoints met statistical significance with a 30.5% mean improvement in penile curvature deformity for [XIAFLEX] subjects (p=0.0059) and a 2.4 point improvement in the PDQ bother domain for [XIAFLEX] subjects (p=0.0496).” In addition, “[XIAFLEX] was generally well-tolerated. The most common adverse events reported in the double-blind, placebo-controlled IMPRESS phase III trials were hematoma, pain and swelling at the treatment site. These adverse events were comparable to the previous trials: most adverse events were mild or moderate in severity and resolved within 14 days. There were three serious adverse events of corporal rupture (penile fracture) and three serious adverse events of hematomas related to [XIAFLEX] reported in IMPRESS I and II. All three corporal ruptures resolved following intervention and two of three hematomas resolved with intervention, with the third hematoma resolving without intervention. Although >98% of patients developed positive AUX I or II antibodies in the IMPRESS studies, there have been no systemic hypersensitivity events reported in the phase III trials or any of the previous [XIAFLEX] Peyronie’s disease clinical studies to date. Including data from all [XIAFLEX] Peyronie’s disease clinical studies, over 7,500 XIAFLEX injections have been administered to more than 1,050 [Peyronie’s disease] patients.”
Based on data from this IMPRESS phase III clinical program and other controlled and uncontrolled studies, Auxilium submitted its sBLA for XIAFLEX as a potential treatment for Peyronie’s disease, which the FDA has accepted for filing and granted standard review status. Under PDUFA, the FDA is expected to take action on the sBLA by September 6, 2013.
Collagenase For Treatment of Frozen Shoulder (
Adhesive Capsulitis
)
Frozen shoulder is a clinical syndrome of pain and decreased motion in the shoulder joint. It is estimated to affect 20 to 50 million people worldwide with a slightly higher incidence in women. It is estimated that 700,000 patients visit doctors annually in the U.S. in connection with frozen shoulder. It typically occurs between the ages of 40-70. Individuals with insulin dependent diabetes have been reported to have a 36% higher incidence rate and are more likely to have bilateral symptoms. According to the Auxilium 10-K, the most common treatments for frozen shoulder syndrome are extensive physical therapy, corticosteroids and/or arthroscopy, and some drugs are used to manage pain.
We initiated, monitored and supplied requisite study drug for a phase II clinical trial using our injectable collagenase in the treatment of frozen shoulder. Three different doses of injectable collagenase were compared to placebo in this double-blind, randomized trial in 60 patients. Results of this phase II clinical trial were presented at the annual meeting of the American Academy of Orthopaedic Surgeons in March 2006. Based on its review of the final study report from us, Auxilium elected to exercise its option to develop and commercialize this additional indication for collagenase injection in December 2005.
Phase II
Auxilium commenced a phase IIa escalation trial in December 2011 to assess the safety and efficacy of XIAFLEX in the treatment of frozen shoulder syndrome in comparison to an exercise-only control group. This study involved two doses (0.29 mg and 0.58 mg) of XIAFLEX given under ultrasound guidance and involves approximately 50 subjects across 4 cohorts. Up to three injections were given 21 days apart and the subjects are being followed for 90 days. The endpoint will be range of motion parameters for the affected shoulder. Auxilium expects to announce top-line results of this trial in the first quarter of 2013.
In its presentation for its fourth quarter 2012 earnings call, Auxilium lists as a key objective for 2013 the initiation in the second half of 2013 a phase II clinical trial of XIAFLEX for the treatment of Frozen Shoulder syndrome.
Collagenase For Treatment of Cellulite (
Edematous Fibrosclerotic Panniculopathy
)
Edematous fibrosclerotic panniculopathy, commonly known as cellulite, describes a condition, in which lobules of subcutaneous adipose tissue extend into the dermal layer. Cellulite can involve the loss of elasticity or shrinking of collagen cords, called septae, that attach the skin to lower layers of muscle. When fat in cellulite prone areas swells and expands, the septae tether the skin, which causes surface dimpling characteristic of cellulite. These changes can visibly affect the shape of the epidermis and resemble an orange peel-like dimpling of the skin. (See Avram, Cellulite: a review of its physiology and treatment, Journal of Cosmetic Laser Therapy 2004; 6: 181–185). XIAFLEX treatment is intended to target and lyse, or break, those collagen tethers with the goal of releasing the skin dimpling and potentially resulting in smoothing of the skin.
Cellulite has been reported to occur in 85-98% of post-pubertal females and rarely in men, and it is believed to be prevalent in women of all races. (See Avram, Cellulite: a review of its physiology and treatment, Journal of Cosmetic Laser Therapy 2004; 6: 181–185; Khan MH et al. Treatment of cellulite: Part I. Pathophysiology. J Am Acad Dermatol. 2010 Mar;62(3):361-70). As noted in the Auxilium 10-K, “[c]urrent treatments for cellulite include creams, light-based procedures or liposuction. None has been demonstrated to have a significant impact on eliminating cellulite”.
In January 2013, Auxilium exercised its exclusive option under the Auxilium Agreement to expand the field of its license for injectable collagenase to include the potential treatment of adult patients with cellulite. As a result, we received a one-time license fee payment of $500,000, a portion of which we paid to the Research Foundation of the State University of New York at Stony Brook pursuant to the terms of our in-licensing agreement described below in the “In-Licensing and Royalty Agreements” section under the heading “Cellulite”. Auxilium’s exclusive, worldwide license has now been expanded, subject to the terms of the Auxilium Agreement, to include all research, development, use, commercialization, marketing, sales and distribution rights for injectable collagenase for the potential treatment of cellulite. Auxilium plans to initiate a phase II trial for this indication in the second half of 2013.
In December 2012, Auxilium announced top-line 30-day data from its phase Ib, single site, open-label dose escalation study of XIAFLEX for the treatment of cellulite. The study enrolled 99 women between 21 and 60 years of age. Study participants were assigned to one of 11 arms, each of which varied in treatment dose, injection concentration and volume, to receive a single injection of XIAFLEX, divided into 10 aliquots over a pre-defined 8x10cm template around a target dimple. The objectives of the study are to assess the safety and effectiveness of a single injection of XIAFLEX for the treatment of cellulite at 30, 60 and 90 days across multiple dosing arms. Pharmacokinetic evaluations were made as well. Across all dosing arms, 60 patients (63%) who were treated experienced some improvement in the volume of their target cellulite dimple at Day 30. Overall, 17% of patients had a greater than or equal to 30% improvement in their target dimple at Day 30; however, multiple XIAFLEX dosing arms had more than 40 percent of patients experience an improvement greater than or equal to 30% in their target dimple at Day 30. Treatment-related adverse events with XIAFLEX were mostly localized bruising, injection site discomfort and swelling, and all such events resolved without intervention, which are all consistent with XIAFLEX use in other indications.
Additional Clinical Indications For Collagenase
Human Lipoma
Lipomas are benign fatty tumors that occur as bulges under the skin and affect humans and canines. It is estimated that lipomas are the primary diagnosis in 575,000 patients in the U.S. annually. The only proven therapy for lipoma treatment is surgery, which is often not practical for patients with multiple lipomas. Based on observations made during preclinical studies that a collagenase injection decreased the size of fat pads in animals, we initiated, monitored and supplied the requisite study drug for a phase I open label clinical trial for the treatment of human lipomas with a single injection of collagenase. Favorable initial results (10 out of 12 patients had a 50-90% reduction in the size of the lipomas) from this trial for the treatment of human lipomas were presented at a meeting of the American Society of Plastic Surgeons.
We have initiated a 14-patient, single center dose escalation, phase II clinical trial of XIAFLEX for the treatment of human lipoma. The study is a single injection, open-label trial, and XIAFLEX is being administered in four ascending doses (0.058 mg to 0.44 mg). The primary efficacy endpoint will be a change in the visible surface area of the target lipoma, as determined at six months post-injection. We have completed enrollment for this study and expect top-line data in the second half of 2013.
Canine Lipoma
Based on the encouraging results reported in the clinical investigations in human lipoma, we began clinical trials in canine lipoma. Lipomas are found in 2.3% of canines, and there may be as many as 1.7 million canines affected with skin lipomas in the U.S. Lipomas in older canines are very common, and lipomas that restrict motion in older canines are a serious problem. The only proven therapy for this condition is surgical excision of the lipoma, which necessarily involves the use of general anesthesia. It has been estimated that up to 2% of sick canines die as a complication of general anesthesia (See Brodbelt Vet J 2009 Dec; 182 (3): 375-6). We surveyed 77 veterinarians which included participants from the academic field and others that are in private practice. The participants indicated that on average they perform 25 lipoma excision surgeries per year at an average cost of $530 for the surgical procedure. It is conservatively estimated that 47,000 veterinarians are in active practice in the U.S.
Chien-801 and Chien-802 Clinical Trials
Chien-801 was a pilot study conducted for the purpose of evaluating the use of purified collagenase for the non-surgical treatment of lipoma in six canines. The study evaluated the appropriate dosage and frequency of injections necessary to significantly reduce the size of the lipoma. The dose administered ranged from 0.012 to 0.021 mg/ cm2 which was approximately ½ to ¾ of the dose used in previous human clinical trials. Based on this dose escalation study the Company selected the dose for Chien-802.
Chien-802 was designed to evaluate the efficacy of injectable collagenase in canine lipoma in four healthy canines with subcutaneous lipomas. Inclusion criteria required the lipoma to be benign, superficial and easily measureable. All canines had a second lipoma that was untreated and used as a control. At 90 days post injection, in the three evaluable canines, the lipoma size was 0%, 0% or 7% of the original size as measured by a CT scan. By contrast, the untreated lipomas were 129%, 113% and 128% of the original size at day 90. Thus, the treated lipomas showed a 97% reduction in the size of the lipoma and an increase in the size of the untreated controls of 23%.
Chien-803
Based on the positive results from Chien-802, we announced on January 6, 2011 that we had begun enrollment in a randomized, double-blind, placebo-controlled study designed to evaluate the efficacy of purified collagenase for injection for the treatment of canine lipomas. The trial was to enroll 25 canines, each having two or more lipomas. To meet the primary endpoint, an animal would have to have achieved at least a 50% decrease in the drug-treated lipoma volume relative to baseline as measured by CT scan at 3 months post injection. We subsequently discontinued this study and designed a new trial, Chien-804.
Chien-804
We have initiated a placebo controlled randomized study to evaluate the efficacy of XIAFLEX for the treatment of subcutaneous benign lipomas in canines. The study will consist of 32 canines randomized at 1:1 XIAFLEX or placebo. The treatment is a single injection of XIAFLEX or placebo. The primary efficacy endpoint will be the relative change in lipoma volume from baseline to 3 months, as determined by CT scan. We expect to complete enrollment in this study by the first half of 2013.
Other Clinical Indications
Other clinical indications for which our collagenase injection has been tested include keloids, hypertrophic scars, scarred tendons, glaucoma, herniated intervertebral discs, and as an adjunct to vitrectomy.
LICENSING AND MARKETING AGREEMENTS
Topical Collagenase Agreement
In connection with a March 2006 agreement (the “DFB Agreement”), pursuant to which we sold our topical collagenase business to DFB Biotech, Inc. and its affiliates (“DFB”), until March 2011 we received payments for certain technical assistance and certain transition services that we provided to DFB. Pursuant to the DFB Agreement, we currently receive earn out payments based on the sales of certain products, but our right to receive these payments expires at the end of August 2013. We expect to receive the final of these earn out payments by the end of 2013. The topical collagenase business of DFB was acquired by Smith & Nephew plc at the end of the fourth quarter of 2012. With our consent, DFB is expected to assign, and Smith & Nephew plc is expected to assume, the DFB Agreement.
As of December 31, 2012, we have received a total of $1.4 million in consulting fees; our right to receive these consulting fees expired in March 2011. In addition, we have recognized $2.9 million in earn out payments from DFB in connection with the net sales of topical collagenase in 2012.
Auxilium Agreement
Under the Auxilium Agreement, we granted to Auxilium exclusive worldwide rights to develop, market and sell certain products containing our injectable collagenase. Currently its licensed rights cover the indications of Dupuytren’s contracture, Peyronie’s disease, frozen shoulder and cellulite. Auxilium may further expand the Auxilium Agreement, at its exclusive option, to develop and license our injectable collagenase for use in additional indications. Pfizer has marketing rights for XIAPEX for Dupuytren’s contracture and Peyronie's disease in Europe and certain Eurasian countries through April 24, 2013. Auxilium has announced that it is currently evaluating strategic options for the continuing commercialization of XIAPEX for the treatment of Dupuytren’s contracture and for gaining approval for XIAPEX for the treatment of Peyronie’s disease in the EU and other specified markets when rights to commercialize XIAPEX and responsibility for regulatory activities for XIAPEX in these countries revert to Auxilium. Auxilium has granted to Asahi the exclusive right to develop and commercialize XIAFLEX for the treatment of Dupuytren’s contracture and Peyronie’s disease in Japan. Auxilium has granted to Actelion the exclusive right to develop and commercialize XIAFLEX for the treatment of Dupuytren’s contracture and Peyronie’s disease in Canada, Australia, Brazil and Mexico.
Through December 31, 2012, Auxilium has paid us up-front licensing and sublicensing fees and milestone payments under the Auxilium Agreement of $24.3 million, including amounts in connection with Auxilium’s agreements with Pfizer, Asahi and Actelion. In addition to the payments already received by us and to be received by us with respect to the Dupuytren’s contracture indication, Auxilium will be obligated to make contingent milestone payments to us, with respect to each of the Peyronie’s disease, frozen shoulder and cellulite indications, upon the acceptance of the regulatory filing (which has occurred in the U.S., in the case of Peyronie’s disease) and upon receipt by Auxilium, its affiliate or sublicensee of regulatory approval. The remaining contingent milestone payments that may be received, in the aggregate, from Auxilium in respect of these contingent milestones are $5.0 million.
Auxilium will also be obligated to make sublicense fee payments to us if it out-licenses to third parties the right to market and sell XIAFLEX for the treatment of frozen shoulder or cellulite. Additional milestone obligations will be due if Auxilium exercises its option to develop and license XIAFLEX for additional indications.
We are entitled to 8.5% of all sublicense income that Auxilium receives from Pfizer under their collaboration agreement, which payments are dependent on the achievement by Pfizer of certain regulatory and sales related milestones. Under this collaboration agreement, Auxilium received a $30 million milestone payment from Pfizer following the first sale of XIAPEX in the United Kingdom, which was the first major market country in which Pfizer sold XIAPEX, and we received from Auxilium $2.5 million in connection with that first sale. In connection with the launch of XIAPEX in each of Germany and Spain, we received from Auxilium 8.5% of each of the $7.5 million milestone payments from Pfizer to Auxilium, or $637,500. As of January 25, 2013, we have received $11.5
million in sublicensing fees and milestones related to the Auxilium’s collaboration agreement with Pfizer. Given the mutual termination by Auxilium and Pfizer of their collaboration agreement, we do not anticipate receiving any more sublicense income related to Pfizer. If Auxilium enters into an agreement with a third party related to the continuing commercialization of XIAPEX for the treatment of Dupuytren’s contracture and for gaining approval for XIAPEX for the treatment of Peyronie’s disease in the EU and other specified markets, we will be entitled to a specified percentage of sublicense agreement due under such agreement. In 2011, we received $750,000, or 5%, of the $15 million upfront payment Auxilium received from Asahi. In 2012, we received $570,000, or 5.7%, of the $10 million upfront payment Auxilium received from Actelion and $29,000 for approval in Canada of XIAFLEX for Dupuytren’s contracture. To the extent Auxilium enters into an agreement or agreements related to other territories, the percentage of sublicense income that Auxilium would pay us will depend on the stage of development and approval of XIAFLEX for the particular indication at the time such other agreement or agreements are executed.
Auxilium must pay us on a country-by-country and product-by-product basis a low double digit royalty as a percentage of net sales for products covered by the Auxilium Agreement and sold in the United States, Europe and certain Eurasian countries and Japan. In the case of products covered by the Auxilium Agreement and sold in other countries (the “Rest of the World”), Auxilium must pay us on a country-by-country and product-by-product basis a specified percentage of the royalties it is entitled to receive from a partner or partners with whom it has contracted for such countries (a “Rest of the World Partner”), which in the case of Canada, Australia, Brazil and Mexico is Actelion. The royalty rate is independent of sales volume and clinical indication in the United States, Europe and certain Eurasian countries and Japan, but is subject to set-off in those countries and the Rest of the World for certain expenses we owe to Auxilium relating to certain development and patent costs. In addition, the royalty percentage may be reduced if (i) market share of a competing product exceeds a specified threshold; or (ii) Auxilium is required to obtain a license from a third party in order to practice our patents without infringing such third party’s patent rights, although Auxilium has confirmed to us that no license from a third party is required. In addition, if Auxilium out-licenses to a third party, then we will receive a specified percentage of certain payments made to Auxilium in consideration of such out-licenses.
These royalty obligations extend, on a country-by-country and product-by-product basis, for the longer of the patent life (including pending patents), the expiration of any regulatory exclusivity period based on orphan drug designation or foreign equivalent thereof or June 3, 2016. Auxilium may terminate the Auxilium Agreement upon 90 days prior written notice. If Auxilium terminates the Auxilium Agreement other than because of an uncured, material breach by us, all rights revert to us. Pursuant to our August 31, 2011 settlement agreement with Auxilium, we are now co-owners and are or will be co-inventors of U.S. Patent No. 7,811,560 and any continuations and divisionals thereof. Auxilium expects this patent will expire in July 2028.
On top of the payments set forth above, Auxilium must pay to us an amount equal to a specified mark-up of the cost of goods sold for products sold in the United States, Europe and certain Eurasian countries or Japan. For products sold in the Rest of the World, Auxilium must pay to us a specified percentage of the mark-up of the cost of goods sold it is entitled to receive from a Rest of the World Partner, including Actelion, without regard to any set-offs that the Rest of the World Partner may have with respect to Auxilium.
Auxilium is generally responsible, at its own cost and expense, for developing the formulation and finished dosage form of products and arranging for the clinical supply of products. Auxilium is generally responsible for all clinical development and regulatory costs for Peyronie’s disease, Dupuytren’s contracture, frozen shoulder, cellulite and all additional indications for which it exercises its options.
A redacted copy of the Auxilium Agreement was filed on Form 8-K with the SEC on September 1, 2011. The foregoing descriptions of the Auxilium Agreement do not purport to be complete and are qualified in their entirety by reference to the full text of the Auxilium Agreement.
In-Licensing and Royalty Agreements
We have entered into several in-licensing and royalty agreements with various investigators, universities and other entities throughout the years.
Dupuytren’s Contracture
On November 21, 2006, we entered into a license agreement (the “Dupuytren’s License Agreement”) with the Research Foundation of the State University of New York at Stony Brook (the “Research Foundation”), pursuant to which the Research Foundation granted to us and our affiliates an exclusive worldwide license, with the right to sublicense to certain third parties, to know-how owned by the Research Foundation related to the development, manufacture, use or sale of (i) the collagenase enzyme obtained by a fermentation and purification process (the “Enzyme”), and (ii) all pharmaceutical products containing the Enzyme or injectable collagenase, in each case to the extent it pertains to the treatment and prevention of Dupuytren’s contracture.
In consideration of the license granted under the Dupuytren’s License Agreement, we agreed to pay to the Research Foundation certain royalties on net sales (if any) of pharmaceutical products containing the Enzyme or injectable collagenase for the treatment and prevention of Dupuytren’s contracture (each a “Dupuytren’s Licensed Product”).
Our obligation to pay royalties to the Research Foundation with respect to sales by us, our affiliates or any sublicensee of any Dupuytren’s Licensed Product in any country (including the U.S.) arises only upon the first commercial sale of such Dupuytren’s Licensed Product on a country-by-country basis. The royalty rate is 0.5% of net sales. Our obligation to pay royalties to the Research Foundation will continue until the later of (i) the expiration of the last valid claim of a patent pertaining to the Dupuytren’s Licensed Product; (ii) the expiration of the regulatory exclusivity period conveyed by the FDA’s Office of Orphan Products Development (“OOPD”) with respect to the Dupuytren’s Licensed Product; or (iii) June 3, 2016.
Unless terminated earlier in accordance with its termination provisions, the Dupuytren’s License Agreement and the licenses granted under that agreement will continue in effect until the termination of our royalty obligations. After that, all licenses granted to us under the Dupuytren’s License Agreement will become fully paid, irrevocable exclusive licenses.
A redacted copy of the Dupuytren’s License Agreement was filed on Form 8-K with the SEC on November 28, 2006. The foregoing descriptions of the Dupuytren’s License Agreement do not purport to be complete and are qualified in their entirety by reference to the full text of the Dupuytren’s License Agreement.
Peyronie’s Disease
On August 27, 2008, we entered into an agreement with Dr. Martin K. Gelbard to improve the deal terms related to our future royalty obligations for Peyronie’s disease by buying down our future royalty obligations with a one-time cash payment. A redacted copy of the agreement was filed on Form 8-K with the SEC on September 5, 2008. On March 31, 2012, we entered into an amendment to this agreement, which enables us to buy down a portion of our future royalty obligations in exchange for an initial cash payment and five additional cash payments payable upon the occurrence of a milestone event. A redacted copy of the amendment was filed on Form 8-K/A with the SEC on August 8, 2012. The foregoing descriptions of the agreement with Dr. Gelbard and the amendment to that agreement do not comport to be complete and are qualified in their entirety by reference to the full text of that agreement, as amended.
Frozen Shoulder
On November 21, 2006, we entered into a license agreement (the “Frozen Shoulder License Agreement”) with the Research Foundation, pursuant to which the Research Foundation granted to us and our affiliates an exclusive worldwide license, with the right to sublicense to certain third parties, to know-how owned by the Research Foundation related to the development, manufacture, use or sale of (i) the Enzyme and (ii) all pharmaceutical products containing the Enzyme or injectable collagenase, in each case to the extent it pertains to the treatment and prevention of frozen shoulder. Additionally, the Research Foundation granted to us an exclusive license to the patent applications in respect of frozen shoulder. The license granted to us under the Frozen Shoulder License Agreement is subject to the non-exclusive license (with right to sublicense) granted to the U.S. government by the Research Foundation in connection with the U.S. government’s funding of the initial research.
In consideration of the license granted under the Frozen Shoulder License Agreement, we agreed to pay to the Research Foundation certain royalties on net sales (if any) of pharmaceutical products containing the Enzyme or injectable collagenase for the treatment and prevention of frozen shoulder (each a “Frozen Shoulder Licensed Product”). In addition, we and the Research Foundation will share in any milestone payments and sublicense income received by us in respect of the rights licensed under the Frozen Shoulder License Agreement.
Our obligation to pay royalties to the Research Foundation with respect to sales by us, our affiliates or any sublicensee of any Frozen Shoulder Licensed Product in any country (including the U.S.) arises only upon the first commercial sale of a Frozen Shoulder Licensed Product. Our obligation to pay royalties to the Research Foundation will continue until, the later of (i) the expiration of the last valid claim of a patent pertaining to a Frozen Shoulder Licensed Product or (ii) June 3, 2016.
Unless terminated earlier in accordance with its termination provisions, the Frozen Shoulder License Agreement and licenses granted under that agreement will continue in effect until the termination of our royalty obligations. After that, all licenses granted to us under the Frozen Shoulder License Agreement will become fully paid, irrevocable exclusive licenses.
A redacted copy of the Frozen Shoulder License Agreement was filed on Form 8-K with the SEC on November 28, 2006. The foregoing descriptions of the Frozen Shoulder License Agreement do not purport to be complete and are qualified in their entirety by reference to the full text of the Frozen Shoulder License Agreement.
In connection with the execution of the Dupuytren’s License Agreement and the Frozen Shoulder License Agreement, we made certain up-front payments to the Research Foundation and the clinical investigators working on the Dupuytren’s contracture and frozen shoulder indications for the Enzyme.
Cellulite
We have two in-licensing and royalty agreements related to cellulite. One is a license agreement (the “Cellulite License Agreement”) with the Research Foundation that we entered into on August 23, 2007. Pursuant to the Cellulite License Agreement, the Research Foundation granted to us and our affiliates an exclusive worldwide license, with the right to sublicense to certain third parties, to know-how owned by the Research Foundation related to the manufacture, preparation, formulation, use or development of (i) the Enzyme and (ii) all pharmaceutical products containing the Enzyme, which are made, used and sold for the prevention or treatment of cellulite. Additionally, the Research Foundation granted to us an exclusive license to the patent applications in respect of cellulite. The license granted to us under the Cellulite License Agreement is subject to the non-exclusive license (with right to sublicense) granted to the U.S. government by the Research Foundation in connection with the U.S. government’s funding of the initial research.
In consideration of the license granted under the Cellulite License Agreement, we agreed to pay to the Research Foundation certain royalties on net sales (if any) of pharmaceutical products containing the Enzyme, which are made, used and sold for the prevention or treatment of cellulite (each a “Cellulite Licensed Product”). In addition, we and the Research Foundation will share in any milestone payments and sublicense income received by us in respect of the rights licensed under the Cellulite License Agreement. We paid a portion of the $500,000 milestone payment we received from Auxilium in respect of its exercise of cellulite as an addition indication under the Auxilium Agreement, subject to certain credits for certain up-front payments we made to the Research Foundation.
Our obligation to pay royalties to the Research Foundation with respect to sales by us, our affiliates or any sublicensee of any Cellulite Licensed Product in any country (including the U.S.) arises only upon the first commercial sale of a Cellulite Licensed Product. Our obligation to pay royalties to the Research Foundation will continue until, the later of (i) the expiration of the last valid claim of a patent pertaining to a Cellulite Licensed Product or (ii) June 3, 2016.
Unless terminated earlier in accordance with its termination provisions, the Cellulite License Agreement and licenses granted under that agreement will continue in effect until the termination of our royalty obligations. After that, all licenses granted to us under the Cellulite License Agreement will become fully paid, irrevocable exclusive licenses.
The other in-licensing and royalty agreement we have related to cellulite is a license agreement with Dr. Zachary Gerut that we entered into on March 27, 2010 (the “Gerut License Agreement”). Pursuant to the Gerut License Agreement, Dr. Gerut granted to us and our affiliates an exclusive worldwide license, with the right to sublicense to certain third parties to know-how owned by Dr. Gerut related to the manufacture, preparation, formulation, use or development of (i) the Enzyme and (ii) all pharmaceutical products containing the Enzyme or injectable collagenase, in each case to the extent it pertains to the treatment of fat. As the in-license granted in the Gerut License Agreement pertains to the treatment of fat, this in-license also relates to human lipoma and canine lipoma.
In consideration of the license granted under the Gerut License Agreement, we agreed to pay to Dr. Gerut certain royalties on net sales (if any) of pharmaceutical products containing the Enzyme which are made, used and sold for the removal or treatment of fat in humans or animals (each a “Gerut Licensed Product”). In addition, in the event the FDA approves a Gerut Licensed Product, we have agreed to make a one-time stock option grant to Dr. Gerut with a strike price equal to the closing trading price on the day before the date of such grant.
Our obligation to pay royalties to Dr. Gerut with respect to sales by us, our affiliates or any sublicensee of any Gerut Licensed Product in any country (including the U.S.) arises only upon the first commercial sale of a Gerut Licensed Product. Our obligation to pay royalties to Dr. Gerut will continue until June 3, 2016 or such longer period as we continue to receive royalties for such Gerut Licensed Product.
Unless terminated earlier in accordance with its termination provisions, the Gerut License Agreement and licenses granted under that agreement will continue in effect until the termination of our royalty obligations. After that, all licenses granted to us under the Gerut License Agreement will become fully paid, irrevocable exclusive licenses.
Redacted copies of the Cellulite License Agreement and the Gerut License Agreement are being filed with this Report. The foregoing descriptions of the Cellulite License Agreement and the Gerut License Agreement do not purport to be complete and are qualified in their entirety by reference to the full text of these agreements.
Other Indications
We have or may enter into certain other license and royalty agreements with respect to other indications that we may elect to pursue.
COMPETITION
We and our licensees face worldwide competition from larger pharmaceutical companies, specialty pharmaceutical companies and biotechnology firms, universities and other research institutions and government agencies that are developing and commercializing pharmaceutical products. Many of our competitors have substantially greater financial, technical and human resources than we have and may subsequently develop products that are more effective, safer or less costly than any products that we have developed, are developing or will develop, or that are generic products. Our success will depend on our ability to acquire, develop and commercialize products and our ability to establish and maintain markets for our products that receive marketing approval.
COST OF RESEARCH AND DEVELOPMENT ACTIVITIES
During fiscal years 2012 and 2011, the Company invested $1,249,755 and $972,078, respectively, in research and development activities.
GOVERNMENT REGULATION
Any product labeled for use in humans requires regulatory approval by government agencies prior to commercialization. In particular, human therapeutic products are subject to rigorous preclinical and clinical trials to demonstrate safety and efficacy
and other approval procedures of the FDA and similar regulatory authorities in foreign countries. Various federal, state, local, and foreign statutes and regulations also govern testing, manufacturing, labeling, distribution, storage, and record-keeping related to such products and their promotion and marketing. The process of obtaining these approvals and the compliance with federal, state, local, and foreign statutes and regulations require the expenditure of substantial time and financial resources. In addition, the current political environment and the current regulatory environment at the FDA could lead to increased testing and data requirements which could impact regulatory timelines and costs.
Clinical trials involve the administration of the investigational product candidate or approved products to human subjects under the supervision of qualified investigators. Clinical trials are conducted under protocols detailing, among other things, the objectives of the study and the parameters to be used in assessing the safety and the effectiveness of the drug. Typically, clinical evaluation involves a time-consuming and costly three-phase sequential process, but the phases may overlap. Each trial must be reviewed, approved and conducted under the auspices of an independent institutional review board, and each trial must include the patient’s informed consent.
Clinical testing may not be completed successfully within any specified time period, if at all. The FDA monitors the progress of all clinical trials that are conducted in the U.S. and may, at its discretion, reevaluate, alter, suspend or terminate the testing based upon the data accumulated to that point and the FDA’s assessment of the risk/benefit ratio to the patient. The FDA can also provide specific guidance on the acceptability of protocol design for clinical trials. The FDA, we or our partners may suspend or terminate clinical trials at any time for various reasons, including a finding that the subjects or patients are being exposed to an unacceptable health risk. The FDA can also request that additional clinical trials be conducted as a condition to product approval. During all clinical trials, physicians monitor the patients to determine effectiveness and/or to observe and report any reactions or other safety risks that may result from use of the drug candidate.
Assuming successful completion of the required clinical trials, drug developers submit the results of preclinical studies and clinical trials, together with other detailed information including information on the chemistry, manufacture and control of the product, to the FDA, in the form of an NDA or BLA, requesting approval to market the product for one or more indications. In most cases, the NDA/BLA must be accompanied by a substantial user fee. The FDA reviews an NDA/BLA to determine, among other things, whether a product is safe and effective for its intended use.
Before approving an NDA or BLA, the FDA will inspect the facility or facilities where the product is manufactured. The FDA will not approve the NDA or BLA unless cGMP compliance is satisfactory. The FDA will issue an approval letter if it determines that the NDA or BLA, manufacturing process and manufacturing facilities are acceptable. If the FDA determines that the NDA or BLA, manufacturing process or manufacturing facilities are not acceptable, it will outline the deficiencies in the submission and will often request additional testing or information. Notwithstanding the submission of any requested additional information, the FDA ultimately may decide that the NDA or BLA does not satisfy the regulatory criteria for approval and refuse to approve the NDA or BLA by issuing a “not approvable” letter.
The testing and approval process requires substantial time, effort and financial resources, which may take several years to complete. The FDA may not grant approval on a timely basis, or at all. We or our partners may encounter difficulties or unanticipated costs in our or their efforts to secure necessary governmental approvals, which could delay or preclude us or them from marketing our products. Furthermore, the FDA may prevent a drug developer from marketing a product under a label for its desired indications or place other conditions, including restrictive labeling, on distribution as a condition of any approvals, which may impair commercialization of the product. After approval, some types of changes to the approved product, such as adding new indications, manufacturing changes and additional labeling claims, are subject to further FDA review and approval.
If the FDA approves the NDA or BLA, the drug can be marketed to physicians to prescribe in the U.S. After approval, the drug developer must comply with a number of post-approval requirements, including delivering periodic reports to the FDA (i.e., annual reports), submitting descriptions of any adverse reactions reported, biological product deviation reporting, and complying with drug sampling and distribution requirements and any other requirements set forth in the FDA’s approval (such as the REMS program, which the FDA has required for XIAFLEX and consists of a communication plan and a medication guide). The holder of an approved NDA/BLA is required to provide updated safety and efficacy information and to comply with requirements concerning advertising and promotional labeling. Also, quality control and manufacturing procedures must continue to conform to cGMP after approval. Drug manufacturers and their subcontractors are required to register their facilities and are subject to periodic unannounced inspections by the FDA to assess compliance with cGMP which impose procedural and documentation requirements relating to manufacturing, quality assurance and quality control. Accordingly, manufacturers must continue to expend time, money and effort in the area of production and quality control to maintain compliance with cGMP and other regulatory requirements. The FDA may require post-market testing and surveillance to monitor the product’s safety or efficacy, including additional studies to evaluate long-term effects.
In addition to studies requested by the FDA after approval, a drug developer may conduct other trials and studies to explore use of the approved drug for treatment of new indications, which require submission of a supplemental or new NDA/BLA and FDA approval of the new labeling claims. The purpose of these trials and studies is to broaden the application and use of the drug and its acceptance in the medical community.
We use, and will continue to use, third party manufacturers to produce our products in clinical quantities. Future FDA inspections may identify compliance issues at our facilities, at the facilities of our contract manufacturers or at those of our partners that may disrupt production or distribution, or require substantial resources to correct. In addition, discovery of problems with a product or the failure to comply with requirements may result in restrictions on a product, manufacturer or holder of an approved NDA/BLA, including withdrawal or recall of the product from the market or other voluntary or FDA-initiated action that could delay further marketing. Newly discovered or developed safety or effectiveness data may require changes to a product’s approved labeling, including the addition of new warnings and contraindications. Also, new government requirements may be established that could delay or prevent regulatory approval of our products under development.
INTELLECTUAL PROPERTY AND RIGHTS
Our success will depend in part on our ability to protect our existing products and the products we acquire or in-license by obtaining and maintaining a strong proprietary position both in the U.S. and in other countries. To develop and maintain such a position, we intend to continue relying upon patent protection, trade secrets, know-how, continuing technological innovations and licensing opportunities. In addition, we intend to seek patent protection whenever available for any products or product candidates and related technology we develop or acquire in the future.
Patents
We are the assignee or licensee of various U.S. patents, which have received patent protection in various foreign countries. Pursuant to our August 31, 2011 settlement agreement with Auxilium, we are now co-owners and either have been or will be added as co-inventors of U.S. Patent No. 7,811,560 and any continuations and divisionals thereof. Auxilium expects this patent will expire in July 2028. In addition, we have licenses to other pending patent applications. Although we believe these patent applications, if they issue as patents, will provide a competitive advantage, the scope of the patent positions of pharmaceutical firms involves complex legal, scientific and factual questions and, as such, is generally uncertain. In addition, the coverage claimed in a patent application can be significantly reduced before the patent is issued. Consequently, we do not know whether any of our current patent applications, or the products or product candidates we develop, acquire or license will result in the issuance of patents or, if any patents are issued, whether they will provide significant proprietary protection, will be of any value to us or will be challenged, circumvented or invalidated by our competitors or otherwise.
While we attempt to ensure that our product candidates and the methods we employ to manufacture them do not infringe other parties’ patents and proprietary rights, competitors or other parties may assert that we infringe their proprietary rights. Because patent applications in the U.S. and some other jurisdictions can proceed in secrecy until patents issue, third parties may obtain other patents without our knowledge prior to the issuance of patents relating to our product candidates, which they could attempt to assert against us. Also, since publication of discoveries in the scientific or patent literature often lags behind actual discoveries, we cannot be certain of the priority of inventions covered by pending patent applications. Moreover, we may have to participate in interference proceedings declared by the U.S. Patent and Trademark Office (the “USPTO”) to determine priority of invention, or in opposition proceedings in the USPTO, either of which could result in substantial cost to us, even if the eventual outcome is favorable to us. In the U.S., issued patents may be broadened, narrowed or even canceled as a result of post-issuance procedures instituted by us or third parties, including reissue, ex parte reexamination, and the new inter partes review, post grant review, and supplemental examination procedures enacted as part of the Leahy-Smith America Invents Act. There can be no assurance that the patents, if issued and challenged in a court of competent jurisdiction, would be found valid or enforceable. An adverse outcome could subject us to significant liabilities to third parties, require disputed rights to be licensed from third parties or require us to cease using such technology.
Although we believe that our product candidates, production methods and other activities do not currently infringe the intellectual property rights of third parties, we cannot be certain that a third party will not challenge our position in the future. If a third party alleges that we are infringing its intellectual property rights, we may need to obtain a license from that third party, but there can be no assurance that any such license will be available on acceptable terms or at all. Any infringement claim that results in litigation could result in substantial cost to us and the diversion of management’s attention from our core business. To enforce patents issued, assigned or licensed to us or to determine the scope and validity of other parties’ proprietary rights, we may also become involved in litigation or in interference proceedings declared by the USPTO, which could result in substantial costs to us or an adverse decision as to the priority of our inventions. We may be involved in interference and/or opposition proceedings in the future. We believe there will continue to be litigation in our industry regarding patent and other intellectual property rights.
We licensed to Auxilium our injectable collagenase for the treatment of Dupuytren’s contracture, Peyronie’s disease, frozen shoulder and cellulite. We have two use patents in the U.S. covering the enzyme underlying our injectable collagenase, one for the treatment of Dupuytren’s contracture, which issued from a reissue proceeding in December 2007, and one for the treatment of Peyronie’s disease. The Dupuytren’s patent expires in 2014, and the Peyronie’s patent expires in 2019. Both the Dupuytren’s and Peyronie’s patents are limited to the use of the enzyme for the treatment of Dupuytren’s contracture and Peyronie’s disease within certain dose ranges. An application to extend the term of the Dupuytren’s patent to August 22, 2019 based upon regulatory delay in granting approval to sell XIAFLEX was filed in the USPTO on April 1, 2010. The USPTO has not taken any action on the request for extension, and we cannot be certain how much of an extension, if any, will be granted by the USPTO.
Orphan Drug Designations
Two indications, Dupuytren’s contracture and Peyronie’s disease, have received orphan drug designation from the OOPD. These indications did not receive the European equivalent of orphan drug designation.
The OOPD administers the major provisions of the Orphan Drug Act, an innovative program that provides incentives for sponsors to develop products for rare diseases.
The incentives for products that qualify under the Orphan Drug Act include seven-year exclusive marketing rights post-FDA approval (which means, with respect to Dupuytren’s contracture, exclusivity until February 2, 2017), tax credits for expenses associated with clinical trials including a 20 year tax carry-forward, availability of FDA grants, and advice on design of the clinical development plan.
The orphan drug provisions of the Federal Food, Drug, and Cosmetic Act also provide incentives to drug and biologics suppliers to develop and supply drugs for the treatment of rare diseases, currently defined as diseases that affect fewer than 200,000 individuals in the U.S. or, for a disease that affects more than 200,000 individuals in the U.S. and for which there is no reasonable expectation that the cost of developing and making available in the U.S. a drug for such disease or condition will be recovered from its sales in the U.S. Under these provisions, a supplier of a designated orphan product can seek tax benefits, and the holder of the first FDA approval of a designated orphan product will be granted a seven-year period of marketing exclusivity for that product for the orphan indication. It would not prevent other drugs from being approved for the same indication.
In the Auxilium 10-K, Auxilium stated that “[w]hile XIAFLEX does not have orphan drug status for any indication in Europe, foreign patents cover these products in certain countries, and on approval of XIAFLEX for a first indication in Europe, we believe the product will benefit from ten years of market exclusivity and eight years of data exclusivity. We may obtain an additional year of market exclusivity if the regulatory authorities approve an additional indication that they determine to represent a significant clinical benefit.” Our royalty term, however, is not extended by any period of marketing exclusivity as contrasted with any period of orphan drug status or foreign equivalent thereof.
Trade Secrets
We also rely on trade secret protection for our confidential and proprietary information. No assurance can be given that others will not independently develop substantially equivalent proprietary information and techniques or otherwise gain access to our trade secrets or disclose such technology or that we can meaningfully protect our trade secrets.
It is our policy to require certain employees, consultants, outside scientific collaborators, sponsored researchers and other advisors to execute confidentiality agreements upon the commencement of employment or consulting relationships with us. These agreements provide that all confidential information developed or made known to the individual during the course of the individual’s relationship with us is to be kept confidential and not disclosed to third parties except in specific circumstances. In the case of employees, the agreements provide that all inventions conceived by the individual shall be our exclusive property. There can be no assurance, however, that these agreements will provide meaningful protection or adequate remedies for our trade secrets in the event of unauthorized use or disclosure of such information.

In addition to the other information included in this Report, the following factors should be considered in evaluating our business and future prospects. Any of the following risks, either alone or taken together, could materially and adversely affect our business, financial position or results of operations. If one or more of these or other risks or uncertainties materialize or if our underlying assumptions prove to be incorrect, our actual results may vary materially from what we projected. There may be additional risks that we do not presently know or that we currently believe are immaterial which could also impair our business or financial position.
Risks Related to Our Limited Sources of Revenue
Our future revenue is primarily dependent upon option, milestone and contingent royalty payments from Auxilium and contingent earn out payments from DFB.
Our primary sources of revenues are from (i) option, milestone and contingent royalty
payments from Auxilium under the Auxilium Agreement and (ii) contingent earn out payments from DFB.
As described in Item 1 above, under the Auxilium Agreement, in exchange for the right to receive royalties and other payments, we granted to Auxilium the right to develop, manufacture, market and sell worldwide products (other than dermal formulations for topical administration) that contain collagenase for the treatment of Dupuytren’s contracture, Peyronie’s disease, frozen shoulder and cellulite. However, we have no control over Auxilium’s ability to successfully market, sell and manufacture candidate products for the treatment of Dupuytren’s contracture, or, in the case of Peyronie’s disease, frozen shoulder and cellulite, to pursue commercialization, and we may receive limited, if any, royalty payments from Auxilium. We have received in the past, and are entitled to receive in the future, certain milestone payments from Auxilium in respect of its efforts to commercialize candidate products, but we have no control over Auxilium’s ability to achieve the milestones. As also described in Item 1 above, Auxilium has sublicensed to third parties some of the development and commercialization rights it licenses from us. We have received in the past a percentage of sublicense income that Auxilium receives from these third parties based on the achievement of certain regulatory and sales related milestones. There is no guarantee that these third parties will continue to pursue development and commercialization of XIAFLEX. If any third party stops pursuing such development and commercialization, sublicense income would no longer be payable to Auxilium or us. For example, Auxilium and Pfizer have agreed to terminate their collaboration agreement on April 24, 2013, at which time rights to develop and commercialize XIAPEX in Europe and certain Eurasian countries will revert to Auxilium and no further milestones will be due under the Pfizer/Auxilium collaboration agreement. Auxilium has not announced its plans for when these rights revert to Auxilium. Auxilium has stated that it is currently committed to continuing to commercialize XIAPEX for the treatment of Dupuytren’s contracture and continuing to develop XIAPEX if approved for the treatment of Peyronie’s disease in this territory, but has noted that it “may not have adequate resources or capabilities to do so on [its] own, [it] may not be successful in entering into a new collaboration agreement with a new partner, and continued commercialization may not be profitable for [it]. Also, [Auxilium] may not be successful in completing all actions necessary for the transfer of the Marketing Authorization to it”. Future sublicense income, if any, related to development and commercialization of XIAFLEX for Dupuytren’s contracture and Peyronie’s disease in Europe and certain Eurasian countries will depend upon whether Auxilium enters into an agreement with a third party with respect to those activities, and it is unclear whether Auxilium will do so.
Even if Auxilium or its sublicensees pursues development and commercialization, there is no guarantee that the FDA will approve XIAFLEX for a given indication or that commercialization will be successful, if the FDA does approve XIAFLEX for a given indication. Moreover, under the Auxilium Agreement, royalty payments are subject to set-off for certain expenses we owe Auxilium related to development and patent costs. We received our first royalty payment from Auxilium in November 2011 because the amount of royalties exceeded accrued set-off expenses for the first time. We anticipate that the amount of royalties due to us will exceed the amount of any set-offs on a going forward basis.
In addition, we have granted to Auxilium an option to expand its license and development rights to one or more additional indications for injectable collagenase not currently licensed to Auxilium, including for the treatment of human and canine lipoma. If Auxilium exercises its option with respect to an additional indication, we are entitled to receive a one-time license fee for the rights to, as well as potential milestone, royalty and other payments with respect to, such new indication. If Auxilium does not exercise its option as to any additional indication, we may offer to any third party such development rights with regard to products in the Auxilium Territory (as defined in the Auxilium Agreement), provided that we first offer the same terms to Auxilium, or develop the product ourselves.
Auxilium has no obligation to exercise its option with respect to any such additional indication, and its decision to do so is in its complete discretion. Clinical trials can be expensive and the results are subject to different interpretations, therefore, there is no assurance that after conducting phase II clinical trials on any additional indication, and incurring the associated expenses, Auxilium will exercise its option or we will receive any revenue from it. Under the Auxilium Agreement, we may only offer to a third party development rights with regard to products in the Auxilium Territory and not in Europe and certain Eurasian countries. Even if Auxilium exercises its option as to any additional indication, its obligations to develop the product for such indication are limited to initiating Stage II Development (as defined in the Auxilium Agreement) for such additional indication within one year of exercising the option as to such indication. Auxilium may decide to allocate its resources other than to the development of XIAFLEX, and we have no control over that decision. Auxilium recently announced the issuance of $350 million in the aggregate principal amount of 1.50% Convertible Senior Notes due 2018, the net proceeds from which, according to Auxilium, are to be used, among other things, “for general corporate purposes, which may include the acquisition (including by merger, purchase, license or otherwise) of businesses, products, product rights or technologies”. Any such non-XIAFLEX related acquisition may result in Auxilium reallocating its priorities away from XIAFLEX.
As part of the sale of our topical collagenase business to DFB, we are entitled to receive earn out payments in respect of sales of certain products developed and manufactured by DFB that contain collagenase for topical administration. However, our right to receive earn out payments from DFB is dependent upon DFB’s decision to pursue the manufacture and commercialization of such products and its ability to achieve certain sales thresholds. In addition, DFB’s obligations to make earn-out payments to us terminate in August 2013 and we expect to receive our last earn-out payment by the end of 2013.
Our dependence upon revenue from Auxilium make us subject to the commercialization and other risk factors affecting Auxilium over which we have limited or no control.
Auxilium has disclosed in its securities filings a number of risk factors to consider when evaluating its business and future prospects. Given our dependence upon revenue from Auxilium, Auxilium’s operating success or failure has a significant impact on our potential royalty stream and other payment rights. As such, we refer you to the full text of Auxilium’s disclosed risk factors in its securities filings, which were most recently included in the Auxilium 10-K.
If we are unable to obtain option, milestone, earn out and royalty payments from Auxilium or DFB or meet our needs for additional funding from other sources, we may be required to limit, scale back or cease our operations.
Our business strategy contains elements that we will not be able to implement if we do not receive the anticipated option, milestone, royalty or earn out payments from Auxilium or DFB, or secure additional funding from other sources. While we anticipate being profitable on an ongoing, annual basis, our future funding requirements will depend on many factors, including:
|
|
The ability of DFB and its successor, Smith & Nephew plc, to meet its payment obligations and to manufacture and commercialize topical collagenase products for which we would receive earn out payments until August 2013, payable by the end of 2013;
|
|
·
|
Auxilium’s ability to manufacture and commercialize XIAFLEX for which we would receive milestone and royalty payments;
|
|
·
|
whether Auxilium finds another partner to develop and commercialize XIAPEX in Europe and certain Eurasian countries following the termination of Auxilium’s collaboration with Pfizer on April 24, 2013 (for more information regarding Auxilium’s plans with respect to the development and commercialization of XIAPEX in Europe and certain Eurasian countries, we refer you to the Auxilium 10-K);
|
|
·
|
Actelion’s ability to commercialize XIAFLEX in Canada;
|
|
|
the amount actually owed to Auxilium for certain patent costs;
|
|
|
the scope, rate of progress, cost and results of our clinical trials on additional indications, including human and canine lipoma, for which Auxilium could exercise its option to acquire rights to them, and whether Auxilium exercises the option;
|
|
·
|
the terms and timing of any future collaborative, licensing, co-promotion and other arrangements that we may establish;
|
|
·
|
the cost of filing, prosecuting, defending and enforcing any patent claims and other intellectual property rights or defending against any other litigation; and
|
|
|
whether Auxilium acquires a new product or technology, which results in Auxilium’s reallocation of priority away from XIAFLEX.
|
These factors could result in variations from our currently projected operating requirements. If our existing resources are insufficient to satisfy our operating requirements, we may need to limit, scale back or cease operations or, in the alternative, borrow money. Given our operations and history, we may not be able to borrow money on commercially reasonable terms, if at all. If we issue any equity or debt securities, the terms of such issuance may not be acceptable to us and would likely result in substantial dilution of our stockholders’ investment. If we do not receive revenues from Auxilium or DFB, and are unable to secure additional financing, we may be required to cease operations.
In order to finance and to secure the rights to conduct clinical trials for products we have licensed to Auxilium, we have granted to third parties significant rights to share in royalty payments received by us.
To finance and secure the rights to conduct clinical trials for products we have licensed to Auxilium, we have granted to third parties certain rights to share in royalty payments received by us from Auxilium under the Auxilium Agreement. Consequently, we will be required to share a significant portion of the payments due to us from Auxilium under the Auxilium Agreement.
If we breach our agreements with third parties, our business could be materially harmed.
Our agreements with third parties impose on us various obligations, such as those related to intellectual property rights, non-competition, and development of products, as described throughout this Item 1A of this Report. If we fail to comply with such obligations, or a counterparty to our agreements believes that we have failed to comply with such obligations, we may be sued and the costs of the resulting litigation could materially harm our business.
Risks Related to Clinical Trials and Development of Drug Candidates
Our ability to conduct clinical trials may be limited by the Auxilium Agreement.
Under the Auxilium Agreement, we have the right to conduct trials, studies or development work for, among other things, indications in canine lipomas and human lipomas, and, upon approval by the parties’ joint development committee (“JDC”), additional indications. Auxilium has pre-approved our protocols for canine lipomas and human lipomas. However, certain material changes to the protocols must be approved by the JDC, and the JDC may decide not to approve such changes if the JDC has reasonable safety concerns. In addition, the JDC has the right to stop a study or trial in canine lipomas and human lipomas if the rate of serious adverse events exceeds certain thresholds. If the JDC fails to approve changes to our protocols for canine lipomas and human lipomas or if the JDC stops our studies or trials in canine lipomas and human lipomas due to safety concerns, our ability to obtain option, milestone and royalty payments with respect to those indications would be limited. We may only conduct trials, studies or development work for additional indications beyond the pre-approved indications upon submission to and approval by the JDC of our development plan. In the case of indications in keloids, capsular contraction after breast augmentation, arthrofibrosis following total joint replacement in humans and equine suspensory ligament desmitis, the JDC may reject our submission only for reasonable safety concerns. The JDC may reject our submission for any other additional indications for safety or commercial concerns. If the JDC rejects our submissions in any additional indications, our ability to obtain option, milestone and royalty payments with respect to those additional indications would be limited.
We are dependent on Auxilium for access to XIAFLEX, which may limit our ability to conduct clinical trials and to obtain the associated option, milestone and contingent royalty payments under the Auxilium Agreement.
Under the Auxilium Agreement, we have agreed to buy at cost plus a mark-up XIAFLEX from Auxilium for conducting our trials, studies and development work. If Auxilium does not supply XIAFLEX to us, our ability to conduct clinical trials using XIAFLEX would be limited because we do not have the right to make XIAFLEX or to purchase it from third parties. Moreover, our ability to use our own clinical material may be limited both by lack of availability and by certain potential regulatory restrictions. Without adequate supply of clinical material our ability to obtain additional option, milestone and royalty payments under the Auxilium Agreement would be limited.
If clinical trials in humans or veterinarian trials for our potential new indications are delayed, we may not be able to obtain option, milestone or royalty payments under the Auxilium Agreement for new indications.
Clinical trials that we or our investigators may conduct may not begin on time or may need to be restructured or temporarily suspended after they have begun. Clinical trials can be delayed or may need to be restructured for a variety of reasons, including delays or restructuring related to:
|
·
|
changes to the regulatory approval process for product candidates;
|
|
·
|
obtaining regulatory approval to commence a clinical trial;
|
|
·
|
timing of responses required from regulatory authorities;
|
|
·
|
negotiating acceptable clinical trial agreement terms with prospective investigators or trial sites;
|
|
·
|
obtaining institutional review board, or equivalent, approval to conduct a clinical trial at a prospective site;
|
|
·
|
recruiting subjects to participate in a clinical trial;
|
|
·
|
competition in recruiting clinical investigators;
|
|
·
|
shortage or lack of availability of clinical trial supplies from external and internal sources;
|
|
·
|
the need to repeat clinical trials as a result of inconclusive results or poorly executed testing;
|
|
·
|
failure to validate a patient-reported outcome questionnaire;
|
|
·
|
the placement of a clinical hold on a study;
|
|
·
|
the failure of third parties conducting and overseeing the operations of our clinical trials to perform their contractual or regulatory obligations in a timely fashion; and
|
|
·
|
exposure of clinical trial subjects to unexpected and unacceptable health risks or noncompliance with regulatory requirements, which may result in suspension of the trial.
|
The process of conducting clinical trials and developing product candidates involves a high degree of risk, may take several years, and may ultimately not be successful.
Product candidates that appear promising in the early phases of development may fail to reach the market for several reasons, including:
|
|
clinical trials may show product candidates to be ineffective or not as effective as anticipated or to have harmful side effects or any unforeseen result;
|
|
·
|
product candidates may fail to receive regulatory approvals required to bring the products to market;
|
|
|
manufacturing costs, the inability to scale up to produce supplies for clinical trials or other factors may make our product candidates uneconomical; and
|
|
|
the proprietary rights of others and their competing products and technologies may prevent product candidates from being effectively commercialized or from obtaining exclusivity.
|
Success in preclinical and early clinical trials does not ensure that large-scale clinical trials will be successful. Clinical results are frequently susceptible to varying interpretations that may delay, limit or prevent regulatory approvals. The length of time necessary to complete clinical trials and to submit an application for marketing approval for a final decision by a regulatory authority varies significantly and may be difficult to predict. Any changes to the U.S. regulatory approval process could significantly increase the timing or cost of regulatory approval for product candidates making further development uneconomical or impossible. In addition, once Auxilium exercises its option with respect to an additional indication, further clinical trials, development, manufacturing, marketing and selling of such product are out of our control. Our interest is limited to receiving option, milestone and royalty payments.
Successful development of drug candidates is inherently difficult and uncertain, and our long-term prospects depend upon our ability and the ability of our partners, particularly with respect to XIAFLEX, to continue to successfully commercialize these drug candidates.
Successful development of drugs is inherently difficult and uncertain. Our business requires investments in research and development over many years, often for drug candidates that may fail during the research and development process. Even if the Company is able to successfully complete the development of our drug candidates, our long-term prospects depend upon our ability and the ability of our partners, particularly with respect to XIAFLEX, to continue to successfully commercialize these drug candidates.
There is significant uncertainty regarding our ability to successfully develop drug candidates in other indications. These risks include the uncertainty of:
|
·
|
the nature, timing and estimated costs of the efforts necessary to complete the development of our drug candidate projects;
|
|
·
|
the anticipated completion dates for our drug candidate projects;
|
|
·
|
the scope, rate of progress and cost of our clinical trials that we are currently running or may commence in the future with respect to our drug candidate projects;
|
|
·
|
the scope, rate of progress of our preclinical studies and other research and development activities related to our drug candidate projects;
|
|
·
|
clinical trial results for our drug candidate projects;
|
|
·
|
the cost of filing, prosecuting, defending and enforcing any patent claims and other intellectual property rights relating to our drug candidate projects;
|
|
·
|
the terms and timing of any strategic alliance, licensing and other arrangements that we have or may establish in the future relating to our drug candidate projects;
|
|
·
|
the cost and timing of regulatory approvals with respect to our drug candidate projects; and
|
|
·
|
the cost of establishing clinical supplies for our drug candidate projects.
|
Risks Related to Our Agreements with Auxilium and DFB
Our ability to conduct clinical trials and develop products for injectable administration of collagenase is limited by the Auxilium Agreement.
Under the Auxilium Agreement, we have licensed or granted options to certain of our rights to conduct clinical trials and develop products for injectable administration of collagenase. We agreed, for example, to certain non-competition provisions, which may limit our clinical development activities.
Our ability to conduct clinical trials and develop products for topical administration of collagenase is limited by the agreement we have signed with DFB.
Under the DFB Agreement, we have sold, licensed, or granted options to certain of our rights to conduct clinical trials and develop products for topical administration of collagenase. Under the terms of the DFB Agreement, we have agreed to certain non-competition provisions, which may limit our clinical development activities.
Risks Related to Regulatory Requirements
We are subject to numerous complex regulatory requirements and failure to comply with these regulations, or the cost of compliance with these regulations, may harm our business.
Conducting clinical trials for human drugs and, in certain circumstances, veterinarian trials for animal drugs, and the testing, development and manufacturing and distribution of product candidates are subject to regulation by numerous governmental authorities in the U.S. and other jurisdictions, if we desire to export the resulting products to such other jurisdictions. These regulations govern or affect the testing, manufacture, safety, labeling, storage, record-keeping, approval, distribution, advertising and promotion of product candidates, as well as safe working conditions. Noncompliance with any applicable regulatory requirements can result in suspension or termination of any ongoing clinical trials of a product candidate or refusal of the government to approve a product candidate for commercialization, criminal prosecution and fines, recall or seizure of products, total or partial suspension of production, prohibitions or limitations on the commercial sale of products or refusal to allow the entering into of federal and state supply contracts. The FDA and comparable governmental authorities have the authority to suspend or terminate any ongoing clinical trials of a product candidate or withdraw product approvals that have been previously granted. Even after a product candidate has been approved, the FDA and comparable governmental authorities subject such product to continuing review and regulatory requirements including, for example, requiring the conducting and reporting of the results of certain clinical studies or trials and commitments to voluntarily conduct additional clinical trials. In addition, regulatory approval could impose limitations on the indicated or intended uses for which product candidates may be marketed. With respect to its approval of XIAFLEX for the treatment of adult Dupuytren’s contracture patients with a palpable cord, for example, the FDA has required a REMS program consisting of a communication plan and a medication guide. Currently, there is a substantial amount of congressional and administrative review of the FDA and the regulatory approval process for drug candidates in the U.S. As a result, there may be significant changes made to the regulatory approval process in the U.S. In addition, the regulatory requirements relating to the development, manufacturing, testing, promotion, marketing and distribution of product candidates may change in the U.S. Such changes may increase our costs and adversely affect our operations.
Additionally, failure to comply with, or changes to applicable regulatory requirements may result in a variety of consequences, including the following:
|
|
restrictions on our products or manufacturing processes;
|
|
|
withdrawal of a product from the market;
|
|
|
voluntary or mandatory recall of a product;
|
|
|
suspension or withdrawal of regulatory approvals for a product;
|
|
|
refusal to permit the import or export of our products;
|
|
|
refusal to approve pending applications or supplements to approved applications that we submit;
|
|
|
denial of permission to file an application or supplement in a jurisdiction;
|
|
|
injunctions or the imposition of civil or criminal penalties against us.
|
Our corporate compliance program cannot guarantee that we are in compliance with all potentially applicable laws and regulations and we have incurred and will continue to incur costs relating to compliance with applicable laws and regulations.
We are a small company and we rely heavily on third parties and outside consultants to conduct many important functions. As a biopharmaceutical company, we are subject to a large body of legal and regulatory requirements. In addition, as a publicly traded company we are subject to significant regulations, including the Sarbanes-Oxley Act of 2002 (“SOX”), some of which have only recently been revised or adopted. We cannot assure you that we are or will be in compliance with all potentially applicable laws and regulations. Failure to comply with all potentially applicable laws and regulations could lead to the imposition of fines, cause the value of our common stock to decline, impede our ability to raise capital or list our securities on certain securities exchanges. New rules could make it more difficult or more costly for us to obtain certain types of insurance, including director and officer liability insurance, and we may be forced to accept reduced policy limits and coverage or incur substantially higher costs to obtain the same or similar coverage. The impact of these events could also make it more difficult for us to attract and retain qualified persons to serve on our board of directors, our board committees and as executive officers. We cannot predict or estimate the amount of the additional costs we may incur or the timing of such costs to comply with these rules and regulations.
We may fail to maintain effective internal controls over external financial reporting or such controls may fail or be circumvented.
SOX requires us to report annually on our internal controls over financial reporting, and our business and financial results could be adversely effected if we, or our independent registered public accounting firm, determine that these controls are not effective. In addition, any failure or circumvention of our internal controls and procedures or failure to comply with regulations concerning controls and procedures could have a material effect on our business, results of operation and financial condition. The impact of these events could also make it more difficult for us to attract and retain qualified persons to serve on our board of directors, our board committees and as executive officers.
Risks Related to Growth and Employees
Adverse events or lack of efficacy in clinical trials may force us and/or our partners upon whom we are wholly dependent to stop development of our product candidates or prevent regulatory approval of our product candidates or significant safety issues could arise after regulatory approval of our products, any of which could materially harm our business.
The prescribing information for XIAFLEX for Dupuytren’s contracture made available by Auxilium lists “tendon ruptures or other serious injury to the injected extremity” as a reported serious adverse reaction to XIAFLEX and states that the most frequently reported adverse drug reactions in XIAFLEX clinical trials included swelling of the injected hand, contusion, injection site reaction, injection site hemorrhage, and pain in the treated extremity. The prescribing information notes that adverse reaction rates observed in clinical trials of a drug may not reflect those observed in practice because such trials “are conducted under widely varying conditions.”
Auxilium has reported that the most common adverse events in the Peyronie’s double-blind, placebo-controlled IMPRESS phase III clinical program were hematoma, pain and swelling at the treatment site, with most adverse events being mild or moderate in severity. There were also three serious adverse events of corporal rupture (penile fracture) and three serious adverse events of hematomas related to XIAFLEX reported in IMPRESS I and II.
Adverse events or lack of efficacy may force us to stop development of our product candidates or prevent regulatory approval of our product candidates, which could materially harm our business. In addition, any adverse events or lack of efficacy may force Auxilium to stop development of the products we have licensed to it or prevent regulatory approval of such products, which could materially impair all or a material part of the future revenue we hope to receive from Auxilium. Even if our product candidates receive regulatory approval, new safety issues may be reported and we or our partners may be required to amend the conditions of use for a product.
We and our licensees face competition in our product development and marketing efforts from pharmaceutical and biotechnology companies, universities and other not-for-profit institutions.
We and our licensees face competition in our product development and marketing efforts from entities that have substantially greater research and product development capabilities and greater financial, scientific, marketing and human resources. These entities include pharmaceutical and biotechnology companies, as well as universities and not-for-profit institutions. Our and our licensees’ competitors may succeed in developing products or intellectual property earlier than we or our licensees do, entering into successful collaborations before us or our licensees, obtaining approvals from the FDA or other regulatory agencies for such products before us or our licensees, or developing or marketing products that are more effective than those we or our licensees could develop or market. The success of any one competitor in these or other respects will have a material adverse effect on our business, our ability to receive option payments from Auxilium or our ability to generate revenues from third party arrangements with respect to additional indications for which Auxilium does not exercise its option.
Because of the specialized nature of our business, the termination of relationships with key management, consulting and scientific personnel or the inability to recruit and retain additional personnel could prevent us from developing our technologies, conducting clinical trials and/or obtaining financing.
The competition for qualified personnel in the biotechnology field is intense, and we rely heavily on our ability to attract and contract with qualified independent scientific and medical investigators, and technical and managerial personnel. We face intense competition for qualified individuals from numerous pharmaceutical, biopharmaceutical and biotechnology companies, as well as academic and other research institutions. To the extent we are unable to attract and retain any of these individuals on favorable terms our business may be adversely affected.
If product liability lawsuits are brought against us, we may incur substantial liabilities.
We continue to have product liability exposure for topical product sold by us prior to the sale of our topical business to DFB. In addition, under the Auxilium Agreement, we are obligated to indemnify Auxilium and its affiliates for any harm or losses they suffer relating to any personal injury and other product liability resulting from our development, manufacture or commercialization of any injectable collagenase product. In addition, the clinical testing and, if approved, commercialization of our product candidates involves significant exposure to product liability claims. We have clinical trial and product liability insurance in the aggregate amount of $5.0 million dollars that we believe is adequate in both scope and amount and has been placed with what we believe are reputable insurers. We may not be able to maintain our clinical trial and product liability insurance at an acceptable cost, if at all, and this insurance may not provide adequate coverage against potential claims or losses. If losses from product liability claims exceed our insurance coverage, we may incur substantial liabilities that exceed our financial resources, and our business and results of operations may be harmed. Whether or not we are ultimately successful in product liability litigation, such litigation could consume substantial amounts of our financial and managerial resources, and might result in adverse publicity, all of which could impair our business.
If we are unable to negotiate a new lease for our corporate headquarters or relocate, our existing operations and our operating results could be adversely affected.
As described in this Report under “Item 2 - Description of Property”, we are holding over in our current premises on a month-to-month basis. If we are unable to negotiate a new lease for our current premises or relocate to other premises, our existing operations and operating results could be adversely affected because alternate space may not permit the current laboratory activities with respect to the development of collagenase for use in other indications.
Risks Related to Intellectual Property Rights
If we breach any of the agreements under which we license rights to products or technology from others, we could lose license rights that are critical to our business and our business could be harmed.
We are a party to a number of license agreements by which we have acquired rights to use the intellectual property of third parties that are necessary for us to operate our business. If any of the parties terminates its agreement, whether by its terms or due to our breach, our right to use the party’s intellectual property may negatively affect our licenses to Auxilium or DFB and, in turn, their obligation to make option, milestone, contingent royalty or other payments to us.
Our ability and the ability of our licensors, licensees and collaborators to develop and license products based on our patents may be impaired by the intellectual property of third parties.
Auxilium’s, DFB’s and our commercial success in developing and manufacturing collagenase products based on our patents is dependent on these products not infringing the patents or proprietary rights of third parties. While we currently believe that we, our licensees, licensors and collaborators have freedom to operate in the collagenase market, others may challenge that position in the future. There has been, and we believe that there will continue to be, significant litigation in the pharmaceutical industry regarding patent and other intellectual property rights.
Third parties could bring legal actions against us, our licensees, licensors or collaborators claiming damages and seeking to enjoin clinical testing, manufacturing and marketing of the affected product or products. A third party might request a court to rule that the patents we in-licensed or licensed to others, or those we may in-license in the future, are invalid or unenforceable. In such a case, even if the validity or enforceability of those patents were upheld, a court might hold that the third party’s actions do not infringe the patent we in-license or license to others, which could, in effect, limit the scope of our patent rights and those of our licensees, licensors or collaborators. Our agreements with Auxilium and DFB require us to indemnify them against any claims for infringement based on the use of our technology. If we become involved in any litigation, it could consume a substantial portion of our resources, regardless of the outcome of the litigation. If Auxilium or DFB becomes involved in such litigation, it could also consume a substantial portion of their resources, regardless of the outcome of the litigation, thereby jeopardizing their ability to commercialize candidate products and/or their ability to make option, milestone or royalty payments to us. If any of these actions is successful, in addition to any potential liability for damages, we could be required to obtain a license to permit ourselves, our licensees, licensors or our collaborators to conduct clinical trials, manufacture or market the affected product, in which case we may be required to pay substantial royalties or grant cross-licenses to our patents. However, there can be no assurance that any such license will be available on acceptable terms or at all. Ultimately, we, our licensees, licensors or collaborators could be prevented from commercializing a product, or forced to cease some aspect of their or our business, as a result of patent infringement claims, which could harm our business or right to receive option, milestone and contingent royalty payments.
Risks Related to our Common Stock
Future sales of our common stock could negatively affect our stock price.
If our common stockholders sell substantial amounts of common stock in the public market, or the market perceives that such sales may occur, the market price of our common stock could decline. In addition, we may need to raise additional capital in the future to fund our operations. If we raise additional funds by issuing equity securities, our stock price may decline and our existing stockholders may experience dilution of their interests. Because we historically have not declared dividends, stockholders must rely on an increase in the stock price for any return on their investment in us.
Our stock price has, in the past, been volatile, and the market price of our common stock may drop below the current price.
Our stock price has, at times, been volatile. Currently, our common stock is traded on The Nasdaq Global Market (“Nasdaq”) and is thinly traded.
Market prices for securities of pharmaceutical, biotechnology and specialty pharmaceutical companies have been particularly volatile. Some of the factors that may cause the market price of our common stock to fluctuate include:
|
|
results of our clinical trials;
|
|
|
failure of any product candidates we have licensed to Auxilium or sold to DFB to achieve commercial success;
|
|
|
regulatory developments in the U.S. and foreign countries;
|
|
|
developments or disputes concerning patents or other proprietary rights;
|
|
|
litigation involving us or our general industry, or both;
|
|
|
future sales of our common stock by the estate of our former Chairman and CEO or others;
|
|
|
changes in the structure of healthcare payment systems, including developments in price control legislation;
|
|
|
departure of key personnel;
|
|
|
termination of agreements with our licensees or their sublicensees;
|
|
|
announcements of material events by those companies that are our competitors or perceived to be similar to us;
|
|
|
changes in estimates of our financial results;
|
|
|
investors’ general perception of us;
|
|
|
general economic, industry and market conditions; and
|
|
|
the acquisition by Auxilium of a new product or technology that causes Auxilium to reallocate its priorities away from XIAFLEX.
|
If any of these risks occurs, or continues to occur, it could cause our stock price to fall and may expose us to class action lawsuits that, even if unsuccessful, could be costly to defend and a distraction to management. In addition, purchases of our common stock pursuant to our stock repurchase program may, depending on the timing and volume of such repurchases, result in our stock price being higher than it would be in the absence of such repurchases. If repurchases pursuant to the program are discontinued, our stock price may fall.
We may become subject to stockholder activism efforts that could cause material disruption to our business.
Certain influential institutional investors, hedge funds and other stockholders have taken steps to involve themselves in the governance and strategic direction of certain companies due to governance or strategic related disagreements between such companies and such stockholders. If we become subject to such stockholder activism efforts, it could result in substantial costs and a diversion of management’s attention and resources, which could harm our business and adversely affect the market price of our common stock.
We have no current plan to pay dividends on our common stock and investors may lose the entire amount of their investment.
We have no current plans to pay dividends on our common stock. Therefore, investors will not receive any funds absent a sale of their shares. We cannot assure investors of a positive return on their investment when they sell their shares nor can we assure that investors will not lose the entire amount of their investment.
Our
outstanding options to purchase shares of common stock could have a possible dilutive effect.
As of December 31, 2012, options to purchase 1,182,000 shares of common stock were outstanding. In addition, as of December 31, 2012 a total of 254,098 options were available for grant under our stock option plans. The issuance of common stock upon the exercise of these options could adversely affect the market price of the common stock or result in substantial dilution to our existing stockholders.
If securities analysts do not publish research reports about our business or if they downgrade us or our sector, the price of our common stock could decline.
The trading market for our common stock will depend in part on research reports that industry or financial analysts publish about us or our business. If analysts downgrade us or any of our licensees, or other research analysts downgrade the industry in which we operate or the stock of any of our competitors or licensees, the price of our common stock will probably decline.
Provisions in our certificate of incorporation and bylaws may prevent or frustrate a change in control.
Provisions of our certificate of incorporation and bylaws may discourage, delay or prevent a merger, acquisition or other change in control that stockholders may consider favorable, including transactions in which you might otherwise receive a premium for your shares. These provisions:
|
|
provide for a classified board of directors;
|
|
|
give our Board the ability to designate the terms of and issue new series of preferred stock without stockholder approval, commonly referred to as “blank check” preferred stock, with rights senior to those of our common stock;
|
|
|
limit the ability of the stockholders to call special meetings; and
|
|
|
impose advance notice requirements on stockholders concerning the election of directors and other proposals to be presented at stockholder meetings.
|
In addition, during May 2002, the Board implemented a rights agreement (commonly known as a “Poison Pill”), which effectively discourages or prevents acquisitions of more than 15% of our common stock in transactions (mergers, consolidations, tender offer, etc.) that have not been approved by our Board. The Board amended the Poison Pill in February 2011 to increase the threshold from 15% to 18% and extended the expiration date of the Poison Pill for an additional two years, to May 31, 2014. These provisions could make it more difficult for common stockholders to replace members of the Board. Because our Board is responsible for appointing the members of our management team, these provisions could in turn affect any attempt to replace the current management team.
If our principal stockholders, executive officers and directors choose to act together, they may be able to control our operations, acting in their own best interests and not necessarily those of other stockholders.
As of March 1, 2013 our executive officers, directors and their affiliates, in the aggregate, beneficially owned shares representing approximately 30.6% of our common stock. Beneficial ownership includes shares over which an individual or entity has investment or voting power and includes shares that could be issued upon the exercise of options within 60 days. As a result, if these stockholders were to choose to act together, they may be able to control all matters submitted to our stockholders for approval, as well as our management and affairs. For example, these individuals, if they chose to act together, could control the election of directors and approval of any merger, consolidation or sale of all or substantially all of our assets. This concentration of ownership could have the effect of delaying, deferring or preventing a change in control or impeding a merger or consolidation, takeover or other business combination that could be favorable to other stockholders.
This significant concentration of share ownership may adversely affect the trading price for our common stock because investors often perceive disadvantages in owning stock in companies with controlling stockholders.
