RADNOR, Pa.--(BUSINESS WIRE)-- Marinus Pharmaceuticals, Inc. (Nasdaq: MRNS), a pharmaceutical company dedicated to the development of innovative therapeutics to treat rare seizure disorders, today provided an update on its clinical and regulatory development activities and reported its financial results for the fourth quarter and fiscal year ended December 31, 2020.
“Although 2020 was extremely challenging for so many, we finished the year achieving several important milestones, which has provided momentum into 2021,” said Scott Braunstein, M.D., Chief Executive Officer of Marinus Pharmaceuticals. “We remain on track to submit a new drug application to the FDA for use of ganaxolone in CDKL5 Deficiency Disorder, continue active enrollment in our Phase 3 RSE trial, while advancing and expanding our oral programs. In the second half of 2021 our attention will continue to be focused on enrolling our Phase 3 trials in RSE and TSC, advancing our commercialization preparations for ganaxolone’s potential launch in CDKL5 deficiency disorder, and expanding our novel formulation development work. We are also looking to expand our oral and IV franchises into new target therapeutic indications with significant unmet medical need and a strong scientific rationale for the use of ganaxolone.”
“Based on the progress to date, as well as our analysis of all prior studies in a number of epilepsy indications, we believe that the oral formulation of ganaxolone has the potential to become an important drug in a variety of rare, pediatric seizure disorders, a tremendous complement to our expanding IV franchise,” Dr. Braunstein said.
Dr. Braunstein added, “In December, we raised $70 million, ending the year with $140 million of cash on hand, which provides financial support for our ongoing clinical trials, commercial planning and portfolio development. We continue to add talent throughout the organization, including in our commercial, clinical, legal, regulatory, and operations areas. Our focus remains on realizing ganaxolone’s potential to help those suffering from rare seizure disorders.”
Pipeline Update:
PCDH19 Related Epilepsy (PCDH19-RE)
| · | Top line data from PCDH19 Phase 2 Violet Study proof-of-concept trial (n=21) showed an encouraging efficacy signal, consistent with the Phase 3 Marigold Study (CDKL5) reported in September | |
| · | Ganaxolone showed an absolute 61.5% improvement in seizure frequency compared to 24.0% in the placebo arm (p=0.17) | |
| · | Ganaxolone was generally well tolerated, with one patient discontinuing in the ganaxolone arm due to a serious adverse event, psychogenic nonepileptic seizures, judged by the investigator to be ganaxolone-related | |
| · | There was no efficacy signal for the allopregnanolone-sulfate biomarker | |
| · | The company plans to present the findings from the Violet Study at a scientific meeting later this year, and also intends to submit the results for publication in a medical journal |
"These findings are very encouraging for those living with PCDH19-related epilepsy, in which many patients continue to experience clusters of seizures that often require inpatient hospitalization. Reducing seizure frequency for this patient population is clinically meaningful," said Joseph Sullivan, M.D., Professor of Neurology & Pediatrics, Director, UCSF Benioff Children’s Hospital Pediatric Epilepsy Center of Excellence.
Tuberous Sclerosis Complex (TSC)
| · | The company’s interim evaluation of efficacy and safety from the CALM Study in TSC supports plan to move to a Phase 3 trial in Q3 2021 | |
| · | Full top-line data (trial enrollment approximately 25 patients) is expected in Q3 2021 | |
| · | The Phase 2 trial protocol was designed with a four-week baseline phase, followed by a 12-week treatment phase during which patients will receive up to 600mg of ganaxolone (oral liquid suspension) three times a day. Patients who meet eligibility criteria may continue ganaxolone treatment during a planned 24-week extension phase |
| · | An end of Phase 2 meeting with the FDA is targeted for Q2 2021 and a meeting with the European Medicines Agency (EMA) is targeted for Q3 2021 | |
| · | Enrollment of the first patient in double blind, placebo controlled, global Phase 3 trial is anticipated in Q4 2021 |
CDKL5 Deficiency Disorder (CDD)
| · | A pre-NDA meeting with the FDA is scheduled for the end of the first quarter of 2021 to gain FDA’s alignment on the proposed format and content of the NDA, which is on track to be submitted by mid-year | |
| · | The company presented additional details of the Phase 3 Marigold Study at AES 2020 in December, including: |
| · | An analysis of data showing a consistent efficacy signal across multiple subgroups, including a 36.7% estimated difference in major motor seizure frequency relative to placebo in U.S. patients (n=41) | |
| · | Preliminary analysis of data from the open-label extension provided supportive data on the durability of ganaxolone efficacy, demonstrating a 52.7% median reduction in major motor seizure frequency in patients who had completed approximately one year of therapy | |
| · | Higher average ganaxolone plasma concentrations correlated with improvements in seizure frequency. Data were also presented that support three times a day dosing |
| · | Marinus initiated an expanded access program (EAP) in the U.S. for patients with CDD | |
| · | The Phase 3 Marigold Study was the first double-blind, placebo-controlled trial to demonstrate efficacy in CDD and the first Phase 3 trial to examine three times a day dosing of ganaxolone in pediatric patients | |
| · | The company remains on track for an EMA pre-marketing authorization application (MAA) meeting to support a MAA submission targeted for the end of Q3 2021 | |
| · | Discussions continue for European commercial partner, targeting a completion this summer |
Refractory Status Epilepticus (RSE)
| · | Several patients have been enrolled in the RAISE trial for the treatment of RSE, with site activations, screening and enrollment ongoing | |
| · | Company expects to have vast majority of sites for the Phase 3 RAISE trial open by the end of Q2, despite the headwinds at hospital intensive care units created by COVID-19 | |
| · | Topline data expected in 1H 2022 |
| · | The RAISE trial is a randomized, double-blind, placebo-controlled trial that will evaluate the efficacy and safety of IV ganaxolone in patients with RSE who have failed benzodiazepines and two or more second line intravenous antiepileptic drugs (AEDs) | |
| · | The trial will examine the proportion of participants with RSE who experience seizure cessation within 30 minutes of initiation of IV ganaxolone as well as the rate of progression to IV anesthesia within 36 hours | |
| · | Ganaxolone development for RSE is being funded, in part, by the Biomedical Advanced Research and Development Authority (BARDA), part of the Office of the Assistant Secretary for Preparedness and Response at the U.S. Department of Health and Human Services, under contract number 75A50120C00159 | |
| · | A Phase 2 trial of adjuvant use of ganaxolone in established status epilepticus (ESE) is planned to begin enrollment in Q1 2022; trial will investigate early intervention in the treatment of status epilepticus, targeting patients who present to the emergency room with convulsive SE, and who have been treated with and failed first-line treatment with benzodiazepines | |
| · | Planning continues for a separate RSE trial to be conducted in Europe. Marinus intends to meet with the EMA to discuss trial design this quarter; trial planned to commence in the first half 2022 | |
| · | Marinus continues to field requests from investigators for IV ganaxolone for patients with super refractory status epilepticus (SRSE) under an Emergency Investigational New Drug application (eIND) |
Corporate Update
| · | Company raised $70 million of gross proceeds in an underwritten public offering of 5 million shares of common stock, before deducting the underwriting discounts and commissions and other estimated offering expenses payable by Marinus | |
| · | Continued growing commercial team commensurate with planning for a mid-2021 NDA submission of ganaxolone in the treatment of seizure disorders in patients with CDD and a mid year 2022 launch, if approved |
CFO Transition
Edward F. Smith, Chief Financial Officer, will be leaving the company to pursue other career opportunities. Mr. Smith has been with the company since 2013, and during his tenure has driven the finance, accounting, information technology, and program management functions, as Marinus sharpened its focus onto its core rare epilepsy franchise. The company has appointed Steven Pfanstiel, who brings 16 years of J&J experience in various financial reporting and business support roles, and most recently at LifeScan Inc., a former J&J business unit focused on blood glucose monitoring, where he served as Vice President, Finance. Mr. Pfanstiel’s effective start date is April 12, 2021.
Financial Update
At December 31, 2020, the company had cash, cash equivalents and investments of $140.0 million, compared to $91.7 million at December 31, 2019. The company believes its cash and cash equivalents as of December 31, 2020 will enable it to fund the company’s current scale of operating expenses and capital expenditures into 2Q 2022. Marinus projects spend in the range of $18 to $20 million per quarter in 2021, offset by approximately $2 to $3 million per quarter from BARDA in 2021. This spend could increase in 3Q with the initiation of the TSC trial and ongoing expenses associated with the RAISE trial.
Marinus recognized $1.7 million in federal contract revenue in the year ended December 31, 2020 as a result of the BARDA contract the company entered into in September 2020. No federal contract revenue was recognized in the year ending December 31, 2019.
Research and development expenses increased to $13.0 million and $51.1 million for the three and twelve months ended December 31, 2020, respectively, as compared to $12.5 million and $43.0 million for the same periods in the prior year. The increase was due primarily to Marinus’ ongoing enrollment in the company’s Phase 3 Marigold Study, which top-line data were announced during the third quarter of 2020, and increased drug development activity, including preclinical studies and manufacturing activities in preparation for a potential NDA filing for ganaxolone in CDD and the recently initiated RAISE trial.
General and administrative expenses increased to $6 million and $18.6 million for the three and twelve months ended December 31, 2020, respectively, compared to $3.0 million and $11.5 million for the same periods in the prior year. The primary drivers of the increase were increased legal and consulting fees of $2.7 million and $1.5 million related to increased headcount as we scale up the company’s operations and prepare for potential commercialization, and noncash stock-based compensation of $1.6 million.
The company reported net losses of $17.5 million and $67.5 million for the three and twelve months ended December 31, 2020, respectively, compared to $15.4 million and $54.1 million in the same period a year ago. Cash used in operating activities increased to $60.9 million for the year ended December 31, 2020 compared to $48.6 million for the same period a year ago.
Readers are referred to, and encouraged to read in its entirety, the company’s Annual Report on Form 10-K for the year ended December 31, 2020, to be filed with the Securities and Exchange Commission, which includes further detail on the above-referenced matters and the company’s business plans, operations, financial condition and results of operations.
