Agios Announces the Randomized Phase 3 ClarIDHy Trial of TIBSOVO ® (ivosidenib)
Achieved its Primary Endpoint in Previously Treated IDH1 Mutant Cholangiocarcinoma
TIBSOVO ® Demonstrated a Statistically Significant Improvement in Progression-Free Survival Compared to Placebo
Safety Profile Consistent with Published Phase 1 Data in Patients with IDH1 Mutant Solid Tumors
Supplemental New Drug Application on Track for Submission by End of 2019
CAMBRIDGE, Mass., May 15, 2019 Agios Pharmaceuticals, Inc. (NASDAQ:AGIO), a leader in the field of cellular metabolism to treat cancer and rare genetic diseases, today announced that the global Phase 3 ClarIDHy trial of TIBSOVO ® (ivosidenib) in previously treated cholangiocarcinoma patients with an isocitrate dehydrogenase 1 (IDH1) mutation met its primary endpoint. Treatment with TIBSOVO ® demonstrated a statistically significant improvement in progression-free survival (PFS) by independent radiology review compared with patients who received placebo. The safety profile observed in the study was consistent with previously published data.
A full analysis of the ClarIDHy trial will be submitted for presentation at the European Society for Medical Oncology Congress taking place in Barcelona, Spain from September 27-October 1, 2019. The company plans to submit a supplemental new drug application for TIBSOVO ® in previously treated IDH1 mutant cholangiocarcinoma by the end of 2019.
Advanced cholangiocarcinoma is a life-threatening disease with no currently approved treatment options, said Chris Bowden, M.D., chief medical officer at Agios. The data from the ClarIDHy Phase 3 trial demonstrate the clinically significant benefit of TIBSOVO ® in patients with this challenging disease who harbor the IDH1 mutation. We are committed to working with regulators to bring this potential treatment option to patients as quickly as possible. We thank the patients and physicians who participated in the ClarIDHy study, without whom this important advancement would not be possible.
ClarIDHy Phase 3 Trial
The ClarIDHy trial is a global, randomized Phase 3 trial in previously treated IDH1 mutant cholangiocarcinoma patients who have documented disease progression following one or two systemic therapies in the advanced setting. As of the January 31, 2019 data cutoff, 185 patients were randomized.
Patients were randomized 2:1 to receive either single-agent TIBSOVO ® 500 mg once daily or placebo with crossover to TIBSOVO ® permitted at the time of documented radiographic progression per RECIST 1.1.
The primary endpoint of the trial is PFS as evaluated by independent radiology review with secondary endpoints including investigator evaluated PFS, safety and tolerability, overall response rate, overall survival, duration of response, PK/PD and quality of life assessments.
The study was designed with 96% power to detect a hazard ratio of 0.5 for PFS (TIBSOVO ® vs. placebo), with a one-sided alpha of 0.025.
Thermo Fisher Scientific is providing next-generation sequencing to detect IDH1 mutations for all tumor samples as inclusion criteria for enrollment in the study and will develop and commercialize the validated companion diagnostic.
TIBSOVO ® is not approved in any country for the treatment of patients with advanced cholangiocarcinoma.
About TIBSOVO ® (ivosidenib)
TIBSOVO ® is indicated for the treatment of acute myeloid leukemia (AML) with a susceptible isocitrate dehydrogenase-1 (IDH1) mutation as detected by an FDA-approved test in:
Adult patients with newly-diagnosed AML who are ³ 75 years old or who have comorbidities that preclude use of intensive induction chemotherapy.
Adult patients with relapsed or refractory AML.
IMPORTANT SAFETY INFORMATION
WARNING: DIFFERENTIATION SYNDROME
Patients treated with TIBSOVO ® have experienced symptoms of differentiation syndrome, which can be fatal if not treated. Symptoms may include fever, dyspnea, hypoxia, pulmonary infiltrates, pleural or pericardial effusions, rapid weight gain or peripheral edema, hypotension, and hepatic, renal, or multi-organ dysfunction. If differentiation syndrome is suspected, initiate corticosteroid therapy and hemodynamic monitoring until symptom resolution.
WARNINGS AND PRECAUTIONS
Differentiation Syndrome: See Boxed WARNING. In the clinical trial, 25% (7/28) of patients with newly diagnosed AML and 19% (34/179) of patients with relapsed or refractory AML treated with TIBSOVO ® experienced differentiation syndrome. Differentiation syndrome is associated with rapid proliferation and differentiation of myeloid cells and may be life-threatening or fatal if not treated. Symptoms of differentiation syndrome in patients treated with TIBSOVO ® included noninfectious leukocytosis, peripheral edema, pyrexia, dyspnea, pleural effusion, hypotension, hypoxia, pulmonary edema, pneumonitis, pericardial effusion, rash, fluid overload, tumor lysis syndrome, and creatinine increased. Of the 7 patients with newly diagnosed AML who experienced differentiation syndrome, 6 (86%) patients recovered. Of the 34 patients with relapsed or refractory AML who experienced differentiation syndrome, 27 (79%) patients recovered after treatment or after dose interruption of TIBSOVO ® . Differentiation syndrome occurred as early as 1 day and up to 3 months after TIBSOVO ® initiation and has been observed with or without concomitant leukocytosis.
If differentiation syndrome is suspected, initiate dexamethasone 10 mg IV every 12 hours (or an equivalent dose of an alternative oral or IV corticosteroid) and hemodynamic monitoring until improvement. If concomitant noninfectious leukocytosis is observed, initiate treatment with hydroxyurea or leukapheresis, as clinically indicated. Taper corticosteroids and hydroxyurea after resolution of symptoms and administer corticosteroids for a minimum of 3 days. Symptoms of differentiation syndrome may recur with premature discontinuation of corticosteroid and/or hydroxyurea treatment. If severe signs and/or symptoms persist for more than 48 hours after initiation of corticosteroids, interrupt TIBSOVO ® until signs and symptoms are no longer severe .
QTc Interval Prolongation: Patients treated with TIBSOVO ® can develop QT (QTc) prolongation and ventricular arrhythmias. One patient developed ventricular fibrillation attributed to TIBSOVO ® . Concomitant use of TIBSOVO ® with drugs known to prolong the QTc interval (e.g., anti-arrhythmic medicines, fluoroquinolones, triazole anti-fungals, 5-HT 3 receptor antagonists) and CYP3A4 inhibitors may increase the risk of QTc interval prolongation. Conduct monitoring of electrocardiograms (ECGs) and electrolytes. In patients with congenital long QTc syndrome, congestive heart failure, or electrolyte abnormalities, or in those who are taking medications known to prolong the QTc interval, more frequent monitoring may be necessary.
Interrupt TIBSOVO ® if QTc increases to greater than 480 msec and less than 500 msec. Interrupt and reduce TIBSOVO ® if QTc increases to greater than 500 msec. Permanently discontinue TIBSOVO ® in patients who develop QTc interval prolongation with signs or symptoms of life-threatening arrhythmia.
Guillain-Barré Syndrome: Guillain-Barré syndrome occurred in <1% (2/258) of patients treated with TIBSOVO ® in the clinical study. Monitor patients taking TIBSOVO ® for onset of new signs or symptoms of motor and/or sensory neuropathy such as unilateral or bilateral weakness, sensory alterations, paresthesias, or difficulty breathing. Permanently discontinue TIBSOVO ® in patients who are diagnosed with Guillain-Barré syndrome.
The most common adverse reactions including laboratory abnormalities ( ³ 20%) were hemoglobin decreased (60%), fatigue (43%), arthralgia (39%), calcium decreased (39%), sodium decreased (39%), leukocytosis (38%), diarrhea (37%), magnesium decreased (36%), edema (34%), nausea (33%), dyspnea (32%), uric acid increased (32%), potassium decreased (32%), alkaline phosphatase increased (30%), mucositis (28%), aspartate aminotransferase increased (27%), phosphatase decreased (25%), electrocardiogram QT prolonged (24%), rash (24%), creatinine increased (24%), cough (23%), decreased appetite (22%), myalgia (21%), constipation (20%), and pyrexia (20%).
In patients with newly diagnosed AML, the most frequently reported Grade ³ 3 adverse reactions ( ³ 5%) were fatigue (14%), differentiation syndrome (11%), electrocardiogram QT prolonged (11%), diarrhea (7%), nausea (7%), and leukocytosis (7%). Serious adverse reactions ( ³ 5%) were differentiation syndrome (18%), electrocardiogram QT prolonged (7%), and fatigue (7%). There was one case of posterior reversible encephalopathy syndrome (PRES).
In patients with relapsed or refractory AML, the most frequently reported Grade ³ 3 adverse reactions ( ³ 5%) were differentiation syndrome (13%), electrocardiogram QT prolonged (10%), dyspnea (9%), leukocytosis (8%), and tumor lysis syndrome (6%). Serious adverse reactions ( ³ 5%) were differentiation syndrome (10%), leukocytosis (10%), and electrocardiogram QT prolonged (7%). There was one case of progressive multifocal leukoencephalopathy (PML).
Strong or Moderate CYP3A4 Inhibitors: Reduce TIBSOVO ® dose with strong CYP3A4 inhibitors. Monitor patients for increased risk of QTc interval prolongation.
Strong CYP3A4 Inducers: Avoid concomitant use with TIBSOVO ® .
Sensitive CYP3A4 Substrates: Avoid concomitant use with TIBSOVO ® .
QTc Prolonging Drugs: Avoid concomitant use with TIBSOVO ® . If co-administration is unavoidable, monitor patients for increased risk of QTc interval prolongation.
Because many drugs are excreted in human milk and because of the potential for adverse reactions in breastfed children, advise women not to breastfeed during treatment with TIBSOVO ® and for at least 1 month after the last dose.
Please see full Prescribing Information, including Boxed WARNING.
Cholangiocarcinoma (CC) is a rare cancer of the bile ducts within and outside of the liver. Cases that occur within the liver are known as intrahepatic cholangiocarcinoma (IHCC) and those that occur outside the liver are considered extrahepatic. Mutations in IDH1 occur in up to 20% of IHCC cases. Current treatment options for localized disease include surgery, radiation and/or other ablative treatments. There are no approved systemic therapies for cholangiocarcinoma and limited chemotherapy options are available in the advanced setting. Gemcitabine-based chemotherapy is often recommended for newly diagnosed metastatic disease.
