BOSTON, May 5, 2021 /PRNewswire/ -- Servier Pharmaceuticals, a growing leader in oncology committed to bringing the promise of tomorrow to the patients we serve, today announced that the U.S. Food and Drug Administration (FDA) has accepted the company's supplemental New Drug Application (sNDA) for TIBSOVO (ivosidenib tablets) as a potential treatment for patients with previously treated IDH1-mutated cholangiocarcinoma.
The sNDA was granted Priority Review, which accelerates the review time from 10 months to a goal of 6 months from the day of filing acceptance. Priority Review is typically given to drugs that may offer major advances in treatment or may provide a treatment where no adequate therapy exists.
"While today is a significant milestone in our company's history, it is also a beacon of hope for the cholangiocarcinoma patient community," said David K. Lee, CEO, Servier Pharmaceuticals. "As we continue to expand our oncology leadership presence in the U.S. into the solid tumor space, we remain committed to addressing the critical unmet needs of patients with difficult-to-treat cancers including cholangiocarcinoma."
The sNDA acceptance is supported by data from the ClarIDHy study, the first and only randomized Phase 3 trial for previously treated IDH1-mutated cholangiocarcinoma. An encore presentation of the data will be presented at the American Society of Clinical Oncology (ASCO) Annual Meeting on June 4-8, 2021.
"Currently, there are no approved systemic therapies for IDH1-mutated cholangiocarcinoma and limited chemotherapy options are available for patients with advanced disease," said Susan Pandya, M.D., Vice President, Clinical Development, Head of Cancer Metabolism Global Development, Servier Pharmaceuticals. "The FDA's Priority Review is a major milestone for patients. I'd like to acknowledge and thank all the patients, their families and the investigators and research teams who took part in the ClarIDHy study."
TIBSOVO (ivosidenib tablets) is currently approved in the U.S. as monotherapy for the treatment of adults with IDH1-mutant relapsed or refractory acute myeloid leukemia (AML) and for adults with newly diagnosed IDH1-mutant AML who are ≥75 years old or who have comorbidities that preclude the use of intensive induction chemotherapy.
In an effort to meet more patient needs than ever before, Servier Pharmaceuticals has grown by nearly 20% in the past two years. The company will continue to grow its oncology portfolio through new and existing research and development collaborations, potential acquisitions and a new lab opening in 2022.
Cholangiocarcinoma is a rare, aggressive cancer of the bile ducts within and outside of the liver. IDH1 mutations occur in approximately 13% of cholangiocarcinoma cases and are not associated with prognosis. There are no approved systemic therapies for IDH1-mutated cholangiocarcinoma and limited chemotherapy options are available in the advanced setting. Gemcitabine-based chemotherapy is often recommended for newly diagnosed advanced or metastatic disease.
About TIBSOVO® (ivosidenib tablets)
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 ≥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-HT3 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 AML 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.
In patients with newly diagnosed AML, the most frequently reported Grade ≥3 adverse reactions (≥5%) were fatigue (14%), differentiation syndrome (11%), electrocardiogram QT prolonged (11%), diarrhea (7%), nausea (7%), and leukocytosis (7%). Serious adverse reactions (≥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 adverse reactions (≥5%) were differentiation syndrome (13%), electrocardiogram QT prolonged (10%), dyspnea (9%), leukocytosis (8%), and tumor lysis syndrome (6%). Serious adverse reactions (≥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.
LACTATION 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.
