Servier Announces FDA Filing Acceptance and Priority Review for TIBSOVO® (ivosidenib tablets) in Combination with Azacitidine for Patients with Previously Untreated IDH1-mutated Acute Myeloid Leukemia
TIBSOVO is the first therapy targeting cancer metabolism to demonstrate improved event-free survival and overall survival in combination with azacitidine compared to azacitidine plus placebo
BOSTON, March 7, 2022 /PRNewswire/ -- Servier a 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 untreated IDH1-mutated acute myeloid leukemia (AML). The sNDA was granted Priority Review, which accelerates the review and shortens the review time goal from 10 months to 6 months. Priority Review is typically given to drugs that may offer major advances in treatment or may provide a treatment where no adequate therapy exists.
"On the heels of our recent FDA approval of TIBSOVO in cholangiocarcinoma, we are pleased with this important step forward in the agency's consideration to expand its current indication to include the treatment of patients with previously untreated IDH1-mutated acute myeloid leukemia," said David K. Lee, Chief Executive Officer, Servier Pharmaceuticals. "We are thrilled with the positive momentum of this program as we continue to grow our leadership in oncology and deliver more life-changing medicines to patients living with difficult-to-treat cancers."
The sNDA acceptance is supported by results from the AGILE study, a global, Phase 3 trial in patients with previously untreated IDH1-mutated AML, which were presented at the 2021 American Society of Hematology Annual Meeting and Exposition. The data demonstrated that treatment with TIBSOVO in combination with azacitidine significantly improved event-free survival (EFS) (hazard ratio [HR] = 0.33, 95% CI 0.16, 0.69, 1-sided P = 0.0011 1,2). In addition, the combination of TIBSOVO with azacitidine showed a statistically significant improvement in overall survival (OS) (HR = 0.44 [95% CI 0.27, 0.73]; 1-sided P = 0.0005), with a median OS of 24.0 months.
"TIBSOVO is the first therapy targeting cancer metabolism to demonstrate improved event-free survival and overall survival in combination with azacitidine in patients with previously untreated IDH1-mutated AML," said Susan Pandya, M.D., Vice President Clinical Development and Head of Cancer Metabolism Global Development Oncology & Immuno-Oncology, Servier Pharmaceuticals. "With this FDA acceptance for Priority Review, we are closer to offering this critical treatment option to patients in the U.S. and we look forward to engaging with regulatory agencies around the world."
TIBSOVO[*] 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. Recently, TIBSOVO was approved as a first and only targeted therapy for patients with previously treated IDH1-mutated cholangiocarcinoma.
In an effort to bring innovative treatment options to patients living with difficult-to-treat cancers, Servier has made oncology a priority globally, and allocates more than 50% of its research and development budget to cancer research. With more than 21 oncology assets at varying stages of clinical development, and 20 research projects ongoing, Servier is committed to finding solutions that address patient needs across the entire spectrum of disease and in a variety of tumor types.
About the NCT03173248 AGILE Phase 3 AML Trial
The AGILE trial is a global, Phase 3, multicenter, double-blind, randomized, placebo-controlled clinical trial designed to evaluate the efficacy and safety of TIBSOVO in combination with azacitidine compared with placebo in combination with azacitidine, in adults with previously untreated IDH1-mutated acute myeloid leukemia (AML) who are not candidates for intensive chemotherapy (≥75 years old or who have comorbidities that preclude the use of intensive induction chemotherapy). The study's primary endpoint is EFS, defined as the time from randomization until treatment failure, relapse from remission, or death from any cause, whichever occurs first. Treatment failure is defined as failure to achieve complete remission (CR) by Week 24.
Key secondary endpoints included CR rate, defined as the proportion of participants who achieve a CR; overall survival (OS), defined as the time from date of randomization to the date of death due to any cause; CR and complete remission with partial hematologic recovery (CRh) rate, defined as the proportion of participants who achieve a CR or CRh; and objective response rate (ORR), defined as the rate of CR, CR with incomplete hematologic recovery (CRi) (including CR with incomplete platelet recovery [CRp]), partial remission (PR), and morphologic leukemia-free state (MLFS).

About TIBSOVO (ivosidenib tablets)
Acute Myeloid Leukemia (AML)
Locally Advanced or Metastatic Cholangiocarcinoma
IMPORTANT SAFETY INFORMATION
WARNINGS AND PRECAUTIONS
Differentiation Syndrome in AML: 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. 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 can develop in patients treated with TIBSOVO. 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.
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.
