Servier today announced the U.S. Food and Drug Administration (FDA) has approved TIBSOVO® (ivosidenib tablets) for the treatment of patients with isocitrate dehydrogenase 1 (IDH1)-mutated relapsed or refractory (R/R) myelodysplastic syndromes (MDS).

| TIBSOVO is the first and only approved targeted therapy for R/R MDS patients with a susceptible IDH1 mutation Fifth approved indication for TIBSOVO solidifies Servier’s leadership in mutant IDH inhibition BOSTON, Oct. 24, 2023 /PRNewswire/ -- Servier, a leader in oncology committed to bringing the promise of tomorrow to the patients we serve, today announced the U.S. Food and Drug Administration (FDA) has approved TIBSOVO® (ivosidenib tablets) for the treatment of patients with isocitrate dehydrogenase 1 (IDH1)-mutated relapsed or refractory (R/R) myelodysplastic syndromes (MDS). This is the fifth indication for TIBSOVO across IDH1-mutated cancers, and the first and only approved targeted therapy for people diagnosed with R/R MDS within this molecularly defined subset.
“Servier is proud to lead the way in mutant IDH inhibition through continued innovations that support patients living with difficult and hard-to-treat cancers,” said Arjun Prasad, Head of Commercial, Servier Pharmaceuticals. “As the first and only targeted therapy available for patients with IDH1-mutated relapsed or refractory myelodysplastic syndromes, today’s FDA approval for TIBSOVO reinforces our commitment to deliver significant advances in areas of high unmet need and bring the right treatment, to the right patient, at the right time.” The FDA approval of this indication is supported by a pivotal Phase 1, open-label study in IDH1-mutated R/R MDS patients (n=18) where a complete remission (CR) rate of 38.9% and objective response rate (ORR) of 83.3% were documented in patients treated with TIBSOVO. In addition, the median time to CR was 1.9 months (range: 1.0, 5.6). At the time of data cutoff, the median duration of CR had not been reached (range: 1.9, 80.8+*) and the median overall survival was 35.7 months (range: 3.7*, 88.7*). Additionally, of the nine patients who were transfusion dependent with red blood cells or platelets at baseline, 66.7% (n=6) became independent of transfusions during any ≥56-day post-baseline period. Overall, treatment-related adverse events were consistent with the known safety profile of TIBSOVO. “The novel use of targeted therapy across IDH-mutated cancers has become a powerful therapeutic option for patients within this molecularly defined subset,” said Amir Fathi, M.D., hematologist, medical oncologist, and expert in myeloid malignancies. “This new indication in IDH1-mutated relapsed or refractory myelodysplastic syndromes reinforces the importance of mutational testing to inform treatment decisions and potentially improve patient outcomes.” An estimated 16,000 people in the U.S. are diagnosed with MDS each year.1 Approximately 3.6% of MDS patients have an IDH1 mutation,2 which is considered an early “driver” mutation.3 For MDS patients with an IDH1 mutation, the prognosis has often been associated with worse overall outcomes and an increased risk of transformation to AML.2 “This approval for TIBSOVO is welcome news for the MDS community,” said Tracey Iraca, Executive Director, MDS Foundation. “Before today, there were no approved targeted therapies available to relapsed or refractory MDS patients harboring the IDH1-mutation. We want to thank the study participants, their families and caregivers, as well as the researchers at Servier and clinical investigators involved in this study for helping to bring a new treatment option to patients where there has been a significant unmet need.” “An MDS diagnosis is ambiguous. I remember feeling confused trying to make sense of my diagnosis, what having an IDH1-mutation meant, and what options were available for my treatment plan,” said Susan, a patient living with IDH1-mutated MDS.** “The news of an FDA approval for a targeted therapy in IDH-1 mutated MDS has given me a tremendous sense of gratitude and provides hope to patients – like me – who are living with this disease. I want to thank everyone who played a role in this major step forward for the MDS community.” TIBSOVO was granted Breakthrough Therapy designation for the treatment of adult patients with R/R (MDS) with an IDH1 mutation and received Priority Review, which accelerated the review timeline and is granted to applications for medicines that, if approved, would provide significant improvements in the effectiveness or safety of the treatment, diagnosis, or prevention of serious conditions.4 The FDA also approved the Abbott RealTime IDH1 Assay as a companion diagnostic device to select patients for TIBSOVO. * Denotes a censored observation. About the NCT02074839 Clinical Trial5 About TIBSOVO® (ivosidenib tablets) In the U.S., TIBSOVO is approved for the treatment of adults with IDH1-mutant relapsed or refractory AML and in monotherapy or in combination with azacitidine 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, as monotherapy for the treatment of adult patients with IDH1-mutant relapsed or refractory MDS, and for patients with previously treated IDH1-mutated cholangiocarcinoma. Servier has granted CStone a co-exclusive license for the development and an exclusive license agreement for the commercialization of TIBSOVO in Mainland China, Taiwan, Hong Kong, Macao and Singapore.

TIBSOVO IMPORTANT SAFETY INFORMATION AND INDICATION FOR U.S. PATIENTS INDICATIONS TIBSOVO is indicated for patients with a susceptible isocitrate dehydrogenase-1 (IDH1) mutation as detected by an FDA-approved test with: Newly Diagnosed Acute Myeloid Leukemia (AML)
Relapsed or Refractory AML
Relapsed or Refractory Myelodysplastic Syndromes (MDS) For the treatment of adult patients with relapsed or refractory myelodysplastic syndromes Locally Advanced or Metastatic Cholangiocarcinoma For the treatment of adult patients with locally advanced or metastatic cholangiocarcinoma who have been previously treated IMPORTANT SAFETY INFORMATION
WARNINGS AND PRECAUTIONS 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. 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, electrolyte abnormalities, or 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. ADVERSE REACTIONS
