On December 11, 2021 Servier, a growing leader in oncology committed to bringing the promise of tomorrow to the patients we serve, reported Phase 3 data demonstrating that TIBSOVO (ivosidenib tablets) in combination with the chemotherapy azacitidine significantly improved event-free survival (EFS) and overall survival (OS) compared to azacitidine plus placebo in adults with previously untreated IDH1-mutated acute myeloid leukemia (AML) who are not candidates for intensive chemotherapy (Press release, Servier, DEC 11, 2021, View Source [SID1234596887]). These data from the global AGILE study will be presented in an oral session on Monday, December 13, 2021 from 2:45 – 4:15 PM ET, Abstract #697 and featured in the official press program during the 63rd American Society of Hematology (ASH) (Free ASH Whitepaper) Annual Meeting and Exposition.

Treatment with TIBSOVO in combination with azacitidine demonstrated a statistically significant improvement in 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 OS (HR = 0.44 [95% CI 0.27, 0.73]; 1-sided P = 0.0005), with a median OS of 24.0 months in the ivosidenib + azacitidine arm vs 7.9 months in the placebo + azacitidine arm.

"These significant findings from the AGILE Phase 3 study for TIBSOVO bolster our growing body of evidence supporting the rationale to target IDH1 mutations early in blood cancers like acute myeloid leukemia," said Susan Pandya, M.D., Vice President Clinical Development & Head of Cancer Metabolism Global Development Oncology & Immuno-Oncology, Servier Pharmaceuticals. "Up to 10 percent of patients with AML have mutations in the IDH1 enzyme, and current treatment options are limited, especially for those who are newly diagnosed and are not eligible for intensive chemotherapy."

Additional Study Results
Investigators reported on results of key secondary endpoints of the AGILE trial including:

Complete remission (CR) rate was 47.2% (n=34/72) for TIBSOVO in combination with azacitidine vs. 14.9% (n=11/74) for placebo plus azacitidine (p < 0.0001).
CR + complete remission with partial hematologic recovery rate (CR + CRh rate) was 52.8% (n=38/72) for TIBSOVO in combination with azacitidine vs. 17.6% (n=13/74) for placebo plus azacitidine (p < 0.0001).
Objective response rate (ORR) was 62.5% (n=45/72) for TIBSOVO in combination with azacitidine vs. 18.9% (n=14/74) for placebo plus azacitidine (p < 0.0001).
"We are excited about the potential to bring a new treatment option to patients with previously untreated IDH1-mutated AML. This further extends the significant clinical benefit for patients with acute myeloid leukemia and IDH1 mutations," said Patrick Therasse, M.D., Ph.D., Vice President, Head of Late Stage and Life Cycle Management in Oncology and Immuno-Oncology Therapeutic Area, Servier Group.

Acute myeloid leukemia is a rapidly progressing type of cancer, and the prognosis is often poor," said Stephane De Botton, M.D. Ph.D., Principle Investigator and Head of Multidisciplinary Hematology Committee at the Institut Gustave Roussy, Villejuif, France. "Our goal with treatment is to prolong overall survival, and the impressive clinical benefit following treatment with TIBSOVO in combination with azacitidine is incredibly promising for these patients with previously untreated IDH1-mutated acute myeloid leukemia."

Common all-grade adverse events (AEs) occurring in more than 20 percent of patients receiving TIBSOVO in combination with azacitidine vs. placebo plus azacitidine were nausea (42.3% vs. 38.4%), vomiting (40.8% vs 26.0%), diarrhea (35.2% vs 35.6%), pyrexia (33.8% vs 39.7%), anemia (31.0% vs 28.8%), febrile neutropenia (28.2% vs 34.2%), thrombocytopenia (28.2% vs 20.5%), neutropenia (28.2% vs 16.4%), constipation (26.8% vs 52.1%) and pneumonia (23.9% vs 31.5%).

The AGILE study has halted further enrollment due to compelling efficacy data for TIBSOVO.

Servier is in discussions with regulatory health authorities regarding submissions to expand the currently approved indications for TIBSOVO.

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.

About 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.

Other key secondary endpoints included complete remission rate (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 Acute Myeloid Leukemia
Acute myeloid leukemia (AML) is a cancer of the blood and bone marrow marked by rapid disease progression and is the most common acute leukemia affecting adults with approximately 20,000 new cases in the U.S., and 43,000 cases in Europe each year3,4. The majority of patients with AML eventually relapse. Relapsed or refractory AML has a poor prognosis5. The five-year survival rate is approximately 27%3. For 6 to 10 percent of AML patients, the mutated IDH1 enzyme blocks normal blood stem cell differentiation, contributing to the genesis of acute leukemia6.
