Data at ASH 2023 Underscores Servier Leadership in Hard-to-Treat Hematologic Malignancies

Data in acute myeloid leukemia shows clinical benefits of TIBSOVO®+azacitidine  as the standard of care in front-line IDH1-mutated AML

Data in acute lymphoblastic leukemia furthers Servier’s commitment to patients with ALL across pediatric, adolescent/young adult and adult populations

BOSTON, December 5, 2023 –Servier, a leader in oncology committed to bringing the promise of tomorrow to the patients we serve, will present data in acute myeloid leukemia (AML) and acute lymphoblastic leukemia (ALL) at the 65th American Society of Hematology (ASH) Annual Meeting and Exposition in San Diego from December 9-12, 2023. The latest data underscores Servier’s commitment to uncover insights that can lead to improved outcomes for patients through advancing scientific research and analyzing real-world evidence for patients with difficult and hard-to-treat cancers.

“On the heels of our recent FDA approval for TIBSOVO® (ivosidenib tablets) in relapsed/refractory IDH1-mutated myelodysplastic syndromes (MDS), we are coming to ASH with another proof point on our industry leadership in mutant IDH inhibition and bringing transformational treatments to people faced with high unmet needs in oncology, including blood cancers,” said David K. Lee, CEO, Servier Pharmaceuticals. “Through our focus on precision medicine, we are also advocates of molecular testing. As turn-around times get faster, and data shows that waiting to treat in some patient populations until molecular profiling is complete does not result in a negative prognostic outcome, we hope to provide comprehensive and meaningful treatment information that may help to improve outcomes.”

Servier data being presented at ASH are listed below and are available online on the ASH website here.

  • A large retrospective study comparing two first-line combination regimens for newly diagnosed patients with IDH1-mutated acute myeloid leukemia (mIDH1 AML), ineligible for intensive chemotherapy, to gain insight into real-world treatment patterns, effectiveness and safety
  • A global longitudinal study of patients with AML, with or without mIDH1 disease, who received first-line intensive chemotherapy to gain insight into treatment patterns and clinical outcomes in the real-world setting
  • An analysis of the Phase 3 AGILE study in patients with newly diagnosed AML, who are not eligible for intensive induction chemotherapy, using next-generation sequencing to determine measurable residual disease (MRD), a negative prognostic marker, among patients who had a best overall response to treatment in the study
  • A retrospective study in adolescents and young adults with acute lymphoblastic leukemia, to gain real-world insight into treatment approaches for this population across diverse cancer care settings

“Looking to the future, improving patient outcomes is going to be a collaborative effort across the industry, academia and the community. Servier is proud to serve as a bridge across these stakeholders in our goal of improving patient outcomes,” said Becky Martin, PhD, Chief of Medical, Servier Pharmaceuticals. “By delving deeper into data and experiences, we can identify key factors that, when addressed, contribute to a more effective and tailored healthcare strategy, ultimately benefiting the patients we serve.”

Among Servier data being presented is real-world evidence comparing Tibsovo in combination with hypomethylating agents (HMA) versus venetoclax in combination with hypomethylating agents in patients with newly diagnosed AML (intensive chemotherapy induction ineligible – ICIE) and a susceptible IDH1 mutation. In the analysis, Tibsovo+HMA elicited a higher complete response (CR) rate versus venetoclax+HMA at 42.9% vs. 26.7% (p=0.007). 6-month event-free survival also favored Tibsovo+HMA at 56.0% vs. 39.6% (p=0.044), as well as 11.5% of patients on Tibsovo+HMA achieving bridge to transplant versus 5.0% on a venetoclax+HMA regimen (p=0.066). The full analysis will be presented on Monday, December 11 at 5:30 p.m. PST.

Additional data being presented at ASH includes molecular measurable residual disease (MRD) in ICIE patients with newly diagnosed mIDH1 AML treated with Tibsovo+azacitidine, further bolstering the clinical profile of Tibsovo in the front-line setting, as well as real-world analyses examining treatment patterns in both ALL and AML.

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)

  • In combination with azacitidine or as monotherapy for the treatment of newly diagnosed AML in adults 75 years or older, or who have comorbidities that preclude use of intensive induction chemotherapy

Relapsed or Refractory AML

  • For the treatment of adult patients with 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


Patients treated with TIBSOVO have experienced symptoms of differentiation syndrome, which can be fatal. 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.

Differentiation Syndrome in AML and MDS: 
Differentiation syndrome is associated with rapid proliferation and differentiation of myeloid cells and may be life-threatening or fatal.

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.


  • In patients with AML, the most common adverse reactions including laboratory abnormalities (≥25%) are leukocytes decreased, diarrhea, hemoglobin decreased, platelets decreased, glucose increased, fatigue, alkaline phosphatase increased, edema, potassium decreased, nausea, vomiting, phosphate decreased, decreased appetite, sodium decreased, leukocytosis, magnesium decreased, aspartate aminotransferase increased, arthralgia, dyspnea, uric acid increased, abdominal pain, creatinine increased, mucositis, rash, electrocardiogram QT prolonged, differentiation syndrome, calcium decreased, neutrophils decreased, and myalgia
  • In patients with MDS, the most common adverse reactions including laboratory abnormalities (≥25%) are creatinine increased, hemoglobin decreased, arthralgia, albumin decreased, aspartate aminotransferase increased, fatigue, diarrhea, cough, sodium decreased, mucositis, decreased appetite, myalgia, phosphate decreased, pruritus, and rash
  • In patients with cholangiocarcinoma, the most common adverse reactions (≥15%) in patients with cholangiocarcinoma are fatigue, nausea, abdominal pain, diarrhea, cough, decreased appetite, ascites, vomiting, anemia, and rash. The most common laboratory abnormalities (≥10%) in patients with cholangiocarcinoma are hemoglobin decreased, aspartate aminotransferase increased, and bilirubin increased


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.

Advise women not to breastfeed.
