Servier Highlights Novel Approaches to Treating Cancer at the ASCO and EHA 2021 Annual Meetings

  • Wide range of research across five tumor types underscores breadth of data in Servier’s growing oncology portfolio
  • Final overall survival analysis from pivotal Phase 3 ClarIDHy study of TIBSOVO® (ivosidenib tablets) in previously treated IDH1-mutant cholangiocarcinoma patients to be presented at ASCO 2021 – data support recently accepted supplemental New Drug Application for TIBSOVO

BOSTON, Mass., June 1, 2021 – Servier, a growing leader in oncology committed to bringing the promise of tomorrow to the patients we serve, today announced that data will be presented from multiple studies across its oncology portfolio during the 2021 American Society of Clinical Oncology (ASCO) Virtual Annual Meeting, June 4-8 and the European Hematology Association (EHA) 2021 Virtual Congress, June 9-17. Data presented at ASCO and EHA include multiple company-sponsored and investigator-initiated trials, which underscore the depth and breadth of Servier’s oncology portfolio that is making strides toward addressing unmet needs of those living with cancer.

Three abstracts have been selected for oral presentation, spanning multiple hard-to-treat solid tumor types, including glioma, biliary tract cancer, and colorectal cancer. These presentations highlight the potential role of IDH inhibition and the company’s overall innovative research portfolio in generating superior outcomes over current standards of care based on precision approaches. Research from several investigator-initiated trials will also be shared. These studies investigate evolving the standard of care in advanced cancers through the use of combination approaches in metastatic colorectal cancer, myeloid malignancies, gastric and gastroesophageal adenocarcinoma, and biliary tract cancer.

In addition, there will be an encore poster presentation of the final results from ClarlDHy, the first and only randomized Phase 3 trial for previously treated IDH1-mutated cholangiocarcinoma. Data from this study were included in the company’s supplemental New Drug Application for TIBSOVO, which was recently accepted and granted Priority Review by the U.S. Food and Drug Administration. Currently, there are no approved systemic therapies for IDH1-mutated cholangiocarcinoma and limited chemotherapy options are available for patients with advanced disease.

“Our presence at this year’s ASCO and EHA showcase the very focused approach we are taking to place an emphasis on difficult-to-treat cancers with significant unmet need,” said David K. Lee, CEO, Servier Pharmaceuticals. “We believe that our leadership in hematology and growing position in solid tumors ensures we are well poised to deliver more life-changing medicines to a greater number of individuals impacted by cancer worldwide.”

Servier has experienced tremendous growth in the past several years. Much of this expansion is in the oncology space where the company is now allocating 50 percent of its research and development investment. With 19 oncology assets at varying stages of clinical development, and 20 research projects[1], Servier is addressing areas of significant unmet need and difficult-to-treat cancers that target different types of lymphoma and leukemia, as well as solid tumors including gastrointestinal and lung cancers.

“Our significant presence at these key congresses is reflective of the successful expansion of our research and development for a variety of tumor types to benefit patients,” said Claude Bertrand, Executive Vice President of Research and Development, Servier Group. “We are excited to present data across our hematology and solid tumor portfolio including research on the potential of IDH inhibition in the treatment of cancers with high unmet needs.”

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.



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.


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.


  • The most common adverse reactions including laboratory abnormalities (≥20%) were hemoglobin decreased (60%), fatigue (43%), arthralgia (39%), calcium decreased (39%), sodium decreased (39%), leukocytosis (38%), diarrhea (37%), magnesium decreased (36%), edema (34%), nausea (33%), dyspnea (32%), uric acid increased (32%), potassium decreased (32%), alkaline phosphatase increased (30%), mucositis (28%), aspartate aminotransferase increased (27%), phosphatase decreased (25%), electrocardiogram QT prolonged (24%), rash (24%), creatinine increased (24%), cough (23%), decreased appetite (22%), myalgia (21%), constipation (20%), and pyrexia (20%).
  • 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.

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.
