    • Long-term follow up data, including updated overall survival, from the Phase 3 AGILE study of TIBSOVO® (ivosidenib) plus azacitidine in patients with previously untreated IDH1-mutant acute myeloid leukemia (AML) who are not eligible to receive intensive chemotherapy.
    • Long-term follow-up data for TIBSOVO monotherapy in patients with IDH1-mutant conventional chondrosarcoma, a rare bone malignancy for which there are no approved systemic therapies.
    • Clinical and molecular characteristics for patients with relapsed/refractory IDH1-mutant AML with an exceptional response to TIBSOVO.

    About TIBSOVO® (ivosidenib tablets)

    TIBSOVO is an oral targeted IDH1 inhibitor. The NMPA of China has approved the NDA of TIBSOVO for the treatment of adult patients with relapsed/refractory acute myeloid leukemia who have a susceptible IDH1 mutation.

    TIBSOVO is approved in the U.S.for patients with a susceptible 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 the use of intensive induction chemotherapy
    • Relapsed or Refractory AML : For the treatment of adult patients with relapsed or refractory AML
    • Locally Advanced or Metastatic Cholangiocarcinoma : For the treatment of adult patients with locally advanced or metastatic cholangiocarcinoma who have been previously treated

    Tibsovo is also approved by the European Commission as a targeted therapy in two indications: in combination with azacitidine for the treatment of adult patients with newly diagnosed acute myeloid leukemia (AML) with an isocitrate dehydrogenase-1 (IDH1) R132 mutation who are not eligible to receive standard induction chemotherapy; as well as in monotherapy for the treatment of adult patients with locally advanced or metastatic cholangiocarcinoma with an IDH1 R132 mutation who were previously treated by at least one prior line of systemic therapy.

    Servier has granted an exclusive license to CStone to develop and commercialize the product in Mainland China, Taiwan, Hong Kong, Macau and Singapore.
