In short
In the European Union, ivosidenib is indicated in combination with azacitidine for treating adults with newly diagnosed acute myeloid leukaemia (AML) with an IDH1 R132 mutation who cannot receive standard induction chemotherapy, and as monotherapy for adults with previously treated, locally advanced or metastatic cholangiocarcinoma with an IDH1 R132 mutation. In the United States, it is indicated for adults with a susceptible IDH1 mutation who have newly diagnosed AML and are 75 years or older or have comorbidities precluding intensive induction chemotherapy, used either in combination with azacitidine or as monotherapy. The United States approval also covers adult patients with a susceptible IDH1 mutation who have relapsed or refractory AML, relapsed or refractory myelodysplastic syndromes, or previously treated locally advanced or metastatic cholangiocarcinoma.

About this page. This page brings together public information from official sources, each cited where it is used. It is not medical advice, it is not a diagnosis, and it does not tell you which treatment to take.
Treatments. Indications are quoted unchanged from official product information (European Medicines Agency, U.S. Food and Drug Administration). They describe what a medicine is approved for, not whether it is right for you. Approved uses can differ between countries. Always read the package leaflet and follow your doctor's or pharmacist's advice.
What people report. Figures marked "reported by Anpheros users" are anonymous counts from at least 20 people who agreed to share them. They show what people report, not what works, and they are not clinical evidence.
Links between terms. "May be associated with" means the link appears in a cited source. It does not mean you have that condition.
In an emergency, call 112 (or your local emergency number). Do not delay seeking medical help because of something you read here.
