Ivosidenib targets a specific gene mutation called IDH1, which can affect your bone marrow. IDH1 mutation prevents young blood cells from developing into healthy adult blood cells, which can result in symptoms of
acute myeloid leukemia (AML). Ivosidenib is for use only in adults with an IDH1 mutation. Your doctor will test you for this gene.
Ivosidenib is used to treat AML after other treatments did not work or stopped working.
Ivosidenib is also used to treat AML in adults 75 years and older who have newly-diagnosed AML and cannot use certain chemotherapy treatments because of other health problems.
Ivosidenib is also used to treat bile duct cancer that has progressed or has spread to other parts of the body (metastatic) after treatment with other medicine.
Ivosidenib may also be used for purposes not listed in this medication guide.

Ivosidenib side effects:
Get emergency medical help if you have signs of an allergic reaction:
Difficult breathing; swelling of your face, lips, tongue, or throat.
Ivosidenib can cause a condition called differentiation syndrome, which affects blood cells and can be fatal if not treated. This condition may occur within 1 days to 3 months after you start taking ivosidenib .
Seek medical help right away if you have symptoms of differentiation syndrome:
- fever, cough, trouble breathing;
- dizziness;
- rash;
- decreased urination;
- rapid weight gain; or
- swelling in your arms or legs.
Common side effects of ivosidenib may include:
- irregular heartbeats;
- stomach pain or swelling, nausea, vomiting, loss of appetite;
- diarrhea, constipation; fever, tiredness;
- low red blood cell or high white blood cell counts;
- cough, shortness of breath;
- sores in your mouth or throat;
- rash;
- abnormal liver function tests;
- muscle or joint pain; orswelling in your arms or legs.
This is not a complete list of side effects and others may occur. Call your doctor for medical advice about side effects

Pregnancy & Lactation
Lactation: There are no data on the presence of Ivosidenib or its metabolites in human milk, the effects on the breastfed child, or the effects on milk production. 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 Ivosidenib and for at least 1 month after the last dose.
Precautions & Warnings:
QTc Interval Prolongation: Patients treated with Ivosenib can develop QT (QTc) prolongation and ventricular arrhythmias. Of the 258 patients with hematological malignancies treated with Ivosenib in the clinical trial (AG120-C-001), 9% were found to have a QTc interval greater than 500 msec and 14% of patients had an increase from baseline QTc greater than 60 msec. One patient developed ventricular fibrillation attributed to Ivosenib. The clinical trial excluded patients with baseline QTc of ≥ 450 msec (unless the QTc ≥ 450 msec was due to a pre-existing bundle branch block) or with a history of long QT syndrome or uncontrolled or significant cardiovascular disease.
Guillain-Barré Syndrome: Guillain-Barré syndrome can develop in patients treated with Ivosenib. Guillain-Barré syndrome occurred in <1% (2/258) of patients treated with Ivosenib in study AG120-C-001. Monitor patients taking Ivosenib 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 Ivosenib in patients who are diagnosed with Guillain-Barré syndrome.
Use in Special Populations:
Geriatric Use: No overall differences in effectiveness or safety were observed between patients who were 65 years and older compared to younger patients.
