What is ivosidenib?

See also: Xospata

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.

Ivosidenib is used to treat acute myeloid leukemia (AML) in adults with an IDH1 mutation. ivosidenib is used when AML has come back or has not improved with prior treatment.

Ivosidenib may also be used for purposes not listed in this medication guide.

Important Information

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, dizziness, cough, trouble breathing, swelling, rapid weight gain, rash, or decreased urination.

Before taking this medicine

Tell your doctor if you have ever had:

  • heart disease;

  • long QT syndrome (in you or a family member);

  • nerve problems; or

  • an electrolyte imbalance (such as low levels of potassium, sodium, or magnesium in your blood).

Ivosidenib may harm an unborn baby. Use a barrier form of birth control (condom or diaphragm with spermicide) to prevent pregnancy while you are using ivosidenib. Hormonal contraception (birth control pills, injections, implants, skin patches, and vaginal rings) may not be effective enough to prevent pregnancy during your treatment.

ivosidenib may affect fertility (ability to have children) in both men and women. However, women should still use birth control to prevent pregnancy because ivosidenib can harm an unborn baby.

You should not breast-feed while using this medicine, and for at least 1 month after your last dose.
