Summary Reports
Consumer Information
This information was provided by the drug’s manufacturer when this drug product was approved for sale in Canada. It is designed for consumers and care givers. It is a summary of information about the drug and will not tell you everything about the drug. Contact your doctor or pharmacist if you have any questions about the drug.
What the medication is used for
IDHIFA is used to treat Acute Myeloid Leukemia (AML) in adults with a particular change (mutation) in the enzyme “IDH2”. AML is a form of cancer which affects your bone marrow and can cause problems with producing normal blood cells.
IDHIFA is used when your AML:
- has come back (relapsed) or,
- has not improved with another treatment (refractory).
A Notice of Compliance with Conditions (NOC/c) is a type of approval to sell a drug in Canada.
Health Canada only gives an NOC/c to a drug that treats, prevents, or helps identify a serious or life-threatening illness. The drug must show promising proof that it works well, is of high quality, and is reasonably safe. Also, the drug must either respond to a serious medical need in Canada, or be much safer than existing treatments.
Drug makers must agree in writing to clearly state on the label that the drug was given an NOC/c, to complete more testing to make sure the drug works the way it should, to actively monitor the drug’s performance after it has been sold, and to report their findings to Health Canada.
What it does
Normal “IDH2” enzyme plays an important role in making energy for cells. Changes (mutations)
in the enzyme in the bone marrow can cause cancers such as AML. These changes cause the
bone marrow to stop producing normal blood cells that fight infection or stop bleeding. IDHIFA
blocks the mutated “IDH2” enzyme. This increases the number of normal blood cells.
This medicine should only be used to treat AML with the “IDH2” mutation. Therefore, before
starting treatment your doctor will test for this mutation.
It may take up to six months to see the full effect of IDHIFA on your AML.
Talk to your healthcare professional if you have any questions about how IDHIFA works or why
