What is Iclusig?

Iclusig is a cancer medicine that interferes with the growth of some cancer cells.

Iclusig is used to treat adults with chronic phase  chronic myeloid leukemia  (CML) who did not tolerate or no longer benefit from treatment with at least 2 prior kinase inhibitor medicines.

Iclusig is used to treat adults with accelerated phase or blast phase CML, or Philadelphia chromosome positive  acute lymphoblastic leukemia  (Ph+ ALL) who cannot receive any other kinase inhibitor medicines.

Iclusig is also used to treat adults with a specific type of abnormal gene (T315I-positive) chronic phase, accelerated phase, or blast phase CML, or T315I-positive Ph+ ALL.

Iclusig is not for use to treat people with newly diagnosed chronic phase CML.

It is not known if Iclusig is safe and effective in children.
