Venetoclax Overview
-
Venetoclax is used alone or in combination with obinutuzumab (Gazyva) or rituximab (Rituxan) to treat certain types of chronic lymphocytic leukemia (CLL; a type of cancer that begins in the white blood cells) or certain types of small lymphocytic lymphoma (SLL; a type of cancer that begins mostly in the lymph nodes). It is also used in combination with either azacitidine (Vidaza), decitabine (Dacogen), or cytarabine as a first treatment for acute myeloid leukemia (AML; a type of cancer that begins in the white blood cells) in people 75 years of age or older, or in adults who have medical conditions that prevents them from being treated with other chemotherapy medications. Venetoclax is in a class of medications called B-cell lymphoma-2 (BCL-2) inhibitors. It works by blocking the action of a certain protein in the body that helps cancer cells survive. This helps to kill cancer cells.
