What is Venclexta Starting Pack (venetoclax)?
Venetoclax inhibits a certain protein in cancer cells (abnormal lymphocytes produced in chronic lymphocytic leukemia) that helps keep those cells alive and makes them resistant to chemotherapy. Venetoclax binds to this protein, which helps kill the cancerous lymphocytes in blood and bone marrow.
Venetoclax is used to treat chronic lymphocytic leukemia (CLL) in adults with 17p deletion. Venetoclax is used only if you have a specific genetic marker, for which your doctor will test.
Venetoclax is usually given after at least one other cancer medicine has been tried without success.
Venetoclax may also be used for purposes not listed in this medication guide.
