Uses of Acalabrutinib

Acalabrutinib is used to treat people with mantle cell lymphoma (MCL; a fast-growing cancer that begins in the cells of the immune system) who have already been treated with at least one other chemotherapy medication. It is also used alone or with obinutuzumab (Gazyva) to treat chronic lymphocytic leukemia (CLL; a type of cancer that begins in the white blood cells) and small lymphocytic lymphoma (SLL: a type of cancer that begins in the white blood cells). Acalabrutinib is in a class of medications called kinase inhibitors. It works by blocking the action of the abnormal protein that signals cancer cells to multiply. This helps stop the spread of cancer cells.
