What is Calquence?
Calquence (acalabrutinib) belongs to a class of medications called kinase inhibitors. Alabrutinib works by blocking the action of the abnormal protein that signals cancer cells to multiply. This helps stop the spread of cancer cells.
Calquence 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.
Calquence 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).
Calquence can make it easier for you to bleed. Contact your doctor or seek emergency medical attention if you have any bleeding that will not stop.
Call your doctor at once if you have signs of bleeding inside your body, such as: dizziness, weakness, confusion, headache, speech problems, black or bloody stools, pink or brown urine, or coughing up blood or vomit that looks like coffee grounds.
