Calquence basics
Calquence contains the active ingredient acalabrutinib. It belongs to a group of drugs called kinase inhibitors.
Calquence is a brand-name medication. A generic version of the drug isn’t currently available.
Calquence is used to treat CLL, SLL, and MCL in certain adults.
| Description | Symptoms | |
|---|---|---|
| CLL | type of cancer that affects white blood cells in bone marrow (the tissue inside bones) | • fatigue (low energy) • fever or chills • frequent infections or illness |
| SLL | type of cancer that affects white blood cells in lymph nodes (part of your immune system, which helps you fight infections) | • unexplained weight loss • painless swelling in the neck, armpit, and groin • shortness of breath |
| MCL | type of non-Hodgkin’s lymphoma that occurs when white blood cells begin to grow abnormally and reproduce quickly (abnormal cells are usually found in lymph nodes, bone marrow, digestive tract, and blood) | • fever or night sweats • digestive problems, such as abdominal pain, nausea, or vomiting • feeling generally unwell |
For MCL, Calquence may be used on its own in adults who have received at least one other medication to treat MCL.
Calquence can also be used in adults with MCL who are not eligible for autologous hematopoietic stem cell transplantation (HSCT) and have not received other medication for MCL. In these cases, Calquence is used in combination with bendamustine (Treanda) and rituximab (Rituxan).
How it works
Calquence works by blocking the growth of the abnormal white blood cells.
It does this by blocking a protein called Bruton tyrosine kinase (BTK). This protein helps white blood cells grow. By blocking BTK, Calquence helps reduce the growth of white blood cells. This kills the abnormal white blood cells that are causing the cancer.
Like most drugs, Calquence may cause mild to serious side effects. The following lists contain some of the more common side effects Calquence may cause, but they don’t include all possible side effects.

- other medications you take
Your doctor or pharmacist can tell you more about the potential side effects of Calquence. They can also suggest ways to help reduce side effects.
Note: After the Food and Drug Administration (FDA) approves a drug, it tracks and reviews side effects of the medication.
