What is Calquence?
Calquence is a targeted therapy medication used to treat certain types of B-cell cancers, such as mantle cell lymphoma (MCL), chronic lymphocytic leukemia (CLL), and small lymphocytic lymphoma (SLL). As an oral chemotherapy drug containing the active ingredient acalabrutinib, it offers a modern approach to cancer treatment. Manufactured by AstraZeneca, Calquence is prescribed for adults, often as a second-line treatment for MCL after at least one prior therapy has been attempted, or as a primary or subsequent treatment for CLL and SLL. It is designed to specifically target cancer cells, minimizing damage to surrounding healthy cells.
How does Calquence work?
Calquence works by selectively blocking an enzyme called Bruton’s tyrosine kinase (BTK), which is crucial for the survival and growth of malignant B-cells. In cancers like CLL and MCL, BTK is overactive, sending constant signals that tell cancer cells to multiply and survive. Acalabrutinib, the active ingredient in Calquence, is a highly selective BTK inhibitor. By binding to and blocking this enzyme, it interrupts the signaling pathway, which in turn leads to the death of the cancer cells (a process known as apoptosis) and helps to control the spread of the lymphoma.
Who is Calquence for?
Calquence is primarily for adults diagnosed with specific B-cell cancers, including mantle cell lymphoma (MCL), chronic lymphocytic leukemia (CLL), or small lymphocytic lymphoma (SLL). It is specifically indicated for MCL patients who have already undergone at least one other treatment. For those with CLL or SLL, Calquence may be prescribed as an initial (first-line) therapy or as a treatment following other therapies. It is a suitable option for patients who require an oral, targeted medication and can be managed in an outpatient setting under the supervision of an oncologist. This medication is not intended for use in children.
Dosage and administration
The standard dosage for Calquence is typically one 100 mg capsule taken orally twice daily, approximately 12 hours apart. You should swallow the capsules whole with a full glass of water; do not crush, chew, or open them. If you take heartburn medications like antacids, they must be administered at least two hours before or two hours after your Calquence dose. If you forget a dose, take it as soon as you remember if it has been three hours or less. If more than three hours have passed, skip the missed dose and resume your normal schedule. Never take a double dose to make up for a missed one. Your oncologist will determine your exact regimen.
Side effects
While many people tolerate Calquence well, common side effects can include headache, diarrhea, muscle and joint pain, bruising, fatigue, and nausea. These symptoms are often mild and manageable. However, more serious side effects can occur and require immediate medical attention. A significant risk is bleeding, so any signs like blood in stool or urine, coughing up blood, or unusual bleeding should be reported to your doctor. Other serious risks include an increased chance of infections, the development of new cancers (particularly skin cancer), and heart rhythm problems like atrial fibrillation. Always discuss any persistent or concerning symptoms with your healthcare provider.

Calquence (acalabrutinib) is indicated for the treatment of adult patients with:
- Mantle Cell Lymphoma (MCL) who have received at least one prior therapy.
- Chronic Lymphocytic Leukemia (CLL) or Small Lymphocytic Lymphoma (SLL).
It is a targeted therapy that helps manage these forms of non-Hodgkin lymphoma by inhibiting cancer cell growth.
