1. What Calquence is and what it is used for

What Calquence is

Calquence is a medicine used to treat cancer.

  • Calquence contains the active substance acalabrutinib.
  • It belongs to a group of medicines called Bruton tyrosine kinase (BTK) inhibitors.

What Calquence is used for

Calquence is used to treat adults with chronic lymphocytic leukaemia (CLL).

CLL is a cancer of white blood cells called B-lymphocytes (or B-cells). These cells are part of the immune system (the body’s defences).

How Calquence works

Calquence works by blocking BTK, a protein in the body that helps these cancer cells grow and survive. By blocking BTK, Calquence helps to kill and can reduce the number of cancer cells which can slow down the worsening of the disease.

If you have any questions about how Calquence works or why this medicine has been prescribed for you, ask your doctor, pharmacist or nurse.

2. What you need to know before you take Calquence

Do not take Calquence if:

  • you are allergic to acalabrutinib or any of the other ingredients of this medicine (listed in section 6).

If you are not sure, talk to your doctor, pharmacist or nurse before taking Calquence.

Warnings and precautions

  • have ever had unusual bruising or bleeding or are on any medicines that increase your risk of bleeding (see section 4 ‘Possible side effects’).
  • have an infection (see section 4 “Possible side effects’)
  • have recently had an operation or are about to have one. Your doctor may stop treatment with Calquence before and after a medical, surgical or dental procedure.
  • have ever had hepatitis B (a liver infection) – this is because Calquence could cause hepatitis B to become active again and so that your doctor will look out for signs of this infection coming back (see section 4 ‘Possible side effects’).
  • have or ever had irregular heart beat (see section 4 ‘Possible side effects’).

Talk to your doctor if you develop a new lesion or any change in the appearance of an area on the skin as you are at a high risk of developing skin cancer, see section 4. Use sun protection and make regular skin examination.

Your doctor will check your blood cell counts as needed during treatment.
