1. What Jaypirca is and what it is used for

Jaypirca is a cancer medicine that contains the active substance pirtobrutinib. It belongs to a class of medicines called Bruton’s tyrosine kinase (BTK) inhibitors.

It is used on its own (monotherapy) to treat the following blood cancers in adult patients who have been previously treated with another BTK inhibitor:

  • Mantle cell lymphoma (MCL) . MCL is an aggressive (fast growing) cancer of a type of white blood cell called B-cells. B-cells are part of the immune system (the body’s natural defences). This medicine is used when the cancer has come back (relapsed), or treatment has not worked (refractory).
  • Chronic lymphocytic leukaemia (CLL): a type of cancer affecting white blood cells called lymphocytes. This medicine is used when the cancer has come back (relapsed), or treatment has not worked (refractory).

How Jaypirca works

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

2. What you need to know before you take Jaypirca
Do not take Jaypirca
  • If you are allergic to pirtobrutinib or any of the other ingredients of this medicine (listed in section 6).

Warnings and precautions

Talk to your doctor, pharmacist or nurse before taking Jaypirca:

  • If you have an infection or are at an increased risk of developing an opportunistic infection (infections seen in patients with a weakened immune system). Your doctor may give you medicines to treat or prevent infections.
  • If you have or ever had unusual bruising or bleeding or are on any medicines or supplements that could increase your risk of bleeding. See section “Other medicines and Jaypirca” below.
  • If you recently had low counts of red blood cells (anaemia), neutrophils (a type of white blood cell that fights infections) or platelets (components that help the blood to clot).
  • If you have recently had any surgery or are planning to have surgery. Your doctor may ask you to stop taking Jaypirca for a short time (3 to 5 days) before and after your surgery.
  • If you have or ever had an irregular heartbeat or have other heart and/or blood vessel problems, such as high blood pressure, history of a heart attack or have heart valve damage.
  • If you have liver problems.

You may get infections during treatment with Jaypirca. Contact your doctor if you have fever, chills, weakness, confusion, body aches, cough, cold or flu symptoms, feel tired, feel short of breath, have pain or burning feeling when passing urine. These could be signs of an infection.

Talk to your doctor if you develop a new lesion or any change in the appearance of an area on the skin, as treatment with Jaypirca may increase your risk of developing skin cancer. Use sun protection and make regular skin examinations.

Unusual levels of chemicals in the blood caused by the fast breakdown of cancer cells, known as tumour lysis syndrome (TLS), have been reported rarely during treatment with Jaypirca. This may lead to changes in kidney function, abnormal heartbeat, or seizures. Your doctor or another healthcare professional may do blood tests to check for TLS.

Your doctor will monitor you for the signs and symptoms of bleeding (see section 4) and check your blood cell counts as needed during treatment.

Your doctor may monitor your heart rhythm for any irregularities throughout treatment.

Liver problems can happen in people treated with Jaypirca. Your healthcare provider will do blood tests to check your liver before and during treatment with Jaypirca. Tell your healthcare provider or get medical help right away if you have any signs of liver problems, including stomach pain or discomfort, dark-colored urine, or yellow skin and eyes.

Children and adolescents

Do not give Jaypirca to children and adolescents aged less than 18 years. This is because it has not been studied in this age group.

Other medicines and Jaypirca

Tell your doctor or pharmacist if you are taking, have recently taken or might take any other medicines.

  • anticoagulants such as warfarin, heparin and other medicines for treating or preventing blood clots,
