Patient leaflet - Exkivity 40 mg hard capsules

1. What EXKIVITY is and what it is used for

This medicine is a cancer medicine that contains the active substance mobocertinib. This medicine is used to treat adults with a type of lung cancer called ‘non-small cell lung cancer’ (NSCLC) that is caused by a specific change in the EGFR (epidermal growth factor receptor) gene.

It is used when:

  • a test has shown that your cancer cells contain an ‘exon 20 insertion mutation’ in the EGFR gene and

    has spread within the lung or to other organs in your body and cannot be removed by surgery. • your cancer has been previously treated with a type of chemotherapy that contains platinum

    (e.g., cisplatin or carboplatin).

How EXKIVITY works

EXKIVITY works by blocking the activity of EGFR when your cancer contains a modification called ‘exon 20 insertion mutation.’ This modified EGFR is known to be involved in the growth and spread of cancer cells. EXKIVITY may slow or stop cancer cells from growing.

In general, the sooner and better diarrhoea is managed, the more likely it will be controlled and tolerable.

  • heart problems, including heart failure and abnormal electrical activity of the heart (a heart conduction problem called ‘prolonged QTc interval)’

    EXKIVITY may cause heart problems, which have the potential to be fatal. Your doctor or nurse should check your heart function before you start taking EXKIVITY and during treatment as needed. Tell your doctor or nurse right away if you have any signs and symptoms of a heart problem, including feeling like your heart is pounding or racing, irregular heartbeat, shortness of breath, chest pain, swelling of your ankles and feet, or feeling faint, dizzy or lightheaded. • lung problems

    EXKIVITY may cause inflammation of the lungs, which has the potential to be fatal. Symptoms may be similar to those symptoms from lung cancer. Tell your doctor or nurse right away if you develop any new or worsening symptoms, including trouble breathing or shortness of breath, cough, or fever.
