ROZLYTREK 200 MG HARD CAPSULES - patient leaflet, side effects, dosage

1. what rozlytrek is and what it is used for

What Rozlytrek is

Rozlytrek is a cancer medicine that contains the active substance entrectinib.

What Rozlytrek is used for

Rozlytrek is used to treat either:

• adults and children 12 years of age and older with solid tumour (cancer) in various parts of the body that is caused by a change in the neurotrophic tyrosine receptor kinase (NTRK) gene, or
• adults with a type of lung cancer called ‘non-small cell lung cancer’ (NSCLC) that is caused by a change in the ROS1 gene.

NTRK gene fusion-positive solid tumour cancer

It is used when:

• a test has shown that your cancer cells have a change in genes called ‘NTRK’ and has spread within the affected organ or to other organs in your body or if surgery to remove the cancer is likely to result in severe complications (see ‘How Rozlytrek works’ below), and
• you have not received treatment with medicines called NTRK inhibitors
• other treatments have not worked or are not suitable for you.

ROS1 -positive non-small cell lung cancer (NSCLC)

It is used if your lung cancer:

• is ‘ ROS1 -positive’ – this means that your cancer cells have

a change in a gene called ‘ROS1 ’ (see ‘How Rozlytrek works’ below),

• has spread to other parts of your body (metastatic), and
• you have not received treatment with medicines called

ROS1 inhibitors.

How Rozlytrek works

Rozlytrek works by blocking the action of abnormal enzymes caused by a change in the NTRK or ROS1 genes that make them. The faulty enzymes encourage the cancer cells to grow.

Rozlytrek may slow down or stop the cancer growing. It may also help to shrink your cancer.

This leaflet was last revised in January 2022

This medicine has been given ‘conditional approval’. This means that there is more evidence to come about this medicine.

It is not known if Rozlytrek can reduce the effect of birth control medicines (pills or implanted hormonal contraceptives). You should use another reliable method of birth control such as a barrier method (e.g. condom) so you do not become pregnant while you are taking Rozlytrek and for 5 weeks after you stop treatment.

Talk to your doctor about the right methods of contraception for you and your partner.

Men and contraception

Your female partner should not become pregnant while you are taking this medicine because it could harm the baby. If your female partner is able to become pregnant, you must use highly effective contraception while on treatment and for at least 3 months after stopping treatment. Talk to your doctor about the right methods of contraception for you and your partner.

Pregnancy

• If you become pregnant when taking the medicine or during the 5 weeks after taking your last dose, tell your doctor straight away.

Breast-feeding

Do not breast-feed while taking this medicine. This is because it is not known if Rozlytrek can pass over into breast milk and could therefore harm your baby.

• have blurred vision
• feel dizzy
