Rozlytrek specifically contains the active pharmaceutical drug entrectinib. It belongs to a group of medicines called anti-neoplastic (or anti-cancer) agents which are used for the treatment of cancer.
Rozlytrek (entrectinib) is designed to work by inhibiting the action of enzymes which have an alteration in them. This is due to the alteration in the NTRK or ROS1 genes that creates them. The altered enzymes encourage the cancerous cells to grow. This medication may resist or stop the cancer progression. It may also help in order to shrink the cancer. Rozlytrek is typically available in 100 mg and 200 mg capsules.
Solid Tumors: The rozlytrek capsule is authorized to treat adult and pediatric patients with neurotrophic tyrosine receptor kinase (NTRK) fusion-positive locally advanced or metastatic solid tumors, who have progressed after previous therapies, or as initial therapy when there are no acceptable standard therapies.
Non-small cell lung cancer (NSCLC): Capsule of rozlytrek is also authorized to treat patients with ROS1-positive, locally advanced or metastatic non-small cell lung cancer (NSCLC).
Note: Other drugs used for the treatment of Non-small cell lung cancer are as follows:
Posology and Method of Administration
Rozlytrek (entrectinib capsule) can be taken either with or without food, swallowed completely or whole and must not be opened or dissolved.
Adults: The recommended dose for adult patients is 600 mg given orally (by mouth), once daily.
Pediatric patients: The recommended dose for pediatric patients who have the ability to swallow capsules is 300 mg/m2 orally (by mouth), once daily.
The recommended dose for paediatric patients aged 12 years or older is based on body surface area (BSA); the dose for paediatric patients with a BSA of 1.11 to 1.50 m2

Duration of Treatment: Treatment with Rozlytrek is recommended to continue until the disease is progressive or unacceptable toxicity occurs.
A validated assay is needed for the selection of patients with NTRK gene fusion +Ve solid tumours. NTRK gene fusion +Ve status must be established before initiating therapy with entrectinib. This treatment should be started by a health specialist experienced in the use of anticancer medicinal products.
