Rozlytrek is a new oral medicine approved by the FDA to treat two kinds of advanced cancer. One is a type of lung cancer called ROS1-positive non-small cell lung cancer in adults. The other is solid tumors with an NTRK gene fusion in adults and children older than 1 month. These tumors must be metastatic or hard to remove with surgery, and they must have grown after other treatment or have no good treatment options.
Doctors will use an FDA-approved test to check if a patient's cancer has the ROS1 or NTRK change. Rozlytrek comes as capsules or oral pellets and is taken once a day with or without food. Before starting, doctors will check the heart, uric acid levels, and heart rhythm.
The approval gives patients with these specific gene changes another treatment option. For the NTRK solid tumor use, the approval is based on how well tumors shrank and how long that response lasted. More studies are needed to confirm the long-term benefit.
Rozlytrek is not for everyone. Only patients whose cancer has the right gene marker can use it. If you or a loved one has cancer, talk with your doctor about whether testing for these markers is right for you.
