What is ROZLYTREK?
ROZLYTREK is a prescription medicine used to treat:
- Adults with non-small cell lung cancer (NSCLC) that has spread to other parts of the body and is caused by an abnormal ROS1 gene.
- Adults and children 12 years and older with solid tumors (cancer) that:
- are caused by certain abnormal NTRK genes and
- have spread or if surgery to remove their cancer is likely to cause severe complications, and
- there is no satisfactory alternative treatment option or the cancer grew or spread on other treatment.
It is not known if ROZLYTREK is safe and effective for use in children less than 12 years of age.
ROZLYTREK was approved through a faster FDA review process based on the percentage of patients whose tumor size shrank or disappeared after treatment and how long that response lasted. There are ongoing studies to confirm the benefit of ROZLYTREK for this use.
