About GAVRETO® (pralsetinib)

GAVRETO® is a prescription medicine used to treat certain cancers caused by abnormal rearranged during transfection (RET) genes in:

• adults with non-small cell lung cancer (NSCLC) that has spread
• adults and children 12 years of age and older with advanced thyroid cancer or thyroid cancer that has spread who require a medicine by mouth or injection (systemic therapy) and who have received radioactive iodine and it did not work or is no longer working*

Your healthcare provider will perform a test to make sure that GAVRETO® is right for you.

It is not known if GAVRETO is safe and effective when used to treat cancers caused by abnormal RET genes in children for the treatment of NSCLC or in children younger than 12 years of age for the treatment of thyroid cancer.

*GAVRETO® was approved 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 GAVRETO®.
