Tazverik

Generic name: Tazemetostat
Drug class: Miscellaneous antineoplastics

Usage of Tazverik

Tazverik is used to treat adults and pediatric patients aged 16 years and older with advanced epithelioid sarcoma, a rare slow-growing type of soft tissue cancer. This medicine is used when the cancer has spread to other parts of the body (metastatic) or cannot be removed with surgery.

Tazverik is also used to treat follicular lymphoma when the disease has come back or did not respond to treatment in adults:

whose tumors have an abnormal EZH2 gene, and who have been treated with at least two prior medicines. Your healthcare provider will perform a test to make sure Tazverik is right for you.

who have no other satisfactory treatment options.

Tazverik was approved by the US Food and Drug Administration (FDA) on an "accelerated" basis. In clinical studies, some people responded to this medicine, but further studies are needed.
