Tazverik Approved for Follicular Lymphoma

Share

FDA has granted Epizyme accelerated approval for Tazverik (tazemetostat), an EZH2 inhibitor for adult patients with relapsed or refractory follicular lymphoma (FL) whose tumors are positive for an EZH2 mutation as detected by an agency-approved test and who have received at least two prior systemic therapies, and for adult patients who have no satisfactory alternative treatment options. The companion diagnostic, Roche Molecular Systems’ cobas EZH2 Mutation Test, was approved too.

 

Tazverik’s approval was based on data from two open-label, single-arm cohorts of a multi-center trial (Study E7438-G000-101, NCT01897571) in patients with histologically confirmed follicular lymphoma after at least two prior systemic therapies. The overall response rate in 42 patients with EZH2 mutant FL was 69%, with 12% having complete responses and 57% partial responses, an FDA release says. The most common adverse reactions in patients with follicular lymphoma included fatigue, upper respiratory tract infection, musculoskeletal pain, nausea and abdominal pain, it says, adding that serious adverse reactions occurred in 30% of patients with most of these caused by infection.
