Tazverik is the first approved selective inhibitor of EZH2 methyltransferase. It works by preventing methylation of a specific histone, which alters gene expression patterns associated with cancer cell growth. 

In a Phase II study of people with epithelioid sarcoma, Tazverik demonstrated a 15% response rate, with two thirds of responses lasting at least six months. In a study of people with follicular lymphoma, the overall response rate was 69%. Tazverik was first approved in January 2020.
