Valemetostat (trade name Ezharmia) is a drug used for the treatment of adult T-cell leukemia/lymphoma (ATL). Valemetostat is an inhibitor of the enzymes enhancer of zeste homolog 1 (EZH1) and enhancer of zeste homolog 2 (EZH2), which are implicated in the etiology of some forms of cancer including non-Hodgkin lymphomas. In Japan, valemetostat was approved in September 2022 for patients with relapsed or refractory adult T-cell leukemia/lymphoma. References
