The U.S. Food and Drug Administration (FDA) is alerting patients and health care providers about the voluntary withdrawal of Tazverik (tazemetostat) tablets from the market due to an increased rate of hematologic second primary malignancies (SPMs) — the development of new blood cancers in people treated with Tazverik for a different cancer. As a result, it was determined that the risks of treatment with Tazverik outweigh its benefits.
