Adverse events

Tazemetostat in Treating Patients With Relapsed or Refractory Advanced Solid Tumors, Non-Hodgkin Lymphoma, or Histiocytic Disorders With EZH2, SMARCB1, or SMARCA4 Gene Mutations (A Pediatric MATCH Treatment Trial) · Source last updated 2026-04-13

Results reported by the registry submitting party. Population, time horizon, units and missing values must be read together.

Adverse events occurred during the study; they are not necessarily caused by treatment. Serious events are not interchangeable with severe/grade 3–4 events. These safety populations may differ from efficacy populations.

Collection time frame
From enrollment to 30 days after the end of treatment, up to 2 years
Other-event reporting threshold
0%

Adverse event reporting is collected routinely using case report forms. The SAE table reflects NCI Common Terminology Criteria for Adverse Events (CTCAEs) submitted by the institution via expedited reporting (NCI AdEERs / CAeRs). All remaining CTCAEs collected by means other than expedited reporting are non-serious and are reported in the "AE Other" table. All-Cause Mortality includes all deaths collected on the study. Ineligible patients are excluded from reporting of adverse events.
