NCT ID NCT02875548

First seen Jun 27, 2026 · Last updated Jun 27, 2026

Summary

This study offers continued access to tazemetostat for 58 people with various cancers who already benefited from the drug in earlier trials. The main goal is to monitor long-term safety and side effects. Participants must have shown clinical benefit from tazemetostat before joining.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance

tazemetostat (a targeted cancer drug)

What this could lead to

If successful, this study could confirm that long-term use of tazemetostat is safe for people with certain cancers, supporting its continued use as a treatment option.

What could go wrong

This is a rollover study, not a new treatment test, so it won't prove whether tazemetostat works better than other options. Long-term side effects are still being monitored.
