NCT ID NCT05223920

First seen Jun 26, 2026 · Last updated Jun 26, 2026

Summary

This study looks at the long-term safety of bomedemstat, an oral drug, in 81 people with myeloproliferative neoplasms (MPNs) like essential thrombocythemia and primary myelofibrosis. Participants had already taken bomedemstat in a prior study. Researchers tracked side effects, spleen size, and platelet counts to see if the drug remains safe and effective over time.

What this could lead to

If successful, this study could show that bomedemstat is safe and effective for long-term control of myeloproliferative neoplasms, offering a new treatment option.

What could go wrong
