First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 2 times

Summary

This study tests a new daily pill called JBI-802 in people with certain blood cancers (myeloproliferative neoplasms and MDS/MPN) who have too many platelets. The trial has two phases: first, finding a safe dose in about 30 adults, then checking if it works. Participants take the drug for up to 2 years if it helps and side effects are manageable.

What this could mean

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

Active substance

JBI-802 (a drug that targets two proteins, LSD1 and HDAC6, to help control abnormal blood cell growth)

What this could lead to

If this trial succeeds, it could point toward a new oral treatment option for people with certain blood cancers who have too many platelets.

What could go wrong

This is an early-phase trial with only 30 participants, so results may not apply to everyone. The drug may cause side effects or not work as hoped.
