New pill could help ITP patients who failed standard treatments
NCT ID NCT07294365
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This phase 2 trial tests an experimental oral drug called DZD8586 (Birelentinib) in adults with primary immune thrombocytopenia (ITP) whose condition did not improve after at least one standard therapy. About 60 participants will receive one of three dose levels to see if it safely raises platelet counts. The study aims to find a new treatment option for people with persistent or chronic ITP.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- DZD8586 (Birelentinib)
- What this could lead to
- If it works, this could offer a new oral treatment option for people with ITP who have not responded to standard therapies.
- What could go wrong
- This is an early phase 2 trial with only 60 participants, so results may not apply to everyone. The drug may cause side effects or fail to improve platelet counts.
