New oral drug shows promise for Long-Term control of rare bleeding disorder
NCT ID NCT07216079
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 2 times
Summary
This study is for adults with chronic immune thrombocytopenia (ITP), a condition where the immune system destroys platelets, causing bleeding and bruising. It tests the long-term safety and benefit of an oral drug called rilzabrutinib. Only 4 participants who already benefited from the drug in a prior study will continue treatment. The goal is to see if the drug remains safe and effective over time.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- rilzabrutinib (oral tablet)
- What this could lead to
- If successful, this study could show that rilzabrutinib is a safe and effective long-term treatment option for managing chronic immune thrombocytopenia.
- What could go wrong
- This is a very small extension study (only 4 participants) with no placebo group, so results may not apply broadly. Long-term safety and effectiveness are still being evaluated.
