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.
