New pill could help blood disorder patients when standard care fails
NCT ID NCT07007962
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests an oral drug called rilzabrutinib in adults with immune thrombocytopenia (ITP), a condition where the immune system destroys platelets, causing bleeding risks. Participants must have failed first-line treatment. The goal is to see if the drug can raise platelet counts to safer levels. About 60 people will take the drug for up to 28 weeks, with some continuing longer.
