Efgartigimod IV for adolescents (12–17) with chronic immune thrombocytopenia
This trial will try intravenous efgartigimod to see if it safely raises platelet counts in people aged 12 to 17 with chronic ITP.
-
Follow-up mezagitamab treatment for adults with chronic primary immune thrombocytopenia
This follow-up will try giving mezagitamab longer-term to adults with chronic primary ITP who completed earlier mezagitamab studies to see if it stays safe, is tolerated, and helps maintain platelet responses.
-
Mezagitamab treatment for adults with chronic immune thrombocytopenia
This study is testing if a new treatment called mezagitamab can help adults with chronic immune thrombocytopenia keep their platelet counts stable compared to a placebo.
