A general class of thrombocytopenia due to immune destruction of platelets. It includes idiopathic thrombocytopenic purpura, as well as immune destruction-related thrombocytopenias due to other reasons (e.g., AIDS, transfusion, lupus erythematosus).
Biomarker and diagnostic research for thrombocytopenia due to immune destruction has been reported in the published literature.
1 FDA-approved treatment is available for thrombocytopenia due to immune destruction, including RILZABRUTINIB (WAYRILZ, approved 2025). An additional 3 compounds hold orphan drug designation.

FDA adverse event reports (FAERS) include all outcomes reported during treatment and do not establish causation. Report counts reflect all approved indications for each drug, not only this disease.
88 adverse event reports have been filed with the FDA for RILZABRUTINIB (across all indications). Most commonly reported: platelet count decreased, diarrhoea, and nausea.
Gene therapy approaches for thrombocytopenia due to immune destruction have been reported in the published literature.
