简要总结

A multicenter, randomized, double-blind placebo-controlled study to report the efficacy and safety of all-trans etinoic acid compared to placebo for the treatment of adults with corticosteriod-resistant/relapsed primary immune thrombocytopenia (ITP).

详细描述

The investigators are undertaking a parallel-group, multicenter, randomized controlled trial of 192 adults with corticosteriod-resistant/relapsed primary ITP. Patients were randomized to all-trans etinoic acid and placebo group. Platelet count, bleeding, and other symptoms were evaluated before and after treatment. Adverse events are also recorded throughout the study.
