Study Summary

Thrombotic thrombocytopenic purpura (TTP) is a disease characterized by small blood clots throughout the body that can damage major organs and cause death. TTP is treated with plasma exchange (also called "plasmapheresis"). Patients who do not respond initially to plasma exchange often are helped by later treatment with rituximab. The purpose of this study is to see whether combining low doses of rituximab with plasma exchange will help patients get better sooner and reduce the chance of getting TTP again.

Primary Outcome

Exacerbation is recurring TTP ≤30 days after a Treatment Response (normal platelet count for 2 days) and discontinuation of plasma exchange. Refractory TTP is failure to achieve a Treatment Response by day 28, or failure to achieve a Durable Treatment Response (lasting at least 30 days) by day 60.
