Overview
The objective of this national, prospective, multi-centre observational study is to describe the prescription rational and practice in Germany, confirm the efficacy of caplacizumab in a real-world setting, and identify predicting factors in iTTP-patients with regard to persistent autoimmune activity, therapy guidance and risk of complications. The rational is to develop new treatment algorithms that optimize overall patient outcome and reduce treatment cost.
