Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Because of the non-interventional nature of the study, there is no predefined treatment protocol. The patients will be treated according to the routine practices of the centers. In observational drug studies, the drug to be administered in treatment should be prescribed and patient's treatment should be started prior to study inclusion decision is made as a principle. The participating physician will continue to treat the patients according to their routine practices. Not only newly diagnosed patients, all aTTP patients within participated centers will be recruited and 12 months follow-up data will be collected. 21 hematology centers in Turkey will participate in this noninterventional observational study.
