Research that starts with the TMA community.
Patients, clinicians, and researchers contribute to a multicenter learning network designed to improve what is known about TMA and support future studies.
Participation becomes infrastructure for discovery.
USTMA studies bring together longitudinal clinical information, biospecimens, specialist expertise, and multicenter collaboration. Public website metrics are shown only in aggregate.
Every participant adds to what the TMA community can learn.
P200 is a multicenter registry designed to gather standardized longitudinal clinical information across participating institutions. The public view below uses aggregate data only.
Research powered by a connected TMA community.
P200 brings longitudinal clinical information together across the USTMA network so investigators can ask better questions and build better studies.
