ACCELERATE Patient Registry

Enrolling With ACCELERATE

ACCELERATE is a registry created and maintained by the University of Pennsylvania that collects medical data about people suffering from Castleman disease. The information is then shared with researchers and doctors, who study the data and uncover patterns found in patients, with the goal of improving treatments and treatment plans.
