Castor EDC
Castor EDC (also known as Castor CDMS) is a cloud-based electronic data capture (EDC) and clinical data management platform for clinical trials and other medical research. It supports participant (record) management, case report form (CRF) data collection, electronic patient-reported outcomes (ePRO) surveys, randomization, and study data export. The Castor public REST API lets you read and write study structure, records, and clinical data points programmatically.
