Castor EDC overview

What is Castor EDC?

Castor is a leading Electronic Data Capture (EDC) system, designed to help researchers capture, integrate, and manage data seamlessly from any source. With Castor, you can build and launch studies within hours using pre-built templates and effortlessly integrate EMR/EHR, patient-reported outcomes (ePRO, eCOA), clinical, and device data (eCRF, eSource) into a single, centralized platform. 90% of studies in Castor pass UAT in under four weeks, far exceeding industry benchmarks.

Castor’s self-service, no-code platform makes study setup easy, offering features such as drag-and-drop eCRF creation, ePRO for patient surveys, automated randomization, real-time monitoring, seamless data import/export, HL7 FHIR-based EHR integration, and API connectivity. Advanced compliance and security measures include audit trails, granular user management, and adherence to ISO27001, ISO9001, HIPAA, GCP, 21 CFR, and GDPR standards.

Built for speed, flexibility, and compliance, Castor accelerates clinical research by enabling faster deployments, seamless data interoperability, and enhanced patient engagement—all in a modern, cloud-native environment.

To see what individual users think of Castor EDC's price and value, check out the review snippets below.

“The option to come back and add more answers to a multiple-choice question while still working on the form (this is not a change to an answer but merely an addition of data). If I complete a form and later modify the contents of more than one question, the messages should be specific to each change rather than general for the entire page, since the reasons for each change might be different.”
