Castor

Cloud-native EDC platform for building, running, and collecting data for clinical and medical device studies.

Visit Castor Alternatives

Castor is a cloud-native electronic data capture (EDC) platform combined with electronic clinical outcome assessment (eCOA), electronic informed consent (eConsent), and real-world evidence data collection in one system. Its self-service, no-code study builder lets research teams design case report forms, configure randomization, and launch a study without heavy IT involvement, which distinguishes it from the more implementation-heavy enterprise EDC systems from larger vendors. Castor supports investigator-initiated studies, academic research, and sponsor-run trials across pharma, medical device, and diagnostics, and states compliance with ISO 27001, ISO 9001, HIPAA, GCP, 21 CFR Part 11, and GDPR. As with Medidata, Veeva Vault CDMS, and Oracle Clinical One, Castor is the system of record that captures trial data, rather than an analytics layer applied after the fact. Founded in Amsterdam in 2012, it now serves sponsors globally.
