Castor

Castor's Real-World Evidence (RWE) solution is a modern, end-to-end platform designed to simplify and accelerate RWE generation. Leveraging a modular, flexible technology stack, Castor enables sponsors to launch and scale RWE studies—including observational studies, registries, and Phase IV/post-marketing trials—in weeks, not months. Our platform seamlessly integrates real-world data (RWD) from existing sources like EHRs and claims data, while also facilitating compliant direct-to-patient (DTP) data collection via eConsent and ePRO/eCOA. With a proven track record across over 1,100 RWE projects, Castor boosts data quality, enhances patient engagement, and provides the high-quality evidence needed for critical regulatory, market access, and safety decisions.
