Castor is a leading cloud-based clinical data platform designed to democratize research and streamline the complexities of decentralized, hybrid, and traditional clinical trials. Trusted by academic institutions, biotech, and pharmaceutical companies worldwide, Castor enables researchers to capture high-quality data and accelerate study timelines through a modular, human-centered ecosystem.   Our plug-and-play platform seamlessly integrates the four critical components of modern clinical research: Electronic Data Capture (EDC): A user-friendly, rapid-deployment EDC system that allows researchers to build and launch studies in a matter of clicks, not months, ensuring robust data integrity and security.   eConsent: A flexible electronic consent solution that simplifies patient enrollment and improves comprehension, supporting remote and on-site recruitment strategies to maximize participation.   eCOA (Electronic Clinical Outcome Assessment): Intuitive tools for capturing Patient-Reported Outcomes (PROs) directly from participants, enhancing engagement and retention while reducing the burden of data entry. Real-World Evidence (RWE): Advanced capabilities to capture and unify real-world data from wearables, medical devices, and EHRs, providing a holistic view of patient health beyond the clinical setting.   By prioritizing a "participant-first" approach, Castor improves the trial experience for both researchers and patients. From rapid study build and enrollment to final analysis, Castor delivers the speed, scalability, and compliance needed to drive successful outcomes in the evolving landscape of clinical research.
