The Accrual to Clinical Trials (ACT) Network is a real-time platform to explore the feasibility for clinical studies across the NCATS Clinical and Translational Science Award consortium. ACT helps researchers design and complete clinical studies and is secure, HIPAA-compliant and IRB-approved.

ACT was developed collaboratively by members of NCATS’ Clinical and Translational Science Award consortium, with funding from the NIH National Center for Advancing Translational Sciences.

Tufts CTSI Affiliated clinical researchers and study teams can now query nearly 40 million patient records through the Accrual to Clinical Trials (ACT) Network for discovery, exploration, and validation of patient cohorts for investigator-initiated multi-site or single-site clinical trials.
