The National Institutes of Health (NIH) is offering a funding opportunity for cooperative agreements to establish a Clinical Coordinating Center (CCC) for multi-site, investigator-initiated clinical trials focused on the effects of natural products, such as botanicals and dietary supplements. Applicants are required to develop a comprehensive scientific and operational plan for the clinical trial, including project management, participant recruitment, and performance milestones, while also submitting a companion Data Coordinating Center (DCC) application. This initiative aims to generate robust clinical data to inform integrative health approaches and public health strategies, with applications opening on January 20, 2025, and closing on July 14, 2026.
