The National Institutes of Health (NIH), through the National Institute on Drug Abuse (NIDA), is inviting applications for the development of Clinical Outcome Assessments (COA) aimed at enhancing therapeutic development for Opioid and Stimulant Use Disorders (OUD and SUD). Applicants are required to submit a COA development plan that encompasses two phases: an initial two-year UG3 phase followed by a potential three-year UH3 phase, contingent upon the successful achievement of operational milestones. This funding opportunity underscores the urgent need for validated COAs in the treatment of substance use disorders and emphasizes the importance of inclusivity in research through the mandatory inclusion of a Plan for Enhancing Diverse Perspectives (PEDP). Up to $2.5 million is available for three to five awards, with a maximum budget of $500,000 per year. The submission period opens on June 9, 2024, and closes on July 10, 2024.
