The Department of Health and Human Services, through the National Institutes of Health's Advanced Research Projects Agency for Health (ARPA-H), is soliciting proposals for the DRAFT Innovative Solutions Opening (ISO) under the PROactive Solutions for Prolonging Resilience (PROSPR) program. This initiative aims to extend the healthspan of Americans by developing interventions that address the underlying causes of age-related health decline, including establishing a predictive Intrinsic Capacity score and repurposing FDA-approved drugs. The program emphasizes a structured, multidisciplinary approach over a five-year timeline, focusing on key milestones such as in-home assessment technologies and decentralized clinical trials to enhance accessibility in health interventions. Interested proposers can find more information and submit inquiries via the PROSPR email box at PROSPR@arpa-h.gov, with a final ISO expected to be published at a later date.
