As contemporary society faces the growing challenge of aging populations worldwide, the quest to understand, quantify, and ultimately enhance human healthspan has never been more urgent. Central to this mission is the concept of intrinsic capacity (IC), an integrative measure combining physical and mental abilities that serve as the bedrock for independence and resilience as individuals age. Despite its critical importance, intrinsic capacity remains inadequately captured in clinical and research settings due to the lack of affordable, validated tools—a gap that has impeded progress in aging science and therapeutic interventions.
Addressing this unmet need, an interdisciplinary consortium known as the THRIVE team, spearheaded by Dr. Michael Snyder, Director of the Center for Genomics and Personalized Medicine at Stanford University, alongside collaborators at the Buck Institute for Research on Aging and the Methuselah Foundation, has launched an ambitious initiative backed by a $34.5 million award from the Advanced Research Projects Agency for Health (ARPA-H). This program represents a pioneering effort to develop robust, science-driven metrics for predicting long-term health outcomes associated with aging, integrating cutting-edge genomic, biomarker, and digital health data.
The cornerstone of THRIVE’s endeavor is the creation of the PROSPR Intrinsic Capacity score, a predictive model designed to forecast a spectrum of 20-year health outcomes, including mortality, multimorbidity incidence, hospitalization risk, and functional decline. Unlike traditional clinical metrics, PROSPR ingeniously melds multidimensional data streams—from comprehensive health surveys and physical functional evaluations to continuous wearables monitoring via Whoop devices, coupled with blood-based molecular biomarkers—leveraging millions of longitudinal datapoints gathered from diverse populations. This integrative approach promises unprecedented granularity and predictive power over individual health trajectories.
In parallel with model development, the THRIVE consortium is committed to translating these advances into a streamlined, user-friendly at-home assessment platform. This kit, envisaged to retail below $100, aims to democratize access to high-fidelity intrinsic capacity measurement, enabling scalable population-level health monitoring without the barriers of expensive clinical visits or proprietary diagnostics. The potential clinical and public health implications are profound, offering a dynamic tool for early detection and intervention, shifting paradigms from reactive disease treatment to proactive functional preservation.
Andrew Brack, ARPA-H Program Manager and architect of the PROSPR initiative, highlights the transformative potential of this approach. He emphasizes that the absence of reliable, actionable surrogate endpoints has stymied clinical trials targeting aging, traditionally requiring multi-decade studies. By establishing PROSPR as a short-term, reliable, and modifiable biomarker for aging-related health transitions, THRIVE lays the groundwork for accelerating therapeutic evaluation timelines dramatically—from decades to mere years—ushering in a new era of geroscience-enabled clinical research.
Dane Gobel, Co-Founder of the Methuselah Foundation, articulates a visionary perspective that aging, once dismissed as an immutable process, is now quantifiable and treatable through this diagnostic infrastructure. The PROSPR platform transcends the notion of a mere study by aiming to construct an operational framework to standardize and validate aging biology endpoints with the same rigor as conventional clinical markers such as blood pressure and cholesterol. This scientific paradigm shift holds promise for revolutionizing regulatory standards, clinical decision-making, and personalized prevention strategies.
Fundamental validation of the PROSPR score will be pursued via large-scale, decentralized observational and lifestyle intervention trials. Conducted in collaboration with YMCA and utilizing OpenCures’ clinical trial platform, these studies will encompass over a thousand diverse participants representing the heterogeneous U.S. population. By monitoring the effects of modifiable lifestyle factors—diet, exercise regimens, sleep quality, stress reduction, and social engagement—on intrinsic capacity, researchers aim to substantiate that functional aging decline can be measurably attenuated through accessible behavioral modifications, thereby substantiating IC as a viable therapeutic target.
Dr. David Furman, Bioinformatics Director at the Buck Institute, underscores the groundbreaking integration of molecular and functional phenotyping at scale in this initiative. By converging bioinformatics prowess, computational biology, and clinical expertise, THRIVE anticipates generating next-generation aging predictors and therapeutic targets. This systems biology approach recognizes age-associated intrinsic capacity decline not merely as a consequence of chronic disease but as a treatable, diagnostically trackable condition—redefining the conceptual landscape of aging medicine.
In complement, clinical lead Dr. Brianna Stubbs emphasizes PROSPR’s capacity to shift aging research from academic silos into community settings. Through decentralized clinical trials and YMCA-based interventions, the program aims to deliver scalable, community-embedded strategies that safeguard resilience and extend healthspan across diverse populations. By standardizing intrinsic capacity measurement with clinical rigor, PROSPR provides a critical tool not merely for research but for real-world application in preventive medicine and public health frameworks.
This moonshot program exemplifies a novel nexus of gerontology and geroscience, poised to create diagnostic standards akin to those long established for cardiovascular and metabolic risk factors. As intrinsic capacity is quantified with increasing precision, interventions can be tailored, optimized, and monitored in near real-time, marking a decisive leap forward toward personalized longevity medicine. The profound societal implications of extending functional years of life portend a future where aging no longer dictates decline but becomes a modifiable, manageable facet of human health.
In light of demographic trends, with aging populations exerting escalating socio-economic pressures globally, the successful deployment of THRIVE’s innovations could alleviate substantial healthcare burdens. By facilitating earlier interventions and mitigating the onset and severity of age-related diseases, this program contributes not only to individual well-being but also to systemic sustainability, potentially transforming healthcare delivery models and policy priorities toward resilience and prevention.
Ultimately, the THRIVE initiative represents an unprecedented collaboration among academia, non-profit foundations, technology providers, and community organizations, harnessing the convergence of big data analytics, wearable technologies, and molecular biomarker science. This integrative, multidisciplinary approach exemplifies the future direction of biomedical research, where holistic understanding and actionable insights coalesce to redefine the boundaries of human health and aging.
