Validation & Intervention Testing for Aging, Longevity and Healthspan (VITAL-H)
Validation & Intervention Testing for Aging, Longevity and Healthspan (VITAL-H)
The study aims to address the gap between lifespan and healthspan (years of life free of age-related diseases and disabilities) by testing whether 2 approved U.S Food and Drug Administration (FDA) medications, dapagliflozin and semaglutide, can help people stay healthier as they age and delay the age-related functional decline. The study will test these medications over 36 months of treatment plus 6 months of observational follow up to see if they can safely maintain health and function during aging and eventually support their use for extending healthspan.
This study is being done because there are limited ways to slow down the age-related health and functional decline, and few reliable ways to measure early changes in healthspan in humans. The 2 study drugs have shown promising results in laboratory and early human studies, but more evidence is needed.

Gedetailleerde beschrijving
Phase 2b, hybrid-decentralized, double-blind, randomized placebo-controlled trial to evaluate the independent effects of dapagliflozin, oral semaglutide, and placebo on functional decline in healthy adults aged 60-75 years. 1200 individuals will be randomized to parallel intervention arms and followed for 36 months of intervention plus 6 months post-intervention follow-up to evaluate changes in locomotion (continuous short physical performance battery - primary outcome), vitality (peak oxygen uptake during exercise, VO2 peak - secondary outcome). Exploratory outcomes will include changes in body composition, individual components of intrinsic capacity (IC) across multiple functional geroscience-based domains, and overall intrinsic capacity. This hybrid-decentralized clinical trial integrates wearable technology, deep phenotyping, and biomarker analyses to evaluate if the proposed therapies demonstrate meaningful differences in functional healthy longevity outcomes.
