@DrFraser - just saw this.
Mount Sinai invites Principal Investigators to participate in the upcoming XPRIZE Healthspan 2025 clinical trial, a landmark initiative to quantify and optimize biological aging through immune, muscle, and cognitive outcomes.
Objective
To characterize the immunodynamic effects of widely used longevity interventions, including Spermidine, Rapamycin, Metformin, and GLP-1 agonists.
The study will generate real-world evidence on how these interventions modulate aging trajectories, while accelerating the transition from anecdote to evidence in longevity medicine.
Primary Outcomes
Validated Healthspan Improvement defined by personalized response thresholds across three key systems:
- Muscle Function: endurance capacity (peak VO₂ ), lower body power, muscle mass (D₃-creatine dilution )
- Cognitive Function : executive function, processing speed, working memory
- Immune Function: ex vivo naïve immune response to novel stimuli, immune cell composition (IMM-AGE signature )
