Elamipretide to improve physical function and healthy aging
Official title: Open-Label, Single-Arm Phase 2a Pilot Study to Evaluate the Safety and Tolerability of a Daily Subcutaneous Dose of Elamipretide in Older Adults
Run by University of Washington · NCT07275424 · Data updated 2026-11-12
This study will try daily elamipretide injections for four weeks to see if the drug is safe and improves mobility, thinking, and blood inflammation markers in older adults with lower physical function.

Is this trial a fit for you?
✓Likely a good fit
Ideal candidates are ambulatory adults aged 65–80 with lower VO2peak (≤37.3 ml/kg/min for men, ≤25.7 ml/kg/min for women), who can self-administer or have a caregiver for injections, speak English, and are not in a regular exercise program.
✕Probably not a fit
People younger than 65 or older than 80, those who already follow a regular exercise routine, those taking excluded supplements or medications, or those with serious comorbidities may not receive benefit from this small, short-duration study.

What this trial studies
This Phase 2a, open-label, single-arm study will enroll about 30 ambulatory older adults (65–80 years) with lower aerobic capacity. Participants will self-administer daily subcutaneous elamipretide for four weeks with baseline and post-intervention clinic visits, a midpoint phone check, and a two-week follow-up after the last injection. The primary objective is to measure safety and tolerability, while secondary endpoints examine changes in blood inflammatory biomarkers and standardized cognitive and mobility tests. The trial is conducted at the University of Washington following GCP and FDA-aligned procedures.
Why it matters
Potential benefit: If successful, elamipretide could improve mobility and cognitive performance and lower inflammatory biomarkers in older adults, supporting larger trials.
How similar studies have gone: Elamipretide has shown promise in preclinical work and small clinical studies targeting mitochondrial function, but clinical findings have been mixed and its application to healthy aging remains relatively novel.
