How to Join Senolytic Clinical Trials: A Practical Guide

Expert Summary

Multiple senolytic clinical trials are actively recruiting in the US and internationally as of 2026. Trial participation provides free access to physician-supervised senolytic treatment, comprehensive safety monitoring, and contribution to science — at no cost to participants. The primary barrier is meeting eligibility criteria, which typically include age (≥65), specific health characteristics, and geographic proximity to a trial site.

Key Facts

• Finding trials: ClinicalTrials.gov — search "senolytics aging", "fisetin senolytic", "dasatinib aging", or "senescent cells". Filter by: "Recruiting", "Observational or Interventional", your country. ResearchMatch.org also connects volunteers to registered trials.
• Common eligibility criteria: Most aging senolytic trials require: age ≥60–65, specific health conditions (frailty, DKD, Alzheimer's, IPF), ability to give informed consent, proximity to trial site (or travel provision for some trials), and specific exclusion criteria (active cancer, severe kidney disease).
• What participation involves: Typically: screening visit (labs, ECG, physical exam), baseline visit (biopsies for some trials, blood tests), 1–4 treatment visits (receiving study drug or placebo), follow-up visits at 4, 8, 12 weeks post-treatment.
• Benefits of participation: Free senolytic treatment (either active drug or placebo), comprehensive medical monitoring (labs, ECG, physical assessments), access to cutting-edge interventions, and direct contribution to the evidence base that will help future patients.
• WISDOM trial: Evaluating spermidine for frailty prevention (NCT05271747). Multiple European sites. Relevant for individuals over 65 with physical frailty indicators.
• ALSENLITE: D+Q for Alzheimer's disease (NCT05686200). Multiple US sites. For individuals with mild-to-moderate Alzheimer's disease.
• PEARL extension studies: Ongoing fisetin aging studies at Mayo Clinic. Check NCT02555878 for open enrollment phases.

Frequently Asked Questions

Can I continue taking supplement senolytics while in a clinical trial?

Always disclose all supplements to trial investigators. Some trials exclude participants taking senolytics or require a washout period. Others allow continuation of supplements. Never conceal supplement use from trial staff.

What if I'm randomized to placebo?

Placebo assignment is frustrating but provides essential scientific data. After trial completion, many trials offer open-label extension periods where all participants receive active treatment. Ask the trial team about post-trial access.
