FDA Denies Petition Seeking Accelerated Aging Therapies
FDA has denied an 8/17/2025 petition filed by Age Reversal Unity seeking a regulatory framework for conducting expedited clinical trials of aging-related therapeutics within a nine-month timeframe. The agency’s denial letter says, “FDA does believe that issuing such a one-size-fits-all framework is scientifically appropriate or in the best interests of public health.” It notes there are many different types of diseases and conditions that are more prevalent in the older adult population, and the appropriate clinical trial endpoints for the diseases and conditions will vary depending on factors such as the disease or condition under study, investigational drug, patient population, clinical setting, phase of drug development, and disease severity.
Likewise, FDA says, the appropriate duration of a clinical trial is case-specific and considers the time necessary to evaluate the clinical endpoint of interest and the ability to collect data necessary to evaluate the investigational drug’s safety.
The letter says FDA has determined that no new regulatory framework or guidance is necessary for sponsors to use efficient clinical trial designs or expedited programs.
