As scientists push the boundaries of longevity research, new developments in canine anti-aging treatments could offer exciting possibilities for human health. A San Francisco-based biotech firm, Loyal, is set to launch a pioneering anti-aging drug for dogs in 2025, with hopes that it could extend canine lifespans—and perhaps, one day, help humans live longer, healthier lives.
Loyal’s drug, named LOY-002, will be a beef-flavored daily pill designed to counteract age-related decline in dogs. According to The Guardian, the drug works by reducing insulin levels associated with aging and fighting frailty, potentially adding at least one more healthy year to a dog’s life. Celine Halioua, the founder and CEO of Loyal, emphasized that the goal is not immortality but rather to slow the aging process and promote overall health. “We’re not making immortal dogs,” Halioua said, adding that the pill could slow the rate of aging by promoting healthier aging.
At the same time, another significant research project, the Dog Aging Project, is investigating the effects of rapamycin, a drug commonly used in human organ transplants. The University of Washington study is exploring the potential of low doses of rapamycin to extend dog lifespans by up to three years, while also improving heart and cognitive function. Daniel Promislow, biogerontologist and co-director of the project, described the research as “light years ahead” of human-focused studies, comparing it to the equivalent of a 40-year-long human study.
Interestingly, the findings from this research could offer valuable insights into women’s health. According to Kate Creevy, the chief veterinary officer for the Dog Aging Project, comparing spayed and unspayed dogs could offer a unique understanding of health issues related to menopause and aging in women.
However, experts like Jamie Justice, an adjunct professor at Wake Forest University School of Medicine, caution that translating these animal studies to human treatments will not be straightforward. Without a universally accepted biomarker of aging in humans, applying findings from dogs to human medicine presents significant challenges.
The results of these promising studies are expected to take another four to five years, but the potential benefits—both for dogs and humans—are vast. If successful, these groundbreaking treatments could open new frontiers in anti-aging research, potentially offering humans the chance to extend healthspan and lifespan as well.
