Developing Longevity Drugs for Dogs
The development of longevity drugs for humans faces challenges related to time and money. However, these challenges are less severe in dogs, making them a suitable model for aging research. Loyal, a San Francisco-based startup valued at $425 million, is developing drugs to delay K9 aging and aims to have its first beef-flavored longevity pill on the market in 2026.
The Thesis of Aging and Aging Therapeutics
The core idea behind aging therapeutics is to target the mechanisms that cause deterioration and aging, which lead to diseases. By addressing these precursors, it's possible to keep individuals healthy for a longer period. Loyal is working on drugs to extend dog lifespan, focusing on two main categories:
- Big Dog Short Lifespan: Addressing the genetic drivers that cause big dogs to age faster and die sooner.
- Metabolic Decline: Targeting metabolic decline, which affects dogs of all sizes. Metabolism is likened to the engine of a car, which becomes less efficient with age, leading to decreased energy and age-related diseases. The goal is to keep the metabolism running efficiently and delay negative health consequences.
Validated Mechanisms Across Organisms
The drugs and mechanisms chosen by Loyal are well-validated across various organisms, including worms, yeast, and mice. These mechanisms are not specific to dogs but are foundational to how organisms have evolved to age. The individual aging trajectory of a dog is influenced by factors such as diet, genetics, and lifestyle. Therefore, it's crucial to find a biological mechanism that is not affected by this variability and is fundamental to how life works.
Clinical Trials and Data Collection
Loyal is conducting a large clinical trial involving approximately 1300 dogs across the US. The trial is blinded, meaning that neither the veterinarians nor the dog owners know whether the dogs are receiving the drug or a placebo. The dogs will be followed for four to five years to track their aging process, diseases, and changes in blood levels. The goal is to quantify the lifespan and health span benefits of the drug compared to the placebo.
The trial is decentralized to capture the diversity of the average dog population, including geographic and socioeconomic diversity. This approach ensures that the results are applicable to a wide range of dogs, not just those in specific demographics. The data collected will provide valuable insights into how dogs age and the causes of age-related diseases, advancing the field of geriatrics in veterinary medicine.
Addressing Skepticism and Misconceptions
The field of longevity research is sometimes met with skepticism due to the presence of scientifically questionable information. However, when the science behind lifespan extension is explained, skepticism often turns to excitement. Selene Hollywood, Loyal's CEO, emphasizes the importance of distinguishing between legitimate science and marketing hype.
Selene Hollywood's Background and Motivation
Selene Hollywood's upbringing exposed her to the vulnerability of the average person to health issues, which motivated her to work on developing drugs for aging. Despite initial skepticism from biotech professionals, she pursued her vision of getting a drug FDA-approved for lifespan extension.
Hollywood's background includes a PhD in the health economics of gene therapy from Oxford University and experience at the Longevity Fund, a venture capital firm. These experiences shaped her understanding of drug development and the importance of economic incentives for preventative care.
Serendipitous Founding of Loyal
The idea for Loyal came about serendipitously when Hollywood realized that no one was developing an aging drug for dogs. This led her to focus on dog longevity as a way to introduce the concept of longevity to the general public and demonstrate the legitimacy of the science.
Greg Rosen, an early investor, convinced Hollywood that dog longevity was a viable business opportunity and that she could be a successful founder and CEO.
Building Loyal and Navigating Challenges
The early years of Loyal involved defining the company's identity and iterating on its drug development strategy. The company faced challenges related to the complexities of drug development and regulatory requirements. Loyal is committed to conducting rigorous science and pursuing FDA approval for its drugs, rather than taking the easier route of developing supplements.
FDA Approval and Future Ambitions
Loyal has obtained FDA agreement that a drug can be approved for lifespan extension and has earned reasonable expectation of efficacy approvals for two of its drugs. The company is closer than ever to bringing its drugs to market.
Hollywood's ambitions extend beyond dogs, as she believes that developing drugs to extend dog lifespan is one of the best ways to develop drugs to extend human lifespan. The knowledge gained from dog longevity research will provide valuable insights into human aging and health.
Conclusion
Loyal is pioneering the field of dog longevity with the goal of extending the healthy lifespan of dogs and advancing the science of aging. The company's commitment to rigorous science, FDA approval, and decentralized clinical trials sets it apart from others in the field. The success of Loyal could pave the way for future advancements in human longevity.
