Loyal has completed its first clinical study.
The Healthspan study successfully recruited over 500 dogs from across the United States, exceeding our target enrollment.
The aim of the Healthspan study was to better understand various aging and aging-related biomarkers and how they may relate to dog size and age.
Dogs were evaluated by specially trained veterinarians at 11 locations across the country, from traditional private veterinary hospitals to university medical centers, and in our novel pop-up style mobile study sites.
The data gathered in the Healthspan study will advance the field’s understanding of aging in dogs and help develop treatments that reduce the impact of aging on our dogs. We will publish the results in a peer-reviewed journal; preliminary analysis is estimated to be completed by Q4’21.
