Kindred Biosciences Announces Positive Results from Pivotal Efficacy Study of Parvovirus Monoclonal Antibody

- Study demonstrated 100% efficacy in prevention of parvovirus infection in prophylactic pivotal study of KIND-030

SAN FRANCISCO, Sept. 16, 2020 /PRNewswire/ -- Kindred Biosciences, Inc. (NASDAQ: KIN), a biopharmaceutical company focused on saving and improving the lives of pets, today announced positive results from a pivotal efficacy study of KIND-030, a monoclonal antibody targeting canine parvovirus (CPV). The results showed 100% efficacy in the prevention of parvovirus, as well as a mortality benefit in the treated group.

In this randomized, blinded, placebo-controlled study, KIND-030 was administered to dogs as prophylactic therapy to prevent clinical signs of CPV infection. The primary objectives of the study were met. All of the placebo-control dogs developed parvovirus infection as predefined in the study protocol, while none of the KIND-030 treated dogs developed the disease. Furthermore, the parvovirus challenge resulted in 60% mortality rate in the control dogs compared to 0% mortality rate in the KIND-030 treated dogs.

KIND-030 is currently being pursued for two indications in dogs: prophylactic therapy to prevent clinical signs of canine parvovirus infection and treatment of established parvovirus infection. The pivotal efficacy study for the treatment indication and pivotal safety studies remain on track to be completed by year-end 2020, with approval expected by early 2021.

"We are very pleased with these positive study results, which for the first time provide hope to dogs exposed to this deadly disease," said KindredBio's Chief Executive Officer, Richard Chin, M.D. "Parvovirus represents a significant unmet medical need. We believe KIND-030 can transform the way parvovirus infections are treated and prevented."

CPV is the most significant and contagious viral cause of enteritis in dogs, especially puppies, with mortality rates reportedly as high as 91%. There are currently no Food and Drug Administration or United States Department of Agriculture (USDA) approved treatments for CPV, nor any other available treatment. Currently, owners spend up to thousands of dollars per puppy in supportive care for CPV, with average cost of $1,200.

KIND-030 binds to critical portions of the virus, preventing the virus from entering into cells.

Canine parvovirus typically affects unvaccinated puppies less than 6 months of age, but can occur in unvaccinated dogs of any age1. Veterinarians estimate that about half of the puppies they see infected with parvovirus have potentially exposed other puppies to the virus, and each puppy has on average the potential to expose five other puppies to the disease2. One study showed 64.5% of dogs entering a shelter had insufficient protective antibody titers against canine parvovirus3.

Banfield estimates that there are approximately 250,000 parvo cases in the U.S. each year, excluding emergency hospitals, shelters, specialty hospitals, or undiagnosed cases4.  Typically this number fluctuates slightly from year to year, but data from BluePearl, the national pet hospital network, recently noted a 70% increase in positive parvovirus cases and hospitalizations in their hospitals during the COVID-19 pandemic.

Regulatory approval and review timeline are subject to the typical risks inherent in such a process. The results stated in this press release have not been reviewed by the USDA Center for Veterinary Biologics.
