Kindred Biosciences Announces Positive Results from Pilot Effectiveness Study of its Fully Caninized IL-31 Antibody for the Treatment of Atopic Dermatitis in Dogs and Issuance of U.S. Patent

  • Statistically significant reduction in pruritus versus placebo was achieved across all dose groups.
  • Canine atopic dermatitis is a large and growing market, and KindredBio has a broad portfolio of biologics in development to treat this condition.

San Francisco, CA (October 30, 2018) — Kindred Biosciences, Inc. (NASDAQ: KIN), a commercial-stage biopharmaceutical company focused on saving and improving the lives of pets, today announced positive topline results from its pilot effectiveness study of KIND-016, a fully caninized, high-affinity monoclonal antibody targeting interleukin-31 (IL-31), for the treatment of atopic dermatitis in dogs. Atopic dermatitis is the leading reason owners take their dog to the veterinarian, and the current market size is over $500 million annually and growing rapidly.

In addition, KindredBio announced that the U.S. Patent and Trademark Office has issued a patent (Patent No. 10,093,731) for KindredBio’s anti-IL31 antibody.

The study was a randomized, blinded, placebo-controlled, pilot laboratory study that enrolled 32 dogs to assess the effectiveness of KIND-016 at three doses. A single dose of KIND-016 was administered on day 0 and itching was induced at weeks 1, 2, 3, 4, 6, and 8 with an injection of canine IL-31.

KindredBio’s IL-31 antibody resulted in statistically significant reductions in pruritus (p<0.0001 to p<0.05) across all dose groups and was sustained for 6 to 8 weeks, with a clear dose response. The reduction in the itching score was as high as 86.1%. Based on a preliminary review of the safety data, the drug appears to be well tolerated.

“We are very pleased with the unequivocally positive results from this study, as well as the recently-issued patent. Our goal is to develop best-in-class therapies for atopic dermatitis, and this is a major step toward that,” stated Richard Chin, CEO of KindredBio. “Canine atopic dermatitis is an attractive market, with some products now achieving annual sales of hundreds of millions of dollars. We believe our fully caninized, high-affinity, IL-31 antibody is well positioned to become an important therapeutic in the space. Furthermore, these positive results validate the broad portfolio of additional biologics we have for this disease, as well as for other serious unmet medical needs, positioning KindredBio to be a leader in companion animal biologics.”
