Kindred Biosciences Announces Positive Results from Pilot Field Efficacy Study of its IL-4/IL-13 SINK Molecule Being Developed for the Treatment of Atopic Dermatitis in Dogs

San Francisco, California (March 24, 2020) – Kindred Biosciences, Inc. (NASDAQ: KIN), a biopharmaceutical company focused on saving and improving the lives of pets, today announced positive results from its pilot field efficacy study of KIND-025, a canine fusion protein targeting interleukin-4 (IL-4) and interleukin-13 (IL-13), for the treatment of atopic dermatitis in dogs.

The study was a randomized, blinded, placebo-controlled pilot effectiveness study that enrolled 26 client-owned dogs diagnosed with atopic dermatitis to assess the efficacy, safety, and pharmacokinetic profile of KIND-025. A single dose of KIND-025 or placebo was administered on day 0, and the severity of pruritus (Pruritic Visual Analog Scale [PVAS score]) and atopic dermatitis (Canine Atopic Dermatitis Extent and Severity Index-4 [CADESI-4 score]) were assessed at day 0 and weeks 1, 2, 3 and 4. 

Treatment success for individual dogs at each visit was defined as a 50% or higher reduction from baseline in CADESI-4 or PVAS scores. Higher success rate was observed in the KIND-025 group over the placebo group from week 1 through week 4. Positive efficacy signals were also detected with other endpoints including 20mm or higher reduction from baseline in PVAS score.

“These positive results mark KindredBio’s eighth positive pilot study in a row, half of which relate to canine dermatitis. We are very pleased that the overall response rate for the treated group was approximately twice the response rate for the placebo group at most timepoints,” stated Richard Chin, Chief Executive Officer of KindredBio. “Although this was a small study and therefore not powered to show a statistical difference, the response rate was promising. By targeting the inflammation pathway that underlies canine atopic dermatitis and other allergic diseases, this approach treats the disease rather than just the symptoms.”

There is strong demand for new biological treatments for pruritic dogs, with 70% of veterinarians, and a higher percentage of dermatologists, expressing a need for alternatives to current therapies, according to market research conducted by KindredBio. Atopic dermatitis is the leading reason owners take their dog to the veterinarian.

The IL-4 and IL-13 pathways are key drivers of the inflammation that underlies atopic dermatitis and other allergic diseases. Overproduction of cytokines, including IL-4 and IL-13, has been implicated in allergic skin disease, particularly atopic dermatitis. KindredBio’s IL-4/13 SINK molecule binds to both IL-4 and IL-13 circulating in the blood and inhibits their interactions with their respective receptors, thereby modifying the clinical signs associated with atopic dermatitis.
