Jaguar Animal Health Reports Topline Findings For Its Proof-Of-Concept Study To Evaluate The Safety And Effectiveness Of An Investigational New Animal Drug Candidate For The Treatment Of Gastrointestinal Ulcers In Horses

SAN FRANCISCO--(BUSINESS WIRE)--Jaguar Animal Health, Inc. (NASDAQ: JAGX) (“Jaguar” or the “Company”), an animal health company focused on developing and commercializing first-in-class gastrointestinal products for companion and production animals, and high-value horses, announced positive topline results today from its proof-of-concept study to evaluate the safety and effectiveness of its investigational new animal drug currently referred to as SB-300. SB-300 is a pharmaceutical formulation of a standardized botanical extract from the Croton lechleri tree, which is sustainably harvested, for the treatment of gastrointestinal ulcers in horses.

In this prospective, blinded, randomized, negative controlled study, Standardbred or Thoroughbred racehorses were randomized to one of three groups (10 horses per group) and treated for 28 days: horses in the placebo group received water-filled syringes every 6 hours; those in the TRT5 group received 5 grams of SB-300 divided into 2 doses per day; and those in the TRT40 group received 40 grams of SB-300 divided into 4 doses per day. Strict enrollment criteria required patients to have both squamous (non-glandular) and glandular gastric ulcerations. All horses were examined by gastroscopy (stomach endoscope) by blinded equine investigators on Day 0 (prior to treatment; baseline), and on Day 14 (mid-study), Day 28 (last day of treatment) and Day 35 (7 days after last treatment). Treatment-related adverse events were not observed.

With respect to glandular ulcerations, a statistically significantly greater number of horses in both the TRT40 (89%) and the TRT5 (78%) group had an improvement or a resolution of glandular ulcerations, compared with the placebo (25%) group as soon as Day 14. By Day 35, all of the SB-300 treated horses had experienced improvement or resolution, whereas 25% of horses in the placebo group still had not improved or resolved during the study.

With respect to squamous ulcerations, a non-statistically significant dose-dependent effect was observed with 40% and 33% of horses achieving an improvement or a resolution by Day 14 in the TRT40 and TRT5 groups, respectively, compared with 11% of placebo horses. By Day 35, numerically more horses in the TRT40 (60%) and TRT5 (55%) groups had achieved an improvement or a resolution compared with 33% of placebo horses.

Jaguar will be releasing additional findings from this study after further analysis of the data.

As Jaguar stated on November 5^th of last year in a press release announcing the initiation of this study, stall confinement, stress, intermittent feeding, intense exercise and administration of non-steroidal anti-inflammatories are factors that may lead to gastric ulcers in horses¹ and, frequently, in performance equine athletes. Horses with gastric ulcers may perform poorly, which makes this condition an economic as well as health problem within the horse industry².

According to a third-party 2005 study, as many as 55% of performance horses have both colonic and gastric ulcers, and 97% of performance horses have either a gastric (87%) or a colonic (63%) ulcer.³ Data from the American Horse Council states that there are currently 9.2 million horses in the U.S., a population that includes 844,531 race horses, more than 2.7 million show horses, and more than 3.9 million recreational horses. Data from the Food and Agriculture Organization of the United Nations indicate that there were approximately 5.7 million horses in Europe in 2013 and nearly 60 million horses in 2013 worldwide.

About Jaguar Animal Health, Inc.

Jaguar Animal Health, Inc. is an animal health company focused on developing and commercializing first-in-class gastrointestinal products for companion and production animals. Canalevia^™ is Jaguar’s lead prescription drug product candidate for the treatment of various forms of diarrhea in dogs. Canalevia^™ is a canine-specific formulation of crofelemer, an active pharmaceutical ingredient isolated and purified from the Croton lechleri tree, which is sustainably harvested. Neonorm^™ Calf and Neonorm^™ Foal are the Company’s lead non-prescription products. Neonorm^™ is a standardized botanical extract derived from the Croton lechleri tree. Canalevia^™ and Neonorm^™ are distinct products that act at the same last step in a physiological pathway generally present in mammals. Jaguar has nine active investigational new animal drug applications, or INADs, filed with the FDA and intends to develop species-specific formulations of Neonorm^™ in six additional target species, and formulations of Canalevia^™ for cats, horses and dogs.
