A Full Analysis of the Study Data with Scoring of Squamous and Glandular Ulcers is Expected to be Available in January

SAN FRANCISCO--(BUSINESS WIRE)--Jaguar Animal Health, Inc. (NASDAQ:JAGX) (“Jaguar”), an animal health company focused on developing and commercializing first-in-class gastrointestinal products for companion and production animals, foals, and high value horses, today issued a summary of racing data for horses taking part in the Company’s recently completed dose determination study of the target commercial paste formulation of Equilevia (formerly referred to as SB-300), the Company’s drug product candidate for treatment of Equine Gastric Ulcer Syndrome (“EGUS”).

“We believe independent analysis of the endoscopy data from this study is highly important—both to ensure consistency of grading and to determine the most clinically relevant endpoint scoring system for our planned field trial”

Equileviais a pharmaceutical formulation of a standardized botanical extract. The randomized, blinded, controlled, multisite dose determination study enrolled 121 racehorses two years of age or older. All enrolled horses were diagnosed with glandular and squamous gastric ulcers. The primary objective of the study was to select the minimally effective dose of Equileviafor the treatment of equine gastric ulcers in a future pivotal field study.

Horses on treatment with Equilevia had higher average winnings as a percent of purse in races during the study treatment period compared with the period in which they raced prior to the study. Horses on placebo or on the positive control (Merial’s GASTROGARD® product) had a reduction in their average winnings as a percent of purse during the study treatment period compared with the period in which they raced prior to the study.

Additionally, horses on treatment with Equilevia had higher average total dollar winnings in races during the study period compared with the period in which they raced prior to the study. However, horses on placebo had a reduction in total earnings in races during the study period compared with the period in which they raced prior to the study, whereas horses on GASTROGARD® had essentially no change in their earnings in races compared with the period in which they raced prior to the study.

When analyzing data according to whether or not a horse finished a race in the top 3 or in the top 5, there was also an improvement seen for horses treated with Equilevia during the study treatment period compared with the period in which they raced prior to the study. Horses treated with placebo, however, had a reduction in frequency of finishing in the top 3 or in the top 5 in the study period compared with the period in which they raced prior to the study.

No statistically significant comparisons were generated for the aforementioned exploratory analyses.

“Racing results in horses treated with Equilevia during our dose determination study are of interest because ulcers are a particular problem in equine athletes,” stated Lisa Conte, Jaguar’s president and CEO. “This study was not powered for this type of result nor would we expect to have such a result listed in a product label.”

During the dose determination study, endoscopies were obtained at baseline, prior to the start of treatment, on day 15 and finally on day 29 of treatment. The equine veterinarians performing the endoscopies were blinded to the treatment assignment, and the Company is also blinded to these data at this time. A full analysis of the dose determination study data with scoring of squamous and glandular ulcers is awaiting an independent, blinded review by an equine veterinarian experienced in gastric ulcer disease, and is expected to be available this coming January. Review will include comparisons of more than one scoring system in order to identify the best means of assessing clinical improvement of both squamous and glandular lesions for a proposed primary endpoint. Jaguar’s intention is to identify a scoring system that most appropriately demonstrates clinical change in both squamous and glandular ulcers, and the Company plans to seek concurrence from the FDA's Center for Veterinary Medicine (“CVM”) with regard to the selected scoring system.

“We believe independent analysis of the endoscopy data from this study is highly important—both to ensure consistency of grading and to determine the most clinically relevant endpoint scoring system for our planned field trial,” commented Dr. Roger Waltzman, Jaguar’s Chief Scientific Officer. “Ultimately, this analysis will be presented to CVM with the intention of developing a pivotal field study with concurrence in the protocol design and statistical analysis.”

As Jaguar announced this past January, topline results from its proof-of-concept study to evaluate the safety and effectiveness of Equileviaindicate that 78 to 89% of horses treated with Equilevia (depending on dose) had resolution or improvement of glandular ulcers as soon as 14 days during treatment. As Jaguar announced this past February, further analysis of the results of the proof-of-concept study indicates that Equileviadid not alter gastric pH during the 28-day trial, or for 7 days after therapy. A treatment for EGUS that does not alter gastric pH is important because maintaining low gastric pH may be helpful for digestion, for gut immunity and first line defense against pathogens, for the absorption of vitamins and minerals, and for potentially additional downstream effects. As Jaguar announced in May of this year, standard drug testing in race horses that received Equileviadid not detect any substances commonly disallowed by horse racing authorities.

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. 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.1

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, foals, and high value horses. Canalevia is Jaguar’s lead prescription drug product candidate, intended for the treatment of various forms of diarrhea in dogs. Equilevia (formerly referred to as SB-300) is Jaguar’s prescription drug product candidate for the treatment of gastrointestinal ulcers in horses. Canalevia and Equilevia contain ingredients 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, formulations of Equilevia in horses, and Canalevia for cats and dogs.
