Jaguar Animal Health Initiates University Pilot Safety Study to Evaluate Use of Crofelemer for the Treatment of Diarrhea Associated with Acute Colitis 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, announced today that it has initiated a pilot safety study in conjunction with Louisiana State University to evaluate the use of crofelemer for treatment of diarrhea associated with acute colitis in horses. Crofelemer is an active pharmaceutical ingredient isolated and purified from the Croton lechleri tree, which is sustainably harvested.

Colitis is defined as inflammation of the large bowel, and the condition can affect adult horses as well as foals. Acute colitis can cause sudden, massive fluid loss and severe electrolyte imbalances that can result in death in a matter of hours. Acute colitis often occurs when Salmonella and Clostridium difficile, bacteria that are normally present in the gut, are activated by stress, or when the bacteria Neorickettsia risticii is ingested, causing Potomac Horse Fever, which has been studied as a secretory type of diarrhea by third parties. Stress (e.g., shipping, changes in daily routines, illness, hospitalization, racing), recent diet changes, recent antimicrobial administration, and non-steroidal anti-inflammatory drug therapy can also put horses at risk for acute colitis.

"Colitis can affect thousands of horses in the United States each year, and treatment of acute colitis with crofelemer in high-value racing and performance horses represents a premium specialty market opportunity that aligns with our continued focus on gut health across multiple species," stated Lisa Conte, Jaguar's president and CEO. "We intend to seek MUMS—minor use in a major species—designation for an indication in horses."

In this pilot safety study, three horses will be treated with four consecutive, three-day cycles of escalating dose levels of a crofelemer paste administered orally twice or four times per day. Clinical observations and adverse events will be evaluated for dose-limiting toxicity after each dose level.
