Jaguar Health Completes Final Major Regulatory Filing for Conditional New Animal Drug Approval of Canalevia (Crofelemer) to Treat Exercise-induced Diarrhea in Dogs

Canalevia^™ would be first and only FDA-approved plant-based medicine for working dogs that suffer from diarrhea

SAN FRANCISCO, CA / ACCESSWIRE / February 10, 2022 / Jaguar Health, Inc. (NASDAQ:JAGX), under its Jaguar Animal Health tradename for the veterinary market, today announced that it has completed filing of the final major regulatory section with the U.S. Food and Drug Administration's ("FDA") Center for Veterinary Medicine (CVM) to support conditional new animal drug approval of the company's oral plant-based drug candidate Canalevia (crofelemer delayed-release tablets) to treat exercise-induced diarrhea (EID) in dogs.

In December of 2021, Jaguar Animal Health received conditional approval from the FDA for Canalevia^™-CA1 for chemotherapy-induced diarrhea (CID) in dogs.

"We are leveraging many of the same major technical sections from our successful CID submission for the proposed EID indication," said Dr. Michael Guy, DVM, MS, Ph.D., Jaguar Health's vice president of preclinical and nonclinical studies. "We expect that Canalevia could receive FDA conditional approval, under the name Canalevia^™-CA2, to treat EID in dogs in the fourth quarter of 2022."

Working dogs, including search and rescue, military, and sled dogs, often suffer diarrhea as a result of engaging in long periods of intense, off-leash exercise. "Elite athletes of all species tend to have more diarrhea than their healthy though more sedentary counterparts, which can interfere with peak physical performance," said Dr. Michael Davis, DVM, Ph.D., DACVIM, DACVSMR, a veterinary physiologist and board-certified specialist in veterinary internal medicine and veterinary sports medicine at Oklahoma State University, where he conducts research on animal exercise physiology and performance. "There is a significant need in the world of working dogs for a safe and effective medicine that can reduce the incidence and severity of exercise-induced diarrhea without affecting performance."

Jaguar Health's wholly owned subsidiary, Napo Pharmaceuticals ("Napo"), currently markets another form of crofelemer, Mytesi^®, the only non-opioid oral plant-based medicine approved by the FDA for the treatment of noninfectious diarrhea in adult patients with HIV/AIDS on antiretroviral therapy. Crofelemer comes from the Croton lechleri tree, which is responsibly and sustainably harvested in South America.

Minor Use/Minor Species (MUMS) section of The Minor Use and Minor Species (MUMS) Animal Health Act of 2004

MUMS designation is modeled on the orphan-drug designation for human drug development and offers possible financial incentives to encourage MUMS drug development, such as the availability of grants to help with the cost of developing the MUMS drug and a longer period of marketing exclusivity. The purpose of the MUMS Act is to encourage development and availability of animal drugs intended as a minor use in a major species (dogs, cats, cattle, horses, chickens, turkeys, and pigs) to treat diseases which occur infrequently or in limited geographic areas, and to encourage development and availability of animal drugs for use in minor species (defined as all animals other than humans that are not one of the seven major species).

FDA has established a "small number" threshold for minor use in each of the seven major species covered by the MUMS act. The small number threshold is currently 70,000 for dogs, representing the largest number of dogs that can be affected by a disease or condition over the course of a year and still have the use qualify as a minor use.

Canalevia-CA1 has received MUMS designation for CID in dogs, and Jaguar Health believes Canalevia meets the requirements for MUMS designation for the planned EID indication in dogs.

The company estimates that 5,000 to 15,000 dogs in the U.S. experience EID annually.

As previously announced, the CVM has already confirmed the completeness of three of the four major required technical sections of Jaguar Animal Health's application for conditional approval of Canalevia for EID. This filing completes the submission process for the fourth major technical section, which was initiated during the pandemic in 2020.

About Mytesi^®

Mytesi (crofelemer) is an antidiarrheal indicated for the symptomatic relief of noninfectious diarrhea in adult patients with HIV/AIDS on antiretroviral therapy (ART). Mytesi is not indicated for the treatment of infectious diarrhea. Rule out infectious etiologies of diarrhea before starting Mytesi. If infectious etiologies are not considered, there is a risk that patients with infectious etiologies will not receive the appropriate therapy and their disease may worsen. In clinical studies, the most common adverse reactions occurring at a rate greater than placebo were upper respiratory tract infection (5.7%), bronchitis (3.9%), cough (3.5%), flatulence (3.1%), and increased bilirubin (3.1%).

See full Prescribing Information at Mytesi.com. Crofelemer, the active ingredient in Mytesi, is a botanical (plant-based) drug extracted and purified from the red bark sap of the medicinal Croton lechleri tree in the Amazon Rainforest. Napo has established a sustainable harvesting program for crofelemer to ensure a high degree of quality and ecological integrity.
