News Release Details

Canalevia would be first and only FDA-approved plant-based medicine for 50,000-plus dogs that suffer from diarrhea during chemotherapy

SAN FRANCISCO, CA / ACCESSWIRE / May 28, 2020 / Jaguar Health, Inc. (NASDAQ:JAGX) ("Jaguar" or the "Company") announced today that it has submitted to the U.S. Food and Drug Administration's Center for Veterinary Medicine (CVM) what the Company expects is the final major regulatory filing to support approval of its oral plant-based drug candidate Canalevia^™ (crofelemer delayed-release tablets) to treat chemotherapy-induced diarrhea (CID) in dogs.

According to current estimates, more than 230,000 dogs in the U.S. receive chemotherapy treatment for various cancers each year, and roughly one in four will experience diarrhea as a side effect of treatment. There currently is no FDA-approved anti-secretory prescription product to manage this debilitating diarrhea in dogs.

The filing consists of an updated version of the Target Animal Safety technical section of Jaguar's application for conditional approval of Canalevia for CID under the Minor Use/Minor Species (MU/MS) section of The Minor Use and Minor Species Animal Health Act of 2004.

"With this filing, which includes new administrative details, we are confident that CVM will deem our Target Animal Safety technical section Complete," said Dr. Michael Guy, DVM, Ph.D., Jaguar's vice president of preclinical and nonclinical studies.

As previously announced, the technical section contains data from a 2017 safety study indicating that the NOAEL (no-observed-adverse-effect level) of Canalevia in dogs is approximately six times greater than previously demonstrated, and that Canalevia also is safe for use in puppies as young as 12 weeks of age.

In addition to CID, Jaguar also is seeking conditional approval to market Canalevia for exercise-induced diarrhea (EID) in dogs. "We are leveraging many of the same major technical sections from our CID submission for the proposed EID indication," Dr. Guy said. "We expect that Canalevia could be available under conditional approval to treat both CID and EID in the first half of 2021."

"Jaguar is now one important step closer to having our first approved medicine for use in animals," said Jaguar president and chief executive officer Lisa Conte. "We believe Canalevia will be an important treatment option for the 50,000 dogs that suffer from CID each year. And once CID is under control, dogs may better tolerate their chemotherapy."

Jaguar's wholly owned subsidiary, Napo Pharmaceuticals, Inc. ("Napo"), currently markets Mytesi^®, another form of crofelemer, 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.

Napo is pursuing the development of Mytesi to treat cancer therapy-related diarrhea in humans. Conte said that dogs undergoing chemotherapy are an important predictive model for crofelemer's mechanism of action in humans experiencing diarrhea as a result of their cancer treatment.

As previously announced, the CVM has confirmed the completeness of Jaguar's Reasonable Expectation of Effectiveness technical section for CID under MU/MS, as well as the CMC (Chemistry, Manufacturing and Controls) and Environmental Impact technical sections of the Company's applications for conditional approval of Canalevia for both CID and EID.

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.
