News Release Details

SAN FRANCISCO, CALIFORNIA / ACCESS Newswire / January 2, 2026 / Jaguar Health, Inc. (NASDAQ:JAGX) ("Jaguar") today announced that it received notice from the U.S. Food and Drug Administration's Center for Veterinary Medicine (CVM) on January 1, 2026 that the company has been awarded a $240,000 grant. Canalevia-CA1 is currently conditionally approved for chemotherapy-induced diarrhea (CID) in dogs. The grant will support Jaguar's ongoing study for the treatment of CID in dogs.

"As announced on December 10, 2025, the FDA granted renewal of the conditional approval for Canalevia-CA1 for a fifth and final year, through December 21, 2026, for the treatment of CID in dogs. In order to receive a full veterinary drug approval for the indication of CID, Jaguar must complete and file a successful effectiveness study," said Dr. Michael Guy, D.V.M., M.S., Ph.D., Jaguar's Vice President of Preclinical and Nonclinical Studies.

Dogs undergoing chemotherapy are an important predictive model for the mechanism of action in humans experiencing diarrhea due to cancer treatment. Many cancer treatment agents provided to dogs are human drugs, or have the same mechanism of action as human cancer drugs, and these agents and mechanisms of action often have meaningful rates of diarrhea in dogs and humans.

A report by the American Veterinary Medical Foundation concluded that there were approximately 90 million dogs in the U.S. in 2024, of which Jaguar estimates more than 11 million suffer from general diarrhea each year. Data from the European Pet Food Industry Federation concluded that there were approximately 104 million dogs in Europe in 2022.

Canalevia is not an antibiotic drug. The overuse and misuse of antibiotics, both in humans and animals, contribute to the development of bacteria that are resistant to antibiotics.

Diarrhea is one of the most common reasons dogs are seen by general practice veterinarians and is the second most common reason for visits to veterinary emergency hospitals, yet there is currently no FDA-approved drug to treat general, non-infectious diarrhea in dogs. Devastating diarrhea-related dehydration can occur rapidly for the animal, and the lack of easy access to outdoor facilities is a significant problem for families living in urban settings with dogs.

About Chemotherapy-induced Diarrhea (CID) in Dogs

According to the American Veterinary Medical Association, approximately 1 in 4 dogs will at some stage in their life develop cancer. Nearly half of dogs over 10 will develop cancer.¹ According to the National Cancer Institute at the National Institutes of Health, roughly 6 million new cancer diagnoses are made in dogs yearly in the US.

Due to the increasing number of chemotherapeutic agents, chemotherapy is fast becoming the most widely used cancer treatment in veterinary medicine. Studies have found the incidence of CID to be one of the three most prevalent side effects in dogs undergoing cancer treatment,² and managing side-effects such as diarrhea can be important to maintain successful cancer treatment. More than half of the US veterinarians who responded to a Jaguar-sponsored survey reported that CID interferes with their canine patients' chemotherapy treatment plans, indicating an unmet need for an effective product for the treatment of CID.
