Conditional approval extended through December 2026 for the treatment of CID in dogs

CID confirmatory effectiveness trial expected to conclude in February 2026, ahead of FDA’s June deadline – 51 dogs enrolled to date; ~49 more expected
SAN FRANCISCO, CA / ACCESS Newswire / December 10, 2025 / Jaguar Health, Inc. (NASDAQ:JAGX) today announced that the U.S. Food and Drug Administration (FDA) has granted renewal of the conditional approval for Canalevia-CA1 (crofelemer delayed-release tablets). Canalevia-CA1, the company’s prescription drug for the treatment of chemotherapy-induced diarrhea (CID) in dogs, is available from multiple leading veterinary distributors in the U.S., including Chewy. The renewal of conditional approval is in effect until December 21, 2026.
“Canalevia-CA1 is an important prescription drug for the veterinary community and the thousands of dogs experiencing CID. We’re very pleased about this conditional approval renewal, which, per FDA regulations, is for the fifth and final allowable year of conditional approval for Canalevia-CA1 for the CID indication in dogs. When an animal drug receives conditional approval, the FDA requires that a confirmatory trial take place within 5 years to provide the substantial evidence of effectiveness required for full approval of the drug for the indication,” said Dr. Michael Guy, D.V.M., M.S., Ph.D., Jaguar’s Vice President of Preclinical and Nonclinical Studies. “As announced, our full effectiveness study of Canalevia-CA1 for the treatment of CID in dogs is underway, and this recent conditional approval renewal was granted because we were able to demonstrate active progress toward generating this required data.”
“Diarrhea is a highly neglected and unmet medical need in dogs and people undergoing cancer treatment,” said Lisa Conte, Jaguar’s president and CEO. “Jaguar is deeply committed to supporting the quality of life of people and animals undergoing cancer treatment.”
About Conditional Approval and Full Approval
Canalevia-CA1 initially received conditional approval in December 2021 from the FDA for the treatment of CID in dogs. FDA’s conditional approval allows a drug company to legally promote, advertise and sell the animal drug for the labeled uses before proving it meets the “substantial evidence” standard of effectiveness for full approval. The conditional approval is valid for one year, with up to four annual renewals, for a total of five years of conditional approval. To receive a renewal from the FDA, the company must show active progress toward proving “substantial evidence of effectiveness” for full approval. After collecting the remaining effectiveness data, the company then applies to the FDA for full approval. The FDA reviews the application and, if appropriate, fully approves the drug.
About Canalevia®-CA1
Canalevia-CA1 contains crofelemer, Jaguar’s novel, oral plant-based drug sustainably harvested from the Croton lechleri tree, that modulates chloride channels in the gastrointestinal tract to reduce diarrhea. Importantly, 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. Canalevia-CA1, currently conditionally approved by the FDA under application number 141-552, is a tablet that can be given orally twice a day for up to three days and can be used for home treatment of CID in 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 patients’ chemotherapy treatment plans, indicating an unmet need for an effective product for the treatment of CID.
Important Safety Information About Canalevia®-CA1

Prior to using Canalevia-CA1, rule out infectious etiologies of diarrhea. Canalevia-CA1 is a conditionally approved drug indicated for the treatment of chemotherapy-induced diarrhea in dogs.
