Canalevia^®-CA1 is the first and only treatment for CID in dogs to receive any type of approval from FDA

Jaguar Health, Inc. (NASDAQ:JAGX), under its Jaguar Animal Health tradename for the veterinary market, today announced that Canalevia-CA1 (crofelemer delayed-release tablets), the company's prescription drug product for the treatment of chemotherapy-induced diarrhea (CID) in dogs, is now available from multiple leading veterinary distributors in the U.S. Canalevia-CA1 received conditional approval from the FDA on December 21, 2021.

"We are very excited that Canalevia-CA1 is now available to veterinarians across the country," said Chip Whitlow, Sales & Marketing Director of the company's Animal Health Commercial Portfolio. "Canalevia-CA1 is an important prescription drug introduction for the veterinary community and the thousands of dogs experiencing CID. Canalevia-CA1 can help support the comfort and quality of life of dogs while being treated with chemotherapy, which may help keep them compliant with their life-saving treatment."

Due to the increasing number of chemotherapeutic agents being adopted by veterinary oncologists and general practice veterinarians, chemotherapy is quickly becoming the most widely used oncology modality 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,¹ and managing side effects such as CID can be important to maintain successful cancer treatment. More than half of the U.S. veterinarians who responded to a recent 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.

Canalevia-CA1 is a tablet that can be given orally twice a day and can be used for home treatment of CID.

Jaguar Animal Health launched the www.canalevia.com website in December 2021. For veterinarians, the site provides Canalevia-CA1 prescribing information, data on the pharmacological properties and novel mechanism of action of the product's active pharmaceutical ingredient, crofelemer, and a listing of upcoming veterinary conferences the company plans to attend. For dog owners, the site provides an overview of CID and its negative effects on dogs undergoing chemotherapy.

Canalevia-CA1 is a formulation of crofelemer, an active pharmaceutical ingredient isolated and purified from the Croton lechleri tree. Canalevia-CA1 is currently conditionally approved by the FDA under application number 141-552.

FDA has established a "small number" threshold for minor use in each of the seven major species covered by the MUMS act.
