News Release Details

By prescription only, Canalevia^™-CA1 is a canine-specific formulation of crofelemer, Jaguar's novel, oral plant-based product sustainably harvested from the Croton lechleri tree

SAN FRANCISCO, CA / ACCESSWIRE / December 21, 2021 / Jaguar Health, Inc. (NASDAQ:JAGX) today announced it received conditional approval to market Canalevia^™-CA1 (crofelemer delayed-release tablets), Jaguar's oral plant-based prescription drug for the treatment of chemotherapy-induced diarrhea (CID) in dogs. This is the first and only product indicated for the treatment of chemotherapy-induced diarrhea (CID) in dogs to receive any type of approval from FDA.

According to the American Veterinary Medical Association, approximately 1 in 4 dogs will, at some stage in their life, develop a tumor, and almost 50% of dogs over age 10 will develop cancer.¹ According to the National Cancer Institute, which is part of the National Institutes of Health, roughly 6 million new cancer diagnoses are made in dogs each year in the U.S.

Due to the increasing number of chemotherapeutic treatments being adopted by veterinarians and veterinary oncologists, 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 treatment², and managing side-effects such as diarrhea is imperative 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 patient's chemotherapy treatment plan, indicating an unmet need for an effective product for CID.

Canalevia-CA1 will be marketed as a prescription drug product under the company's Jaguar Animal Health tradename. Jaguar will be sharing more details surrounding the commercialization plan for Canalevia-CA1 in early January 2022.

"We are thrilled to be filling a large gap in the canine cancer care field by providing relief to thousands of dogs and pet owners across the country who thankfully can benefit greatly from advances in canine cancer treatments, yet also have to manage the burden of diarrhea as a common side effect," said Lisa Conte, Jaguar's President and CEO and parent of two Jack Russell Terriers. "In a third-party survey of dog and cat owners, the majority of participants (58%) indicated that they believed that the benefits of chemotherapy did not counterbalance the impact of the potentially negative side effects which animals may experience during treatment.³ Canalevia-CA1 provides another option to address the comfort of dogs undergoing chemotherapy and supports the dog's ability to maintain control, which is important for maintaining a comfortable living environment in the family household."

About Crofelemer

Crofelemer is a novel, oral plant-based medicine extracted and purified from the red bark sap, also referred to as "dragon's blood," of the medicinal Croton lechleri tree in the Amazon Rainforest. Jaguar Health's wholly owned subsidiary, Napo Pharmaceuticals, has established a sustainable harvesting program, under fair trade practices, for crofelemer to ensure a high degree of quality, ecological integrity, and support for Indigenous communities.

About Canalevia^™-CA1

Canalevia^™-CA1 (crofelemer delayed-release tablets) is the first and only oral plant-based prescription product that is FDA conditionally approved to treat chemotherapy-induced diarrhea (CID) in dogs. Canalevia^™-CA1 is a canine-specific 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. Conditional approval allows for commercialization of the product while Jaguar continues to collect the substantial evidence of effectiveness required for a full approval. Jaguar has received Minor Use in a Major Species (MUMS) designation from the FDA for Canalevia-CA1 to treat CID in dogs. 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.
