The Fort Worth Press - Jaguar Health Secures an Additional $3 Million Payment from Future Pak for Mytesi and Canalevia-CA1

SAN FRANCISCO, CA / ACCESS Newswire / March 3, 2026 / Jaguar Health, Inc. (NASDAQ:JAGX) today announced that its wholly-owned subsidiary Napo Pharmaceuticals, Inc. (collectively, with Jaguar Health, Inc., "Jaguar") has received a $3 million payment from Future Pak, LLC ("Future Pak") following termination by Jaguar of the buy-back provision of the U.S. licensing agreement Jaguar entered in January 2026 with a Future Pak affiliate, which allows Future Pak to continue to commercialize Mytesi beyond five years. Jaguar will continue to manufacture Mytesi and Canalevia-CA1 for Future Pak.

Under the terms of the agreement, Future Pak became the exclusive marketer for Mytesi (crofelemer), Jaguar's FDA-approved novel prescription drug for the symptomatic relief of noninfectious diarrhea in adult patients with HIV/AIDS on antiretroviral therapy, and Canalevia-CA1, Jaguar's crofelemer prescription drug for the treatment of chemotherapy-induced diarrhea in dogs. Jaguar was provided with $16 million of non-dilutive capital in January 2026 upon closing of the agreement with Future Pak, with an additional $2 million due to Jaguar upon completion of post-closing conditions. Per the terms of the agreement, Jaguar also has the opportunity to receive up to $20 million in milestone payments and other future payments.

"As announced, the agreement has a buy-back option that provides Jaguar with the unilateral right to repurchase all of the licensed rights from Future Pak starting five years after the agreement effective date, provided that certain regulatory milestones are met," said Lisa Conte, Jaguar's founder, president, and CEO. "Per the terms of the agreement, Jaguar receives $3 million by terminating the buy-back option. In the interest of generating additional non-dilutive capital for Jaguar, I am pleased to announce that we have received the $3 million payment from Future Pak."

"Our agreement with Future Pak is fully aligned with our strategy to concentrate Jaguar's crofelemer development efforts on human rare-disease indications, particularly intestinal failure, where we continue to advance business development discussions with additional potential partners," Conte said.

Crofelemer continues to advance as a potential treatment for rare forms of intestinal failure, including intestinal failure due to short bowel syndrome (SBS-IF) and microvillus inclusion disease (MVID). Multiple investigator-initiated and company-sponsored studies of crofelemer are ongoing in the U.S., the European Union and the United Arab Emirates, with initial proof-of-concept data showing significant reductions in parenteral support (PS) requirements in pediatric MVID and SBS-IF patients.

Jaguar's intestinal failure program is expected to continue to provide clinical proof-of-concept milestones, and the company is targeting Breakthrough Therapy designation for crofelemer for the indication of MVID, with a planned filing of an NDA (New Drug Application) with the U.S. Food and Drug Administration for this indication in the first half of 2027.

Intestinal failure is a debilitating condition that often requires patients to receive life-sustaining fluids, electrolytes and nutrients through intravenous administration, which consists of total parenteral nutrition (TPN) with supplemental intravenous fluids, which together constitute PS. Many intestinal failure patients require PS up to 7 days a week, and sometimes for 20 hours or more per day. While crucial for intestinal failure patients, PS is associated with significant toxicities to patients, similar to some toxicities associated with chemotherapy, often causing serious health problems including infections, metabolic complications, and liver and kidney function problems. These symptoms may emerge at any time in intestinal failure patients and often become life-threatening.
