SAN FRANCISCO--(BUSINESS WIRE)--

The merger of Jaguar Animal Health, Inc. and Napo Pharmaceuticals, Inc. (Napo) became effective today, July 31, 2017, at which point Jaguar Animal Health’s name changed to Jaguar Health, Inc. (Jaguar) and Napo began operating as a wholly-owned subsidiary of Jaguar focused on human health and the ongoing commercialization of Mytesi^®, which is approved by the U.S. FDA for the symptomatic relief of noninfectious diarrhea in adults with HIV/AIDS on antiretroviral therapy. Although Jaguar’s name has changed, the public company will continue to trade under the same Nasdaq ticker symbol: JAGX.

The terms of the merger include additional funding for the combined company, at $0.925 per share as disclosed in the definitive joint proxy statement/prospectus. As of today’s date, the combined company has approximately 66 million shares outstanding, and approximately 98 million shares outstanding on a fully diluted basis.

“We are thrilled that the merger of Jaguar and Napo has become effective. It is truly transformational for Jaguar Health to forward-integrate into an important revenue stream from Mytesi^®, for which we hold unencumbered global rights and are pursuing multiple follow-on indications for various chronic gastrointestinal disorders. We estimate the potential U.S. market for Mytesi^® to be approximately $100 million in gross annual sales, and anticipate that Mytesi^® will generate approximately $7.0 million in revenue by April 2018 for its current, FDA-approved specialty indication,” Lisa Conte, Jaguar's president and CEO, stated.

Jaguar Health is pursuing a follow-on indication for Mytesi^® in chemotherapy-induced diarrhea, an important supportive care indication for patients undergoing primary or adjuvant chemotherapy for cancer treatment. Mytesi^® is in development for orphan-drug indications for infants and children with congenital diarrheal disorders and short bowel syndrome; as a second-generation anti-secretory agent for use in cholera patients; and for supportive care for irritable bowel syndrome (IBS) and inflammatory bowel disease (IBD). Mytesi^® has demonstrated benefit to D-IBS patients in published Phase 2 studies.

Jaguar Health’s next expected veterinary product commercial launch will be for Equilevia^™, a personalized premium proprietary total gut health product for equine athletes, which will be non-prescription.

About Mytesi^®

Mytesi^® (crofelemer) is an antidiarrheal indicated for the symptomatic relief of noninfectious diarrhea in adult patients with HIV/AIDS on antiretroviral therapy (ART). Mytesi^® is not indicated for the treatment of infectious diarrhea. Rule out infectious etiologies of diarrhea before starting Mytesi^®. If infectious etiologies are not considered, there is a risk that patients with infectious etiologies will not receive the appropriate therapy and their disease may worsen. In clinical studies, the most common adverse reactions occurring at a rate greater than placebo were upper respiratory tract infection (5.7%), bronchitis (3.9%), cough (3.5%), flatulence (3.1%), and increased bilirubin (3.1%).

More information and complete Prescribing Information are available at Mytesi.com. Crofelemer, the active ingredient in Mytesi^®, is a botanical (plant-based) drug extracted and purified from the red bark sap of the medicinal Croton lechleri tree in the Amazon rainforest. Napo has established a sustainable harvesting program for crofelemer to ensure a high degree of quality and ecological integrity.
