Jaguar Subsidiary Napo Pharmaceuticals Files CMC Supplement with FDA for Sample-Size Bottles of Mytesi, Napo’s FDA-Approved Human Drug, to Support Upcoming National Sample Campaign

SAN FRANCISCO--()--Jaguar Health, Inc. (NASDAQ: JAGX) (Jaguar), a natural-products pharmaceuticals company focused on developing and commercializing novel, sustainably-derived gastrointestinal products for both human prescription use and veterinary use on a global basis, announced today that its wholly-owned subsidiary, Napo Pharmaceuticals, Inc. (Napo), has filed a Chemistry, Manufacturing, and Controls (CMC) supplement with the U.S. Food & Drug Administration (FDA) for six-tablet bottles of Mytesi®, Napo’s FDA-approved human drug, in preparation for Napo’s planned national sample campaign.

Mytesi® is approved by the U.S. FDA for the symptomatic relief of noninfectious diarrhea in adults with HIV/AIDS on antiretroviral therapy. Jaguar and Napo are pursuing a follow-on indication for Mytesi® in chemotherapy-induced diarrhea (CID), an important supportive care indication for patients undergoing primary or adjuvant chemotherapy for cancer treatment. Mytesi® is also in development for rare disease indications for infants and children with congenital diarrheal disorders and short bowel syndrome (SBS); for irritable bowel syndrome (IBS) (Mytesi® has demonstrated benefit to IBS-D patients in published Phase 2 studies); for supportive care for inflammatory bowel disease (IBD); and as a second-generation anti-secretory agent for use in cholera patients. Mytesi® has received orphan-drug designation for SBS.

The planned sample bottles will contain enough Mytesi® tablets for three days of use. To implement the filing, Napo produced stability data in support of a one-year shelf life for the contents of the sample bottles.

As announced earlier this month, Napo significantly expanded the national salesforce for Mytesi® through the recent hire in key U.S. markets of six sales representatives experienced in the sale of drugs to HIV physicians and gastroenterologists. Napo’s new sales representatives are based in and will cover New York, Miami, Atlanta, Los Angeles, Houston, San Francisco and the surrounding regions. A dedicated Mytesi® salesperson has been based in the St. Louis/Chicago area since this past March. All of these regions are key markets for HIV-related drug sales.

“Chronic diarrhea remains a significant complaint of people living with HIV/AIDS, particularly those who are older and have lived the virus in their gut for over 10 years. This is a growing demographic of the HIV community, and Mytesi® is the only antidiarrheal studied in and U.S. FDA-approved for the symptomatic relief of noninfectious diarrhea in adults living with HIV/AIDS on antiretroviral therapy,” Pete Riojas, Napo’s national sales director for Mytesi®, stated. “Driving patient awareness about Mytesi® is one of our key goals, and we expect our planned sample program to be highly impactful in this regard.”

Mytesi® is currently covered by Medicaid in all 50 states. It is also currently covered on 100% of the top 10 commercial insurance plans, representing more than 245 million U.S. lives. Additionally, Napo operates a co-pay coupon to ensure that no participating patients have a Mytesi® co-pay greater than $25.

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.
