SAN FRANCISCO, CA / ACCESSWIRE / August 9, 2023 / Napo Pharmaceuticals Inc. (Napo), a Jaguar Health, Inc. (NASDAQ:JAGX) family company, today announced that it has submitted a Stage 1 funding application to the Biomedical Advanced Research and Development Authority (BARDA) for development of NP-300, the company's novel drug product candidate for the symptomatic relief and treatment of moderate-to-severe diarrhea, with or without concomitant antimicrobial therapy, from bacterial, viral and parasitic infections including Vibrio cholerae, the bacterium that causes cholera. BARDA, part of the Administration for Strategic Preparedness and Response at the U.S. Department of Health and Human Services, supports advanced research and development of medical countermeasures and is a component of the Public Health Emergency Medical Countermeasures Enterprise (PHEMCE).

"We are seeking funding from BARDA to help fund the Phase 1, Phase 2, and Phase 3 studies for development of NP-300 with an eye toward increasing American preparedness and response time in the event of exposure to cholera due to bioterrorism or the advancement of cholera into U.S. territories due to global warming," said Steve King, PhD, Jaguar's Chief Sustainable Supply, Ethnobotanical Research, and IP Officer. "If BARDA expresses interest in this initiative, the next step would be for Napo to proceed to Stage 2 of the application process, which would involve submitting a full proposal to BARDA."

As announced, Napo's Investigational New Drug (IND) application for NP-300 was activated by the U.S. Food and Drug Administration (FDA) in September 2022. In support of the IND application filing, the company received partial financial support for certain IND-enabling preclinical toxicity studies from the National Institute of Allergy and Infectious Diseases (NIAID). NIAID is part of the National Institutes of Health.

Although cholera is an orphan indication in the US, it is estimated that, worldwide, 1.3 to 4 million cholera cases and 21,000 to 143,000 cholera-related deaths occur each year, according to the Centers for Disease Control and Prevention of the U.S. Department of Health & Human Services. Approximately one in 10 infected persons will have severe disease characterized by profuse watery diarrhea, vomiting, and leg cramps. In these people, rapid loss of body fluids leads to dehydration and shock. Without treatment, death can occur within hours. Cholera is now endemic in many countries outside the U.S. The largest cholera outbreak in recorded history occurred recently in Yemen. According to Oxfam, the number of cholera cases in Yemen in 2019 was the second largest ever recorded in a country in a single year, surpassed only by the numbers in Yemen in 2017.

NP-300 is a novel oral drug product that is sustainably derived from the Croton lechleri tree, the same source as that for crofelemer, and is planned to be developed under the FDA's Botanical Guidance. As stated on the FDA's website, crofelemer is currently one of only two drugs that have been approved under the FDA's Botanical Guidance definition of a botanical drug product.
