Napo Pharmaceuticals, a Jaguar Health Family Company, Submits Funding Application to National Institute of Allergy and Infectious Diseases for Development of NP-300 Drug Candidate for Cholera-Related Diarrhea

Cholera is an acute diarrheal illness caused by infection of the intestine with the bacterium Vibrio cholerae

Jaguar intends to pursue a Tropical Disease Priority Review Voucher, under FDA’s financial incentive program, to develop NP-300 for this indication

SAN FRANCISCO, CA / ACCESSWIRE / September 12, 2023 / Napo Pharmaceuticals (Napo), a Jaguar Health (NASDAQ:JAGX) (Jaguar) family company, today announced that it has submitted a grant application to the National Institute of Allergy and Infectious Diseases (NIAID) for funding to support Napo’s Phase I study 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.

“I am very pleased that this grant application has been filed,” said Michael K. Guy, DVM, PhD, Napo’s Vice President of Preclinical and Nonclinical Studies. “We look forward to the day when NP-300 may be available to provide symptomatic relief and treatment of dehydrating diarrhea from acute infections such as that with cholera.”

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 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 Napo’s crofelemer drug product, 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.

Upon completion of the requisite development activities to support the New Drug Application (NDA) and subsequent approval of NP-300 by the FDA for the symptomatic relief and treatment of diarrhea from cholera, the Company intends to pursue a Tropical Disease Priority Review Voucher, under the FDA’s financial incentive program, to develop NP-300 for this indication. Priority review vouchers are transferable, and in past transactions by other companies have sold for values ranging from $67 million to $350 million, which provides for a potential immediate return on investment upon approval of NP-300 for the cholera-related diarrhea indication.
