Jaguar Health Subsidiary Napo Pharmaceuticals Announces Activation by FDA of Investigational New Drug (IND) Application for NP-300, a Novel Drug Candidate for the Symptomatic Relief and Treatment of Diarrhea from Cholera and Other Pathogens

SAN FRANCISCO, CA / ACCESSWIRE / September 29, 2022 / Napo Pharmaceuticals, Inc. ("Napo"), the wholly-owned subsidiary of Jaguar Health, Inc. (NASDAQ:JAGX) ("Jaguar" or the "Company") today announced the activation by the U.S. Food and Drug Administration (FDA) of the Investigational New Drug (IND) application for Napo's NP-300, a 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.

"We were very pleased to hear from the FDA that they have completed their review of our IND application for NP-300 and concluded that Napo may proceed with its proposed phase I clinical trial for the drug. Following the completion of the phase I trial, the Company will be positioned to initiate the next stage of our clinical development program for cholera-related diarrhea when our development team has the requisite resources and bandwidth to initiate the additional required trials," said Lisa Conte, Jaguar's president and CEO. "We are grateful for the partial financial support from the National Institute of Allergy and Infectious Diseases (NIAID) to support the NP-300 preclinical program."

Cholera is an acute diarrheal illness caused by infection of the intestine with the bacterium Vibrio cholerae. Although cholera is an orphan indication in the United States, 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 of 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 United States. 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 botanical 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.

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 ("TDPRV") 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.
