Exploratory study evaluating effects of crofelemer on gut microbiome

SAN FRANCISCO, CA / ACCESSWIRE / August 23, 2021 / Napo Pharmaceuticals, the wholly-owned subsidiary of Jaguar Health, Inc. (NASDAQ:JAGX) today announced that an abstract associated with an exploratory clinical study on the effect of crofelemer (Mytesi^®) on the gastrointestinal microbiome in people living with HIV/AIDS (PLWHA) has been submitted for consideration for presentation at IDWeek 2021, which takes place virtually from September 29 to October 3.

Mytesi (crofelemer) is an antidiarrheal drug indicated for the symptomatic relief of noninfectious diarrhea in adult patients with HIV/AIDS on antiretroviral therapy (ART). Changes in gut microbiota of PLWHA on ART may contribute to HIV-1 related gut inflammation. This study evaluated the effects of crofelemer on the microbiota of PLWHA and HIV-negative subjects following one month of oral dosing, to test whether crofelemer's physiological mechanism of action in the gut lumen may indirectly affect the microbiota of PLWHA.

IDWeek is the joint annual meeting of the Infectious Diseases Society of America (IDSA), Society for Healthcare Epidemiology of America (SHEA), the HIV Medical Association (HIVMA), the Pediatric Infectious Diseases Society (PIDS), and the Society of Infectious Diseases Pharmacists (SIDP). Additional information IDWeek 2021 can be found on the IDWeek website: https://idweek.org.

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%).

See full Prescribing Information 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.
