SAN FRANCISCO, CA / ACCESSWIRE / December 6, 2021 / Jaguar Health, Inc. (NASDAQ:JAGX) today announced it is hosting a closed satellite event on December 9, 2021 at SABCS in San Antonio, Texas.

The event will also include a presentation by Darlene Horton, MD, Napo Pharmaceuticals Chief Medical Officer, on the company's ongoing OnTarget Pivotal Phase 3 trial.

OnTarget is the company's pivotal Phase 3 clinical trial of crofelemer for prophylaxis of diarrhea in adult cancer patients receiving targeted therapy. The study is enrolling adult patients with solid tumors, including breast cancer patients, requiring targeted therapies with or without cycle chemotherapy. OnTarget is sponsored by Napo Pharmaceuticals, Jaguar Health's wholly owned subsidiary.

HALT-D Results Poster Presentation

In addition, data on crofelemer from the investigator-initiated HALT-D trial will be presented by a third-party on Friday, December 10th from 7:00 - 8:30 a.m. CT at SABCS. The HALT-D trial, which is separate from the OnTarget trial, evaluated crofelemer for preventing chemotherapy-induced diarrhea (CID) in HER2-positive breast cancer patients being treated with trastuzumab, pertuzumab and a taxane. The virtual poster will be available starting at 7:00 a.m. CT as well.

About Cancer Therapy-related Diarrhea

A significant proportion of patients undergoing cancer therapy experience diarrhea, and diarrhea has the potential to cause dehydration, potential infections, and non-adherence to treatment in this population. Novel "targeted cancer therapy" agents, such as epidermal growth factor receptor (EGFR) antibodies and tyrosine kinase inhibitors (TKIs), with or without cycle chemotherapy agents, may cause increased electrolyte and fluid content in the gut lumen, which results in passage of loose/watery stools (i.e., diarrhea). Diarrhea has been reported as one of the most common side effects of TKIs and may result in cancer therapy drug holidays or reductions from therapeutic dose, potentially impacting patient outcome. Diarrhea is also a common side effect of some approved CDK 4/6 inhibitors.

About Mytesi®

Mytesi® (crofelemer delayed release tablets) 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. Infectious etiologies of diarrhea should be ruled out by a physician 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%).
