from Jaguar Health, Inc. (NASDAQ:JAGX)

Patient Enrollment Surpasses 90% in Jaguar Health's Pivotal Phase 3 OnTarget Trial of Crofelemer for Cancer Therapy-Related Diarrhea

Enrollment expected to complete in mid-Q2 2023

As of March 24, 2023, as previously announced, the Company's cash position was approximately $15.3 million

SAN FRANCISCO, CA / ACCESSWIRE / April 11, 2023 / Jaguar Health, Inc. (Nasdaq:JAGX) ("Jaguar" or the "Company") today announced that patient enrollment has surpassed 90% in the Company's pivotal Phase 3 OnTarget clinical trial of crofelemer for prophylaxis of diarrhea in adult cancer patients receiving targeted therapy with or without chemotherapy.

"Just the week before last - on March 27th - we announced that patient enrollment in OnTarget had reached approximately 80%, and we are very happy to report that enrollment in OnTarget is now already above 90%," said Lisa Conte, Jaguar's president and CEO. "Our efforts over the past year to expand the OnTarget trial to new U.S. and international sites - with trial sites now active in Eastern Europe - in both Georgia and the Republic of Serbia - as well as in Argentina and Taiwan - have significantly accelerated patient enrollment, and we now expect target trial enrollment of 256 patients to complete by mid-second quarter of 2023."

The Company's expectation is that the placebo controlled OnTarget trial will provide evidence that diarrhea associated with targeted cancer therapies is chronic, not acute, and impacts the patient's ability to remain on their cancer therapy regimens at proven doses for better outcomes. The OnTarget trial is evaluating the effectiveness of crofelemer's novel mechanism of action - the modulation of two chloride ion channels in the gastrointestinal tract - to mitigate or substantially reduce chronic cancer therapy-related diarrhea.

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.
