Two Investigator-Initiated Responder Analysis Trials of Jaguar Health’s Crofelemer Show Significant Positive Results for Chronic Refractory Diarrhea in IBS-D: Data Accepted for Presentation at American College of Gastroenterology 2024 Annual Meeting
It is estimated that 10-15% of people in the United States have IBS
SAN FRANCISCO, CA / ACCESSWIRE / August 1, 2024 / Jaguar Health, Inc. (NASDAQ:JAGX) (“Jaguar”) family company Napo Pharmaceuticals (“Napo”) today announced that the results of two independent investigator-initiated studies of crofelemer, Napo’s novel, plant-based oral prescription drug, showed a benefit in patients with chronic refractory diarrhea and have been accepted for poster presentations at the American College of Gastroenterology Annual Scientific Meeting, which takes place October 25-30, 2024 at the Pennsylvania Convention Center in Philadelphia.
“We are very excited that crofelemer continues to demonstrate clinical robustness in responder analysis trials for multiple gastroenterological conditions – including functional diarrhea and chronic idiopathic diarrhea. We are inspired to address the unmet needs, unmet symptom management, and patient comfort in these populations, which are often considered subgroups of diarrhea-predominant irritable bowel syndrome (IBS-D),” commented Lisa Conte, President and CEO of Jaguar. Crofelemer has been the subject of two previously presented Phase 2 trials in IBS-D.
Investigator-Initiated Study in Functional Diarrhea
Crofelemer significantly decreased stool consistency and abdominal pain without significant side effects, including constipation, in this small crossover study of 18 patients with functional diarrhea. The study showed that crofelemer may be a particularly useful option in those patients without a significant pain component to their symptoms, and it may be safe and effective in functional diarrhea, particularly given that its mechanism of action is not constipating. Larger trials are needed to more thoroughly assess safety and longer-term efficacy of crofelemer in functional diarrhea. Judy Nee, MD, was the principal investigator for the study. Dr. Nee is a gastroenterologist at Beth Israel Deaconess Medical Center and an assistant professor at Harvard Medical School. She serves as co-director of the GI Motility Lab at Beth Israel, and specializes in GI motility disorders and functional GI diseases such as IBS, chronic diarrhea, and constipation, as well as movement disorders of the esophagus.
Functional diarrhea, defined as chronic diarrhea for more than 6 months, is a common diagnosis without effective treatments. It is a functional gastrointestinal disorder, meaning it occurs without any other known signs of disease, injury, or structural problem. Patients participating in the study self-reported their daily overall stool consistency based on the Bristol Stool Form Scale (BSFS) and number of loose/watery bowel movements, together with their score for their worst abdominal pain, the score for their abdominal discomfort, and any bloating episodes. The study protocol defined a stool consistency endpoint responder as a patient having ≤ 50% days with BSFS type > 5 (i.e., loose/watery stools), during the prior week compared to the last week of the baseline period.
Investigator-Initiated Study in Chronic Idiopathic Diarrhea
Chronic idiopathic diarrhea is a common complaint of patients presenting to family practitioners and internists, and is one of the most common reasons for referral to gastroenterologists. It is estimated that the prevalence of chronic idiopathic diarrhea in developed countries (including the U.S.) is approximately 3-5%. It has a significant negative effect on health-related quality of life and causes a high economic burden on patients and society.
“Despite significant advances in diagnostics, no organic etiology can be determined in a sizable proportion of patients suffering from chronic idiopathic diarrhea. Variable success for this condition has been observed with non-pharmacologic measures, over-the-counter therapies, and prescription agents. In this pilot study we found that crofelemer improved the symptoms of nearly 60% of patients with idiopathic chronic diarrhea. These results should prompt a larger evaluation of the effects of crofelemer in patients with chronic idiopathic diarrhea,” said Brooks D. Cash, MD, AGAF, FACG, FASGE, the principal investigator for the study. Dr. Cash serves as Chief of the Gastroenterology, Hepatology, and Nutrition Division, and is a Professor of Medicine at the University of Texas Health Science Center at Houston.
The study prospectively recruited patients with chronic idiopathic diarrhea defined as 3 non-bloody loose/watery stools per day or more than 20 non-bloody loose/watery stools per week for ≥ 4 weeks, which corresponds to a stool consistency BSFS score of 6/7 for > 50% of their daily or weekly stools. Primary response was defined as a 50% decrease in mean BSFS 6/7 stool count per week by the end of week 4, and secondary response was defined as a decrease in average stool consistency by more than 2 levels in the BSFS from baseline to the end of treatment. Using this binary outcome, 58.8% of patients improved with crofelemer within the 4-week crofelemer treatment period.
“According to the American College of Gastroenterology, scientific tests show that about 10% to 15% of people in the United States have IBS, and almost twice as many women have IBS than men.1 We look forward to continuing to investigate crofelemer for the treatment and management of chronic refractory diarrhea in patients with IBS-D,” said Conte.
