Trial Outcomes & Findings for Study to Evaluate the Efficacy, Safety, and Tolerability of BOS-589 in the Treatment of Patients With Diarrhea-predominant Irritable Bowel Syndrome (IBS-D) (NCT NCT03977155)

NCT ID: NCT03977155

Last Updated: 2021-06-07

Results Overview

To evaluate in participants with diarrhea-predominant irritable bowel syndrome (IBS-D) the abdominal pain response to BOS-589 after 4 weeks of treatment, relative to placebo. Throughout the 4 weeks of the double blind treatment phase, participants were asked to rate their WAP in the past 24 hours. The participant-reported WAP in the past 24 hours was recorded on a 0 to 10 scale, where 0 corresponded to no pain and 10 corresponded to worst imaginable pain. Higher scores indicated worse outcome.

Population: The ITT Analysis Set included all randomized participants. Here, overall number of participants analyzed signifies only the participants with available data that were analyzed for the outcome measure.

To evaluate the treatment effect of BOS-589 on defecation after 4 weeks, relative to placebo. Participants were asked to record daily stool consistency according to the BSFS most representative of the past 24 hours. The participant-reported BSFS consistency score was based on a 1 to 7 scale where 1 corresponded to a hard stool and 7 corresponded to watery diarrhea. Higher scores indicated worse outcome.

To evaluate the treatment effect of BOS-589 on defecation after 4 weeks, relative to placebo. Participants were asked to record daily stool consistency according to the BSFS worst stool consistency (defined as the loosest stool with the highest BSFS score) in the past 24 hours. The participant-reported BSFS consistency score was based on a 1 to 7 scale where 1 corresponded to a hard stool and 7 corresponded to watery diarrhea. Higher scores indicated worse outcome.

To evaluate the treatment effect of BOS-589 on IBS-related signs and symptoms. Participants were asked to complete 5 questions regarding the severity of their IBS. Each of the 5 questions generated a maximum score of 100, leading to a total possible IBS-SS of 500. The IBS-SS scale ranges from 0 to 500. A higher score indicated greater severity.
