Trial Outcomes & Findings for The Effect of CSP01 on Chronic Idiopathic Constipation and Irritable Bowel Syndrome With Constipation (NCT NCT03054506)

NCT ID: NCT03054506

Last Updated: 2019-08-20

Results Overview

Colonic Transit Time is the amount of time (in minutes) that the SmartPill capsule spent in the large intestine before expulsion. We measured the difference between CTT pre-treatment and post-treatment and calculated the mean difference for each treatment group. Negative values equal a reduction in CTT.

Measure
CSP01
Subjects in the experimental group will receive CSP01, a non-systemic, orally administered hydrogel capsule, twice a day. CSP01 capsules are taken prior to a meal with water, after which the small particles within the capsules hydrate and expand in the stomach and small intestine. By acting as a bulking agent and possibly reducing colonic transit time through increase of colonic water content, CSP01 may contribute to constipation relief. CSP01: Subjects will take three capsules in the morning before breakfast, and three capsules at night before dinner each day for three weeks.
Carboxymethylcellulose (CMC)
Subjects in the active control group will receive orally administered 3 capsules of carboxymethylcellulose (CMC) capsules twice a day. Carboxymethylcellulose (CMC): Subjects will take three capsules in the morning before breakfast, and three capsules at night before dinner each day for three weeks.
Placebo
Matching placebo consists of an inert mixture supplied by Gelesis Inc. in identical-appearing capsules.Subjects in the placebo group will be administered 3 capsules of placebo twice a day. Placebo: Subjects will take three capsules in the morning before breakfast, and three capsules at night before dinner each day for three weeks.

PRIMARY outcome

Timeframe: Up to 1 week; measured once during the run-in-period and again during third week of the treatment period

Population: All participants who completed the study. (39 participants) Note: One participant who received placebo had pre-treatment CTT data, but post-treatment CTT data was irretrievable due to technical malfunction. This subject's pre-treatment CTT data is included in analysis, but no post-treatment CTT data.

Colonic Transit Time is the amount of time (in minutes) that the SmartPill capsule spent in the large intestine before expulsion. We measured the difference between CTT pre-treatment and post-treatment and calculated the mean difference for each treatment group. Negative values equal a reduction in CTT.

Patient assessment of constipation symptom severity questionnaire. A validated 12-question questionnaire. Numerical scale from 0 to 4 where 0 = absent and 4 = very severe. Possible total score ranges from 0 to 48. Higher total PAC-SYM scores mean a worse outcome. PAC-SYM was completed at four time-points (Day -14, Day 0, Day 15, \& Day 22). Scores were aggregated based on time period as either pre- (Day -14 \& Day 0) or post- (Day 15 \& Day 22) treatment start. Values reported are averages based on patient total scores from these time points. Data was specifically analyzed based on patient diagnosis in addition to treatment.

Patient Assessment of Constipation Quality of Life Questionnaire. A validated questionnaire containing 28 total questions with four sub-sections each broadly ranging from "not at all" to "all of the time" on 0 to 4 scales. Possible total range is 0 to 112. An overall higher total score on the PAC-QOL means a worse outcome. PAC-QOL was completed at four time-points (Day -14, Day 0, Day 15, \& Day 22). Scores were aggregated based on time period as either pre- (Day -14 \& Day 0) or post- (Day 15 \& Day 22) treatment start.

Number of total days that rescue laxatives were used by participants in each treatment group. (The number of days that rescue laxatives were used by each individual patient was calculated and added to the treatment group total)

Outcome measures

Outcome measures
Measure
CSP01
n=19 Participants
Subjects in the experimental group will receive CSP01, a non-systemic, orally administered hydrogel capsule, twice a day. CSP01 capsules are taken prior to a meal with water, after which the small particles within the capsules hydrate and expand in the stomach and small intestine. By acting as a bulking agent and possibly reducing colonic transit time through increase of colonic water content, CSP01 may contribute to constipation relief. CSP01: Subjects will take three capsules in the morning before breakfast, and three capsules at night before dinner each day for three weeks.
Carboxymethylcellulose (CMC)
n=11 Participants
Subjects in the active control group will receive orally administered 3 capsules of carboxymethylcellulose (CMC) capsules twice a day. Carboxymethylcellulose (CMC): Subjects will take three capsules in the morning before breakfast, and three capsules at night before dinner each day for three weeks.
Placebo
n=9 Participants
Matching placebo consists of an inert mixture supplied by Gelesis Inc. in identical-appearing capsules.Subjects in the placebo group will be administered 3 capsules of placebo twice a day. Placebo: Subjects will take three capsules in the morning before breakfast, and three capsules at night before dinner each day for three weeks.

SECONDARY outcome

Timeframe: 55 days (baseline, treatment, & follow-up)

Population: All participants who completed the study and had both pre and post treatment SBM measurements

Average number of Spontaneous Bowel Movements per day. (Spontaneous Bowel Movements include both complete and incomplete bowel movements)
