Kristalose as Bowel Evacuant Prior to Colonoscopy

Benaroya Research Institute20 enrolled

Overview

To determine whether Kristalose causes a significant increase in hydrogen and/or methane gas levels in patients requiring bowel evacuation, and also to determine the safety, efficacy, and patient preference of Kristalose as a bowel evacuant

This is a single center, open-label, pilot study to determine the safety, efficacy, and patient preference of Kristalose as a bowel evacuant prior to colonoscopy. Prior to colonoscopy, subjects will also undergo evaluation for the production of hydrogen and methane gases in the patient's gut (before and after receiving Kristalose) as assessed by a breath analysis instrument. Safety will be assessed by the occurrence of any treatment emergent adverse events. Efficacy will be determined by the endoscopist's rating of the cleanliness of the colon and the incidence of treatment failure (insufficient evacuation of the bowel).

Outcomes

Primary Outcomes

Hydrogen and Methane Gas Production

To evaluate the primary objective of hydrogen and methane gas production as measured by: • Pre- and post-dose breath analysis for hydrogen and methane gas.

Time frame: 3 months

Secondary Outcomes

Efficacy

To evaluate the secondary objective of efficacy, the following endpoints will be measured: * Physician's determination of the cleanliness of the colon will be evaluated by completion of the Boston bowel prep scale.\[4\] * The number and percentage of patient's who by the physician's determination are considered treatment failures (patients with insufficient evacuation of the bowel=Boston bowel prep score \< 5, and/or any colon segment score of 0).

Time frame: 3 months
