Pilot Study to Assess Tolerability and Feasibility of Oral Sulfate Solution (SUPREP) in Hospitalized Patients

Study Overview
=================
Brief Summary
-----------------
This study will test the efficacy, tolerability, and feasibility of an oral sulfate solution (SUPREP) for inpatient colonoscopy preparation, compared to the standard of care (GoLytely). The hypothesis is that SUPREP will be well tolerated and non-inferior to standard polyethylene glycol bowel preparation for colonoscopies in an inpatient setting. To test this, at least 124 subjects who are undergoing an inpatient colonoscopy will be randomized to receive either SUPREP or standard of care. The Boston Bowel Preparation Score will be collected as standard of care for both groups. Safety will be monitored from standard of care blood tests and ECG (when indicated). Subjects will be given a survey to assess how tolerable they found the procedure. A non-inferiority design will be used to compare SUPREP to the standard of care polyethylene glycol preparation. Data analysis will be performed on Boston Bowel Preparation Score and rate of failure of preparation (measured as number of successful subsequent colonoscopies).

Design Details

Primary Purpose: Diagnostic
Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Double


Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: Oral sulfate solution (SuPREP arm)<br>Per the package insert: The dose for colon cleansing requires administration of two bottles of SUPREP Bowel Prep Kit. Each bottle is administered as 16 oz of diluted SUPREP solution with an additional 1quart of water taken orally. The total volume of liquid required for colon cleansing (using two bottles) is 3 quarts (approximately 2.8 L) taken orally prior to the colonoscopy outlined below under frequency. Two 6 oz bottles of oral solution: Each 6 oz bottle contains: sodium sulfate 17.5 g, potassium sulfate 3.13 g, magnesium sulfate 1.6 g. | Drug: SUPREP Bowel Prep Kit<br>* Bowel prep prior to colonoscopy<br>|
| Active Comparator: Polyethelene Glycol (GoLytely arm)<br>Polyethylene Glycol Bowel Prep Kit | Drug: Golytely Oral Product<br>* Bowel prep prior to colonoscopy<br>|
