Brief Summary

A first study at one centre, with a new oral gut cleansing solution, NRL994, in patients who were going to have a colonoscopy. The study was to find out how well the new "Low Dose Bowel Prep" (LDBP) worked, and whether it was safe to use.

Detailed Description

A pilot monocentric, open phase I study to investigate the efficacy and safety of a new oral gut cleansing solution NRL994 in patients submitted to colonoscopy.

The study was carried out as an open, uncontrolled investigation in a group of 36 in-patients scheduled for colonoscopy. Patients were enrolled one or two days prior to the endoscopic procedure. Gut cleansing started in the evening prior to the intervention when the first dose of LDBP was taken; bowel preparation was continued in the morning of the day of colonoscopy when the second dose was taken. A patient's participation in the study ended after completion of the endoscopic procedure.

A dose of NRL994 was diluted in 1000 mL of water and consisted of 100 g PEG 3350, 7.5 g sodium sulphate, 4.7 g ascorbic acid, 5.9 g sodium ascorbate, 46 mmol sodium chloride, and 12.46 mmol potassium chloride. The product was flavoured with lemon flavour (2.015 g), anhydrous citric acid (1.565 g), and potassium acesulfame (0.35 g).

Each dose of one litre had to be swallowed within one hour, followed by 500 mL of additional clear fluid.

Study Groups

NRL994 low dose bowel prep (LDBP)

Patients given two doses of NRL994, one on the evening before and one on the morning of their scheduled colonoscopy. Degree of gut cleansing was rated by the colonoscopist and an independent reviewer. Volume of fluid aspirated during colonoscopy and weight of stools/volume of urine from start of cleansing to start of colonoscopy were also measured. Number of patients who reached clear effluent evaluated.

Group Type: EXPERIMENTAL

NRL994

Intervention Type: DRUG

In the afternoon/evening before colonoscopy: 1 litre solution plus 0.5 litre clear fluid.

Day of colonoscopy: 1 litre solution plus at least up to 1 litre clear liquid.
