Multicenter Randomized Parallel Group Phase III Study Comparing the Bowel Cleansing Efficacy, Safety and Tolerability of NER1006 Versus MOVIPREP® Using 2-Day Split-Dosing and 1-Day Morning Split-Dosing Regimen in Adults.

A Multicenter Randomized Parallel Group Phase III Study Comparing the Bowel Cleansing Efficacy, Safety and Tolerability of NER1006 (a Low Volume Bowel Cleansing Solution) Versus MOVIPREP Using 2-Day Split-Dosing and 1-Day Morning Split-Dosing Regimen in Adults.

This study evaluates the efficacy, safety and tolerability of NER1006 versus MOVIPREP in adult patients requiring bowel cleansing prior to any procedure that requires a clean bowel, using a 2-Day evening/morning Split-Dosing and 1-Day morning only Split-Dosing regimens. Approximately 810 patients will be randomised with the aim of achieving a minimum of 245 patients in each of the 3 groups.

• Willing and able to complete the entire study and to comply with instructions.

Exclusion Criteria:

• Patients with active intestinal bleeding episodes or with a clinically significant low hemoglobin level <9 g/dL for women and <11 g/dL for men at screening.
• Known glucose-6-phosphate dehydrogenase (G6PD) deficiency.
• Known phenylketonuria.
• Known hypersensitivity to polyethylene glycols, ascorbic acid and sulfates (not including sulfa-based products) or any other component of the study drug or comparator
