General information about the trial
|
|||
Main objective of the trial |
To evaluate the overall bowel cleansing efficacy and the ‘Excellent plus Good’ cleansing rate in the colon ascendens of 2-day split-dosing and 1-day morning of colonoscopy split-dosing regimens with NER1006 compared to a 2-day split-dosing regimen with MOVIPREP®, graded according to the Harefield Cleansing Scale (HCS) in patients undergoing screening, surveillance or diagnostic colonoscopy.
|

Protection of trial subjects |
Screening/Randomisation visit and on the day of colonoscopy prior to the procedure:
- Medical history at the time of screening visit.
- Informed consent.
- Full physical examination, including height and body weight.
- Inclusion/exclusion.
- Orthostatic blood pressure, pulse rate and body temperature measurements.
- 12-lead ECG.
- Blood sample collection: hematology, coagulation profile and biochemistry analyses.
- Urinalysis.
- Pregnancy test (urine) for all female patients of child bearing potential.
- Concomitant medication documentation/review.
- Eligibility check.
After the colonoscopy procedure and recovery period:
- Arterial blood pressure and pulse rate measurements 1 to 2 hours (± 30 minutes) after colonoscopy.
- Physical examination, including body weight.
- Concomitant medication documentation to include medication or IV fluids during colonoscopy.
- Recording and review of adverse events.
Each patient discharged from the colonoscopy unit with an appointment for a follow-up visit. There are two follow up visits. The following assessments performed at each of those two follow up visits:
- Physical examination.
- Blood sample collection: Biochemistry and hematology analyses.
- Review of any outstanding adverse events.

The success rate was the number of patients with successful overall bowel cleansing as a proportion of the number of patients in each group. Missing data were imputed as failures. The treatment effect was the NER1006 success rate minus the MOVIPREP success rate. A Hochberg procedure was used to control Type I error. A closed testing procedure was used to evaluate superiority. Heirarchically, NER1006 2-Day was tested first against MOVIPREP and NER1006 1-Day tested second.

Protocol amendment to update the study location to include the United States, ensuring all the applicable conditions to allow this are included in the protocol. The amendment is also to document a planned increase in the number of patients to be evaluated to account for a 15% drop out as opposed to 10% stated in protocol. These changes are substantial.
