The hypothesis was to demonstrate NI of NER1006 to Trisulfate Solution (TS) (10% margin). Success rate was number of patients with successful overall bowel cleansing as proportion of number of patients in each group. Treatment effect was NER1006 success rate - TS success rate. A Hochberg procedure was used to control Type I error since there were 2 alternative primary endpoints. An alpha level of 1.25% 1-sided was used. A closed testing procedure used to evaluate superiority if NI was met.

P-value was adjusted for multiple comparisons (two alternative primary endpoints): To be declared superior, primary endpoint must demonstrate non-inferiority and with 1-sided p-value <0.025; the threshold for statistical significance.

The confidence limits were adjusted for multiple comparisons (two alternative primary endpoints): To be declared non-inferior the primary endpoint must show a difference in success rates of no greater than 10% in favour of Trisulfate Solution using lower 1-sided 97.5% confidence limits. Calculated using exact Clopper-Pearson confidence limits.

If at least one of the alternative primary endpoints was met, then key secondary endpoints for the same colon region as met by the primary endpoint were evaluated hierarchically in a pre-specified order. The difference in ADR was calculated as NER1006 rate - TS rate using 1-sided 97.5% confidence limits. Formal testing was to proceed in the hierarchy if preceding key secondary endpoint met non-inferiority. This procedure ensured overall Type I error control at 2.5% 1-sided.

To be declared superior, the key secondary endpoint must demonstrate non-inferiority and show a significant advantage for NER1006 relative to Trisulfate Solution with 1-sided p-value <0.025, the threshold for statistical significance.

To be declared non-inferior, the key secondary endpoint must show a difference in rates of no greater than 10% in favor of Trisulfate Solution using lower 1-sided 97.5% confidence limits. Calculated using exact Clopper-Pearson confidence limits.

If at least one of the alternative primary endpoints was met, then key secondary endpoints for the same colon region as met by the primary endpoint were evaluated hierarchically in a pre-specified order. The difference in PDR was calculated as NER1006 rate - Trisulfate Solution rate using 1-sided 97.5% confidence limits.

If at least one of the alternative primary endpoints were met, then key secondary endpoints were evaluated hierarchichally in a pre-specified order. Non-inferiority was concluded if the 1-sided 97.5% confidence limit (CL) for difference in proportion of events between 2 groups excluded a 10% or greater difference was in favor of Trisulate Solution. Formal testing was to proceed in the hierarchy if preceding key secondary endpoint had at least met non-inferiority.

Formal hierarchical testing of this key secondary endpoints was not performed due to the results of the non-inferiority analysis.
