Trial Outcomes & Findings for Polyphenon E in Treating Patients With High-Risk of Colorectal Cancer (NCT NCT01606124)

NCT ID: NCT01606124

Last Updated: 2017-10-27

Results Overview

The primary endpoint is based on a modified intent-to-treat procedure which includes all patients with baseline and 6-month ACF data. The percent change in rectal ACF (≤ 15 cm from the anal verge) for each patient is calculated as their Pre-Registration number of rectal ACF minus the number of rectal ACF present at the 6-month post-intervention exam, divided by the number of rectal ACF present at Pre-Registration times 100.

PRIMARY outcome

Timeframe: 6 months

Population: Patients with baseline and 6-month ACF data were included in this analysis.

The primary endpoint is based on a modified intent-to-treat procedure which includes all patients with baseline and 6-month ACF data. The percent change in rectal ACF (≤ 15 cm from the anal verge) for each patient is calculated as their Pre-Registration number of rectal ACF minus the number of rectal ACF present at the 6-month post-intervention exam, divided by the number of rectal ACF present at Pre-Registration times 100.
