Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Time to Disease Progression	Time to disease progression was defined as the time from randomization to the earliest occurrence of one or more of the following events: Appearance of =20 polyps (>2 mm in size) at any colonoscopy during the study (Polyps); or; Diagnosis of colorectal malignancy (ColMal).	5 years
Secondary	Time to Treatment Failure	Time to treatment failure was defined as time from randomization to the earliest occurrence of one or more of the following: Appearance of =20 polyps (>2 mm in size) at any colonoscopy during the study (Polyps), or; Diagnosis of colorectal malignancy (ColMal), or; Treatment related dropout (DO). The treatment related dropout was defined as insufficient clinical response, progression of disease, death, adverse event, treatment-related laboratory abnormality, subject no longer willing to participate in study, and other reasons that might be related to treatment as determined by treating physicians in a blind fashion before database release.	5 years
Secondary	Total Number of Colorectal Polyps	Total number of colorectal polyps >2 mm in size, that were detected over Years 1 - 5 cumulatively.; Weighted total number of colorectal polyps over Years 1 - 5 cumulatively was defined as the total number of colorectal polyps >2 mm in size, that were detected over Years 1 - 5, divided by the number of colonoscopies that the participant had during the study.	Years 1 - 5
Secondary	Colorectal Polyp Burden	The polyp burden was defined as the sum of the largest diameters of all polyps (>2 mm in size) over Years 1 - 5 cumulatively.; Weighted colorectal polyp burden over Years 1 - 5 cumulatively was defined as the polyp burden over Years 1 - 5 divided by the number of colonoscopies that the participant had during the study.	Years 1 - 5
