Participant Flow

A total of 305 participants were screened, whereof 106 were randomized into the study, and of whom 101 took at least 1 dose of study drug. The clinical study was conducted in 18 centers across 13 countries: Belgium, Czech Republic, Hong Kong, Hungary, Israel, Italy, Slovakia, South Africa, Spain, Sweden, Ukraine, United Kingdom, and United States.

The randomization was to be stratified by center, age (≥12 years old versus \<12 years old), and familial adenomatous polyposis (FAP) phenotype (negative versus positive). The participants were randomized 1:1 to one of the 2 treatments celecoxib or placebo.

PRIMARY outcome

Timeframe: 5 years

Population: ITT population (N: 106) consisted of all participants who were randomized and assigned to treatment. Primary outcome measure was met by 7 (Polyp:7,ColMal:0) participants in the Celecoxib group and 13 (13,0) in the placebo group. Study was early terminated due to low enrollment and lower than expected endpoint rate. No analysis was performed.

Time to disease progression was defined as the time from randomization to the earliest occurrence of one or more of the following events: 1. Appearance of ≥20 polyps (\>2 mm in size) at any colonoscopy during the study (Polyps); or 2. Diagnosis of colorectal malignancy (ColMal).

SECONDARY outcome

Timeframe: 5 years

Population: ITT population (N: 106) consisted of all participants who were randomized and assigned to treatment. Secondary outcome measure was met by 14 (Polyp:7,ColMal:0,DO:14) participants in the Celecoxib and 14 (13,0,12) in the placebo group. Study was early terminated due to low enrollment and lower than expected endpoint rate. No analysis was performed.

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.

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.

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.
