Study Endpoints

Primary Endpoints

ctDNA positive status (TTPos)
Time from randomization to the first TTPos event, a maximum of 3 years

TTPos is defined as time from randomization until ctDNA positive event: TTPos events are first ctDNA positive result after randomization for the immediate adjuvant chemo arm (Arm 1), 2nd ctDNA positive result after randomization for the delayed adjuvant chemo (Arm 2) and recurrence without a positive ctDNA result for both arms.

Disease-Free Survival (DFS)
Time from randomization to disease-free survival event, a maximum of 5 years]

Time from randomization to first disease-free survival event (recurrence, second primary colorectal cancer or death from any cause).

Secondary Endpoints

Baseline post-surgery ctDNA positivity rate
At time of randomization
Overall Survival (OS)
Time from randomization to death, a maximum of 5 years.
Recurrence
