Clinical Trial Summary

This trial is a randomized, double-blind, multinational Phase III study to evaluate the efficacy and safety of preemptive treatment with FTD/TPI compared with administration of placebo as follow-up, which is the standard of care, in patients who underwent curative resection of colorectal cancer and then tested positive for ctDNA.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Disease-free survival 1 (DFS1)	The time from the date of enrollment to any of the following events, whichever occurs first: a relapse, development of a secondary colorectal cancer lesion other than a relapse and death from any cause.	Up to 3 years
Secondary	Rate of Conversion to Negative ctDNA	This rate is defined as the proportion of subjects who became negative for ctDNA at the test immediately after completion of study treatment.	Up to 2 years
Secondary	Disease-free survival 2 (DFS2)	The time from the date of enrollment to any of the following events, whichever occurs first: a relapse, development of a cancer lesion other than a relapse (secondary cancer), and death from any cause. In surviving subjects who have not been judged to have a relapse, the last date of survival with confirmation of no relapse be treated as the end of this period.	Up to 3 years
Secondary	Overall Survival (OS)	The time from the date of enrollment to the date of death from any cause. In surviving subjects, the last date of confirmation of survival will be treated as the end of this period. In subjects lost to follow-up, the last date of confirmation of survival before loss to follow-up will be treated as the end of this period.	Up to 3 years
Secondary	Incidence of Adverse Events	For each of the AEs due to the following study treatment, the frequency of cases with the worst grade in all courses according to CTCAE v5.0 will be calculated using all treated patients as the denominator.	Up to 3 years
Secondary	Treatment Completion Rate	This rate will be calculated for each eligible subject in accordance with the following equation. Treatment completion rate (%) = number of treatment courses completed/6 × 100	Up to 3 years
