Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Main Objective: The primary objective is to assess the effectiveness of aspirin on the disease-free survival at 3 years after curative surgery for colonic adenocarcinoma with PI3K mutation.;Secondary Objective: -Disease-free survival at 5 years -Overall survival at 5 years -Compliance to aspirin (Thromboxane B2 measurements and comptability of containers) -Severe bleeding grade 3-4 events and hospitalization according to NCI-CTC grading 4.0 -Adverse event reported and graded according to NCI-CTC grading 4.0 ;Primary end point(s): The objective is to demonstrate a reduction of 44% on the disease-free survival(DFS) rate at 3 years. DFS is defined as the time from date of randomization to date of first local or distant recurrence, or second colorectal cancer, or death (from any cause), whichever occurred first. ;Timepoint(s) of evaluation of this end point: 3 years after the inclusion of the last patient | — |
