E.5 End points |
E.5.1 | Primary end point(s) |
• Treatment feasibility will be assessed using two co-primary endpoints: treatment completion and excessive toxicity. Treatment will be considered as complete if chemotherapy, chemoradiation (both including panitumumab treatment) and surgery have been administered. The relative dose intensity of the CT and CT/RT needs also to be >= 80%. The relative dose intensity will be calculated for each drug and for radiotherapy (ratio of delivered dose intensity to the planned dose intensity) and averaged over all drugs and RT. The mean has to be >=80% to consider that treatment has been completed. The trial makes use of a Bryant and Day design and maybe stopped early in case of excessive toxicity or in case of too low completion rate (see statistical considerations). Excessive toxicity is defined as the occurrence of grade 4 toxicity plus hospitalization or the occurrence of toxic death (grade 5).
