E.5 End points |
E.5.1 | Primary end point(s) |
•12-weeks progression free survival rate, the probability of being progression-free (loco-regional or distant) or death due to any cause at 12-weeks from trial enrollment. |
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
At 12 weeks
The efficacy evaluations will take place at screening (this will be considered the reference scan), every 2 cycles (every 6 weeks) for the first 4 cycles and subsequently every 3 cycles (every 9 weeks). For patients who stop treatment for reasons other than disease progression, every effort will be made to continue monitoring the disease by radiographic imaging up to 1) initiation of a new anti-tumor therapy, 2) progression of the documented disease, 3) death, or 4) end of the study, whichever occurs first. |
|
E.5.2 | Secondary end point(s) |
•OS, time from enrollment to death from any cause. It will be estimated with Kaplan Meier curves.
•DCR, number percentage of patients achieving DC (RC/RP/SD). It will be calculated as a binary outcome. Exact 95% confidence intervals will be calculated for binary outcomes.
•Incidence of toxicity gratergreater than grade 4, using Common Terminology Criteria for Adverse Events version 4.0 (time frame every two weeks during treatment). Toxicity evaluation will be enumeration of all major toxicity, with proportions calculated for each.
