E.5 End points |
E.5.1 | Primary end point(s) |
The primary endpoint of the study is response rate. |
Taux de réponse (Réponse Complète + Réponse Partielle) en utilisant RECIST v1.1 |
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
Treatment evaluation visit |
|
E.5.2 | Secondary end point(s) |
Secondary efficacy endpoints are: - PFS is defined as the time from the date of starting treatment to the date of progression or death (from any cause). Patients alive without documented objective PD at the time of the final analysis will be censored at the date of their last objective tumor assessment. - OS is defined as the time from the date of starting treatment to the date of patient death (from any cause) or to the last date the patient was known to be alive. Patients still alive at the time of the analysis will be censored using the date of last news. - Disease control rate (DCR) is defined as the percentage of patients achieving CR, PR, or stable disease (SD).
Secondary safety endpoints are: - Toxicity will be evaluated according to the U.S. National Cancer Institute's Common Terminology Criteria for Adverse Events (NCI-CTCAE) version 5.0.
