| E.5 End points |
| E.5.1 | Primary end point(s) |
PFS, defined as the time from randomization to the time of radiographic
progression (as assessed by irRECIST) or death from any cause during
the study |
|
| E.5.1.1 | Timepoint(s) of evaluation of this end point |
| We expect to reach the data-driven time point for PFS-analysis (95% PFS events in all patients) 2.5-3 years after the study opens. lf this is not met within 18 months after inclusion of the last patient, the PFS analysis will beperformed at this time point. |
|
| E.5.2 | Secondary end point(s) |
The secondary efficacy outcome measures will beassessed in the ITT population and in the PD-L1-positive subpopulation as follows:
- Overall survival (OS), defined as the time from the date of randomization to the date of death from any cause
- Objective tumor response rate (ORR), defined as the proportion of patients with an objective tumor response (either partial response [PR] or complete response [CR] per investigator using irRECIST)
- Durable response rate (DRR), defined as the proportion of patients with an objective tumor response lasting at least 6 months
- Duration of objective response (DOR) among patients with an objective response
- PFS in the PD-L1-positive subpopulation assessed by irRECIST
- PFS, ORR, DRR and DOR assessed by RECIST v1.1
- lnvestigator-assessed PFS using irRECIST, with no censoring at missing scans
- lnvestigator-assessed PFS using RECIST v1.1, with no censoring at missing scans
Safety Outcome Measures
- lncidence, nature, and severity of adverse events graded according to NCI CTCAE v4.0 and AESls for atezolizumab.
- Changes in vital signs, physical findings, and clinical laboratory results
Exploratory Outcome Measures Assessment of immunological response:
- ldentification of biomarkers for clinical response, toxicity and immune response
- Characterization of tumor evolution and changes in immunological milieu induced by the combination therapy (atezolizumab+chemo), as compared to chemo only
- Development in FQ score(11). The analyses will include time to deterioration (TTD) in the FQ score, defined bya minimally clinically important difference (MCID) of ≥ 3 points. The maximum total FQ score is 33 points. For mean score, a separate analysis will beperfomed for subjects with a baseline FQ score ≥ 21 points
- Development in NRS pain intensity score for average pain the last 24 hours (corresponding to one item in BPI). The analyses will include TTD in the pain intensity score, defined by a minimally clinically important difference (MCID) of ≥ 2 points (scale 0-10). For mean score, a separate analysis will beperformed for subjects with a baseline score ≥ 4 points
- Mean changes and TTD in item 15of the EORTC QLQ-C15-PAL, defined bya MCID ≥ 20 points at patient individual level. A change of ≥ 10 points is considered to be of clinical importance at group level. The development of other scales and items of QLQ-C15 will also be recorded |
