结局指标
主要结局
Investigator-Assessed Event-Free Survival (INV-assessed EFS)
时间窗: Randomization to the first documented disease recurrence, disease progression or death from any cause, whichever occurs first (up to 5 years)
EFS was defined as the time from randomization to the first documented disease recurrence (per unequivocal radiographic evidence of local recurrence, new second primary SCCHN lesion, or development of distant metastasis), or disease progression \[per Response Evaluation Criteria in Solid Tumors Version 1.1 (RECIST v1.1)\] per assessment by investigator, or death from any cause, whichever occurred first. Progressive disease (PD) was defined as at least a 20% increase in the sum of diameters (SOD) of target lesions, taking as reference the smallest SOD on study (including baseline). Participants without disease recurrence, progression or death at the time of analysis were censored at the time of the last tumor assessment. EFS was estimated using the Kaplan-Meier method.
次要结局
- Overall Survival (OS)(Randomization to death from any cause (up to 5 years, 5 months))
- Independent Review Facility (IRF) Assessed EFS(Randomization to the first documented disease recurrence, disease progression or death from any cause, whichever occurs first (up to 5 years))
- Percentage of Participants Event-Free for IRF-assessed EFS at 1, 2, 3, and 4 Years(From randomization to EFS event or date last known to be alive and event-free at 1, 2, 3, and 4 years)
- Percentage of Participants Event-Free for INV-assessed EFS at 1, 2, 3, and 4 Years(From randomization to EFS event or date last known to be alive and event-free at 1, 2, 3, and 4 years)
- Percentage of Participants Event-Free for OS at 2, 3, and 5 Years(From randomization to OS event or date last known to be alive at 2, 3, and 5 Years)
- Change From Baseline in Physical Function (PF) as Assessed by European Organization for Research and Treatment of Cancer Quality of Life Questionnaire- Core 30 (EORTC-QLQ-C30) Score(Baseline, Day 1 of Cycles 2 to 16 (Cycle length = 21 days); study discontinuation visit (up to 1 year); Follow-up approximately every 3 months until disease recurrence or progression (up to approximately 4.5 years))
- Change From Baseline in Health-related Quality of Life (HRQoL) as Assessed by EORTC-QLQ-C30 Score(Baseline, Day 1 of Cycles 2 to 16 (Cycle length = 21 days); study discontinuation visit (up to 1 year); Follow-up approximately every 3 months until disease recurrence or progression (up to approximately 4.5 years))
- Number of Participants With at Least One Adverse Event (AE)(From first dose of study drug until 90 days after the last dose of study drug (up to 1 year, 3 months))
- Serum Concentration of Atezolizumab(Predose and 0.5 hours post dose on Cycle 1 Day 1; Predose on Day 1 of Cycles 2, 4, 8, and 16 (Cycle length=21 days); study discontinuation visit (up to 1 year))
- Number of Participants With Anti-Drug Antibodies (ADA) to Atezolizumab(Predose on Day 1 of Cycles 1, 2, 4, 8 and 16 (Cycle length=21 days))
