| Main Objective: • To evaluate the efficacy of RO7247669 and RO7247669 in combination with tiragolumab compared to atezolizumab on the basis of confirmed objective response rate (ORR);Secondary Objective: • To evaluate the efficacy of RO7247669 and RO7247669 in combination with tiragolumab compared to atezolizumab on the basis of PFS, OS, DOR, PFS rate (6 and 12 months), OS rate (6, 12 and 18 months) and DCR • To evaluate the safety of RO7247669 and RO7247669 in combination with tiragolumab compared to atezolizumab • To evaluate the quality of life of participants treated with RO7247669 and RO7247669 in combination with tiragolumab compared to atezolizumab • To characterize the RO7247669 PK profile after administration of RO7247669 and RO7247669 in combination with tiragolumab • To characterize the PK profile of tiragolumab after administration of tiragolumab in combination with RO7247669 • To characterize the PK profile of atezolizumab after administration of atezolizumab • To evaluate the immune response to RO7247669;Primary end point(s): 1. Confirmed ORR, defined as the proportion of participants with a complete response (CR) or partial response (PR) on two consecutive occasions >= 4 weeks apart after randomization, as determined by the investigator according to RECIST v1.1;Timepoint(s) of evaluation of this end point: 1. Up to approximately 30 months for each individual | — |
Secondary
| Measure | Time frame |
|---|---|
| Secondary end point(s): 1. Progression-free survival (PFS) after randomization defined as the time from randomization to the first occurrence of disease progression or death from any cause (whichever occurs first), as determined by the investigator according to RECIST v1.1 2. Overall survival (OS) after randomization, defined as the time from randomization to death from any cause 3. Duration of response (DOR), defined as the time from the first occurrence of a documented objective response to disease progression or death from any cause (whichever occurs first), as determined by the investigator according to RECIST v1.1 4. PFS rate at 6 months and 12 months, defined as the proportion of participants who have not experienced disease progression or death from any cause as determined by the investigator according RECIST v1.1 5. OS rate at 6 months, 12 months, and 18 months, defined as the proportion of participants who have not experienced death from any cause at 6 months, 12 months, and 18 months 6. Disease control rate (DCR), defined as the proportion of participants with confirmed CR or PR as best response, or stable disease maintained for >= 12 weeks, per RECIST v1.1 7. Incidence and severity of adverse events, with severity determined according to national cancer institute common terminology criteria for adverse events, version 5.0 (NCI CTCAE v5) 8. Time to confirmed deterioration (TTCD) from randomization, in patient-reported pain, physical functioning, role functioning, and global health status (GHS)/ quality of life (QoL) scales as assessed through use of the european organisation for research and treatment of cancer (EORTC) item library (IL) 187; confirmed deterioration is defined as a decrease from baseline of >= 10 points (for the physical functioning, role functioning, and GHS/QoL scales) or an increase from baseline of >= 10 points (for the pain scale) that is either maintained for two consecutive assessments or followed by death from any cause within | — |
