Phase 2 |
Detailed Description
Arm A consists of approximately 20 patients with advanced NSCLC who received first-line anti-PD-1 therapy, who have subsequent disease progression. Arm B consists of approximately 15 patients per disease type (renal cell carcinoma [RCC] progressing on prior anti-PD-1 therapy, triple negative breast cancer [TNBC] progressing on prior anti-PD-1 therapy, NSCLC progressing on check-point inhibitors plus chemotherapy in the first-line setting; and microsatellite instability-high [MSI-high] solid tumors [as determined by local testing for MSI/mismatch repair (MMR)] progressing on prior anti-PD-1 therapy).

Outcome Measures
Primary Outcome Measures
- Efficacy (overall response rate [ORR]) [Up to 6 months]
Assess the efficacy (overall response rate [ORR]) of combining atezolizumab with standard of care chemotherapy in non-small cell lung cancer (NSCLC) and atezolizumab combined with tiragolumab in patients with advanced solid tumors who have progressed after prior exposure to anti-PD- treatment. Overall Response Rate (ORR) is defined as the proportion of patients with confirmed complete response (CR) or partial response (PR (i.e. 2 CRs or PRs at least 4 weeks apart) according to the immune-modified RECIST criteria.
Secondary Outcome Measures
- The incidence of treatment-emergent adverse events (AEs) as a measure of safety [Up to 6 months]
Determine the safety of atezolizmab combined with SOC chemotherapy, and atezolizumab combined with tiragolumab, in patients with NSCLC and other advanced solid tumors.
- The incidence of serious adverse events (AEs) as a measure of safety [Up to 6 Months]
Determine the safety of atezolizmab in patients with NSCLC and other advanced solid tumors
- Determine the disease control rate (DCR) [Up to 6 months]
Estimate the 6-month disease control rate (DCR) in patients with NSCLC and other advanced solid tumors. Disease Control Rate (DCR) is defined as the proportion of patients with CR, PR, or SD for at least 6 months according to the immune-modified RECIST criteria
- Determine the progression-free survival (PFS) [Up to 6 Months]
Estimate the progression-free survival (PFS) in patients with NSCLC and other advanced solid tumors. Progression Free Survival (PFS), defined as the time from the first day of study drug administration (Day 1) to PD as defined by the immune-modified RECIST criteria, or death on study. Patients who are alive and free from disease progression will be censored at the date of last tumor assessment.
- Determine the overall survival (OS) [Up to 6 Months]
Estimate the overall survival (OS) in patients with NSCLC and other advanced solid tumors. Overall Survival (OS), defined as the time from the first day of study drug administration (Day 1) to death on study. Patients who are alive will be censored at the date of last known date alive
