Study Details
Study Description
Brief Summary
phase II controlled randomized study comparing atezolizumab as single agent to the combination of atezolizumab and bevacizumab in patients with chemonaive metastatic NSCLC with PD-L1 expression. All NSCLC patients with tumor tissue available for biomarker assessment and candidate for first-line therapy are considered eligible for the study. After evaluation of all inclusion and exclusion criteria and after informed consent signature all eligible patients will be randomized to atezolizumab (Arm A) or to the combination of atezolizumab and bevacizumab (Arm B). Disease assessment will be performed every 6 weeks.

Detailed Description
This is a phase II controlled randomized study comparing atezolizumab as single agent to the combination of atezolizumab and bevacizumab in patients with chemonaive metastatic NSCLC with PD-L1 expression.
A total of maximum of 206 patients will be enrolled in the study. Patients will be treated with atezolizumab (1200 mg) every 3 weeks (6-week cycles) or the combination of atezolizumab (1200 mg) every 3 weeks (6-week cycles) plus bevacizumab (15 mg/kg) every 3 weeks until disease progression, unacceptable toxicity or patient refusal. Disease evaluation, along with various assessments, will be made every 3 weeks and every 6 weeks and follow-up every 3 months. Toxicities will be evaluated throughout the study period. A follow-up of 12 months is planned for each patient from the end of treatment .The study will be performed in approximately 20 centers across Italy.

Outcome Measures
Primary Outcome Measures
- Overall Survival (OS) [18 months]
Overall Survival (OS) rate at 18 months in patients treated with atezolizumab alone versus atezolizumab-bevacizumab combination
Secondary Outcome Measures
- Response rate (complete + partial responses) [Up to 24 months]
Response rate will be evaluated by investigators according to RECIST criteria version 1.1. Partial and complete responses will be confirmed following RECIST criteria 1.1.
- Progression-free survival [Up to 24 months]
Progression free survival (PFS) will be calculated from the date of randomization to the first documented evidence of progressive disease or death due to any cause (whichever occurs first).
- Overall survival according to presence of bone and/ or hepatic metastases [Up to 24 months]
Overall response rate (ORR) is defined as the number of subjects with a best overall response (BOR) of CR or PR divided by the number of randomized subjects for each treatment group.
