Outcome Measures

Primary Outcome Measures :

1. Progression-free survival (PFS) rate at 12 months according to RECIST v1.1 [ Time Frame: 12 months from randomisation ]
   The primary objective of this study is to explore the clinical efficacy of atezolizumab and bevacizumab combined with chemotherapy in patients with EGFR-mutant advanced NSCLC after failure of standard EGFR TKIs.

Secondary Outcome Measures :

1. Adverse events according to CTCAE v5.0 [ Time Frame: from the date of randomisation until 90 days after the last dose of protocol treatment ]
   To assess the safety and tolerability of the treatment.
2. Overall survival [ Time Frame: through study completion, from the date of randomisation until death, including OS rate at 12 months. ]
   OS is defined as the time from the date of randomisation until death from any cause. Censoring will occur at the last follow-up date.
3. Objective response [ Time Frame: From date of randomisation until date of treatment completion (until documented disease progression, death or any other causes), assessed up to 2 years. ]
   Objective response is defined as best overall response (CR or PR) across all assessment time-points according to RECIST v1.1, from randomisation until either the end of protocol treatment or the end of follow-up.
4. Quality of Life Core Questionnaire (EORTC QLQ-C30) [ Time Frame: from baseline up to 12 months or until disease progression, whatever is first. ]
   Quality of life will be assessed by the European Organization for Research and Treatment of Cancer Quality of Life Core Questionnaire (EORTC QLQ-C30). The key QoL outcome is the time to deterioration (TTD) in the QLQ-C30 global health status/global QoL.
5. Quality of Life lung cancer-specific module (QLQ-LC13) [ Time Frame: from baseline up to 12 months or until disease progression, whatever is first. ]
   Lung cancer associated symptoms will be measured by the lung cancer-specific module (QLQ-LC13).
6. Extra-cranial PFS [ Time Frame: through study completion, from date of randomisation to documentation of PD outside the CNS, assessed up to 2 years ]
   Extra-cranial progression-free-survival is the time from randomisation to documentation of disease progression outside the central nervous system (CNS) as per RECIST v1.1 or death, whichever occurred first.
7. Intracranial PFS [ Time Frame: through study completion, from date of randomisation to first documented radiographic evidence of CNS progression, assessed up to 2 years. ]
   Intracranial progression-free-survival is defined as the time from randomisation to first documented radiographic evidence of CNS progression. CNS progression is defined as progression due to newly developed CNS lesions and/or progression of pre-existing baseline CNS lesions.
