This is an open-label, non-randomized, phase II multi-centre controlled clinical trial.The total sample size is 51 patients. The population to be included are non-resectable stage IIIA-IIIB non-small cell lung cancer patients.~Patients randomised will receive induction treatment (Atezolizumab 1200mg+ Carboplatin AUC5+Paclitaxel 200 mg/m2 for 3 cycles) and concurrent chemotherapy (CT) -radiotherapy treatment for 3 cycles. At the end of concurrent treatment Atezolizumab 1200mg maintenance treatment will start and will be administered for 12 months (16 cycles).~The primary objective is to assess the efficacy of the treatment (Atezolizumab + Induction chemotherapy (CT) + CT-Radiotherapy) in terms of the Progression Free Survival (PFS) at 12 months according to Response Evaluation Criteria in Solid Tumors (RECIST) Version 1.1.~PFS are defined as the time from inclusion until objective tumor progression or death.~Patient accrual is expected to be completed within 2 years, treatment is planned to extend during 1.5 years and the patients will be followed up for 2 years. The study will end once survival follow-up has concluded.
Open-label, non-randomized, phase II multi-centre controlled clinical trial.~51 non-resectable stage IIIA-IIIB non-small cell lung cancer patients will be enrolled in this trial to evaluate the efficacy of the treatment (Atezolizumab + Induction chemotherapy (CT) + CT-Radiotherapy) in terms of the Progression Free Survival at 12 months
