NSCLC, Stage IIIA

To investigate the efficacy and safety of neoadjuvant treatment with Tislelizumab combined with chemotherapy for initially unresectable N2/III non-small cell lung cancer.

Exploratory study evaluating the potential of immune signature profiling for predicting response in patients with resectable Stage II, IIIA and select IIIB (T3N2 only) non-squamous Non-Small Cell Lung Cancer (NSCLC) to neoadjuvant ATEZOLIZUMAB plus Carboplatin/nab Paclitaxel Atezolizumab is given as intravenous infusion at a fixed dose of 1200 mg, day 1 of each 21-day cycle (every 3 weeks) for 3 cycles during the neoadjuvant treatment phase, Carboplatin at an initial dose of AUC (area under curve) 5 mg/mL/min, intravenously day 1 of each 21-day cycle for 3 cycles during the neoadjuvant treatment Phase, and Nab-Paclitaxel (Abraxane) at 100 mg/m2, intravenously day 1, 8 and 15 of each 21-day cycle for 3 cycles during the neoadjuvant treatment phase. Surgery after the 3rd cycle Atezolizumab / Carboplatin / Nab-Paclitaxel is standard procedure.
