Experimental: Pembrolizumab Standard of Care
Participants will receive standard of care pembrolizumab combined with platinum-doublet chemotherapy for 4 cycles, then pembrolizumab plus pemetrexed maintenance for up to 31 additional cycles. The platinum doublet would be pemetrexed plus the investigator's choice of either cisplatin or carboplatin.
Pembrolizumab, 200 mg, Day 1 of each 21-day cycle (Q3W), intravenous infusion (IV), standard of care in most countries
Pemetrexed, 500 mg/m^2 infusion, standard of care, Q3W, IV
Carboplatin AUC 5 mg/mL/min, IV infusion, Day 1 of each 21-day cycle for 4 cycles (Cycles 1 - 4). Investigator's choice of either cisplatin or carboplatin.
Cisplatin, 75 mg/m^2, IV infusion, Day 1 of each 21-day cycle for 4 cycles (Cycles 1 - 4). Investigator's choice of either cisplatin or carboplatin.
- Objective Response (OR) [ Time Frame: Up to approximately 25 months ]Objective response rate is the proportion of participants who have a confirmed complete response (CR) or partial response (PR). Objective response rate is assessed by blinded independent central review (BICR) according to Response Evaluation Criteria in Solid Tumors (RECIST) 1.1. Complete Response (CR): Disappearance of all target lesions. Any pathological lymph nodes (whether target or non-target) must have reduction in short axis to <10 mm. Partial Response (PR): At least a 30% decrease in the sum of diameters of target lesions, taking as reference the baseline sum diameters.
- Tumor Mutation Burden (TMB) [ Time Frame: Baseline ]Circulating cell-free DNA (cfDNA) allows the exploration of the mechanisms of progression on and resistance to pembrolizumab and chemotherapy, and assesses the role of the metagenomics (microbiome) and metabolomics in response to pembrolizumab + chemotherapy in NSCLC. The tumor mutation burden in circulating cfDNA will be estimated in blood.
- Progression Free Survival (PFS) [ Time Frame: Up to approximately 25 months ]PFS is defined as the time from enrollment to the first documented disease progression or death due to any cause, whichever occurs first assessed by blinded independent central review (BICR) according to Response Evaluation Criteria in Solid Tumors (RECIST 1.1).
- Overall Survival (OS) [ Time Frame: Up to approximately 25 months ]OS is defined as the time from the start of treatment to death due to any cause.
- Adverse Events (AEs) [ Time Frame: Up to 30 days after last dose of study treatment (Up to approximately 26 months) ]Percentage of participants who experienced one or more AEs.
- Discontinuations from Study Drug Due to an Adverse Event [ Time Frame: Up to approximately 25 months ]Percentage of participants discontinuing study treatment(s) due to an AE.
