Brief Summary

In this study, participants with programmed cell death ligand 1 (PD-L1)-positive non-small cell lung cancer (NSCLC) will be randomized to receive single agent pembrolizumab for up to 35 treatments or standard of care (SOC) platinum-based chemotherapy (carboplatin + paclitaxel or carboplatin + pemetrexed for 4 to 6 21-day cycles). Participants in the platinum-based chemotherapy arms with non-squamous tumor histologies may receive pemetrexed maintenance therapy after the 4 to 6 cycles of chemotherapy. The primary study hypothesis is that pembrolizumab prolongs overall survival (OS) compared to SOC chemotherapy.

Outcome Measures

Primary Outcomes (3)

• Overall Survival (OS) in Participants With a Tumor Proportion Score (TPS) of ≥50%

  OS was determined for participants with a TPS of ≥50% and was defined as the time from randomization to death due to any cause. Participants without documented death at the time of the interim analysis were censored at the date of the last follow-up. The OS was calculated using the product-limit (Kaplan-Meier) method for censored data. The efficacy hypothesis was analyzed using a sequential testing strategy that involved testing a hypothesis only if the superiority of pembrolizumab over chemotherapy was established for all the preceding hypotheses. The order of testing was OS in participants with TPS≥50%, then with TPS≥20%, and finally with TPS≥1%. The OS for participants with a TPS ≥50% is presented.

  Up to approximately 44 months

• Overall Survival (OS) in Participants With a Tumor Proportion Score (TPS) of ≥20%

  OS was determined for participants with a TPS of ≥20% and was defined as the time from randomization to death due to any cause. Participants without documented death at the time of the interim analysis were censored at the date of the last follow-up. The OS was calculated using the product-limit (Kaplan-Meier) method for censored data. The efficacy hypothesis was analyzed using a sequential testing strategy that involved testing a hypothesis only if the superiority of pembrolizumab over chemotherapy was established for all the preceding hypotheses. The order of testing was OS in participants with TPS≥50%, then with TPS≥20%, and finally with TPS≥1%. The OS for participants with a TPS ≥20% is presented.

  Up to approximately 44 months

• Overall Survival (OS) in Participants With a Tumor Proportion Score (TPS) of ≥1%

  OS was determined for participants with a TPS of ≥1% and was defined as the time from randomization to death due to any cause. Participants without documented death at the time of the interim analysis were censored at the date of the last follow-up. The OS was calculated using the product-limit (Kaplan-Meier) method for censored data. The efficacy hypothesis was analyzed using a sequential testing strategy that involved testing a hypothesis only if the superiority of pembrolizumab over chemotherapy was established for all the preceding hypotheses. The order of testing was OS in participants with TPS≥50%, then with TPS≥20%, and finally with TPS≥1%. The OS for participants with a TPS ≥1% is presented.

Biological: pembrolizumab

SOC Treatment

ACTIVE COMPARATOR

Participants receive carboplatin target dose Area Under Curve (AUC) 5 (maximum dose 750 mg) or AUC 6 (maximum dose 900 mg) + paclitaxel 200 mg/m\^2 IV on Day 1 of every 21-day cycle (Q3W) for a maximum of 6 cycles OR carboplatin target dose AUC 5 (maximum dose 750 mg) or AUC 6 (maximum dose 900 mg) + pemetrexed 500 mg/m\^2 IV on Day 1 Q3W for a maximum of 6 cycles; participants with non-squamous histologies may go on to receive optional treatment with pemetrexed 500 mg/m\^2 IV on Day 1 Q3W.
