Brief Summary:
This is a trial in adult participants with unresectable, locally advanced, Stage III non-small cell lung cancer (NSCLC) treated with pembrolizumab in combination with platinum doublet chemotherapy and standard thoracic radiotherapy followed by pembrolizumab monotherapy. The primary hypothesis of the trial is that within each platinum doublet chemotherapy cohort, the percentage of participants who develop Grade 3 or higher pneumonitis is ≤10%.

Arm Intervention/treatment
Experimental: Cohort A
Participants will receive 1 cycle of pembrolizumab 200 mg on Day 1 with paclitaxel 200 mg/m^2, and carboplatin area under the curve (AUC) AUC6. Approximately 3 weeks later, participants will receive 2 cycles of pembrolizumab 200 mg administered every 3 weeks (Q3W) and carboplatin AUC2 with paclitaxel 45 mg/m^2 administered weekly for 6 weeks in conjunction with standard thoracic radiotherapy (60 Gray [Gy]). To conclude the study treatments, participants will receive 14 additional cycles of pembrolizumab 200 mg administered Q3W.

Other Name: MK-3475

Drug: Paclitaxel 45 mg/m^2
Paclitaxel 45 mg/m^2 IV infusion on Days 1, 8, 15 of each 3-week cycle for Cycles 2, and 3 during radiation therapy.

Drug: Carboplatin AUC6
Carboplatin AUC6 IV infusion on Day 1 of the 21-day cycle for Cycle 1.

Radiation: Thoracic Radiation Therapy (TRT)
The target total dose of TRT will be 60 Gy in 30 daily fractions of 2 Gy, prescribed to the planning target volume.

Drug: Paclitaxel 200 mg/m^2
Paclitaxel 200 mg/m^2 IV infusion on Day 1 of the 21-day cycle of Cycle 1.

Drug: Carboplatin AUC2

Experimental: Cohort B
Participants will receive 3 cycles of pembrolizumab 200 mg on Day 1 of each 3-week cycle and 3 cycles of pemetrexed 500 mg/m^2 and cisplatin 75 mg/m^2. Treatment will be given in conjunction with standard thoracic radiotherapy (60 Gy) in Cycles 2 and 3. To conclude the study treatments, participants will receive 14 additional cycles of pembrolizumab 200 mg administered Q3W.
Drug: Pembrolizumab 200 mg
Pembrolizumab 200 mg intravenous (IV) infusion on Days 1 of each 3-week cycle for up to 17 cycles
Other Name: MK-3475

Drug: Cisplatin 75 mg/m^2

Drug: Pemetrexed 500 mg/m^2
Pemetrexed 500 mg/m^2 IV infusion on Day 1 of each 21-day cycle for Cycles 1, 2, and 3.

Radiation: Thoracic Radiation Therapy (TRT)
The target total dose of TRT will be 60 Gy in 30 daily fractions of 2 Gy, prescribed to the planning target volume.

Primary Outcome Measures :
  1. Percentage of Participants Who Develop Grade 3 or Higher Pneumonitis [ Time Frame: Up to approximately 1 year ]
    Pneumonitis is an immune-mediated adverse event which is of interest in light of the mechanism of action of pembrolizumab.

  2. Percentage of Participants with a Complete or Partial Response [ Time Frame: Up to approximately 1 year ]

    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.

Secondary Outcome Measures :
  1. Progression Free Survival (PFS) [ Time Frame: Up to approximately 1 year ]
    PFS defined as the time from enrollment to the first documented disease progression of local recurrence or distant metastasis or death due to any cause, whichever occurs first, as assessed by blinded independent central review (BICR) according to Response Evaluation Criteria in Solid Tumors (RECIST 1.1) modified to follow a maximum of 10 target lesions and a maximum of 5 target lesions per organ.

  2. Overall Survival (OS) [ Time Frame: Up to approximately 1 year ]
    OS is defined as the time from enrollment to death due to any cause.

  3. Adverse Events (AEs) [ Time Frame: Up to approximately 1 1/4 years ]
    Percentage of participants who experienced one or more AEs.

  4. Discontinuations due to AEs [ Time Frame: Up to approximately 1 year ]
    Percentage of participants discontinuing study treatment(s) due to an AE.
