Primary Outcome Measures :
  1. Event-free Survival (EFS) [ Time Frame: Up to approximately 58 months ]

    EFS is defined as the time from randomization to the first occurrence of any of the following events:

    • Local, regional, or distant recurrence of disease as assessed by:

      • Radiographic recurrence by blinded independent central review (BICR)
      • Positive pathology by local assessment
      • Physical examination by local assessment confirmed by positive pathology and/or radiographic recurrence by BICR OR
    • Death due to any cause. EFS will be presented.

  2. Overall Survival (OS) [ Time Frame: Up to approximately 68 months ]
    OS is defined as the time from date of randomization to date of death from any cause. OS will be presented.


Secondary Outcome Measures :
  1. Time to Death or Distant Metastases (TDDM) [ Time Frame: Up to approximately 68 months ]
    TTDM is defined as the time from randomization to the first documented distant metastases or death from any cause, whichever occurs first. The TDDM will be presented.

  2. Number of Participants Who Experience an Adverse Event (AE) [ Time Frame: Up to approximately 16 months ]
    An AE is any untoward medical occurrence in a participant, temporally associated with the use of study treatment, whether or not considered related to the study treatment. The number of participants who experience an AE will be presented.

  3. Number of Participants Who Discontinue Study Treatment Due to an Adverse Event (AE) [ Time Frame: Up to approximately 1 year ]
    An AE is any untoward medical occurrence in a participant, temporally associated with the use of study treatment, whether or not considered related to the study treatment. The number of participants who discontinue study treatment due to an AE will be presented.

  4. Change from Baseline in European Organization for Research and Treatment of Cancer Quality of Life Questionnaire-Core 30 (EORTC QLQ-C30) Global Health Status/Quality of Life (Items 29 and 30) Score [ Time Frame: Baseline and up to approximately 52 weeks ]
    The EORTC QLQ-C30 is a questionnaire to assess the overall quality of life of cancer patients. Participant responses to the questions "How would you rate your overall health during the past week?" and "How would you rate your overall quality of life during the past week?" are scored on a 7-point scale (1=Very Poor to 7=Excellent). Using linear transformation, raw scores are standardized, so that scores range from 0 to 100. A higher score indicates a better overall outcome. The change from baseline in Global Health Status/Quality of Life (EORTC QLQ-C30 Items 29 and 30) combined score will be presented.

  5. Change from Baseline in European Organization for Research and Treatment of Cancer Quality of Life Questionnaire-Lung Cancer Module 13 (EORTC QLQ-LC13) Cough (Item 31) Score [ Time Frame: Baseline and up to approximately 52 weeks ]
    The EORTC QLQ-LC13 is a lung cancer-specific supplemental questionnaire used in combination with the EORTC QLQ-C30. Participant responses to the question "How much did you cough?" are scored on a 4-point scale (1=Not at All to 4=Very Much). Using linear transformation, raw scores are standardized, so that scores range from 0 to 100. A lower score indicates a better outcome. The change from baseline in cough (EORTC QLQ LC13 Item 31) score will be presented.

  6. Change from Baseline in European Organization for Research and Treatment of Cancer Quality of Life Questionnaire-Lung Cancer Module 13 (EORTC QLQ-LC13) Chest Pain (Item 10) Score [ Time Frame: Baseline and up to approximately 52 weeks ]
    The EORTC QLQ-LC13 is a lung cancer-specific supplemental questionnaire used in combination with the EORTC QLQ-C30. Participant responses to the question "Have you had pain in your chest?" are scored on a 4-point scale (1=Not at All to 4=Very Much). Using linear transformation, raw scores are standardized, so that scores range from 0 to 100. A lower score indicates a better outcome. The change from baseline in chest pain (EORTC QLQ-LC13 Item 40) score will be presented.

  7. Change from Baseline in European Organization for Research and Treatment of Cancer Quality of Life Questionnaire-Core 30 (EORTC QLQ-C30) Dyspnea (Item 8) Score [ Time Frame: Baseline and up to approximately 52 weeks ]
    The EORTC QLQ-C30 is a questionnaire to assess the overall quality of life of cancer patients. Participant responses to the question "Were you short of breath?" are scored on a 4-point scale (1=Not at All to 4=Very Much). Using linear transformation, raw scores are standardized, so that scores range from 0 to 100. A lower score indicates a better outcome. The change from baseline in dyspnea (EORTC QLQ-C30 Item 8) score will be presented.

  8. Change from Baseline in European Organization for Research and Treatment of Cancer Quality of Life Questionnaire-C30 (EORTC QLQ-C30) Physical Functioning (Items 1-5) Score [ Time Frame: Baseline and up to approximately 52 weeks ]
    The EORTC QLQ-C30 is a questionnaire to assess the overall quality of life of cancer patients. Participant responses to 5 questions about their physical functioning are scored on a 4-point scale (1=Not at All to 4=Very Much). Using linear transformation, raw scores are standardized, so that scores range from 0 to 100. A higher score indicates a better quality of life. The change from baseline in Physical Functioning (EORTC QLQ-C30 Items 1-5) combined score will be presented.

  • Has previously untreated non-small cell lung cancer (NSCLC) diagnosed by histology or cytology and confirmed as Stage I or II (T1 to limited T3, N0, M0) NSCLC (American Joint Committee on Cancer, AJCC) by chest computed tomography (CT) and positron emission tomography (PET) scan. Participants with pericardium invasion, >2 nodules or 2 nodules that cannot be treated in one field (>2 cm apart and/or total planned target volume [PTV] >163 cc) and diaphragm elevation suggestive of phrenic nerve invasion are excluded
  • Cannot undergo thoracic surgery due to existing medical illness(es) as determined by the site's multi-disciplinary tumor board. Medically operable participants who decide to treat with stereotactic body radiotherapy (SBRT) as definitive therapy rather than surgery are also eligible, if patient's unwillingness to undergo surgical resection is clearly documented
  • Has a Eastern Cooperative Oncology Group (ECOG) Performance Status of 0, 1, or 2
  • Is able to receive SBRT and does not have an ultra-centrally located tumor
  • Has adequate organ function within 7 days prior to the start of study treatment
  • A female is eligible to participate if she is not pregnant, not breastfeeding, and at least one of the following conditions applies: a) not a women of childbearing potential (WOCBP) OR b) A WOCBP and uses contraceptive method that is highly effective (with a failure rate of <1% per year), or be abstinent from heterosexual intercourse as their preferred and usual lifestyle (abstinent on a long-term and persistent basis), during the intervention period and for at least 120 days after the last dose of pembrolizumab/placebo and 180 days after the last radiotherapy dose
  • Male participants are eligible to participate if they agree to the following during the intervention period and for at least 90 days after the last dose of radiotherapy: refrain from donating sperm plus either be abstinent from heterosexual intercourse as their preferred and usual lifestyle (abstinent on a long-term and persistent basis) and agree to remain abstinent or must agree to use contraception per study protocol, unless confirmed to be azoospermic
  • Has a radiation therapy plan approved by the central radiation therapy quality assurance vendor

Exclusion Criteria:

  • Has received prior therapy with an anti-programmed cell death-1 (anti-PD-1), anti-programmed cell death-ligand 1 (anti-PD-L1), or anti PD-L2 agent or with an agent directed to another stimulatory or co-inhibitory T-cell receptor (e.g. cytotoxic T-lymphocyte-associated antigen 4 [CTLA-4], tumor necrosis factor receptor superfamily member 4 [OX-40], tumor necrosis factor receptor superfamily member 9 [CD137])
