Brief summary: This is an efficacy and safety study of pembrolizumab (MK-3475) combined with pemetrexed/platinum chemotherapy versus pemetrexed/platinum chemotherapy alone in participants with advanced or metastatic nonsquamous non-small cell lung cancer (NSCLC) who have not previously received systemic therapy for advanced disease. Participants will be randomly assigned to receive pembrolizumab combined with pemetrexed/platinum (Investigators choice of cisplatin or carboplatin), OR pemetrexed/platinum (Investigators choice of cisplatin or carboplatin).

With Amendment 10 (effective date 23-Dec-2019), active participants, investigator, and sponsor personnel or delegate(s) involved in the treatment administration or clinical evaluation of the participants will be unblinded, and all participants in the 'control' arm will discontinue saline placebo.

With Amendment 11 (effective date 31-Jan-2022), once the study objectives have been met or the study has ended, participants will be discontinued from this study and will be enrolled in an extension study to continue protocol-defined assessments and treatment.

The primary hypothesis is that pembrolizumab in combination with pemetrexed/platinum chemotherapy prolongs Progression-Free Survival (PFS) and Overall Survival (OS) compared to pemetrexed/platinum chemotherapy alone.


Eligibility criteria: Inclusion Criteria:

* Has a histologically-confirmed or cytologically confirmed diagnosis of stage IV nonsquamous NSCLC.
* Has confirmation that epidermal growth factor receptor (EGFR) or anaplastic lymphoma kinase (ALK)-directed therapy is not indicated.

* If male with a female partner(s) of child-bearing potential, must agree to use adequate contraception starting with the first dose of study medication through 120 days after the last dose of study medication or through 180 days after last dose of chemotherapeutic agents.

Exclusion Criteria:

* Has predominantly squamous cell histology NSCLC.
* Is currently participating and receiving study therapy or has participated in a study of an investigational agent and received study therapy or used an investigational device within 4 weeks prior to administration of pembrolizumab.
* Before the first dose of study medication: a) Has received prior systemic cytotoxic chemotherapy for metastatic disease, b) Has received antineoplastic biological therapy (e.g., erlotinib, crizotinib, cetuximab), c) Had major surgery (\<3 weeks prior to first dose)
* Received radiation therapy to the lung that is \>30 Gray (Gy) within 6 months of the first dose of study medication.
* Completed palliative radiotherapy within 7 days of the first dose of study medication.
* Is expected to require any other form of antineoplastic therapy while on study.
* Received a live-virus vaccination within 30 days of planned start of study medication.
* Has clinically active diverticulitis, intra-abdominal abscess, gastrointestinal obstruction, peritoneal carcinomatosis.
* Known history of prior malignancy except if participant has undergone potentially curative therapy with no evidence of that disease recurrence for 5 years since initiation of that therapy, except for successful definitive resection of basal cell carcinoma of the skin, superficial bladder cancer, squamous cell carcinoma of the skin, in situ cervical cancer, or other in situ cancers.
* Has known active central nervous system (CNS) metastases and/or carcinomatous meningitis.
* Previously had a severe hypersensitivity reaction to treatment with another monoclonal antibody (mAb).
* Known sensitivity to any component of cisplatin, carboplatin or pemetrexed.
* Has active autoimmune disease that has required systemic treatment in past 2 years.
* Is on chronic systemic steroids.
* Is unable to interrupt aspirin or other nonsteroidal anti-inflammatory drugs (NSAIDs), other than an aspirin dose ≤1.3 g per day, for a 5-day period (8-day period for long-acting agents, such as piroxicam).
* Is unable or unwilling to take folic acid or vitamin B12 supplementation.
* Had prior treatment with any other anti-programmed cell death-1 (PD-1), or PD-ligand 1 (PD-L1) or PD-L2 agent or an antibody targeting other immuno-regulatory receptors or mechanisms. Has participated in any other pembrolizumab study and has been treated with pembrolizumab.
* Has an active infection requiring therapy.
* Has known history of Human Immunodeficiency Virus (HIV).
* Has known active Hepatitis B or C.
* Has known psychiatric or substance abuse disorder that would interfere with cooperation with the requirements of the trial.
* Is a regular user (including "recreational use") of any illicit drugs or had a recent history (within the last year) of substance abuse (including alcohol).
* Has symptomatic ascites or pleural effusion.
* Has interstitial lung disease or a history of pneumonitis that required oral of IV glucocorticoids to assist with management.
* Is pregnant or breastfeeding, or expecting to conceive or father children prior to 120 days after the last dose of study medication or through 180 days after last dose of chemotherapeutic agents.
