A female participant is eligible to participate if she is not pregnant (see protocol Section 10.3), not breastfeeding, and at least one of the following conditions applies: a. Not a woman of childbearing potential (WOCBP) as defined in protocol Appendix 3 OR b. A WOCBP who agrees to follow the contraceptive guidance in protocol Section 10.3 during the treatment period and for at least 120 days after the last dose of pembrolizumab and up to 180 days after the last dose of chemotherapeutic agents 11.

E.4 | Principal exclusion criteria |
1. Has predominantly squamous cell histology NSCLC. Mixed tumors will be categorized by the predominant cell type; if small cell elements are present, the participant is ineligible 2. Has symptomatic ascites or pleural effusion. A participant who is clinically stable following treatment for these conditions (including therapeutic thoraco- or paracentesis) is eligible 3. A WOCBP who has a positive urine pregnancy test within 72 hours prior to randomization (see protocol Section 10.3). If the urine test is positive or cannot be confirmed as negative, a serum pregnancy test will be required 4.

Has a known additional malignancy that is progressing or has required active treatment within the past 5 years 11. Has known active untreated CNS metastases and/or carcinomatous meningitis. Participants with previously treated brain metastases may participate provided they are radiologically stable, ie, without evidence of progression for at least 4 weeks by repeat imaging (note that the repeat imaging should be performed during study screening), clinically stable and without requirement of steroid treatment for at least 14 days prior to first dose of study treatment 12.

Has a history or current evidence of any condition, therapy, or laboratory abnormality that might confound the results of the study, interfere with the participant's participation for the full duration of the study, or is not in the best interest of the participant to participate, in the opinion of the treating investigator 21. Has known psychiatric or substance abuse disorder that would interfere with cooperating with the requirements of the study 22. Is pregnant or breastfeeding or expecting to conceive or father children within the projected duration of the study, starting with the screening visit through 120 days after the last dose of pembrolizumab and up to 180 days after the last dose of chemotherapeutic agents |
