• International normalized ratio (INR) OR prothrombin time (PT) =< 1.5 x ULN unless patient is receiving anticoagulant therapy as long as PT or partial thromboplastin time (PTT) is within therapeutic range of intended use of anticoagulants (within 10 days prior to the start of trial treatment)
• Activated partial thromboplastin time (aPTT)/PTT =< 1.5 x ULN unless patient is receiving anticoagulant therapy as long as PT or partial thromboplastin time (PTT) is within therapeutic range of intended use of anticoagulants (within 10 days prior to the start of trial treatment)
• Female patients of childbearing potential must have a negative urine or serum pregnancy test within 72 hours prior to receiving the first dose of trial medication. If the urine test is positive or cannot be confirmed as negative, a serum pregnancy test will be required
• Male and female patients of childbearing potential must be willing to use an adequate method of contraception as outlined, for the course of the trial through 120 days after the last dose of trial drug o Note: Abstinence is acceptable if this is the usual lifestyle and preferred contraception for the patient

Exclusion Criteria:

• Any approved anticancer therapy, including chemotherapy, hormonal therapy, or radiotherapy, within 5 years prior to initiation of study treatment; however, the following are allowed:

  • Hormone-replacement therapy or oral contraceptives

• Malignancies other than the disease under study within 5 years prior to Cycle 1, Day 1, with the exception of those with a negligible risk of metastasis or death and with expected curative outcome or undergoing active surveillance per standard-of-care management (e.g., chronic lymphocytic leukemia Rai Stage 0, prostate cancer with Gleason score ≤ 6, and prostate-specific antigen (PSA) ≤ 10 mg/mL, etc.)
• Patients who are receiving any other investigational agents concurrently.
• History of allergic reactions attributed to compounds of similar chemical or biologic composition to pembrolizumab, cisplatin, carboplatin, pemetrexed or gemcitabin.
• Patients with active hepatitis B or C infections or a history of HIV infection.

• Patients positive for hepatitis C virus (HCV) antibody are eligible only if polymerase chain reaction (PCR) is negative for HCV RNA.
• Uncontrolled intercurrent illness including, but not limited to, ongoing or active infection including tuberculosis (TB), symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, or psychiatric illness/social situations that would limit compliance with study requirements.
• Known clinically significant liver disease, including active viral, alcoholic, or other hepatitis; cirrhosis; fatty liver; and inherited liver disease
• Patients with controlled Type 1 diabetes mellitus on a stable insulin regimen may be eligible.
• Severe infections within 4 weeks prior to Cycle 1, Day 1, including but not limited to hospitalization for complications of infection, bacteremia, or severe pneumonia
