• •Active infection requiring systemic therapy.
• •Pregnant or breastfeeding
• •Has received a live vaccine within 30 days prior to the first dose of study drug.
• •Examples of live vaccines include, but are not limited to, the following: measles, mumps, rubella, varicella/zoster (chicken pox), yellow fever, rabies, Bacillus Calmette-Guérin (BCG), and typhoid vaccine.

• •Subject is receiving prohibited medications or treatments that cannot be discontinued/replaced by an alternative therapy.
• •Has severe hypersensitivity (≥Grade 3) to pembrolizumab and/or any of its excipients.
• •Has active autoimmune disease that has required systemic treatment in the past 2 years (i.e. with use of disease modifying agents, corticosteroids or immunosuppressive drugs). Replacement therapy (e.g., thyroxine, insulin, or physiologic corticosteroid replacement therapy for adrenal or pituitary insufficiency, etc.) is not considered a form of systemic treatment.
• •Has a history of (non-infectious) pneumonitis that required steroids or has current pneumonitis.
• •Has an active infection requiring systemic therapy.
• •Has a known history of Human Immunodeficiency Virus (HIV). Note: No HIV testing is required unless mandated by local health authority.
• •Has a known history of Hepatitis B (defined as Hepatitis B surface antigen; HBsAg reactive) or known active Hepatitis C virus (defined as HCV RNA \[qualitative\] is detected) infection. Note: no testing for Hepatitis B and Hepatitis C is required unless mandated by local health authority.
• •Has a known history of active TB (Bacillus Tuberculosis).
• •Has a history or current evidence of any condition, therapy, or laboratory abnormality that might confound the results of the study, interfere with the subject's participation for the full duration of the study, or is not in the best interest of the subject to participate, in the opinion of the treating investigator.
• •Has known psychiatric or substance abuse disorders that would interfere with cooperation with the requirements of the trial.
