An Open-Label, Phase II Study to Determine the Immunologic Correlates of Pembrolizumab-Mediated Tumor Regression in Subjects With Advanced Melanoma (KEYNOTE-161)

In this study, participants with advanced melanoma will be treated with pembrolizumab
(MK-3475) and their tumors and blood will be analyzed for changes related to pembrolizumab
therapy.


Inclusion Criteria:

- Has a histologically confirmed diagnosis of unresectable stage III or metastatic
melanoma not amenable to local therapy

- Has testing for a BRAF mutation prior to study entry

- Has measurable disease per RECIST 1.1 as assessed by the investigator/radiology

- Has resolution of toxic effect(s) of the most recent prior chemotherapy to Grade 1 or
less (except alopecia). If the participant received major surgery or radiation therapy
of >30 Gray units, they must have recovered from the toxicity and/or complications
from the intervention

- Has an Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1 within
10 days of study start

- Is not pregnant or breastfeeding

- Female participants of child-bearing potential must be willing to use effective
contraception starting with the screening visit through 120 days after the last dose
of study therapy

Exclusion Criteria:

- Has disease that is suitable for local therapy administered with curative intent

- Has a history of interstitial lung disease

- Has a positive pregnancy test within 72 hours before the first dose of study therapy

- Has received prior therapy with an anti-Programmed Cell Death Protein 1 (PD-1),
anti-Programmed Cell Death-Ligand 1 (PD-L1), anti-Programmed Cell Death-Ligand 2
(PD-L2) agent or with an agent directed to another stimulatory or co-inhibitory T-cell
receptor (eg, CTLA-4, OX-40, CD137)

- Has received prior systemic anti-cancer therapy including investigational agents
within 4 weeks prior to study start

- Has received prior radiotherapy within 2 weeks of start of study therapy

- Has received a live vaccine within 30 days prior to the first dose of study therapy

- Has received transfusion of blood products (including platelets or red blood cells) or
administration of colony stimulating factors (including granulocyte colony stimulating
factor [G-CSF], granulocyte macrophage colony stimulating factor [GMCSF] or
recombinant erythropoietin) within 4 weeks prior to study start

- Is currently participating in or has participated in a study of an investigational
agent or has used an investigational device within 4 weeks prior to the first dose of
study therapy

- Has a diagnosis of immunodeficiency or is receiving chronic systemic steroid therapy
or any other form of immunosuppressive therapy within 7 days prior the first dose of
study therapy

- Has a known additional malignancy that is progressing or has required active treatment
within the past 3 years with the exception of basal cell and squamous cell carcinoma
of the skin, transitional cell carcinoma of urothelial cancer, or carcinoma in situ
(eg, breast carcinoma, cervical cancer in situ) that have undergone potentially
curative therapy

- Has known active CNS metastases and/or carcinomatous meningitis

- Has severe hypersensitivity (≥Grade 3) to pembrolizumab and/or any of its excipients

- Has an active autoimmune disease that has required systemic treatment in past 2 years

- 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) infection

- 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

- 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

- Has known psychiatric or substance abuse disorders that would interfere with
cooperating with the requirements of the study

- Is pregnant or breastfeeding or expecting to conceive or father children starting with
the screening visit through 120 days after the last dose of study therapy
