Patients may be on or off anti-viral therapy so long as they meet the CD4 count criteria.\n- Step 1 Registration: Clinical/Laboratory Criteria: Women of childbearing potential must have a negative urine or serum pregnancy test within 28 days prior to registration. Women/men of reproductive potential must have agreed to use an effective contraceptive method for the course of the study through 120 days after the last dose of study medication.\n- Step 1 Registration: Disease Related Criteria: Patients are eligible for this trial either at initial presentation of their melanoma or at the time of the first detected nodal, satellite/in-transit, distant metastases, or recurrent disease in prior lymphadenectomy basin or distant site. Nodal, satellite/in-transit metastasis, distant metastases or disease in a prior complete lymphadenectomy basin must have been confirmed histologically by H & E stained slides.\n- Step 1 Registration: Patients who are able to complete questionnaires in English, Spanish or French must participate in the quality of life assessments. (Those patients who cannot complete the quality of life questionnaires can be registered to S1404.\n- Step 2 Registration (Randomization): Women of childbearing potential must plan to have a urine or serum pregnancy test within 72 hours prior to receiving the first dose of study medication.\n- Step 2 Registration (Randomization): Patients who are known to have a change in eligibility status after Step 1 registration are not eligible for Step 2 registration.\n- Step 1 Registration: Disease Related Criteria: Patients with multiple regional nodal basin involvement are eligible. Gross or microscopic extracapsular nodal extension is permitted.\n- Step 1 Registration: Disease Related Criteria: Patients at initial presentation of melanoma must undergo an adequate wide excision of the primary lesion, if present. Patients with previously diagnosed melanoma must have had all current disease resected with pathologically negative margins and must have no evidence of disease at the primary site or must undergo re-resection of the primary site. A full lymphadenectomy is required for all node-positive patients including those with positive sentinel nodes. Patients with recurrent disease who have had a prior complete lymphadenectomy fulfill this requirement as long as all recurrent disease has been resected. For all patients, all disease must have been resected with negative pathological margins and no clinical, radiologic, or pathological evidence of any incompletely resected melanoma. Patients must be registered within 98 days of the last surgery performed to render the patient free of disease.\n- Step 1 Registration: Specimen Submission Criteria: Patients must have available and be willing to submit a minimum of 5 unstained slides from primary, lymph node, or metastatic site to determine PD-L1 expression.\n- Step 1 Registration: Specimen Submission Criteria: Patients must be offered the opportunity to participate in specimen banking.\n- Step 1 Registration: Specimen Submission Criteria: Patients must be willing to have blood draws for PK/ADA ( MK-3475 arm).\n- Step 1 Registration: Prior/Concurrent Therapy Criteria: Patients may have received prior radiation therapy, including after the surgical resection. All AEs associated with prior surgery and radiation therapy must have resolved to ≤ Grade 1 prior to registration.\n- Step 1 Registration: Clinical/Laboratory Criteria: Patients must be ≥ 18 years of age."}

Exclusion criteria

• {"criterion_text":"- Step 1 Registration: Prior/Concurrent Therapy Criteria: Patients must not have received neoadjuvant treatment for their melanoma. Patients must not have had prior immunotherapy including, but not limited to ipilimumab, interferon alfa-2b, high dose IL-2, PEG-IFN, anti-PD-1, anti-PD-L1 intra-tumoral or vaccine therapies. Patients must not be planning to receive any of the prohibited therapies listed in protocol Section 7.2 during the screening or treatment phases of the study.\n- Step 1 Registration: Clinical/Laboratory Criteria: No other prior malignancy is allowed except for the following: adequately treated basal cell or squamous cell skin cancer, in situ cervical cancer, lobular carcinoma of the breast in situ, atypical melanocytic hyperplasia or melanoma in situ, adequately treated Stage I or II cancer (including multiple primary melanomas) from which the patient is currently in complete remission, or any other cancer from which the patient has been disease free for three years.\n- Step 1 Registration: Prior/Concurrent Therapy Criteria: Patients must not be planning to receive concomitant other biologic therapy, radiation therapy, hormonal therapy, other chemotherapy, surgery or other therapy after Step 2 registration.\n- Step 1 Registration: Clinical/Laboratory Criteria: Patients must not have a history of (non-infectious) pneumonitis that required steroids or current pneumonitis.\n- Step 1 Registration: Clinical/Laboratory Criteria: Patients must not have an active infection requiring systemic therapy.\n- Step 1 Registration: Clinical/Laboratory Criteria: Patients must not have active autoimmune disease that has required systemic treatment in 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.\n- Step 1 Registration: Clinical/Laboratory Criteria: Patients must not have received live vaccines within 42 days prior to registration. Examples of live vaccines include, but are not limited to, the following: measles, mumps, rubella, chicken pox, shingles, yellow fever, rabies, BCG, and typhoid (oral) vaccine. Seasonal influenza vaccines for injection are generally killed virus vaccines and are allowed; however, intranasal influenza vaccines (e.g., Flu-Mist®) are live attenuated vaccines, and are not allowed.\n- Step 1 Registration: Clinical/Laboratory Criteria: Patients must not have known active Hepatitis B Virus (HBV) or Hepatitis C Virus (HCV) infection prior to registration.\n- Step 1 Registration: Clinical/Laboratory Criteria: Patients must not have a history or current evidence of any condition, therapy or laboratory abnormality that might confound the trial results, interfere with the patient's participation for the full duration of the trial, or indicate that participation in the trial is not in the patient's best interests, in the opinion of the treating investigator."}
