A Tissue Collection Study of Pembrolizumab (MK-3475) in Subjects With Resectable Advanced Melanoma

The main purpose of this trial is to evaluate the safety, tolerability and adverse event profile of pembrolizumab in subjects who have high risk melanoma before and after their standard of care surgical resection, and to collect tumor tissue from subjects before and after receipt of pembrolizumab to look at how the experimental drug interacts with tumor tissue. Subjects will receive 1 dose of neoadjuvant pembrolizumab, followed by complete resection and then a year of adjuvant pembrolizumab

9. Female subject's of childbearing potential must have a negative serum pregnancy test within 72 hours prior to receiving the first dose of study medication.
10. The subject must be willing to use protocol defined method(s) of contraception:

Female subjects of childbearing potential must be willing to use 2 methods of contraception, or abstain from heterosexual sexual intercourse for two weeks before the time of the first dose of study medication, while on study, through 120 days after the last dose of study medication.

Female subject's of childbearing potential are defined as those women who have not been surgically sterilized or have not been free from menses for \> 1 year.

Male subjects must agree to use an adequate method of contraception starting with the first dose of study medication, while on study, through 120 days after the last dose of study medication.

Acceptable forms of birth control include condoms, diaphragms, cervical cap, an intra-uterine device (IUD), surgical sterility (tubal ligation or a partner that has undergone a vasectomy), or oral contraceptives, OR the subject must agree to completely abstain from heterosexual intercourse. Abstinence at certain times of the cycle only, such as during the days of ovulation, after ovulation and withdrawal are not acceptable methods of birth control

Exclusion Criteria:

1. Subject has unresectable disease; i.e. in the opinion of the surgical oncologist, all of the subject's melanoma cannot be completely removed with a clear margin.
2. Subject is currently participating in or has participated in a study of an investigational agent or using an investigational device within 4 weeks of the first dose of study treatment.
3. Subject has a known hypersensitivity to pembrolizumab or any of its ingredients.
4. Subject has a diagnosis of immunodeficiency or is receiving systemic steroid therapy or any other form of immunosuppressive therapy within 7 days prior to enrollment.
5. Subject has had a prior monoclonal antibody within 4 weeks prior to study Day 1 or who has not recovered (i.e., ≤ Grade 1 or at baseline) from adverse events due to agents administered more than 4 weeks earlier.

7. Subject has had prior chemotherapy, targeted small molecule therapy, 2 weeks prior to study Day 1 or who has not recovered (i.e., ≤ Grade 1 or at baseline) from adverse events due to a previously administered agent Note: Subjects with ≤ Grade 2 neuropathy are an exception to this criterion
