Arm 1 Subject Selection:
Eligible patients with stage IV/unresectable stage III melanoma selected to undergo
treatment with an anti-CTLA-4 antibody, an anti-PD-1 antibody, an anti-PD-L1 antibody, or a
combination of an anti-CTLA-4 antibody/anti-PD-1 antibody will be asked to participate in
the study by the Principal Investigator, co-Investigators, or clinical staff.
Inclusion Criteria.
- - Patients with stage III or IV melanoma, with melanoma validated by histology or
cytology.
- - Patients may participate with primary cutaneous melanomas of unknown primary site.
- - ECOG performance status of 0-2.

- - Patients with active disease will be treated with either an anti-CTLA-4 antibody , an
anti-PD-1 antibody, an anti-PD-L1 antibody, or a combination of an anti-CTLA-4
antibody/anti-PD-1 antibody (combined therapy regimens with any other agents are not
allowed on this study).
- - Patient must have a measurable systemic lesion defined as greater than or equal to 10
mm based on PET CT/CT/MRI imaging.
Pretreatment PET CT/CT imaging must be performed ≤
42 days prior to treatment initiation ).
- - Patients with target skin lesions must equal at least 10 mm when their longest
diameters are aggregated.
Target skin lesions (5 maximum) must be at least 5 mm in
their longest diameter to be considered measurable by caliper or ruler.
- - Those patients with a failed biopsy attempt or those with disease that is not amenable
to biopsy will still be eligible for enrollment and will only undergo blood draws
during the study protocol.
- - Both men and women of all races and ethnic groups are eligible for this trial.
- - Ability to understand and the willingness to sign a written informed consent document.
- - Patients with intra-cranial disease or disease involving the central nervous system
are eligible.
Exclusion Criteria.
- - Patients with a history of a systemic autoimmune disease (eg systemic lupus
erythematosus) requiring active therapy.
- - Patients with a history of another malignancy within the last 5 years except for those
patients felt by the treating physician to be cured of that malignancy.
- - Patients with a diagnosis of a mucosal or ocular melanoma.
- - Patients who have undergone adjuvant locoregional radiation therapy if less than 4
weeks prior to day of initial biopsy.
- - Patients who have had prior cytotoxic chemotherapy if less than 6 weeks prior to day
of initial biopsy.
- - Patients who have had prior interferon therapy if less than 4 weeks prior to day of
initial biopsy.
- - Patients who have had prior anti-CTLA-4 antibody or anti-PD-1 antibody or anti-PD-L1
antibody therapy if less than 4 weeks prior to day of initial biopsy.
- - Patients who have had prior IL-2 therapy if less than 4 weeks prior to day of initial
biopsy.
- - Patients who have had prior BRAF inhibitor and/or MEK inhibitor therapy if less than 4
weeks prior to day of initial biopsy.
- - Patients who have received an immunotherapy agent on a previous clinical trial
protocol if less than 4 weeks prior to day of initial biopsy.
- - Patients who are undergoing active steroid therapy if the dose exceeds physiologic
steroid doses (equivalent of prednisone 10 mg po daily or less)
- Patients with ongoing or active infection.
- - Patients with any laboratory test values or serious pre-existing medical condition,
that in the opinion of the investigator, makes the patient unsuitable for the study.
- - Patients unable to comply with the requirements of the study protocol.
Arm 2 Subject Selection:
The following patients will be asked to participate in the study by the Principal
Investigator, co-Investigators, or clinical staff: 1) Patients either undergoing resection
of stage III or stage IV melanoma or have previously undergone resection and who are
considered candidates for adjuvant anti-PD-1 antibody immunotherapy. 2) Patients who
previously underwent resection of stage III or stage IV melanoma and received prior
adjuvant anti-PD-1 antibody immunotherapy and have subsequently developed recurrent
melanoma.
Inclusion Criteria.
- - Patients with a current diagnosis of stage III or IV melanoma or a history of stage
III or IV melanoma, with melanoma validated by histology or cytology.
- - ECOG performance status of 0-2.
- - Patients selected for future adjuvant anti-PD-1 antibody immunotherapy following
resection of stage III or stage IV melanoma or patients who received prior adjuvant
anti-PD-1 antibody immunotherapy for stage III or IV melanoma and have developed
recurrent disease based on physical exam and/or CT/PET CT cross-sectional imaging.
- - Those patients with a failed biopsy attempt or those with disease that is not amenable
to biopsy will still be eligible for enrollment and will only undergo blood draws
during the study protocol.
Of note, any tissue subjected to prior adjuvant radiation
therapy will not be considered for further tissue sampling on this protocol.
- - Both men and women of all races and ethnic groups are eligible for this trial.
- - Ability to understand and the willingness to sign a written informed consent document.

are eligible.
