Inclusion Criteria

• Target Population
• Histologically confirmed malignant melanoma with measurable metastases in the brain. Both asymptomatic and symptomatic patients.
• Cohort A (asymptomatic patients): At least 1 measurable brain metastasis ≥ 0.5 cm in and ≤ 3 cm in longest diameter that has not been previously irradiated. No clinical requirement for local intervention (surgery, radiosurgery, corticosteroid therapy) or other systemic therapy

Cohort B (symptomatic patients): Subjects with neurologic signs and symptoms related to metastatic brain lesions are eligibile. Subjects must have at least 1 measurable brain metastasis ≥ 0.5 cm in and ≤ 3 cm in longest diameter that has not been previously irradiated. No immediate requirement (within 3 weeks prior to first treatment) for local intervention (surgery, radiosurgery, corticosteroid therapy). Steroid use is permitted as defined in the protocol.

• Prior stereotactic radiotherapy (SRT) and prior excision of up to 3 melanoma brain metastases is permitted if there has been complete recovery, with no neurologic sequelae, and measurable lesions remain. Growth or change in a lesion previously irradiated will not be considered measurable. Regrowth in cavity of previously excised lesion will not be considered measurable. lesions or prior excision must have occurred ≥ 3 weeks before the start of dosing for this study
• Must have tumor tissue available for biomarker analysis. Biopsy should be excisional, incisional, punch, or core needle
• Cohort A (asymptomatic): Subjects must be free of neurologic signs and symptoms related to metastatic brain lesions and must not have required or received systemic corticosteroid therapy within 10 days prior to first treatment.

Cohort B (symptomatic): Subjects with neurologic signs and symptoms related to metastatic brain lesions are eligible per Amendment 02. Subjects with neurologic signs and symptoms may be treated with a total daily dose of no more than 4 mg of dexamethasone that is stable or tapering for 10 days prior to first treatment. Subjects with neurologic signs and symptoms who are not being treated with steroids are eligible for Cohort B and should have no experience of seizure within 10 days prior to first treatment.

• Allowable prior therapy:
• Approved adjuvant therapies, which may include molecularly-targeted agents, IFN α, and ipilimumab. Patients who received ipilimumab as adjuvant therapy must have a 6 month washout before receiving any dosing on this study
• For advanced disease, interleukin-2 at any dose and/or IFN-α (any formulation, no washout required); MEK and BRAF inhibitors: washout for at least 4 weeks prior to the start of dosing in this study
• Steroids for physiological replacement are allowed.
• Cohort A (asymptomatic): ECOG performance status ≤1 Cohort B (symptomatic): ECOG performance status ≤2

Exclusion Criteria

• Target Disease Exceptions
• History of known leptomeningeal involvement (lumbar puncture not required)
• Previous stereotactic or highly conformal radiotherapy within 3 weeks before the start of dosing for this study. Note the stereotactic radiotherapy field must not have included the brain index lesion(s)
• Brain lesions >3 lesions which were previously treated with SRT
• Brain lesion size > 3cm 3. Medical History and Concurrent Diseases

a) History of whole brain irradiation b) Subjects with an active, known or suspected autoimmune disease c) Subjects with major medical, neurologic or psychiatric condition who are judged as unable to fully comply with study therapy or assessments should not be enrolled d) Any concurrent malignancy other than non-melanoma skin cancer or carcinoma in situ of the cervix. For any prior invasive malignancy, at least 5 years must have elapsed since curative therapy and patients must have no residual sequelae of prior therapy e) Cohort A (asymptoma
