This phase II trial studies how well stereotactic body radiation therapy works when given together with ipilimumab and nivolumab in treating patients with melanoma that has spread to other parts in the body. Stereotactic body radiation therapy uses special equipment to position a patient and deliver radiation to tumors with high precision. This method can kill tumor cells with fewer doses over a shorter period and cause less damage to normal tissue. Monoclonal antibodies, such as ipilimumab and nivolumab, may interfere with the ability of tumor cells to grow and spread. Giving stereotactic body radiation therapy with ipilimumab and nivolumab may work better in treating patients with melanoma.

PRIMARY OBJECTIVES;
I. To measure improvement in response rate—RR based on Response Evaluation Criteria in Solid Tumors (RECIST) version (v)1.1 when stereotactic ablative body radiation (SABR) is added to ipilimumab + nivolumab compared to historical data.
SECONDARY OBJECTIVES:
I. Measure and compare DCR—disease control rate defined as response plus stable disease based on RECISTv1.1 at 12, 24, 36 weeks versus historical data.
II. To measure tumor CD8+granzyme B+ T cells and FoxP3+ regulatory T cells (T regs) and tumor PD-L1 expression pre-treatment and post-treatment and correlate with response.
III. To determine the toxicity profile compared to historical controls.
OUTLINE:
Patients receive ipilimumab intravenously (IV) over 90 minutes and nivolumab IV over 60 minutes on day 1 of weeks 1, 4, 7, and 10. Patients also undergo 1-3 fractions of stereotactic body radiation therapy on the same day or within 3 days of starting chemotherapy in weeks 1-2, and then receive nivolumab IV over 60 minutes on day 1 in weeks 13, 15, 19, 21, 23, 25, 27, 29, 31, 33, and 35 in the absence of disease progression or unacceptable toxicity.
After completion of study treatment, patients are followed up every 3 months for 1 year, 6 months for 2 years, and then periodically thereafter.
