PRIMARY OBJECTIVES:~I. To determine the safety and tolerability of the combination of anti-SEMA4D monoclonal antibody VX15/2503 (anti-SEMA4D VX15/2503) with nivolumab, or ipilimumab, in melanoma patients who have progressed on anti-PD1/L1 based checkpoint inhibitors.~II. To determine the recommended phase II dose and schedule of the combination of anti-SEMA4D VX15/2503 with nivolumab, or ipilimumab, in melanoma patients who have progressed on anti-PD1/L1 based checkpoint inhibitors.~SECONDARY OBJECTIVES:~I. Define the adverse event profile for the agent combinations and determine attribution (i.e. drug related adverse events [AEs]); II. To evaluate clinical response of patients treated with maximum tolerated dose (MTD) or maximum administered dose (MAD) of the combination of anti-SEMA4D with nivolumab, or ipilimumab.~III. To evaluate whether adding anti-SEMA4D to PD1 or CTLA-4 blockade can increase T-cell infiltration into tumors and whether change in T-cell infiltration is associated with response.~OUTLINE: This is a dose-escalation study of anti-SEMA4D monoclonal antibody VX15/2503. Patients are randomized to 1 of 2 arms.~ARM A: Patients receive anti-SEMA4D monoclonal antibody VX15/2503 intravenously (IV) over 60 minutes and nivolumab IV over 30 minutes every 28 days for up to 12 months in the absence of disease progression or unacceptable toxicity.~ARM B: Patients receive anti-SEMA4D monoclonal antibody VX15/2503 IV over 60 minutes and ipilimumab IV over 30 minutes every 21 days for courses 1-4, then receive anti-SEMA4D monoclonal antibody VX15/2503 every 28 days for subsequent courses for up to 12 months in the absence of disease progression or unacceptable toxicity.~After completion of study treatment, patients are followed up every 12 weeks for 2 years, every 6 months for 3 years, then annually thereafter.
This randomized pilot phase I trial studies the side effects and best dose of anti-SEMA4D monoclonal antibody VX15/2503 when given together with nivolumab or ipilimumab in treating patients with stage III or IV melanoma. Monoclonal antibodies, such as anti-SEMA4D monoclonal antibody VX15/2503, nivolumab, and ipilimumab, may interfere with the ability of tumor cells to grow and spread.
