Trial Summary

What is the purpose of this trial?

This early phase I trial investigates how well radiation therapy, plasma exchange, and pembrolizumab or nivolumab work in treating patients with melanoma. Radiation therapy uses high energy x-rays to kill tumor cells and shrink tumors. Plasma exchange (also known as "plasmapheresis") is a way to "clean" or "flush out" the blood. Immunotherapy with monoclonal antibodies, such as pembrolizumab and nivolumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Plasma exchange may help to improve the effect of standard radiation therapy and immunotherapy treatment on tumor cells of patients with melanoma.

Eligibility Criteria

This trial is for melanoma patients with measurable or non-measurable disease, able to visit the study site for follow-up, and have proper vascular access. Participants must not be pregnant, agree to use contraception if of childbearing potential, provide consent and blood samples for research, have a performance status score of 3 or less (meaning they are capable of self-care), and an sPD-L1 level above 1.7 ng/ml.

Inclusion Criteria

Provide written informed consent

Negative pregnancy test done =< 7 days prior to radiation therapy, for women of childbearing potential only

I can take care of myself but can't do heavy physical work.

Trial OverviewThe trial investigates the combination of radiation therapy (high energy x-rays to kill tumor cells), plasma exchange ('flushing out' the blood), and immunotherapy drugs pembrolizumab or nivolumab in treating melanoma. It aims to see how well these treatments work together in attacking cancer cells and limiting their growth.

Experimental Treatment

Group I: Treatment (radiation therapy, plasma exchange, immunotherapy)Experimental Treatment8 Interventions

Patients undergo radiation therapy daily on days 1-5 (weekdays). Patients then undergo therapeutic plasma exchange over 1-2 hours on the first session starting on the last day of radiation therapy and the last session ending prior to immunotherapy. Beginning day 5, patients receive pembrolizumab IV or nivolumab IV. Treatment with pembrolizumab continues every 3 weeks or treatment with nivolumab continues every 2 weeks in the absence of disease progression or unacceptable toxicity. Patients also undergo blood sample collection throughout the study and SOC CT, PET, and/or MRI scans as clinically indicated during follow-up.

Nivolumab is already approved in United States, European Union, Canada, Switzerland for the following indications:
