Refractory Merkel Cell Carcinoma

This phase II trial studies how well talimogene laherparepvec and nivolumab work in treating patients with lymphomas that do not responded to treatment (refractory) or non-melanoma skin cancers that have spread to other places in the body (advanced) or do not responded to treatment. Biological therapies, such as talimogene laherparepvec, use substances made from living organisms that may stimulate or suppress the immune system in different ways and stop tumor cells from growing. Immunotherapy with monoclonal antibodies, such as nivolumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Giving talimogene laherparepvec and nivolumab may work better compared to usual treatments in treating patients with lymphomas or non-melanoma skin cancers.
