While these two drugs are appropriate for skin melanoma, we are dealing with uveal melanoma, a clinically differently behaving disease, one that does not respond as well as melanoma to drug therapy and is not generally responsive to immunotherapy. Namikawa recently showed 1 response in 20 patients.A retrospective series of 8 patients showed two of the patients had a partial response, while four others had stable disease. Two other patients experienced disease progression. There is as of now insufficient literature support for ipilimumab and nivolumab for metastatic uveal melanoma.
