Brief Summary:
This is a multicenter, open label, Phase 2 study, with 3 parallel cohorts. The aim of the study is to evaluate the efficacy of APX005M administered at 2 different schedules to adult subjects with unresectable or metastatic melanoma. Subjects who have not received prior immunotherapy will be alternately assigned to 1 of 2 cohorts (2 different APX005M administration schedules) as long as both are open. Subjects who have failed approved immunotherapy regimens will be assigned to a 3rd cohort of APX005M in combination with radiation therapy.
