Additional Relevant Details Early results evaluating five patients with metastatic melanoma for efficacy and 16 patients for safety were reported. In patients naïve to anti-PD-1 treatment objective responses were observed in three out of four (75%) including one complete response (CR) and two partial responses (PR's). One patient with progressive disease while receiving anti-PD-1 therapy was observed to have stable disease (SD). These data were presented in a poster session on Sunday at the European Society of Medical Oncology (ESMO) Annual Congress 2016 in Copenhagen, Denmark.
