Summary

This study tested a new drug called acasunlimab, given alone or with pembrolizumab, in people with advanced melanoma that had stopped responding to standard treatments. The trial was terminated early after enrolling only one participant, so no conclusions can be drawn about safety or effectiveness. The goal was to see if the combination could shrink tumors and improve survival.
