Promising melanoma combo trial halted early – only one patient enrolled
NCT ID NCT06984328
First seen Jun 27, 2026 · Last updated Jul 09, 2026 · Updated 2 times
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.
