Cancer drug trial halted: REC-4881 fails to show promise in Gene-Mutated tumors
NCT ID NCT06005974
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested a daily pill called REC-4881 in 18 adults aged 55+ with advanced solid tumors that had AXIN1 or APC gene mutations. The goal was to see if the drug could shrink tumors or slow cancer growth. The trial was stopped early, so results are limited.
