Can a new capsule ease bone metastasis pain without opioids?
NCT ID NCT07731685
First seen Jul 28, 2026 · Last updated Jul 29, 2026 · Updated 1 time
Summary
This trial tests an experimental drug called VC004 for people with moderate-to-severe pain caused by cancer that has spread to the bones. About 26 adults will receive either a low or high dose of VC004 or a placebo capsule, and researchers will track changes in daily pain scores over time. The goal is to see whether VC004 is safe and whether it can reduce pain intensity.
