NCT ID NCT07408193
First seen Jun 27, 2026 · Last updated Jul 08, 2026 · Updated 2 times
Summary
This early-phase trial tests whether combining lidocaine and ketamine can reduce severe cancer-related pain that doesn't respond to opioids. Twenty-four adults will receive two weekly infusions of the drug combination or an active placebo in a blinded, crossover design. The goal is to see if this approach provides better pain relief than placebo.
