NCT ID NCT04188418
First seen Jun 27, 2026 · Last updated Aug 12, 2026 · Updated 2 times
Summary
This study tests if fast-acting opioids (fentanyl or morphine) can reduce shortness of breath during or after walking in 150 cancer patients who already take strong painkillers. Participants will take the drug or a placebo before a short walk test, and researchers will measure changes in their breathing difficulty. The goal is to find a new way to improve daily comfort and activity for people with advanced cancer.
