Plain-English translation of NCT04427826 on ClinicalTrials.gov ↗ ·
Phase 1/2 — A combined trial that checks safety and dosing while also starting to look at whether the treatment works.
This is an early-stage research study testing morphine to help non-invasive ventilation (a breathing mask machine) work more effectively during a sudden, severe worsening of COPD. Researchers believe morphine might help patients breathe better while using the mask by making them more comfortable and reducing the urge to remove it. The study will give patients one injection of morphine at different dose levels and monitor them closely for 4 hours to see if the medication helps and is safe.
When people have a severe COPD flare-up, doctors use a special breathing mask to help them get oxygen and remove carbon dioxide. However, many patients find the mask uncomfortable and want to take it off, which causes the treatment to fail. Researchers believe this medication might make the mask easier to tolerate, allowing more patients to successfully use this life-saving breathing support.

If you qualify, doctors will first perform basic health checks and blood tests, then start you on a non-invasive breathing mask set to specific oxygen levels. You will then receive one injection of morphine—the exact dose will depend on what previous patients in the study experienced. For the next 4 hours, medical staff will monitor you closely and regularly check your breathing, oxygen levels, alertness, and comfort to watch for any side effects. The study is designed so that each patient's response helps doctors figure out the best dose for the next patient.
