CPAP versus APAP for sleep apnea before weight-loss surgery
Part of Brain & nervous system, Hormones & metabolism, Lungs & breathing clinical trials.
This study compares two types of breathing machines (CPAP and APAP) to see which works better for people with sleep apnea who are having weight-loss surgery. It may help improve sleep and recovery around the time of surgery.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are between 18 and 80 years old and on the waiting list for bariatric (weight-loss) surgery (or have a body mass index of 35 or higher, or 30 with related health problems).
- You have been diagnosed with moderate or severe sleep apnea (an apnea-hypopnea index, or AHI, of 15 or higher) that needs treatment.
- You are willing and able to read and sign an informed consent form.
- You do not have central sleep apnea (a condition where the brain fails to signal breathing properly) or periodic breathing (abnormal breathing rhythm).
- You have not had previous surgery for sleep apnea or tried CPAP (continuous positive airway pressure) before and not been able to tolerate it.

This study looks at how bariatric (weight-loss) surgery may change body fat and body shape in people with severe obstructive sleep apnea who use CPAP. It aims to understand what may improve when sleep apnea is better controlled after surgery.
This trial compares two different CPAP machines to see which one works better for treating sleep apnea. You would continue using CPAP as usual and help researchers learn if a newer machine improves comfort or treatment.
This study tests an investigational medicine given as an injection to help people with obstructive sleep apnea and a high body mass index (BMI). It may reduce breathing pauses during sleep and support weight loss, all while you continue using your CPAP machine.
This study tests a new injectable medicine (NNC0487-0111) to help people lose weight and improve obstructive sleep apnea (a breathing condition during sleep). You must already be using a CPAP machine (positive airway pressure device) for your sleep apnea.
This study tests a new APAP machine (called Elara) that helps keep your airway open while you sleep. It looks at how well the device works for people who are already using APAP therapy.
This study tests whether a new injectable medicine called NNC0487-0111 helps people with excess weight and moderate-to-severe obstructive sleep apnea (a condition where breathing stops repeatedly during sleep) lose weight and improve their sleep apnea—without needing a CPAP machine. The goal is to see if better weight loss can reduce sleep apnea symptoms.
