Summary

This phase 3 trial tests whether maridebart cafraglutide, a drug that may help with weight loss, can reduce sleep apnea episodes in 250 adults who are overweight or obese and not using a breathing machine. Participants receive either the drug or a placebo for 52 weeks. The main goal is to see if the drug lowers the number of breathing pauses during sleep.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance: maridebart cafraglutide (also called AMG 133 or MariTide)
What this could lead to: If it works, this could offer a new drug treatment for sleep apnea that also helps with weight loss, reducing the need for breathing machines.
What could go wrong: This is still a clinical trial, so the drug may not work better than placebo. Side effects are possible, and results may not apply to everyone with sleep apnea.
