A once-nightly oral capsule helped management obstructive sleep apnea in a big, part 3 medical trial introduced on the 2026 ATS Worldwide Convention. The drug, known as AD109, is the primary remedy to deal with OSA by addressing its underlying mechanisms and concentrating on the neuromuscular causes of airway collapse. “Aroxybutynin and Atomoxetine (AD109) for Obstructive Sleep Apnea: A Randomized Part 3 Trial” can be revealed within the American Journal of Respiratory and Important Care Drugs.
The trial, known as SynAIRgy, confirmed that sufferers who took AD109 had fewer respiration interruptions throughout sleep, much less oxygen deprivation, and improved blood oxygen ranges general. Greater than 40 p.c of sufferers noticed their OSA illness severity class enhance, and 18 p.c achieved full illness management.
These outcomes present encouraging proof that concentrating on neuromuscular dysfunction can translate into significant medical outcomes, aligning with our evolving understanding of the illness biology.”

Steady Constructive Airway Strain (CPAP) is the gold normal therapy for OSA, however many sufferers are unable to tolerate therapy. AD109 might assist fill that hole with a better therapy possibility, Dr. Strollo mentioned.
“In lots of different persistent ailments, equivalent to heart problems, bronchial asthma, or sort 2 diabetes, it could be unthinkable for almost all of identified sufferers to stay untreated or undertreated. But that continues to be the truth in OSA,” he mentioned. “An oral capsule that targets the underlying neuromuscular drivers of airway collapse throughout sleep might assist handle this hole and broaden the vary of efficient choices for sufferers who stay untreated at the moment.”
AD109 combines two medicines, aroxybutynin and atomoxetine, which work collectively to assist muscle tissue within the throat and stop the airway from sagging or collapsing throughout sleep.
For the trial, which ran for six months at 69 websites throughout the U.S. and Canada, researchers enrolled 646 adults with delicate to extreme OSA who could not tolerate or refused CPAP.
Sufferers taking AD109 noticed their apnea-hypoxia index, which measures the variety of respiration interruptions per hour, lower by about 44 p.c, in contrast with 18 p.c within the placebo group. Oxygen desaturation index (the variety of instances in the course of the evening that blood oxygen drops) and hypoxic burden (oxygen deficiency) additionally improved within the AD109 group.
Importantly, enhancements had been noticed persistently throughout a broad vary of sufferers, together with these with various severity ranges and physique sorts.
Together with improved outcomes, the drug confirmed an appropriate security profile with delicate, anticipated negative effects. The commonest negative effects had been dry mouth, nausea, insomnia, and issue urinating. Round 21 p.c of sufferers discontinued remedy resulting from negative effects.
Dr. Strollo famous that the outcomes can be revealed alongside a companion mechanistic overview by ATS within the American Journal of Respiratory Cell and Molecular Biology.
“Collectively, these peer-reviewed articles join late-stage medical outcomes with the organic mechanisms that drive the illness, focused by the mechanism of motion of AD109, offering a extra full and built-in view of OSA and strengthening confidence within the strategy,” he mentioned.
AD109 has acquired Quick Observe designation from the FDA for the therapy of OSA, recognizing the numerous unmet want for efficient, well-tolerated pharmacologic therapies for OSA. Apnimed has submitted its New Drug Utility (NDA) for AD109 to the FDA. Primarily based on FDA suggestions, Apnimed expects a possible PDUFA goal motion date in 1Q 2027, topic to FDA acceptance of the NDA for overview.
