FDA Fast-Tracks AD109 Sleep Apnea Pill After 44% Trial Reduction
1 articles · Updated · ScienceAlert · May 25
AD109 won FDA fast-track status after a phase 3 trial showed the nightly pill cut patients' apnea-hypopnea index by about 44%, versus an 18% drop with placebo.
646 patients in the US and Canada took AD109 or placebo for 26 weeks after refusing or failing CPAP; by week 26, nearly 42% moved to a lower severity category and almost 18% no longer had obstructive sleep apnea.
Mild side effects included dry mouth, nausea and insomnia, while the drug combines aroxybutynin and atomoxetine to keep upper-airway muscles from collapsing during sleep.
FDA approval is expected in 2027, potentially giving an oral option to a disorder affecting nearly 1 billion people worldwide, many of whom remain untreated or undertreated because CPAP is hard to tolerate.
