Nov 9 (Reuters) – Eli Lilly said on Monday its ​oral weight-loss ‌drug Foundayo significantly reduced breathing interruptions during sleep in obese ‌adults ​with moderate-to-severe ⁠obstructive sleep apnea, ⁠meeting the main goal of a late-stage study.

Foundayo reduced ​breathing interruptions by up to ⁠44% on ⁠average at ​52 weeks as measured ​by a diagnostic scale ‌used to measure the severity of sleep apnea, ⁠Lilly said.

Obstructive sleep apnea is a sleep disorder ⁠in ‌which the ⁠upper airway ​repeatedly ‌collapses during sleep, ​lowering oxygen ⁠levels and disrupting breathing.
