LivaNova Announces OSPREY Clinical Study Meets Primary Safety and Efficacy Endpoints

Top-line results compared to baseline at six months:

Median apnea-hypopnea index reduction of 66.2%

Median oxygen desaturation index reduction of 63.3%

LivaNova PLC (NASDAQ:LIVN), a market-leading medical technology company, today announced that it met the primary endpoints for its OSPREY randomized controlled trial (RCT), Treating Obstructive Sleep Apnea Using Targeted Hypoglossal Nerve Stimulation. Together with its safety endpoints, the RCT achieved statistical significance of its primary endpoint responder rates^1,2 between the treatment arm and the sham arm for the LivaNova aura6000™ System. The aura6000 is an implantable hypoglossal neurostimulator intended to treat adult patients with moderate to severe obstructive sleep apnea (OSA).

In the OSPREY study, apnea-hypopnea index (AHI) and oxygen desaturation index (ODI) reductions are analyzed as part of the study's secondary endpoints. Comparing median values from baseline to six months with therapy (assessed at the seven-month follow-up visit), OSPREY subjects in the device stimulation group experienced significant reductions in these endpoints as follows:

• AHI reduced by 66.2% when the median at baseline of 34.3 is compared to the median of 11.6 at six months.
• ODI reduced by 63.3% when the median at baseline of 34.9 is compared to the median of 12.8 at six months.

Once the six-month results analysis is completed, LivaNova will submit the OSPREY clinical data to the U.S. Food and Drug Administration (FDA) as part of its premarket approval submission for the aura6000 System.

"The study results reinforce our belief that targeted hypoglossal nerve stimulation provides a compelling alternative for patients with obstructive sleep apnea. The significant reductions in AHI and ODI achieved after only six months of therapy gives us strong evidence of this technology's potential at 12 months and beyond," said Vladimir Makatsaria, Chief Executive Officer of LivaNova. "I would like to thank the patients and physicians who have participated in OSPREY to date. We look forward to evaluating the full results as patients complete 12 months of therapy."

Beyond the primary endpoints, the OSPREY trial will continue to collect long-term data. After all subjects have completed 12 months with therapy (assessed at the 13-month follow-up visit), LivaNova expects the data to be available in the first half of 2025.

"In addition to meeting the primary safety and efficacy outcomes, the reductions in AHI and ODI after only six months of therapy demonstrate a significant clinical impact for the patients," said Dr. Atul Malhotra, lead investigator for the study, who is also a professor of medicine at University of California San Diego School of Medicine and sleep medicine specialist at University of California San Diego Health.

There were no serious adverse device-related or procedure-related events reported in OSPREY throughout the primary endpoint visits.

About OSPREY

OSPREY is a prospective, multi-center, randomized controlled open-label trial demonstrating the safety and efficacy of the aura6000™ Hypoglossal Nerve Stimulator System versus a no stimulation control in subjects with moderate to severe OSA who have failed or are unwilling to use positive airway pressure treatment. CAUTION—the aura6000 System is an investigational device. Limited by Federal (or United States) law to investigational use.
