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

The primary efficacy endpoint measured the difference in apnea-hypopnea index (AHI) responder rates between active and no stimulation targeted hypoglossal nerve stimulation (THNS) therapy after seven months of follow-up with a predetermined p-value of p<0.025. |

Per trial protocol, a responder is defined to have realized at least a 50% improvement from the baseline AHI, leading to an AHI value below 20. |
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
