Inspire Medical Systems, Inc. Announces Presence at SLEEP 2026 and Publication of PREDICTOR Study

Highlights New Clinical Data, Technology Advancements, and Cardiovascular Outcomes Research

MINNEAPOLIS, June 16, 2026 (GLOBE NEWSWIRE) -- Inspire Medical Systems, Inc. (NYSE: INSP), a medical technology company focused on innovative, minimally invasive solutions for patients with obstructive sleep apnea (OSA), today announced its participation in SLEEP 2026, the 40th annual meeting of the Associated Professional Sleep Societies (APSS), taking place June 14–17 in Baltimore, Maryland.

SLEEP is the premier global forum for sleep medicine and research, jointly hosted by the American Academy of Sleep Medicine (AASM) and the Sleep Research Society (SRS).

Advancing Innovation and Clinical Evidence

“We are pleased to return to SLEEP and showcase the continued evolution of the Inspire platform, including the Inspire V system, alongside compelling new clinical data demonstrating real-world effectiveness,” said Tim Herbert, Chairman and Chief Executive Officer. “Our long-standing partnership with SLEEP reflects our commitment to advancing physician education and improving outcomes for patients with OSA worldwide.”

At Booth #525, attendees can explore:

• The Inspire V system and recent technology advancements
• Clinical evidence supporting closed-loop therapy detailing respiratory sensing and inspiratory overlap
• The Inspire SleepSync™ remote patient management platform
• Resources for establishing and scaling Inspire programs
  
  

New Clinical Insights: Hypoxic Burden and Cardiovascular Outcomes

Multiple presentations at SLEEP 2026 will highlight the growing body of evidence supporting Inspire therapy, particularly in improving cardiovascular risk markers. Separately, Inspire will highlight additional research at its exhibit booth, including recent peer-reviewed articles on hypoxic burden and cardiovascular outcomes, which complement these presentations and are not being presented as part of the SLEEP 2026 program.

The first article from Dr. Xu¹ is a secondary analysis from the STAR trial that demonstrated:

• Significant reductions in hypoxic burden, a key physiologic measure of oxygen desaturation linked to OSA risk
• Improvements in daytime sleepiness that correlate with hypoxic burden reduction, independent of AHI or arousal index changes
• Meaningful hypoxic burden improvements in at least 50% of AHI non-responders, supporting its role as a complementary biomarker
• Hypoxic burden is a measure of the total impact of oxygen desaturation events during sleep, integrating the depth, duration, and frequency of these events to quantify sleep apnea severity
  
  

These findings reinforce hypoxic burden as an emerging and clinically relevant endpoint and align with a growing number of studies evaluating cardiovascular outcomes in patients treated with Inspire therapy versus Continuous Positive Airway Pressure (CPAP) and untreated populations.

The second article from Dr. Nayak² compared clinical outcomes between HNS and CPAP in OSA patients using data from the TriNetX database and compared a matched group of 3,525 patients in each group (CPAP and Inspire therapy).

• OSA is linked to cardiovascular, metabolic, and neuropsychiatric morbidity
• The hypoglossal nerve stimulation cohort had significantly lower odds of stroke, myocardial infarction, atrial fibrillation/flutter, hypertensive crisis, pulmonary embolism, ventricular tachycardia, COPD exacerbation, acute kidney injury, hospitalization, acute heart failure, and others
• Hypoglossal nerve stimulation may offer systemic benefits and reduce healthcare burden compared to CPAP

PREDICTOR Study Publication

Inspire also announced the publication of the PREDICTOR study³, which identified body mass index and neck circumference as predictors of complete concentric collapse. These findings suggest that many patients may be screened for Inspire therapy eligibility without requiring drug-induced sleep endoscopy (DISE), potentially reducing diagnostic burden, time to treatment, and healthcare costs.

10:00 a.m. to 11:45 a.m. Tuesday, June 16, Exhibit Hall G

• Next-Generation Hypoglossal Nerve Stimulation Therapy for the Treatment of Obstructive Sleep Apnea: Final Study Results
  • 44 participants enrolled and successfully implanted with no device revisions or explants
  • Inspire V implant times decreased by 20.4% compared to the Inspire IV system
  • Respiratory sensing as demonstrated by Inspiratory Phase Overlap demonstrated superiority to the Inspire IV system at 87.1% vs. 79.4%
  • Mean AHI decrease of 25.5 events per hour from median AHI of 34.4 at baseline to 8.4
  • Mean adherence at 5.9 hours of usage per night

• Evaluation of a Next-Generation Unilateral Hypoglossal Nerve Stimulation with Respiratory Sensing Platform: Data from the Limited Market Release
  • Retrospective review of 41 patients implanted with Inspire V during a limited market release
  • Mean nightly therapy usage of 6.21 hours per night over the 30 days following in-lab post-titration sleep study
  • 97.6% of patients self-reported experiencing benefit from Inspire therapy

• Comprehensive Assessment of a 5,000 Patient Longitudinal Hypoglossal Nerve Stimulation Registry: Final Results of the ADHERE Registry
  • The ADHERE registry was designed to enroll 5,000 participants implanted with a hypoglossal nerve stimulation device throughout the U.S. and Europe

• A Target Trial Emulation of Hypoglossal Nerve Stimulation Therapy for OSA and Cardiovascular Outcomes – Late breaking abstract
  
  
  • Independent study using the Definitive Healthcare Atlas database in which 4,388 Inspire therapy patients were matched up with adherent CPAP patients, non-adherent CPAP patients, and those who remained untreated  
  • Compared to untreated patients, Inspire therapy was associated with the reduction of 8 of 9 MACE diagnoses while CPAP therapy was associated with the reduction of 6 of 9 MACE diagnoses
  • Inspire therapy is estimated to reduce the risk of MACE diagnoses compared to CPAP therapy and no treatment

• Real World Comparison of Patient Compliance and Efficacy Using Continuous Positive Airway Pressure versus Hypoglossal Nerve Stimulation
  • Independent retrospective study examined 45 patients from 2016 to 2024 with moderate to severe OSA initially treated with CPAP who later transitioned to Inspire therapy
  • Inspire therapy adherence was demonstrated to exceed CPAP adherence at 93% at 30 days as compared to 56% for CPAP and 91.7% at 90 days as compared to 56% for CPAP
  • Inspire therapy demonstrated approximately 65% greater median disease alleviation than CPAP, primarily through improved adherence over 90 days
  • Superior adherence may improve long-term cardiovascular and quality-of-life outcomes
