Aspire Medical Identifier:
First received: June 21, 2007
Last updated: December 22, 2009
Last verified: April 2009
The objective of this study is to assess the feasibility, safety and effectiveness of tongue stabilization using Aspire Medical Advance™ System for the treatment of obstructive sleep apnea (OSA). Success is defined as a statistically significant reduction in AHI measured by polysomnography (PSG) from baseline to 6 months.

Further study details as provided by Aspire Medical:

Primary Outcome Measures:
  • Demonstrate the feasibility of tongue stabilization using the Advance™ System. Product implantation and stabilization of the tongue using the Advance™system will be measured by Pharyngoscopy and Cephalogram [ Time Frame: 3 months ]
  • Evaluate the safety of the Advance™ System 3 Months after implantation. [ Time Frame: 3 months ]
  • Compare baseline and 6 month apnea-hypopnea indices as measured by PSG studies. [ Time Frame: 6 months ]

Secondary Outcome Measures:
  • Epworth Sleepiness Scale (ESS) measured at 3 Months post-implantation [ Time Frame: 3 months ]
  • Functional Outcomes of Sleep Questionnaire (FOSQ) measured at 3 Months post-implantation [ Time Frame: 3 months ]

Estimated Enrollment: 60
Study Start Date: February 2006
Study Completion Date: July 2009
Primary Completion Date: February 2009 (Final data collection date for primary outcome measure)
Intervention Details:
    Device: Aspire Medical Advance System
    The treatment includes a device that is surgically implanted in the tongue and lower jaw. The purpose of the implant is to prevent obstruction of the upper airway thereby improving breathing during sleep.
Detailed Description:

Obstructive sleep apnea (OSA) is a major health problem in the United States and can result in excessive daytime sleepiness and cardiovascular problems. The primary treatment for OSA today is continuous positive airway pressure (CPAP). Many patients however are unable to tolerate sleeping with a CPAP machine. Surgery is one of the main treatment options available today to these CPAP-intolerant patients. However, current methods of sleep surgery are painful, morbid, and/or lack decent effectiveness.

This trial will measure the effectiveness of the Advance System, an implantable medical device to treat OSA. In the trial, patients who meet the study entry criteria receive a baseline sleep study (PSG). The Advance System is then implanted and 6 months after implantation, another PSG is performed. The trial will compare the baseline and the 6 month apnea-hypopnea indices


Ages Eligible for Study:   20 Years to 65 Years   (Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Documented diagnosis of obstructive sleep apnea with AHI 15-50 measured within a year prior to enrollment with no major change in BMI
  • Bewteen 20 and 65 years old
  • Body Mass Index (BMI) ≤ 32
  • Patient has been offered CPAP and has refused or failed to continue CPAP treatment
  • Identified evidence of airway collapse, primarily at the base of the tongue
  • Signed informed consent to participate in this clinical study

Exclusion Criteria:

  • Prior OSA surgery except tonsillectomy, nasal surgery and uvulopalatopharyngoplasty; no airway surgery within 3 months prior to enrollment.
  • Airway collapse at the level of the soft palate (palatal collapse).
  • Enlarged tonsils (3+ and 4+)
  • Anatomy unable to accommodate the implant
  • Severe mandibular deficiency/retrognathia
  • Unable and/or not willing to comply with treatment follow-up requirements.
  • Pregnancy. (Female subjects of childbearing potential must have a negative pregnancy test prior to enrollment and should maintain adequate contraception during the study)
  • Breastfeeding women
  • Active systemic infection
  • Allergy to any medication used during implantation
  • Previous history of neck or upper respiratory tract cancer
  • History of radiation therapy to neck or upper respiratory tract
  • Dysphagia
  • Major cardiovascular and pulmonary disorders
  • Other medical, social or psychological problems that, in the opinion of the investigator, preclude them from receiving this treatment and the procedures and evaluations pre- and post-treatment
  • Enrollment in another pharmacological or medical device study that may effect or bias the results of this clinical study
