A Trial to Evaluate a Device for the Treatment of OSA and Snoring

The Tongue Advancement Retainer Device is a device that was developed to treat subjects with
OSA and snoring. The purpose of this study is to evaluate initial safety and effectiveness
of this device in treating one or both conditions.

Inclusion Criteria:

- • Aged 18-65

- AHI greater than or equal to 10 but less than or equal to 60 (<10 AHI <60/hr)

- Complete set of lower anterior incisors with no evidence of periodontal disease
or mobility and the ability to floss between teeth

Additionally subjects will in the screening phase must:

- Tolerate the device when being fitted

- Used the device for >4 hours on at least two consecutive nights during the screening
period.

- Be able to reliably demonstrate proper installation of the device after fitting.

- Be willing to trial the device for a 4 week period

Exclusion Criteria:

- • Central sleep apnea events >10% of the total events

- Evidence of Cheyne stokes breathing

- Currently on treatment for OSA or OSA treatment discontinued less than 3 months
prior.

- Currently on regular treatment with prescription hypnosedatives or prescription
stimulants

- Very severe OSA, defined as AHI>60/hour and/or minimum oxygen saturation <75%

- Need for immediate initiation of treatment as assessed by physician (e.g.
Excessive sleepiness posing driving risk)

- Previous surgery to treat OSA (other than nasal surgery)

- Evidence of periodontal disease or tooth mobility

- Severe nasal obstruction or enlarged tonsils based on clinical assessment

- Unstable cardiovascular disease (untreated hypertension acceptable).

- Inability to tolerate oral device due to oral condition or claustrophobia as
determined by the study investigator

- Pregnant/Breast Feeding

- Any known factor or disease that might interfere with treatment compliance,
study conduct or interpretation of the results such as co-existent other sleep
disorder, psychiatric disease, history of non compliance to medical regimens, or
unwillingness to comply with study requirements.
