Nasal Airway Obstruction

Keywords

Nasal obstruction, NAO, Nasal valve dysfunction, Nasal airway obstruction

Brief summary

The purpose of this study is to compare the Vivaer procedure with radiofrequency (RF) energy to sham procedure for treatment of nasal airway obstruction (NAO).

Detailed description

The purpose of this study is to compare the Vivaer procedure for treatment of nasal airway obstruction (NAO) with a sham procedure that simulates the actual procedure as closely as possible absent the delivery of radiofrequency (RF) energy to the nasal tissue.

Interventions

The Vivaer procedure will be performed in the study clinic using the Vivaer ARC Stylus and Aerin Console. The Vivaer ARC Stylus is a disposable handheld device capable of delivering bipolar radiofrequency energy to tissue when connected to the Aerin Console radiofrequency generating device. Participants in this study will undergo bilateral treatment of the nasal valves in a single study session.

DEVICESham

The sham control procedure will be performed in the study clinic using the Vivaer ARC Stylus while audible sounds that accurately simulate the Aerin Console's active treatment are produced even though RF energy is not being generated or delivered. All other aspects of the procedure will be the same as used for the active treatment, including administration of anesthetic agent(s).

Inclusion criteria

1. Age 18 to 85 years (inclusively). 2. Willing and able to provide informed consent. 3. Willing and able to comply with the subject-specific requirements outlined in the Study Protocol. 4. Seeking treatment for nasal obstruction and willing to undergo an office-based procedure. 5. Baseline Nasal Obstruction Symptom Evaluation (NOSE) Scale score ≥ 55. 6. Nasal valve is a primary or significant contributor to the patient's nasal obstruction as determined by the study investigator (based on clinical presentation, physical examination, nasal endoscopy, etc.) and the patient has a positive response to any of the following temporary measures (based on patient history or office exam): * Use of external nasal dilator strips (eg, Breathe Right Strips) * Use of internal nasal dilator cones * Modified Cottle Maneuver (manual elevation of the lateral nasal wall using a small instrument or cotton-tipped applicator to open the nasal valve) * Cottle Maneuver (manual lateral retraction of the cheek to open the nasal valve) 7. Dissatisfaction with medical management as judged by the patient. Defined as failed medical therapy (eg, decongestants, antihistamines, and/or nasal sprays for an appropriate period of time), but a positive response to internal or external nasal dilators.

Exclusion criteria

1. Prior surgery of the lateral nasal wall, including cephalic resection of the lower lateral cartilage, dome division or suture plication, alar graft or spreader graft placement. 2. Rhinoplasty, septoplasty, inferior turbinate reduction or functional endoscopic sinus surgery (FESS) within the preceding 3 months. 3. Severe case of any of the following: septal deviation, turbinate hypertrophy, polyps, or ptotic nose tip believed to be the primary contributor to the patient's nasal obstruction symptoms and warranting surgical intervention. 4. Any adjunctive surgical nasal procedure planned on the same day or within 6 months after the Vivaer procedure. 5. Known or suspected to be pregnant or is lactating. 6. Participating in another clinical research study. 7.

Nasal Obstruction Symptom Evaluation (NOSE) Scale - 3 Month Responder Rate3 months visit following the study procedure.The Nasal Obstruction Symptom Evaluation (NOSE) Scale is a patient self-reported questionnaire consisting of 5 symptoms of nasal obstruction: nasal congestion, nasal blockage, trouble breathing, trouble sleeping, and getting enough air during exercise. Patients will report over the past 1 month how much the symptoms have been a problem. Total score ranges from 0 to 100, where higher scores indicate worse obstruction. Severity of symptoms can be classified as mild (range, 5-25), moderate (range, 30-50), severe (range, 55-75), or extreme (range, 80-100) nasal obstruction, based on responses.

Active Treament Arm - Vivaer Procedure Only
The Vivaer procedure will be performed in the study clinic using the Vivaer ARC Stylus and Aerin Console. The Vivaer ARC Stylus is a disposable handheld device capable of delivering bipolar radiofrequency energy to tissue when connected to the Aerin Console radiofrequency generating device. Participants in this study will undergo bilateral treatment of the nasal valves in a single study session. Each side of the nose will be treated with up to four (4) non-overlapping applications of RF energy at the junction of the upper and lower lateral cartilage on the lateral nasal wall. Treatment settings to be used are: temperature 60° C, power 4 watts, treatment time 18 seconds, and cooling time 12 seconds. No repeat (touch up) procedures will be permitted after the initial procedure through the end of the study (24 months).

Nasal Obstruction Symptom Evaluation (NOSE) Scale - 3 Month Responder Rate

The Nasal Obstruction Symptom Evaluation (NOSE) Scale is a patient self-reported questionnaire consisting of 5 symptoms of nasal obstruction: nasal congestion, nasal blockage, trouble breathing, trouble sleeping, and getting enough air during exercise. Patients will report over the past 1 month how much the symptoms have been a problem. Total score ranges from 0 to 100, where higher scores indicate worse obstruction. Severity of symptoms can be classified as mild (range, 5-25), moderate (range, 30-50), severe (range, 55-75), or extreme (range, 80-100) nasal obstruction, based on responses.

Time frame: 3 months visit following the study procedure.

Population: The percentage of patients designated responders, defined as 20% or greater improvement (decrease) in Nasal Obstruction Symptom Evaluation (NOSE)Scale score or 1 or greater NOSE Scale severity category improvement from baseline. Error bars indicate 95% CIs.

The NOSE Scale is a validated disease-specific health status instrument used by clinicians to measure the outcome of patients treated for nasal obstruction. The NOSE Scale consists of 5 items, each scored using a 5-point Likert scale to make a total score range of 0 through 100, where higher scores indicate worse obstruction. Severity of symptoms can be classified as range, 5-25), range, 30-50), severe (range, 55-75), or extreme (range, 80-100) nasal obstruction, based on responses to the NOSE survey. These data represents percent improvement in NOSE Scale score from baseline at 12 months

Time frame: 12 Month

Population: The combined active treatment group contains patients from the index active treatment arm and the crossover active treatment arm. The term baseline in the index active treatment arm refers to the out-come measure value prior to original active treatment procedure, and in the case of the crossover active treatment arm, baseline refers to the value reported at the time of requalification for crossover.

The NOSE Scale consists of 5 items, each scored using a 5-point Likert scale to make a total score range of 0 through 100, where higher scores indicate worse obstruction. Severity of symptoms can be classified as range, 5-25), (range, 30-50), severe (range, 55-75), or extreme (range, 80-100) nasal obstruction, based on responses to the NOSE survey. Measurement is # improvement in NOSE Scale score from baseline, the lower the score the less obstruction or a change to lower score indicates improvement in nasal airway obstruction.
