Study 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).

Read the 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.

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):

    Vivaer Procedure

    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).

    Device: Vivaer ARC Stylus

  • Sham comparator
    Sham Control Procedure

    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).

What researchers measure

Primary outcomes

  1. 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.

This study will measure the mean change in NOSE Scale from baseline to 3 months after procedure.

    Time frame: Change from Baseline to 3 months following the study procedure.

  2. Percentage of Participants With Treatment Related Events (Safety) - Through 3 Months

    Characterizing the type and frequency of adverse events reported. Subjects will be asked about possible side effects or adverse experiences related to the study procedure at each follow up visit. All events will be documented and identified as to its relationship and level of relatedness to the study device and/or study procedure. Date of onset, seriousness, intensity, duration and outcome will be documented.

    Time frame: At or following the study procedure up to to 3 months.

Limitations and caveats
Medication use was not dictated by the protocol and could affect symptom relief; Data presented are through 12 months and continued follow-up will provide additional data on long term durability. Only subjects with nasal valve collapse as primary NAO were enrolled, but some subjects may have other contributors - for this reason, eligibility exclusion criteria should be considered with results.

Participant flow

Particpants were recruited based on physican referral at 16 academic medical centers and clinics between August 12,2020 and December 28, 2020. The First Participant enrolled on August 12, 2020 and the last participant enrolled on December 28, 2020.

The ESS evaluates the self-reported likelihood of dozing or falling asleep in 8 daytime situations with likelihood rated No Chance (0), Slight (1), Moderate (2), or High Chance (3).40 The total of the scores across the 8 questions can be categorized and interpreted as: 0-7 It is unlikely that you are abnormally sleepy. 8-9 You have an average amount of daytime sleepiness. 10-15 You may be excessively sleepy depending on the situation. You may want to consider seeking medical attention. 16-24 You are excessively sleepy and should consider seeking medical attention. The mean change in Epworth Sleepiness Scale score from baseline was also analyzed at 3-, 6-, and 12-months post procedure. NOSE Scale and Epworth Sleepiness Scale data were also collected at 1 month post procedure. Data reported here is from 3M as 12M was not included because of the long-term follow-up focus of the report.

Baseline characteristics

A total of 119 eligible patients were randomized. Assignment with 78 in the active treatment arm and 41 in the sham-control arm. One patient in the active treatment arm withdrew consent before treatment. One patient in the sham-control arm was lost to follow-up before the 3-month visit (primary endpoint).Therefore, a total of 117 patients (77 active treatment and40 sham control) were included in the analysis of the 3-month primary endpoint.
