What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Change From Baseline in Symptom Severity

    Effectiveness will be assessed by the mean change in nasal symptoms using the 4-symptom rTNSS (reflective Total Nasal Symptom Score). The rTNSS is the sum of 4 individual patient-rated symptom scores for rhinorrhea, nasal congestion, nasal itching, and sneezing, each evaluated using a scale of 0=None, 1=Mild, 2=Moderate, and 3=Severe. The rTNSS has a possible score of 0-12. The reflective scores are based on the participant's evaluation of symptom severity over the preceding 24 hours. A change of 1 or more is considered the minimum clinically important difference.

    Measured: 90 days post treatment

  2. Device- and/or Procedure-related Serious Adverse Events

    Safety will be evaluated based on the frequency of device- and/or procedure-related serious adverse events

    Measured: 90 days post treatment

Secondary outcomes (1)
  1. Change From Baseline in the Rhinoconjunctivitis Quality of Life Questionnaire (RQLQ)

    The RQLQ is a validated quality of life questionnaire that evaluates functional problems associated with rhinitis. The questionnaire assess 7 domains: activities, sleep, nose symptoms, eye symptoms, non nose/eye symptoms, practical problems, and emotional function. Each question is scores on a 7-point scale (0=not impaired at all, 6=severely impaired). A domain and total scores are based on the mean of all answered items in that domain resulting in domain or total scores ranging from 0 to 6. An average change on 0.5 or more is considered a minimal clinically important difference.

    Measured: 90 days post treatment
