Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Change from baseline in nasal symptom severity	Effectiveness will be assessed by the change from baseline in nasal symptoms using the TNSS (Total Nasal Symptom Score). The TNSS is a patient-reported assessment of 4 symptom scores for rhinorrhea (runny nose), nasal congestion, nasal itching, and sneezing. Each symptom is rated on a scale of 0 (none) to 3 (severe). The symptom scores are summed to give a total TNSS score that can range from 0 to 12.	Follow-up visits at 6 weeks, 3, 6, 9, 12, 15, 18, 21, and 24 months post treatment
Secondary	Patient-assessed improvement in nasal symptoms	Percentage of participants reporting their change from baseline as minimally improved, much improved, or very much improved using the Patient Global Impression of Change (PGIC) assessment. The PGIC has patients evaluate their improvement over baseline on a scale from 1 (very much improved) to 7 (very much worse).	Follow-up visits at 6 weeks, 3, 6, 9, 12, 15, 18, 21, and 24 months post treatment
Secondary	Clinician-assessed improvement in nasal symptoms	Percentage of clinicians reporting their participants change in nasal symptoms from baseline as minimally improved, much improved, or very much improved using the Clinical Global Impression - Improvement (CGI-I) assessment. The CGI-I has clinicians rate their patient's improvement over baseline on a scale from 1 (very much improved) to 7 (very much worse).	Follow-up visit at 3 months post treatment
