Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Change from baseline in nasal symptom severity | Follow-up visits at 6 weeks, 3, 6, 9, 12, 15, 18, 21, and 24 months post treatment | 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. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Patient-assessed improvement in nasal symptoms | Follow-up visits at 6 weeks, 3, 6, 9, 12, 15, 18, 21, and 24 months post treatment | 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). |
| Clinician-assessed improvement in nasal symptoms | Follow-up visit at 3 months post treatment | 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). |
