Paclitaxel-Coated Nasal Balloon for the Treatment of Recurrent Chronic Rhinosinusitis With or Without Nasal Polyps (FIH)
Study Details
Study Description
Brief Summary
It is a first in human (FIH) study to evaluate safety, and potential efficacy of Airiver Nasal DCB in the treatment of recurrent CRSwNP or CRSsNP.
Participants will receive AIRIVER Nasal drug-coated balloon treatment.

Detailed Description
Paclitaxel coated balloon is designed to offer both mechanical dilation of nasal obstruction and local drug effect for underlying inflammatory disorder and cell hyperplasia. It is hypothesized that Airiver Nasal drug-coated balloon (DCB) will improve patient outcome and as an adjunct to standard of care, will improve nasal patency than the standard of care alone. This is a prospective, single arm, first in human (FIH) study.
Study Design
Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Experimental: Single arm treated by Airiver Nasal DCB Subjects with recurrent symptomatic nasal obstruction will be treated by Airiver Nasal Drug Coated Balloon (DCB) Catheter at the index procedure. The balloon is coated with a paclitaxel drug (3.5ug/mm2). |
Combination Product: Airiver Nasal Drug Coated Balloon (DCB) Catheter.
The balloon is coated with a paclitaxel drug (3.5ug/mm2).

Outcome Measures
Primary Outcome Measures
- Primary safety: Freedom from major device related adverse events (MADE) post index procedure assessed by the proportion of subjects free from the primary safety event through 30 days. [30 days]
Subjects failing any component of the primary safety endpoint will be considered a safety failure, and subjects who remain event free through 30 days will be considered safety successes. MADE is defined as: 1) Cerebrospinal fluid (CSF) leak, 2) Severe epistaxis (nasal bleeding) requiring intervention other than packing, 3) Eye complication requiring surgical treatment, 4) Paclitaxel related nasal mucosal disorder.
- Primary efficacy: Freedom from target lesion reintervention due to recurrence of CRS without nasal polyposis or CRS with nasal polyposis (retuning to baseline symptoms or worse) through 6 months. [6 months]
assessed by Kaplan-Meier survival analysis of the incidence of subjects free from symptom-driven TLR.
Secondary Outcome Measures
- Incidence of, and time to symptom-driven reintervention [12 months]
assessed by Kaplan-Meier survival analysis of the incidence of subjects free from symptom-driven TLR
- Change in patient reported 22-item Sino-Nasal Outcome Test (SNOT-22) from the baseline [12 months]
Total SNOT 22 score is between 0 to 110. Higher scores indicate worse rhinosinusitis.
- Change in Lund-Kennedy Endoscopic Scores from the baseline [12 months]
The scores range is from 0 to 20. Higher scores indicate worse observed disease.
- Change in Lund-Mackay computed tomography (LMK-CT) score from the baseline [12 months.]
The score range is from 0 to 24. Higher scores indicate worse disease severity.
- Change of Health-related quality -of- life (HRQL) from the baseline (Euro-QOL-5D questionnaire) [12 months]
The EQ-5D essentially consists of 2 parts: the EQ-5D descriptive system and the EQ VAS. The EQ-5D descriptive system comprises 5 dimensions: mobility, self-care, usual activities, pain/discomfort and anxiety/depression. Each dimension has 5 levels: no problems, slight problems, moderate problems, severe problems, and extreme problems. The EQ VAS records the respondent's self-rated health on a vertical VAS. The EQ VAS 'thermometer' has scales of 100 (Best imaginable health state) at the top and 0 (Worst imaginable health state) at the bottom.
- Change in sense of smell using the University of Pennsylvania Smell Identification Test (UPSIT) from the baseline [12 months]
The score range is between 0-40. Higher scores indicate better smell function.
- Clinical pharmacokinetics of paclitaxel in 15 subjects [10 days]
Blood samples will be collected at baseline and post procedure at pre-designated time points and assessed for plasma paclitaxel concentrations.
- Change in Asthma Control Questionnaire-6 (ACQ-5) Scores from baseline for subjects with comorbid asthma [12 months]
A score of 0-6 is assigned to values for each criterion. The total ACQ score is the mean value calculated after adding the individual scores for each criterion. In general, patients with a score below 1.0 are likely to have adequately controlled asthma, above 1.0 their asthma is not likely to be well-controlled.
- Nasal DCB performance evaluation in index procedures [one day]
Device Performance will be assessed using a rating scale (1-5) to evaluate seven aspects of the test article. Higher scores indicate better performance.
