About this study

Official title: Prospective Trial of Paclitaxel-Coated Nasal Balloon for the Treatment of Recurrent Chronic Rhinosinusitis With or Without Nasal Polyps

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.

Read the 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.

Being tested
Airiver Nasal Drug Coated Balloon (DCB) Catheter.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Airiver Nasal Drug Coated Balloon (DCB) Catheter.Combination product

    The balloon is coated with a paclitaxel drug (3.5ug/mm2).

Study groups in NCT05883462
Study groupRoleWhat they receive
Single arm treated by Airiver Nasal DCBExperimentalSubjects 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).
Receives: Combination Product: Airiver Nasal Drug Coated Balloon (DCB) Catheter.

What is being measured

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

  1. 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.

    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.

    Measured: 30 days

  2. 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.

    assessed by Kaplan-Meier survival analysis of the incidence of subjects free from symptom-driven TLR.

    Measured: 6 months

Secondary outcomes (9)
  1. Incidence of, and time to symptom-driven reintervention

    assessed by Kaplan-Meier survival analysis of the incidence of subjects free from symptom-driven TLR

    Measured: 12 months

  2. Change in patient reported 22-item Sino-Nasal Outcome Test (SNOT-22) from the baseline

    Total SNOT 22 score is between 0 to 110. Higher scores indicate worse rhinosinusitis.

    Measured: 12 months

  3. Change in Lund-Kennedy Endoscopic Scores from the baseline

    The scores range is from 0 to 20. Higher scores indicate worse observed disease.

    Measured: 12 months

  4. Change in Lund-Mackay computed tomography (LMK-CT) score from the baseline

    The score range is from 0 to 24. Higher scores indicate worse disease severity.

    Measured: 12 months.

  5. Change of Health-related quality -of- life (HRQL) from the baseline (Euro-QOL-5D questionnaire)

    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.

    Measured: 12 months

  6. Change in sense of smell using the University of Pennsylvania Smell Identification Test (UPSIT) from the baseline

    The score range is between 0-40. Higher scores indicate better smell function.

    Measured: 12 months

  7. Clinical pharmacokinetics of paclitaxel in 15 subjects

    Blood samples will be collected at baseline and post procedure at pre-designated time points and assessed for plasma paclitaxel concentrations.

    Measured: 10 days

  8. Change in Asthma Control Questionnaire-6 (ACQ-5) Scores from baseline for subjects with comorbid asthma

    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.

    Measured: 12 months

  9. Nasal DCB performance evaluation in index procedures

    Device Performance will be assessed using a rating scale (1-5) to evaluate seven aspects of the test article. Higher scores indicate better performance.

    Measured: one day

Questions about this trial

What is this clinical trial studying?

A Early Phase 1 study testing Airiver Nasal Drug Coated Balloon (DCB) Catheter. in people with Chronic Rhinosinusitis, run by Airiver Medical, Inc. at 1 site in Paraguay.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 0 inclusion and 21 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: under way, not looking for participants, as of the sponsor's last update on 15 Dec 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Paraguay. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Early Phase 1 (sometimes called Phase 0) studies give a very small amount of a treatment to a few people, mainly to see how the body handles it.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

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. (time frame: 30 days). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 15 Dec 2025.
