About this study

The NOVOCLEAR™ Device is a radiofrequency-based hand-held device intended to treat chronic rhinitis by delivering pulsed field energy to soft tissues in the nasal airway, including the posterior nasal nerve distribution. The NOVOCLEAR™ Device is used with the AVENTIX™ PFX System. The AVENTIX™ PFX System is a radiofrequency-based electrosurgical system designed to deliver non-thermal pulsed field energy to the targeted tissue.

This is a non-significant risk, prospective, multi-center, single arm study to evaluate the safety, effectiveness and tolerability of the NOVOCLEAR™ Device used with the AVENTIX™ PFX System.

Who can participate

Healthy volunteers accepted: No

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • The subject is 18 to 85 years of age.
  • The subject has had symptoms of chronic rhinitis for greater than 6 months with insufficient response to nasal steroids.
  • The subject has an rTNSS total score of ≥ 6.
  • The subject has had moderate to severe symptoms of rhinorrhea and/or nasal congestion (rTNSS rating of 2 or 3 for rhinorrhea and 1, 2, or 3 for congestion)
  • The subject is able and willing to provide written informed consent and comply with the protocol requirements.

Exclusion criteria

  • The subject has clinically significant anatomic obstructions on either side that limit access to the posterior nose, including severe septal deviation, nasal polyps, and sinonasal tumor
  • The subject has a septal perforation
  • The subject has had prior sinus or nasal surgery on either side that significantly alters the anatomy of the posterior nose.
  • The subject had had previous surgery of the PNN for chronic rhinitis.
  • The subject has had prior head or neck irradiation
  • The subject has an active or chronic nasal or sinus infection
  • The subject has active coagulation disorder, or the patient is receiving anticoagulants
  • The subject has a history of dry eye or dry nose symptoms
  • Patient has rhinitis medicamentosa
  • The subject has ocular allergic symptoms
  • The subject has a history of nose bleeds
  • The subject has electrically sensitive implants (e.g. cochlear implants, pacemakers, defibrillators)
  • The subject is pregnant or lactating
  • The subject is participating in another clinical research study
  • The subject has an allergy or intolerance to anesthetic agent
  • Any physical condition that, in the Investigator's opinion, would prevent adequate study participation or pose an increased risk

Treatment and study plan

NOVOCLEAR™ Device

Device

Pulsed field energy applied to soft tissues in the nasal airway, including the posterior nasal nerve distribution.

Primary outcomes

  1. Mean change in Reflective Total Nasal Symptom Score (rTNSS) at 90 days compared to baseline.

    Time frame: 90 days

    The rTNSS is the sum of 4 individual subject-assessed symptom scores for rhinorrhea, nasal congestion, nasal itching, and sneezing, each evaluated using a scale of 0=None, 1=Mild, 2=Moderate, or 3=Severe. Total scores range from 0 to 12. A higher score indicates increased symptom severity.

  2. Proportion of subjects with device and/or procedure-related serious adverse events through 90 days

    Time frame: 90 days

    Characterization of the type and frequency of study device and/or study procedure-related adverse events reported during or following the study procedure through 90 days follow-up.

Secondary outcomes

  1. Mean change in rTNSS at 7 days compared to baseline

    Time frame: 7 days

    The rTNSS is the sum of 4 individual subject-assessed symptom scores for rhinorrhea, nasal congestion, nasal itching, and sneezing, each evaluated using a scale of 0=None, 1=Mild, 2=Moderate, or 3=Severe. Total scores range from 0 to 12. A higher score indicates increased symptom severity.

  2. Mean change in rTNSS at 14 days compared to baseline

    Time frame: 14 days

    The rTNSS is the sum of 4 individual subject-assessed symptom scores for rhinorrhea, nasal congestion, nasal itching, and sneezing, each evaluated using a scale of 0=None, 1=Mild, 2=Moderate, or 3=Severe. Total scores range from 0 to 12. A higher score indicates increased symptom severity.

  3. Mean change in rTNSS at 30 days compared to baseline

    Time frame: 30 days

    The rTNSS is the sum of 4 individual subject-assessed symptom scores for rhinorrhea, nasal congestion, nasal itching, and sneezing, each evaluated using a scale of 0=None, 1=Mild, 2=Moderate, or 3=Severe. Total scores range from 0 to 12. A higher score indicates increased symptom severity.

  4. Mean change in rTNSS at 6 months compared to baseline

    Time frame: 6 months

    The rTNSS is the sum of 4 individual subject-assessed symptom scores for rhinorrhea, nasal congestion, nasal itching, and sneezing, each evaluated using a scale of 0=None, 1=Mild, 2=Moderate, or 3=Severe. Total scores range from 0 to 12. A higher score indicates increased symptom severity.

  5. Mean change in rTNSS at 1 year compared to baseline

    Time frame: 1 year

    The rTNSS is the sum of 4 individual subject-assessed symptom scores for rhinorrhea, nasal congestion, nasal itching, and sneezing, each evaluated using a scale of 0=None, 1=Mild, 2=Moderate, or 3=Severe. Total scores range from 0 to 12. A higher score indicates increased symptom severity.

  6. Mean procedure tolerability using a Visual Analogue Scale (VAS) at post-procedure

    Time frame: Post-procedure

    Immediately after the study procedure, subjects will be asked to rate the pain they experienced in their nasal cavity(ies) during the procedure using a 100 mm visual analogue scale with 0 mm representing no pain and 100 mm representing worst pain imaginable.

  7. Subject satisfaction at 90 days

    Time frame: 90 days

    Subjects will be asked two questions regarding their satisfaction with the study procedure.

    The first question asks; How satisfied with your procedure are you?; with the following five response options: very satisfied, satisfied, neutral, unsatisfied, or very unsatisfied.

    The second question asks; How likely are you to refer a friend for this procedure?; with the following five response options: very likely, likely, neutral, unlikely, or very unlikely.
