Brief Summary

The CLARITY Study is a prospective, single-arm, multicenter safety and efficacy study of the Neurent Medical NEUROMARK System in subjects with chronic rhinitis.

Conditions

Chronic Rhinitis

Keywords

Rhinitis

Outcome Measures

Primary Outcomes (3)

• Number of Participants With Device- or Procedure-related Serious Adverse Events (SAEs) Within 1 Month

  SAEs were defined per ICH-GCP (E6). This measure includes all SAEs assessed by the investigator as related to the device and/or procedure within 1 month post-procedure.

  1 month

• Mean Change From Baseline in VAS Nasal Symptom Score (NSS) for Rhinorrhea at 3 Months

  The Visual Analog Scale Nasal Symptom Score (VAS NSS) is a patient-reported outcome measure of nasal symptom severity. Each symptom item is scored on a scale of 0 to 10, where 0 indicates no symptoms and 10 indicates the worst possible symptoms; higher scores indicate worse outcomes. This measure reports the mean change from baseline to 3 months in VAS NSS for \[rhinorrhea / nasal congestion\]. A negative change from baseline indicates improvement.

  3 months

• Mean Change From Baseline in VAS Nasal Symptom Score (NSS) for Nasal Congestion at 3 Months

  The Visual Analog Scale Nasal Symptom Score (VAS NSS) is a patient-reported outcome measure of nasal symptom severity. Each symptom item is scored on a scale of 0 to 10, where 0 indicates no symptoms and 10 indicates the worst possible symptoms; higher scores indicate worse outcomes. This measure reports the mean change from baseline to 3 months in VAS NSS for \[rhinorrhea / nasal congestion\]. A negative change from baseline indicates improvement.

EXPERIMENTAL

Subjects will undergo treatment with the NEUROMARK System

Device: NEUROMARK System

Interventions

NEUROMARK System DEVICE

The NEUROMARK™ System is indicated for use in otorhinolaryngology (ENT) surgery for creation of radiofrequency (RF) lesions to disrupt posterior nasal nerves in patients with chronic rhinitis.

Eligibility Criteria

• Age: 18 Years+
• Sex: all
• Healthy Volunteers: No
• Age Groups: Adult (18-64), Older Adult (65+)

You may qualify if:

• Subject provides written informed consent, including authorization to release health information.
• Subject is 18 years of age or older at the time of consent.
• Subject has provided a negative pregnancy test (if subject is a woman of childbearing potential (WOCBP).
• Subject WOCBP must be practicing and willing to continue an effective method of birth control during the course of the study.
• Confirmation of moderate to severe symptoms of rhinorrhea. (VAS NSS score for runny nose ≥ 5.0 and rTNSS score for runny nose ≥ 2).
• Confirmation of mild to severe symptoms of nasal congestion. (VAS NSS score ≥ 2.5 for stuffy nose (congestion) and rTNSS score of ≥ 1).
• Confirmation that the total combined VAS NSS score is ≥ 10 for nasal congestion and runny nose.
• Subjects stated willingness to comply with all study procedures, post- treatment care and availability for the duration of the study follow up of 1 year.
• Subject tests negative for active COVID-19 at the start of study screening and continues to be free from COVID-19 symptoms until the time of enrollment/treatment.
• Subject understands and agrees to follow local COVID-19 restrictions (social distancing, face mask, etc.).
• Nasal anatomy appropriate to receive the NEUROMARK™ System.
• Subject is experiencing long term chronic rhinitis. Subject has been experiencing symptoms of rhinitis for at least 6 months prior to enrollment, defined as: rhinorrhea, anterior runny nose AND congestion, blockage (stuffy nose, obstruction).

You may not qualify if:

• Subject has clinically significant anatomic obstruction that limits access to the posterior nose as determined by the Study Investigator such as severe septal deviation, prior surgical considerations, cleft palate, nasal polyps, or sino-nasal tumor.
• Subject has an active nasal or sinus infection at the time of treatment.
• Subject has a diagnosis of Atrophic Rhinitis.
• Subject has a Lund-Mackay score \>3 during the screening phase, an active history of chronic sinusitis (within the last year).
• Subject has a septal perforation or nasal mucosal erosion/ulceration.
• Subject experiences numbness of the soft palate, excessive dry eye, excessive dry nose, or other indication of neuro/nerve compromise in the sino-nasal anatomy.
• Subject has had prior sinus or nasal surgery that may prevent access or proper placement of the NEUROMARK™ System.
• Subject has had prior head or neck irradiation (head/neck cancer therapy).
• Subject has an allergy or intolerance to anaesthetic agent or other study-required materials.
• Subject is taking anticoagulant medication or 325 mg aspirin that cannot be discontinued before the procedure and for the length of the study.
• Subject has a history of nasal manifestation of rheumatic disease.
• Subject has started a new sino-nasal medication regimen within 4 weeks prior to treatment (i.e. antihistamines, cromolyn, leukotriene receptor antagonists, inhaled or systemic steroids, anticholinergics, expectorants, decongestants) that, per the manufacturer's labelling, has not yet stabilized.
• Subject has uncontrolled Hypothyroidism.
• Subject has uncontrolled Hypertension (stage 2 or higher).
• Subject is an active smoker or has been a smoker within the last 6 months (patient reported).
