Brief Summary:
The purpose of this clinical trial is to assess the safety and efficacy of SDX-3101 for treatment of adult patients with chronic rhinosinusitis without nasal polyps (CRSsNP) by investigating a vibration pattern of SDX-3101 compared to a control

Condition or disease Intervention/treatment Phase
Chronic Rhinosinusitis Without Nasal Polyps Device: Vibration Therapy Not Applicable

Detailed Description:

Chronic rhinosinusitis (CRS) is a common disease (e.g. 11% of adults in the UK report symptoms of CRS) leading to substantial health and socioeconomic burden with estimated healthcare costs in the USA of $772/patient/year (2011).

CRS is characterised by the long-term presence of multiple symptoms including facial pain/pressure in about 80% of CRS patients. Factors contributing to the pathophysiology of adult CRS include allergies, bacterial biofilms, asthma and exposure to various environmental pollutants. Computed tomography (CT) scans are often used to identify mucosal thickening and to identify any comorbid factors such as anatomic abnormalities.

It is known from the literature that low vibration frequency can improve blood flow, significantly reduce inflammation, and increase the fibroblast activity [13]. Therefore, SynDermix AG created the innovative high-technology, portable medical device SDX-3101 targeting a disease with high unmet medical need. The device offers a drug-free or eventually an add on treatment complying with the maximum demands of safety for the patients potentially avoiding undesirable drug effects or surgery. SDX-3101 is indicated for treatment of CRSsNP in adults

Arm Intervention/treatment
Experimental: Treatment
The applied therapeutic vibrations generated by an acoustic coil have a defined sweeping frequency range.
Device: Vibration Therapy
SDX-3101 is used for drug-free treatment of CRSsNP in adults.

Active Comparator: Control
A control device with a different vibration pattern will be used as comparator intervention
Device: Vibration Therapy
SDX-3101 is used for drug-free treatment of CRSsNP in adults.

Primary Outcome Measures :
  1. SNOT-20 GAV [ Time Frame: 12 weeks ]
    The primary endpoint is the change in subjective symptoms as quantified by the German validated disease-specific 20-item Sino-nasal Outcome Test (SNOT-20 GAV) after 12 weeks. Superiority is defined as more than minimal clinically important difference (MCID) of 8.9 points to active control of SNOT-20 score at 12 weeks.

Secondary Outcome Measures :
  1. Lund-Kennedy Score [ Time Frame: day 0, day 14, week 6, 12 and at 6, 9 and 12 months ]
    We use the Lund-Kennedy endoscopic scoring system to measure the patient's nasal cavity based on there were edema, vesicles, adhesions, scars and polyps

  2. Overall disease control [ Time Frame: day 14, week 6, 12 and at 6, 9 and 12 months ]
    Need for systemic medication, steroid or antibiotic, number of days

  3. Need for surgical intervention [ Time Frame: day 14, week 6, 12 and at 6, 9 and 12 months ]
    Capture surgical intervention

  4. Ability to perform normal activities [ Time Frame: day 0, day 14, week 6, 12 and at 6, 9 and 12 months, ]
    Measured with the SNOT-20 GAV

  5. Acceptability of treatment [ Time Frame: day 14, week 6, 12 and at 6, 9 and 12 months ]
    Measurement of Visual Analogue Scale 0 to 5, 0 is unacceptable to 5 fully accepted

  6. Overall score SNOT-20 [ Time Frame: day 0, day 14, week 6, 12 and at 6, 9 and 12 months ]
    The SNOT-20 has a maximum score of 100 and a minimum score of 0. Higher values represent a worse outcome

  7. Pain in the face [ Time Frame: day 0, day 14, week 6, 12 and at 6, 9 and 12 months ]
    Measured on a 4-point scale, (0=no symptoms; 1=mild symptoms present, but not troublesome; 2=moderate symptoms that were frequently troublesome but not sufficiently so to interfere with normal daily activities or sleep; 3=severe symptoms that interfered with normal daily activities or sleep)

  8. Global impression by investigator [ Time Frame: day 0, week 6, 12 and at 12 months, ]
    Measured with Visual Analogue Scale 0 to 10, 0 is unsatisfactory 10 is optimal outcome

Other Outcome Measures:
  1. Saccharine test [ Time Frame: day 0, week 6, 12 weeks and at 12 months ]
    Evaluate muco-ciliary clearance time

  2. Reduction in inflammatory markers [ Time Frame: day 0, day 14, week 6, 12 ]
    Assessed by Biomarkers: IL-1β, IL-2, IL-4, IL-10, IL-12 and IgE in nasal secretion

  3. Exhaled nasal Nitric Oxide (nNO) levels [ Time Frame: day 0, day 14, week 6, 12 and 12 months ]
    only in a subpopulation in selected site/s
