Study summary

Proof-of-concept study with a novel nasal spray in chronic rhinitis or chronic sinusitis. The study will involve 25 patients completing the study for a per protocol analysis.

Read the detailed description

Visit 1 (Day 0): Screening visit. Assessment of outcome measures

Visit 2 (Day 7): Enrollment visit after a 1-week wash-out period. Enrolled to the Study are only patients who show a severe enough and stable disease (SNOT score >20 and change of SNOT score \<15% compared to Visit 1, respectively).

Visit 3 (Day 21): Assessment of outcome measures after 2-week treatment phase

Visit 4 (Day 49): Follow-up visit

Study arms

  • Experimental
    Jantar-1 (JT-1), 7% (w/w) aqueous solution

    Dosing regimen: ad libitum between at least 2 doses, in the morning and in the evening, and at most 10 doses per day. A dose corresponds to two strokes of 100ul each per nostril.

    Drug: JT-1

Interventions

  • DrugJT-1

    JT-1 is a physiological salt with recently detected pharmacological properties that warrant testing for its therapeutic potential in chronic rhinitis and chronic sinusitis.

What researchers measure

Primary outcomes

  1. Change of Sino-Nasal Outcome Test (SNOT) score from baseline

    Questionnaire of 22 questions on the subjective clinical symptoms of chronic rhinitis and chronic sinusitis, score between 0 (no symptoms) and 120 (worst possible disease)

    Time frame: Baseline (enrollment visit) and after 2-week treatment phase

Secondary outcomes

  1. Change of Peak Nasal Inspiratory Flow (PNIF) from baseline

    The PNIF meter measures the nasal airway patency in L/min.

    Time frame: Baseline (enrollment visit) and after 2-week treatment phase

  2. Change of Smell Diskettes Olfactory Test from baseline

    Standardized 8-item odor (forced multiple choice) identification test (score of 0 to 8 correct answers)

    Time frame: Baseline (enrollment visit) and after 2-week treatment phase

  3. Change of Visual Analog Scale (VAS) of Headache Intensity

    VAS is a method to measure the symptom severity. Patients mark a spot on a 100mm long line between no pain (left end) and worst possible pain (right end) which corresponds to their current pain level. The distance between the left end and the mark measures the subjective severity of pain. Minimum value: 0; maximum value: 100. A lower score after treatment compared to baseline means improved outcome.

    Time frame: Baseline (enrollment visit) and after 2-week treatment phase

  4. Change of Visual Analog Scale (VAS) of Nasal Discomfort

    VAS is a method to measure the symptom severity. Patients mark a spot on a 100mm long line between no discomfort (left end) and worst possible discomfort (right end) which corresponds to their current level of discomfort. The distance between the left end and the mark measures the subjective severity of nasal discomfort. Minimum value: 0; maximum value: 100. A lower score after treatment compared to baseline means improved outcome.

    Time frame: Baseline (enrollment visit) and after 2-week treatment phase
