NCT03772405

Brief Summary

The aim of this study is to assess if a physical barrier, created by the nasal gel Nascum®- Plus, is able to prevent or minimize the induction of nasal symptoms during allergen challenge in the Fraunhofer Allergen Challenge Chamber (ACC). Furthermore, the effect on soluble and cellular inflammatory markers induced by the allergic reaction will be assessed. Nascum®-Plus contains no active pharmaceutical ingredient, only monographed pharmaceutical excipients.

Outcome Measures

Primary Outcomes (1)

  • Total Nasal Symptom Score (TNSS)

    Change of TNSS assessed during grass pollen challenge in ACC

    pre start of challenge and every 20 minutes during 4 hours challenge

Study Arms (1)

Nascum Plus and ACC

EXPERIMENTAL

In a cross-over design, patients are exposed to pollen in the ACC twice for 4 hours each 3 weeks apart. Subjects will receive treatment with Nascum Plus either 5 minutes before the first or the second 4 hour pollen challenge.

Drug: Nascum PlusOther: ACC

Eligibility Criteria

Age18 Years - 65 Years
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • \. Able and willing to give written informed consent.
  • Of childbearing potential and using a highly effective method of contraception during the entire study (vasectomised partner, sexual abstinence - the lifestyle of the female should be such that there is complete abstinence from intercourse from two weeks prior to the first dose of study medication until at least 72 hours after treatment -, implants, injectables, combined oral contraceptives, hormonal IUDs or double-barrier methods, i.e. any double combination of IUD, condom with spermicidal gel, diaphragm, sponge, and cervical cap).
  • \. Body mass index between 18 and 32 kg/m²
  • \. History of seasonal allergic rhinitis to grass pollen
  • \. Positive skin prick test for Dactylis glomerata pollen at screening or within 12 months prior to the screening visit.
  • \. Normal lung function Forced Expiratory Volume in one second (FEV1) ≥ 80 % pred and FEV1/Forced Vital Capacity (FVC) \>70% at screening
  • \. Adequate level of rhinitis symptoms in a grass pollen challenge, defined as a Total Nasal Symptom Score (TNSS) of at least 6 (of 12) within the 2-hour grass pollen challenge at performed at the Screening ACC visit (V2).
  • \. TNSS of 3 prior to entering the pollen chamber at screening.
  • \. Non-smokers or ex-smokers since at least 6 months with a history of less than 10 pack years

You may not qualify if:

  • \. Any clinically relevant abnormal findings in physical examination, clinical chemistry, hematology, urine analysis, vital signs, lung function or Electrocardiogram (ECG) at screening visit , which, in the opinion of the investigator, may either put the subject at risk because of participation in the study or may influence the results of the study, or the subject's ability to participate in the study
  • \. Past or present disease, which as judged by the investigator, may affect the outcome of this study. These diseases include, but are not limited to, cardiovascular disease, malignancy, hepatic disease, renal disease, hematological disease, neurological disease, endocrine disease or pulmonary disease (including but not confined to chronic bronchitis, emphysema, tuberculosis, bronchiectasis or cystic fibrosis).
  • \. History of an acute infection four weeks prior to the informed consent visit
  • \. Specific Immunotherapy (SIT) within 2 years prior to the study
  • \. Rhinitis of other cause, chronic sinusitis or rhinitis or sinusitis in the last 14 days before entering the study
  • \. Asthma requiring more than inhaled short-acting beta-2 agonists.
  • \. Conditions or factors, which would make the subject unlikely to be able to stay in the Fraunhofer ACC for 4 hours.
  • \. Any contraindication for adrenalin use (e.g. use of local and systemic beta-blockers, angiotensin-converting-enzyme (ACE) inhibitors
  • \. Treatment with antipsychotic medications with antihistaminic effect (e.g. chlorpromazine, levomepromazine, clozapine, olanzapine, tioridazine)
  • \. Use of any medications according to section 8.2 in the period indicated before allergen challenge
  • \. Participation in another clinical trial 30 days prior to enrollment.
  • \. History of drug or alcohol abuse
  • \. Risk of non-compliance with study procedures
  • \. Suspected inability to understand the protocol requirements, instructions and study-related restrictions, the nature, scope, and possible consequences of the study
