Objectives
Narrative objectives1 To assess the efficacy of transient Trichuris suis infestation of the gut on self-reported symptoms of allergic rhinitis and number of well-days among adults with allergic rhinitis
Basic objectives2 Others
Basic objectives -Others To assess the efficacy and safety of transient Trichuris suis infestation of the gut on allergic rhinitis and asthma assessed through self-reported disease activity, clinical skin and airway activity, and immunological activity among adults with allergic rhinitis.
Trial characteristics_1 Exploratory
Trial characteristics_2 Explanatory
Developmental phase Phase II

Assessment
Primary outcomes Daily score for symptoms of allergic rhinitis, and number of well days during the pollen season.
Key secondary outcomes Efficacy variables
Self-reported disease activity related to allergic rhinitis
a. Daily recording of use of medication for allergic rhinitis, calculated as a score during data management.
b. Daily score for all symptoms of allergic rhinitis on a 100mm visual analog scale (VAS).
c. Assessment at the end of the trial of all symptoms of allergic rhinitis during the trial when compared with symptoms during the previous pollen season.
d. Weekly score for quality of life using a validated Rhinitis Quality of Life Score.
Clinical skin and airway activity
e. Skin test reactivity to inhalant allergens.
f. Degree of airway inflammation measured by amount of exhaled nitrogen oxid into a Niox apparatus.
Immunological activity
g. Reactivity of specific IgE and level of specific IgG/IgG4 to inhalant allergens measured by ImmunoCAPT. Differential blood count and total histamine in serum.
h. Cytokines (IL-4, IL-5, IL-13, IL-10, TGFbeta, IFNgamma) measured as in vitro production from peripheral blood mononuclear cells in response to stimulation with allergens and Trichuris suis antigen (Subsample of 30 participants.
Efficacy and safety variables
Self-reported disease activity related to asthma and adverse events
i. Daily recording of use of medication for asthma, calculated as a score during data management.
j. Daily score for symptoms of asthma (safety variable).
k. Daily adverse events (safety variable)
Clinical airway activity
l. Daily lung function measured as forced expiratory volume 1 (FEV1, safety variable) and peak expiratory force (PEF) using a pocket flow-meter.
