What researchers measure

Primary outcomes

  1. change in the combined symptom medication score (CSMS)

    The primary endpoint is the change in the total combined symptom medication score (CSMS) during the entire study period, determined from the rhinoconjunctivitis daily symptom score (dSS) and rhinoconjunctivitis daily medication score (dMS), averaged over the respective peak pollen season

    Time frame: once a year for 5 years

Secondary outcomes

  1. rhinoconjunctivitis daily medication score

    the changes in use of daily anti-allergic medication needed, averaged over the respective peak pollen season

    Time frame: once a year for 5 years

  2. rhinoconjunctivitis daily symptom score

    allergic symptoms and severity will be self-recorded by the subject in an eDiary on a daily basis during the pollen season, averaged over the respective peak pollen season

    Time frame: once a year for 5 years

  3. Rhinoconjunctivitis Quality of Life

    The change in quality of life as assessed by the standardised Rhinoconjunctivitis Quality of Life Questionnaire (RQLQ(s))

    Time frame: twice a year for 5 years

  4. Rhinitis Control

    change in symptom control of rhinitis assessed by Rhinitis Control Assessment Test (RCAT)

    Time frame: twice a year for 5 years

  5. Asthma Control

    The change of asthma control in asthmatic patients assessed by the (Childhood) Asthma Control Test (C-ACT/ACT)

    Time frame: twice a year for 5 years

  6. Incidence of Treatment-Emergent Adverse Events (safety and tolerability)

    frequency and severity of Treatment-Emergent adverse events

    Time frame: all year for 3 years

  7. treatment satisfaction

    directly assessed by the physician (questionnaire)

    Time frame: once after 3 years and once after 5 years
