Outcome Measures

Primary Outcomes (1)

  • Conjunctival Provocation Test (CPT) With House Dust Mite Allergen Solutions. Change of Median Individual Allergen Tolerance Compared to Baseline (Factor of Increase in Allergen Concentration to Induce a Threshold CPT Score ≥ 2)

    The outcome measure is a conjunctival provocation test (CPT) with house dust mite allergen solutions. CPT score was measured as a sum of the following assessed symptoms: conjunctival hyperemia, tearing, itching, burning and swelling of eyelids. Each of the assessed symptom could be absent (0), mild (1 point), moderate (2 points) or severe (3 points). The provocation tests started with the maximal dilution of the allergen 1:1000. If the sum of the reached CPT score was \<10 points, the test continued with the next dilution step 1:100. This procedure was repeated until patients reached the CPT score ≥ 10 points or the provocation solution reached the maximal concentration 1:1 (undiluted). The outcome is then given as the change of median individual allergen tolerance at month two compared to baseline. The change is expressed as a factor of increase in allergen concentration to induce a threshold CPT score ≥ 2.

Eligibility Criteria

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

You may qualify if:

  • Mild to moderate perennial allergic rhinoconjunctivitis due to hypersensitization towards house dust mite allergens

You may not qualify if:

  • Clinically relevant other allergies (perennial or seasonal) that could potentially interfere with the patient's study treatment schedule or assessments
  • Use of any concomitant medication that could affect the patient's study treatment response or assessment results
