NCT01438463

Brief Summary

The objective of the present study is to characterize the dose-response relationship of PURETHAL® Mites with a nasal provocation test in order to support the optimal dose in terms of clinical efficacy and safety. For this purpose 5 groups of 50 patients, suffering from rhinitis or rhinoconjunctivitis due to House Dust Mite Allergy will be treated during 1 year. Before start, after 6 months of treatment and at the end of the study patients will be subjected to a nasal provocation test.

Interventions

PlaceboBIOLOGICAL

Increasing volumes of placebo, will be administered by subcutaneous injection (starting with 0.05 ml) at weekly intervals till the maintenance dose (0.5 ml) is reached. Subsequently, maintenance dosages, corresponding to 0.5 ml of placebo, are given at 4-weekly intervals.
