NCT00973453

Brief Summary

The aim of the study is to establish the maximum tolerated dose of PURETHAL Mites that is achieved by 90% of the patients with less than 20% of the injections giving rise to a swelling of \> 5 cm and the optimal regimen to reach this maximum dose will be determined.

Outcome Measures

Primary Outcomes (1)

  • Early Local Reactions (ELR) occurring 15 minutes after injection. Less than 20% of the injections should give rise to swelling at the injection site of > 5 cm in diameter occurring 15 minutes after injection.

    17, 14 or 11 weeks per patient for the respective groups

Secondary Outcomes (5)

  • Late Local Reactions (LLR) occurring within 24 hours after injection, and systemic reactions (SR). General adverse events will be recorded during complete study period.

    17, 14 or 11 weeks per patient for the respective groups

  • Clinical index score (CIS) during the study compared to baseline score (before treatment).

    weekly during per patient treatment periods of 17, 14 or 11 weeks for the respective groups

  • Conjunctival provocation test one week after reaching 10,000 AUeq, 20,000 AUeq, or 40,000 AUeq for the respective groups compared to baseline.

    after 7 weeks of treatment

  • Conjunctival provocation test 2 weeks after the patients have received two maintenance dosages compared to baseline score.

    17, 14 or 11 weeks for the respective treatment groups

  • Specific IgE and IgG measured 2 weeks after the patients have received two maintenance dosages compared to baseline score.

    17, 14 or 11 weeks for the respective treatment groups
