Brief summary
The purpose of this trial is to investigate if treatment with house dust mite allergen immunotherapy tablet can reduce the risk of asthma exacerbation in subjects with house dust mite induced asthma.
Interventions

Oral lyophilisate, 6 DU, to be administered sublingually once daily for 14-18 months.
Oral lyophilisate, 12 DU, to be administered sublingually once daily for 14-18 months.
