NameTimeMethod
Main Objective: Establish a dose-response relationship for the treatment of rhinitis/rhinoconjunctivitis due to mites allergy treatment sublingual therapy.;Secondary Objective: As secondary objectives will be assessed the efficacy, tolerance and safety of four concentrations for both immunotherapy subcutaneous and sublingual immunotherapy.<br>The influence of treatment on the following parameters were also assessed:<br>- Dose response skin prick test<br>-Evolution of symptoms<br>- Medication consumption<br>- Quality of life;Primary end point(s): Change of the threshold concentration necessary to cause a reaction positive after the test of nasal provocation (TPN) between the start and the end of the trial, by acoustic rhinometry.;Timepoint(s) of evaluation of this end point: Begining and end of the clinical trial
