Intervention(s):

1. Group A (experimental): VALERGEN-DP + VALERGEN-BT by sublingual route. The treatment has 2 phases: Increasing phase: Vaccination daily for 23 days and a maintenance phase: Vaccination twice a week (Monday and Friday) until 12 months. Increasing phase: Day 1 to 7: concentration of 10 UB/mL VALERGEN-DP and 10 BU / mL VALERGEN-BT. Day 8 to 14: concentration of 100 UB/mL VALERGEN-DP and 100 BU/mL VALERGEN-BT. Day 15 to 21: concentration of 1000 UB/mL VALERGEN-DP and 1000 BU/mL VALERGEN-BT. Day 22 and 23: concentration of 10000 UB/mL VALERGEN-DP and 10000 BU/mL VALERGEN BT Maintenance phase: It starts when the patient reaches the maximum tolerated dose (recommended between 600 and 2000 UB/mL). The maximum tolerated dose is “the dose at which no systemic reactions were observed grade I-IV”. For patients receiving complete the increasing phase, the maintenance dose is 2000 UB. 2. Group B (Control): VALERGEN-BT + placebo by sublingual route.

Day 15 to 21: concentration of 1000 UB/mL VALERGEN-BT and Placebo. Day 22 and 23: concentration of 10000 UB/mL VALERGEN-BT and Placebo Maintenance phase: It starts when the patient reaches the maximum tolerated dose (recommended between 600 and 2000 UB/mL). The maximum tolerated dose is “the dose at which no systemic reactions were observed grade I-IV”. For patients receiving complete the increasing phase, the maintenance dose is 1000 UB. 3.

Outcomes and Timepoint

Section to complete information about primary and secondary outcomes including. It includes the metric or method of measurement used and, the time point for every outcome.

Primary outcome(s):

1. Symptom score (Dyspnea, cough, expectoration, wheeze and chest tightness using a four-digits score: 0= non symptom, 1=mild, 2 = moderate, 3 = severe). Measurement time: daily, pre-treatment and during 12 months. 2. Consumption of medications (three-digit score: 0= no use, 1= use beta-2 agonists, metilxantine, ephedrine, adrenaline, 2 = corticosteroids). Measurement time: daily, pre-treatment and during 12 months. 3. Determination of Peak Expiratory Flow-PEF (using standard meter of PEF: FERRARIS POCKETPEAK). Measurement time: twice daily, pre-treatment and during 12 months. 4. Skin reactivity: (value Ch10: relative allergen concentration causing in the patient a similar wheal to induced wheal by a HCL histamine solution (10 mg/mL= 54.3 mmol/L de Histamina base)). Measurement time: pre-treatment, 6 and 12 months. 5. Quality of life (according to AQLQ(S) Asthma Quality of Life Questionnaire: seven-digit score (1 = maxim deteriorate to 7= no deteriorate)). Measurement time: pre-treatment, 6 and 12 months.

Key secondary outcomes:

1. Respiratory function classification (Criterion according PEF and PEF Variability: normal, mild obstruction, moderate obstruction, severe obstruction). Measurement time: pre-treatment, 6 y 12 months. 2. General evaluation (based on symptom-medication score, respiratory function, skin reactivity, quality of life: Better, Equal, Worse). Measurement time: pre-treatment, 6 y 12 months. 3. Allergen-specific antibodies (Measuring serum allergen-specific antibodies IgG4 and IgE level in the patients using indirect ELISA). Measurement time: pre-treatment, 6 and 12 months. 4. Adverse events-AE (Occurrence of some AE (Yes, No), Description of the AE (Name of adverse event),According to available previous information (Unexpected, Expected), According to its localization the expected AE (World Allergy Organization Criterion: local and systemic AE (0= Nonspecific Symptoms, I= Mild systemic reactions, II= Moderate systemic reactions, III= Severe (nonlife-threatening) systemic reactions, IV= Anaphylactic shock)), Duration of the AE (Time between the start and the end of the AE), Graveness of the AE (Serious, No serious), Attitude regarding the treatment in study (Without changes, Dose modification, Temporary interruption, Definitive interruption), Result of the AE (Recovered, Improved, Persists, Sequels), Causality Relationship of the AE (1.Very likely, 2.Likely, 3.Possible, 4.Unlikely, 5.Not related, 6.Not evaluated)). Measurement time: weekly during the first month and, monthly until month 12.
