Sublingual route: Treatment has 2 phases: Increasing phase administration daily for 23 days and maintenance phase (twice for week, Monday a Friday) until 12 months. Increasing phase: Day 1 to 7: Concentration of 20 UB/mL. Day 8 to 14: Concentration of 200 UB/mL. Day 15 to 21: Concentration of 2000 UB/mL. Day 22 to 23: Concentration of 20000 UB/mL. 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 grade I-IV. For patients receiving complete the increasing phase, the maintenance dose is 2000 UB. Subcutaneous route: Treatment has 2 phases: Increasing phase administration weekly for 13 weeks and maintenance phase every 4 weeks until 12 months. Increasing phase: Week 1 to 3: Concentration of 20 UB/mL. Week 4 to 6: Concentration of 200 UB/mL. Week 7 to 10. Concentration of 2000 UB/mL. Week 11 to 13: Concentration of 20000 UB/mL. Maintenance phase. It starts when the patient reaches the maximum tolerated dose (recommended between 800 and 6000 UB/mL). The maximum tolerated dose is the dose at which no are systemic reactions grade I-IV. For patients receiving complete the increasing phase, the maintenance dose is 6000 UB.

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. Frequency of asthma attacks (Occurrence of crises in the past 14 days. Is calculated by dividing the number of days with crisis from 14-range between 0 and 1). Measuring time: at baseline, 6 and 12 months. 2. Severity of asthma attacks (Considering where the patient resolved the crisis in the last 14 days where 0: not present crisis and these were resolved at home, 1: all crises were resolved at home, but was required broncodilatadore, 2 use: at least one crisis required the use of inhaled corticosteroids and / or oral at home or required home care in emergency, 3: hospitalization is required). Measuring time: at baseline, 6 and 12 months. 3. Consumption of medications Keeping in mind the consumption of medications in the last 14 days (0= no use, 1= use beta-2 agonists, metilxantine, ephedrine, adrenaline, 2 = inhaled corticosteroids, 3= oral and injected corticosteroids). Measuring time: at baseline, 6 and 12 months. 4. Quality of life (according to Asthma-Junniper Quality of Life Questionnaire AQLQ(S): seven-digit score (1 = maxim deteriorate to 7= no deteriorate)). Measuring time: at baseline, 6 and 12 months. 5. Adverse events-AE (- Occurrence of some AE in the patient (yes/no). - Description of the AE (Name of adverse event). - According to available previous information (unexpected and 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 (Difference of dates between beginning and termination of event) - Intensity of the AE (Light, Moderate, Severe) - Graveness of the AE (Serious, No Serious) - Attitude regarding the treatment in study (without changes, dose modification, temporary or definitive interruption of the treatment in study) - Result of the AE (recovered, improved, it persists or sequels) - Causality Relationship of the AE (1.Very Likely, 2.Likely, 3.Possible, 4.Non-Improbable, 5.No related, 6.No evaluable). Measuring time: weekly in the first months, monthly from months 2 until months 12.

Key secondary outcomes:

General Criteria for Improvement (Based on the score of frequency and severity of asthma attacks, and drug use, quality of life index: better, same or worse). Measuring time: 6 and 12 months.
