Eligibility Inclusion Criteria: 1. Subjects who have signed the informed consent 2. Subjects with a confirmed medical history of asthma (intermittent or persistent mild-moderate, controlled), as defined by GEMA 5 with moderate-severe rhinitis / rhinoconjunctivitis (intermittent or persistent) according to the ARIA classification caused by polysensitization to grass pollen and mites (D. pteronyssinus and / or D. farinae). The diagnosis of asthma will be valid from 24 months prior to signing the informed consent. 3. Subjects with a positive prick test (major diameter of the papule = to 5 mm) to a standardized extract of grass pollen mixture, or to one of the components of the mixture (Dactilys glomerata, Poa pratensis, Holcus lanatus, Festuca elatior, Phleum pratense and Lolium perenne) and to an extract of D. pteronyssinus and / or D. farinae. Results will be valid 12 months prior to signing the informed consent. 4. Specific IgE (CAP or Immulite) against one of the components of the mixture of grasses, preferably Phleum pratense or a mixture of grasses and mites (D. pteronyssinus and / or D. farinae) or one or more of the molecular components of allergenic sources with a value > 3,5 KU / L. Results will be valid 12 months prior to signing the informed consent. 5. Subjects will preferably be sensitive to study allergens (Dermatophagoides and grasses). In the case of subjects sensitized to other aeroallergens, only those with the following characteristics (results valid up to 12 months prior to signing of the informed consent) can be included in the study: 1. Subjects with a positive prick test for Blomia tropicalis and Lepidoglyphus destructor, whose maximum values of specific IgE are 3.5 KU/L and do not exceed or equal the values of the allergens of the study (Dermatophagoides and grasses). 2. Subjects with a negative prick test to epithelium, whose specific IgE values are < 0.35 KU/L. Subjects with occasional exposure and symptomatology to epithelium may be included with a positive prick test regardless of the value of the specific IgE. 3. Subjects with a positive prick test for non-coestational pollens, whose maximum values of specific IgE are 17.5 KU / L and do not exceed or equal the values of the allergens of the study (Dermathophagoids and grasses) and who also do not present exacerbations in the pollen season. 6. Subjects with a negative prick test for fungi. If the specific IgE determination has been made, the result shall be < 0,35 KU/L. 7. Subjects with a negative prick test for coestacional pollens with grasses. If the specific IgE determination has been made, the result shall be < 0,35 KU/L. 8. Subjects aged between 12 and 65 years, inclusive. 9. Subjects capable of complying with the dosing regimen. 10. Women of childbearing age (from menarche) should submit a urine pregnancy test with a negative result at the time of enrolment in the trial. 11.

Outcome

Type Measure Description Time frame Safety issue
Primary CSMS: Combined Symptoms and Medication Score Evaluation of the number of symptoms and the consumption of medication necessary for the control of such symptoms in asthma and rhinitis / rhinoconjunctivitis of each subject during the trial, of the groups with each other and with respect to placebo.
- The endpoint for each asthma and rhinitis / rhinoconjunctivitis symptom will be as follows: 0 = No symptoms; 1 = Mild; 2 = Moderate; 3 = Severe
Total daily symptom score = 0-3
The asthma medication will be scored based on the therapeutic step in which drugs are included in the GEMA 5 guide.
The rhinitis / rhinoconjunctivitis medication score: 0 = No medication; 1 = oral or topical (eyes or nose) non-sedative H1 antihistamines (H1A); 2 = intranasal corticosteroids (INS) with / without H1A; 3 = oral corticosteroids with/without (INS), with/without H1A
Total daily medication score = 0-3
12 months
Secondary Medication-free days Number of days that the subjects need no medication 12 months
Secondary Symptom-free days Number of days that the subjects have no symptom 12 months
Secondary Respiratory function_FEV1 Measurement of Forced Expiratory Volume in 1 Second (FEV1) % 12 months
Secondary Respiratory function_PEF Peak Expiratory Flow (PEF) [velocity] 12 months
Secondary Asthmatic exacerbations Time elapsed until the first appearance of asthmatic exacerbations, number, duration and severity. 12 months
Secondary Immunological parameters Analyses of total and specific IgE, specific IgE index / total IgE and specific IgG4 12 months
Secondary Visual Analogue Scale (VAS) Visual Analogue Scale in which the subject has to indicate in a straight line of 10cm how he/she feels regarding to his allergy symptoms. Being left side (0) = very bad and right side (10) = very well 12 months
Secondary Quality of life associated with rhinitis The quality of life associated with rhinitis will be measured following the test ESPRINT-15.
The scoring of the questionnaire will be carried out as follows: The global sum of the scores (ranging from "0 = nothing has bothered me" to "6 = it has bothered me a lot") of the 14 items plus the score given in the general questionnaire (ranging from "0 = Excellent" to "4 = Bad"). This sum is divided by the total number of items (15 items).
The interpretation of the scores is between 0 (low impact) and 6 (high impact).
12 months
Secondary Quality of life associated with asthma The quality of life associated with asthma will be measured following the ACQ questionnaire.
The ACQ questionnaire consists of 7 questions (ACQ-7) or 6 questions (ACQ-6). In questions 1-6, patients recall their experience during the last 7 days and answer using a scale of 7 points (from 0 = fully controlled to 6 = extremely poorly controlled). The seventh question, which refers to the% FEV1 of the reference value, must be completed by an employee of the site. The questionnaire score is the mean of the 7 responses (ACQ-7) or 6 responses (ACQ-6).
The interpretation of the scores is as follows:
Less than or equal to 0.75: Adequate control of asthma
From 0.75 to 1.50: Partially controlled asthma
More than 1.50: Inadequate asthma control
12 months
Secondary Consumption of health resources For each patient, the number of times that due to allergy symptoms has done the following will be counted:
have visited the family doctor
have made an unscheduled visit to the specialist
has gone to the emergency room
has been hospitalized
have needed to contact the doctor by phone
12 months
Secondary Security parameters Global rate and severity of AE per administration and per subject 12 months
Secondary Number of Local Adverse Reactions Local adverse reactions are those that appear at the site of the administration. They are classified into: Inmediate (it appears during the first 30 minutes from the administration of investigational product) and Late (it appears after the first 30 minutes from the administration of investigational product)
Local adverse reactions are considered if a papule > 5 cm in diameter occurs in the first 30 minutes after administration (immediate local reactions) or > 10 cm if it is later (late local reactions).
12 months
Secondary Number of Systemic Adverse Reactions Systemic adverse reactions are those that appear in other parts of the body other than the site of administration.Their severity will be classified following the indications proposed by the World Allergy Organization (WAO) in 2010, measured according to the following grades:
Grade 0: Absence of symptoms or nonspecific symptoms.
Grade 1: Signs or symptoms present in a system / organ (cutaneous, Upper respiratory tract, Conjunctival or Other)
Grade 2: Signs and symptoms of 2 or more organs / systems listed in Grade 1, or; Lower airway disease, or; Gastrointestinal symptoms, or; Other
Grade 3: Lower airway disease, or; Upper airway involvement
Grade 4: Lower or upper airway condition, or; Cardiovascular system involvement
Grade 5: Death
12 months
Secondary Number of Adverse Reactions to any medication Number of Adverse Reactions to any medication administered for the treatment of AE 12 months
