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.

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
