Subjects capable of complying with the dosing regimen. 9. Subjects who own a smartphone for symptom registration and medication. 10. Subjects with a negative prick test to coestational pollens. In the case specific IgE is available, the result should be <3,5 kU/L and without relevant symptomatology 11. Subjects with a negative prick test to other aeroallergens (dust mites, epitheliums and fungus). In the case specific IgE is available, the result should be <3,5 kU/L and without relevant symptomatology. Exclusion Criteria: 1. Subjects with positive prick test to other aeroallergens except for sensitisation to epithelia with occasional exposure and symptoms. 2. Subjects with positive prick test to other aeroallergens except for sensitisation to pollen noncoseasonal with cupressus or grasses. 3. Subjects who have received prior immunotherapy in the preceding 5 years for any of the allergens tested or a cross-reactive allergen or are currently receiving immunotherapy with any allergen. 4. Subjects in which immunotherapy may be subject to an absolute general contraindication according to the criteria of the Immunotherapy Committee of the Spanish Society of Allergy and Clinical Immunology and the European Allergy and Clinical Immunology Immunotherapy Subcommittee. 5. Subjects with severe or uncontrolled intermittent or persistent asthma, with an FEV1 <70% with respect to the reference value despite adequate pharmacological treatment at the time of inclusion in the trial. Likewise, subjects with intermittent or persistent rhinitis / rhinoconjunctivitis with severe symptoms in which the suspension of oral or systemic antihistamine treatment is contraindicated. 6. Subjects who have previously had a severe secondary reaction during the prick test diagnostic skin test. 7. Subjects treated with beta-blockers. 8. Clinically unstable subjects at the time of inclusion in the trial (acute asthmatic exacerbation, respiratory infection, febrile process, acute urticaria, etc.). 9. Subjects with active chronic urticaria, severe dermographism, severe atopic dermatitis, sunburn, active psoriasis with lesions in areas where skin tests will be performed, or a history of hereditary angioedema. 10. Subjects who have any pathology in which adrenaline administration is contraindicated (hyperthyroidism, HTN, heart disease, etc.). 11. Subjects with any other disease not related to moderate rhinoconjunctivitis or asthma, but potentially serious and that may interfere with treatment and follow-up (epilepsy, psychomotor disorder, uncontrolled diabetes, malformations, multioperated patients, kidney disease,). 12. Subjects with autoimmune disease (thyroiditis, lupus, etc.), tumor diseases or with a diagnosis of immunodeficiencies. 13. Subject whose condition prevents from offering cooperation and/ or who has severe psychiatric disorders. 14. Subjects with a known allergy to components of the investigational medicinal product other than the allergen. 15. Subjects with lower respiratory diseases other than asthma such as emphysema or bronchiectasis. 16. Subjects who are direct relatives of the researchers. 17. Pregnant or lactating women. |

Type | Measure | Description | Time frame | Safety issue |
---|---|---|---|---|
Primary | CSMS: Combined Symptoms and Medication Score, asthma and rhinitis. | 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. | 12 months | |
Secondary | Medication free days | Both rhinitis/rhinoconjunctivitis and asthma | 12 months | |
Secondary | Symptom free days | Both rhinitis/rhinoconjunctivitis and asthma | 12 months | |
Secondary | Number of participants with treatment-related adverse events as assessed by T521+MG01-SIT026 | Comparison between the beginning and end of the trial and among active groups and placebo | 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 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 questionnaire score is the mean of the 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 | 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 | Asthmatic exacerbations | Time elapsed until the first appearance of asthmatic exacerbations, number, duration and severity. | 12 months | |
Secondary | Health resource consumption | Counting the Health resource consumption: visits to specialists, telephone calls, test and analyses. | 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). |
