The asthma diagnosis will be valid up to 24 months prior to signing the informed consent.
- Positive skin prick test (wheal major diameter ≥ 5 mm) to a standardized allergen extract of Dermatophagoides pteronyssinus and/or Dermatophagoides farinae.
- Specific IgE against a complete extract of D. pteronyssinus and/or D. farinae or any of the molecular components of allergenic sources with a value ≥ 3.5 kU/L.
- Women of childbearing age must have a urine pregnancy test negative result before enrolling the study.
- Women of childbearing age must commit to using an adequate contraception method.
- Capable of complying with dosage regimen.
- Owning a smartphone to register symptoms and medication consumption.
- A negative skin prick test to other aeroallergens with specific IgE < 3.5 kU/L with no clinical relevance.
Exclusion Criteria:
- Previous immunotherapy to any of the tested allergen during the last 5 years or any desensitization process in the last 2 years (ITO, milk, egg, ...) or currently receiving immunotherapy with any other allergen.
- Positive skin prick test to other aeroallergens, except for intermittent symptoms due to temporary exposition to dander.
- Those cases in which AIT would be a contraindication according to the criteria of European Allergy and Clinical Immunology Immunotherapy Subcommittee.
- Uncontrolled or severe asthma and/or FEV1 <70% despite pharmacological treatment by the time of enrolment.
- Intake of β-blockers.
- Use of immunosuppressive or biological drug.
- Unstable patients by the time of enrolment (acute exacerbation asthma, respiratory infection, fever, acute pruritus, etc).
- Patients who have suffered chronic urticaria during the last 2 years, severe anaphylaxis, or family history of angioedema.
- Having any contraindication for the use of adrenaline (hyperthyroidism, heart disease, high blood pressure).
- Other severe diseases not related to allergic asthma or rhinitis that could interfere in the study treatment or the follow-up (epilepsy, psychomotor agitation, diabetes, malformations, nephropathy) according to medical criteria.
- Autoimmune diseases (thyroiditis, lupus, etc.), tumoral diseases or immunodeficiencies.
- Participants that the investigator believes could not comply with the study protocol or have serious psychiatric disorders.
- Known allergy to any of the ingredients of the study medication except for mites.
- Lower respiratory tract diseases different from asthma as bronchiectasis or chronic obstructive pulmonary disease.
