Clinical trial to assess the efficacy and safety of a vaccine for dust mite allergy
EU CTIS ID: 2024-514090-21-00
What this study is testing
The main objective of this trial is to evaluate the clinical efficacy of subcutaneously administered polymerised allergen extracts compared to placebo in subjects with moderate-severe intermittent or persistent rhinitis/rhinoconjunctivitis according to the ARIA classification with or without mild-moderate controlled intermittent or persistent asthma as defined by GEMA 5.0.
- Therapeutic confirmatory (Phase III)

- Subjects diagnosed with asthma according to GEMA 5.0.
- Subjects able to comply with the dosing regimen.

- Subjects with a confirmed clinical history of inhalant allergy (intermittent or persistent moderate-severe rhinitis and/or rhinoconjunctivitis according to the ARIA classification with or without controlled intermittent or persistent mild-moderate asthma according to the GEMA 5.0 definition) caused by allergy to Dermatophagoides pteronyssinus and/or Dermatophagoides farinae.
- Subjects who have had a prick test result ≥ 5 mm in diameter greater for Dermatophagoides pteronyssinus and/or for Dermatophagoides farinae. Positive and negative control test results must be consistent.
- Subjects with a specific IgE value > 3.5 KU/L (ImmunoCAP® or Immulite) for complete extract of Dermatophagoides pteronyssinus and/or for Dermatophagoides farinae or for some of the molecular components of these allergenic sources
- Subjects shall preferably be monosensitised to the study allergens. In the case of subjects sensitised to other aeroallergens, only those with the following characteristics (results valid 12 months prior to signing the informed consent) may be included in the study: (a) Subjects with positive skin test to Blomia tropicalis and Lepidoglyphus destructor, whose maximum specific IgE values are 3.5 KU/L. b) Subjects with negative skin test. Subjects with positive skin tests for epithelia may be included in the study, provided that they have occasional exposure and symptomatology. c) Subjects with positive skin tests for pollens, whose specific IgE values do not exceed or equal the values for the study allergens and who, in addition, do not present exacerbations in the pollen season. The maximum value of specific IgE for these allergens is 17.5 KU/L.
- Subjects with negative skin test for fungus.
- Women of childbearing age (since menarche) should submit a negative urine pregnancy test at the time of entry into the trial, prior to administration of the first dose of investigational medicinal product.
- Women of childbearing potential participating in the trial should agree to use an adequate method of contraception, defined as any act, device, or medication to prevent conception or a viable pregnancy, during the trial if sexually active.
What rules you out
- Subjects who have received previous immunotherapy in the previous 5 years to epithelia, fungi and mites.
- Subjects with autoimmune disease (thyroiditis, lupus, etc.), tumour diseases or diagnosed with immunodeficiencies.
- Subjects whose condition prevents them from cooperating or who present severe psychiatric disorders.
- Subjects with known allergy to components of the investigational medicinal product other than the allergen.
- Subjects with lower respiratory tract diseases other than asthma such as emphysema or bronchiectasis.
- Subjects who are immediate family relatives of researchers.
- Pregnant or breastfeeding women.
- Subjects in whom immunotherapy may be subject to 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.
- Subjects with severe or uncontrolled persistent asthma, with an FEV1 < 70% of baseline despite adequate pharmacological treatment at the time of inclusion in the trial.
- Subjects who have previously exhibited a severe secondary reaction during diagnostic skin prick tests.
- Subjects on ß-blocker treatment.
- Subjects who are clinically unstable at the time of inclusion in the trial (acute asthmatic exacerbation, respiratory infection, febrile process, acute urticaria, etc).
- Subjects with active chronic urticaria, severe dermographism, severe atopic dermatitis, sunburn, active psoriasis with lesions in areas where skin testing will be performed, or a history of hereditary angioedema.
- Subjects with any pathology in which the administration of adrenaline is contraindicated (hyperthyroidism, hypertension, heart disease, etc.).
- Subjects with any other disease not related to moderate rhinoconjunctivitis or asthma, but potentially serious and which may interfere with treatment and follow-up (epilepsy, psychomotor alteration, uncontrolled diabetes, malformations, multioperative, nephropathy, etc.).
