简要总结
The main objective of this clinical trial is to evaluate the clinical efficacy of subcutaneously administered polymerized allergen extracts compared to placebo in subjects with rhinitis/rhinoconjunctivitis according to the ARIA classification, with or without controlled intermittent or persistent (mild-moderate) asthma, as defined by GEMA 5.0

入选标准
- •Subject who has signed the informed consent form.
- •Subjects with negative skin prick test for co-seasonal pollens. In case specific IgE determination has been performed, the result must be < 3.5 kU/L and without relevant clinical signs.
- •Subjects with negative skin prick test to other aeroallergens (mites, fungi, and dander). In case specific IgE determination has been performed, the result must be < 3.5 kU/L and without relevant clinical signs.
- •Subjects of both sexes aged between 12 and 65 years.
- •Subjects with a confirmed clinical history of inhalation 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 classification) caused by grass and olive tree allergy. The asthma diagnosis will be valid from 12 months prior to signing the informed consent.
- •Subjects with a positive skin prick test (wheal major diameter ≥ 5 mm) to a standardized mixed extract of grass pollen (Phleum pratense, Holcus lanatus, Dactylis glomerata, Poa pratensis, Festuca elatior, Lolium perenne), or to one of the components of the mixture and an olive tree extract.
- •Specific IgE (CAP or Immulite) to a grass mixture or to one of the components of the grass mixture, preferably to Phleum pratense and olive tree or to one of the molecular components of the allergenic sources with a value > 3.5 KU/L.
- •Women of childbearing age (from menarche) must present a urine pregnancy test with negative result at the time of entry into the trial.
- •Women of childbearing age participating in the trial must agree to use an appropriate method of contraception. Medically acceptable methods of contraception are intrauterine devices inserted at least 3 months in advance, surgical sterilisation (e.g., tubal ligation), barrier methods, or the use of oral contraceptives.
- •Subjects capable of complying with the dosing regimen.
- •Subjects owning a smartphone to record symptoms and medication.
排除标准
- •Subjects with positive skin prick test to other aeroallergens, except for dander with occasional exposure and symptomatology.
- •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 of potential severity and that may interfere with treatment and follow-up (epilepsy, psychomotor impairment, uncontrolled diabetes, malformations, multiple surgeries, nephropathy).
- •Subjects with autoimmune disease (thyroiditis, lupus, etc.), tumour diseases or diagnosed with immunodeficiencies.
- •Subject whose condition prevents him/her from offering cooperation and/or who has severe psychiatric disorders.
- •Subjects with known allergy to components of the investigational medicinal product other than the allergen.
- •Subjects with lower respiratory tract diseases different from asthma such as emphysema or bronchiectasis.
- •Subjects who are immediate family members of investigators.
- •Pregnant or breastfeeding women.
- •Subjects with positive skin prick test to other aeroallergens, except for non-co-seasonal pollens with grasses and olive tree.
- •Subjects who have received immunotherapy to pollens in the last 5 years or are currently receiving immunotherapy with any allergen.
- •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 persistent severe or uncontrolled asthma, with an FEV1 < 70% of baseline despite adequate pharmacological treatment at the time of inclusion in the trial. Also subjects with intermittent or persistent rhinitis/rhinoconjunctivitis with severe symptoms in whom discontinuation of oral or systemic antihistamine treatment is contraindicated.
- •Subjects who have previously presented a severe secondary reaction during diagnostic skin prick test.
- •Subjects on treatment with ß-blockers.
- •Clinically unstable subjects at the time of inclusion in the trial (acute asthma exacerbation, respiratory infection, febrile process, acute urticaria, etc.).
- •Subjects with chronic active urticaria, severe dermographism, severe atopic dermatitis, sunburn, active psoriasis with lesions in areas where skin prick test will be performed, or a history of hereditary angioedema.
