About this trial

This is an interventional screening trial for Rhinitis focused on measuring Rhinitis / Rhinoconjunctivitis, Vaccine, Immunotherapy, Grass pollen, Allergy

Eligibility Criteria

14 Years - 65 Years (Child, Adult, Older Adult)All SexesDoes not accept healthy volunteers

Inclusion Criteria:

  • Written informed consent
  • Positive suggestive clinical history of intermittent or persistent moderate to severe rhinitis /rhinoconjunctivitis, with or without moderate asthma, due to grass pollen allergy
  • Subjects with a positive skin prick-test (wheal sixe >6 mm diameter) Specific immunoglobulin E (IgE, CAP >3) to grass pollen
  • Age between 14 and 65 years
  • Both genders
  • Subjects capable of giving informed consent
  • Subjects capable of complying with the dosing regimen
  • Subjects that have not received immunotherapy in the last 5 years
  • Subjects presenting sensitization to another aeroallergens and or mites, cats or dogs, but that is considered clinically not relevant or no clinical interference with the nasal provocation test.

Exclusion Criteria:

  • Subjects outside of the age range.
  • Subjects who have previously received immunotherapy for the treatment of the allergic rhinitis/rhinoconjunctivitis due to grass pollen and other allergens in the last 5 years.
  • Subjects that immunotherapy may be an absolute contraindication according to the criteria of the immunotherapy Committee of the Spanish society of Allergy and Clinical Immunology, and of the European Allergy and Clinical Immunology Immunotherapy Subcommittee may also include.
  • Subjects with important symptoms of rhinoconjunctivitis /bronchial asthma in which the suspension of the systemic antihistamine treatment is contraindicated.
  • Subjects with persistent severe or not controlled asthma , with a forced expiratory volume (FEV) < 70 respect to the reference value in spite of the appropriate pharmacological treatment at the time of the inclusion in the trial.
  • Subjects that have required oral corticosteroids in the 12 weeks previous to the inclusion in the trial.
  • Subjects that have previously submitted a serious secondary reaction during the skin prick test
  • Subjects in treatment with beta blockers.
  • Unstable subjects from the clinical point of view (respiratory infection, febrile, acute urticaria, etc.) at the time of the inclusion in the clinical trial
  • Subject with chronic urticaria in the last 2 years or hereditary angioedema.
  • Subjects that have some pathology (hyperthyroidism, hypertension, heart disease, etc.) is contraindicated.
  • Subjects with any other disease not associated with the rhinitis/rhinoconjunctivitis, but of potential severity and that could interfere with treatment and follow-up (epilepsy, psychomotor deterioration, diabetes, malformations, multi-operated, kidney diseases,...).
  • Subjects with autoimmune disease (lupus, thyroiditis, etc.), tumor or with diagnosis of immunodeficiency diseases.
  • Subject whose status prevents him from providing cooperation and or which present severe psychiatric disorders.
  • Subject with known allergy to other components of the vaccine different from pollen of grasses.
  • Subjects with lower airway diseases other than asthma such as emphysema or bronchiectasis.
  • Direct investigator's relatives.
  • Pregnant or women at risk of pregnancy and breastfeeding women.

Outcomes

Primary Outcome Measures

Concentration required to elicit a positive response after nasal provocation test (NPT)
Change in the threshold concentration of grass allergen extract, measured in Histamine Equivalent Prick per ml (HEP/ml), needed to trigger a positive response after nasal provocation test (NPT) assessed by acoustic rhinometry. This will be compared between the beginning and end of the trial and among active groups and placebo.

Secondary Outcome Measures

Dose finding skin prick test
Comparison between the beginning and end of the trial and among active groups and placebo
Cytokine production by T cells specific allergen
Comparison between the beginning and end of the trial and among active groups and placebo
Immunoglobulin production by B cells specific allergen
Comparison between the beginning and end of the trial and among active groups and placebo
Phenotypic and functional analysis of dendritic cells
Will be analyzed changes in the frequency of plasmacytoid dendritic cells, myeloid dendritic cell and Treg cells in peripheral blood, between the beginning and end of the trial and among active groups and placebo The frequencies of peripheral blood mononuclear cells in each of the above populations is determined before and after treatment with mannosylated polymers by flow cytometry after staining with specific antibodies.
Number of participants with treatment-related adverse events as assessed by MG56-SIT-012
Comparison between the beginning and end of the trial and among active groups and placebo
