Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

A Randomized, Double-Blinded, Placebo-Controlled, Prospective, Multicenter Clinical Trial to Evaluate the Efficacy and Safety of Subcutaneous Immunotherapy in Patients With Rhinitis/Rhinoconjunctivitis With or Without Mild to Moderate Asthma Sensitized to cupressaceae and grasses.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The multicenter study includes 180 subjects sensitised to cupressaceae and grass pollen, both male and female aged 12 to 65 years.

The double-blinded and placebo controlled treatment will last 18 months for each subject.

The primary endpoint of the trial will be the combined rhinitis/rhinoconjunctivitis symptom and medication score (RCSMS) which will be assessed using data collected in the Subject electronic Diary during the cupressaceae (January, February and March) and grass (May and June) pollen seasons.

Participants Caregivers Investigators Outcome Assessors
During the trial, both the investigator and the included subjects will be unaware of the treatment each subject is receiving.

The person in charge of data analysis will also not know the treatment assigned to each subject until the database has been closed.

So that neither the subject nor the investigator knows what treatment each subject is receiving, all the trial medication is identical in terms of outer packaging and appearance.

4. Subjects with a positive skin prick-test (wheal size \>5 mm diameter) 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 molecular components of the mixture and to a cupressaceae extract. In addition, the largest diameter of the papules must be greater than or equal to that of the histamine.
5. Specific IgE \> 3,5 KU/L , against grass (preferably Phleum pratense) and cupressaceae pollen (InmunoCAP® o Immulite).
6. Women of childbearing age (from menarche) must present a urine pregnancy test with a negative result at the time of joining the trial.
7. Women of childbearing potential participating in the trial, should commit to using an appropriate method of contraception.

8. 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.

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.
