Clinical trial developed at various hospitals where each patient randomly receive in parallel groups either placebo or treatment. Nor patients or investigators will know what the patient it's being given. This clinical trial evaluates efficacy and safety of the immunotherapy with allergen “Cup a 1” (major protein in Cupressus arizónica) in patients with allergic rhinoconjunctivitis with or without asthma sensitized to Cupressaceae pollen

Multicenter, double-blind, randomized, placebo-controlled phase III clinical trial in parallel groups which evaluates the clinical efficacy and safety of immunotherapy with the purified major allergen Cup a 1, in patients with moderate/severe allergic rhino conjunctivitis with or without controlled asthma, sensitized to Cupressaceae

Design outcomes

Primary

MeasureTime frame
Main Objective: Assessment of efficacy of specific immunotherapy with the purified and isolated protein Cup a 1 administered subcutaneously in patients sensitized to the allergen under study.;Secondary Objective: • Analysis of additional efficacy parameters to the combined index of symptom frequency and severity score together with rescue medication consumption score. • Evaluate the variation of follow-up skin tests with Cupressaceae and Cup a 1 extracts. • Control of asthma and allergic rhinitis assessment, using the ACT and the modified ARIA scale. • Patient's health status assessment using the VAS scale. • Quality of life evaluation according to rhinitis (ESPRINT-15). • Evaluate the immunological markers related to efficacy: IL-10, IL-13, INF-?, IgG4, total IgE and specific IgE against Cupressus arizonica and Cup a 1. • Evaluate the degree of tolerance against conjunctival provocation with Cupressaceae extract. • Evaluation of the safety of the treatment, through the registry of AA and AAG.;Primary end point(s): The efficacy of the treatment will be evaluated based on the symptom frequency and severity score together with the Combined Symptom and Medication Score (CSMS), which will be obtained through a questionnaire completed by the patient during 2 pollen seasons.;Timepoint(s) of evaluation of this end point: Visits V8, V9, V10, V20, V21 and V22 matching visits with January, February and march 2023 and 2024 (polinic season)
