Study summary

The objective of this trial is to assess the clinical efficacy of the modified extract (depigmented and polymerized with glutaraldehyde) of the subcutaneous injection of Parietaria Judaica pollen in the treatment of patients affected by allergic rhinitis/rhinoconjunctivitis ( with or without episodic asthma) induced by hypersensitivity to grass pollen, evaluating the score regarding symptoms and consumption of the medication.

Read the detailed description

Immunotherapy is a specific treatment for allergic diseases. Unlike conventional pharmacological treatment, immunotherapy is the only treatment that could modify the natural course of allergic disease. This is a prospective double-blind placebo controlled study with two arms of treatment: placebo and active.
