Trial Outcomes & Findings for Subcutaneous Immunotherapy in Patients Sensitized to Dermatophagoides Pteronyssinus (DPT) (NCT NCT01489020)

NCT ID: NCT01489020

Last Updated: 2019-05-06

Results Overview

The primary end points were the number of ARs and the severity of local and systemic ARs (SARs) to SCIT administration. Proportions were compared between study arms. The tolerability of SCIT was evaluated by early and late local reactions (i.e., local swelling and redness) and systemic reactions after each injection (any symptoms from organs distant from the location of the injection). Reactions were classified depending on the severity and onset of the reaction, according to the EAACI classification (Alvarez-Cuesta 2006).
