Study & Design

Study Type: Interventional clinical trial of medicinal product

Study Design: Not specified

Primary Outcome Measures

Name	Time	Method
Main Objective: To assess the tolerability of the up-dosing phase of AVANZ® Salsola kali. The frequency of patients with investigational medicinal product (IMP)-related adverse events (AEs) will be the primary endpoint.;Secondary Objective: Frequency of patients with systemic reactions according to EAACI classification for the investigational medicinal procuct. <br>Increase in IgG4 and IgE for Salsola kali <br>Reduction in immediate skin reactivity for Salsola kali;Primary end point(s): Incidence of adverse reactions to Salsola kali AVANZ® immunotherapy.;Timepoint(s) of evaluation of this end point: After up-dosing phase and one maintenance dose (6 weeks)

Secondary Outcome Measures

Name	Time	Method
Secondary end point(s): Difference in Salsola kali IgE and IgG4 levels from baseline to end of trial. Changes in immediate skin response to Salsola allergens from baseline to end of trial by parallel line assay.;Timepoint(s) of evaluation of this end point: After up-dosing phase and one maintenance dose (6 weeks)
