Design outcomes

Primary

MeasureTime frame
Main Objective: The primary objective of this clinical trial in patients suffering from hay fever is the assessment of the safety and clinical tolerability of increasing doses of gpASIT+TM when administered by subcutaneous injections, in order to determine the maximal tolerated dose.;Secondary Objective: The secondary objectives of this trial are the assessment of the immunogenicity of increasing doses of gpASIT+TM administered subcutaneously and the comparison of the reaction to Conjunctival Provocation Test (CPT) performed before and after treatment as well as at Visit V5 ;Primary end point(s): The possible adverse reactions will be investigated by the systematic recording at predetermined time points of - general physical status, vital signs - solicited local adverse events, unsolicited adverse events, serious adverse events - haematological parameters - routine blood chemistry parameters - immunological analysis - inflammatory parameters - urinanalysis;Timepoint(s) of evaluation of this end point: - general physical status, vital signs (visit 1 to 8) - solicited local adverse events, unsolicited adverse events, serious adverse events (visit 2 to 8) - haematological parameters (visit 1 and 8) - routine blood chemistry parameters (visit 1 and 8) - immunological analysis (visit 1 and 8) - inflammatory parameters (visit 1 and 8) - urinanalysis (visit 1 and 8)

Secondary

MeasureTime frame
Timepoint(s) of evaluation of this end point: Theses will be performed before and after treatment as well as at visit 6;Secondary end point(s): The secondary objectives of this trial are the assessment of the immunogenicity of increasing doses of gpASIT+TM administered subcutaneously and the comparison of the reaction to Conjunctival Provocation Test (CPT)
