E.5 End points |
E.5.1 | Primary end point(s) |
The aim of the trial is to obtain information about the safety and tolerability of an accelerated dose escalation schedule with one strength for allergen immunotherapy with Allergovit® 6-Grasses.
The following descriptive safety variables will be considered:
• Number, incidence, time of onset, type and intensity of AEs and serious adverse events (SAE) according to MedDRA primary system organ class (SOC) and preferred term
• Number, incidence, time of onset, type and intensity of AEs and serious adverse events assessed as drug related (by investigator) according to MedDRA primary system organ class (SOC) and preferred term
• Incidence and intensity of allergic systemic reactions after injections according to the World Allergy Organization (WAO) grading system (see Section 18.4)
• Number of patients reaching the maintenance dose without dose adjustment due to adverse events
• Change of laboratory values (hematology, clinical chemistry and urinalysis) measured before and after the treatment phase
• Change of vital signs and lung function measured before and after the treatment phase
• Assessment of the overall tolerability by the investigator and the patient using a 5 point Likert scale (Likert, 1932) |
