General information about the trial
|
|||
Main objective of the trial |
The aim was to investigate if the combination of initial IgE-specific immunoadsorption and subsequent therapy with Omalizumab would increase the clinical threshold to the culprit food and thus prevent medical emergencies in patients with food anaphylaxis.
|
||
Protection of trial subjects |
All procedures performed in the study were standard procedures. No specific measures were needed to protect trial subjects.

Recruitment details |
Trial subjects were recruited from patients followed in The Allergy Centre, Odense University Hospital, Odense, Denmark. Recruitment period: 01-JUN-2018 - 22-FEB-2020. | ||||||||||||||||||||
Pre-assignment
|
|||||||||||||||||||||
Screening details |
Inclusion criteria were: 1) Age 18-70 years, 2) Verified food allergy with a specific IgE to the major allergen component of the culprit food of at least 10 kIU/l. All patients screened (n=10) were eligible and participated in the study. | ||||||||||||||||||||

End point title |
Fractional change in threshold (food challenge) between Tr0 and TrX (TrX/Tr0) [1] | ||||||||
End point description |
|||||||||
End point type |
Primary
|
||||||||
End point timeframe |
The threshold at food challenges (in milligrams) before any treatment (Tr0) was compared with threshold after the combined treatment with IgE apheresis and Omalizumab treatment (TrX). Change in threshold was expressed as a fraction/delta (TrX/Tr0)
|
||||||||
Notes [1] - No statistical analyses have been specified for this primary end point. It is expected there is at least one statistical analysis for each primary end point. Justification: This study was designed with no planned statistical analyses to be performed for any endpoints due to the simple design and small number of participants |
