E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
1.To evaluate the efficacy of Omalizumab on food allergy thresholds in children.
|
1. At undersøge hvor meget behandling med lægemidlet Omalizumab (Xolair) vil øge den kliniske tærskelværdi for en ikke-tålt fødevare hos patienter med fødevareudløst anafylaksi
|
|
E.2.2 | Secondary objectives of the trial |
2.To evaluate if skin prick test (SPT), specific IgE (s-IgE), total-IgE (t-IgE), Histamine release (HR) test, Basophil Activation Test (BAT) and specific IgG4 to culprit foods can be used as predictors for the effect of Omalizumab.
3.To evaluate the efficacy of Omalizumab on comorbidity severity and Quality of Life (QoL).
|
2. At undersøge om ændringer i patientens allergiblodprøveværdier og hudpriktest kan anvendes til at forudsige effekten af Omalizumab
3. At undersøge effekten af behandling med Omalizumab på patientens øvrige allergisk sygdommeog på livskvalitet (QoL)
|
|
E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
100 children between 6 and 18 years with a clinical diagnosis of food allergy to ≥1 food allergen, including a positive skin prick test (SPT) (mean wheal diameter > 3mm), specific IgE (s-IgE) > 0.35 kIU/l to the allergen in question, and a positive food challenge with a threshold at or below 300 mg of protein (443 mg cumulative) in a double blind placebo controlled food challenge (DBPCFC) (Table 2). If the patient is allergic to more than one food allergen, the allergen with the highest probability of fulfilling the inclusion criteria (based on case history, level of specific IgE and when available challenge results within the last year) will be used. |
•100 patienter mellem 6 og 18 år
•have allergi overfor mindst en fødevare fx æg, mælk, sesam, torsk, rejer, peanut, hasselnød og/eller hvede, diagnosticeret ved en hudpriktest (nældefeberknop med diameter > 3mm), en positiv fødevareprovokation med en tærskelværdi, der er under eller lig med 300 mg protein (443 mg kumulativ) og en blodprøvemåling på specifik IgE > 0.35 kIU/l. Hvis patienten har fødevareallergi overfor flere end en fødevare testes på den fødevare, hvor patienten har lavest tærskelværdi
•må ikke indtage fødevaren, der ikke tåles under forsøget
•bære en adrenalin-pen på sig hele tiden under forsøget og kunne anvende den
|
|
E.4 | Principal exclusion criteria |
•Total IgE >1500 kU/L
•Significant co-morbidity that might compromise the patient’s safety or study outcomes
•Pregnancy or nursing in the adolescents. Women of childbearing potential have to use safe contraception (intrauterine device or hormonal contraception if sexual active). Safe contraception has to be used during the whole trial period and half a year after the last dose of the trial medicine has been taken.
•Ongoing treatment with antihistamine or drugs with antihistaminic effect
•Ongoing treatment with β-blockers and ACE-inhibitors
•Ongoing treatment with oral glucocorticoids/Omalizumab/allergen immunotherapy (AIT)
•Alcohol abuse, abuse of opioids or other drugs in adolescents
•Patients/parents who are not supposed to be able to meet the requirements in the protocol
•Patients/parents who are physically or mentally unable to consent
•Occurrence of unexpected side effects
•Patients who have reduced liver function or kidney function
|
•totalt IgE >1500 kU/L
•anden sygdom, der kan påvirke patientens helbred og sikkerhed eller forsøgsresultaterne
•gravid eller ammende. Kvinder i den fødedygtige alder og er seksuelt aktiv skal anvende sikker prævention (homonel kontraception (p-piller) eller intrauterine device (spiral)). Sikker prævention skal anvendes under hele forsøgsperioden og i ½ år efter sidste dosis forsøgsmedicin er taget
•formodes ikke at være i stand til at leve op til protokollen (problemer med fremmøde til planlagte besøg)
•vanlig brug af ß-blokkere eller ACE-hæmmere
•vanlig brug af glycokortikoid tabletter
•vanlig brug af antihistaminer eller andre lægemidler med antihistamininerg effekt fx visse typer psykofamaka
•har et misbrug af alkohol eller medicin/narkotika
•har nedsat lever- eller nyrefunktion
•forekomst af uventede bivirkninger•af fysiske eller psykiske årsager ikke er i stand til at overholde kravene i denne deltagerinformation

E.5 End points |
E.5.1 | Primary end point(s) |
Primary endpoint
Change in challenge threshold after 3 months of treatment in patients treated with Omalizumab versus placebo.
|
Patienter, der har modtaget behandling med lægemidlet Xolair, forventes at have højere tærskelværdi over indtagelse af den ikke-tålte fødevare |
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
Not applicable |
Ikke relevant |
|
E.5.2 | Secondary end point(s) |
Secondary endpoints
Change in challenge threshold, SPT, specific IgE, IgG4, HR test, BAT, severity of comorbidity, and quality of life at 3 and 6 months and from 0 to 6 months of treatment within and between the groups.
Our hypothesis is that increased Omalizumab dose and/or a longer treatment period will increase food allergy threshold.
Within the groups:
•3 months treatment with Omalizumab in asthma dose versus 6 months with Omalizumab in asthma dose – in primary responders
•3 months treatment with Omalizumab in asthma dosing versus 3 months additional treatment with Omalizumab in max dose – in primary non-responders
•3 months treatment with placebo versus 6 months with placebo – in primary placebo-responders
•3 months treatment with placebo versus 3 months with max dose Omalizumab – placebo cross over to active
Between the groups:
•3 months treatment with Omalizumab in asthma dose versus 3 months with max dose Omalizumab
•6 months treatment with Omalizumab in asthma dose versus 3 months with max dose Omalizumab
|
Fødevareallergiske patienter og deres pårørende forventes at skulle være mindre bekymrede for, at de fejlagtigt indtager fødevarer med spor af den fødevare, som vedkommende ikke kan tåle og dermed opnå en betydelig forøget livskvalitet. |
