E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
It is to evaluate the long-term effectiveness either of SLIT or placebo in pediatric allergic asthma, i.e. the sparing effect of asthma-controller medications (either inhaled or oral CS, long-acting bronchodilators, and leukotriene modifiers) and asthma-relievers (rapid-acting bronchodilators) over 24 months. |
Obiettivo principale: Valutare l’efficacia a 2 anni dell’immunoterapia sublinguale allergene-specifica (SLIT) in confronto a placebo nel trattamento dell’asma pediatrico, efficacia intesa come ‘risparmio’ dell’uso di farmaci “asthma controller” (corticosteroidi inalatori e orali, broncodilatatori a lunga durata d’azione, anti-leucotrienici) e della terapia sintomatica dell’asma con broncodilatatori ad azione rapida. |
|
E.2.2 | Secondary objectives of the trial |
They will be the evaluation of:
- Asthma symptoms and signs control (by the patient’s and proxy assessment of the Asthma Control Test-ACT and Childhood-ACT, and by the Allergy Symptom Assessment – i.e. the patient’s & proxy daily diary;
- Asthma exacerbation episodes (i.e., implying the use of oral CS);
- Changes in asthma medication prescription;
- Long-term tolerability and safety profile of SLIT (frequency of adverse events- AEs and serious AEs);
- Rhinoconjunctivitis symptoms and signs (using the physician assessed clinical score) and their control through the sparing of rhinoconjunctivitis medications;
- SLIT effects on child’s and his/her family’s QoL;
- Changes in skin test reactivity patterns at Month 24;
- SLIT adherence over 24 months;
- The budget impact in the NHS perspective of pediatric allergic asthma resulting from the use of SLIT;
-To model cost-effectiveness of SLIT for the treatment of pediatric allergic asthma up to 24 months |
Valutare:
-sintomi e segni dell’asma e controllo della malattia
-episodi di esacerbazione (attacco) di asma
-variazioni nell’uso di farmaci “asthma controller”
-tollerabilità a lungo termine e profilo di sicurezza della SLIT
-sintomi e segni di rinocongiuntivite e suo controllo attraverso la SLIT nel consentire il risparmio della terapia per la rinocongiuntivite
-effetto della SLIT sulla qualità di vita del bambino e della sua famiglia
-variazioni nel profilo di reattività cutanea mediante prick test cutaneo al mese 24
-aderenza (compliance) alla SLIT nel corso dei 24 mesi di studio
-impatto economico del trattamento con SLIT nell’asma pediatrico dal punto di vista del Sistema Sanitario Nazionale;
- modello di cost-effectiveness applicato alla terapia con SLIT nell'asma allergico pediatrico a 24 mesi.

E.5 End points |
E.5.1 | Primary end point(s) |
Effectiveness of either SLIT or placebo added on to asthma SoC therapies for the allergic asthma control improvement will be evaluated by means of the percentage of children with allergic asthma who will have a reduction from baseline of at least 50% in inhaled CS (iCS) doses or a withdrawal of asthma-controller medications (i.e. responders) |
Efficacia intesa come miglior controllo dell’asma con la SLIT in confronto a placebo aggiunti alla terapia standard (farmaci “asthma controller”). Il miglioramento sarà valutato come percentuale di bambini e adolescenti con asma allergico e/o rinocongiuntivite che avranno una riduzione di almeno il 50% della dose di corticosteroidi inalatori rispetto al basale o una sospensione dell’uso di farmaci “asthma controller” . |
