E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To assess the clinical effects of thalidomide therapy on the severity of epistaxis in subjects with HHT who are refractory to standard therapies. |
Valutare gli effetti della terapia con talidomide sulla severità dell’epistassi in soggetti con HHT refrattari ai trattamenti standard. |
|
E.2.2 | Secondary objectives of the trial |
- Safety and Tolerability - To ascertain whether thalidomide reduces telangiectasias in nasal mucosa - To assess specific biological and clinical parameters predictable for patients response and side effects profile. |
- Sicurezza e tollerabilità del farmaco - Valutare se la talidomide riduce le teleangiectasie a livello della mucosa nasale - Valutare specifici parametri biologici e clinici predittivi di risposta alla terapia e comparsa di effetti collaterali |
