E.2.1 | Main objective of the trial |
To evaluate the efficacy of daily oral doses of 400 mg or 500 mg of SAR302503 (Investigational Medicinal Product, IMP) compared to placebo in the reduction of spleen volume as determined by magnetic resonance imaging (MRI) (or computed tomography scan in patients with contraindications for MRI). |
•Dimostrare l’efficacia di SAR302503 (farmaco sperimentale) somministrato una volta al giorno per via orale alle dosi di 400 o 500 mg in confronto a placebo nel ridurre il volume della milza misurato mediante risonanza magnetica (o TAC in caso i pazienti abbiano controindicazioni alla risonanza magnetica). |
|
E.2.2 | Secondary objectives of the trial |
To evaluate the effect on Myelofibrosis (MF)-associated symptoms (key MF symptoms) as measured by the modified Myelofibrosis Symptom Assessment Form (MFSAF) diary. To evaluate the Overall Survival of patients treated with either 400 mg/day or 500 mg/day of IMP as compared to placebo. To evaluate the Progression Free Survival of patients treated with either 400 mg/day or 500 mg/day of IMP as compared to placebo. To evaluate the durability of splenic response. To evaluate the safety of IMP |
•Misurare gli effetti sui sintomi associati alla mielofibrosi (sintomi chiave della mielofibrosi), utilizzando il diario “Myelofibrosis Symptom Assessment Form (MF-SAF)”.
