E.1.1 | Medical condition(s) being investigated |
Fibrodysplasia Ossificans Progressive (FOP) is a rare genetically based disability, characterized by progressive heterotopic ossification, usually associated with congenital malformation of the toes. |
La Fibrodisplasia Ossificante Progressiva (FOP) è una malattia rara su base genetica invalidante, caratterizzata da ossificazione eterotopica progressiva, tipicamente associata a malformazione congenita degli alluci. |

E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To verify the safety and efficacy of therapy with Rosiglitazone in patients with FOP evaluating the range variation of the joint mobility of wrists, elbows, shoulders, hips, knees and ankles using both a scale from 1(free joint) to 4 (locked joint) and a measure with a protractor; To evaluate a path-test of 10 metres |
Verificare efficacia e tollerabilità della terapia con Rosiglitazone in pazienti affetti da FOP attraverso la valutazione della variazione del range di mobilità articolare di polsi, gomiti, spalle, anche, ginocchia e caviglie sia mediante una scala da 1 (articolazione completamente libera) a 4 (articolazione completamente bloccata) che mediante misura con goniometro; test al cammino su 10 metri |
|
E.2.2 | Secondary objectives of the trial |
To evaluate changes in quality of life through the SF36 questionnaire; to evaluate changes of the bone turnover biomarkers concentration during the therapy; to evaluate changes of occiput-wall, finger-floor and bimalleolar distances; to monitor the ectopic ossifications (subgroup) size using an echographic evaluation. |
Valutare le modifiche della qualità di vita valutata con SF36; variazione dei markers di turnover osseo durante terapia; variazione delle distanze occipite-muro, dito-pavimento e bi malleolare; Valutazione ecografica per monitorare la dimensione delle ossificazioni ectopiche (sottogruppo) |
