E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
Test the safety of ETR treatment in patients with FRDA (two groups of patients treated with 2 different doses: 200 mg / day and 400 mg / day). The goal is to monitor all EAs that will occur during 4 months of treatment with ETR compared to EAs recorded during 4 months of observation before and 4 months after treatment. |
Testare la sicurezza del trattamento con ETR in pazienti con FRDA (due gruppi di pazienti trattati con 2 dosi diverse: 200 mg/die e 400 mg/die). L’obiettivo si raggiungerà monitorando tutti gli EA che si verificheranno durante i 4 mesi di trattamento con ETR rispetto agli EA registrati durante 4 mesi di osservazione prima e 4 mesi dopo il trattamento. |
|
E.2.2 | Secondary objectives of the trial |
Test the effect of treatment with ETR at 2 doses (200 mg / day or 400 mg / day) comparing, in each patient, the changes recorded with the measurements of the primary and secondary efficacy endpoints observed during the three periods of the study (treatment duration , observation before and after treatment). |
Testare l’effetto del trattamento con ETR a 2 dosi (200 mg/die o 400 mg/die) confrontando, in ciascun paziente, i cambiamenti registrati con le misure di efficacia primari e secondari osservati durante i tre periodi dello studio (durata del trattamento, osservazione prima e dopo il trattamento). |
|
E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
• FRDA molecularly defined (expansion in at least one of the alleles of the FXN gene). • Absence of HIV infection (anti-HIV research negativity) • Ability to complete the cycle ergometer test with legs or arms to measure maximum exercise (the patient must be able to pedal at least 60 rpm without additional resistance for at least 3 minutes). • Willingness to participate in the study and sign the informed consent form. • Age range 10-40 years |
• FRDA molecolarmente definiti (espansione in almeno uno degli alleli del gene FXN). • Assenza di infezione da HIV (negatività ricerca AC anti HIV) • Capacità di completare il test del cicloergometro azionato con gambe o braccia per misurare l’esercizio massimale (il paziente deve essere in grado di eseguire pedalate di almeno 60 giri/min senza resistenza aggiuntiva per almeno 3 minuti). • Volontà di partecipare allo studio e firma del modulo del consenso informato. • Range di età 10-40 anni |
|
E.4 | Principal exclusion criteria |
• Pregnancy or breastfeeding in place. • Known sensitivity to the ETR or to one of its excipients. • Exposure to ETR or other experimental therapies used in FRDA (eg IFNy, erythropoietin, nicotinamide, idebenone, deferiprone, etc.). • Any previous treatments with ETR should have been interrupted at least 4 months before entering the study. • Serious medical conditions that can interfere with the absorption and distribution of the drug (liver or kidney failure, severe metabolic imbalance), major heart disease (ejection fraction <40%). • Ongoing treatment with carbamazepine, phenobarbital, phenytoin, rifampicin, rifapentine, clopidogrel, hypericum. • Positivity to the HIV test |
• Gravidanza o allattamento in atto. • Sensibilità nota all’ETR oppure ad uno degli eccipienti che lo compongono. • Esposizione all’ ETR o altre terapie sperimentali utilizzati nell’ambito della FRDA (ad es. IFNy, eritropoietina, nicotinamide, idebenone, deferiprone, ecc.). • Eventuali trattamenti precedenti con ETR dovrebbero essere stati interrotti almeno 4 mesi prima dell'ingresso nello studio. • Gravi condizioni mediche che possono interferire con l'assorbimento e la distribuzione del farmaco (insufficienza epatica o renale, grave squilibrio metabolico), patologia cardiaca importante (frazione di eiezione <40%). • Trattamento in corso con carbamazepina, fenobarbital, fenitoina, rifampicina, rifapentina, clopidogrel, iperico. • Positività al test per HIV |

E.5 End points |
E.5.1 | Primary end point(s) |
Evaluate the safety of the drug through the following assessment and consideration: • Record the presence, number and type of non severe EAs, including the results of blood and urinary tests. • Record the presence or absence of severe adverse events (SAEs) related to the administration of the investigational drug. • The study will be considered satisfactory in the absence of any SAE due to the drug. |
Valutare la sicurezza del farmaco tramite la seguente valutazione e considerazione: • Registrare la presenza, il numero e la tipologia degli EA non severi, compresi anche gli esiti degli esami ematici e urinari. • Registrare la presenza o assenza degli eventi avversi severi (SAE) correlati alla somministrazione del farmaco sperimentale. • Lo studio sarà ritenuto soddisfacente nel caso di assenza di qualsiasi SAE dovuto al farmaco. |
