E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To determine the efficacy of PSI-7977 in combination with RBV administered for 12 weeks compared with PEG/RBV administered for 24 weeks in treatment-naïve patients with HCV genotype 2 or 3 as assessed by the rate of SVR12 (HCV RNA <LOQ 12 weeks after cessation of therapy). |
Determinare l’efficacia di PSI-7977 in associazione con RBV somministrato per 12 settimane in confronto a PEG/RBV somministrato per 24 settimane a pazienti naïve al trattamento, con infezione da HCV di genotipo 2 o 3 come risulta dalla valutazione del tasso di RVS12 (HCV RNA <LOQ 12 settimane dopo la cessazione della terapia). |
|
E.2.2 | Secondary objectives of the trial |
•To assess the safety and tolerability of PSI-7977/RBV administered for 12 weeks as measured by the frequency of deaths, serious adverse events (SAEs), discontinuations due to AEs, and Grade 3 or 4 laboratory abnormalities •To determine the SVR at Week 24 (SVR24) following completion of treatment for each investigational arm (HCV RNA <LOQ 24 weeks after cessation of therapy) •To evaluate the change in circulating HCV RNA in patients over 12 or 24 weeks of dosing •To determine the proportion of patients with HCV RNA below the lower limit of quantitation (LOQ) and lower limit of detection (LOD) at various time points thoughout the study •To determine the proportion of patients whose ALT normalizes during therapy •To describe rates of virologic failure •To characterize HCV drug resistance substitutions at baseline, during, and after therapy with PSI-7977. |
•Valutare la sicurezza e tollerabilità di PSI-7977/RBV somministrato per 12 settimane sulla base della frequenza dei decessi, degli eventi avversi seri (SAE - Serious Adverse Events), dell’abbandono dovuto ad eventi avversi e dei risultati anomali di laboratorio di grado 3 o 4 •Determinare la RVS alla Settimana 24 (RVS24) dopo la fine del trattamento di ciascun braccio sperimentale (HCV RNA <LOQ 24 settimane dopo la cessazione della terapia) •Valutare la variazione nella quantità di HCV RNA in circolo nei pazienti nell’arco di 12 o 24 settimane di somministrazione •Determinare la proporzione di pazienti affetti da infezione da HCV RNA al di sotto del limite inferiore di quantificazione (LOQ - limit of quantitation) e del limite inferiore di rilevabilità (LOD - limit of detection) in diversi momenti nel corso dello studio.

E.3 | Principal inclusion criteria |
1) Males or females at least 18 years old, or the legal age of consent, whichever is older, at Screening. Subjects or their heterosexual partner(s) must either be of non-childbearing potential or they must use effective contraception from 2 weeks before the initiation of therapy until 6 months (or the duration recommended locally for ribavirin if longer) after the last dose of study medication. 2) Chronic Genotype 2 or 3 HCV-infection documented by at least one measurement of serum HCV RNA ≥ 10,000 IU/mL 3) Patients with Childs A cirrhosis may be included (up to 20% of patients randomized) 4) Subjects must be naïve to all HCV antiviral treatment(s), including but not limited to immunomodulatory and nucleoside/tide treatments for chronic HCV infection. 5) A body mass index (BMI) of ≥18kg/m2 6) Otherwise suitable for participation as determined by the medical history, physical examination, ECG, and clinical laboratory measurements performed at Screening 7) Able to effectively communicate with the Investigator and other center personnel. Willing to give written informed consent and comply with the study restrictions and requirements. |
1) maschi o femmine di almeno 18 anni di età, al momento dello screening. I soggetti oi loro partner eterosessuali (s) non devono essere in grado di concepire o devono utilizzare un contraccettivo efficace da 2 settimane prima dell'inizio della terapia fino a 6 mesi (o durata raccomandata a livello locale per la ribavirina, se più lunga) dopo l'ultima dose dei farmaci in studio. 2)infezione documentata cronica da HCV genotipo 2 o 3 da almeno una misurazione di HCV RNA nel siero ≥ 10.000 UI/mL 3) I pazienti con cirrosi A Childs possono essere inclusi (fino al 20% dei pazienti randomizzati) 4) I soggetti devono essere naive a tutti i trattamenti antivirali per HCV inclusi ma non solo i trattamenti immunomodulatori e nucleoside/tide per infezione cronica da HCV. 5) Un indice di massa corporea (BMI) ≥ 18kg/m2 6) In caso contrario, adatto per la partecipazione come stabilito dalla anamnesi, esame fisico, ECG, e misurazioni cliniche di laboratorio effettuate al momento dello screening 7) In grado di comunicare efficacemente con lo sperimentatore e l'altro personale del centro. Disposto a dare il consenso informato scritto e rispettare le restrizioni e i requisiti dello studio. |
|
E.4 | Principal exclusion criteria |
1) Positive test at Screening for HBsAg, anti-HBc IgM Ab, or anti-HIV Ab. 2) History of any other clinically significant chronic liver disease. 3) A history of consistent with decompensated liver disease including ascites, variceal hemorrhage, hepatic encephalopathy, hepatorenal syndrome and hepatopulmonary syndrome, among others. 4) History or current evidence of psychiatric illness, immunologic disorder, hemoglobinopathy, pulmonary or cardiac disease, seizure disorder or anticonvulsant use, poorly controlled diabetes, cancer, or a history of malignancy that in the opinion of the investigator makes the patient unsuitable for the study. Chronic medical conditions, especially if treated with medications (such as hypertension), must be stable at the time of screening. No new therapies should be started prior to the study that may confound the assessment of study drug safety. 5) Clinical signs and symptoms of acute pancreatitis with elevated lipase. |
1) Test positivo allo screening per l'HBsAg, Ab anti-HBc IgM, o anti-HIV Ab. 2) Storia o evidenza di altra malattia cronica del fegato clinicamente significativa. 3)Storia di malattia epatica scompensata tra cui ascite, emorragia da varici esofagee, encefalopatia epatica, sindrome epato-renale e la sindrome epatopolmonare, tra le altre. 4) Storia o attuale malattia psichiatrica, disturbi immunologici, emoglobinopatie, malattie polmonari o cardiache, disturbi convulsivi o uso di anticonvulsivante, diabete scarsamente controllato, cancro o una storia di tumore maligno che, a giudizio dello sperimentatore rende il paziente inadatto al studio. Condizione medica cronica, specialmente se trattate con farmaci (come ipertensione), deve essere stabile al momento dello screening. Non devono essere iniziate nuove terapie prima dello studio che possono confondere la valutazione della sicurezza del farmaco in studio. 5)segni clinici e sintomi di pancreatite acuta con lipasi elevata. |

|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
The primary study hypothesis is that PSI-7977/RBV administered for 12 weeks will be superior to PEG/RBV administered for 24 weeks. The primary efficacy endpoint is sustained viral response 12 weeks post last dose of any treatment (HCV RNA <LOQ 12 weeks after cessation of therapy) in the ITT population. The primary analyses will include the assessments non-inferiority (with a non-inferiority margin of 15%) and the superiority PSI-7977/RBV (Arm A) to the control (Arm B). A closed testing procedure will be performed for the primary analyses |
L'ipotesi principale dello studio è che PSI-7977/RBV somministrato per 12 settimane sarà superiore al PEG/RBV somministrati per 24 settimane. L'endpoint primario di efficacia è la risposta virale sostenuta alle 12 settimane dopo l'ultima dose di qualsiasi trattamento (HCV RNA <LOQ 12 settimane dopo l'interruzione della terapia) nella popolazione ITT. Le analisi primarie comprendono le valutazioni di non-inferiorità (con un margine di non inferiorità del 15%) e la superiorità di PSI-7977/RBV (braccio A) rispetto al controllo (braccio B). Una procedura di test chiuso sarà effettuata per le analisi primarie. |
