Scientific titleShort versus standard treatment with pegylated interferon alfa-2a plus ribavirin in patients with hepatitis C virus genotype 2 or 3: a randomised controlled trial
Study acronymStudy short treatment (reduction duration)
Study objectivesTo verify if a 12-week regimen of a combination of pegylated interferon alfa-2a and ribavirin was as efficacious as a 24-week regimen in patients with hepatitis C virus (HCV) genotype 2 or 3.
Ethics approval(s)Ethical Committee of Azienda Ospedaliera San Camillo Forlanini approved in 2005 (ref: 489)
Health condition(s) or problem(s) studiedChronic hepatitis C genotype 2 and 3
InterventionPatients fulfilling the selection criteria received in an open-label fashion pegylated interferon alfa-2a at a dose of 180 µg subcutaneously once weekly and oral ribavirin, at a dosage of 1000 mg/day (for those with a weight of less than 75 kg) or 1200 mg/day (for those with a weight of greater than or equal to 75 kg). Patients with rapid virological response (RVR) defined as HCVRNA less than 50 IU/ml after 4 weeks of treatment, were randomly assigned in a 1:1 ratio to receive a treatment either for 12 weeks. Patients without RVR were treated for a standard period of 24 weeks.
Intervention typeDrug
Pharmaceutical study type(s)
PhasePhase IV
Drug / device / biological / vaccine name(s)Pegylated interferon alfa-2a, ribavirin
Primary outcome measureSustained virological response (SVR) which was defined as undetectable plasma HCVRNA (less than 50 IU/ml) 24 weeks after the end of treatment.
Secondary outcome measures1. Virological response rates (HCVRNA negative in serum with a detection limit of 50 IU/ml) at the end of therapy
2. Severity and frequency of adverse events
