| Scientific title | Short 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 acronym | Study short treatment (reduction duration) |
| Study objectives | To 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) studied | Chronic hepatitis C genotype 2 and 3 |
| Intervention | Patients 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 type | Drug |
| Phase | Phase IV |
| Drug / device / biological / vaccine name(s) | Pegylated interferon alfa-2a, ribavirin |
| Primary outcome measure(s) |
Sustained virological response (SVR) which was defined as undetectable plasma HCVRNA (less than 50 IU/ml) 24 weeks after the end of treatment. |
| Key secondary outcome measure(s) |
1. Virological response rates (HCVRNA negative in serum with a detection limit of 50 IU/ml) at the end of therapy |
| Completion date | 10/01/2008 |
