1. Documented recent HCV genotype 1 infection (<=26 weeks old at the time of the baseline visit).
2. Plan to start a SOC therapy for acute HCV consisting of 24 weeks of P + R.
3. HCV RNA plasma viral load at screening >1000 IU/ml.
4. On HAART at the time of baseline visit
1. Disallowed co-medication that cannot be stopped or replaced: Several potentially life-threatening drug-drug interactions (DDI) are possible when boceprevir is combined with other drugs. Therefore ALL co-medication, including over-the-counter drugs should be checked for potential DDI with DDI table in the Dutch summary of product characteristics (SPC, appendix A). If the comedication is not mentioned in the SPC DDI table, www.HCV-druginteractions.org should be used. ;2. Contraindications for the use of full dose of peginterferon alfa-2b or ribavirin: neutrophils <0.50×10*9/l or trombocytes <25×10*9/l or a Hb <6.2mmol/L, creatinine clearance <50ml/min).;3. History of liver cirrhosis or >F1 fibrosis on fibroscan. Inclusion of patients with a chronic well-controlled HBV (HBV-DNA below the limit of detection) with tenofovir, lamivudine or emtricitabine therapy is allowed if fibroscan excludes >F1 fibrosis. Fibroscan reports <2 years old can be used for screening. Fibroscan is not required for other patients at screening.;4. HAART was started <4 weeks before baseline visit.;5. Inability to switch to a HAART regimen consisting of 2 nucleoside/tide reverse transcriptase inhibitors + Raltegravir (Isentress®) 400mg BID or atazanavir (Reyataz®) 300mg QD + ritonavir (Norvir®) 100mg QD.;6. Patient that virologically failed HAART in the past

Name Time Method <p>Sustained viral response (SVR) 12 weeks after the end of therapy in the RVR<br /><br>week 4 population (RVR4).<br /><br><br /><br>SVR at week 12 and RVR at week 4 is defined as HCV RNA below the limit of<br /><br>detection with the TaqMan 2.0 assay (Roche Diagnostics).</p><br>
- Secondary Outcome Measures
Name Time Method <p>1. SVR 12 weeks after the end of all therapy in the entire study population<br /><br>(with or without RVR at week 4).<br /><br>2. SVR 12 weeks after end of therapy in patients with already a RVR at week 1.<br /><br>3. SVR 12 weeks after end of therapy in patients starting therapy <=12weeks<br /><br>after the presumed HCV infection date versus others<br /><br>4. Alterations of biomarkers by therapy induced viral eradication: Viral<br /><br>sequencing, mutation analysis, gene expression analysis, RNA analysis and for<br /><br>Erasmus MC patients only: functional assays at the cell level.</p><br>
