Post-marketing Surveillance of Children With Chronic Hepatitis C Treated With Intron A (Vial or Pen) and Rebetol (Study P04397)(TERMINATED)

This study has been terminated.
(Study halted due to low recruitment. The 3 participants at time of termination transferred into study P04538 (NCT00727077). See NCT00727077 for details/results.)

The objective of the study is to assess the safety and efficacy of Intron A (3 Mio I.E./m2, 3 times per week) and Rebetol (15 mg/kg/day) in children aged 3 to 17, treated in common medical practice at 10 sites in Germany. The primary objective is to determine if there are any new severe adverse events observed with this recently approved dosing regimen. The study will also evaluate the rates of eradication of the HCV virus.

This study was terminated due to low enrollment. At the time of termination, 3 participants had enrolled. Therefore, these 3 participants transferred into study P04538 (NCT00727077) and will be included in the P04538 (NCT00727077) data reporting.
