Observational Study Evaluating the Quality of Pegylated Interferon Alfa-2a and Ribavirin Treatment for Chronic Hepatitis C in Cooperation With the BNG (Association of German Resident Gastroenterologists)

2 augusti 2016 uppdaterad av: Hoffmann-La Roche

Noninterventional Study on the Quality Assurance of the Therapy of Chronic Hepatitis C With Peg-(40kd)-Interferon Alfa-2a (Pegasys®) and Ribavirin (e.g. Copegus®) With Main Focus Gastroenterologists - a Project in BNG (Association of German Resident Gastroenterologists), Part III

This observational study will examine the efficacy and safety of pegylated interferon (peginterferon) alfa-2a, mostly in combination with ribavirin treatment in chronic hepatitis C (CHC). Quality of care will also be assessed. Approximately 12% of the interferon-treated CHC patient population in Germany is expected to be studied over a period of 5 years.

Patients with CHC treated with peginterferon alfa-2a and ribavirin according to routine clinical practice

Beskrivning

Inclusion Criteria:

  • 18 years of age or over
  • Clinically diagnosed CHC with detectable virus replication
  • Women of childbearing potential should use adequate contraception. It is important that female participants of childbearing potential and their sexual partners use 2 contraceptive methods at the same time during treatment and 4 months after treatment discontinuation. During this time pregnancy tests have to be performed monthly. Particular attention is also required and pregnancy should be avoided 7 months after treatment discontinuation in female sexual partners of male participants taking ribavirin (Copegus®). Both should use adequate contraception.

Exclusion Criteria:

  • Any contraindications for peginterferon alfa-2a or ribavirin treatment
  • Pregnant or breast-feeding

RVR is defined as Hepatitis C-Virus (HCV) Polymerase Chain Reaction (PCR) assay result qualitatively negative and/or viral load ≤50 International Units/milliliter (IU/ml) at Week 4.
At Week 4
Percentage of Participants With Early Virologic Response (EVR)
Tidsram: At Week 12
EVR is defined as HCV-PCR assay result qualitatively negative and/or decline of viral load of ≥2 log levels and/or viral load ≤50 IU/ml at Week 12.
At Week 12
Percentage of Participants With End of Treatment (EOT) Response
Tidsram: Up to Week 72
EOT Response is defined as HCV-PCR assay result below limit of detection or viral load ≤50 IU/ml and/or qualitatively negative at the end of treatment.
Up to Week 72
Percentage of Participants With Sustained Virologic Response (SVR)
Tidsram: Up to Week 96

Tidsram
Percentage Cumulative Dose of Peginterferon Alfa-2a Received
Tidsram: Up to Week 96
Data for the accumulation of the cumulative dose of peginterferon alfa-2a were analyzed and reported as the percentage of the intended dose participants received. Cumulative doses were evaluated for participants for whom dosage data were documented consistently throughout the observational period. If the treatment was ongoing at the study end, the cumulative dose was aggregated for the documented observational period.
Up to Week 96
Percentage Cumulative Dose of Ribavirin Received
Tidsram: Up to Week 96
Data for the accumulation of the cumulative dose of ribavirin were analyzed and reported as the percentage of the intended dose participants received. Cumulative doses were evaluated for participants for whom dosage data were documented consistently throughout the observational period. If the treatment was ongoing at the study end, the cumulative dose was aggregated for the documented observational period.
Up to Week 96
Duration of Peginterferon Alfa-2a Therapy
Tidsram: Up to Week 72
Treatment duration was evaluated for participants for whom dates of treatment start and end of therapy were documented.
Up to Week 72
Percentage of Participants With the Most Frequent Concomitant Medications
Tidsram: At Baseline (Day 1)
Most frequent concomitant medications were defined as those, which were observed in >1 % of participants.
