Boceprevir/Peginterferon/Ribavirin for Chronic Hepatitis C: Erythropoietin Use Versus Ribavirin Dose Reduction for Anemia (P06086 AM2)
January 15, 2021 updated by: Merck Sharp & Dohme LLC
Boceprevir and Peginterferon/Ribavirin for the Treatment of Chronic Hepatitis C in Treatment-Naive Subjects: A Comparison of Erythropoietin Use Versus Ribavirin Dose Reduction for the Management of Anemia
The current trial is designed to prospectively explore the safety of erythropoietin use for the treatment of anemia during boceprevir plus peginterferon alfa-2b/Ribavirin (PEG2b/RBV) therapy and to assess its relationship to efficacy.
All participants in this trial will be treated with the triple combination of boceprevir plus PEG2b/RBV.
If a participant becomes anemic during treatment, the participant will be randomized to one of two therapeutic strategies for management of anemia (erythropoietin use versus RBV dose reduction).

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Experimental: Treated/Not Randomized
Participants received 4 weeks of PEG2b/RBV followed by 24 or 44 weeks of boceprevir plus PEG2b/RBV depending on Hepatitis C Virus RNA (HCV-RNA) levels.
Participants continued with this treatment if their serum hemoglobin remained >10 g/dL throughout the 28- or 48-week treatment period.

800 mg given three times a day (TID), orally (PO)
Other Names:
1.5 µg/kg/week given subcutaneously (SC)
Other Names:
Ribavirin weight-based dosing (WBD), 600 to 1400 mg/day given twice daily (BID), orally (PO)
Other Names:
|
Experimental: Ribavirin Dose Reduction
After the initiation of treatment with 4 weeks with PEG2b/RBV followed by 24 or 44 weeks of boceprevir, participants who became anemic (serum hemoglobin = ≤10 g/dL) within the 28- or 48-week treatment period and who were randomized to the Ribavirin (RBV) Dose Reduction Arm received reduced doses of RBV for management of the anemia in combination with PEG2b and boceprevir therapies.
