Participant Flow

687 Participants enrolled and were treated with Peginterferon/Ribavirin (PEG2b/RBV) followed by PEG2b/RBV + boceprevir. 500 participants became anemic during treatment and were randomized to either the RBV Dose Reduction Arm (n=249) or the Erythropoietin Use Arm (n=251).

Measure
Ribavirin Dose Reduction Arm
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.
Erythropoietin Use Arm
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 Erythropoietin Use Arm received erythropoietin for management of the anemia in addition to PEG2b/RBV and boceprevir therapies.
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.

Measure
Ribavirin Dose Reduction Arm
n=249 participants at risk
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.
Erythropoietin Use Arm
n=251 participants at risk
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 Erythropoietin Use Arm received erythropoietin for management of the anemia in addition to PEG2b/RBV and boceprevir therapies.
Treated/Not Randomized
n=187 participants at risk
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.
