About this study
Official title: A Study to Evaluate the Erythropoietic Response in Hepatitis C Virus (HCV) Patients Receiving Combination Ribavirin (RBV)/Interferon (IFN) Therapy or RBV/PEG IFN
The purpose of this study was to describe the time course and extent of hemoglobin (Hb) changes and the erythropoietic response to PEG-IFN/RBV-induced anemia In HCV-infected subjects.
Read the detailed description
Patients receiving combination therapy for chronic hepatitis C virus (HCV) infection (standard or pegylated interferon alfa [PEG-IFN] in combination with ribavirin [RBV]) frequently develop moderate to severe anemia. In large, prospective, clinical trials of PEG-IFN alfa-2b and PEG-IFN alfa-2a, the reported mean decreases in hemoglobin (Hb) were 2.5 g/dL and 3.7 g/dL, respectively. Furthermore, in a retrospective study, 54% of standard interferon/RBV-treated patients had hemoglobin (Hb) decreases of at least 3 g/dL. It is important to understand the causes, natural history, and risk factors associated with HCV therapy-induced anemia, because such decreases in Hb can result in RBV dose reduction or discontinuation, which may adversely affect the likelihood of a virologic response. Erythropoietin is an endogenous hormone that acts in the bone marrow to increase the number of erythroid progenitor cells. Normally, a decrease in the Hb level is accompanied by an increase in the serum erythropoietin (sEPO) level, which will ultimately normalize the Hb level. The relationship between Hb and sEPO is less apparent in patients with chronic diseases such as cancer and human immunodeficiency virus (HIV) infection. It is not known whether HCV-infected patients receiving combination PEG-IFN/RBV therapy have a similarly diminished erythropoietic response to anemia.
One hundred HCV-infected patients who are receiving combination RBV/IFN or RBV/PEG-IFN therapy will be enrolled in this multicenter study. No study medication will be administered during this study. Weekly blood samples will be collected at specified times during the initial 8 weeks of RBV/IFN or RBV/PEG-IFN therapy. Assessment of laboratory tests, vital signs, incidence and severity of adverse experiences will be obtained.
The objective of this study is to document the pattern of hemoglobin changes and erythropoietic response (from baseline to final assessment, up to Week 8) in HCV-infected patients receiving combination therapy with RBV/IFN or RBV/PEG-IFN. N/A

What is this clinical trial studying?
A Phase 2 study testing Pegylated Interferon and Ribavirin in people with Hepatitis C and Anemia, run by Ortho Biotech Products, L.P..
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 5 inclusion and 11 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 19 May 2011. Status can change between updates, so confirm with the study contact before making plans.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Primary endpoints were change in Hb and sEPO from baseline to week 8 (or early withdrawal). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT00328549, which also lists 1 linked publication.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 19 May 2011.
