About this study
Official title: Evaluation of Clinical, Virologic and Immunologic Factors That Contribute to the Pathogenesis of Chronic Hepatitis C and Its Complications
This study will collect quantities of white blood cells from patients infected with the hepatitis C virus (HCV) for research on the interactions between HCV and the human immunodeficiency virus (HIV) in people infected with both of these agents. Several studies have shown that infection with HIV adversely affects liver disease due to HCV.
Patients 18 years of age and older who are infected with both HCV and HIV or with HCV alone may be eligible for this study. Candidates must not have liver failure and must not be undergoing treatment for HCV at the time of enrollment.
Participants will undergo leukapheresis to collect white blood cells. This procedure allows collection of larger numbers of cells than would be possible with simple blood drawing. For the procedure, blood is removed through a needle in the vein of one arm and spun in a machine that separates the blood into its components. The white cells are extracted and the rest of the blood is re-infused through the same needle or through a needle in the other arm. The procedure takes approximately 1-3 hours, depending on the amount of white cells being collected. A maximum of three leukapheresis procedures are done. If additional procedures are required, the patient will sign a new consent form. Procedures will be limited to no more than three times a year, or once every 4 months.
Read the detailed description
Hepatitis C virus (HCV) and Hepatitis B (HBV) infection are known to cause morbidity and mortality especially among those who are coinfected with Human Immunodeficiency virus (HIV). HCV infected individuals who are also coinfected with HIV have more rapid progression of liver disease, abnormal diagnostic serologies, higher levels of HCV viremia, and markedly lower levels of therapeutic responses to the standard combination therapy with peginterferon and ribavirin.
The underlying immunopathogenesis of HCV and HBV infection, progression of liver disease, and interactions with HIV are not yet clearly understood. A clear understanding of the immune correlates of protection against HCV and HBV are important in development of a vaccine for HCV and novel immune-based therapeutics for the cure of HBV.
This study will recruit individuals who are coinfected with HIV and HCV and/or HBV as well as those who are monoinfected with HCV or HBV. The study will enroll 2 groups. Participants in the first group (hereafter referred to as Group 1) will consist of participants recruited for research and clinical related blood draws, leukapheresis, and liver biopsies for long term study participation. Participants in the second group (hereafter referred to as Group 2) will consist of participants with known or suspected HCV and/or HBV who need assistance with diagnosis or treatment.
Participants in Group 1 will be apheresed or undergo blood draw several times after enrollment and may be followed for up to 10 years. Participants in Group 2 will be evaluated for HBV and/or HCV infection or complications, or receive treatment. The expectation is that may be followed for one year.
Leukapheresis is used in Group 1 in order to obtain sufficient cells to pursue the following objectives: delineating B cell response to CD4+ T cell help, delineating CD8+ T factors associated with suppression of viral replication and normalization of immune function, characterizing natural killer function relative to HCV and/or HBV disease, and identifying biomarkers for progression of liver disease. The required number of mononuclear cells needed to perform these experiments can be easily and safely obtained using leukapheresis procedures in the Clinical Center Apheresis Unit. Participants who do not meet apheresis criteria may participate through routine blood draws to contribute to this research. All participants in Group 1 may also receive a liver biopsy at NIH (every 3 years for HIV/HCV coinfected and all HBV infected and every 5 years for HCV monoinfected subjects) to assess the progression of liver disease.
Treatment plans for Group 2 HBV and/or HCV will be in accordance with standard medical practice, and the number and length of additional visits and diagnostic evaluations will vary accordingly.

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.
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.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT00076427, which also lists 3 linked publications.
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 6 Oct 2017.
