About this study

Official title: Comparison of Standard Therapy,Peginterferon Alpha-2a + Ribavirin for 48 Weeks VS Peginterferon Alph-2a + Ribavirin + Betaine for 12 Weeks Followed by 36 Weeks Standard Therapy in Untreated Adults With Chronic Hepatitis C Genotype 1

The primary purpose of the study is to compare the safety and effectiveness of standard treatment for chronic hepatitis C using peginterferon alpha-2a (Pegasys) and ribavirin (Copegus) to those same medications plus a dietary supplement called betaine when added for the first 12 weeks of treatment.

Peginterferon alpha-2a (Pegasys) and ribavirin (Copegus) are approved by the FDA (Food and Drug Administration) for the treatment of chronic hepatitis C.

Betaine is a dietary supplement and occurs naturally in the body. It is not a medication regulated by the FDA or an approved drug for chronic hepatitis C.

Read the detailed description

Although pegylated alpha interferon and ribavirin will likely be part of the core therapy for chronic HCV for the next several years, there are a number of complimentary antiviral agents in development including protease or polymerase inhibitors, RNA vaccines and immunomodulators (5). However, it would be unlikely to have FDA approval for any of these newer agents before the next 3 - 5 years, i.e. 2010-2012.

Betaine, a naturally occurring anti-oxidant metabolite of choline and an amino acid analog (tri-methyl-glycine), serves as a methylation agent to re-methylate damaged cell proteins or enzymes (6). By virtue of its metabolic role in decreasing toxic metabolites, betaine also protects against alcohol-induced fatty liver and apoptosis. Recently, pilot studies performed both at the Mayo Clinic and here at UNMC showed its applicability as a treatment of non-alcoholic fatty liver in human subjects (7, 8).

Betaine has also recently been found to promote interferon function by overcoming HCV - induced inhibition of interferon signaling (9). Naturally-occurring HCV proteins during human infection can hypo-methylate proteins integral to the Jak - STAT (signal transducers and activators of transcription) pathway, thereby inhibiting the antiviral activity of interferon. In cultured cells betaine administration, in a physiologically attainable concentration, restored STAT methylation and improved interferon signaling (9).

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 11 inclusion and 16 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: withdrawn, as of the sponsor's last update on 15 Aug 2023. 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.

Are results available for this study?

The study was withdrawn before enrolling participants, so there are no results.

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?

Sustained Viral Response 24 weeks following the end of anti-viral therapy (time frame: 72 weeks). 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 NCT00571714, 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 15 Aug 2023.
