About this study

Official title: Efficacy of High Doses of Both Pegylated Interferon Alfa-2a and Ribavirin for Retreatment of HIV-coinfected Patients With Liver Cirrhosis Due to HCV Genotype 1 or 4 Nonresponders to Previous Standard Therapy.

Objective: To evaluate the efficacy and safety of high doses of both peginterferon-alfa 2a (360 ug per week) plus ribavirin (800 mg b.i.d.) in HIV-infected patients with compensated liver cirrhosis by HCV genotype 1 or 4 without previous virological response(*) to a standard dose treatment of both drugs.

(*) Non previous virological response: no decrease of plasma RNA-HCV at least 2 log10 after 12 weeks in treatment or breakthrough viremia while on treatment.

Additionally, this study will evaluated the influence of simultaneous peginterferon-alfa 2a and ribavirin plasma concentrations on early viral response (EVR) and sustained viral response (SVR) in these patients.

Method: Pilot clinical trial, phase II-III, open labeled multicenter in which patients from several hospitals of the Servicio Andaluz de Salud will be enrolled.

The usual clinical and analytical follow up will be performed but additional blood samples will be obtained for determination of interferon and ribavirin plasma levels. The primary end point will be a sustained virologic response (defined as an undetectable serum HCV-RNA after 24 weeks after the cessation of treatment). Likewise, rapid virological response (at 4 weeks of treatment), early virological response (at 12 weeks), and end of treatment response rates will be evaluated as well as their relationships with the plasma interferon an ribavirin concentrations determined by ELISA and HPLC, respectively. The safety and tolerability of the studied medications will be evaluated by means of clinical adverse events, physical examination and laboratory results. The evolution of liver fibrosis will be evaluated comparing the basal and end of treatment results of transient elastometry.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Pegylated interferon alfa-2a and RibavirinDrug

    Also called Pegasys, Copegus

    Pegylated interferon alfa-2a (360 ug per week) plus oral Ribavirin (800 mg b.i.d.) for 48 or 72 weeks. The treatment will be discontinued for patients who did not achieve a reduction with respect to baseline of at least 0.5 log10 IU/ml in plasma RNA-HCV levels at week 4 or 2 log10 UI/ml at week 12 and will be considered as viral failures.

    Duration: 48 weeks for patients reaching an undetectable plasma RNA_HCV at week12 and 72 weeks for those without a negative viremia at week 12 but a reduction of at least 2 log10 IU/ml in RNA-HCV levels.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Sustained viral response (undetectable serum HCV-RNA)

    Measured: Throughout treatment and 24 weeks after finishing it

Secondary outcomes (3)
  1. Relationships between the plasma interferon an ribavirin concentrations and efficacy

    Measured: Throughout treatment and 24 weeks after finishing it.

  2. safety and tolerability of the studied medications

    Measured: Throughout treatment and 24 weeks after finishing it

  3. The evolution of liver fibrosis will be evaluated comparing the basal and end of treatment results of transient elastometry

    Measured: baseline and after finishing treatment

Questions about this trial

What is this clinical trial studying?

A Phase 2/3 study testing Pegylated interferon alfa-2a and Ribavirin in people with Liver Cirrhosis and Hepatitis C Virus, run by Sociedad Andaluza de Enfermedades Infecciosas at 4 sites in Spain.

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 4 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: finished, as of the sponsor's last update on 30 Dec 2011. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 4 sites in Spain. Whether a site is taking part right now should be confirmed with that site. See every site.

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 combined 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.

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

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?

Sustained viral response (undetectable serum HCV-RNA) (time frame: Throughout treatment and 24 weeks after finishing it). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 30 Dec 2011.
