Peginterferon Alfa-2a, Ribavirin and Epoetin β in Coinfected Patients HCV/HIV Not Responding to Previous Treatment Regimens

December 3, 2019 updated by: Germans Trias i Pujol Hospital

Efficacy and Safety of High-dose Ribavirin (1600 mg/d) Boosted With Epoetin β (450 IU/kg/wk) in HIV/HCV Coinfected Patients Not Responding to Previous Treatment Regimens

This trial will assess the sustained virologic response to treatment with peginterferon alfa-2a combined with high-dose ribavirin in human immunodeficiency virus (HIV)-infected patients with hepatitis C virus (HCV) genotype 1 or 4 coinfection and persistent transaminase elevations. These patients will have been nonresponders to previous regimens with peginterferon alfa and ribavirin therapy at a dosage of 800-1200 mg/d.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

The purpose in treating chronic HCV infection in HIV-coinfected individuals is to clear HCV-RNA antibodies and cure the infection. Studies have shown that high doses of ribavirin are associated with higher response rates than those achieved with ribavirin at dosages of 800-1200 mg/d.

The main aim of this trial is to assess the sustained virologic response to treatment with peginterferon alfa-2a plus high-dose ribavirin in HIV-infected patients coinfected with HCV genotypes 1 or 4 who have had persistent transaminase elevations and lack of response to previous treatment with peginterferon alfa and ribavirin at dosages of 800-1200 mg/d.

The second aim will be to measure changes in serum HCV-RNA titers and the percentage of patients achieving serum viral loads of < 50 IU/mL during treatment. Finally, we also intend to evaluate the safety of this treatment regimen.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years to 80 years (Adult, Older Adult)

Accepts Healthy Volunteers

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Time Frame
Rate of sustained virologic response measured as serum HCV-RNA loads of < 50 IU/mL
Time Frame: 24 weeks after finishing treatment
24 weeks after finishing treatment

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Time Frame
Changes in serum HCV-RNA titers
Time Frame: between baseline and 4, 8, 12, 24, and 48 weeks after start of treatment
