HIV Patients With Chronic Hepatitis C Genotype 1 Infection Who Failed Previously to Peginterferon /Ribavirin (BOC-HIV)

August 6, 2025 updated by: Anna Cruceta

A Study to Evaluate Safety and Efficacy of Boceprevir-response Guided Therapy in Controlled HIV Patients With Chronic Hepatitis C Genotype 1 Infection Who Failed Previously to Peginterferon /Ribavirin Eudra CT2012-003984-23

The primary objective of this study is to evaluate the safety and efficacy of a Response Guided Therapy of boceprevir 800 mg dosed three times a day (TID) orally (PO) in combination with Peginterferon (either alpha 2b or alpha 2a) and Ribavirin in HIV/HCV genotype 1 infected patients that failed to previous HCV therapy.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.

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

In a total number of 108 patients the protocol was evaluated but only in 102 the protocol efectively was presented. In the remaining 6 patients we don't believe the trial could be performed.

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.

  • Subject must weight between 40 kg and 125 kg.
  • Subject and subject's partner(s) must each agree to use acceptable methods of contraception for at least 2 weeks prior to Day 1 and continue until at least 6 months after last dose of study drug.
  • Subjects must be willing to give written informed consent and by investigator opinion be able to follow the protocol visit design.

Exclusion Criteria:

  • Subjects known to be coinfected with hepatitis B virus (HBsAg positive).
  • Patients chronically infected with HCV genotype other than 1

  • Plasma HIV RNA more than 50 copies/mL
  • Platelet count less than 80.000 /mm3
  • Subjects who required discontinuation of previous interferon or ribavirin regimen for a severe adverse event considered by the investigator to be possibly or probably related to ribavirin and/or interferon.
  • Treatment with ribavirin within 90 days and any interferon-alpha within 1 month of Screening.
  • Treatment for hepatitis C with any investigational medication. Prior treatments with herbal remedies with known hepatotoxicity are exclusionary.
  • Participation in any other clinical trial within 30 days of randomization or intention to participate in another clinical trial during participation in this study.
  • History of hemoglobinopathy (e.g., thalassemia) or any other cause of or tendency to hemolysis.
  • Evidence of decompensate liver disease including, but not limited to, a history or presence of clinical ascites, bleeding varices, or hepatic encephalopathy.
  • Diabetic and/or hypertensive subjects with clinically significant ocular examination findings.

  • Any known pre-existing medical condition that could interfere with the subject's participation in and completion of the study.
  • Any current evidence of substance abuse of alcohol or other drugs.
  • Subjects receiving opioid agonist substitution therapy but not enrolled in an opiate substitution maintenance program.

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
Measure Description
Time Frame
Achievement of Sustained Virological Response (SVR) at 24 Weeks Post-Treatment
Time Frame: Week 24

Achievement of SVR, defined as undetectable plasma HCV-RNA at Follow-up Week (FW) 24.

If a subject is missing FW 24 data and has undetectable HCV-RNA level at FW 12, the subject would be considered an SVR.
Week 24

Secondary Outcome Measures

Secondary Outcome Measures
