Safety Study of Raltegravir in HIV/HCV Co-infected Patients

June 2, 2015 updated by: University Hospital, Bonn

An Open, Prospective Study to Compare the Safety and Efficacy of Raltegravir vs. Atazanavir / Ritonavir, Both in Combination With Tenofovir DF and Emtricitabine, in the Treatment of HIV-infection in ART Naive Subjects With HCV Co-infection.

Current European AIDS Clinical Society (EACS) guidelines for the treatment of HIV infection recommend a combination antiretroviral regimen composed of two nucleoside reverse transcriptase inhibitors plus a ritonavir boosted protease inhibitor or a non-nucleoside reverse transcriptase inhibitor.

The non-nucleoside reverse transcriptase inhibitors licensed for naïve patients - nevirapine and efavirenz - have both been asociated with increased rates of hepatotoxicity (nevirapine) and CNS toxicity (efavirenz) in HIV/HCV co-infected patients. Although PI-based therapy has dramatically reduced morbidity and mortality, it has been limited by complex dosing regimens and toxicities, leading to adherence challenges. Varying degree of liver insufficiency may necessitate pharmacokinetic monitoring of the protease inhibitor and may necessitate dose adjustments. In HIV/HCV co-infected patients HAART based on another class of antiretrovirals than NNRTI or PI may thus offer advantages with regard to adverse events and thus long-term efficacy.

The overall intention of this trial is to examine in a non-inferiority design the safety and efficacy of a raltegravir based HAART with a standard-of-care HAART in HIV-/HCV co-infected patients. The standard of care used in this study will be atazanavir/ritonavir. All patients will in addition receive a fixed combination of tenofovir and emtricitabine.

The primary end-point is the rate of hepatotoxic events, defined by ALT elevations.

Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.
Interventional

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

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
Primary objective
  1. there is no difference in the rate of grade 1/2, or 3/4 ALT elevations
  2. there is a higher incidence of grade 1 - 4 hyperbilirubinemias in the ATV/r arm

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.
