May 2, 2014 updated by: University of California, San Francisco

Interaction of Alcohol & HAART in HIV/AIDS and HIV/AIDS With HCV Co-Infection

The proposed studies will examine the extent of pharmacokinetic and pharmacodynamic interactions between alcohol and various antiretroviral therapies in those with HIV/AIDS, HIV/HCV co-infection, mild HCV and healthy subjects.

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 goal of this research study is to improve the clinical care of human immunodeficiency virus (HIV)-infected or HIV/Hepatitis C (HCV) co-infected, alcohol-using patients by identifying significant interactions which may occur between drugs commonly used to treat HIV disease known to be cytochrome P450 (CYP450) inducers or inhibitors and alcohol, the most frequently abused substance in the United States. We hypothesize that concomitant use of alcohol and currently utilized antiretroviral therapy (ART) will be associated with significant drug interactions including alteration of alcohol and ART pharmacokinetics as well as altered responses to alcohol administration. We plan to conduct alcohol and ART administration studies in 6 study samples (n=10 each): 1. those with HIV/AIDS and eligible for efavirenz-containing HAART, 2. those with HIV/AIDS and eligible for a ritonavir-boosted protease inhibitor based HAART, 3. those with HIV/AIDS and HCV eligible for an efavirenz-containing HAART, 4. those with HIV/AIDS and HCV eligible for a ritonavir-boosted protease inhibitor regimen, 5. healthy subjects taking clinically relevant doses of maraviroc and 6. those with mild HCV taking clinically relevant doses of maraviroc. Pharmacokinetics, subjective, and cognitive data will be serially collected over the course of study sessions where either alcohol or placebo is administered prior to and following ART. Data collected will elucidate the presence and clinical significance of drug interactions, both pharmacokinetic and pharmacodynamic, between alcohol and ART in these populations.

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

21 years and older (ADULT, OLDER_ADULT)
