HIV Clinical Trial
Official title:
Cannabis Effects on Antiretroviral Therapy Pharmacokinetics and Neurotoxicity
This study will address whether cannabis affects antiretroviral therapy (ART) drug concentrations, mood, and thinking. The project will have two phases. Phase 1 is an observational study, in which 120 people will be assessed to evaluate the effects of chronic cannabis use on ART drug concentrations, mood, and thinking. In Phase 2, the study will administer cannabis (or placebo) to 40 people to examine its acute effects on ART drug concentrations.
People with human immunodeficiency virus (HIV) commonly use cannabis but whether cannabis affects the antiretroviral therapy (ART) that treats HIV is not well known. Cannabis can inhibit the activity of enzymes that metabolize and eliminate ART drugs from the body, which could result in higher concentrations of ART drugs in the body. Cannabis may also affect the distribution of ART drugs into the brain, which could have both beneficial (e.g., better HIV control) and detrimental (e.g., toxicity) effects. The effects of cannabis may are likely influenced by factors like how much is used (e.g., light vs. heavy use) and the route of use (e.g., smoked vs. ingested). This study will address whether cannabis affects ART concentrations in blood and cerebrospinal fluid as well as mood, and thinking. The project will have two phases. Phase 1 is an observational study, in which 120 people will be assessed once to evaluate the effects of chronic cannabis use on ART drug concentrations, mood, and thinking. In Phase 2, the study will administer cannabis (or placebo) to 40 people to examine its acute effects on ART drug concentrations. ;
