Brief Summary

This study tests whether galantamine (GAL) reduces HIV-related inflammation and cognitive deficits. In this double-blind placebo-controlled crossover study, HIV-infected individuals (N=120; 60 smokers and 60 non-smokers) will be randomized to 12 weeks of GAL or placebo, followed by a 4-week washout, then 12 weeks of GAL or placebo (arms switched). Outcomes are monocyte/macrophage and T cell activation and neurocognitive performance.

Detailed Description

Although anti-retroviral therapy (ART) enhances life expectancy and overall quality of life (QoL), HIV-infected individuals are increasingly vulnerable to non-AIDS-related diseases including HIV-associated neurocognitive disorders (HAND). Inflammation is a primary mechanism in the pathogenesis of HAND and tobacco use may further exacerbate inflammation. Conversely, nicotine alone has anti-inflammatory effects suggesting that stimulating the cholinergic pathway via pharmacological treatment [e.g., galantamine (GAL)] may suppress inflammation and reverse or prevent neurocognitive deficits in HIV-1 infection. In this double-blind, placebo-controlled crossover study, HIV-infected individuals (N=120; 60 smokers, 60 nonsmokers) will be randomized to 12 weeks of GAL or placebo, followed by a 4-week washout, then 12 weeks of GAL or placebo (arms switched). All subjects will be stable on ART and the GAL dose will follow FDA guidelines. At the beginning and end of each treatment phase, inflammatory biomarkers and viral load will be assessed. Monocyte transcriptomics will also be assessed on a subset of the sample (n=60; 30/group). Neurocognition and clinical outcomes (e.g., QoL) will be measured at baseline and at 4-week intervals during each treatment phase. The primary outcomes are monocyte/macrophage and T-cell activation (CD16, CD163, and CC chemokine receptor type 2 or CCR2 expression; plasma CC chemokine ligand type 2 or CCL2 [MCP-1 or monocyte chemoattractant protein-1], sCD14; CD38/HLA-DR [cluster of differentiation 38/Human Leukocyte Antigen- antigen D Related] on CD8 [cluster of differentiation 8] cells) and neurocognitive performance (processing speed, verbal learning/memory, executive function). Exploratory outcomes include monocyte gene expression patterns and broad plasma cytokine analysis. This study will provide insight into the interactions among nAChR activation, HIV immune activation and pathogenesis, and tobacco use and has translational and therapeutic implications that could improve health outcomes among HIV-infected individuals.

Study Groups

Galantamine first

This is a crossover study such that all participants receive both placebo and galantamine. Participants were randomized to receive galantamine first and placebo second. Timepoints Week 0 through Week 12 represent the first period and Weeks 16 through 28 represent the second period.

This study follows the FDA-recommended dosing regimen for galantamine extended release (GAL ER): 4 weeks at 8 mg (once a day), 4 weeks at 16 mg (once a day), and 4 weeks at 24 mg (once a day).

The University of Pennsylvania Investigational Drug Service (IDS) will oversee the randomization of all study medication, purchase study medication, manufacture matched placebo, encapsulate and package them in blister packs to maintain double-blind procedures.

Group Type: EXPERIMENTAL

Galantamine

Intervention Type: DRUG

The study will be performed using the 8mg, 16mg and 24mg doses of galantamine hydrobromide-ER. The dosing regimen will be an initial 4 weeks of drug run-up at the lowest 8mg q.d. dose, followed by 16mg q.d. for the following 4 weeks, and the dose will be increased for the last 4 weeks to 24mg. Participants will be instructed to take one 8mg 16mg or 24mg pill (galantamine-ER or placebo) every morning, preferably with food.

Placebo

Intervention Type: DRUG

Matched placebo will be made in-house using lactulose filler in gel capsules. Participants will be instructed to take one pills every morning for 12 weeks.

Placebo first

This is a crossover study such that all participants receive both placebo and galantamine. Participants were randomized to receive galantamine first and placebo second. Timepoints Week 0 through Week 12 represent the first period and Weeks 16 through 28 represent the second period.

Placebo ingredients will be purchased, encapsulated, and packaged into blister packs by the IDS at the University of Pennsylvania. Both active medication and placebo will look identical.

The study medication assignments for each participant in this project is randomized and counterbalanced. This means that approximately 50% of participants will take galantamine during the first medication period, followed by the placebo in the second medication period. Alternatively, approximately 50% of participants will take the placebo during the first medication period, followed by galantamine during the second medication period.
