NCT04920539

Brief Summary

In this study, the investigators hypothesize that THC alters the immunogenome in a cell type-specific fashion and alters cytokine production via epigenetic regulatory mechanisms and that these alterations differ between HIV-infected and HIV-uninfected host genomes.

Outcome Measures

Primary Outcomes (4)

  • Change in Gene Expression Alteration

    Quantity of each gene is measured via sequence transcriptome, and significant differences of quantified gene pre- and post-THC infusion will be identified as THC-induced gene expression alteration.

    Blood samples will be collected to measure changes in gene expression altered by THC before study drug infusion and at 70, 140, and 300 minutes after study drug infusion.

  • Change in Cytokine Profile

    Cytokine profile will be measured using Luminex Performance Human Cytokine Discovery panel before and after study drug infusion. The 45 cytokines selected based on their established role in immune functioning are: CCL2/MCP-1, CCL3/MIP-1a, CCL4/MIP-1b, CCL5/RANTES, CCL11/Eotaxin, CCL19/MIP-3b, CCL20/MIP-3a, TNFSF5, CX3CL1/Fractalkine, CXCL1/GROa, CXCL2/GROb, CXCL10/IP-10, EGF, FGF2, FLT3L, G-CSF, GM-CSF, Granzyme B, IFN-a2, IFN-b, IFN-g, IL-1a, IL-1b, IL-1ra, IL-2, IL-3, IL-4, IL-5, IL-6, IL-7, IL-8/CXCL8, IL-10, IL-12 p70, IL-13, IL-15, IL-17A, IL-17E, IL-33, PD-L1, PDGF-AA, PDGF-AB/BB, TGF-a, TNF-a, TNFSF10, VEGF.

    Blood samples will be collected to measure changes in cytokine profile before study drug infusion and at 70, 140, and 300 minutes after study drug infusion.

  • Change in Gene Expression Alteration by THC between HIV-positive and HIV-negative Groups

    Quantity of each gene is measured via sequence transcriptome, and significant differences of quantified gene pre- and post-THC infusion are identified as THC-induced gene expression alteration. Results will be compared between HIV-positive and HIV-negative subjects.

    Blood samples will be collected to measure change in gene expression altered by THC before study drug infusion and at 70, 140, and 300 minutes after study drug infusion.

  • Change in Cytokine Profile by THC between HIV-positive and HIV-negative Groups

    Cytokine profile will be measured using Luminex Performance Human Cytokine Discovery panel before and after study drug infusion. Results will be compared between HIV-positive and HIV-negative subjects. The 45 cytokines selected based on their established role in immune functioning are: CCL2/MCP-1, CCL3/MIP-1a, CCL4/MIP-1b, CCL5/RANTES, CCL11/Eotaxin, CCL19/MIP-3b, CCL20/MIP-3a, TNFSF5, CX3CL1/Fractalkine, CXCL1/GROa, CXCL2/GROb, CXCL10/IP-10, EGF, FGF2, FLT3L, G-CSF, GM-CSF, Granzyme B, IFN-a2, IFN-b, IFN-g, IL-1a, IL-1b, IL-1ra, IL-2, IL-3, IL-4, IL-5, IL-6, IL-7, IL-8/CXCL8, IL-10, IL-12 p70, IL-13, IL-15, IL-17A, IL-17E, IL-33, PD-L1, PDGF-AA, PDGF-AB/BB, TGF-a, TNF-a, TNFSF10, VEGF.

    Blood samples will be collected to measure changes in cytokine profile by THC before study drug infusion and at 70, 140, and 300 minutes after study drug infusion.

Secondary Outcomes (4)

  • Perceptual Alterations

    Perceptual alterations will be measured before study drug infusion and 70, 140, and 300 minutes after study drug infusion.

  • Cannabis Subjective Effects

    Cannabis subjective effects will be measured before study drug infusion and 70, 140, and 300 minutes after study drug infusion.

  • Cannabinoid Relevant Molecules

    Blood will be collected before study drug infusion and at 70, 140, and 300 minutes after study drug infusion.

  • Change in total immediate recall on the RAVLT.

    The RAVLT will be administered prior to study drug administration at approximately 25 minutes after study drug administration.
