Body Compartment Pharmacokinetics of Anti-retroviral Agents That May be Considered for Future On-demand Peri-exposure HIV Prophylaxis Regimens

Completed · Phase 1

Conditions studied: HIV/AIDS

In brief

This study is being conducted to determine if the uptake of anti-HIV medication, called Genvoya®, at different time-frames, is different at several body sites, including mucosal tissues. This medication might be considered for on-demand PEP regimens in the future.

• Platelet count <100,000
• Creatinine clearance <60
• HBsAg reactive
• Any known medical condition that, in the judgment of the investigators, increases the risk of local or systemic complications of endoscopic procedures or pelvic examination, including but not limited to:
• Uncontrolled or severe cardiac arrhythmia
• Recent major abdominal, cardiothoracic, or neurological surgery
• History of uncontrolled bleeding diathesis
• History of colonic, rectal, or vaginal perforation, fistula, or malignancy
• History or evidence on clinical examination of ulcerative, suppurative, or proliferative lesions of the anorectal mucosa, or untreated sexually transmitted disease with mucosal involvement
• Continued need for, or use during the 14 days prior to enrollment, of the following medications:
• Aspirin or more than 4 doses of NSAIDs
• Warfarin, heparin (low-molecular weight or unfractionated), platelet aggregation inhibitors, or fibrinolytic agents
• Any form of rectally administered agent besides lubricants or douching used for sexual intercourse
• Continued need for, or use during the 90 days prior to enrollment, of the following medications:
• Systemic immunomodulatory agents
• Supraphysiologic doses of steroids (short course steroids less than 7 days duration, allowable at the discretion of the investigators)
• Experimental medications, vaccines, or biologicals
• Intent to use HIV antiretroviral pre/post-exposure prophylaxis (PrEP or PEP) during the study, outside of the study procedures
