Official title

An Exploratory, Double-Blinded, Randomized, Pharmacokinetic and Safety Study of Three Rectally-Applied Tenofovir 1% Microbicide Gel Formulations

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

This is a double-blinded, randomized, pharmacokinetic and safety study of 3 rectally applied tenofovir microbicide formulations: a vaginal formulation (VF), a reduced glycerin vaginal formulation (RGVF), and a rectal-specific formulation (RF). Nine HIV-negative men will be enrolled. Each participant will receive two inpatient doses of each radiolabeled study product. The first inpatient dose of each product will be administered without coital dynamics simulation (CDS), while the second inpatient dose will be followed by a CDS procedure at 1-hour post dose with instillation of radiolabeled autologous semen. There will be a washout period of at least 11 days between each dose.
