Trial Outcomes & Findings for Body Compartment Pharmacokinetics of Anti-retroviral Agents That May be Considered for Future On-demand Peri-exposure HIV Prophylaxis Regimens (NCT NCT03976752)

NCT ID: NCT03976752

Last Updated: 2021-08-13

Results Overview

Median drug concentrations of the TFV component of Genvoya were determined at baseline and at each of the protocol specified follow-up time points. Concentrations below the limit of quantification (LOQ) are assigned a value of zero.

Participant Flow

Participants were recruited from the Hope Clinic in Atlanta, Georgia, USA. Participant enrollment began on March 13, 2019 and all follow up was completed September 20, 2019.

After the completion of enrollment in the Pre-drug arm, enrollment began sequentially in Arm A, followed by Arm B and Arm C. Arms A, B, and C were further broken down into two different sub-groups, determining the timing of the rectal swab and biopsy procedure. Arm D was enrolled last and included a single time point specimen collection. Participants were able to take part in more than one study arm, with at least a 6 week period after completion of one study arm before beginning another one.

Participant milestones
Measure
Pre-drug
Participants enrolled in the pre-drug arm will not receive any drug. At visit 2, they will undergo blood, urine, penile swab, cheek swab, rectal swab and rectal biopsy collection.
Genvoya
Genvoya is a fixed-dose combination anti-retroviral drug containing tenofovir alafenamide (TAF), emtricitabine (FTC), elvitegravir (EVG), and cobicistat. At the second study visit, participants will be provided with a single dose of Genvoya, and instructed to take the dose at home with documentation by digital, time-stamped photo or video. At the third study visit, which will occur 24 hours after home dosing, participants will be given another single dose of Genvoya at the clinic. Participants took Genvoya and had specimens collected at different time points. * Arm A: specimen collection occurred 2 hours and after taking the medication in the clinic (visit 4), and 48 hours after taking the medication in the clinic (visit 5) * Arm B: specimen collection occurred 4 hours and after taking the medication in the clinic (visit 4), and 72 hours after taking the medication in the clinic (visit 5) * Arm C: specimen collection occurred 24 hours and after taking the medication in the clinic (visit 4), and 96 hours after taking the medication in the clinic (visit 5) * Arm D: specimen collection occurred 8 hours after taking the medication in the clinic (visit 4), for a single time point of specimen collection

OTHER_PRE_SPECIFIED outcome

Timeframe: Baseline, and 2, 4, 8, 24, 48, 72, 96 hours after taking the second dose of medication

Population: Data are reported per intervention, based on the time points of sample collection for each study arm (two participants were in multiple study arms). Analysis of drug concentrations in participants in the Pre-drug arm was not performed as no drugs were administered to this study arm.

Median drug concentrations of TFV-DP in rectal tissue were determined at baseline and at each of the protocol specified follow-up time points. Concentrations below the limit of quantification (LOQ) are assigned a value of zero.
