Trial Outcomes & Findings for Dolutegravir in Reservoirs (NCT NCT02924389)

NCT ID: NCT02924389

Last Updated: 2022-12-29

Results Overview

Dolutegravir concentrations in blood plasma are assessed as the maximum dolutegravir concentration (Cmax) and 24 hour trough (lowest) concentration (C24h) of dolutegravir in micrograms per milliliter (µg/mL). Blood samples for pharmacokinetics were obtained prior to dosing (hour 0) and 1, 2, 3, 4, 6, 8, and 24 hours after dosing.

PRIMARY outcome

Timeframe: Day 84 (hour 0 through 24)

Population: This analysis includes participants who completed at least one study visit. Fourteen participants completed all study visits and 2 completed a portion of study visits. Males and females are combined for all primary and secondary analyses and are separated only for exploratory study outcomes.

Dolutegravir concentrations in blood plasma are assessed as the maximum dolutegravir concentration (Cmax) and 24 hour trough (lowest) concentration (C24h) of dolutegravir in micrograms per milliliter (µg/mL). Blood samples for pharmacokinetics were obtained prior to dosing (hour 0) and 1, 2, 3, 4, 6, 8, and 24 hours after dosing.

Population: This analysis includes participants who completed at least one study visit. Fourteen participants completed all study visits and 2 completed a portion of study visits. Males and females are combined for all primary and secondary analyses and are separated only for exploratory study outcomes.

Time of maximum dolutegravir concentration is assessed in hours for the time periods of after the first dose and during steady state. Blood samples for pharmacokinetics were obtained prior to dosing (hour 0) and 1, 2, 3, 4, 6, 8, and 24 hours after dosing.

Males and females are combined for all primary and secondary analyses and are separated only for exploratory study outcomes.

The area under the dolutegravir plasma concentration vs time curve in a 24 hour period (AUC24h) is assessed in hours times micrograms per millimeters (h\* µg/mL) for the time periods of after the first dose and during steady state. Blood samples for pharmacokinetics were obtained prior to dosing (hour 0) and 1, 2, 3, 4, 6, 8, and 24 hours after dosing.

SECONDARY outcome

Timeframe: Up to Day 84

Population: Due to lack of viral dynamic decline in PBMCs and inability to measure intracellular dolutegravir consistently with the assays, this secondary outcome could not be assessed.

Dolutegravir concentrations in peripheral blood mononuclear cells required for HIV viral load decline.

SECONDARY outcome

Timeframe: Week 2, Week 6, Week 12

Population: This analysis includes the first 12 study participants; the analysis was not extended to subsequent participants due to study findings being sufficient from the first 12 participants. One participant was removed from this analysis because they had undetectable virus in rectal tissue at the baseline assessment.
