Trial Outcomes & Findings for Evaluating Pharmacokinetic Interactions With Vaginal Ring Contraceptives and ART (NCT NCT01903031)

NCT ID: NCT01903031

Last Updated: 2018-06-06

Results Overview

This evaluates the effect of EFV and ATV/r on etonogestrel by measuring etonogestrel concentrations on all three study arms 21 days after NuvaRing administration. The pharmacokinetic (PK) blood sample for measurement of etonogestrel on study day 21 was taken before the NuvaRing was removed. The assay lower limit of quantification for etonogestrel was 250 pg/mL; values \< 250 were assigned a value of half the lower limit (ie, 125 pg/mL).

Timeframe: Intensive RTV PK samples at pre-dose, 1, 3, 4, 5, and 8 hours post-dose on study day 0 (before vaginal ring placement) and on study day 21 (3 weeks after vaginal ring placement)

Population: The analysis population is the 23 A5316 participants enrolled in Arm C (NuvaRing with ATV/r arm plus TDF and one or more NRTIs) eligible for the secondary outcome of RTV PK parameters.

This evaluates the effect of NuvaRing on the PK parameter AUC(0-24h) of RTV before NuvaRing placement (at study day 0) and three weeks later (on study day 21), prior to NuvaRing removal. AUC(0-24h) defines area under the concentration-time curve over the period of 24 hours (pre-dose concentration was used to impute concentration at 24h).
