Research Excerpts

Overview

NuvaRing releases constant low doses of ethinylestradiol and etonogestrel. NuvaRing is a vaginal contraceptive device that is placed and later removed by the user herself.

AUC 0-infinity was measured using ethinylestradiol serum concentration using a radio-immune assay at several time points during the 21 days of active treatment and the washout period thereafter. AUC 0-infinity was calculated as AUC 0-tlast extrapolated to infinity using the regression line from which t 1/2 was calculated. (NCT01044056)

Pearl Index, by Treatment Group

Primary Efficacy Outcome measure for this study was contraceptive efficacy, or the prevention of in-treatment pregnancy. The total incidence of in-treatment pregnancies was expressed as the Pearl Index, which is defined as the number of in-treatment pregnancies per 100 woman-years of exposure (one woman-year defined as a period of 365.25 days).

"Participants kept diaries to record vaginal bleeding events. They were asked to record, on a daily basis, whether they experienced vaginal bleeding, which included BLEEDING or SPOTTING, at any time during a cycle other than normal menstruation while in the study. (This is also known as breakthough bleeding.) Vaginal bleeding that required >=2 pads/tampons per day was classified as BLEEDING.

RTV PK Parameter Cmin Determined Based on RTV Levels From Individual Participants Enrolled in Arm C

This evaluates the effect of NuvaRing on the PK parameter Cmin of RTV before NuvaRing placement (at study day 0) and three weeks later (on study day 21), prior to NuvaRing removal. Cmin defines minimum concentration observed within the first 8 hours of the 24 hour dosing interval. (NCT01903031)
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)

EFV PK Parameter Maximum Plasma Concentration (Cmax) Determined Based on EFV Levels From Individual Participants Enrolled in Arm B

This evaluates the effect of NuvaRing on the EFV PK parameter Cmax obtained from both sampling periods, before NuvaRing placement (at study day 0) and three weeks later (on study day 21), prior to NuvaRing removal. Cmax defines maximum concentration observed within the first 8 hours of the 24 hour dosing interval. (NCT01903031)
Timeframe: Intensive EFV 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).

EFV PK Parameter Area Under the Concentration-Time Curve (AUC0-24hours) Calculated Based on Intensive EFV PK Samples Obtained From Individual Participants Enrolled in Arm B

This evaluates the effect of NuvaRing on the PK parameter AUC(0-24h) of EFV 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). (NCT01903031)
Timeframe: Intensive EFV 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).

Changes in Insulin-like Growth Factor-1 (IGF-1), IGF Binding Proteins (IGFBP-1, IGFBP-3), and Acid Labile Subunit (ALS)

Changes in serially-sampled fasting serum concentrations of insulin-like growth factor-1 (IGF-1) before and after 49 days of contraceptive therapy. Data were only collected for IGF-1 levels, no assays were performed for IGFBP-1, IGFBP-3, and acid labile subunit (ALS) and no raw data were collected due to insufficient funds. (NCT02367833)
Timeframe: Baseline and post-49 days of contraceptive therapy
