Design outcomes

Primary

MeasureTime frame
Pharmacokinetics (PK): Maximum Observed Plasma Drug Concentration (Cmax) of EE and LNGPredose up to 72 Hours Post Dose
PK: Area Under the Plasma Concentration-Time Curve from Time 0 up to Time t (AUC0-t), Where t is the Last Time Point at which the Concentration is Above the Lower Limit of Quantification, of EE and LNGPredose up to 72 Hours Post Dose
PK: AUC from Time 0 to Infinity (AUC0-∞) of EE and LNGPredose up to 72 Hours Post Dose

Secondary

MeasureTime frame
PK: Apparent Systemic Clearance (CL/F) of EE and LNGPredose up to 72 Hours Post Dose
PK: Apparent Volume of Distribution Associated with the Terminal Phase (Vz/F) of EE and LNGPredose up to 72 Hours Post Dose
PK: Time to Maximum Observed Plasma Concentration (Tmax) of EE and LNGPredose up to 72 Hours Post Dose
PK: Terminal Elimination Phase Half-Life (t1/2) of EE and LNGPredose up to 72 Hours Post Dose
Safety: Number of Participants with Treatment-Emergent Adverse Events (TEAEs) and Serious Adverse Events (SAEs)Baseline through Day 35
Safety: Number of Participants with Clinically Significant Change from Baseline in Clinical Laboratory ParametersBaseline through Day 21
Safety: Number of Participants with Clinically Significant Change from Baseline in Vital SignsBaseline through Day 21
