Brief summary

The purpose of this study is to determine whether multiple doses of Efavirenz has an effect on the QTc interval (corrected by Fridericia) in CYP2B6 \*1/\*6 and \*6/\*6 healthy subjects.

Design outcomes

Primary

MeasureTime frameDescription
Difference from placebo of Efavirenz (EFV) in change from period-specific baseline in the QT interval corrected for heart rate (HR) via Fridericia's method (QTcF) at postdose extraction times (ΔΔQTcF)Days 1, 2, 5, 6, 19 and 20QTcF = QT corrected for Fridericia's formula

Secondary

MeasureTime frameDescription
Difference from placebo of Moxifloxacin in change from period-specific baseline in QTcF (ΔΔQTcF) following a single doseDays 1, 5 and 19
Number and percent of subjects having a maximum QTcF, HR, PR, and QRS outside of pre-specified categories and those having a maximum ΔQTcF outside of pre-specified categoriesDays 1, 5 and 19
Time of maximum observed plasma concentration (Tmax) of EFVDays 1, 2, 19 and 20
Difference from placebo of EFV in change from period-specific baseline in other ECG parameters: HR, PR, QRS, and uncorrected QT following 14 days of dosingDays 1, 5 and 19ECG = Electrocardiogram
Trough observed plasma concentration 24 h after a dose (C24) of EFVDays 1, 2, 19 and 20
Area under the concentration-time curve in one dosing interval (AUC(TAU)) of EFVDays 1, 2, 19 and 20
Safety based on incidence of AEs, SAEs, AEs leading to discontinuation, marked laboratory abnormalities, findings on 12-lead safety ECG measurements and physical examinations, and abnormalities in vital sign measurements exceeding pre-defined thresholdsUp to 30 days after discontinuation of dose (approximately 52 days)Serious AE (SAE)
Maximum observed plasma concentration (Cmax) of EFVDays 1, 2, 19 and 20
