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.

Outcome Measures
Primary Outcomes (1)
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)
QTcF = QT corrected for Fridericia's formula
Days 1, 2, 5, 6, 19 and 20
Secondary Outcomes (8)
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 dosing
Days 1, 5 and 19
Difference from placebo of Moxifloxacin in change from period-specific baseline in QTcF (ΔΔQTcF) following a single dose
Days 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 categories
Days 1, 5 and 19
Time of maximum observed plasma concentration (Tmax) of EFV
Days 1, 2, 19 and 20
Maximum observed plasma concentration (Cmax) of EFV
Days 1, 2, 19 and 20
- +3 more secondary outcomes
Study Arms (1)
