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.
Detailed description

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| 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 20 | QTcF = QT corrected for Fridericia's formula |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| 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 | — |
| 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 | ECG = Electrocardiogram |
| Trough observed plasma concentration 24 h after a dose (C24) of EFV | Days 1, 2, 19 and 20 | — |
| Area under the concentration-time curve in one dosing interval (AUC(TAU)) of EFV | Days 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 thresholds | Up to 30 days after discontinuation of dose (approximately 52 days) | Serious AE (SAE) |
| Maximum observed plasma concentration (Cmax) of EFV | Days 1, 2, 19 and 20 | — |
