Study Summary

The purpose of this study is to determine the safety and tolerability of PA-824 when given with a single dose of midazolam, and to determine whether PA-824 inhibits CYP3A to a clinically important degree as measured by the effect of PA-824 on the pharmacokinetics of midazolam, a known CYP3A substrate.

Primary Outcome

The PK parameters to be calculated for midazolam and 1-hydroxy midazolam include area under the curve \[AUC(0-t) and AUC(0-inf)\], maximum observed concentration (Cmax), time to maximum observed plasma concentration (Tmax), half-life (t1/2), and apparent terminal elimination rate constant (Kel).

Interventions

  • DRUG Midazolam
  • DRUG PA-824
