Mean Tmax is defined as the mean of time to reach maximum plasma concentration reported for each subject by cohort.

  4. Mean apparent clearance (CL/F) of Bendavia (ml/hr/kg) in each cohort.

    Time frame: Immediately prior to dosing (0hr) to 48 hours post-dose

    Blood drawn at pre-dose (immediately prior to study drug ingestion), 0.5, 1, 1.5, 2, 2.5, 3, 3.5, 4, 5, 6, 8, 12, 18, 24, 36, and 48 hours post-dose will be assessed for Bendavia plasma concentrations. CL/F will be calculated using validated pharmacokinetic analysis software and mean CL/F for Bendavia is defined as the mean of CL/F reported for each subject by cohort.

  5. Mean Volume of Distribution (Vd/F) of Bendavia (ml/kg) in each cohort.

    Time frame: Immediately prior to dosing (0hr) to 48 hours post-dose
