Primary Outcome Measures:
  • Number of Participants With Treatment-Emergent Adverse Events (AEs) or Serious Adverse Events (SAEs) [ Time Frame: Day 1 up to 10 days after last dose of study medication (up to 11 days) ]
    An AE was any untoward medical occurrence in a participant who received study medication without regard to possibility of causal relationship. An SAE was an AE resulting in any of the following outcomes or deemed significant for any other reason: death; initial or prolonged inpatient hospitalization; life-threatening experience (immediate risk of dying); persistent or significant disability/incapacity; congenital anomaly. Treatment-emergent are events between first dose of study medication and up to 10 days after last dose that were absent before treatment or that worsened relative to pretreatment state.

  • Area Under the Curve From Time Zero to Last Quantifiable Concentration (AUClast) [ Time Frame: 0 (pre-dose), 0.5, 1, 2, 3, 4, 6, 8, 12, 16, 24, 36, 48 hours post-dose ]
    Area under the plasma concentration-time curve from zero to the last measured concentration (AUClast).

  • Maximum Observed Plasma Concentration (Cmax) [ Time Frame: 0 (pre-dose), 0.5, 1, 2, 3, 4, 6, 8, 12, 16, 24, 36, 48 hours post-dose ]
  • Time to Reach Maximum Observed Plasma Concentration (Tmax) [ Time Frame: 0 (pre-dose), 0.5, 1, 2, 3, 4, 6, 8, 12, 16, 24, 36, 48 hours post-dose ]
  • Apparent Oral Clearance (CL/F) [ Time Frame: 0 (pre-dose), 0.5, 1, 2, 3, 4, 6, 8, 12, 16, 24, 36, 48 hours post-dose ]
    Drug clearance is a quantitative measure of the rate at which a drug substance is removed from the blood.

  • Apparent Volume of Distribution (Vz/F) [ Time Frame: 0 (pre-dose), 0.5, 1, 2, 3, 4, 6, 8, 12, 16, 24, 36, 48 hours post-dose ]
    Volume of distribution is defined as the theoretical volume in which the total amount of drug would need to be uniformly distributed to produce the desired plasma concentration of a drug.

  • Plasma Decay Half-Life (t1/2) [ Time Frame: 0 (pre-dose), 0.5, 1, 2, 3, 4, 6, 8, 12, 16, 24, 36, 48 hours post-dose ]
    Plasma decay half-life (t1/2) is the time measured for the plasma concentration to decrease by one half.

  • Area Under the Curve From Time Zero to Extrapolated Infinite Time (AUCinf) [ Time Frame: 0 (pre-dose), 0.5, 1, 2, 3, 4, 6, 8, 12, 16, 24, 36, 48 hours post-dose ]
    AUCinf is the area under the plasma concentration versus time curve from time zero to extrapolated infinite time.
