Study Endpoints
Primary Endpoints
Maximum Observed Plasma Concentration (Cmax) After Administration of AMB Under Fasted Condition
Pre-dose, 0.5, 1, 1.5, 2, 2.5, 4, 8, 12, 18, 24, 36, 48 and 72 hours post-dose

Blood samples were collected at indicated time-points for PK analysis of AMB. PK parameters were calculated by standard non-compartmental analysis. PK Parameter Population included all participants who provided PK parameter data.

Time to Cmax (Tmax) After Administration of AMB Under Fasted Condition
Pre-dose, 0.5, 1, 1.5, 2, 2.5, 4, 8, 12, 18, 24, 36, 48 and 72 hours post-dose

Blood samples were collected at indicated time-points for PK analysis of AMB. PK parameters were calculated by standard non-compartmental analysis.

Time of Last Quantifiable Concentration (Tlast) After Administration of AMB Under Fasted Condition
Pre-dose, 0.5, 1, 1.5, 2, 2.5, 4, 8, 12, 18, 24, 36, 48 and 72 hours post-dose

Blood samples were collected at indicated time-points for PK analysis of AMB. PK parameters were calculated by standard non-compartmental analysis.

Area Under the Plasma Concentration-time Curve From Time Zero Extrapolated to Infinite Time [(AUC(0-inf)] After Administration of AMB Under Fasted Condition
Pre-dose, 0.5, 1, 1.5, 2, 2.5, 4, 8, 12, 18, 24, 36, 48 and 72 hours post-dose

Blood samples were collected at indicated time-points for PK analysis of AMB. PK parameters were calculated by standard non-compartmental analysis.

Area Under the Plasma Concentration-time Curve From Time Zero to Last Time of Quantifiable Concentration [AUC(0-t)] After Administration of AMB Under Fasted Condition
Pre-dose, 0.5, 1, 1.5, 2, 2.5, 4, 8, 12, 18, 24, 36, 48 and 72 hours post-dose

Blood samples were collected at indicated time-points for PK analysis of AMB. PK parameters were calculated by standard non-compartmental analysis.

Apparent Terminal Phase Half-life (t1/2) After Administration of AMB Under Fasted Condition
Pre-dose, 0.5, 1, 1.5, 2, 2.5, 4, 8, 12, 18, 24, 36, 48 and 72 hours post-dose

Blood samples were collected at indicated time-points for PK analysis of AMB. PK parameters were calculated by standard non-compartmental analysis.
