Primary Outcome Measures
NameTimeMethod
Number of Participants With Treatment-emergent Adverse Events (AEs) and Serious Adverse Events (SAEs)Baseline up to 150 days after the last administration of study drug

An AE was any untoward medical occurrence in a participant who received study drug 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 drug and up to 150 days after last dose that were absent before treatment or that worsened relative to pretreatment state.

Secondary Outcome Measures
NameTimeMethod
Time to Reach Maximum Observed Plasma Concentration (Tmax) in Cycle 1Cycle 1: 0 (predose), 1, 24 and 72 hours, 7 and 14 days postdose
Time to Reach Maximum Observed Plasma Concentration (Tmax) in Cycle 4Cycle 4: 0 (predose), 1, 24 and 72 hours, 7 and 14 days postdose
Plasma Decay Half-Life (t1/2) in Cycle 1Cycle 1: 0 (predose), 1, 24 and 72 hours, 7 and 14 days postdose

Plasma decay half-life is the time measured for the plasma concentration to decrease by one half.

Systemic Clearance (CL) in Cycle 1Cycle 1: 0 (predose), 1, 24 and 72 hours, 7 and 14 days postdose

CL is a quantitative measure of the rate at which a drug substance is removed from the body.

Plasma Decay Half-Life (t1/2) in Cycle 4Cycle 4: 0 (predose), 1, 24 and 72 hours, 7 and 14 days postdose

Plasma decay half-life is the time measured for the plasma concentration to decrease by one half.

Time to Reach Last Quantifiable Concentration (Tlast) in Cycle 1Cycle 1: 0 (predose), 1, 24 and 72 hours, 7 and 14 days postdose
Maximum Observed Plasma Concentration (Cmax) in Cycle 1Cycle 1: 0 (predose), 1, 24 and 72 hours, 7 and 14 days postdose
Time to Reach Last Quantifiable Concentration (Tlast) in Cycle 4Cycle 4: 0 (predose), 1, 24 and 72 hours, 7 and 14 days postdose
Maximum Observed Plasma Concentration (Cmax) in Cycle 4Cycle 4: 0 (predose), 1, 24 and 72 hours, 7 and 14 days postdose
Concentration at End of Infusion (Cendinf) in Cycle 1Cycle 1: 0 (predose), 1, 24 and 72 hours, 7 and 14 days postdose
Systemic Clearance (CL) in Cycle 4Cycle 4: 0 (predose), 1, 24 and 72 hours, 7 and 14 days postdose

CL is a quantitative measure of the rate at which a drug substance is removed from the body.

Concentration at End of Infusion (Cendinf) in Cycle 4Cycle 4: 0 (predose), 1, 24 and 72 hours, 7 and 14 days postdose
Volume of Distribution (Vz) in Cycle 1Cycle 1: 0 (predose), 1, 24 and 72 hours, 7 and 14 days postdose

Vz is defined as the theoretical volume in which the total amount of drug would need to be uniformly distributed to produce the desired blood concentration of a drug.

Volume of Distribution (Vz) in Cycle 4Cycle 4: 0 (predose), 1, 24 and 72 hours, 7 and 14 days postdose

Vz is defined as the theoretical volume in which the total amount of drug would need to be uniformly distributed to produce the desired blood concentration of a drug.

Volume of Distribution at Steady State (Vss) in Cycle 1Cycle 1: 0 (predose), 1, 24 and 72 hours, 7 and 14 days postdose

Vz is defined as the theoretical volume in which the total amount of drug would need to be uniformly distributed to produce the desired blood concentration of a drug. Vss is the Vz at steady-state.

Volume of Distribution at Steady State (Vss) in Cycle 4Cycle 4: 0 (predose), 1, 24 and 72 hours, 7 and 14 days postdose

Vz is defined as the theoretical volume in which the total amount of drug would need to be uniformly distributed to produce the desired blood concentration of a drug. Vss is the Vz at steady-state.
