What was measured

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 serum concentration of a drug. V(ss) = (dose/AUC)\*MRT, where MRT is mean residence time. As per planned analysis, data for this outcome measure was collected and reported dose-wise for each treatment schedule.

Analysis population: PK Analysis Set; Overall number analyzed: participants with data available for analysis.Number analyzed: participants with data available during specified time-point.Given low exposure at 0.01mg/kg dose,there was insufficient data to characterize terminal phase PK required for calculating this parameter.Consequently,this parameter has been marked as "Not Calculated" and therefore not reported for Part 1,Schedule A,0.01mg/kg dose group,in accordance with non-compartmental PK analysis standards.
