Hide Description 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 blood concentration of a drug. Vss is the apparent volume of distribution at steady-state which is estimated by (D/AUC[0-inf]) X (AUMC[0-inf])/AUC[0-inf]) where D is the dose of study drug, AUMC(0-inf) is the area under the first moment curve extrapolated to infinity and AUC(0-inf) is the area under the plasma concentration-time curve from time zero to infinite time. The Vss of paclitaxel (65 mg/m2 and 80 mg/m2) is observed in Cycle 1 (in the absence of T-DM1) and Cycle 2 (in the presence of T-DM1).
