Despite containing the same cytotoxic agent, different PTX formulations have distinct pharmacological responses and indications in patients with cancer. Several novel PTX delivery vehicles that have shown superior efficacy to Taxol in animal models failed to demonstrate efficacy in Phase II/III human clinical trials. Materials and methods: A 10 mg/kg IV dose of KoEL-paclitaxel or nab-paclitaxel was administered to mice, and the pharmacokinetics (PK) profile of PTX in mice was then compared with the human PK profile from clinical studies. Population PK model and simulation was used to delineate the distribution and elimination characteristics in each species. In addition, tumor shrinkage was measured after weekly administration of both formulations in mouse xenograft model. Results: Our pharmacokinetic modeling results suggested that elimination predominates over distribution in driving PTX disposition in mice, hence restricting the PTX tissue accumulation. Moreover, the rapid elimination of PTX in mice minimized the different formulation effects on PTX tissue distribution, which is believed to link to the superior efficacy of nab-paclitaxel over KoEL-paclitaxel seen in human. In contrast to mice, PTX distribution predominates over elimination in human, and the decline in plasma PTX concentration reflected the deeper tissue distribution by nab-paclitaxel.Conclusion: This species difference in PTX distribution and elimination hinders a simple direct extrapolation from animals to humans. Therefore, species difference in drug distribution and elimination should be carefully assessed during translational drug development.
