Pharmacokinetics and pharmacodynamics of m-nab-paclitaxel in the KPfC secreted protein acidic and rich in cysteine (SPARC) mouse model. (A) Cohorts of KPfC SPARC+/+ (n=8) and KPC SPARC−/− mice (n=11) were treated with 60 mg/kg m-nab-paclitaxel, and tumour samples were taken 2 h after dosing and analysed by liquid chromatography tandem mass spectrometry (LC-MS/MS). (B) Representative high-resolution ultrasound picture of typical KPfC murine pancreatic tumour. (C) Quantification of tumour volume growth using biweekly three-dimensional high-resolution ultrasound shows no significant decrease in tumour burden on day 7 in KPfC SPARC+/+ versus KPfC SPARC−/− pancreatic tumours following three injections of 60 mg/kg m-nab-paclitaxel over 7 days. (D) Computer-based quantification of apoptosis (cleaved caspase-3) in pancreatic tumours from KPfC SPARC+/+ (n=6) and KPfC SPARC−/− mice (n=5) treated with 60 mg/kg m-nab-paclitaxel. All animals were sacrificed 2 h after the last dose of m-nab-paclitaxel.
