PURPOSE: The objective of this study was to investigate the pharmacokinetic characteristics of pegylated liposomal doxorubicin (PLD) in Chinese female patients with advanced breast cancer by constructing population pharmacokinetic (popPK) models of liposome-encapsulated and free doxorubicin. Additionally, the relationship between pharmacokinetic parameters and drug-related adverse events (AEs) was explored through toxicity correlation analysis.
METHODS: A total of 20 patients with advanced breast cancer were selected from a PLD bioequivalence study. All patients received a single intravenous dose of 50 mg/m2 PLD. Plasma concentrations were measured using liquid chromatography-tandem mass spectrometry (LC-MS/MS). A popPK model was simultaneously built to characterize the pharmacokinetic profiles of liposome-encapsulated and free doxorubicin by non-linear mixed effects model (NONMEM). PLD-related toxicities were graded according to the common terminology criteria for adverse events (CTCAE) v5.0. The Spearman correlation analysis was conducted to explore the relationship between pharmacokinetic parameters and drug-related AEs of both liposome-encapsulated doxorubicin and free doxorubicin.
RESULTS: The concentration-time profiles of both liposome-encapsulated doxorubicin and free doxorubicin were well described by a one-compartment model. The most common AEs to PLD were nausea, vomiting, neutropenia, leukopenia, and stomatitis, most of which were grade I-II. The toxicity correlation analysis results indicated that stomatitis was related to the Cmax of liposome-encapsulated doxorubicin (P < 0.05). No other AEs were found to be correlated with the pharmacokinetic parameters of either free or liposome-encapsulated doxorubicin.
CONCLUSION: A one-compartment model adequately described the popPK characteristics of both liposome-encapsulated and free doxorubicin in Chinese female patients with advanced breast cancer. Most AEs to PLD were mild. Additionally, the occurrence of mucositis may be positively correlated with the Cmax of liposome-encapsulated doxorubicin.
