Abstract
Purpose
The aim of this study was to determine the plasma pharmacokinetics of eribulin mesylate in patients with solid tumors with mild and moderate hepatic impairment.
Patients and methods
A phase I, pharmacokinetic study was performed in patients with advanced solid tumors and normal hepatic function or Child-Pugh A (mild) or Child-Pugh B (moderate) hepatic impairment. Treatments were given on day 1 and 8 of a 21-day cycle and consisted of 1.4, 1.1 and 0.7 mg/m2 eribulin mesylate, for normal hepatic function, Child-Pugh A and B hepatic impairment, respectively. Also safety and anti-tumor activity were determined.
Results
Hepatic impairment increased exposure to eribulin. In patients with Child-Pugh A (N = 7) and Child-Pugh B (N = 5), mean dose-normalized AUC0–∞ was 1.75-fold (90 % confidence intervals (CI): 1.16–2.65) and 2.48-fold (90 % CI: 1.57–3.92) increased, respectively, compared with patients who have normal function (N = 6). The most frequently reported treatment-related events were alopecia (12/18) and fatigue (7/18) and these were observed across all groups. Nine patients (50 %) had stable disease as best response.
Conclusions
A reduced dose of 1.1 and 0.7 mg/m2 of eribulin mesylate is recommended for patients with Child-Pugh A or B hepatic impairment, respectively.
