Abstract/OtherAbstract:
Background Several cancer therapies can prolong cardiac repolarization. This study assessed the potential of eribulin to affect cardiac repolarization in patients with advanced solid tumors. Methods In this Phase I, open-label, single-arm study, patients received eribulin mesylate (1.4 mg/m(2); Days 1 and 8 of a 21-day cycle). The primary objective was to assess the effect of eribulin on the QTcF pre- and post-infusion; QTcF and QTcNi were compared for ability to remove heart-rate dependence of the QT interval. Relationship between concentration of eribulin and ΔQTc was explored using linear mixed-effects analysis. Secondary objectives explored pharmacokinetics, safety, and tolerability. Results Twenty-six patients were enrolled. QTcNi was more effective than QTcF in correcting for heart-rate dependency of the QT interval. On Day 1, mean ΔQTcNi were ~0 at all timepoints. An apparent time-dependent increase in ΔQTc was observed: on Day 8, changes from baseline were larger and more variable, without clear relation to plasma levels of eribulin. Day 8 predose ΔQTcNi was 5 ms, post-infusion mean values ranged from 2 to 9 ms (largest mean ΔQTcNi at 6 h). No new or unexpected toxicities were reported. Conclusion Eribulin demonstrated an acceptable safety profile and a minor prolongation of QTc not expected to be of clinical concern in oncology patients.
