abstract
Purpose:
To investigate the combination of liposomal doxorubicin/pazopanib in
advanced relapsed/refractory ovarian cancer.
Patients and Methods: Twenty-two patients received liposomal doxorubicin/pazopanib. Initial doses (liposomal doxorubicin, 40 mg/m2 monthly; pazopanib, 400 mg daily) were too toxic; three subsequent groups received lower doses/altered schedules.
Results: The maximum tolerated doses (MTD) were liposomal doxorubicin, 30 mg/m2, and pazopanib, 400 mg daily. Severe toxicity included neutropenia (18%), rash/desquamation (14%), hypertension (9%), and hand-foot syndrome (9%). Five of the eight patients treated with MTD had grade 3 toxicity during the first two cycles. Dose reductions were frequently required.
Conclusions: Further development of the liposomal doxorubicin/pazopanib combination is not recommended.
