Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The current trial shall clarify the potential of the multitarget antiangiogenic tyrosinkinase inhibitor GW 786034 (pazopanib) in combination with oral cyclophosphamide as salvage treatment in patients with recurrent, pretreated ovarian cancer.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This study is a prospective open-label, non-randomized multicenter phase I/II trial in order to determine overall response rate of patients with platinum-resistant or refractory recurrent, pretreated epithelial ovarian cancer.

In order to assure adequate toxicity assessment, a phase-I-trial is proponed. Phase II will be performed with MTD.
