 This is an open-label study of liposomal doxorubicin with or without volociximab for the treatment of subjects with advanced epithelial ovarian cancer or primary peritoneal cancer relapsed after prior therapy with PlatTaxane-based chemo. Volociximab is an anti-angiogenic integrin inhibitor being developed for the treatment of solid tumors. Preclinical data with a surrogate volociximab antibody administered as monotherapy indicate encouraging efficacy in terms of tumor reduction and anti-angiogenic effects in mouse ovarian cancer xenograft models. In clinical studies, volociximab has been evaluated in several solid tumor types, including pancreatic, renal, and melanoma, with many subjects who entered the studies with progressive disease remaining progression-free for several months.
