evaluation of trc105 in the treatment of recurrent ovarian, fallopian tube, or primary peritoneal carcinoma

Conditions: Recurrent Ovarian Cancer; Fallopian Tube Carcinoma; Primary Peritoneal Carcinoma

Summary: the purpose of this study is to evaluate the safety and efficacy of trc105 in patients with recurrent epithelial ovarian, fallopian tube, or primary peritoneal carcinoma.

angiogenesis plays a central role in the progression of epithelial ovarian cancer. in mouse models, vegf-inhibitors diminish ovarian tumor growth, metastasis and malignant ascites formation. independent phase 2 trials have demonstrated single-agent activity for bevacizumab in recurrent ovarian cancer, and randomized controlled phase 3 trials are ongoing in the first-line setting (gog 0218 and icon-7) and for recurrent disease (gog 0213, oceans). trc105 is an antibody to cd105, an important non-vegf angiogenic target on vascular endothelial cells. trc105 inhibits angiogenesis, tumor growth and metastases in preclinical models. in a phase 1 study of advanced solid tumors, trc105 therapy caused a global reduction in angiogenic biomarkers and reduced tumor burden at doses that were well-tolerated. we hypothesize that trc105 will have single-agent activity in recurrent ovarian cancer. by targeting a non-vegf pathway, trc105 has the potential to complement vegf inhibitors which could represent a major advance in ovarian cancer therapy.
