A Phase 2 interventional study of Carotuximab (TRC105) in Recurrent Ovarian Cancer, Fallopian Tube Carcinoma and Primary Peritoneal Carcinoma, sponsored by Tracon Pharmaceuticals Inc.. Completed at 7 sites in United States. Open to participants aged 18 Years and older. Per ClinicalTrials.gov, last updated 2019-03-05.

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.
