Improved Progression-Free Survival among Women with Measurable Recurrent Ovarian Carcinoma Treated with CA4P Plus Bevacizumab: A Post-Hoc Analysis of GOG-0186I
FOCUS Study: Physician’s Choice Chemotherapy (PCC) Plus Bevacizumab and CA4P Versus PCC Plus Bevacizumab and Placebo in Platinum-Resistant Ovarian Cancer (prOC)
The first poster presentation highlighted data from post-hoc analyses from the GOG-0186I Study in patients with measurable disease. Study GOG-0186I evaluated the addition of CA4P to treatment with bevacizumab in patients with recurrent ovarian cancer. In the intent-to-treat population, as well as in a subgroup of patients with measurable disease, the addition of CA4P improved progression-free survival (PFS), including improvements in PFS of 6.2 months for patients with larger tumors. The second poster described the design of the company’s on-going FOCUS Study.

"We believe these highly positive data generated for CA4P in combination with anti-angiogenic agents demonstrate the potential for CA4P to alter the treatment landscape for ovarian cancer, and they provide us with confidence as we move our program forward," stated William D. Schwieterman, M.D., President and Chief Executive Officer of Mateon. "Our clinical investigators are excited to participate in the FOCUS Study, a phase 2/3 trial we initiated in June 2016, and we share their excitement as we look forward to the availability of key data from this study in the second half of 2017."
