A Safety and Efficacy Study of Carboplatin, Paclitaxel, Bevacizumab and CA4P in Non-Small Cell Lung Cancer

Summary

The purpose of this study is to determine the safety, tolerability and efficacy of combretastatin A4 phosphate (CA4P), also known as fosbretabulin, in combination with bevacizumab (Avastin), carboplatin and paclitaxel in patients with chemotherapy naïve non-small cell lung cancer (NSCLC). This is a randomized parallel arm study. All participants will receive carboplatin, paclitaxel and bevacizumab, and half will additionally receive CA4P. Patients who complete the first 6 cycles of therapy and have not experienced disease progression will receive maintenance therapy with bevacizumab alone or with bevacizumab plus CA4P. The rationale for this study is the potential additive or synergistic actions of vascular disrupting agents like CA4P with anti-angiogenic agents like bevacizumab.
