paragraph: Phase Ib Study of Bavituximab With Carboplatin and Pemetrexed in Chemotherapy-Naive Advanced Nonsquamous Non-Small-Cell Lung Cancer . bavituximab is an immunomodulatory chimeric monoclonal antibody that inhibits phosphatidylserine signaling, which promotes innate and adaptive immune responses. In this phase Ib trial we evaluated the safety, tolerability, and preliminary antitumor activity of pemetrexed, carboplatin, bavituximab in advanced non-small-cell lung cancer (NSCLC). ### Patients And Methods Patients with advanced nonsquamous NSCLC and performance status 0 or 1 were treated with pemetrexed 500 mg/m ### results Between March 29, 2011 and December 30, 2013, 26 patients were enrolled. Three patients each were enrolled into dose escalation cohorts of bavituximab (0.3, 1, and 3 mg/kg). Therapy was well tolerated with no DLTs, and toxicities were consistent with those expected from pemetrexed/carboplatin. Overall response was 28%, with a median progression-free and overall survival of 4.8 months and 12.2 months, respectively. ### conclusion The combination of pemetrexed, carboplatin, bavituximab is well tolerated. However, with toxicities and preliminary efficacy signal similar to pemetrexed/carboplatin alone, further studies of bavituximab should focus on ways to enhance its immunomodulatory role.
