Abraxane is just another form of paclitaxel. Not a threat to Bavituximab. It might work as a combination with carboplatin and Bavi in first-line NSCLC. http://en.wikipedia.org/wiki/Abraxane Here is the report on the phase 3 of Abraxene with carboplatin in first-line NSCLC. It did not improve OS significantly over regular paclitaxel (solvent based). http://www.ncbi.nlm.nih.gov/pubmed/22547591 J Clin Oncol. 2012 Jun 10;30(17):2055-62. doi: 10.1200/JCO.2011.39.5848.

Abstract PURPOSE: This phase III trial compared the efficacy and safety of albumin-bound paclitaxel (nab-paclitaxel) plus carboplatin with solvent-based paclitaxel (sb-paclitaxel) plus carboplatin in advanced non-small-cell lung cancer (NSCLC).
PATIENTS AND METHODS: In all, 1,052 untreated patients with stage IIIB to IV NSCLC were randomly assigned 1:1 to receive 100 mg/m(2) nab-paclitaxel weekly and carboplatin at area under the concentration-time curve (AUC) 6 once every 3 weeks (nab-PC) or 200 mg/m(2) sb-paclitaxel plus carboplatin AUC 6 once every 3 weeks (sb-PC). The primary end point was objective overall response rate (ORR).
RESULTS: On the basis of independent assessment, nab-PC demonstrated a significantly higher ORR than sb-PC (33% v 25%; response rate ratio, 1.313; 95% CI, 1.082 to 1.593; P = .005) and in patients with squamous histology (41% v 24%; response rate ratio, 1.680; 95% CI, 1.271 to 2.221; P < .001). nab-PC was as effective as sb-PC in patients with nonsquamous histology (ORR, 26% v 25%; P = .808). There was an approximately 10% improvement in progression-free survival (median, 6.3 v 5.8 months; hazard ratio [HR], 0.902; 95% CI, 0.767 to 1.060; P = .214) and overall survival (OS; median, 12.1 v 11.2 months; HR, 0.922; 95% CI, 0.797 to 1.066; P = .271) in the nab-PC arm versus the sb-PC arm, respectively. Patients = 70 years old and those enrolled in North America showed a significantly increased OS with nab-PC versus sb-PC. Significantly less grade = 3 neuropathy, neutropenia, arthralgia, and myalgia occurred in the nab-PC arm, and less thrombocytopenia and anemia occurred in the sb-PC arm.
CONCLUSION: The administration of nab-PC as first-line therapy in patients with advanced NSCLC was efficacious and resulted in a significantly improved ORR versus sb-PC, achieving the primary end point. nab-PC produced less neuropathy than sb-PC.
