Peregrine Pharma Offers Update for Top-Line Data from Phase II Trial of Bavituximab

Peregrine Pharmaceuticals, Inc.

, today reported data from its randomized, double-blind placebo-controlled Phase II trial of bavituximab in patients with second-line non-small cell lung cancer (NSCLC). Data from the trial has been updated based on completion of an earlier review of discrepancies in the trial and the most current survival data from the trial. Updated results from this Phase II trial indicate a meaningful improvement in median overall survival of 11.7 months in the 3mg/kg bavituximab + docetaxel arm compared to 7.3 months in the control arm (HR=0.73; p value=0.217). Persistent separation in the survival curves was observed with response rates and progression free survival also favoring the 3mg/kg bavituximab + docetaxel arm in this difficult to treat second-line NSCLC. The results also demonstrated that bavituximab was well-tolerated with no significant differences in adverse events between the trial arms. Peregrine plans to report additional data from the trial, including updated subgroup analysis and safety data, at an upcoming scientific meeting. Peregrine's randomized, double-blind, placebo-controlled Phase II trial was designed to evaluate docetaxel with bavituximab or placebo and enrolled 121 patients with previously treated locally advanced or metastatic NSCLC. Patients enrolled in the trial were not selected based on genetic or other biomarkers. All patients had confirmed Stage IIIb or IV non-squamous NSCLC and had progressed following one prior chemotherapy regimen. The trial was designed to evaluate overall response rate (ORR) measured in accordance with RECIST criteria, progression-free survival (PFS), duration of response, overall survival (OS), and safety.
