PEREGRINE PROVIDES UPDATE ON HCV CLINICAL PROGRAM
 
-- Preliminary Data from Phase II Study Shows Antiviral Activity and Positive Safety Profile at Both Bavituximab Doses Evaluated; Supporting Further Dosing and Combination Studies --
 
-- Company to Seek Collaboration to Advance HCV Program While Continuing to Focus on its Lead Bavituximab Clinical Program in Multiple Solid Tumor Indications Including Lung Cancer --
 
TUSTIN, CA, December 29, 2011 -- Peregrine Pharmaceuticals, Inc. (NASDAQ: PPHM), a clinical-stage biopharmaceutical company developing first-in-class monoclonal antibodies for the treatment of cancer and viral infections, today provided an update from its randomized Phase II bavituximab study in patients infected with genotype-1 chronic hepatitis C virus (HCV). Patients were randomized in the three-arm study to receive one of two doses of bavituximab (0.3mg/kg or 3mg/kg) or pegylated interferon alpha-2a, in combination with ribavirin. The goals of the study were to determine if bavituximab plus ribavirin has a better safety profile as compared to interferon plus ribavirin, to confirm that the combination of bavituximab and ribavirin has antiviral activity defined as 12 week early virologic response (EVR)1 and to compare antiviral activity of peg-interferon plus ribavirin versus bavituximab plus ribavirin. 
 
A preliminary data analysis indicates that the combination of bavituximab and ribavirin appeared safe and well tolerated with patients reporting fewer side effects than in the interferon-containing arm.  Initial data from the study also indicated that both dose levels of bavituximab with ribavirin demonstrated antiviral activity, however the antiviral effects in patients receiving the 0.3 mg/kg dosing level were more pronounced.  A comparison of the viral data indicated that the kinetics of antiviral activity were different between the interferon and bavituximab treatment groups with a high percentage of those patients achieving EVR in the interferon arm of the study doing so between week 4 and 8 and the majority of patients achieving EVR in the bavituximab groups doing so at the week 12 end of study timepoint.  More patients had achieved EVR in the interferon-containing group by the end of the study, however based on the nature of late EVR development in the bavituximab containing arms at the very end of the 12 week trial, a longer-term evaluation is needed to adequately compare the effectiveness of bavituximab and interferon.  The company plans to present full results from the study at a medical conference in 2012.  

“We are pleased with the initial results we have seen from this clinical study evaluating the combination of bavituximab with an established antiviral drug in HCV patients.  We see good evidence that the combination of bavituximab with ribavirin has a better safety profile than an interferon containing regimen which was one of the primary objectives of the study,” said Joseph S. Shan, vice president of clinical and regulatory affairs at Peregrine Pharmaceuticals.  “In addition, we also see that while both dose levels of bavituximab were active, the lower dose level appears more active in HCV patients than the high dose level. Taken together, these early results are very important in validating that the combination of bavituximab with its immunological mechanism of action with an active antiviral agent has a good safety profile and promising antiviral activity. These results suggest that future studies evaluating longer bavituximab treatment durations at or around the lower dose level in combination with ribavirin and potentially direct acting antivirals in certain patient populations may hold promise as interferon-free HCV therapeutic regimens.”

 
 

 



“The early data from this trial are promising and suggest that continued development of bavituximab in HCV patients is warranted to explore the full immune-modulating potential of the compound in combination with antiviral agents,” said Steven W. King, president and chief executive officer of Peregrine. “With this data in hand, we plan to actively seek development partners interested in working with us to move the PS-targeting antiviral program forward while we continue to focus our resources on the advancement of our bavituximab oncology clinical program in multiple solid tumor indications including non-small cell lung cancer (NSCLC) and pancreatic cancers as well as other indications with high unmet medical need. With as many as six data points coming over the next six months or so from our ongoing phase II trials in front and second line NSCLC and the additional possible data points coming from five additional oncology trials, this is a good time to seek partners for the antiviral program which has shown promise in this study. We look forward to sharing full data from the HCV trial in 2012 and to moving the program forward in the future.”

1. EVR is defined as equal or greater than a 2 log reduction in HCV RNA from baseline.

About the Phase II HCV Trial
In this multicenter Phase II randomized trial, 66 patients with previously untreated genotype-1 chronic HCV infection were randomly assigned to one of three treatment arms. Patients received daily oral ribavirin (1000 mg) with either weekly bavituximab (0.3 mg/kg or 3 mg/kg) or pegylated interferon alpha-2a (180 µg) for up to 12 weeks and were tested for safety parameters and antiviral activity.

 
About Bavituximab's Antiviral Approach
Bavituximab is the first in a new class of patented antibody therapeutics that target and bind to phosphatidylserine (PS), a specific phospholipid component of cell membranes. Bavituximab helps reactivate and direct the body's immune system to destroy infected cells and virus particles that exhibit this specific phospholipid on their surface. Since their target is host-derived rather than pathogen-derived, PS-targeting antibodies have the potential for broad-spectrum antiviral activity and are also expected to be much less susceptible to the viral mutations that often lead to drug resistance.
