PR 10-6-11: Enroll. Comp. in Ph.2 Randomized NSCLC/2ndline Bavi+Doce Trial

Peregrine Completes Patient Enrollment in Second-Line Non-Small Cell Lung Cancer Trial; Data to Be Unblinded in First Half 2012
• Third Randomized Phase II Trial Enrolled in Last 30 Days Sets Timeline for Multiple Upcoming Clinical Data Points in 2011 and 2012
http://ir.peregrineinc.com/releasedetail.cfm?ReleaseID=611679

TUSTIN, 10/6/11: Pharmaceuticals, Inc. (NASDAQ: PPHM), a clinical-stage biopharmaceutical company developing first-in-class monoclonal antibodies for the treatment of cancer and viral infections, today announced the completion of enrollment and randomization of 121 patients in a double-blind, placebo-controlled Phase II trial evaluating bavituximab in combination with docetaxel in patients with previously treated locally advanced or metastatic non-small cell lung cancer (NSCLC). Bavituximab is a phosphatidylserine (PS)-targeting monoclonal antibody with broad therapeutic potential also being evaluated in randomized Phase II trials for front-line NSCLC, pancreatic cancer, and hepatitis C virus (HCV) infection as well as in several investigator-sponsored trials (ISTs) in additional oncology indications.

"Completing patient enrollment in 3 randomized Phase II trials over the last month sets the stage for reporting early results from all 3 trials over the coming months. We look forward to evaluating and reporting interim data from an earlier completed randomized Phase II trial in front-line NSCLC and data from an HCV study later this year as we await unblinding data from this second-line NSCLC trial in the first half of next year," said Steven W. King, president and chief executive officer of Peregrine. "In our prior Phase II trials, we have seen encouraging tumor response data, which have correlated with promising survival for patients treated with bavituximab in combination with chemotherapy. This latest trial's rigorous design is intended to determine if bavituximab may improve tumor response rates when given in combination with the commonly used second line chemotherapy treatment docetaxel. Unfortunately treatment with docetaxel alone is expected to result in less than a 6%(1) tumor response rate, but since docetaxel increases exposure of bavituximab's PS target, we believe the combination has a good chance to improve on these results and hopefully improve overall survival for patients who have already failed a prior treatment for this deadly form of cancer. We greatly appreciate the patients and investigators who have participated in our studies and our dedicated team at Peregrine working hard to advance our multiple Phase II trials."

ABOUT PEREGRINE'S TRIAL
Peregrine's randomized, double-blind, placebo-controlled Phase II trial is designed to evaluate docetaxel with bavituximab or placebo and enrolled 121 patients with previously treated locally advanced or metastatic NSCLC. All patients have confirmed Stage IV (TNM Edition 7) non-squamous NSCLC and have progressed following one prior chemotherapy regimen.

Patients were randomized to receive up to 6 cycles of docetaxel with placebo, 1 mg/kg bavituximab, or 3 mg/kg bavituximab until disease progression The primary endpoint of this trial is to compare the objective response rate (ORR) measured in accordance with RESIST criteria. Secondary objectives of the study include progression-free survival (PFS), duration of response, overall survival (OS), and safety. More information about this trial can be found at http://www.clinicaltrials.gov/ct2/show/NCT01138163?term=bavituximab&rank=5 .

ABOUT BAVITUXIMAB
Bavituximab is a first-in-class phosphatidylserine (PS)-targeting monoclonal antibody that represents a new approach to treating cancer. PS is a highly immunosuppressive molecule usually located inside the membrane of healthy cells, but "flips" and becomes exposed on the outside of cells that line tumor blood vessels, creating a specific target for anti-cancer treatments. PS-targeting antibodies target and bind to PS and block this immunosuppressive signal, thereby enabling the immune system to recognize and fight the tumor.

F. Phase IIb Bavi+Doce vs. Refractory NSCLC (randomized, double-blinded, placebo-controlled, n=120, 'registrational')
Protocol: http://clinicaltrials.gov/ct2/show/NCT01138163 (24 U.S. + 15 India + 2 RepGA + 7 RussianFED + 5 Ukraine = 53 as of 8-12-11)
Also listed in: India's CTRI registry ctri.in#2191 (12 sites a/o 3-20-11)
10-6-11: Enrollment complete. http://tinyurl.com/3m9re39
7-14-11/CC: Enrollment was taking longer than expected; have amended protocol; expanding to ~45 sites, expect enroll. comp. "early in Q4/2011", data unblinding 1H'12. http://tinyurl.com/6k6y2as
3-17-10/Roth, CEO S.King: "We refer to this trial as a Registrational Phase II Study, because we believe that if we have results anywhere near approaching what we saw in the earlier [India] study, it could be a conduit for Accelerated Approval."
6-4-10: Ph.2b randomized reg. trial Open for enrollment: http://tinyurl.com/25v22qk
"up to 120 refractory patients at ~30 clinical sites; goal: fully-enroll by mid'11, topline data by y/e'11."
