10-15-15: AstraZeneca and Peregrine Pharmaceuticals Expand Ongoing Immuno-Oncology Collaboration to Include Phase II Lung Cancer Combination Clinical Trial
Global, Randomized Phase II Trial to Evaluate Immunotherapy Combination of Peregrine's PS-Targeting Bavituximab and AstraZeneca's PD-L1 Inhibitor Durvalumab (MEDI4736) in Previously Treated NSCLC
http://ir.peregrineinc.com/releasedetail.cfm?ReleaseID=936766
TUSTIN, Oct. 15, 2015: Peregrine Pharmaceuticals, Inc. (NASDAQ:PPHM/PPHMP), a biopharmaceutical company focused on developing therapeutics to stimulate the body's immune system to fight cancer, today announced that it has expanded its ongoing cancer immunotherapy clinical collaboration with AstraZeneca to include a second, later-stage trial. The companies will now also evaluate the immunotherapy combination of Peregrine's phosphatidylserine (PS)-targeted immune-activator, bavituximab, and AstraZeneca's anti-PD-L1 immune checkpoint inhibitor, durvalumab (MEDI4736), in a global Phase II study in patients with previously treated squamous or non-squamous non-small cell lung cancer (NSCLC). The randomized Phase II trial will be conducted by Peregrine.
As part of the Phase II bavituximab and durvalumab combination trial, patients will be evaluated retrospectively for the correlation between their PD-L1 levels and clinical outcomes. This new study builds on the non-exclusive collaboration initiated between the companies in August 2015 [8-24-15: http://tinyurl.com/owlxpsf ] to conduct a Phase I/Ib basket clinical trial evaluating the combination of bavituximab and durvalumab with chemotherapy in multiple solid tumors.
Bavituximab and durvalumab are investigational immunotherapies with different mechanisms that assist the body's immune system in fighting cancer. Bavituximab targets and modulates the activity of phosphatidylserine, a highly immune-suppressive molecule expressed broadly on the surface of cells in the tumor microenvironment. In pre-clinical and translational clinical studies, the treatment increases activated T-cells in tumors and fights cancer by reversing the immunosuppressive environment that many tumors establish in order to proliferate. Durvalumab is a monoclonal antibody directed against programmed cell death ligand 1 (PD-L1). Signals from PD-L1 help tumors avoid detection by the immune system. Preclinical data have demonstrated that combining the enhanced T-cell mediated anti-tumor activity of bavituximab with checkpoint inhibitors, like PD-L1 antibodies, prolong the ability of tumor-specific T-cells to continue attacking the tumor.
"In the short period of time that we have been working with AstraZeneca, we have been very impressed with the company's commitment to innovative translational efforts that will help us better understand the dynamics of tumor immunity and clinical response to durvalumab and bavituximab combination in a range of cancers," said Joseph Shan, MPH, VP, Clinical and Regulatory Affairs of Peregrine. "We expect this extension of our collaboration with AstraZeneca will allow us to run a much more cost-effective and time-efficient trial than would have been possible under our previously planned study using Opdivo as the combination drug in the same lung cancer population. This Phase II study offers several key advantages including a supply of durvalumab that will enable us to conduct a global trial that can enroll patients more rapidly. In addition, the expanded collaboration provides for a more cohesive clinical program utilizing the same PD-L1 and other biomarker analysis across both the new Phase II trial and the already planned Phase I/Ib study combining durvalumab and bavituximab in multiple indications."
ABOUT BAVITUXIMAB: A TARGETED INVESTIGATIONAL IMMUNOTHERAPY
Bavituximab is an investigational chimeric monoclonal antibody that targets phosphatidylserine (PS). Signals from PS inhibit the ability of immune cells to recognize and fight tumors. Bavituximab, the lead compound in Peregrine's immuno-oncology development program, blocks PS to remove this immunosuppressive signal and sends an alternate immune activating signal. Targeting PS with bavituximab has been shown to shift the functions of immune cells in tumors, resulting in robust anti-tumor immune responses.
ABOUT DURVALUMAB (MEDI4736)
Durvalumab is an investigational human monoclonal antibody directed against programmed cell death ligand 1 (PD-L1). Signals from PD-L1 help tumors avoid detection by the immune system. Durvalumab blocks these signals, countering the tumor's immune-evading tactics. Durvalumab is being developed, alongside other immunotherapies, to empower the patient's immune system and attack the cancer.
ABOUT PEREGRINE PHARMACEUTICALS, INC.
Peregrine Pharmaceuticals, Inc. is a biopharmaceutical company with a pipeline of novel drug candidates in clinical trials focused on the treatment of cancer. The company's lead immunotherapy candidate, bavituximab, is in Phase III development for the treatment of second-line non-small lung cancer (the "SUNRISE trial") along with several investigator-sponsored trials evaluating other treatment combinations and additional oncology indications.

8-24-15: AstraZeneca and Peregrine Pharmaceuticals to Collaborate on Immuno-Oncology Combination Clinical Trial
• Collaboration to Focus on Cancer Immunotherapy Combination of Peregrine's PS-Targeting Bavituximab and AstraZeneca's PD-L1 Inhibitor MEDI4736
http://ir.peregrineinc.com/releasedetail.cfm?ReleaseID=928488
TUSTIN, Aug. 24, 2015: AstraZeneca (NYSE:AZN) and Peregrine Pharmaceuticals, Inc. (NASDAQ:PPHM/PPHMP), a biopharmaceutical company focused on developing therapeutics to stimulate the body's immune system to fight cancer, today announced that they have entered into a cancer immunotherapy clinical trial collaboration. The collaboration will evaluate Peregrine's investigational phosphatidylserine (PS)-signaling pathway inhibitor, bavituximab, in combination with AstraZeneca's investigational anti-PD-L1 immune checkpoint inhibitor, durvalumab (MEDI4736). The planned Phase I/Ib trial will evaluate the safety and efficacy of bavituximab in combination with durvalumab in multiple solid tumors.
Peregrine and AstraZeneca will collaborate on a non-exclusive basis, to evaluate the combination of bavituximab and durvalumab with chemotherapy as a potential treatment in various solid tumors. The Phase I part of the trial is expected to establish a recommended dose regimen for the combination and the Phase Ib part of the trial will assess the safety and efficacy of the investigational combination. Under the terms of the agreement, the initial trial will be conducted by Peregrine.
Robert Iannone, Head of Immuno-Oncology, Global Medicines Development, at AstraZeneca said, "We believe that combination therapy in immuno-oncology has the potential to be a novel and highly effective approach to treating cancer. Our partnership with Peregrine provides the opportunity to explore an exciting, novel combination that could deliver important clinical benefit to patients across a range of cancers."

SCIENCE: "Evolution has favored pathogenesis that resembles apoptosis."
Dr. Judah Folkman: ”This [Thorpe’s VTA research] is very promising and very elegant work... The whole goal is really 2-part, reducing the harsh side effects of cancer treatment, and reducing the chance that some cancer cells will evade treatment. That would be a big step in the next decade, and anti-vascular therapy will play a major role." (’97 & ’02 http://tinyurl.com/k5qe96g & http://tinyurl.com/n6vh9hp )
