http://ir.peregrineinc.com/releasedetail.cfm?ReleaseID=992804
TUSTIN, Oct. 10, 2016: Peregrine Pharmaceuticals, Inc. (NASDAQ:PPHM/PPHMP), a biopharmaceutical company committed to improving patient lives by manufacturing high quality products for biotechnology and pharmaceutical companies and advancing its proprietary R&D pipeline, today reported that top-line data from the Phase III SUNRISE trial of bavituximab in patients with previously treated locally advanced or metastatic non-squamous non-small cell lung cancer (NSCLC) were presented in an oral presentation at the European Society for Medical Oncology (ESMO) 2016 Congress. The presentation included interim efficacy and safety outcomes, as well as initial findings from the company's ongoing biomarker analysis of samples collected during the study. The SUNRISE Phase III trial was discontinued earlier this year based on a pre-specified interim analysis although patient treatment and follow-up in the study were allowed to continue. The pre-planned biomarker analysis has been taking place as patient follow-up has continued and available results were evaluated as part of the recent top-line data analysis.
The study protocol pre-specified the collection of thousands of patient samples for exploratory analyses over a wide range of possible biomarkers, including pre-treatment levels of beta-2 glycoprotein-1 (B2GP1). Data presented at ESMO demonstrated that patients with pre-treatment B2GP1 levels between 200 and 240 (representing approximately 30% of randomized patients) achieved a statistically significant, 5.5-month improvement (13.2 months vs. 7.7 months) in median overall survival (OS) as compared to patients in the control group with the same range of B2GP1 levels [p = 0.049; hazard ratio (HR) = 0.67]. A similar trend was observed with pre-treatment B2GP1 levels ≥ 200 µg/mL (representing approximately 50% of randomized patients) with 11.9 months vs. 10.1 months median OS in favor of the bavituximab-containing group (p = 0.155; HR = 0.81). Taken together, this strongly suggests B2GP1 levels may be useful for identifying patients who are more likely to benefit from a bavituximab containing therapeutic regimen. Numerous additional biomarkers are currently being analyzed with the goal of developing a multi-marker signature that can potentially identify patients that are likely to receive significant clinical benefit from a bavituximab-containing therapeutic regimen.
Top-line results reported at ESMO today were based on a data cut-off after 70% (330/473) of the targeted OS events had been reached and demonstrated the addition of bavituximab to docetaxel did not result in improvement of the study's primary endpoint of OS in the intent-to-treat population. Median OS for the bavituximab plus docetaxel group was 10.7 months as compared to 10.8 months for the placebo plus docetaxel control group (HR = 1.110; p = 0.382). Median progression free survival (PFS) for the bavituximab-containing group was 4.1 months compared to 3.9 months for the control group (HR = 0.97; p = 0.803). Objective response rates based on independent central review are currently 13% and 11% (p = 0.53) for the bavituximab-containing and control groups, respectively. Additionally, the safety profile of the combination of bavituximab with docetaxel was similar to placebo plus docetaxel.
"With every clinical trial we conduct, we are constantly reminded of the difficulty involved in treating patients with NSCLC. This continues to prove to be a very challenging cancer to combat and the need for effective treatments remains high," David R. Spigel, MD, CSO and Program Director of Lung Cancer Research at the Sarah Cannon Research Institute and one of the lead investigators in the SUNRISE trial. "The findings with regard to B2GP1 that have been collected as part of the ongoing SUNRISE trial data analysis are interesting and support further investigation."
Peregrine intends to further evaluate the role of B2GP1 levels in response to bavituximab therapy in future clinical trials. The company has filed a new patent application directed to the use of this initial biomarker discovery. Additional patient sample testing and analysis is ongoing and may result in other biomarkers of importance.
"We would once again like to thank all of the patients, clinical investigators and scientists who participated in the SUNRISE trial and have made it possible for us to continue to collect and analyze a range of key data from the study. While we were disappointed with the trial being discontinued earlier in the year, we are excited by the fact that we are beginning to learn important information from the trial through the ongoing biomarker analysis program that will be critical in helping guide the future clinical development of bavituximab," said Joseph Shan, VP of Clinical & Regulatory Affairs at Peregrine. "It is encouraging that the initial biomarker analysis has identified an important biomarker early in the process and we are optimistic that additional biomarkers associated with improved outcomes for bavituximab-containing treatments will be identified as the analysis continues. We expect to be able to share the emerging data over the coming months at scientific and medical conferences as the more results become available."
Mr. Shan continued, "It is not uncommon in the cancer field for therapeutic candidates to suffer clinical trial setbacks as researchers continue to learn more about the most appropriate patient populations for those drugs. In this landscape, biomarkers play an increasingly important role in helping identify specific patient characteristics that may impact responses to a treatment. This has been seen historically with targeted cancer treatments, as well as more recently with checkpoint inhibitors including PD-1 inhibitors. We look forward to identifying the equivalent markers for bavituximab that will help guide its clinical development."
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 is believed to override PS mediated immunosuppressive signaling by blocking the engagement of PS with its receptors as well as by sending an alternate immune activating signal. PS targeting antibodies have been shown to shift the functions of immune cells in tumors, resulting in multiple signs of immune activation and anti-tumor immune responses.
Peregrine's clinical development strategy for bavituximab is currently focused on small, early-stage proof-of-concept trials evaluating the drug in combination with other cancer treatments. The intent behind this strategy is to control research and development costs, while continuing to generate clinical data to further validate bavituximab's combination potential that will be critical to bringing onboard a partner to help advance the program.

“Ongoing Biomarker Analysis Has Identified a Biomarker that is Associated with a Statistically Significant Improvement in Overall Survival for Patients Receiving the Bavituximab Combination”
http://ir.peregrineinc.com/releasedetail.cfm?ReleaseID=990296
TUSTIN, Sept. 21, 2016: Peregrine Pharmaceuticals, Inc. (NASDAQ:PPHM/PPHMP), a biopharmaceutical company committed to improving patient lives by manufacturing high quality products for biotechnology and pharmaceutical companies and advancing its proprietary R&D pipeline, today announced that top-line data from the Phase III SUNRISE trial of bavituximab in patients with previously treated locally advanced or metastatic non-squamous non-small cell lung cancer (NSCLC) will be presented as a late-breaking oral presentation at the upcoming European Society for Medical Oncology (ESMO) 2016 Congress. Presented data will include a biomarker in the SUNRISE trial that correlated with a statistically significant improvement in overall survival for patients treated with bavituximab in combination with docetaxel compared to patients treated with docetaxel alone. Peregrine will file a new patent application directed to the use of the biomarker prior to the presentation of results at the ESMO 2016 Congress, which is being held October 7-11, 2016 in Copenhagen, Denmark.
Details of the Phase III SUNRISE trial data presentation are as follows:
Presentation #LBA45
Presentation Title: “Top-line results from SUNRISE: A Phase III Randomized Double-Blind, Placebo-Controlled Multicenter Trial of Bavituximab Plus Docetaxel in Patients with Previously Treated Stage IIIb/IV Non-Squamous NSCLC”
Date: Monday, October 10, 2016 Time: 9:15am (local time in Copenhagen)
"I want to start by thanking the patients, investigators and scientists involved in the SUNRISE trial that have made possible the continuing collection and analysis of important data from the study. While the current interim analysis is still ongoing, it is exciting to already see that a biomarker associated with positive outcomes for patients receiving the combination of bavituximab with docetaxel has been identified. In the evolving cancer therapeutic space, biomarker identification is playing an increasingly critical role in guiding clinical development strategies and trial designs," said Steven W. King, President and CEO of Peregrine. "It is important to note that we are undertaking a broad biomarker analysis effort as part of the SUNRISE trial and this initial set of data is just the first of what we hope will be several findings that will help guide the bavituximab clinical program going forward. We look forward to presenting results from this ongoing analysis effort at the ESMO 2016 Congress, as well as other medical conferences as the additional data becomes available."
The primary goal of the biomarker analysis is to identify a biomarker profile for patients that receive the most benefit from a bavituximab-containing therapeutic regimen. As specified in the study protocol, thousands of patient samples were collected to potentially identify biomarkers associated with improved outcome for patients receiving bavituximab. Peregrine is in the process of filing a new patent application directed to the use of the initial biomarker discovery which will be presented at the ESMO 2016 Congress. Additional patient sample testing and analysis is ongoing and may result in other biomarkers of importance.

9-8-16/CC CEO Steve King: “Topline data from our Phase III SUNRISE trial have been accepted for a late-breaking oral presentation [10-10-16, Dr. David Gerber, UTSW, Lead Author – see below] at the upcoming European Society of Medical Oncology (ESMO) Congress to be held in Copenhagen in early October [Oct7-11]. ESMO is the premier European oncology meeting, attended by thousands of oncologists. The presentation at ESMO will be a great opportunity to share clinical data from the study in conjunction with initial results from ongoing biomarker analysis, which are already highly encouraging. Biomarker analysis was built into the SUNRISE trial from the beginning, including the collection of thousands of patient samples that could be analyzed once of the trial was unblinded. The primary goal the biomarker analysis is to identify a biomarker pattern, present in patients that receive the most benefit from a bavituximab containing therapeutic regimen, and we look forward to sharing the results of the ongoing analysis, with more data expected later in the year. The impact of the effective biomarker identification is already quite evident in oncology drug development, with the latest evidence being PD1/PD-L1 in the development of Keytruda. These types of biomarkers can only be identified through analysis of larger patient populations, such as in the SUNRISE trial. The results of identifying effective biomarkers can potentially have a huge impact on clinical development, potentially reducing the size of future trials, including making possible biomarker-driven clinical designs which could provide even more rapid readouts. Taken together, these developments are setting the stage for new data throughout the rest of 2016 and into 2017.” http://tinyurl.com/jmy77g3
9-8-16/CC: ROBERT GARNICK (Head of Reg. Affairs):
“I’d like to emphasize the strategic importance of the biomarker study, which, as Joe said, was built into the SUNRISE trial. The identification of a positive biomarker or relevant biomarker pattern with clinical efficacy is an important facet of clinical trial design that can be used to inform addl. new studies that in turn might be used to select patients who would best benefit from bavituximab therapy. For example, the identification of the HER2 biomarker was critical in the development of Herceptin. Its importance was only critically established based on the results of a Phase II clinical trial. As Steve previously described, the critical role of the PD-L1 biomarker is emerging as a major factor in the selection of patients for the clinical use of Opdivo & Keytruda. In the case of bavituximab, once a promising biomarker or biomarker pattern is identified, we strategically plan to include these results into potential new clinical trials. I will now turn the call over to Jeff Hutchins, VP of Preclin. Research.” http://tinyurl.com/jydtkoy

Peregrine Pharmaceuticals Provides Update on Oral Presentation of Top-Line Data from Phase III SUNRISE Trial of Bavituximab at European Society for Medical Oncology (ESMO) 2016 Congress
“Ongoing Biomarker Analysis Has Identified a Biomarker that is Associated with a Statistically Significant Improvement in Overall Survival for Patients Receiving the Bavituximab Combination”
http://ir.peregrineinc.com/releasedetail.cfm?ReleaseID=990296
TUSTIN, Sept. 21, 2016: Peregrine Pharmaceuticals, Inc. (NASDAQ:PPHM/PPHMP), a biopharmaceutical company committed to improving patient lives by manufacturing high quality products for biotechnology and pharmaceutical companies and advancing its proprietary R&D pipeline, today announced that top-line data from the Phase III SUNRISE trial of bavituximab in patients with previously treated locally advanced or metastatic non-squamous non-small cell lung cancer (NSCLC) will be presented as a late-breaking oral presentation at the upcoming European Society for Medical Oncology (ESMO) 2016 Congress. Presented data will include a biomarker in the SUNRISE trial that correlated with a statistically significant improvement in overall survival for patients treated with bavituximab in combination with docetaxel compared to patients treated with docetaxel alone. Peregrine will file a new patent application directed to the use of the biomarker prior to the presentation of results at the ESMO 2016 Congress, which is being held October 7-11, 2016 in Copenhagen, Denmark.
Details of the Phase III SUNRISE trial data presentation are as follows:
Presentation #LBA45
Presentation Title: “Top-line results from SUNRISE: A Phase III Randomized Double-Blind, Placebo-Controlled Multicenter Trial of Bavituximab Plus Docetaxel in Patients with Previously Treated Stage IIIb/IV Non-Squamous NSCLC”
Date: Monday, October 10, 2016 Time: 9:15am (local time in Copenhagen)
"I want to start by thanking the patients, investigators and scientists involved in the SUNRISE trial that have made possible the continuing collection and analysis of important data from the study. While the current interim analysis is still ongoing, it is exciting to already see that a biomarker associated with positive outcomes for patients receiving the combination of bavituximab with docetaxel has been identified. In the evolving cancer therapeutic space, biomarker identification is playing an increasingly critical role in guiding clinical development strategies and trial designs," said Steven W. King, President and CEO of Peregrine. "It is important to note that we are undertaking a broad biomarker analysis effort as part of the SUNRISE trial and this initial set of data is just the first of what we hope will be several findings that will help guide the bavituximab clinical program going forward. We look forward to presenting results from this ongoing analysis effort at the ESMO 2016 Congress, as well as other medical conferences as the additional data becomes available."
The primary goal of the biomarker analysis is to identify a biomarker profile for patients that receive the most benefit from a bavituximab-containing therapeutic regimen. As specified in the study protocol, thousands of patient samples were collected to potentially identify biomarkers associated with improved outcome for patients receiving bavituximab. Peregrine is in the process of filing a new patent application directed to the use of the initial biomarker discovery which will be presented at the ESMO 2016 Congress. Additional patient sample testing and analysis is ongoing and may result in other biomarkers of importance.
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 is believed to override PS mediated immunosuppressive signaling by blocking the engagement of PS with its receptors as well as by sending an alternate immune activating signal. PS targeting antibodies have been shown to shift the functions of immune cells in tumors, resulting in multiple signs of immune activation and anti-tumor immune responses.
Peregrine's clinical development strategy for bavituximab is currently focused on small, early-stage proof-of-concept trials evaluating the drug in combination with other cancer treatments. The intent behind this strategy is to control research and development costs, while continuing to generate clinical data to further validate bavituximab's combination potential that will be critical to bringing onboard a partner to help advance the program.

9-8-16/CC CEO Steve King: “Topline data from our Phase III SUNRISE trial have been accepted for a late-breaking oral presentation [10-10-16, Dr. David Gerber, UTSW, Lead Author – see below] at the upcoming European Society of Medical Oncology (ESMO) Congress to be held in Copenhagen in early October [Oct7-11]. ESMO is the premier European oncology meeting, attended by thousands of oncologists. The presentation at ESMO will be a great opportunity to share clinical data from the study in conjunction with initial results from ongoing biomarker analysis, which are already highly encouraging. Biomarker analysis was built into the SUNRISE trial from the beginning, including the collection of thousands of patient samples that could be analyzed once of the trial was unblinded. The primary goal the biomarker analysis is to identify a biomarker pattern, present in patients that receive the most benefit from a bavituximab containing therapeutic regimen, and we look forward to sharing the results of the ongoing analysis, with more data expected later in the year. The impact of the effective biomarker identification is already quite evident in oncology drug development, with the latest evidence being PD1/PD-L1 in the development of Keytruda. These types of biomarkers can only be identified through analysis of larger patient populations, such as in the SUNRISE trial. The results of identifying effective biomarkers can potentially have a huge impact on clinical development, potentially reducing the size of future trials, including making possible biomarker-driven clinical designs which could provide even more rapid readouts. Taken together, these developments are setting the stage for new data throughout the rest of 2016 and into 2017.” http://tinyurl.com/jmy77g3
9-8-16/CC: ROBERT GARNICK (Head of Reg. Affairs):
“I’d like to emphasize the strategic importance of the biomarker study, which, as Joe said, was built into the SUNRISE trial. The identification of a positive biomarker or relevant biomarker pattern with clinical efficacy is an important facet of clinical trial design that can be used to inform addl. new studies that in turn might be used to select patients who would best benefit from bavituximab therapy. For example, the identification of the HER2 biomarker was critical in the development of Herceptin. Its importance was only critically established based on the results of a Phase II clinical trial. As Steve previously described, the critical role of the PD-L1 biomarker is emerging as a major factor in the selection of patients for the clinical use of Opdivo & Keytruda. In the case of bavituximab, once a promising biomarker or biomarker pattern is identified, we strategically plan to include these results into potential new clinical trials. I will now turn the call over to Jeff Hutchins, VP of Preclin. Research.” http://tinyurl.com/jydtkoy
