Peregrine Pharmaceuticals Reports First Quarter Fiscal Year 2014 Financial Results and Recent Developments

Bavituximab Pivotal Phase III Lung Cancer Trial Named "SUNRISE" on Track for Initiation by Calendar Year-End; Bavituximab Pre-Clinical Proof-Of Concept Studies Underway to Support Potential Immunotherapy Combination Trial; Avid Bioservices Quarterly Revenue Tops $4.5 Million

TUSTIN, CA -- (Marketwired) -- 09/09/13 -- Peregrine Pharmaceuticals, Inc. (NASDAQ: PPHM), a biopharmaceutical company developing first-in-class monoclonal antibodies focused on the treatment and diagnosis of cancer, today announced financial results for the first quarter of fiscal year (FY) 2014 ended July 31, 2013 and provided an update on its advancing clinical pipeline and other corporate developments.

"We continue to steadily progress the bavituximab clinical program as we prepare to initiate a global Phase III trial by year-end in second-line non-small cell lung cancer. In addition to Phase III preparations, our researchers and external collaborators have undertaken a flurry of preclinical experimentation that will help guide exciting new combinations and therapeutic areas for bavituximab. This activity was spurred on by recent data showing that bavituximab works by harnessing the body's natural immune system to fight cancer," said Steven W. King, president and chief executive officer of Peregrine. "Our preclinical development plan is designed to simultaneously look at new indications and therapeutic regimens including new combinations with other immunotherapy agents. Because bavituximab acts on a primary immune system checkpoint, there are an abundance of possible immunotherapy combinations with agents working on further downstream targets. We expect results from these studies over the coming months as we move toward advancing new combinations into the clinic. We look forward to a number of updates on the program as we move through the rest of the year."

BAVITUXIMAB ONCOLOGY PROGRAM HIGHLIGHTS

Lead Indication in Second-Line Non-Small Cell Lung Cancer:

  • Continued to plan for the initiation of the SUNRISE Trial (Stimulating ImmUne RespoNse thRough BavItuximab in a PhaSE III Lung Cancer Study).
    • SUNRISE is a Phase III, global, randomized, double-blind, placebo-controlled clinical trial designed to evaluate the safety, tolerability and efficacy of bavituximab in patients with second-line non-small cell lung cancer (NSCLC). Specifically, the trial will evaluate bavituximab plus docetaxel versus docetaxel plus placebo in approximately 600 patients at clinical sites worldwide. Patients with Stage IIIb/IV non-squamous, NSCLC who have progressed after standard front-line treatment are eligible for enrollment. Patients will be randomized into 1 of 2 treatment arms. All patients will receive up to six 21-day cycles of docetaxel at 75 milligrams per meter squared plus weekly infusions of either bavituximab (3mg/kg) or placebo until progression of toxicity. The primary endpoint of the trial will be overall survival. The company anticipates initiating the SUNRISE trial by the end of this calendar year.

Other Oncology Indications:

The company is exploring the potential of bavituximab through a number of investigator-sponsored trials (IST) including:

  • A Phase I IST evaluating bavituximab in combination with paclitaxel in up to 14 patients with HER2-negative metastatic breast cancer. All patients have been enrolled in this trial with interim data on 13 evaluable patients presented at the 2013 American Society of Clinical Oncology (ASCO) Annual Meeting showing that 85% of patients achieved an objective tumor response, including 15% of patients achieving a complete response measured in accordance with RECIST criteria.

  • A Phase I/II IST evaluating bavituximab in combination with sorafenib in up to 48 patients with advanced hepatocellular carcinoma (liver cancer). The Phase I portion of the trial has completed patient enrollment with enrollment in the Phase II portion of the trial ongoing.

  • A Phase Ib IST evaluating bavituximab in combination with carboplatin and pemetrexed in up to 25 patients with previously untreated Stage IV NSCLC. This trial continues to enroll and dose patients.

  • A Phase I IST evaluating bavituximab in combination with capecitabine and radiation therapy in up to 18 patients with Stage II or III rectal adenocarcinoma. This trial continues to enroll and dose patients.

BAVITUXIMAB IMMUNOTHERAPY DEVELOPMENT PROGRAM

This morning, Peregrine announced the publication of a data supporting the immune-stimulatory mechanism of action of phosphatidylserine (PS)-targeting antibodies, such as the company's lead drug candidate bavituximab in the American Association for Cancer Research (AACR) peer-reviewed journal, Cancer Immunology Research. In the manuscript titled: "Phosphatidylserine-targeting antibody induces M1 macrophage polarization and promotes myeloid derived suppressor cell differentiation," researchers demonstrated that exposed PS plays a major role in the inhibition of pro-inflammatory cellular and cytokine responses in tumors and that PS-targeting antibodies override this primary upstream immune checkpoint, activating multiple downstream immunostimulatory effects, including the conversion of myeloid derived suppressor cells into tumor immunity promoting M1 macrophages and the generation of tumor killing cytotoxic T-cells.

Peregrine is exploring the potential to combine bavituximab with other immunotherapies such as anti-CTLA-4, anti-PD-1, and anti-PD-L1 antibodies and has initiated several ongoing pre-clinical proof-of-concept studies to support an immunotherapy combination trial with bavituximab.

IMAGING PROGRAM HIGHLIGHTS

PS-Targeting Molecular Imaging Program

Peregrine continues to enroll and dose patients in an open-label, single-center trial of its experimental PS-targeting molecular imaging candidate, 124I-PGN650, in patients with various solid tumor types. The primary goal of the trial is to estimate radiation dosimetry in critical and non-critical organs. Secondary objectives of the trial are tumor imaging and safety.

FINANCIAL RESULTS

"Our wholly-owned contract manufacturing subsidiary, Avid Bioservices, continue to perform well, generating over $4.5 million in contract manufacturing revenue in the first quarter of FY 2014, a non-dilutive source of capital. With our current backlog for services, we expect contract manufacturing revenue for the entire FY 2014 to be between $18 and $22 million," said Paul Lytle, chief financial officer of Peregrine. "We also remained focused on seeking potential partners for our bavituximab program while successfully maintaining a balanced financial approach that provides us much flexibility in our ongoing partnering discussions."

Total revenues for the first quarter of FY 2014 were $4,688,000, compared to $4,251,000 for the same quarter of the prior fiscal year. The increase was primarily attributed to an increase in contract manufacturing revenue generated from Avid Bioservices due to an increase in the number of completed manufacturing runs.

Contract manufacturing revenues from Avid's clinical and commercial biomanufacturing services provided to its third-party clients for the first quarter FY 2014 were $4,581,000, compared to $4,135,000 for the same quarter of the prior fiscal year. Peregrine expects contract manufacturing revenues for FY 2014 to be between $18 million and $22 million. In addition to providing biomanufacturing services to its third-party clients, Avid will continue to utilize available capacity and resources to continue its preparation for later stage clinical development and potential commercialization of bavituximab and Cotara.

Total costs and expenses in the first quarter of FY 2014 were $12,308,000, compared to $11,922,000 in the first quarter of FY 2013. This increase was attributable to the current year three-month period increase in the cost of contract manufacturing associated with higher revenues in the current quarter combined with an increase in selling, general and administrative expenses. The increase in selling, general and administrative expenses for the first quarter FY 2014 compared to the first quarter of FY 2013 was primarily attributable to increases in share-based compensation expense, payroll and related expenses, and corporate legal fees.

Peregrine's consolidated net loss was $7,600,000, or $0.05 per share, for the first quarter of FY 2014, compared to a net loss of $7,664,000, or $0.07 per share, for the same quarter of the prior year.

Peregrine reported $41,600,000 in cash and cash equivalents as of July 31, 2013, compared to $35,204,000 at fiscal year ended April 30, 2013.

More detailed financial information and analysis may be found in Peregrine's Annual Report on Form 10-Q, which will be filed with the Securities and Exchange Commission today.
