Fate Therapeutics and Regents of the University of Minnesota Enter Into Research Collaboration for Translation of Natural Killer Cell Cancer Immunotherapies

On July 14, 2015 Fate Therapeutics, Inc. reported that it has entered into a research collaboration with Regents of the University of Minnesota for the development of natural killer (NK) cell-based cancer immunotherapeutics (Press release, Fate Therapeutics, JUL 14, 2015, View Source [SID1234516709]). The collaboration will foster the advancement of two distinct therapeutic programs, both of which aim to leverage the inherent ability of NK cells to rapidly detect and effectively destroy malignant cells without prior antigen exposure or administration of a patient’s own immune cells. While adoptive transfer of NK cells has demonstrated anti-tumor activity, the isolation and generation of clinically-relevant quantities of homogeneous populations of highly-persistent NK cells has been challenging. Fate Therapeutics will utilize its cell programming approach and proprietary induced pluripotent stem cell technology under the collaboration to pursue the development of optimized "off-the-shelf" NK cell-based cancer therapeutics.

"Cell-based immunotherapies are rapidly emerging as one of the most promising treatment paradigms for many oncology indications, and NK cell-based therapeutics in particular may offer a compelling off-the-shelf therapeutic approach to adoptive cancer immunotherapy," said Christian Weyer, M.D., M.A.S., President and Chief Executive Officer of Fate Therapeutics. "The University of Minnesota has pioneered the basic research and clinical investigation of NK cell-based therapeutics, and we look forward to collaborating with their expert team in the development of NK cell-based immunotherapies that may provide distinct advantages in transforming the treatment of cancer."

The antibody-dependent cellular cytotoxicity program will be led by renowned NK cell biologist Jeffrey S. Miller, M.D., Deputy Director of the Masonic Cancer Center and the Deputy Director of the Clinical and Translational Science Institute at the University of Minnesota. Dr. Miller and his team have recently identified an "adaptive" NK cell phenotype that exhibits a unique metabolic program shown in preclinical studies to promote long-term persistence in vivo, and that has an epigenetic profile similar to that of cytotoxic T lymphocytes, which may induce potent anti-tumor activity against a variety of tumors. Under the collaboration, Dr. Miller and Fate Therapeutics will apply the Company’s cell programming approach with the intent to optimize NK cell persistence and cytotoxicity and accelerate the development of a programmed "adaptive" NK cellular therapeutic for use in combination with tumor-specific monoclonal antibodies.

"We are excited about the prospects of utilizing cell programming to optimize the anti-tumor properties of the phenotype, and look forward to collaborating with Fate Therapeutics in the development of programmed adaptive NK cell-based immunotherapeutics to treat cancer," said Dr. Miller. "Our data demonstrate that the adaptive phenotype is functionally distinct from conventional NK cells upon triggering through the CD16 receptor, which may make these cells ideal effectors to elicit an enhanced antibody-mediated cytotoxic effect."

The second program, focusing on induced pluripotent stem cell (iPSC)-derived targeted cancer immunotherapy, will be led by Dan Kaufman, M.D., Ph.D., Professor of Medicine and a member of the Masonic Cancer Center at the University of Minnesota. Dr. Kaufman has pioneered the derivation of NK cells from pluripotent stem cells (iNK cells), including the establishment of a clinically-compatible culture system and differentiation protocol that enable the efficient generation of large quantities of cytotoxic NK cells. Leveraging the Company’s proprietary iPSC technology, Dr. Kaufman and Fate Therapeutics will genetically-modify iPSCs to express tumor cell-targeting modalities, creating an immune-engineered pluripotent cell source for use in the derivation of "off-the-shelf" NK cell-based targeted immunotherapies.

"The introduction of antigen-specificity by genetically engineering induced pluripotent stem cells, combined with the unlimited proliferative potential and differentiation capacity of such cells, may prove to be the cornerstone of off-the-shelf targeted cancer immunotherapy," said Dr. Kaufman. "We look forward to developing engineered iNK cell-based cancer therapeutics in collaboration with Fate Therapeutics that may overcome key limitations of adaptive autologous cell therapy including the requirement to isolate and engineer cells for each individual patient."

In consideration for funding the collaboration activities, Fate Therapeutics has the option to secure exclusive patent rights to all intellectual property arising under the collaboration. Additionally, Fate Therapeutics has secured an exclusive option to certain background intellectual property of the University of Minnesota. Drs. Miller and Kaufman will serve as advisors to the Company in the development of hematopoietic cell-based immunotherapies, including those derived from induced pluripotent stem cells.

Highlights Since January 31, 2015:
"During the fourth quarter, Peregrine achieved multiple milestones spanning all areas of the business. Most importantly, we remain on schedule to complete patient enrollment in the SUNRISE Phase III trial in NSCLC by the end of calendar year 2015, while also planning for the initiation of two new trials designed to further expand our breast and non-small cell lung cancer clinical programs," said Steven W. King, president and chief executive officer of Peregrine. "Our promising new collaboration with Memorial Sloan Kettering Cancer Center , together with the considerable amount of pre-clinical and clinical data that has been generated recently, serves to further validate bavituximab and its potential to enhance the effects of chemotherapy, as well as immune checkpoint targeting treatments. Today, we are more confident than ever in bavituximab and we are strategically expanding our clinical programs to capture the value that we believe exists in new therapeutic combinations and indications. Specifically, we are expanding our NSCLC clinical program to include a planned Phase II study combining bavituximab with Opdivo, an FDA-approved PD-1 inhibitor, while also initiating a planned Phase II/III clinical trial in breast cancer combining bavituximab with chemotherapy. In addition to our drug development efforts, Avid achieved record revenue during this fiscal year 2015 and is on track to grow its revenue in FY 2016 based on the growing backlog of services and the near-term launch of the new manufacturing facility. We look forward to providing updates on our bavituximab clinical program, data from currently enrolling clinical trials and collaborative development efforts in the coming months."

Clinical Highlights:
Continued progress enrolling ongoing SUNRISE clinical trial in non-small cell lung cancer (NSCLC); study remains on schedule to complete enrollment by end of calendar 2015

Peregrine announced plans to expand the bavituximab clinical development program to include a Phase II trial to evaluate the combination of bavituximab and Opdivo (nivolumab), an anti-PD-1 antibody, in NSCLC, and a Phase II/III trial to evaluate bavituximab with chemotherapy combinations in HER2-negative metastatic breast cancer. These trials are expected to be initiated during the second half of 2015.

Phase I study results from an investigator-sponsored trial evaluating bavituximab plus paclitaxel in patients with HER2-negative metastatic breast cancer were published in the peer-reviewed journal, Cancer Medicine. Findings showed that the combination produced an objective tumor response in 85% of evaluable patients, with 15% of patients achieving a complete response, measured in accordance with published Response Evaluation Criteria In Solid Tumors (RECIST).

Data presented at the 2015 ASCO (Free ASCO Whitepaper) annual meeting from a Phase I/II study of bavituximab and sorafenib in advanced hepatocellular carcinoma (HCC) demonstrated that the treatment combination induced multiple signs of immune activation with a corresponding reduction of T-regulatory cells in the tumor environment. The treatment was well-tolerated with no indications of autoimmune adverse events that have been seen with other checkpoint immunotherapies.

Preclinical Highlights:
Peregrine and Memorial Sloan Kettering Cancer Center entered into a research agreement to explore the potential of Peregrine’s proprietary PS-targeting antibody platform. The goal of the research is to identify effective treatments combining bavituximab with other checkpoint inhibitors or immune stimulating agents.

Data from preclinical studies presented at the 2015 ASCO (Free ASCO Whitepaper) annual meeting demonstrated the ability of the company’s PS-targeting antibodies to significantly increase the prevalence of tumor infiltrating CD8+ T-cells and immune-activating cytokines, while decreasing tumor-promoting macrophages and myeloid cells. These findings highlight the ability of the antibodies to enhance the anti-tumor effects of both chemotherapy and immune checkpoint inhibitors.

Two preclinical abstracts and one clinical translation abstract were presented at the 106th Annual Meeting of the American Association for Cancer Research (AACR) (Free AACR Whitepaper). Most notably, initial data from a pilot study of clinical translational ex vivo cultures show that bavituximab, both alone and with docetaxel, elicits evidence of a tumor-specific immune response in patients with human adenocarcinoma of the lung including tumors with low PD-L1 expression.

Preclinical data presented at the Keystone Tumor Immunology Symposium showed that a phosphatidylserine (PS)-targeting antibody equivalent to bavituximab combined with an anti-PD-1 antibody displayed statistically significant increases in tumor fighting immune cells, activation signals and inflammatory cytokines in a model of melanoma compared to anti-PD-1 alone. Moreover, cells that suppress the immune system from recognizing tumors, such as myeloid-derived suppressor cells (MDSCs), were reduced by more than 40% in the combination with the PS-targeting antibody versus anti-PD-1 alone.

Commenting on data presented at the 2015 ASCO (Free ASCO Whitepaper) meeting, Jeff T. Hutchins, Ph.D., vice president of preclinical research stated, "Measurements of cellular immune activation markers and cytokine profiles in multiple tumor models consistently support the potential of our PS-targeting antibodies to work synergistically with approved and investigational immunotherapies. Our preclinical studies show that combination treatment with an anti-PD-1 antibody yields superior tumor growth inhibition in a larger percentage of subjects while also exhibiting multiple immunostimulatory changes generally associated with anti-tumor immune responses as compared to anti-PD-1 alone. Taken together, these results support the potential of bavituximab to increase the number of subjects whose tumors express increased levels of PD-1 positive T-cells and provide rationale for the clinical evaluation of bavituximab with PD-1 or PD-L1 targeting drugs in lung cancer and other indications."

Avid Bioservices Highlights:
Avid Bioservices reports revenue growth of 20% for FY 2015 with revenues of more than $26 million from contract manufacturing business.

Contract manufacturing committed backlog hits $40 million from existing customers.

Avid makes significant progress toward launching its new state-of-the-art contract manufacturing facility.

"Avid Bioservices had a strong fourth quarter and record fiscal year (FY) generating $9.3 million in contract manufacturing revenue in the fourth quarter of FY 2015 and $26.7 million in contract manufacturing revenue for the full FY 2015," said Paul Lytle, chief financial officer of Peregrine. "We have also continued to see a strong demand for contract manufacturing services that has grown our committed backlog to approximately $40 million. With the new manufacturing facility coming online in the near future, Avid is positioned to meet the growing demand of existing and potential future clients while also preparing for our potential commercial launch of bavituximab."

Corporate – Intellectual Property
The European Patent Office (EPO) granted Patent Number 2,269,656, licensed to Peregrine titled "Selected Antibodies Binding to Aminophospholipids and their Use in Treatment, Such as Cancer." The patent covers bavituximab as a composition of matter and for use in therapy, such as for treating cancer including in combination with radiotherapy or chemotherapy, e.g., with docetaxel. This important patent expands upon the company’s intellectual property portfolio, which now numbers more than 140 worldwide issued patents and pending applications for the bavituximab oncology program.

FINANCIAL RESULTS
Total revenues for the fourth quarter FY 2015 were $9,308,000, compared to $6,474,000 for the same quarter of the prior fiscal year. For FY 2015, total revenues were $26,781,000, compared to $22,401,000 for the prior fiscal year. The fourth quarter FY 2015 and FY 2015 increases were attributed to an increase in contract manufacturing revenue.

Contract manufacturing revenue from Avid’s clinical and commercial biomanufacturing services provided to its third-party clients increased 44% to $9,308,000 for the fourth quarter FY 2015 compared to $6,474,000 for the fourth quarter FY 2015 and increased 20% to $26,744,000 for FY 2015 compared to $22,294,000 for FY 2014. The fourth quarter FY 2015 and FY 2015 increases were primarily attributed to an increase in demand for contract manufacturing services. Current contract manufacturing commitments from Avid’s third-party customers are approximately $40 million, covering services to be provided during FY 2016 and into FY 2017. Based on this current backlog, Peregrine expects contract manufacturing revenue for FY 2016 to be between $30 and $35 million. In addition to providing biomanufacturing services to its third-party customers, Avid will continue to prepare for the potential commercialization of bavituximab.

Total costs and expenses for the fourth quarter FY 2015 were $21,477,000, compared to $17,003,000 for the fourth quarter FY 2014. For FY 2015, total costs and expenses were $77,280,000 compared to $58,107,000 for FY 2014. These increases for both fourth quarter FY 2015 and FY 2015 were primarily attributable to an increase in research and development expenses associated with the Phase III SUNRISE trial. For the fourth quarter FY 2015, research and development expenses were $11,531,000, compared to $8,813,000 for the fourth quarter FY 2014, and for FY 2015 were $42,996,000 compared to $27,723,000 for FY 2014. In addition, cost of contract manufacturing increased 24% to $4,758,000 and 19% to $15,593,000 for the fourth quarter FY 2015 and FY 2015, respectively, primarily due to higher reported revenue compared to the same prior year periods. For the fourth quarter FY 2015, selling, general and administrative expenses were $5,188,000, compared to $4,361,000 for the fourth quarter FY 2014 and for FY 2015 were $18,691,000 compared to $17,274,000 for FY 2014.
