Overview

We are a pioneering clinical-stage immunotherapy company focused on harnessing the power of the innate immune system by using the natural killer cell to treat cancer, infectious diseases and inflammatory diseases. Natural killer, or NK, cells are the body’s first line of defense due to their innate ability to rapidly seek and destroy abnormal cells, such as cancer or virally-infected cells, without prior exposure or activation by other support molecules required to activate adaptive immune cells such as T-cells.

We believe that our proprietary NK cell line, coupled with our planned integrated discovery ecosystem, uniquely positions us to implement precision cancer medicine and potentially change the current paradigm of cancer care by leveraging the advances that have evolved during the past decade and addressing newly discovered challenges of cancer. We believe that many recent advances in cancer treatments have not adequately addressed the heterogeneity of tumor cells, the large mutation load per tumor cell identified by advanced genomics sequencing technologies, and the resistance of the cancer stem cell to chemotherapy. Cancer is only recently understood to be a complex of rare diseases, with hundreds of patient-specific, cancer-promoting mutated proteins, some known and many more unknown. Identifying and targeting these mutated proteins is our strategy to overcome the challenges of cancer in the era of genomics, transcriptomics and immuno-oncology. We believe neoepitopes, which are newly discovered antigens selectively expressed on the cancer cells and not on the essential normal tissue, represent large untapped targeting opportunities for immune effector cells such as our activated NK cells.

Multiple Modes of Tumor Cell Killing. Our immuno-oncology NK platform has multiple modes to potentially induce cell death against the tumor or infected cell by: (1) direct killing by binding to stress ligands expressed by the diseased cell with the release of toxic granules directly into the tumor cell, (2) antibody mediated killing by binding to antibodies administered in combination and enhancing the cancer killing effect of the administered antibody, enabling targeted cell killing through antibody dependent cellular cytotoxicity, or ADCC, and (3) target activated killing by binding to known or newly discovered tumor-specific antigens expressed on the surface of tumor cells and inducing cell death by the release of toxic granules directly into the tumor cell, by the release of cytokines and chemokines which recruit additional innate and adaptive immune responses and by the recruitment of cytotoxic

By implementing an integrated discovery ecosystem and targeting these multiple modes of NK killing of abnormal cells, we believe we are uniquely positioned to potentially address a broad range of known and unknown cancer-promoting mutated proteins and to transform clinical cancer care. Our targeted therapeutic areas include: (1) cancer, focusing on bulky hematological cancers and solid tumors as well as cancer stem cells, (2) infectious diseases, including viral, fungal and bacterial infections, and (3) inflammatory diseases, ranging from rare inherited diseases to more prevalent autoimmune disorders.

Our Integrated Discovery Ecosystem for Precision Medicine. In order to effectively target newly discovered neoepitopes, we plan to integrate the following ecosystem to help drive the development of

genetically modified NK cells anticipated to be directed against these cancer-promoting mutated proteins: (1) a high-speed supercomputing infrastructure to help identify both known antigens on the surface of tumor cells and neoepitopes in clinical patients suffering from cancer, in a timely manner and at large scale; (2) a next-generation genomic and transcriptomic sequencing infrastructure to identify the expression of the neoepitopes on the surface of the tumor cell; (3) a diverse library of human antibodies from which to interrogate and extract an antibody matching the neoepitope; and (4) an NK cell potentially capable of being produced as a scalable, cell-based “off-the-shelf” therapy without the need for patient compatibility matching.

We have assembled a team of proven, experienced and visionary leaders in biotechnology. Our team is led by Patrick Soon-Shiong, M.D., FRCS (C), FACS, our Chairman and Chief Executive Officer. Dr. Soon-Shiong was first introduced to us in 2006 when our technology was at a very early stage of development and, although we did not enter into any investment or employment agreement with him at that time or provide him with any compensation, he provided us with advice and scientific development strategies, including demonstration of activity in the clinical setting following radiation of the cells and demonstration of safety and activity following multiple infusions in patients with both solid and liquid tumors at the end stage of disease. Dr. Soon-Shiong later made an equity investment in our company in December 2014 and joined as our Chief Medical Officer in January 2015 and became our Chairman and Chief Executive Officer in March 2015. Dr. Soon-Shiong, a renowned surgeon and scientist, has pioneered novel therapies for both diabetes and cancer, published over 100 scientific papers in the United States, and issued over 95 patents on groundbreaking advancements spanning myriad fields. He performed the first encapsulated islet stem cell transplant in a diabetic patient in the United States. He invented, developed and launched the first nanoparticle delivery system of human albumin, Abraxane, now approved for metastatic breast, lung and pancreatic cancer and is expected to achieve sales of greater than $1.0 billion in 2015. Dr. Soon-Shiong was founder, Chairman and CEO of American Pharmaceutical Partners (sold to Fresenius SE for $5.7 billion in 2008), Abraxis BioScience (sold to Celgene Corporation for $3.7 billion in 2010) and NantWorks, an ecosystem of companies to create a transformative global health information and next generation pharmaceutical development network. Barry Simon, M.D., our President and Chief Operating Officer, who was our Chief Executive Officer from 2007 until March 2015, brings decades of drug development and executive leadership experience from Hoffmann-La Roche, Connetics Corp. and Immunomedics.

Prior to Dr. Soon-Shiong joining our company at the end of 2014, we focused on developing our aNK cell line, including entering into license agreements with respect to our cell line, conducting pre-clinical studies and clinical trials to evaluate the safety of our aNK cell line as a monotherapy, and filing an IND for our first product candidate. We also genetically modified our aNK cell line to develop our haNK and taNK platforms. The aNK, haNK and taNK platforms are at the center of our business strategy, and Dr. Simon oversaw the development of this technology during his time as our Chief Executive Officer. Subsequent to Dr. Soon-Shiong’s arrival, he has focused on developing our strategic plan, including the development of our planned integrated discovery ecosystem and discovery, research and development of neoepitopes. Additionally, we believe that Dr. Soon-Shiong’s experience and expertise will be valuable to us through all of the phases of commercializing our product candidates.

Our vision is to be the premier immunotherapy company harnessing the power of the innate immune system and the NK cell to pioneer precision medicine in the treatment of cancer, infectious diseases and inflammatory diseases. Our mission is to leverage an integrated and extensive genomics and transcriptomics discovery engine to identify antibodies targeted to newly discovered neoepitopes and to mobilize the human immune system of cancer patients to kill tumor cells and facilitate long-term remission. We expect to regularly add newly discovered neoepitopes from our discovery engine, and we believe the thousands of newly discovered antigens selectively expressed on the cancer cells and not on the essential normal tissue, will provide us with the ability to continue to create new and targeted libraries of antibodies to potentially be delivered as living drugs for metastatic cancer cells and cancer stem cells.

Our Platforms

Direct Killing: aNK Platform. We have developed a unique NK cell which we believe is capable of being produced as a cell-based “off-the-shelf” therapy, with killing potential for cancer and virally-infected cells. Unlike normal NK cells, our NK cells do not express inhibitory receptors, which diseased cells often utilize to turn off the killing function of NK cells. We have developed a unique activated NK, or aNK cell which lacks these inhibitory receptors but retains activation receptors that enable selective targeting and killing of diseased cells. The killing mechanism of our aNK cells is increased compared to normal NK cells by virtue of delivering a larger payload of compounds responsible for the direct killing of diseased cells. We believe our aNK cells can be grown at commercial scale as an on demand, living drug using our proprietary manufacturing and distribution processes.

Safety studies of aNK cells have been conducted in multiple Phase I clinical trials for a variety of bulky hematological cancers and solid tumors enrolling over 40 patients to date, with encouraging evidence of activity and durable remissions. Based on these clinical trials, we plan to develop the therapeutic applications of this aNK platform through molecular engineering of our aNK cells designed to leverage the multiple modes of killing available to aNKs, including antibody-mediated killing, our haNK platform, and antigen targeted killing, our taNK platform, described below.

Antibody-Mediated Killing: haNK Platform. We have genetically modified our aNK cells to incorporate high-affinity CD16 receptors, which bind to antibodies. These high-affinity NK, or haNK, cells are designed to directly bind to externally administered monoclonal antibodies, or mAbs, such as Herceptin, Erbitux and Rituxan and may be able to enhance the cancer killing effect of the externally administered mAbs, enabling targeted cell killing through ADCC. mAbs are prevalently used to treat cancer and generate over $50.0 billion in reported annual sales. We believe, based on currently available information, that only approximately 10% to 20% of the addressable patient population for mAb therapies carry high-affinity CD16 receptors. This implies that our haNK product candidates may have significant market potential as combination therapies to potentially address a large number of patients who have poor responses to mAbs.

Target Activated Killing: taNK Platform. We have genetically modified our aNKs to incorporate chimeric antigen receptors, or CARs, to target specific antigens on the surface of abnormal cells. These target activated Natural Killer, or taNK, cells are designed to directly bind to tumor-specific antigens in multiple bulky hematological cancers and solid tumors and induce cell death by the release of toxic granules directly into the tumor cell, by the release of cytokines and chemokines which recruit additional innate and adaptive immune responses and by the recruitment of cytotoxic T-cells. These tumor-specific antigens can be divided into the following four classes, which can be targeted by our taNK platform: (1) checkpoint inhibitors expressed on the surface of tumor cells such as PDL1; (2) well-established tumor surface antigens such as HER-2, CD33 and ROR1; (3) newly discovered neoepitopes; and (4) novel surface receptors associated with cancer stem cells.

Potential Advantages of Our aNK Platform over T-Cell and Other Immunotherapies

The immune system has two components: innate immune cells, such as NK cells, which are always switched on to attack diseased cells, and adaptive immune cells, such as T-cells, which are mobilized to mount a delayed response. Our proprietary aNK platform is specifically designed to potentially address many of the limitations associated with current adaptive autologous cellular immunotherapies, including the benefits highlighted below. We believe key limitations of adaptive autologous immunotherapy include the need to retrieve non-compromised immune cells from a cancer patient and the requirement for a complex and costly manufacturing process to develop the therapy. As a consequence of this need to harvest active T-cells, current Phase I clinical trials for autologous CAR-T cell therapies in large part enroll patients from highly selected, advanced stage disease in hematological cancers. In contrast, our allogeneic, “off-the-shelf” NK cells do not rely on the patient’s own immune system, which is often compromised, to achieve their therapeutic effect.

Table of Contents

Some of the key potential advantages of our aNK platform are highlighted below.

 

  Innate immune response. aNK cells are always activated and can naturally detect and rapidly destroy a wide variety of diseased cells without prior exposure to pathogens, antigens or activation by stimulatory molecules. In contrast, the adaptive immune system requires co-stimulation for activation, resulting in delayed killing.

 

  Promotion of adaptive immune response. aNK cells stimulate the adaptive component of the immune system by producing chemokines and other molecules that activate and recruit adaptive immune cells, including T-cells, to attack the diseased cells.

 

  Capability of activating both innate and adaptive immune system with a single agent. By combining a PDL1 antibody as a CAR in our NK cells, our PDL1.taNK product candidate, we believe that we have the ability to both activate T-cells and induce direct killing by NK cells simultaneously with the administration of a single therapy.

 

  Wide therapeutic potential across multiple tumor types and even late-stage disease. In preclinical studies and Phase I safety clinical trials to date, aNK cells have demonstrated activity in a spectrum of cancers, including bulky hematological cancers and solid tumors, even in late-stage cancer patients who have failed multiple rounds of chemotherapy, radiation and stem cell transplantation.

 

  Ability to attack cancer stem cells. aNK cells have been shown in preclinical studies to attack cancer stem cells, which are resistant to conventional chemotherapy.

 

  Application in diseases beyond cancer. We believe aNK cells have the potential to treat diseases beyond cancer such as infectious diseases and inflammation because of the inherent ability of NK cells to kill virally infected and abnormal cells. Preclinical studies in Ebola virus demonstrate this capability.

 

  Well tolerated. aNK cells are hypo-immunogenic and have shown no dose limiting toxicities in over 40 patients who have received therapy to date, even when some patients received as many as 18 infusions of aNK cells over six cycles. In contrast, Phase I clinical trials of CAR-T cell therapy report severe adverse toxicities of cytokine release syndrome and neurotoxicity in a number of patients.

 

  Ease of administration. aNK cells may be administrable in outpatient facilities, offering physicians the flexibility to titrate and re-dose therapy based on patient tolerability and need. In contrast, CAR-T cell therapy is a complex and costly procedure, at times requiring hospitalization, pre-conditioning and intensive care unit admission following severe adverse toxicities associated with cytokine release syndrome.

 

  Virtually universal patient compatibility. aNK cells do not require patient-donor matching or a minimum level of patient immuno-competence.

 

  Low-cost, efficient and scalable manufacturing. aNK cells can be cryopreserved, stockpiled and readily accessed on demand from what we believe is the world’s only current good manufacturing practices, or cGMP, compliant NK cell bank, a proprietary asset of our company.

Our Product Candidate Pipeline

We plan to use the data from the Phase I clinical trials of aNK cells conducted to date to serve as the foundation of the development strategy for our three distinct modes of tumor cell killing, each with its own attributes, targeted therapeutic areas and pipeline.

Direct Killing. Our aNK cells have activation receptors that naturally bind to stress-induced proteins. They possess a unique property of resistance to viral counterattack. We are developing our aNK product candidates as monotherapies for the treatment of virally-induced cancers such as polyomavirus induced Merkel cell carcinoma, human Papillomavirus, or HPV, induced cervical cancer and head and neck cancer as well as infectious diseases such as Ebola and other viral, fungal and bacterial infections. We are currently initiating a Phase II clinical trial for our aNK product candidate for Merkel cell carcinoma. Additionally, we intend to pursue combination therapies with low-dose cytotoxic agents and radiation therapy that may augment the ability of our aNK cells to attack cancer cells through these multiple combined points of attack.

Antibody-Mediated Killing. Our haNK cells are genetically engineered to express high-affinity CD16 receptors, designed to enhance the therapeutic efficacy of antibodies through ADCC. We intend to develop our haNK product candidates as combination therapies with widely-used FDA-approved mAbs such as Herceptin, Erbitux and Rituxan. We plan to initiate a Phase I/II clinical trial for our product candidate Herceptin-haNK in 2016. We believe that our haNK product candidates may allow us to potentially address larger markets and earlier lines of treatment. Some biopharmaceutical companies have used our haNK cells as a lot release quality control test for their therapeutic antibodies. If these companies develop and launch these antibodies, we intend to leverage the development performed by these biopharmaceutical companies who have licensed our haNK cells for non-therapeutic use by initiating studies of our haNK product candidates in combination with these antibodies, with the goal of the combination potentially enhancing the activity of these antibodies in patients with low affinity CD16 receptors. We believe this enhanced efficacy provides a rationale for studying haNK cell combinations with these new antibodies, whether during the development phase or after commercial launch by the biopharmaceutical company. We plan to accelerate clinical development of our aNK and haNK product candidates by entering into Phase II and Phase II/III clinical trials with our product candidates in combination with marketed drugs.

Target Activated Killing. Our taNK cells are genetically engineered to directly bind to tumor surface antigens by incorporating CARs to target specific antigens on the surface of abnormal cells. We believe our taNK product candidates may be able to treat patients with bulky hematological cancers and solid tumors, areas in which CAR-T cell therapies have been challenged. We plan to initiate Phase I/II clinical trials for our CD33.taNK product candidate for acute myeloid leukemia, or AML, and our PDL1.taNK product candidate for bulky hematological cancers and solid tumors, in 2016.

We are planning to advance a broad pipeline of aNK, haNK and taNK product candidates with the goal of addressing a wide spectrum of diseases ranging from orphan diseases to more prevalent indications. The following chart highlights some of our near-term opportunities.

Accelerated Clinical Development Plan

We plan to advance our aNK and haNK programs by entering into Phase II and Phase II/III clinical trials with our product candidates in combination with commercially marketed drugs and select product candidates in late-stage development, both mAbs and chemotherapy agents.

mAb combinations. We plan to pursue opportunities for our aNK and haNK programs with pharmaceutical companies for commercially approved mAbs and select late-stage mAbs in development. Over 40 biopharmaceutical companies have licensed our haNK cells for non-therapeutic use in order to select and validate their monoclonal antibodies for development. Certain biopharmaceutical companies have also used our haNK cells as a lot release quality control test for their therapeutic mAbs. Our accelerated strategy is to leverage the development performed by these biopharmaceutical companies by initiating investigator-initiated and company-sponsored Phase II and Phase II/III clinical trials of our haNK product candidates in combination with commercially approved mAbs and select late-stage mAbs in development, with the combination potentially enhancing the activity of these antibodies in patients with low affinity CD16 receptors.

Chemotherapy combinations. A large number of monoclonal antibodies and chemotherapy drugs are being marketed for multiple indications. Published data shows that chemotherapy agents such as 5FU, cyclophosphamide and paclitaxel, when administered in low doses, generally enhance the immune system. We plan to accelerate clinical development of our aNK product candidates by entering into investigator-initiated and company-sponsored Phase II and Phase II/III trials of these product candidates administered in combination with approved chemotherapy agents. The table below describes our accelerated clinical development plan for aNK and haNK product candidates in combination with commercially marketed drugs and select late-stage product candidates in development.

 

Our Strategy

Our goal is to become the leader in the field of immunotherapy by changing the paradigm of care to precision medicine through harnessing the power of the innate immune system, the natural killer cell, to treat cancer, infectious diseases and inflammatory diseases. The key elements of our strategy include:

 

  

Utilize the multiple modes of killing by innate immune therapy. We plan to pursue a comprehensive clinical development plan designed to maximize the commercial potential and clinical knowledge of aNK cells and the role of innate and adaptive immunotherapy as the backbone in the treatment of cancer, as monotherapy and in combination with chemotherapy,

radiation and surgical therapies. We intend to pursue accelerated regulatory approval pathways and attempt to obtain orphan drug status and breakthrough therapy designation, where appropriate, as well as pursue large market opportunities in many solid tumors.

 

  Leverage our integrated discovery engine to discover neoepitopes. Through our strategic collaborations with affiliates of NantWorks and with Sorrento, we plan to identify both known antigens on the surface of tumor cells and neoepitopes in clinical patients, identify the expression of the neoepitopes on the surface of the tumor cell and interrogate a large diverse library of human antibodies and extract an antibody matching the neoepitope. Through this cohesive and expansive discovery engine, we plan to identify antibodies to target newly discovered neoepitopes, thereby driving the development of our product candidate pipeline and establishing just in time precision medicine.

 

  Pursue opportunities with pharmaceutical companies for commercially approved mAbs and select late-stage mAbs in development. Over 40 biopharmaceutical companies have licensed our haNK cells for non-therapeutic use, including as a lot release quality control test for therapeutic antibodies, for them to select and validate their mAbs for development. As a result of these prior non-clinical collaborations for assay testing, we plan to leverage the development performed by these biopharmaceutical companies for therapeutic purposes by initiating studies of our haNK product candidates in combination with these antibodies, with the combination potentially enhancing the activity of these antibodies in patients with low affinity CD16 receptors.

 

  Accelerate clinical development of aNK and haNK by entering into Phase II and Phase II/III clinical trials with our product candidates in combination with marketed drugs and select late-stage product candidates. Published data show that therapeutic mAbs generally have enhanced activity in patients with high-affinity NK cells and that chemotherapy agents such as 5FU, cyclophosphamide and paclitaxel, when administered in low doses, generally enhance the immune system. We plan to accelerate clinical development of our haNK product candidates by entering into investigator-initiated and company-sponsored Phase II and Phase II/III clinical trials of our aNK product candidates administered in combination with commercially approved mAbs and select late-stage mAbs in development or our aNKs in combination with approved chemotherapy agents.

 

  Establish low-cost, scalable manufacturing capabilities to support late-stage clinical trials and global commercialization. We believe our aNK cells offer a unique advantage of a simplified, on-demand manufacturing process that is relatively easy to scale. We are building a state-of-the-art, cell-based manufacturing facility with the capacity to support large-scale clinical trials and commercialization. We are developing novel manufacturing methods, both in equipment utilizing state-of-the-art optics and proprietary media designed to maximize the attributes of our NK platform.

 

  Extend our NK platform to address diseases beyond cancer. We believe our aNK cells have the potential to treat diseases beyond cancer such as infectious and inflammatory diseases because of the inherent role of NK cells to kill virally infected and abnormal cells. Preclinical studies in Ebola virus demonstrate this capability. In addition to Ebola, we plan to investigate and develop our aNK cells for the treatment of HIV, tuberculosis and influenza, among others.

Risks Associated with Our Business

Our business is subject to numerous risks, as more fully described in the section entitled “Risk Factors” immediately following this prospectus summary. You should read these risks before you invest in our common stock. We may be unable, for many reasons, including those that are beyond our control, to implement our business strategy. In particular, risks associated with our business include:

 

  We are a clinical-stage biopharmaceutical company with a limited operating history and have incurred significant losses since our inception, and we anticipate that we will continue to incur losses for the foreseeable future;

 

  The foundation of our business is based upon the success of our aNK cells as a technology platform. Our aNK platform and other product candidate families, including genetically modified taNK and haNK product candidates, will require significant additional clinical testing before we can potentially seek regulatory approval and launch commercial sales;

 

  Utilizing aNK cells represents a novel approach to immunotherapy, including cancer treatment, and we must overcome significant challenges in order to successfully develop, commercialize and manufacture our aNK and other product candidates;

 

  Even if we successfully develop and commercialize our aNK product candidate for Merkel cell carcinoma, we may not be successful in developing and commercializing our other product candidates and our commercial opportunities may be limited;

 

  We may not be able to file investigational new drug applications, or INDs, to commence additional clinical trials on the timelines we expect, and even if we are able to, the FDA may not permit us to proceed in a timely manner, or at all;

 

  We face significant competition in the biopharmaceutical industry, and many of our competitors have substantially greater experience and resources than we have;

 

  Our business plan involves the creation of a complex integrated ecosystem capable of addressing a wide range of indications. As a result, our future success depends on our ability to prioritize among many different opportunities;

 

  Our planned ecosystem is to be comprised of multiple novel technologies that have never been tested in combination with our product candidates, and we do not know whether our attempts to use them in combination will be effective;

 

  Clinical drug development involves a lengthy and expensive process with an uncertain outcome, results of earlier studies and clinical trials may not be predictive of future clinical trial results, we may not be able to rely on the aNK Phase I clinical trial data for our other product candidates, and our clinical trials may fail to adequately demonstrate substantial evidence of safety and efficacy of our product candidates;

 

  We do not have any therapeutic products that are approved for commercial sale. Our ability to generate revenue from product sales and become profitable depends significantly on our success in a number of factors;

 

  We will need to obtain substantial additional financing to complete the development and any commercialization of our product candidates;

You guys know we’ve never stopped anyone from using ad-blockers, therefore it doesn’t make any income to our site running cost. also we are not using any premium file hosting website, all our contents (like cracks, keys, software) are hosted in free websites like zippyshare, upload.ee, etc… thus our incomes are very low. currently we are using adf.ly and bc.vc for maintaining our cost, but now our ad revenue has declined to less than 20 USD a month.So, we request everyone to contribute fast if possible to do so.

  3. Patches/keygens are not a virus or Trojan. Patches/keygen made by by-passing the original registration of software, so anti-virus may detect it as Trojan or virus.
  4. Therefore, use patches or keygens posted on our website without any worries. All our contents are trustable as they all come from trustable sources.
