Phase I: Vaccine Therapy in Treating Patients With Previously Treated Stage II-III HER2-Positive Breast Cancer
The purpose of this study is to look at the safety and immune response to a vaccine used in patients previously treated for HER2 (human epidermal growth factor receptor 2) positive breast cancer.
Data published at ASCO 2015. 20 out of 21 clinical trial subjects proved the drug to be safe, easily tolerated, and, remarkably, 100% had a successful immune response.
Phase I: Vaccine Therapy and Cyclophosphamide in Treating Patients With Stage II-III Breast or Stage II-IV Ovarian, Primary Peritoneal, or Fallopian Tube Cancer
This phase I clinical trial studies the side effects of vaccine therapy and cyclophosphamide in treating patients with stage II-III breast cancer or stage II-IV ovarian, primary peritoneal or fallopian tube cancer. Vaccines made from peptides may help the body build an effective immune response to kill tumor cells. Drugs used in chemotherapy, such as cyclophosphamide, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving vaccine therapy and cyclophosphamide may kill more tumor cells.
Phase II: TPIV200/huFR-1 (A Multi-Epitope Anti-Folate Receptor Vaccine) Plus Anti-PD-L1 MEDI4736 (Durvalumab) in Patients With Platinum Resistant Ovarian Cancer
This is a Phase 2 clinical trial, which tests two investigational drugs: TPIV200/huFR-1 (also called TPIV200), which is a vaccine consisting of proteins from the folate receptor alpha mixed with GM-CSF, and durvalumab (MEDI4736) , which is an antibody drug that help un-block parts of the immune system. The aim of this study is to find out whether these drugs, when given together are safe, and whether they are effective in treating cancer.
Phase II: Folate Receptor Alpha Peptide Vaccine With GM-CSF in Patients With Triple Negative Breast Cancer
This Phase II trial evaluates the safety and immunogenicity of two doses of the Folate Receptor Alpha (FRα) peptide vaccine mixed with GM-CSF as a vaccine adjuvant, with or without a immune priming with cyclophosphamide, as a consolidation therapy after neoadjuvant or adjuvant treatment of patients with Stage IIb-III triple negative breast cancer (TNBC).

Innovative Immunotherapies in Oncology and Infectious Diseases
TapImmune Inc. ("TapImmune" "TPIV") is a biotechnology company specializing in the development of innovative therapeutics and vaccines in the areas of oncology and infectious disease. TPIV technologies are based on an understanding of the function of a protein known as TAP. Transporters Associated with Antigen Processing (TAP) are proteins responsible for supplying tumor-associated antigens (markers) and viral antigens to the surface of infected cells.
These markers are required for the effective recognition and destruction of cancer cells and virus infected cells by the immune system. A wide variety of metastatic cancers evade destruction by the immune system due to absent or insufficient amounts of TAP, making the tumors unrecognizable.
TPIV's lead product, the TAP vaccine performs a key step in moving characteristic markers called antigens to the surfaces of cells allowing the recognition and killing of cancer cells by the immune system. Without TAP, there are no cancer markers, so the immune system fails to spot the rogue cells and the cancerous cells can grow undetected.
Clinical studies to date have identified a large number of cancers deficient in TAP including but not limited to HPV related cancers such as melanoma, lung, prostate, breast and ovarian cancer. TapImmune believes these tumors would be responsive to the TAP therapeutic vaccine. In preclinical trials for melanoma and lung carcinoma, animal survival rates of 70% were achieved using TAP vaccine therapy and 100% survival when TAP was administered ex-vivo.
TPIV's vaccine has shown effective restoration of TAP and the TAP molecule also works as an adjuvant or to enhance targeted vaccines against infectious diseases. Including TAP in the much studied Smallpox Vaccine, its potency was increased by 100-1000 times. TPIV is currently developing models for the application of this technology for some of the most important societal pathogens.
This is a new paradigm in the treatment of infectious disease and could significantly advance the development of new vaccines as well as improve those that already exist.
Seattle-based biotechnology innovator TapImmune Inc. is on to something big, very big. The company has engineered a remarkable, yet elegantly simple, way for the body to recognize tumour and infectious disease cells and provoke an aggressive immune response whereby the body's own killer T-Cells attack and eradicate harmful foreign bodies. This with respect to any form of cancer or disease via a technology that's entirely non-discriminate in helping the body eradicate dangerous cells of many kinds.
Underscoring the vast potential of TapImmune's approach is its exclusive licensing option agreement with the Mayo Clinic for a breast cancer antigen technology complementary to the company's TAP (AdhTAP) protocol. In a novel approach, TapImmune and the Mayo Clinic will co-develop a specialized vaccine for patients with very aggressive HER2/neu breast cancer. What's unique is that TapImmune's technology actually re-activates the body's own immune system, triggering mission-critical self-curative mechanisms that would otherwise not function properly.
"We chose to work with the Mayo Clinic because they have great clinical expertise in breast cancer, and we're focusing specifically on HER2/neu breast cancer because we found complementary technology with Mayo that will work with TAP and address the problems found with earlier approaches," explains Dr. Glynn Wilson, chairman and CEO of TapImmune. "Importantly, we're able to work with a leading expert on breast cancer vaccines, Dr Keith Knutson of the Mayo Clinic, who will conduct the trials. Through these trials, we'll also address a huge clinical need for patients who express low to moderate levels of HER2/neu and are not candidates for treatment with Herceptin(R) (trastuzumab), an intravenously delivered monoclonal antibody."
How it Works
Simply put, TAP (transporters associated with antigen processing) plays a major role in the complex human immune system. When foreign bodies (viruses and disease) attack cells in the body, the normal response is for killer T-cells to find those invaders and destroy them. TAP is a transporter that helps trigger an immune response by providing a pathway for tumour antigens to be expressed on the surface of the cell. In most solid cancers TAP levels are greatly reduced, which prevents the antigen presentation required to stimulate T-cells into action.
In the treatment of cancer, TAP is analogous to turning on the light bulb on the surface of tumour cells, allowing immune cells to "see" them and inspire action accordingly. For infectious disease treatment, TAP turns the light bulb to a higher intensity to prompt more immune cells to act.
TAP potentially allows the immune system to see everything that's foreign on the surface, in contrast to other approaches that simply focus on a single tumour antigen to try and raise an immune response. Indeed, TapImmune's technology is entirely unique in that it isn't dependent on genetics such as other immunotherapies and doesn't directly target the tumour cells, but instead assists the body's own immune system to do what it was designed to do by turning the TAP back on and activating destroyer T-Cells into "kill" mode.
TAP and Breast Cancer
Wilson says with any vaccine, there are two requirements needed to create a good immune response: 1) stimulate the cytotoxic lymphocyte (Class 1 pathway) and 2) stimulate the pathway that stimulates the T helper cells (Class 2 pathway), which gives a long-lasting immune response. The failure to satisfy both of these requirements is one of the reasons other breast cancer vaccines haven't progressed.
For breast cancer, we are developing a unique multicomponent vaccine that stimulates the Class 2 pathway (CD4 - helper cells) for a prolonged immune response and the Class 1 pathway (CD8 - cytotoxic T cells) to activate killer T-cells that will infiltrate and destroy tumour cells. The HER2/neu vaccines that had been tested in the past either do not stimulate sufficient cytotoxic T-cell response on the Class 1 pathway or they do not give a long-lasting effect. I realized that we have the capability here with the Mayo technology plus TAP of creating good responses on both sides of the immune system required for a good vaccine. It is a very innovative, creative and exciting approach."
In the overall vision of the use of cancer vaccines, the ultimate goal is to have vaccines that can be used prophylactically at the earliest detection of pre-cancerous conditions such as DCIS, Corin continues. It is thought that the more advanced the cancer, the lower the TAP levels will be. TAP may be applicable to all stages of cancer if we consider experiments that treated smallpox, augmenting the normal levels of TAP and making a smallpox vaccine fully 100 to 1000-fold more potent.
The immune system distinguishes normal and cancerous (or virus-infected) cells by monitoring major histocompatibility complex (MHC) Class 1, a molecule on the cell's surface. Nearly all cell types display MHC Class 1 antigen on their surface, continually providing information to the immune system. The MHC molecule, which contains small protein fragments (peptides), cycles to the surface of the cell to present foreign antigens to the cellular immune system, thereby activating the cytotoxic T-cells to kill virus-infected or cancerous cells.
In many cancers, there is a disruption in the process and the MHC on the cell surface is missing the tumour antigen peptides that identify the cell as being cancerous. They are basically hidden from the immune system and grow into tumours that eventually kill the person. Because TAP is affected negatively in the disease process, TapImmune's vaccine technology turns TAP back on, supplying peptides to the MHC Class 1 molecule. TAP facilitates the binding of foreign peptides to the MHC Class 1 molecule. TAP facilitates the binding of foreign peptides to the MHC Class 1 complex, displaying them on the cell's surface. Cytotoxic T-cells recognize them as foreign and ultimately neutralize and destroy abnormal cells.
Clinical studies on melanoma when examining primary and metastatic (spreading) tumours show a clear and significant correlation between TAP expression and survival.
The History and Future of TAP Technology
TapImmune was formed in Vancouver, British Columbia, in the laboratories of immunologist Wilfred Jeffries, who with his colleagues produced exciting data showing that administration of TAP to replace deficient levels in tumours or augment natural levels in viral disease had significant therapeutic effects in animal models.
TapImmune principals acquired the technology and intellectual property outright from the university and set out to put together a board of directors and advisory board that understands the technology and its potential and to partner with credible collaborators like the Mayo Clinic and Aeras Global TB Vaccine Foundation, an organization largely funded by the Gates Foundation.
In discussions with Aeras Global TB Vaccine Foundation, we identified the potential of TAP for use in the joint development of their next-generation TB vaccine, said Denis Corin, TapImmune's president and CFO. But you could also look at influenza, SARS, HIV, H1N1 and many other societal pathogens. We're also working with Dr Poland and the Mayo Clinic on a new small pox vaccine. But, small pox is the tip of the iceberg. There are a number of nasty viruses that are potential bioterrorism threats and governments around the world could stockpile our TAP vaccine and call on it in the event of a bioterrorist threat.
