Dr. Miller will be presenting to leaders in the field of cell therapies at the conference on Feb. 14th from 5:00 -7:00 pm MT. He will be discussing GT Biopharma’s unique single-chain, tri-specific NK cell engager (TriKE) and tetra-specific NK cell engager (TetraKE) platforms targeting hematologic malignancies, sarcomas and carcinomas (solid tumors). The presentation will address both the TriKE and TetraKE constructs, as well as our second-generation anti-CD16-IL-15-anti-CD33 TriKE (OXS-C3550); another first-of-its-kind, single-chain, tri-specific NK cell engager (TriKE).

NK cell cancer-killing activity is expected to be increased by bringing the NK cells in close proximity to the cancer cells. This may be achieved by ‘engagers’ that bind to CD16 on the surface of NK cells and bind specific proteins (such as CD33) on the surface of cancer cells, thus forming an immune synapse between the NK cell and the cancer cell. Our lead TriKE, anti-CD16-IL-15-anti-CD33 (OXS-3550) is expected to be in the clinic in the second half of 2018. The TriKE constructs utilize the inclusion of interleukin-15 (IL-15), a peptide that leads to proliferation and activation of the NK cells. This further increases NK cancer-cell killing capabilities and improves their function in the tumor microenvironment (Vallera et al,2016).

Unlike traditional CAR-T platforms, TriKEs are potentially a cost effective cell therapy and not relegated to treating liquid tumors only. GT Biopharma believes that TriKEs are an antibody platform that can be tailored to treat any form of cancer, liquid or solid tumors.

Dr. Jeffrey Miller said, "I am pleased to present additional information regarding these immune-oncology platforms. As a researcher, I continue to believe that both have the potential to generate candidates with the ability to have a significant impact on the treatment of cancer and other diseases."

GT Biopharma Chief Medical officer (CMO) Dr. Raymond Urbanski said, "The TriKE and TetraKE concepts and constructs potentially have significant advantages over current and other development-stage therapies. Dr. Miller is a luminary in NK cell biology and its applications, and we continue to be excited by the potential opportunity related to this technology."

Glioblastoma multiforme is the most common and deadliest of the glial tumors because it is hard to cure with a very high possibility of recurring. Diffuse intrinsic pontine glioma (DIPG) is a sub-kind of glioblastoma that mainly affects children. It has a 5-year survival rate less than 1%.

The presentation entitled "TRAP CAR-T and Related Cell Therapies: Can Local Delivery Solve Efficacy and Toxicity Challenges in Solid Tumor Immuno-Oncology?" will discuss Atossa’s proprietary intraductal microcatheter technology and its potential to deliver T-Cell and other immunotherapies directly to breast cancer tumors.

Janet Rea, MSPH, RAC, Senior Vice President of Regulatory, Quality and Clinical Affairs for Atossa will present. Ms. Rea joined Atossa in 2015 and has over 35 years of industry leadership experience. A Washington native, she obtained her B.S. degree in Microbiology from the University of Washington and was conferred a Master’s of Science of Public Health from the same institution.

About The Molecular Medicine Tri-Conference

The annual Molecular Medicine Tri-Conference has become one of the world’s leading international events in the field of drug discovery, development and diagnostics. The Tri-Conference unites an ecosystem of 3,700 innovative thinkers and thought leaders throughout biotech, pharma and academia from around the world. Spanning five days (February 11 – 16) the 2018 meeting includes 16 parallel conference tracks, 7 Symposia, and 25 in-depth short courses.

About Atossa’s CAR-T Technology

Much of the recent success in the field of chimeric antigen receptor therapy, or CAR-T, has relied on the systemic delivery (for example a needle injection into the blood stream) of the CAR-T which is intended to treat various non-solid tumor cancers, such as blood cancers. One concern with this systemic approach is that it does not target the location of the cancer and it can have adverse affects, including deadly "cytokine storms." Moreover, CAR-T treatments delivered systemically can be very expensive – as high as $500,000 per patient.

We are developing a novel method to deliver CAR-T cells into the ducts of the breast for the potential targeted treatment of breast cancer. This approach uses our proprietary intraductal microcatheter technology for the potential transpapillary, or "TRAP," delivery of either T-cells that have been genetically modified to attack breast cancer cells or various immune-therapies. We believe this method has several potential advantages including the reduction of toxicity by limiting systemic exposure of the T-cells or immunotherapy; improved efficacy by placing the T-cells or immunotherapy in direct contact with the target ductal epithelial cells that are undergoing malignant transformation; and, lymphatic migration of the CAR-T cells or immunotherapy potentially extending their cytotoxic actions into the regional lymph system, which could limit tumor cell dissemination. Moreover, our proprietary approach may be more cost effective if lower doses of therapy can be delivered compared to systemic CAR-T. Our approach is in the R&D stage and is currently not FDA approved. In 2018 we intend to commence studies that will help demonstrate safety and efficacy of this novel approach.

On February 13, 2018 MEI Pharma, Inc. (NASDAQ: MEIP), an oncology company focused on the clinical development of novel therapies for cancer, reported that a planned interim review of data supports continuation of its multicenter, investigator sponsored, study evaluating ME-344, a novel mitochondrial inhibitor, in patients with HER2-negative breast cancer (Press release, MEI Pharma, FEB 13, 2018, View Source [SID1234523949]). The interim study data show that ME-344 was generally well-tolerated and, consistent with previous preclinical data, demonstrate the potential to reverse resistance to antiangiogenic therapy. Based on the interim results, it was determined that completion of enrollment of the clinical study of ME-344 in combination with bevacizumab (marketed as Avastin) is warranted.

"The interim data are very encouraging and I look forward to an opportunity to present the results at a medical meeting later this year," stated the study principal investigator, Miguel Quintela-Fandino, M.D., Ph.D., Director of the Clinical Research Program, Centro Nacional De Investigaciones Oncologicas, Madrid, Spain.

Dr. Quintela-Fandino continued: "These preliminary data are consistent with our previously published preclinical studies and it is our hope that the data from the current clinical study will help advance our understanding of the escape pathways utilized by tumors against antiangiogenic agents. The therapeutic opportunity that is available to exploit the adaptive mechanisms of tumors via mitochondrial inhibition is quite novel and I am very excited to continue the trial and further explore the promising utility of ME-344 in combination with antiangiogenic therapeutics."

Inhibition of mitochondrial adenosine triphosphate (ATP) with drug candidates such as ME-344 may have significant potential in combination with antiangiogenic agents. Antiangiogenics are widely used biologic agents in oncology, but acquired resistance to antiangiogenics is a major problem in cancer therapeutics. Antiangiogenics reduce the rate of glycolysis as a mechanism to block tumor growth, however sustained tumor growth may be achieved via a shift to an alternative metabolic energy source such as mitochondrial ATP*. In such cases of tumor plasticity in the presence of treatment with antiangiogenics, targeting the alternative metabolic source would open an important therapeutic opportunity.

About the Study
The study is a multicenter, investigator sponsored, randomized, open label, clinical trial evaluating ME-344 in a total of 40 patients with HER2-negative breast cancer in combination with the VEGF inhibitor bevacizumab (marketed as Avastin). Patients are randomized one-to-one to either ME-344 plus Avastin or saline plus Avastin. The primary efficacy endpoint is inhibition of cell proliferation as measured by Ki-67 reductions. The interim data review was predefined to take place after 20 patients were randomized.

About ME-344
ME-344 is a novel, tumor selective, isoflavone-derived mitochondrial inhibitor drug candidate. It directly targets the OXPHOS complex 1**, a pathway involved in the production of adenosine triphosphate, or ATP, in the mitochondria. Treatment of tumor cells with ME-344 results in a rapid loss of ATP and cancer cell death. ME-344 has demonstrated evidence of single agent activity against refractory solid tumors in a Phase 1 study.
