NantKwest to Present Updated Preclinical Data at the 60th Annual Meeting of the American Society of Hematology
NantKwest Inc. (Nasdaq:NK), a pioneering, next generation, clinical-stage immunotherapy company focused on harnessing the unique power of our immune system using natural killer (NK) cells to treat cancer, infectious diseases and inflammatory diseases, today announced an abstract/poster presentations will be given at the upcoming 60th Annual Meeting of the American Society of Hematology (ASH) in San Diego, CA, which runs from December 1-4, 2018.
Presentation Title: Providing a Homing Receptor for CAR Engineered NK Cells - Improving Cellular Immunotherapy for B-Cell Lymphoma
Presenter: Nathan Thomas Schomer, Laurent Boissel, Karen Jiang, Hans Klingemann, John Lee, and Patrick Soon-Shiong, NantKwest, Inc., Culver City, CA
Date: Monday, December 3, 2018, 6:00-8:00pm
Location: San Diego Convention Center, Hall GH
NantKwest’s proprietary natural killer (NK) therapy is based on an activated natural killer cell platform (aNK) derived from a novel cell line with potent cytotoxicity. With over 400 doses safely administered to over 80 patients across multiple Phase I/II clinical trials, NantKwest’s off-the-shelf therapies have demonstrated encouraging clinical responses across a broad range of cancer cell types.
The company’s haNK® cells, currently in multiple human clinical trials, have been engineered to carry a high-affinity version of the CD16/FcγRIII receptor that binds to the Fc portion of a monoclonal antibody to enhance the cancer cell killing effect when used in combination with haNK cell therapy.
As part of our next-generation NK cell therapy program, we further enhanced the potential targeting and homing efficiency of haNK cell therapy by incorporating both a CD19-targeting CAR, together with the chemokine-homing receptor, C-C Chemokine Receptor Type 7 (CCR7), which targets both Chemokine (C-C motif) ligand CCL19 (CCL19) and Chemokine (C-C motif) ligand 21 (CCL21), key signaling molecules expressed in lymph nodes to guide homing to these tissues. This tri-targeting NK cell therapy is designed to maximize NK cell activity by increasing NK cell migration to tumor sites and enhance cancer cell killing activity through both CD19-targeted, CAR-mediated killing, together with antibody mediated killing when combined with monoclonal clonal antibodies such as Rituximab.
Dr. Patrick Soon-Shiong, Chairman and CEO of NantKwest commented, “We look forward to reporting preclinical data on this novel tri-specific, off-the-shelf, homing CD19.t-haNK cell therapy. By engineering a novel chemokine-based CAR, into our off-the-shelf NK cell platform, we show that we can increase NK cell migration to target cancer cells and this enhanced homing can potentially maximize NK cell-driven immunogenic cell death. Representing what we believe will be an attractive treatment option, we are now focused on transitioning this next-generation NK cell therapy program to human clinical trials as rapidly as possible.”
About NantKwest Inc.
NantKwest is an innovative 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.
NantKwest is uniquely positioned to implement precision cancer medicine, with the potential to change the current paradigm of cancer care. Natural Killer cells are ancient cells in the human body designed to recognize and detect cells under stress or infected. The NantKwest “off-the-shelf” activated Natural Killer (NK) platform has the capacity to destroy cancer and virally infected cells from the body. The safety of our NK cells as well as their activity against a broad range of cancers have been tested in multiple phase 1 clinical trials in the United States, Canada and Europe. In addition to our NK cells capability to be administered in the outpatient setting as an “off-the-shelf” living drug, serves as a universal cell-based therapy without need for individualized patient matching. Moreover, our NK cell based platform has been bioengineered to incorporate chimeric antigen receptors (CARs) and antibody receptors to further optimize targeting and potency in the therapeutic disease.
