Tumor Microenvironment and NK Cell Therapy

9:30 am Distinguishing Undifferentiated Tumors from Differentiated Tumors

  • Anahid Jewett Professor & Director of Tumor Immunology Laboratory, UCLA School of Dentistry and Medicine

Synopsis

  • NK cells are the effectors of selection and differentiation of Cancer Stem Cells/ undifferentiated tumors in pancreatic, melanoma, glioblastoma, lung, breast and oral tumors
  • We have identified and characterized combination of surface receptor markers which distinguish stem-like/undifferentiated tumors from differentiated tumors and have used to identify the degree and effectiveness of patient NK cells in differentiation of tumors
  • Membrane bound and secreted forms of IFN-g and TNF-a from NK cells are key cytokines in limiting tumor growth through differentiation of the tumors
  • NK inactivation occurs at the pre-neoplastic stage of tumorigenesis and becomes more severe at the neoplastic stage due to both the genetic and environmental factors
  • Factors contributing to the dysfunctional state of cancer patients’ NK cells are lack of expansion of NK cells, severe decrease in NK cell cytotoxicity, decreased secretion of IFN-g by the NK cell and lack of ability of secreted IFN-g to differentiate tumors

10:00 am NK Cells and the Solid Tumor Microenvironment: Lessons Learned and Translational Potential

  • Robin Parihar Assistant Professor of Pediatric Hematology- Oncology , Baylor College of Medicine

Synopsis

  • Understand the role of the tumor immune microenvironment in patients receiving adoptive cellular therapy

10:40 am
Morning Refreshments & Networking

11:00 am Harnessing NK Cells to Improve T-Cell Targeted Immunotherapies for Solid Tumor and Hematologic Malignancies

  • Amir Horowitz Assistant Professor of Oncological Sciences, Ichan School of Medicine

Synopsis

  • Exploring the under-appreciated layer of complexity around HLA-E-mediated inhibition and regulation of NK cell functions in the tumor microenvironment
  • Examining the effects of HLA-E expression and presence or absence of KIR ligands on tumor cells on prognosis and survival of cancer patients across numerous settings of hematologic and solid tumor mali gnancies
  • Tumor response to immune checkpoint blockade therapies

11:30 am GAIA-102 as the NK Cell-Based ‘Upward Compatible’ Modality Over CAR-T Cell Therapy

Synopsis

  • GAIA-102 is a novel immature phenotype of NK cells with massive killing activity
    for various types of malignancies
  • GAIA-102 eliminates spheroid-forming tumors that are highly resistant to CAR-T cells
  • Gene expression pattern of GAIA-102 is very close to those of CAR-T cells rather
    than of NK cells
  • GAIA-102 is a promising candidate for adoptive immunotherapy for solid tumors
    as an ‘upward compatible’ modality over CAR-T cell therapy

12:00 pm Panel Discussion: Identifying Strategies to Improve Efficacy in Solid Tumor Trials

  • Amir Horowitz Assistant Professor of Oncological Sciences, Ichan School of Medicine
  • Anahid Jewett Professor & Director of Tumor Immunology Laboratory, UCLA School of Dentistry and Medicine
  • Mark Lowdell CSO, ImmuneBio Inc

Synopsis

  • Strategies to allow NK cells to cross barriers into solid tumors and overcome strong immunosuppressive environments
  • Do immune-regulatory cells impact NK and T cells in the same way?
  • Discuss the potential of downregulating TGF-beta to allow for greater NK activity

1:00 pm
Lunch & Networking

Clinical Trial Case Studies

Synopsis

Hear updates on the most advanced clinical programs to discover how the application of NK cell therapies are being successfully utilized in the clinic.

2:00 pm Pre-Emptive Donor-Derived Natural Killer Infusion for Patients with High-Risk Multiple Myeloma, Lymphoma, or CLL

  • Noah Merin Assistant Professor, Cedars-Sinai Medical Center

Synopsis

  • Attempting to add-back mature donor NK and NK/T cells after PTCy to hasten NK immune recovery
  • Outlining the two separate pheresis sessions donors undergo
  • Methods to evaluate abundance of NK receptor ligands, NK phenotype, KIR expression and inhibitory/activating receptors

Addressing NK Cell Expansion

2:30 pm NK Cell Stimulation Using Membrane Bound IL-21

Synopsis

  • Addressing the needed for an effective and robust methodology for efficient production of large doses of NK cells with high anti-tumor potency
  • NK cell stimulation for production of high dosages and repeat dosages of highly potent NK cells.
  • Advancing clinical development of NK cell therapeutics for treatment of AML in the near future

3:00 pm Addressing Contact-Dependent Factors that Promote NK Cell Development

  • Emily Mace Assistant Professor of Pediatrics, Columbia University

Synopsis

  • Human natural killer (NK) cell development is a poorly understood process, particularly the nature of cell-cell contacts that shape NK cell functional maturation
  • Understanding the contact-dependent factors that promote NK cell development will better inform the design of rational NK cell-based immunotherapy
  • Here I will describe recent findings that have advanced our understanding of the generation of NK cell heterogeneity and functional phenotypes using novel in vitro and ex vivo systems

3:30 pm
Afternoon Refreshments

4:00 pm Antibody-Cell Conjugation to NK Cells Without Genetic Engineering

  • Sonny Hsiao CEO, President and Co-Founder, Acepodia Inc.

Synopsis

  • Novel technology ACC (Antibody-Cell Conjugation) to chemically conjugate antibodies to NK cells without genetic engineering
  • Signaling pathways activated by novel ACC-NK

4:30 pm Discussing the Impact of Different Factors on Successful NK Cell Cryopreservation

  • Dean Lee Professor of Pediatrics, Nationwide Children's Hospital

Synopsis

  • NK cells are difficult to cryopreserve, with poor recovery of viability and function under
    conditions that work well for other lymphocytes (e.g., CAR-T cells), which has limited their
    potential in adoptive immunotherapy
  • We will discuss the impact on successful NK cell cryopreservation of IL-21 signaling,
    cryopreservation media, freezing programs, and cell density
  • Data on biomarkers of successful cryopreservation and clinical data that demonstrate
    survival and functionality of cryopreserved NK cells
