14:05 A New Era in Cancer Therapeutics: Biologic Problems and Engineering Solutions

Chen_DanielDaniel Chen, MD, PhD, Chief Medical Officer, IGM Biosciences

The opportunity for therapeutics that turn on or off a singular target has largely been explored. However, advancements in our understanding of cancer, immune biology, and protein/cellular engineering approaches begin to define what seemed like science fiction only a few years ago. The objectives and challenges for next-generation therapy and spatial temporal coordination of modulating different biologies and cell types within emerging cancer immunotherapy will be explored.

14:35 Novel Antibody Engineering to Improve Therapeutic Index of Antibody Targeting Solid Tumors

Tatsumi_KanakoKanako Tatsumi, PhD, Researcher, Discovery Biologics, Chugai Pharmaceutical Co. Ltd.

One of the remaining issues of antibody therapeutics is on-target off-tumor toxicity induced by binding to target antigens expressed in normal tissues. To overcome this issue, we have established a novel antibody engineering technology to enable antibody to bind the antigen selectively at tumor site, but not at normal tissues.

15:05 Alternative Strategies to Control Light Chain Diversity in Transgenic Chickens

Bill Harriman, Vice President, Antibody Discovery Services, Ligand

OmniChicken® V gene diversity in B cells can be controlled through rational design of synthetic pseudogenes inserted into the Ig loci. One design, for the purpose of conventional HxL antibodies, results in extensive diversity focused in CDR regions, and the other design, for the purpose of common light chain antibody development, results in minimal diversity across the entire V region.

16:00 Avidity-Based Binding to HER2 Results in Selective Killing of HER2 Over-Expressing Cells by Anti-HER2/CD3

Junttila_TeemuTeemu Junttila, PhD, Senior Scientist, Translational Oncology, Genentech, Inc.

A primary barrier to the success of T cell-recruiting bispecific antibodies in the treatment of solid tumors is the lack of tumor-specific targets, resulting in on-target off-tumor adverse effects from T cell autoreactivity to target-expressing organs. To overcome this, we developed an anti-HER2/CD3 T cell-dependent bispecific (TDB) antibody that selectively targets HER2-overexpressing tumor cells with high potency, while sparing cells that express low amounts of HER2 found in normal human tissues. Selectivity is based on the avidity of two low-affinity anti-HER2 Fab arms to high target density on HER2-overexpressing cells. The increased selectivity to HER2-overexpressing cells is expected to mitigate the risk of adverse effects and increase the therapeutic index.

16:30 Tumor-Targeted 4-1BB Co-Stimulation to Boost T Cell Activity for Cancer Immunotherapy

Klein_ChristianChristian Klein, PhD, Head of Oncology Programs & Department Head of Cancer Immunotherapy Discovery, Roche Innovation Center Zurich, Roche Pharmaceutical Research and Early Development (pRED)

Endogenous costimulatory molecules on T cells, such as 4-1BB (CD137), can be leveraged for cancer immunotherapy. To overcome issues of first generation 4-1BB agonistic antibodies, we engineered proteins simultaneously targeting 4-1BB and a tumor-stroma or tumor antigen (TA): FAP-4-1BBL (RG7826) and CD19-4-1BBL. In the presence of a T cell receptor (TCR) signal (endogenous or provided by a T cell bispecific antibody), they provide potent T cell costimulation strictly dependent on tumor target-mediated hyper-clustering without systemic activation by FcgR-binding.

08:30 Chairperson’s Remarks

Daniel Chen, MD, PhD, Chief Medical Officer, IGM Biosciences

08:35 Agonist and Bispecific IgM: Nature’s Approach to Highly Avid, Multivalent Antibodies

Keyt_BruceBruce Keyt, PhD, CSO, IGM Biosciences

Death receptor 5 (DR5) is widely expressed on tumor cells and directly induces apoptosis. Agonistic IgG anti-DR5 has preclinical efficacy, but not clinical efficacy. Multivalent IgM anti-DR5 induces receptor clustering and rapid tumor cell apoptosis. In vitro, anti-DR5 IgM was 1,000-fold more potent compared to anti-DR5 IgG. In vivo, anti-DR5 IgM eradicated colorectal tumors and extended survival with leukemic models. We are developing IgM anti-DR5 for treatment of solid and hematologic tumors.

09:05 Insights into the Mechanism of Action of ImmTAC® Molecules in Melanoma Patients

Lepore_MarcoMarco Lepore, PhD, Group Leader, Immunocore LLC

Immune mobilising monoclonal TCRs Against Cancer (ImmTAC) molecules are soluble bispecific T cell engagers which use high affinity TCRs fused to an anti-CD3 scFv to redirect polyclonal T cells toward tumor cells. ImmTAC molecules target tumour antigen-derived peptides naturally presented by HLA molecules on the surface of cancer cells and induce multiple cytolytic and pro-inflammatory T cell responses. Here we will discuss key immunological aspects of ImmTAC mechanism of action and therapeutic activity in advanced melanoma patients.

11:05 What Intratumoral Tregs Eat Makes Them Strong, but Vulnerable: A New Metabolic Intervention for Cancer Immunotherapy

Ho Ping-ChihPing-Chih Ho, PhD, Assistant Professor, Oncology, University of Lausanne

Targeting intratumoral Tregs is a desirable strategy to reprogram the tumor microenvironment for cancer immunotherapy. However, the systemic impairment and destruction of Tregs caused by current strategies limit its application in cancer treatment. Here, I will discuss how intratumoral Tregs support their survival and suppressive functions in the tumor microenvironment via metabolic adaptation and how targeting this metabolic machinery can lead to selective destruction of intratumoral Tregs.

11:35 Tertiary Lymphoid Structures and Tumor-Specific B Cell Response in Gastrointestinal Cancer

Schloβer__HansHans Schlößer, MD, Principal Investigator, Cologne Translational Immunology, Center for Molecular Medicine Cologne

Tumor-infiltrating lymphocytes (TILs) are correlated to prognosis of several kinds of cancer. Most studies focused on T cells, while the role of tumor-associated B cells (TABs) has only recently gained more attention. TABs are highly differentiated and frequently organize in tertiary lymphoid structures. Tumor-specific B cell response as well as composition and spatial distribution of TABs in gastrointestinal cancer will be discussed in the context of emerging immunotherapies.

13:05 Using Phage Display of Antibodies as a Discovery Tool to Identify Disease-Related Targets

Kristensen_PeterPeter Kristensen, PhD, Head of Section of Biotechnology, Associate Professor, Department of Chemistry and Bioscience, Aalborg University

Large repertoires of recombinant antibodies displayed on filamentous bacteriophage can be applied as a discovery tool to identify new disease-related targets. As selection of recombinant antibodies can be performed on single cells in heterogeneous population or tissue sections, the ability to identify posttranslational modified targets, or targets where localization is changed, is improved. Here a few examples will be given as to how recombinant antibody technology is used as a discovery tool in cancer.

13:35 Microsphere Affinity Proteomics: High Throughput Deconvolution of Antibody Libraries

Lund-Johansen_Fridtjof_CREDIT_PHOTOGRAPHER_Terje_HeiestadFridtjof Lund-Johansen, MD, PhD, Senior Scientist, Department of Immunology, Oslo University Hospital, Norway

Microsphere Affinity Proteomics (MAP) is a versatile platform to study antibody-antigen interactions by flow cytometry. MAP antibody arrays provide means to probe 4,300 antibodies for binding of proteins from complex samples, such as cell and tissue lysates, while MAP arrays with 12,000 full-length human proteins open new possibilities for assessing antibody specificity and detection of autoantibody targets.

14:05 Targeting Disease-Specific Inflammatory Stimuli: Novel Immunotherapies to Prevent or Reinforce Autoimmunity

Midwood_KimKim Midwood, PhD, Professor, Kennedy Institute of Rheumatology, University of Oxford

Whilst immune defense against cancer is a key determinant of tumor elimination, mistargeted inflammation directed against healthy tissue underpins autoimmune disease pathogenesis. Investigating how regulatory control over endogenous triggers of inflammation goes awry in rheumatoid arthritis, and how tumors exploit these mechanisms to evade immune surveillance, has led to the development of new therapies designed to prevent autoimmune joint destruction in arthritis and to re-educate anti-tumoral immunity.

14:35 Functional Anti-Tumor Antibodies from Cancer Patients

Emerling_DanielDaniel Emerling, PhD, Senior Vice President, Research, Atreca, Inc.

By analyzing monoclonal antibodies derived from plasmablast IgG sequences of non-progressing cancer patients, we have identified more than 1,400 antibodies that bind to non-autologous human tumor tissue. These data, along with binding data from both human and mouse tumor cell lines, suggest that these antibodies target public tumor antigens. Among these antibodies, we have antibodies that show anti-tumor functional activity in vitro and that show activity in mouse tumor models. Our research on mechanism of action reveals potential for novel immuno-oncology targets and treatments.
