We give an overview of preclinical activity of CEA-TCB and CD20-TCB, two clinical stage T cell bispecific antibodies based on the “2:1” IgG format. In addition, we present combination strategies of these two TCBs with checkpoint inhibitors
and novel targeted costimulatory molecules.
09:35 A Novel Mucin 16 Bispecific T Cell Engaging Antibody for the Treatment of Ovarian Cancer
Alison Crawford,
PhD, Senior Staff Scientist, Oncology and Angiogenesis, Regeneron Pharmaceuticals, Inc.
REGN4018 binds both Mucin 16 (MUC16) and CD3. REGN4018 induced T cell killing of MUC16-expressing tumor cells in vitro in the presence of CA-125. REGN4018 potently inhibited tumor growth in a xenogeneic mouse model, as
well as in immuno-competent mice genetically engineered to express human CD3 and human MUC16. Toxicology studies in cynomolgus monkeys revealed no overt toxicity, supporting clinical evaluation of REGN4018 in patients with advanced ovarian cancer.
10:05 Renmab™ Mouse: A Leading Platform for Fully Human Antibody Generation
Chaoshe Guo Vice President, Global Head of Business Development, Biocytogen
Biocytogen has recently developed RenMab Mouse, a fully human antibody mouse with its entire variable regions replaced by human Ig heavy chain and light chain. The RenMab™ model has also demonstrated a similar immune response to the wildtype
strain as it carries the full human antibody repertoire. Combined with existing inventory of single, double or triple target humanized mouse models, Biocytogen is poised to provide an one-stop solution from target validation to IND application.
10:35 Coffee Break in the Exhibit Hall with Poster Viewing (Rio Pavilion)
11:15 KEYNOTE PRESENTATION: Bispecific Antibodies: Discovery, Development, and Next Generation
Tomoyuki Igawa, PhD, CEO, Head, Research, Global Biologics Leader, Chugai Pharmabody Research Pte. Ltd.
Emicizumab, a humanized anti-FIXa/FX bispecific antibody for hemophilia A, is the first bispecific IgG antibody which was approved by the FDA. Now, many T cell-redirecting bispecific IgG antibodies are being developed. In my presentation, I will
talk about the discovery and development of these bispecific IgG antibodies, and how novel antibody engineering can further improve the properties of these molecules.

Tariq Ghayur,
PhD, Distinguished Research Fellow, AbbVie Bioresearch Center
This will examine the technical challenges of making bi-/multi-specific biologics that have been (or can be) solved, and address the key challenges, namely to design molecules that match the disease biology and meet clinical needs. We are
developing methods and tool molecules to understand the biology of the various aspects of cancer, ranging from the immunity cycle to the design of therapeutic molecules. Examples of these efforts will be discussed.
15:05 Benefits of Chicken-Derived Antibodies for Combination Immunotherapy
Klaus Koefoed, PhD, MSc, Director, Antibody Technology, Symphogen A/S
Development of novel antibodies and more powerful therapeutic combinations for immunotherapy is an intense area of focus. However, difficult and/or conserved targets, finding antibodies with unique functionality, and generating early PoC pose
challenges to the development of novel antibody therapeutics. Symphogen’s approach to discovery and development of potent antibody combinations for cancer immunotherapy using different species, including chicken, will be presented.
Examples from our clinical pipeline will be shown.
15:35 Refreshment Break in the Exhibit Hall with Poster Viewing
16:15 DuoHexaBody-CD37, a Novel CD37-Targeting Bispecific Antibody with a Hexamerization-Enhancing Mutation, Demonstrating Superior Preclinical Activity Against Malignant B Cells in vitro,
ex vivo, and in vivo
Esther Breij, PhD, Senior Director, Translational Research, Genmab B.V.
DuoHexaBody™-CD37 is a bispecific antibody with a hexamerization-enhancing mutation that targets two different epitopes on CD37. DuoHexaBody-CD37 was designed to induce highly potent cytotoxicity of B cells in a variety of B cell malignancies
through enhanced complement-dependent cytotoxicity (CDC) and other Fc-mediated effector functions. Here we will present studies on the rational design, mechanism of action, and pre-clinical efficacy of DuoHexaBody-CD37.
16:45 Towards RNA-Based Cancer Immunotherapy: Advances in the Development of mRNA Encoded Therapeutic Antibodies
Ursula Ellinghaus, PhD, Scientist, Bispecific Antibodies, BioNTech RNA Pharmaceuticals GmbH
BioNTechs RiboMAB® platform, based on in vitro-transcribed non-immunogenic mRNA encoding for a variety of antibodies, is circumventing the production challenges and manufacturing cost of protein-based
monoclonal antibodies. Systemic administration of RiboMABs formulated in LNPs results in sustained antibody levels and elimination of advanced tumors in mice as efficient as the corresponding purified antibody. Given the feasibility and
safety of RiboMABs, we created an exciting platform technology for cancer immunotherapy.
17:15 Anticalin Proteins and Their Application in Respiratory Disease
Christine
Rothe, PhD, Vice President, Discovery & Alliance Management, Pieris Pharmaceuticals GmbH
Anticalin® proteins are based on human lipocalins and can be formulated as inhalable biologics, allowing local delivery to the lung. This was demonstrated with AZD1402/PRS-060, an IL-4Ra antagonist that Pieris is developing in collaboration
with AstraZeneca for the treatment of moderate-to-severe asthma. A first-in-human study has revealed a promising clinical profile. The ability to generate bi- and multi-specific Anticalin proteins offers the potential to address more than
one target in a disease pathway and thus improve efficacy and/or broaden the patient population for a range of respiratory diseases.

08:30 Chairperson’s Remarks
Tariq Ghayur, PhD, Distinguished Research Fellow, AbbVie Bioresearch Center
08:35 PD-1 x LAG-3 (MGD013) and PD-1 x CTLA-4 (MGD019): Two Clinical-Stage DART® Molecules Designed to Simultaneously Block Two Checkpoint Pathways
Alexey Berezhnoy, PhD, Scientist, Cell Biology & Immunology, MacroGenics, Inc.
Tumor-infiltrating lymphocytes frequently co-express multiple immune checkpoint receptors, whose co-blockade provides additional benefits in immunotherapy. Here we applied a bispecific platform to increase stringency and specificity of immune
checkpoint co-blockade. Two clinical-stage bispecific DART molecules, PD-1 x CTLA-4 (MGD019) and PD-1 x LAG-3 (MGD013), will be discussed in this presentation, including format selection, preclinical pharmacology, IND-enabling studies,
and clinical trial design.
09:05 A Novel, Monovalent Tri-Specific Antibody-Based Molecule that Simultaneously Modulates PD-L1 and 4-1BB Exhibits Potent Anti-Tumoral Activity in vivo
Stefan Warmuth, PhD, Head, CMC, Therapeutic Program Lead, Numab Therapeutics AG
Targeting PD-L1 and 4-1BB with multi-specific antibodies holds the promise of increased potency, while improving the safety profile compared to combination therapy. Numab develops a molecule that potently blocks PD-L1/PD-1 signaling and elicits
further T cell activation through its costimulatory domain solely in the proximity of cells that overexpress PD-L1. Preclinical data show efficacy on tumor growth in combination with an enhanced intratumoral CD8+ T cell activation when
compared to the combination of the PD-L1 and 4-1BB modalities.
09:35 Development of a Novel Bi-Functional Fusion Protein Platform (Agonist Redirected Checkpoint or ARC) for Cancer Immunotherapy
George Fromm, PhD, Vice President, Research & Development, Shattuck Labs, Inc.
The ARC platform was developed to solve the challenge of incorporating immune-checkpoint blocking functional domains and tumor necrosis factor (TNF) superfamily agonists (OX40, CD40, 4-1BB, etc.) into single therapeutics. This was achieved
by engineering hexameric TNF ligands, which uniquely activate TNF receptors compared to mono- or di-valent antibody-based approaches. The ARC platform has provided a means to unlock this family of costimulatory molecules, which is currently
being evaluated in a clinical study.
10:05 Next-Generation Reporter Technologies for Immunotherapy Discovery and Potency Testing
Jamison Grailer, Senior Research Scientist, Research & Development, Promega Corporation
Immunotherapy strategies, including immune checkpoint monoclonal antibodies (mAbs), bispecific molecules, and chimeric antigen receptor T (CAR T) cells, are promising new approaches for treating cancer, autoimmunity, and other diseases. A
major challenge in immunotherapy drug development is access to quantitative and reproducible functional assays for screening (e.g. TCR screening), measurement of target cell-specific killing, and potency testing. Here we will present a
variety of next-generation reporter technologies to address these needs in the context of mAb-mediated ADCC, bispecific molecules, and TCR-mediated cell therapies.
10:35 Coffee Break in the Exhibit Hall with Poster Viewing (Rio Pavilion)
11:15 Unbiased Functional Screening of Large Bispecific Antibody Panels to Unlock Novel Biology
Pieter Fokko van Loo, PhD, Director, Oncology-Immunology, Merus N.V.
The Biclonics® technology platform leverages the natural human IgG1 format; enabling high throughput functional screening to discover drug candidates with excellent anti-tumour properties. The discovery of two clinical stage pipeline candidates
will be discussed that highlight the power of this functional screening approach: MCLA-117, a CLEC12AxCD3 T cell engaging antibody for acute myeloid leukemia and MCLA-145, CD137xPD-L1 bispecific antibody that recruits and supercharges
tumor infiltrating lymphocytes.
11:45 An International Collaborative Study to Establish a 1st Reference Panel for Cytokine Release Assays
Sandrine Vessillier, PhD, Principal Scientist, Head, Immunotoxicology Cellular Immunology, Biotherapeutics, National Institute for Biological Standards and Control, UK
Cytokine release assays (CRAs) are key for hazard ID of immunotherapeutics, such as cytokine release syndrome (CRS). To gain a better understanding of the comparability between different CRA formats, NIBSC recently produced a panel of lyophilised
recombinant antibodies known to induce CRS of different intensities and three isotype-matched negative controls. The relative potency of these antibodies to stimulate cytokine release was evaluated in an international collaborative study.
