2:05 New Methods and Antibody Formats for Achieving Exceptional Specificity

Shohei_KoideShohei Koide, Ph.D., Professor, Biochemistry and Molecular Biology, University of Chicago

Creating affinity reagents that discriminate subtle chemical differences, such as post-translational modifications, remains a major challenge, although the problem of achieving high affinity is essentially solved. We have engineered antibody and non-antibody reagents with high specificity, including those that cleanly discriminate the difference of a methyl group, arguably the smallest difference in protein antigens. A surprising mechanism underlying their exquisite specificity led to new antibody formats suitable for achieving exceptional specificity.


2:45 Strategies and Applications for Epitope Mapping

Caroline_ColleyCaroline Colley, Ph.D., Senior Scientist, Antibody Discovery and Protein Engineering, MedImmune

There are a variety of epitope mapping methods with a range of different applications in antibody discovery. These range from low-resolution approaches, such as competition assays, which enable selection of antibodies recognizing different regions of the target, through to high-resolution X-ray crystallography, which can contribute to defining mechanism of action. This talk outlines epitope mapping approaches at MedImmune, and using case studies, highlights their application for drug discovery.

5:00 Epitope Diversity Evaluation in the Early Screening Funnel

Alexander Ivanov, Ph.D., Senior Scientist, Head, Biomolecular Interaction Group, AbbVie Bioresearch Center

Generation of large and diverse pools of biologic molecules may be critical to improve success in Biologic drug discovery. Properly designed high throughput screening at a very early stage could be important to secure competitive advantage. The talk will provide case study examples and review of the role and use of emerging and existing technologies for early epitope diversity screening that could help in selecting a drug candidate, save time and resources on assay development, enrich institutional knowledge and potentially inform intellectual property considerations.

8:35 Biologic and Antibody Approaches to Undruggable Intracellular Targets

David_ScheinbergDavid A. Scheinberg, M.D., Ph.D., Vincent Astor Chair, and Chairman, Molecular Pharmacology Program, Sloan Kettering Institute

Most proteins and oncogenic drivers are not druggable currently with small molecules. MHC presentation of peptide fragments of these critical proteins on the cell surface allows recognition and killing of target cells by TCR’s on T cells after vaccination or by use of TCR mimic antibodies. Several examples with multiple formats showing selectivity and cytotoxicity to several cancer cell types will be demonstrated.

9:05 Targeting Cell Surface Antigens with a Novel Therapeutic Antibody Concept

Paul_ParrenPaul W.H.I. Parren, Ph.D., Senior Vice President and Scientific Director, Genmab

IgG molecules can form ordered hexamers upon binding to membrane-bound antigens. We developed a novel therapeutic antibody platform inspired by this natural mechanism. By introducing specific mutations in the Fc domain, we developed the HexaBody technology, a novel antibody format that shows enhanced hexamerization upon target binding on a cell surface, while remaining fully monomeric in solution. This presentation describes therapeutic applications of HexaBody for the treatment of cancer.

Schrodinger Biologics9:35 Computational Advances in Antibody Design: Toward Improved Optimization and Selection

Pearlman_DavidDavid Pearlman, Ph.D., Senior Principal Scientist, Schrödinger

Recent computational advances hold significant promise both for improved prediction of antibody structure from sequence, and for the ability to precisely calculate physically relevant properties such as affinity and stability. When combined with additional theoretical approaches to identify liabilities, we can use these tools to variously optimize a lead antibody candidate and triage among multiple potential leads.

10:50 Novel Insights of Engineering Non-Antigen Contact Regions of Factor VIII Mimetic Bispecific Anti-Factor IXa/Factor X IgG Antibody

Yuri_TeranishiYuri Teranishi, M.E., Research Scientist, Antibody Engineering Group, Discovery Research, Chugai Pharmaceutical Co., Ltd.

ACE910 is a humanized anti-factors IXa and X bispecific IgG4 antibody that places two factors into proximity and mimics factor VIII function for the treatment of hemophilia A. We have evaluated the effect of modification of non-antigen contacting regions on the biological activity of FVIII mimetic bispecific antibody. Some novel insights from this study unique to our bispecific antibody will be presented.

11:20 Antibody Engineering for Enhanced Ph-Dependent FcRn Interaction

Tilman_SchlothauerTilman Schlothauer, Ph.D., Senior Scientist, Biochemical and Analytical Research, Large Molecule Research, Roche Pharma Research and Early Development (pRED), Roche Innovation Center Penzberg

The human Fc receptor neonatal (FcRn) is responsible for endosomal antibody transport and mediation of antibody half-life. Many approaches of IgG engineering have been tested in the past to increase the binding affinity to FcRn. A possible pitfall of such approaches is the isolated view only at the Fc domain. We observed by the application of several FcRn interaction analyses and antibody engineerings that an antibody needs to be considered as a whole molecule for appropriate pH dependent FcRn engineering.

11:50 Insights into the Molecular Basis of a Bispecific Antibody’s Target Selectivity

Yariv_MazorYariv Mazor, Ph.D., Scientist, Antibody Discovery and Protein Engineering, MedImmune, LLC

Dual targeting is thought to enhance biological efficacy, limit escape mechanisms, and increase target selectivity via a strong avidity effect mediated by concurrent binding to both antigens on the surface of the same cell. However, factors that regulate the extent of target selectivity are not well understood. We show that dual targeting alone is not sufficient to promote efficient target selectivity, and report the substantial roles played by the affinity of the individual arms, overall avidity and valence.

2:05 Antibody Discovery Against GPCRs Using Yeast Antibody Display Technology

Abhishek_DattaAbhishek Datta, Ph.D., Scientist II, Drug Discovery, Biogen

G-protein coupled receptors (GPCRs) are membrane proteins that are important drug targets. The development of therapeutic antibodies against them has been challenging. We have employed multiple strategies to identify antibodies against a Class A GPCR. Here we present selection strategies that have enabled identification of antibodies using the Adimab yeast antibody discovery and optimization platform. Functional characterization of these antibodies and their potential use as a therapeutic in immunological disorders will be discussed.

2:35 Engineering Ion Channels for Structural Studies and Ligand Discovery

Susmith Mukund, Senior Research Associate, Genentech, Inc.

3:05 Antibody-Mediated Blockade of Human Orai1 Inhibits T Cell Activation in vitro and in vivo

Stefan Zahn, Ph.D., Principal Scientist, Antibody Technology, Novo Nordisk A/S

Ion channels are widely expressed on cells and tightly regulate the flow of ions between the extracellular and the intracellular environment. Dysregulation has been linked to pain, epilepsy and even autoimmune inflammatory diseases. We will present our recent work on targeting T cell-specific ion channels like CRAC by antibodies inhibiting T cell activation in vivo and in vitro.

3:35 Refreshment Break in the Exhibit Hall with Poster Viewing

4:30 Targeting Tumor Selective Cell Surface Antigens Using Designer Antibodies

Madan_KatragaddaMadan Katragadda, Ph.D., Senior Principal Scientist, Pfizer, Inc.

Potent novel means of therapeutic intervention utilizing immune cell retargeting and antibody-drug conjugates necessitates tumor selective targets owing to their extremely high potent nature. Several strategies have evolved in the past decade to selectively target tumors by either exploiting antigens, antigen complexes and glycoepitopes that are selectively overexpressed on tumor cells relative to the normal cells or simultaneously targeting two or more antigens using antibody engineering techniques. Examples describing these strategies are presented.

5:00 Challenges in Generating Antibodies to Integral Membrane Proteins

Ramu_SadhukhanRamkrishna (Ramu) Sadhukhan, Senior Group Leader, AbbVie Bioresearch Center Center

Developing therapeutic antibodies against integral membrane proteins is difficult, as GPCRs and ion channels are often expressed at low levels on cell surface and are unstable when purified. Poor quality membrane protein immunogens has led to limited success in generating antibodies that bind native cell surface molecules and remains a bottleneck for membrane protein target validation and monoclonal antibody-based therapeutics. Here, we present antigen preparation and antibody generation against multispanner proteins.
