antibody engineering and design



The 4th Annual Engineering Antibodies conference at PEGS Europe presents the latest antibodies to watch, and explores technologies and new approaches to discover, design and engineer novel modalities and new platforms for existing and challenging targets. The conference will also explore new techniques such as deep sequencing, in silico engineering and gene editing to help further the understanding of the sequence and structure-function of the molecules, and close the gap from bench to clinic.

Final Agenda

WEDNESDAY 20 NOVEMBER

07:45 Registration (Foyer A) and Morning Coffee (Foyer D)

NEW MODALITIES AND PLATFORMS
Auditorium VII

08:30 Chairperson’s Opening Remarks

Janice M. Reichert, PhD, Executive Director, The Antibody Society, and Editor-in-Chief, mAbs

08:35 TriTAC: A Tri-Specific T Cell Engaging Platform for the Treatment of Solid Tumors

Bryan D. Lemon, PhD, Senior Director, Protein Science, Harpoon Therapeutics, Inc.

T cell engagers are protein therapeutics that tether T cells to surface antigens on tumor cells, leading to activation of those T cells and destruction of the tumor. The TriTAC (tri-specific T cell activating construct) technology is designed to optimize the therapeutic window by addressing half-life and stability limitations of pioneering T cell engagers (e.g., bispecific T bell engagers, or BiTEs). HPN424 first entered the clinic in 2018 and is under development for the treatment of metastatic castration-resistant prostate cancer.

09:05 The Making of a Biparatopic Molecule

Garces_FernandoFernando Garces, PhD, Senior Scientist, Biologics Optimization, Amgen

Multispecifc molecules show great promise as a vehicle to boost pharmacokinetic properties such as therapeutic efficacy and controlled toxicity. Biparatopic antibodies, bispecific molecules that recognize two unique and non-overlapping epitopes on the same antigen/target, have been shown to facilitate receptor internalization, promote superior antagonistic effect, among others. Here, we describe the making of a biparatopic molecule that recognizes two distinct domains on our target receptor. Using a structural-guided approach we have designed, generated and demonstrated that these novel bispecific formats can efficiently bind to both epitopes on the same molecule whereas cross-binding is restricted by the insertion of selected linkers.

09:35 RNAntibody® – A Potent mRNA Technology for Antibody Therapies

Lutz_JohannesJohannes Lutz, PhD, Senior Scientist, CureVac

The delivery of genetic information has emerged as a promising alternative to overcome drawbacks associated with the use of recombinant proteins in protein therapies. Recently, we demonstrated that a single injection of antibody-encoding mRNA rapidly leads to high neutralizing antibody titers in animals, sufficient to provide fast protection against lethal rabies infection or botulinum intoxication. Additionally, we demonstrated that our RNAntibody technology is able to generate therapeutically effective amounts of antibodies in two different mouse models for malignant diseases.

10:05 An Integrated Approach to Managing Immunogenicity Risk and Optimum Protein Design

Fry_JeremyJeremy Fry, PhD, Director of Sales, ProImmune, Ltd.

11:15 Targeted Thorium Conjugates (TTCs): A New Modality for the Treatment of Cancer Utilizing Alpha Particle-Based Radiotherapy

Cuthbertson_AlanAlan Cuthbertson, PhD, Head of Thorium R&D, TCR, Bayer AS

This talk will cover many preclinical aspects of cancer therapy using tumor antigen specific antibodies for the delivery of alpha particle radiation to tumors. The core elements of targeted alpha therapy will be explained along with a selection of data from in vitro and in vivo models demonstrating the potential of this versatile platform.

11:45 The Contorsbody, a Format for Agonism: Design, Structure, Function

Georges_GuyGuy Georges, PhD, Expert Scientist, Large Molecule Research, Roche Innovation Center Munich

The contorsbody is a novel Ab format designed to achieve receptor dimerization. A hybrid structure combining X-ray diffraction and cryo electron microscopy data reveals a special architecture for this format. Depending on receptor and epitope, regular IgG antagonist antibody (ligand blocker or dimerization blocker) can be switched into full agonist when transformed into mono-specific bivalent contorsbody. Bispecific contorsbodies can be obtained via the “Knob into Hole” technology so that receptor hetero-dimerization or hetero-clustering can be achieved.

12:15 Preclinical Development of ELN/22, a Novel “Super-Neutralising” Solomer™ Specific for Human TNF-Alpha

Ubah_ObinnaObinna Ubah, PhD, Senior Research Scientist, Biologics Drug Discovery and Protein Engineering, Elasmogen Limited, Aberdeen

TNFα is implicated in a host of chronic autoimmune inflammatory diseases. Therapeutic targeting and subsequent neutralisation of TNFα has demonstrated positive clinical outcomes, however a significant percentage of these patients fail to respond or have their disease satisfactorily controlled with many patients discontinuing treatment due to life-threatening side effects. The ELN/22 drug candidate is an empirically designed novel biologic with a unique mechanism of TNFα neutralisation and delivers a superior efficacy in an in vivo model of polyarthritis. In addition, the ELN/22 has been designed to reduce the risk of ADA and serious side effects development.

12:45 Industrializing IO Therapeutic Discovery Platforms: Multispecifics, Engineered TCRs and CARs

Jana HerschJana Hersch, PhD, Scientific Consultant, Biologics, Genedata

Novel classes of bio-molecules are currently evaluated for their use in cancer immunotherapy.

15:05 KEYNOTE PRESENTATION: Explorations in Antibody Product Discovery

Janine Schuurman, PhD, Corporate Vice President Research & Innovation, Antibody Research & Technology, Genmab

The basis for successful product discovery is a conceptual product idea which integrates scientific information on the biology of the disease and the target (or targets), and a thorough understanding of antibody format opportunities. Nevertheless, empirical screening of different target and antibody format combinations is critical, and often adaptations to initial assumptions are required before a novel product fulfilling the anticipated product criteria is discovered: the antibody fine specificity, combined with the format chosen, can have a huge and not always predictable impact on the functional characteristics of novel antibody product. Examples will be shared and discussed.
