TCR Sequencing: Transforming the Diagnosis and Care of Cutaneous T cell Lymphomas
  • Rachael Clark, MD, PhD - Shing-Yiu Yip and Cecilia M. Hepp Associate Professor of Dermatology, Harvard Medical School

Cutaneous T cell lymphomas are a heterogeneous collection of non-Hodgkin's lymphomas that arise from T cells tropic for the skin. High throughput TCR sequencing (HTS) is transforming the care of patients with these cancers.  HTS provides rapid and accurate diagnoses, allows direct measurement of malignant T cells in skin before and after therapeutic interventions and discriminates patients with indolent lymphomas from those that will develop progressive, often lethal disease.

Benralizumab, A Monoclonal Antibody Engineered for Enhanced NK-cell Mediated Eosinophil Depletion
  • Badrul Chowdhury, M.D., Ph.D - Senior Vice President, R&D, and Respiratory, Inflammation and Autoimmunity iMED Head, Medimmune

Eosinophilia in patients with asthma correlates with increased exacerbation susceptibility. Benralizumab is a humanized, monoclonal antibody that targets the IL-5 receptor alpha antigen on eosinophils. Afucosylation of benralizumab enhances antibody-dependent cell-mediated cytotoxicity activity resulting in potent and rapid depletion of eosinophils. Benralizumab has demonstrated clinical efficacy in two pivotal Phase III trials, resulting in reductions of asthma exacerbations.

The library can be used to discover VHHs in an industry standard phage display format, as well as through our proprietary CIS display selection process. In this talk, we will briefly discuss the benefits this library design brings, and illustrate some of the unique benefits of VHH technology over conventional antibodies. Using recently generated new data, we will demonstrate how the unbiased diversity enables rapid and resource efficient isolation of developable VHH leads to membrane proteins. Examples will include the use of the library in a phenotypic screening 'whole cell' panning project, as well as in selections to isolated membrane proteins complexes.

Immunogenicity in Biotherapeutic Development
  • Valerie Quarmby - Staff Scientist and Director, BioAnalytical Sciences, Genentech, A member of the Roche Group, USA

Every biotherapeutic has the potential to elicit unwanted immune responses in treated patients. These may compromise safety or efficacy; if there is a profound impact on the drug's risk/benefit profile, immunogenicity can even cause termination of drug development. This talk will review immunogenicity and discuss approaches to risk mitigation.

Decoding Ligand Receptor Interactions
  • Bernd Wollscheid, PhD - Professor, Chemical & Systems Biology, Institute of Molecular Systems Biology and Department of Health Sciences and Technology (D-HEST), ETH Zurich

Cellular responses depend on the interactions of extracellular ligands, such as nutrients, growth factors, or drugs, with specific cell-surface receptors. The sensitivity of these interactions to non-physiological conditions makes them challenging to study using in vitro assays. HATRIC-based Ligand Receptor Capture technology (HATRIC-LRC) enables antibody target validation within the native nanoscale organization of the surfaceome.

Post Hoc Assessment of the Immunogenicity of Bioengineered Factor VIIa Demonstrates the Use of Preclinical Tools
  • Kasper Lamberth, PhD - Principal Scientist, Screening & Bioassay Technology, Novo Nordisk A/S

The development of a bioengineered recombinant Factor VIIa (rFVIIa) analog was discontinued after phase 3 trials due to development of ADAs. The FVIIa analog has three mutations compared to the unmodified parent molecule rFVIIa. By using computational and experimental methods we demonstrate that the observed ADAs could have been elicited by neo-epitopes in the engineered-protein

Pathology from the Molecular Scale on Up
  • Ahmet Coskun, Ph.D. - Instructor, Rad/Molecular Imaging Program, Stanford University School of Medicine

High parameter single cell analysis has driven deep understanding of immune processes.  Using a next-generation single-cell "mass cytometry" platform we quantify surface and cytokine or drug responsive indices of kinase target with 45 or more parameter analyses (e.g. 45 antibodies, viability, nucleic acid content, and relative cell size).  Similarly, we have developed two advanced technologies termed MIBI and CODEX that enable deep phenotyping of solid tissue in both fresh frozen and FFPE formats (50 - 100 markers). Collectively, the systems allow for subcellular analysis from the 70nm resolution scale to whole tissue in 3D. I will present evidence of deep internal order in immune functionality demonstrating that differentiation and immune activities have evolved with a definable "shape".  Further, specific cellular neighborhoods of immune cells are now definable with unique abilities to affect cellular phenotypes-and these neighborhoods alter in various cancer disease states.   In addition to cancer, these shapes and neighborhoods are altered during immune action and "imprinted" during, and after, pathogen attack, traumatic injury, or auto-immune disease.  Hierarchies of functionally defined trans-cellular modules are observed that can be used for mechanistic and clinical insights in cancer and immune therapies.

Emerging Approaches to Modulate Receptor Function in Stem Cells
  • Rami Hannoush, PhD - Principal Scientist & Group Leader, Genentech

The Frizzled (FZD) 7 receptor (FZD7) is enriched in LGR5+ intestinal stem cells and plays a critical role in their self-renewal. This presentation will highlight our group's peptide drug discovery approaches for targeting specific FZD isoforms, providing new structural insights into the molecular arrangement of members of the FZD receptor family and their mode of regulation. The peptides discovered modulate stem cell function in intestinal organoids and can be utilized as probes to further study the role of individual FZD receptors in cancer stem cell biology.

Emicizumab Case Study: A Risk Mitigation Practice of Immunogenicity and Its Clinical Relevance
  • Shuichi Chiba, PhD - Department Manager, Safety Assessment, Chugai Pharmaceutical Co. Ltd.

A case of de-immunization practice during the molecular designing process of an engineered bispecific antibody, emicizumab, will be presented. Although the lead molecule shows low immunogenic potential in in silico analysis, our in vitro assay suggested the higher possibility of immunogenicity. The final candidate has been selected after several trials of in vitro assay and shows low immunogenicity in the clinical trials

Secukinumab Demonstrates Significantly Lower In vitro Immunogenicity Potential Compared to Ixekizumab and Other Therapeutic Antibodies
  • Frank Kolbinger, PhD - Executive Director, Novartis Pharma AG

Secukinumab, a fully human monoclonal antibody that selectively neutralizes IL-17A, has been shown to have significant efficacy in the treatment of moderate to severe plaque psoriasis (PsO) demonstrating a rapid onset of action and sustained responses with a favorable safety profile. Biotherapeutics, including monoclonal antibodies (mAbs), can be immunogenic, potentially generating anti-drug antibodies (ADAs) that can cause hypersensitivity and/or compromise efficacy. Clinically, secukinumab has been shown to have a low rate of ADAs in a pooled analysis of Phase 3 trials. Using in vitro techniques, we wanted to understand the potential reasons for this low clinical immunogenicity incidence rate. We therefore analyzed peptides presented by antigen-presenting cells and T cell precursor frequencies for 4 different mAbs: secukinumab, ixekizumab, adalimumab and ustekinumab and observed that secukinumab demonstrated a low in vitro immunogenicity potential compared with other therapeutic antibodies used to treat PsO patients. Results from these in vitro studies will be presented along with a more detailed evaluation of the T-cell peptide specificities of antibody-reactive T-cell clones.
