2:55 Deep Mutagenesis for Integrative Structure Determination, Binding Site Characterization, and Conformational Engineering of Dynamic Membrane Proteins

Procko_EricErik Procko, PhD, Assistant Professor, Biochemistry, University of Illinois at Urbana-Champaign

When the directed evolution of mutant libraries is tracked with deep sequencing, the phenotypes of thousands of sequence variants can be determined simultaneously. This method, known as deep mutagenesis, has been applied in cell culture to dynamic membrane proteins with roles in mental health and immunity, including GPCRs, transporters, an MHC chaperone, and viral immunogens. The mutational landscapes help define ligand-binding sites, inform mechanism, assist engineering, and constrain computational modeling.

3:25 Monoclonality Does Not Mean Monospecificity – Paratope Refinement to Mitigate Antibody Polyspecificity

Finlay_JonnyJonny Finlay, PhD, CSO, Ultrahuman, United Kingdom

Antibodies are well known to become ‘polyreactive’ (randomly sticky) via excess charge or hydrophobicity. We have a much poorer understanding of what causes off-target reactivity to disparate, but selective, targets (polyspecificity). There is also a paucity of understanding in how this drives antibody toxicity. This will show that polyspecificity is an underappreciated phenomenon in therapeutic antibody development, but that these unwanted properties can be fully ameliorated by paratope refinement.

3:55 Rapid Assembly of Diverse Gene Variant Libraries Using Semiconductor Technologies

Irene Song, Scientific Advisor, GenScript USA Inc.

Optimization of therapeutics requires the use of high quality mutant libraries. Traditional methods for library construction suffer from limited control over codons, resulting in poor variant representation. Our advanced oligo synthesis platform allows for precise control over codon usage, creating a diverse and fully represented mutant library, improving screening efficiency.

Vaccinex 4:10 Use of Mammalian Virus Display to Select Antibodies Specific for Complex Membrane Antigens

Ernest Smith, PhD, Senior Vice President & CSO, Vaccinex

We have developed a technology to enable direct incorporation of multipass membrane proteins into the membrane of a mammalian virus. Antigen expressing virus is easily purified for antibody selection. This method does not require any detergents or refolding and produces properly folded protein that is necessary for antibody selection.

4:25 Refreshment Break in the Exhibit Hall with Poster Viewing

5:00 Emerging Technologies to Evaluate Developability and Manufacturability

Beach_AaronAaron Beach, Investigator, Novartis Biologics Center, Novartis Institute for BioMedical Research, Inc.

The diversity and increasing complexity of new protein formats requires a change from former platform approaches often applied for antibodies. The Novartis developability assessment combines information about expression, aggregation propensity, process fit, stability, solubility, physicochemical properties, in vivo fitness and immunogenicity of potential candidates. This integrated approach prior to lead selection provides a thorough, yet resource efficient approach. The presentation will provide an overview about the concept and provide selected case studies.

5:30 Utilization of Throughput-Based Platforms to Identify Optimal Bispecifics

Pefaur_NoahNoah Pefaur, PhD, Senior Scientist, AbbVie

Following entry of the DVD-Ig format into the clinic it has become a preferred format for bispecifics at AbbVie. As with any engineered biologic identification of potent molecules with favorable drug like properties frequently requires engineering and screening to identify optimal lead candidates. Here, we present a throughput-based strategy to increase project probability of success, reduce time spent on lead optimization, and increase the quality of identified leads.

6:00 Creating a New Paradigm for Biotherapeutics: Attributes More Potent than Potency

Toprani_VishalVishal Toprani, PhD, Scientist, Pharmaceutical Development, Alexion Pharmaceuticals, Inc.

The field of biotherapeutics is rapidly advancing into novel molecular formats from traditional antibody-based products. This shift to novel protein modalities will require addressing new types of liabilities and implementing modern technologies to evaluate the risk/benefit profiles of these molecules. This presentation will focus on using DOE approaches and automated high throughput biophysical tools, in combination with automated sample preparation to identify attributes that may overrun the potency selection, predominant in protein engineering.

8:45 Engineering Patient-Derived Anti-HIV Broadly Neutralizing Antibodies for Therapeutic Development

Thomsen_NathanNathan Thomsen, PhD, Senior Research Scientist, Gilead Sciences

Advances in discovery technology have led to the isolation of HIV broadly neutralizing antibodies (bNAbs) with exceptional breadth. These bNAbs hold promise for the treatment or cure of HIV, with many in clinical trials. Evolving alongside the virus within a single individual, HIV bNAbs diverge significantly from the human germline repertoire and present unique engineering challenges. Strategies to identify and mitigate development challenges in HIV bNAbs will be discussed.

9:15 Identification, Characterization & Engineering of Antibodies Directed against Complex Target Molecules

Kunz_ChristianChristian Kunz, PhD, Director, Discovery Alliances & Technologies, MorphoSys AG, Germany

Methods generating highly specific antibodies against classical target molecules, as e.g. receptor tyrosine kinases or cytokines, are routinely established. Antibody compounds inhibiting these classical target classes are widely used in clinical development and as approved therapeutics. Innovative selection strategies have to be applied to broaden target space and bring new target classes, as GPCRs or HLA/Peptide complexes, into clinical development.

9:45 KEYNOTE PRESENTATION: Chemical and Physical Determinants of Drug-Like Monoclonal Antibodies

Tessier_PeterPeter M. Tessier, PhD, Professor, Pharmaceutical Sciences and Chemical Engineering, University of Michigan

Therapeutic antibodies display variable and difficult-to-predict levels of non-specific and self- interactions that lead to various drug development challenges, including abnormally high viscosity and fast antibody clearance. We are developing bioinformatics methods for predicting the overall specificity of antibodies in terms of their relative risk for displaying high levels of non-specific and self-interactions. We will report novel types of chemical descriptors that are strong predictors of antibody specificity.

12:10 pm Just a Specific Target is Not Good Enough to Achieve Desired Effect; The Case of Vedolizumab (Entyvio®)

Pierre Eftekhari, PhD, Founder and CEO, Inoviem Scientific

Vedolizumab an antibody against ITGB7 is used for treatment of IBD. Molecular analysis of 31 IBD outpatients, in a prospective clinical study treated with Vedolizumab, showed that the efficient treatment could only be reached when ITGB7 interacts directly with 4 other proteins forming a signaling complex. In the absence of these proteins despite the presence of ITGB7 no therapeutic effect was observed. A therapeutic target is therefore defined as the presence of primary target within its corresponding signaling complex.

12:25 Session Break

Schrodinger 12:35 Luncheon Presentation: Lead Optimization of Biologics Using Physics-Based Computational Methods

Eliud Oloo, PhD, Senior Principal Scientist, Schrödinger

In this presentation, we will describe how calculated properties derived from 3D structural analyses and simulation through physics-based methods are applied to not only optimize binding affinity and selectivity but also identify and mitigate potential liabilities in the development of biologics. Using such computational strategies to direct experimental focus can result in reductions in cost and timelines.

2:10 Strategies, Considerations and Challenges in Engineering Antibody-Drug Conjugates

Chen-Ni Chin, PhD, Director, Antibody Discovery, Mersana Therapeutics

Antibody-drug conjugates (ADCs) are a growing class of biopharmaceuticals designed to harness the targeting specificity of a mAb by linking it to highly potent drugs for delivery. In this talk we will discuss what it means to make an ADC through engineering the antibody as well as applying novel linker and payload technologies for the optimal pharmacological profile. Case studies will be presented.

2:40 Bispecific Antibodies – A Platform Approach for Generation and Screening in Final Format

Fertig_GeorgGeorg Fertig, PhD, Head, Screening & Functional Assays, Roche Pharmaceuticals, Germany

The generation of bi-functional bispecific antibodies requires the combination of two monospecific binders, which bind to the right epitope of the respective target in the right format. High-throughput generation and screening of such antibodies will be discussed in the context of an effective and robust technology platform, an automated production of bsAb binder-format combination matrices and the format, which defines the function.

3:10 Protein Engineering for Enhanced and Sustained CNS Exposure of Neuro-Therapeutic Antibodies

Smith_BenBenjamin Smith, PhD, Scientist, Biologics Drug Discovery, CNS Delivery, Biogen

The single domain antibody FC5 engages receptor-mediated transcytosis and is a promising BBB carrier. Here the humanization and stability engineering of FC5 and design of FC5 bispecifics with antibodies against neurodegenerative disease targets will be described. Enhanced BBB penetration of the bispecifics in an in vitro BBB model as well as CNS pharmacokinetics in rats and monkeys dosed at therapeutically relevant doses by systemic injections will be shown.

3:40 Screening Tools for Early Prediction of Development and Clinical Success

Souders_ColbyColby Souders, PhD, CTO, Abveris

As industry-wide advancements in antibody drug discovery continue to push toward larger panels of candidates for early-stage characterization, more efficient identification of lead molecules through enhanced screening resolution is required. Integrating tools and methods into the overall characterization workflow enables reliable, high throughput selection of lead candidates more effectively than alternative traditional techniques. Comparisons across platforms, including traditional ELISA, flow cytometry, Octet and in vivo studies will be presented that provide enhanced prediction of downstream development and clinical success.
