Cambridge Healthtech Institute’s 15th Annual

Recombinant Protein Therapeutics

Fusion Proteins and Beyond

January 14-15, 2019

 

Cambridge Healthtech Institute’s 15th Annual Recombinant Protein Therapeutics conference presents the latest developments in non-antibody therapeutics from international leaders. The conference focuses on the varying designs of fusion protein-based therapeutics and the latest data from R&D to post-approval, including Case Studies. By combining modular building blocks that can reach targets not accessible to antibodies, Fusion Protein Therapies possess advantages over antibody-based therapies; their customizable functionality translates into lower patient dosing, reduced production costs, and improved product homogeneity. This conference will demonstrate how these molecules are being engineered to form more efficacious therapeutics that offer specificity with enhanced stability and longer half-life.

10:45 Proinsulin-Transferrin Fusion Protein to Overcome Insulin Resistance

Shen_Wei-ChiangWei-Chiang Shen, PhD, John A. Biles Professor, Pharmacology and Pharmaceutical Sciences, University of Southern California School of Pharmacy

We have previously shown that proinsulin-transferrin fusion protein (ProINS-Tf) is a highly liver-targeted and long-lasting insulin analog for the treatment of diabetes in mouse models. Recently, we have found that the liver-activated ProINS-Tf, due to simultaneous binding to both transferrin and insulin receptor, can overcome insulin-resistance in cell cultures and in NOD mice. ProINS-Tf can serve as a model of insulin analogs for treating insulin-resistance in diabetes and other diseases.

11:15 IL-DR2 Fc Is a Novel Regulator of Immune Homeostasis and Inducer of Antigen-Specific Tolerance

Miller_StephenStephen D. Miller, PhD, Judy Gugenheim Research Professor, Director, Interdepartmental Immunobiology Center, Microbiology-Immunology, Northwestern University Medical School

ILDR2 is a member of the Ig superfamily and has a putative role in pancreatic islet health and survival. We recently found a novel role for ILDR2 in delivering inhibitory signals to T cells. ILDR2-Fc displays a unique mode of action, combining immunomodulation, regulation of immune homeostasis, and re-establishment of Ag-specific immune tolerance via induction of regulatory T cells. These findings support the potential of ILDR-Fc as a promising therapeutic approach for the treatment of autoimmune diseases.

11:45 xB3 Platform Delivers a Protein-Based Interleukin 1 Receptor Antagonist across the BBB and Ameliorates Neuropathic Pain in a Preclinical Model

Tian_Mei_MeiMei Mei Tian, PhD, Vice President and Head, External Research, Bioasis Technologies, Inc.

Utilizing a 12 amino-acid peptide, xB3, we have shown improved brain delivery of antibody payload. xB3-antibody fusion demonstrated similar plasma kinetics to control antibody, however, with significantly increased brain exposure for the duration of the study. In a neuropathic pain model, fusion to interleukin-1receptor antagonist is able to induce significant and durable analgesia following peripheral administration. These data demonstrate the utility of xB3 in delivering therapeutic levels of drug to the brain.

2:05 Antibody-Cytokine Fusion Proteins Targeting Tumor Associated Antigens for the Treatment of Malignancy

Morrison_Sherie Sherie Morrison, PhD, Distinguished Research Professor, Microbiology, Immunology and Molecular Genetics, University of California, Los Angeles

Many cytokines have anti-tumor efficacy, however, their utility for treating malignancy is often limited by toxicities that are dose limiting. To address this problem, we have genetically fused cytokines to antibodies that recognize tumor-associated-antigens. Among other things, we have used this strategy to target interferons to tumor cells using anti-CD20 and anti-CD138 specific antibodies. We have found these antibody fusion proteins effective in the treatment of both lymphoma and myeloma.

2:35 Optimization of a Bispecific Anti-CD3 Antibody-Folate Conjugate for the Treatment of Ovarian Cancer

Harun Rashid, PhD, Senior Principal Scientist, Molecular Technology, Ambrx, Inc.

Here, we report the optimization of an anti-CD3 Fab-folate conjugate that targets cytotoxic T cells to folate receptor positive (FR+) tumor cells for optimal efficacy, reduced toxicity and optimal pharmacokinetic (PK). The optimized conjugates showed potent and selective in vitro activity, good serum half-life, and potent in vivo activity in xenograft mouse models. This semi-synthetic approach shows promise for the generation of additional anti-CD3 bispecific agents using small molecule ligands selective for other TAAs.

4:30 Advancing Targeted Protein Therapeutics (TPTs) in Clinical Drug Development

Cizeau_JeannickJeannick Cizeau, PhD, Director, Research, Sesen Bio, Inc.

The design and differential mechanism of action of Sesen’s TPTs comprising an antibody fragment genetically fused to a protein toxin versus traditional small molecule drugs used for ADCs will be discussed. Data from an ongoing pivotal Phase III trial in non-muscle invasive bladder cancer will be presented to illustrate the rationale design approach of TPTs for use in clinical oncology.

5:00 Hexavalent Agonists Targeting Co-Stimulatory Receptors of the TNFR-Superfamily for Cancer Immunotherapy

Christian Gieffers, PhD, Vice President, Analytics/Protein Chemistry, Apogenix AG

Apogenix’s novel hexavalent TNFR-SF agonists (HERA) are developed for the immunologic treatment of cancer. The construction principle is based on trivalent molecular mimics of the TNF-SF Receptor binding domains fused to a dimerization scaffold. The resulting hexavalent fusion proteins are potent TNFR-SF agonists that activate distinct immune cell populations. HERA compounds show single-agent anti-tumor activity and provide exciting opportunities for combinatorial treatment.

5:30 Prospects of PASylation for the Design of Protein Therapeutics and Tumor Imaging Reagents

Binder_UliUli Binder, MSc, CTO, XL-protein GmbH

PASylation®, the genetic fusion or chemical coupling of proteins or peptides with conformationally disordered polypeptides comprising the L-amino acids Pro, Ala, and/or Ser (PAS), is a superior way to enlarge the hydrodynamic volume and to extend plasma half-life. Further to illustrating the fundamental concepts of PASylation technology, this presentation will highlight a first proof-of-concept tumor imaging study in a human patient.

8:50 Engineered FcRn Binding Fusion Peptides for Half-Life Extension

Boyles_Jeffrey Jeffrey Boyles, MSc, Research Scientist, Protein Optimization, Eli Lilly and Company

The therapeutic potential of small proteins, peptides, and mAb derived domains can be significantly limited by their rapid peripheral clearance in vivo. We show that small FcRn binding peptides (FcRnBPs) fused to the N- and/or C-termini of a Fab can significantly improve the pharmacokinetics of the protein in cynomolgus monkeys. The extent of this benefit can be modulated by number, structure, and post-translational modifications of the FcRnBP.

9:20 Developing a Conjugation-Based Multivalent Ab Format

Ellerman_Diego Diego Ellerman, PhD, Principal Scientific Researcher, Protein Chemistry, Genentech, Inc.

A multivalent Ab format based on protein conjugation was developed (TRAC) to enable a plug and play system for the rapid screening of new multispecific/multivalent Abs. The building blocks used are mAbs and Fabs with good expression yields and stability. A conjugation site was identified that supports high conjugation rates, an efficient process and a stable molecule. We provide examples of different TRACS that require concurrent binding of all Fabs for their biological activity.

11:00 Therapeutic Fusion Proteins Targeted to Blood and Vascular Cells

Muzykantov_Vladimir Vladimir Muzykantov, MD, PhD, Professor, Pharmacology, The Center for Translational Targeted Therapeutics and Nanomedicine (CT3N) and Systems Pharmacology, Perelman School of Medicine, University of Pennsylvania

Conjugating biotherapeutics including thrombomodulin with scFv to blood cells boosts bioavailability, while conjugating with scFv binding to endothelial determinants provides endothelial targeting. Selecting determinants that permit fusion cooperation with cofactors boosts the effect. Further, dual targeting of two fusions delivering collaborative cargoes to adjacent epitopes maximizes binding and effect. Vascular targeting of anti-thrombotic and anti-inflammatory fusions affords beneficial effects unrivaled by untargeted counterparts in animal models of acute lung injury, ischemia-reperfusion and sepsis.

11:30 Affibody-Based Next-Generation Therapeutics

Stefan Ståhl, PhD, Professor and Head, Protein Science, KTH Royal Institute of Technology

Affibody molecules [Ståhl et al, Trends Biotechnol. 8, 691-712, 2017] have been investigated extensively for medical imaging applications and been found safe and efficacious in humans (currently in late-stage clinical evaluations for imaging of HER2-positive breast cancer). This has paved the way for development of affibody-based therapeutics. A couple of projects are now in clinical testing, e.g., for plaques psoriasis, and several are in preclinical evaluation, e.g., targeting cancer and neurodegenerative disorders.
