Cambridge Healthtech Institute’s 6th Annual

Antibody-Drug Conjugates

Next-Gen Engineering

January 15-16, 2019

 

As more Antibody-Drug Conjugates head to market, the next-generation of ADCs looms on the horizon. Next-gen engineering requires designing an optimal antibody, payload, linker and conjugation method while ensuring stability, targeted delivery, and limited off-target effects. Cambridge Healthtech Institute’s Antibody-Drug Conjugates conference will explore the engineering finesse required to achieve the crucial balance between efficacy and safety, thus  leading the way to more potent and targeted molecules. Case Studies and data will be shared that exemplify the ongoing efforts to engineer ADCs, move them into the clinic, and fight cancer along with potentially non-oncological indications.

KEYNOTE PRESENTATION

2:05 Advances in Next-Generation ADCs, Immunotherapies and Combinations in the War against Cancer

Rakesh Dixit, PhD, Vice President and Global Head, Translational Sciences-Biologics Safety Assessment, MedImmune, LLC

In my talk, I will discuss advances in next-generation ADCs that are meeting the challenges; some new, some old. One persistent challenge is mitigating dose-limiting toxicities of ADCs and improving therapeutic index. I will also address next-generation immunotherapies and their combinations, and synergies between ADCs and immunotherapies.

2:45 ADCs with IGN Payload in Hematologic Malignancies

Yelena Kovtun, PhD, Associate Director, Pipeline Research and Development, ImmunoGen, Inc.

Several ADCs with mono-imine containing Indolinobenzodiazepine (IGN) payload entered the clinic recently, including IMGN779 and IMGN632, conjugates targeting CD33 and CD123 respectively. The strategy to select targets in hematologic malignancies, as well as to design optimal antibody, payload and conjugation method for IMGN779 and IMGN632 will be covered in the presentation.

4:30 Transvascular Pumping of ADC into Solid Tumors Boosts Drug Potency and Safety

Jan E. Schnitzer, MD, Director and Professor, Cellular & Molecular Biology, Proteogenomics Research Institute for Systems Medicine (PRISM)

Current ADCs can’t deliver drugs inside solid tumors specifically, rapidly or robustly. Near MTD doses required to drive ADCs passively across endothelial cell barriers are inadequate to unleash drug potency inside tumors. We circumvent this passive transvascular delivery paradigm by generating the first antibody to actively penetrate solid tumors. This enables precision tumor targeting and imaging within one hour, boosts therapeutic indices >100-fold and even eradicates multi-drug resistant tumors at doses well below MTD.

5:00 Antibody-Drug Conjugates Targeting Tumor Stromal Cells

Dimiter Dimitrov, PhD, Director, Center for Antibody Therapeutics, University of Pittsburgh Medical School

Targeting the tumor stromal cells in addition to tumor cells with ADCs is a promising anti-cancer strategy. CD276 and TEM8 are variably expressed in a variety of cancers and to different extents on tumor stromal cells and tumor cells. Both CD276-ADC-PBD and TEM8-ADC-MMAE eradicated large established tumors and metastases and improved long-term overall survival in several different mouse models of cancer. Data for ADCs targeting other cancer-related molecules will also be discussed.

NEXT-GEN ENGINEERING STRATEGIES FOR ADCs

8:15 Chairperson’s Remarks

Shalom Goldberg, PhD, Principal Scientist, Discovery Sciences, Janssen Research & Development/Johnson & Johnson

FEATURED PRESENTATION

8:20 Next-Generation ADCs: Considerations and Examples

Marc Damelin, PhD, Senior Director, Biology, Mersana Therapeutics, Inc.

In this case study, I will discuss key opportunities for the discovery and development of next-generation ADCs as informed by learnings from our collective experience. Topics will include molecular design, preclinical studies and development strategy. In this context, I will highlight the rationale and early data from selected technologies and clinical molecules.

8:50 Conjugated or Engineered Antibodies -- Benefits and Limits of Different Therapeutic Modalities

Stefan R. Schmidt, PhD, MBA, Head, Operations (COO), Bioatrium, AG

During the last decade, we could observe disruptive developments in antibody technologies. On the one hand, a broader understanding of drug conjugates and their optimization could be gained. On the other hand, protein engineering was massively applied to improve critical features of antibodies in general. In this talk, the different strategies will be discussed, comparing their benefits and limits and highlighting recent success stories of both therapeutic modalities in the context of functionality and manufacturing.

Honing In on ADC Targets

10:35 Targeting of Tumor-Initiating Cell-Associated Antigens with Antibody-Drug Conjugates

Alex Bankovich, PhD, Senior Director, Late Stage Research, Abbvie Stemcentrx, LLC

Tumor-initiating cells (TICs) will remain controversial until findings in the lab translate into drugs providing significant clinical benefit to patients. Antibody drug conjugates (ADCs) are a promising class of drugs able to target and reduce the frequency of TICs in patient-derived xenografts. My company has worked to discover TIC phenotypes and to utilize methods well-suited to specifically identify cell surface proteins targetable by specific ADCs. My talk expands on the drug development path we followed and provides some new insights.

11:05 Using Multi-Omics Data and Functional Screens to Select Antibody-Drug Conjugate Targets

Jennifer Hill, PhD, Team Lead, MS & NMR Analytics, National Research Council Canada (NRC)

Antibody drug conjugates (ADCs) are a promising therapeutic class for cancer therapy. We describe our approach to identify new ADC targets, incorporating gene expression data mining and glycoproteomic profiling, followed by in vitro screening through a surrogate ADC assay. Based on these target selection methods, we are producing thousands of monoclonal and single-domain antibodies generated against a variety of cancer-associated targets and screening them for ADC activity, in vitro and in vivo.

11:35 SILAC-Based Proteomics Screen to Select Potential ADC Targets

Julian Andreev, PhD, Senior Staff Scientist, Oncology and Angiogenesis, Regeneron Pharmaceuticals

Rapid constitutive lysosomal internalization of Prolactin Receptor (PRLR) is the mechanism behind PRLR ADC efficacy. By bridging PRLR, or another high turnover protein, Amyloid Precursor-like Protein 2 (APLP2), with surface tumor target HER2 using bispecific antibodies, HER2 lysosomal degradation can be triggered, and HER2 ADC efficacy can be significantly improved. Our study opens up a possibility to exploit high turnover proteins such as PRLR and APLP2 in combination with bispecific antibodies to enhance efficacy of ADCs.

Improving Site-Specific Conjugation, Payloads & Scaffold Engineering

4:00 Chairperson’s Remarks

Yelena Kovtun, PhD, Associate Director, Pipeline Research and Development, ImmunoGen, Inc.

4:05 Development of a Site-Specific Peptide-Antibody Conjugation Platform

Yuan Cheng, PhD, Principal Scientist, Medicinal Chemistry, Amgen, Inc.

We developed a site-specific conjugation platform using cysteine-mutant antibody or protein. In this presentation, we describe the optimization of this platform by changing the disulfide caps to cysteamine, using a mild reducing agent, and monitoring individual reaction steps. The conjugation sites and linkers had a significant effect on conjugation efficiency, biological activity, and pharmacokinetic profiles. The platform allowed efficient SAR studies in a variety of research projects and demonstrated feasibility in multi-gram conjugation.

4:35 Highly Homogeneous Antibody-Drug Conjugates Based on Dual Variable Domains

Christoph Rader, PhD, Associate Professor, Immunology and Microbiology, The Scripps Research Institute

Homogeneous antibody-drug conjugates (ADCs) that use a highly reactive buried lysine residue embedded in a dual variable domain (DVD) format can be assembled with high precision and efficiency under mild conditions and reveal potent and specific tumor cell killing in vitro and in vivo. Building on this DVD-ADC platform, we have developed orthogonal conjugation strategies that enable the loading of two different payloads in a one-pot reaction.

5:05 Antibody PBD Conjugates

Philip Howard, PhD, Senior Fellow, MedImmune, Inc.; CSO, Spirogen, Ltd.

Pyrrolobenzodiazepines (PBDs) have found extensive use in the field of antibody drug conjugates. PBD payloads have been studied in more than 20 clinical trials; currently these trials are dominated by tesirine and talirine payloads. This presentation will focus on the learnings from the clinical studies and development of the next generation of PBD payloads.

5:35 Design, Characterization, and LC/MS/MS Bioanalysis of Protein-Drug Conjugates

Shalom Goldberg, PhD, Principal Scientist, Discovery Sciences, Janssen Research & Development/Johnson & Johnson

Antibody- and other protein-drug conjugates have multiple parameters that can be tailored to increase the therapeutic window. Here we describe the design and characterization of a drug conjugate using the Centyrin alternative scaffold, as well as the development of broadly-applicable methods for in vivo characterization using LC/MS/MS.
