This is an exciting time for antibody-drug conjugate developers. With many ADCs moving into later-stage clinical trials, the industry is eagerly anticipating the results from these trials. Some of the lessons learned from earlier trials have already been
applied to new generations of ADC design, helping the industry to overcome the setbacks previously experienced. The industry is now eagerly anticipating data from new pivotal trials in solid tumors, results from trials with new payloads and linkers,
and outcomes from combination therapies.
In this Antibody-Drug Conjugates II: Advancing Toward the Clinic conference, we invite scientists to present their latest clinical and preclinical data, as well as lessons learned to help drive the industry toward clinical success.

1:50 KEYNOTE PRESENTATION: Leveraging Antibody-Drug Conjugates to Eradicate Tumor-Initiating Cells
Alex Bankovich, Ph.D., Senior Director, Head of Late Stage Research, AbbVie Stemcentrx, LLC
Tumor-initiating cells (TICs) will remain controversial until findings in the lab translate into drugs providing clear 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 will explain the drug
development path that we followed to some of our current clinical programs.
2:20 Novel Approaches for Modeling Pre-Clinical Activity of ADCs and Informing Biomarker Strategy
Tony D'Alessio, Ph.D., Research Investigator, Novartis Institutes for Biomedical Research, Inc.
Using PTX mouse clinical trials, we have begun to generate population-based in vivo activity datasets on several emerging ADC programs. By integrating response data with molecular features across these models, we are
building a rich dataset for biomarker analysis. Additionally, we are employing fully syngeneic murine tumor models to profile ADC activity in immune-competent settings and characterized pharmacodynamic changes in the tumor microenvironment to inform
rational combination approaches.
2:50 Predicting Clinical Success of ADCs using a Mechanistic Modeling & Simulation Approach
Alison Betts, Ph.D., Associate Research Fellow, Biomedicine Design, Pfizer
Quantitative modeling and simulation was used to analyze data on 10 ADCs in patient trials or approved for oncology indications. Clinical efficacious dose was predicted from preclinical PK/PD studies and compared with clinical MTD, recommended Phase II
and clinically approved doses. Monte Carlo clinical trial simulations were performed to predict objective response rate. This information can be used to select the best ADC, to optimize clinical trial design and determine likelihood of success versus
clinical standard of care.
3:20 Poster Spotlight
Glypican-3 Specific Antibody-Drug Conjugate for Hepatocellular Carcinoma
Ying Fu, Ph.D., Postdoctoral Fellow, Laboratory of Molecular Biology, National Cancer Institute, National Institutes of Health
Hepatocellular carcinoma (HCC) is the third most common cause of cancer-related death. Glypican-3 (GPC3) is a potential target for HCC. The hypothesis of using anti-GPC3 antibody-drug conjugate to treat HCC patients has not been tested in clinical trials.
Here we report the development of hYP7-PC, a humanized anti-GPC3 antibody conjugated to a highly potent DNA damaging agent through cysteine via protease-cleavable linker. hYP7-PC caused tumor remission in HCC Hep3B xenograft model.
3:50 Refreshment Break
4:20 Relationship between the Mononuclear Phagocyte System and the Pharmacokinetics and Pharmacodynamics of Antibody Drug Conjugates in Patients
William C. Zamboni, Pharm.D., Ph.D., Associate Professor; Director, TOND2I Lab, University of North Carolina at
Chapel Hill
The PKPD of carrier-mediated agents (CMA) and ADC agents are dependent on their recognition and interaction with the mononuclear phagocyte system (MPS) where the conjugated drug is cleared via interactions with the MPS. It is important to evaluate how
mediators, characteristics and function of the MPS affect the PK and PD of ADCs. We will discuss: 1) pharmacologic methods to characterize ADCs ex vivo and in vivo; 2) MPS variability
across patient populations; and 3) relationship between mediators, characteristics and function of the MPS and the PK and PD of ADCs in patients.
4:50 Challenges and Solutions Associated with Bioanalysis of Antibody Drug Conjugates in Support of Clinical Studies
Rafiq Islam, Ph.D., Senior Director, Bioanalytical Services, Celerion, Inc.
Since ADCs are generally complex heterogeneous mixtures of multiple species, these novel therapeutic products present unique bioanalytical challenges. Novel bioanalytical approaches and strategies including a combination of ligand-binding assays (LBA)
and LC–MS-based platforms are needed to overcome challenges unique to ADCs. This presentation will examine the different methodologies such as LBAs and LC-MS/MS methods for the bioanalysis of ADCs using Kadcyla® (ado-trastuzumab emtansine)
as a case study.

2:10 HTI-1511, A Novel Anti-EGFR-ADC, Demonstrates Significant Activity against KRAS- or BRAF-Mutated Tumors of Various Types In Preclinical Studies
Christopher D. Thanos, Ph.D., Senior Director, Biotherapeutics Discovery, Halozyme Therapeutics
We have previously described HTI-1511, an ADC in pre-clinical development that targets EGFR. Here we screened a panel of over 70 tumor cell lines derived from various solid tumor malignancies. Evaluations in several human xenograft tumor models
and patient derived tumor models in mice demonstrated potent tumor regression. These results support further development of HTI-1511 as a possible treatment for EGFR overexpressing tumors, including those with downstream activating mutations
in the KRAS/BRAF pathway.
2:40 Novel Medicines that Exploit Extracellular Protein-Protein Interactions
James R. Prudent, Ph.D., President & CEO, Centrose
The talk will review the development of EDCs to multiple cancer-related targets and describe their extracellularmechanism which resembles necrosis. In addition, data using cynomolgus monkey models will be discussed,
where a CD20-specific EDC was able to eliminate all CD20+ B-cells while having no effect on other cells or tissues. This talk will therefore describe a new level of therapeutic precision that depends on protein-protein proximity and not
simply expression.
3:10 Probody Drug Conjugates for the Treatment of Cancer
Jason Sagert, Ph.D., Senior Scientist II, Oncology, CytomX Therapeutics
Probody™ Drug Conjugates (PDCs) are a class of antibody-based therapeutics that remain in a substantially inert, masked form until activated proteolytically in the tumor microenvironment. This platform allows the targeting of antigens
that are highly expressed on tumor cells with high prevalence across multiple types of cancer regardless of normal tissue expression. Preclinical data supporting the development of PDCs will be presented.
