Preclinical Models and Tools in Oncology - Part 1

The selection of appropriate preclinical models based on similarity to human biology and disease genotype and phenotype carries considerable potential to ensure higher predictability of preclinical research. The design and interpretation of first-in-man trials remains a major challenge in the development of novel anticancer agents. Key study design elements such as schedule, escalation strategy, targeted patient population, etc. rely heavily on preclinical data. This situation brings into question the predictability of preclinical tumor models as well as the method of analysis and translation of the results of preclinical studies. It is especially difficult to model for preclinical assessment of cancer immunotherapy, the most actively developing area in oncology, because the need for stimulating the response of the immune system adds to the complexity of preclinical models and the applications. Cambridge Healthtech Institute’s Sixth Annual Preclinical Models and Tools in Oncology aims to bring together preclinical and translational cancer researchers in order to initiate knowledge and opinion exchange around preclinical tumor models, including immunocompetent models, and the strategies for preclinical design and assessment of new cancer therapy and combinations.

Final Agenda

Tuesday, June 13

7:00 am Registration Open and Morning Coffee

KEYNOTE SESSION: STRATEGY AND SCIENCE TO ADVANCE TRANSLATIONAL ONCOLOGY

8:25 Chairperson’s Opening Remarks

Mario Perro, Ph.D., Group Leader, Pharmacology, Oncology, Roche

8:35 Translational Research in Oncology and Immuno-Oncology

Peter_HammermanPeter Hammerman M.D., Ph.D., Global Head, Translational Research, Oncology, Novartis

Drug development in oncology has advanced over the past decade with the demonstration of the effectiveness of both targeted and immunotherapy approaches in patients with a diverse array of cancer types. Going forward it will be essential to nominate and understand therapeutic combinations to achieve high degrees of clinical efficacy while minimizing toxicity. In this presentation I will discuss approaches to biomarker identification to guide the use of small molecules and biologics in the context of an integrated translational research program.

9:05 Non-Clinical Approaches to Predict Single Agent vs. Combination Value and Clinical Development Strategies for Emerging Cancer Immunotherapies

James_SmothersJames Smothers, Ph.D., Senior Director & Head, Discovery, Immuno-Oncology & Combinations DPU, GlaxoSmithKline

Non-clinical research studies historically support preclinical development and regulatory submission satisfaction and provide critical support of early clinical development hypotheses and clinical trial design including managing expectations of single agent efficacy or setting strategic vision for combination value through biology synergies. Moreover, following early clinical development milestones, an experimental medicine requires ongoing translational review of the clinical readouts beyond efficacy which in turn requires additional non-clinical analyses and experimental execution to drive results-based decision making and data-informed design of late stage clinical trials in anticipation and hope of drug approvals. Examples of non-clinical studies to support all of these activities will be reviewed including choice of experimental models and design.

9:35 Stress, Death, Immunity and Cancer Therapy

Lorenzo_GalluzziLorenzo Galluzzi, Ph.D., Assistant Professor of Cell Biology Research, Radiation Oncology, Weill Cornell, Weill Cornell Medical College

Some anticancer agents trigger a form of cell death that can elicit an adaptive immune response. Such an “immunogenic cell death” relies on the activation of key stress responses in dying cells, and the consequent emission of danger signals that alert the organism of a threat. Unfortunately, this process is frequently suboptimal, calling for combinatorial strategies that attempt to restore the full-blown immunogenicity of cell death for therapeutic purposes.

In this talk I will discuss the establishment of humanized mice for cancer immune-therapy and optical imaging of human mirco-environment within humanized mice. I will also discuss approaches and parameters to study cancer immune-therapies within microscopy.

11:20 Human Tissue Based Models in Immune-Oncology.

Svetlana Sadekova, Ph.D., Senior Principal Scientist, Head of Translational Pathology Group, Merck

Rapid advancement of immuno-oncology is creating the need for translational strategies to guide indication selection, understand mechanisms of resistance and identify biomarkers of response. This talk will highlight the importance of understanding human tumor microenvironment and focus on strategies based on utilizing human tissues for pre-clinical and clinical translational research.

11:50 Isolation and Analysis of Tumor-Infiltrating Immune Cell Subpopulations

Olaf HardtOlaf Hardt, Manager, Research & Development, Oncology, Miltenyi Biotec GmbH

Tumor-infiltrating leukocytes (TILs) constitute a fraction of highly complex and variable cell types inside the tumor tissue, complicating the analysis of individual subpopulations. In particular, the reliable detection of rare subpopulations is hampered by the detection limits of downstream assays. By combining optimized and automated tissue dissociation with specific pre-enrichment of TILs, we significantly increased the quality of data obtained from TIL characterization while reducing the overall time of analysis.

CASE STUDIES

1:40 Chairperson’s Remarks

Serena Silver, Ph.D., Senior Investigator, Group Leader, Molecular Pharmacology, Novartis Institutes for BioMedical Research

1:50 Preclinical Development of a Novel Antibody-Directed Nanotherapeutic for Treatment of Solid Tumors

Vasileios_AskoxylakisVasileios Askoxylakis, M.D., Ph.D., Medical Director, Merrimack Pharmaceuticals

Liposomal nanotherapeutics offer several advantages over conventional anti-cancer drugs. Nanotherapeutics are characterized by a prolonged circulation time that leads to higher intratumoral accumulation of their cytotoxic payload and reduced toxicity. MM-310, is an antibody-directed nanotherapeutic designed to exploit the overexpression of EphA2 in tumors in order to deliver a highly effective chemotherapeutic to EphA2-overexpressing cancers.

2:20 Discovery and Characterization of HKT288, a Novel ADC Targeting CDH6 for the Treatment of Ovarian and Renal Cancer

Scott_CollinsScott Collins, Scientist, Novartis Institutes for BioMedical Research Inc

We describe the discovery, optimization and broad in vivo functional characterization of a novel CDH6-targeting ADC. CDH6-ADC was selected based on a multi-factorial lead selection campaign incorporating readouts of cell binding, internalization propensity and in vitro cytotoxicity. An optimal linker/payload pair was chosen based on in vivo profiling including an unbiased, high-throughput PTX clinical trial against a panel of 30 unselected patient derived ovarian xenograft (PDX) models.

2:50 Challenges and Solutions in Subcutaneous Tumor Measurement Studies

Cem_GiritCem Girit, Ph.D., CEO, Biopticon Corporation

Accurate measurement of subcutaneous tumor volume, shape and color often depend on user technique and assumptions about shape. Generally caliper measurements rely on an over-simplistic shape model and a subjective decision of boundary location, which can lead to a more than 40% over-estimation of volume. We present an alternative methodology that circumvents these issues, handles irregularly shaped tumors and yields more information for future studies.


Science Exchange3:05 Initial Results from the Reproducibility Project Cancer Biology

Rachel_TsuiRachel Tsui, Ph.D., Staff Scientist, Science Exchange

EX VIVO MODELS TO COMPLEMENT OR REPLACE IN VIVO MODELING

4:05 Novel Approaches to Cancer Cell Lines Design and Applications

Serena_SilverSerena Silver, Ph.D., Senior Investigator, Group Leader, Molecular Pharmacology, Novartis Institutes for BioMedical Research

Growth of cancer cells in 2D format has been a workhorse of the cancer research world, enabling high throughput biology endeavors to identify new targets and new drugs. However, it is clear that we are sampling only a subset of cancer complexity in these models, for example by comparison of genomic characterization between primary tumors, xenografts, and cell lines grown in 2D. I will discuss our efforts to use methods such as co-culture and high content imaging of cells grown in 3D systems to assess if these can indeed “fill the gap” and advance oncology drug discovery.

4:35 A Predictive in vitro Preclinical Package to Assess Safety and Efficacy of ImmTAC™ molecules

Luise_WeigandLuise U. Weigand, Ph.D., Team Leader, Cell Biology, Immunocore Ltd.

ImmTAC molecules are bispecific molecules comprising a pico-molar affinity T cell receptor fused to an anti-CD3 specific scFv that re-direct a potent T cell response towards target cells. Here we present our in vitro approach for preclinical assessment. The full in vitro package is used to evaluate safety and efficacy of ImmTAC molecules. The predictability of this process for our most advanced molecule IMCgp100, currently in a Phase I/II study, is discussed.

5:05 A Microfluidic Model for Lymphocyte-Tumor Interactions

Jeffery_BorensteinJeffrey Borenstein, Ph.D., Laboratory Technical Staff, Biomedical Microsystems, Draper

Here we describe a multiplex microfluidic chip that sustains tumor samples for periods of days to weeks in a microenvironment that provides precision dynamic control over oxygen gradients, temperature, and lymphocyte concentration. We demonstrate this system in the absence and the presence of compounds known to influence interactions between lymphocytes and tumors, toward application of the technology as a tool for the development of new immunotherapies and ultimately personalized cancer treatments.
