CHI’s Combination Immunotherapy Design Models, February 20-22, 2017, Moscone North Convention Center, San Francisco, CA – part of the 24th International Molecular Medicine Tri-Conference
Reporter: Aviva Lev-Ari, PhD, RN
Despite tremendous progress in our understanding of cancer biology, the majority of novel anticancer therapies fail in clinical trials, which indicates deficiencies in conventional translational approaches. In most cases preclinical data have overpredicted clinical efficacy in oncology. With the rise of immuno-oncology the challenge of in vivo pharmacology was enhanced by the differences in mouse and human immune systems that further damages the predictiveness of preclinical data. The phenomenon of cancer heterogeneity and subsequent drug resistance add another dimension to the preclinical cancer research warranting active work on combination cancer regimens. Better models and approaches are clearly in high and urgent demand and has been worked on by industry and academia scientists. Cambridge Healthtech Institute’s Fifth Annual Translational Models in Oncology and Immuno-Oncology conference is designed to highlight cutting edge advances in in vivo, in vitro and in silico modeling and to facilitate a discussion about effective translational approaches in cancer research.

12:00 pm KEYNOTE PRESENTATION: Rational Development of Combination Therapies in Immuno-Oncology
Michael Kalos, M.D., CSO, Cancer Immunobiology, Eli Lilly
Treatment of patients with combinations of agents, such as CTLA4 and PD1, has provided additional benefit to patients, along with increased toxicity, highlighting the value for developing combination therapies. In this session, we will discuss preclinical and translational strategies and approaches to support the rational development of more effective combination strategies that lead to increased clinical benefit for patients.
12:30 Biomarker Development for the Era of Combination Cancer Immunotherapy
Terri McClanahan, Ph.D., Executive Director, Molecular Discovery, Biologics, Merck Research Laboratories
Keytruda® (pembrolizumab), a PD-1-specific monoclonal antibody, is approved in the U.S. for advanced melanoma, NSCLC and SCCHN, and is being studied in >30 cancers. Efforts are now underway to extend the benefit of cancer immunotherapy to more patients through the use of anti PD-1-based combination regimens. However, significant challenges remain to identify the best combinations that provide true immune synergy, and to target the right combinations to the right patients who will experience unambiguous clinical benefit. Biomarker and translational research-driven strategies can guide the future state of the field, ultimately allowing for the development of precision medicine approaches to combination cancer immunotherapy.

2:40 Immunocompetent Mouse Models as a Tool for Cancer Immunotherapy Pipeline Advancement
Christian Gerdes, Ph.D., Head, Pharmacology, Roche Pharma Research & Early Development, Roche
As immunotherapy gains more and more traction, the need for more predictive preclinical models grows as well. It is widely recognized that immunocompetent mice are used to assess the anti-tumor efficacy of cancer immunotherapies. This presentation will discuss the uses of mouse models and how they can advance drug pipelines.
3:10 Designing and Executing Cancer Immunotherapy Clinical Trials
Pamela N. Munster, M.D., Professor, Medicine, Program Leader, Development Therapeutics, Director, Early Phase Clinical Trials Program, Helen Diller Cancer Center, University of California, San Francisco
A breakdown in immune tumor surveillance plays a crucial role in the development of metastatic cancer. Targeting the programmed death receptor (PD-1) and its ligand (PD-L1) have been major breakthroughs in certain cancers such melanoma, lung and other cancers. However, many cancers, including breast cancers, appear less responsive. We are exploring the roles of tumor lymphocyte infiltration, T cell differential, epigenetic modifiers and the co-operative involvement of other immune pathways to induce responses in immune silent tumors. Translating preclinical findings into early phase clinical studies, we will describe recent advances in how to determine safety, feasibility and efficacy of integrating immunotherapy into targeted therapy and chemotherapy.
3:40 Talimogene Laherparepvec in Combination with Checkpoint Inhibitors: From Bench to Bedside
Pedro J. Beltran, Ph.D., Research Director, Oncology Research, Amgen, Inc.
Checkpoint inhibitors and viral immunotherapy with talimogene laherparepvec have shown significant therapeutic benefit in melanoma patients when used as monotherapies. As these two forms of approved immunotherapy act mostly on different parts of the immunity cycle, studying their combination pre-clinically and clinically informs their future development. We have used 3 syngeneic murine models to study the pharmacodynamic and efficacy changes driven by the combination of talimogene laherparepvec and blockade of CTLA-4 or PD-1/PD-L1. Clinical trials testing these combinations in the clinic are currently ongoing.

10:15 Mouse Models to Test Human Cancer Immuno-Therapeutics
Gavin Thurston, Vice President, Oncology and Angiogenesis Research, Regeneron Pharmaceuticals
Preclinical in vivo tumor models are essential to test anti-tumor activity and side-effect profiles of novel immunotherapeutics. However, antibody-based therapies often do not cross-react with the corresponding murine targets, making such tests difficult. We have utilized Regeneron’s capabilities in murine genetic engineering to develop several approaches of combining functional immune cells with preclinical tumor models. We have used these approaches for preclinical testing of both checkpoint inhibiting antibodies and T cell-engaging bispecific antibodies.
10:45 Characterization of Molecular and Cellular Properties of Murine Syngeneic Models to Aid Model Selection and Biomarker Discovery for Immune-Oncology Programs
Wenyan Zhong, Ph.D., Senior Principal Scientist, Oncology R&D Group, Pfizer
Preclinical in vivo models for most immuno-oncology (IO) programs require the use of immunocompetent mice bearing syngeneic tumors. To facilitate model selection for use in preclinical efficacy studies, we characterized a panel of mouse tumor cell lines and syngeneic tumor tissues. In this talk, we will discuss molecular and cellular properties of these models.
11:15 Case Study: Blockade of Phosphatidylserine-Mediated Tumor Immune Suppression to Enhance Immune Checkpoint Therapies
Michael Gray, Ph.D., Senior Research Scientist, Peregrine Pharmaceuticals
Phosphatidylserine (PS) exposure in tumors induces non-inflammatory signals which contribute to an immunosuppressive environment. Antibody blockade of PS activates immune responses by promoting M1 macrophages, maturation of dendritic cells and inducing adaptive T-cell responses. PS targeting antibodies enhance the anti-tumor activity of checkpoint antibodies in preclinical tumor models.
11:45 Methods and Models for Preclinical Immuno-Oncology
Dylan Daniel, Ph.D., Director, Scientific Development, MI Bioresearch
MI Bioresearch has characterized an array of syngeneic immuno-oncology models to support in vivo pharmacology drug discovery. Our characterization includes comprehensive lymphoid and myeloid flow cytometry immune profiling, and model responses to checkpoint inhibitors and focal beam radiotherapy combinations.
12:00 pm 
Genetically Engineered Miniswine Models of Cancer
John Swart, Ph.D., President, Exemplar Genetics
Current preclinical models of cancer fail to accurately recapitulate human disease and do not effectively translated to the clinic. Recently, Exemplar Genetics has developed a genetically engineered miniature swine model that contains a conditional KRAS mutation on the background of TP53-targeted pigs, the ExeGen® TP53+/R167H& KRAS+/G12D miniswine model. This model should allow for the inducement of human-like tumors in a tissue specific manner. Initial characterization of induced tumors demonstrates the transformative nature of this model.

Combination approaches are the keys to improving clinical response. From preclinical immune-oncology mouse models to patients enrolled on clinical trials, novel high throughput technologies enable us to understand the mechanisms underlying the complex interactions between the immune system and cancer, identify predictive biomarkers for the patients who will most likely benefit from current immunotherapies, avoid immune-related adverse events and guide the future combination cancer immunotherapy.
11:30 High-Content Molecular Profiling in Preclinical Immuno-Oncology Research
Ruslan Novosiadly, Senior Research Advisor, Cancer Immunobiology, Biomarkers, Eli Lilly
Recent clinical data have revealed the remarkable potential for T cell modulating agents to induce potent and durable responses in a subset of cancer patients. In this presentation, we discuss molecular approaches, platforms and strategies that enable a broader interrogation of the activity of agents that modulate the activity of tumor-specific T cells as well as examples of data sets generated in preclinical studies that have provided important insights into the biological activity of T cell therapies and support further rational development of this exciting treatment modality.
12:00 pm Utility of Quantifying Circulating Lymphocyte Populations as Pharmacodynamic Biomarkers in Trials of Immune Oncology Therapeutics
Nathan Standifer, Ph.D., Scientist II, Clinical Pharmacology and DMPK, MedImmune
Immune oncology (IO) therapeutics are directed at inducing immune responses against tumor cells. Intrinsic to this mechanism of action is the activation of circulating immune cells, which can be most effectively monitored using flow cytometry-based assays. In this presentation, aspects of assay development, validation, implementation and analysis of clinical flow cytometry datasets will be discussed. Results from clinical trials of IO as single agents or in combination with other IO will be shown and strategies for interpretation and post-hoc analyses will be detailed.

2:00 Understanding and Predicting Cellular Response through Chemical and Functional Genomic Profiling of Well-Characterized Cancer Cell Lines
Scott Martin, Senior Scientific Manager, Group Lead, Functional Genomics, Discovery Oncology, Genetech
Determining relationships between genomic features and drug sensitivity is central to the concept of personalized medicine and indication selection. Many studies have highlighted the value of integrating omics data with drug activity across cell lines to identify predictors of response. Here we extend upon these studies with numerous chemical and genetic perturbations to explore such relationships. Data reveals both known and novel correlations, and was also used to explore best experimental and computational practices.
2:30 Beyond Genomics: Identifying Treatment Options for Refractory Cancer Patients Using Real Time Functional Assays and FDA Approved Drug Combinations
Matthew De Silva, CEO, Founder, Notable Labs
Refractory cancer patients often have resistant disease that does not respond to single agent therapy. Combination strategies are promising, but patient heterogeneity makes clinical trial design difficult. Next generation functional phenotypic assays using a patient’s cancer cells can identify potentially synergistic treatments in a matter of days, but the combinatorial space is often larger than the available cells. In silico models that employ ‘omic data from a patient can prioritize which combinations to test ex vivo. If the agent(s) of choice are approved, physicians can then prescribe them
3:00 Generation of ex vivo Tumor Models from PDX Tumors as a Platform for Clinically Relevant Anticancer Drug Discovery
Geoffrey A. Bartholomeusz, Ph.D., Associate Professor and Director, siRNA Core Facility, Department of Experimental Therapeutics, Division of Cancer Medicine, The University of Texas MD Anderson Cancer Center
Monolayer cell cultures platforms inadequately represent the complex tumor microenvironment and drugs identified by these systems have failed when translated into the clinics. Clinically relevant PDX systems are both costly and time consuming. We have developed a clinically relevant ex vivo tumor tissue system derived from a PDX tumor, and preliminary data confirms its potential to serve as a platform for clinically relevant drug discovery in a time and cost effective manner.

3:45 Cancer Modeling with in vivo CRISPR/Cas9 Genome Editing
Monte Winslow, Ph.D., Assistant Professor, Genetics, Stanford University
Conventional genetically engineered mouse models of human cancer have been instrumental in our understanding of all aspects of cancer development. However, these models are much too labor-intensive, expensive, and slow to perform the extensive molecular analyses needed to adequately comprehend this disease. I will discuss our ongoing work to employ CRISPR/Cas9-mediated genome editing to generate cancer models and illuminate gene function during cancer progression within the natural in vivo setting.
4:15 Tailored Pre-Clinical Models with CRISPR-Based Genome Editing
Lukas Edward Dow, Assistant Professor, Medicine, Weill Cornell Medicine
CRISPR/Cas9 genome editing has changed the way we design and execute in vivo experiments. We are using CRISPR-based genome editing in stem cells and in adult mice to generate tailored pre-clinical models. This allows both a deeper understanding of the genetic underpinnings of cancer progression and provides a platform to interrogate new therapeutic strategies in specific genetic contexts, which is key for realizing the potential of personalized medicine.
4:45 The Human Cancer Model Initiative
Louis M. Staudt, M.D., Ph.D., Director, Center for Cancer Genomics, Co-Chief, Lymphoid Malignancies Branch, National Cancer Institute, National Institutes of Health
The Human Cancer Model Initiative (HCMI) aims to generate 1000 new cancer cell lines directly from patient biopsy material using a variety of technologies, including organoids and conditionally reprogrammed cells. Each cell line will be genomically characterized and clinical diagnostic and therapeutic data will be gathered from the participating patients. The new cell lines and their associated data will be made available to the research community to promote a deeper understanding of cancer and its response or resistance to therapy.
