Models for Cancer Track Banner


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 trials. 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 (usually in vivo) 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. The need for stimulating the response of the immune system adds to the complexity of preclinical models and the applications. Cambridge Healthtech Institute’s Preclinical Models for Cancer Immunotherapy and Combinations conference aims to bring together cancer researchers and clinicians in order to initiate knowledge and opinion exchange around preclinical tumor models, including immunocompetent models, and the strategies for preclinical design and assessment of cancer immunotherapy and combination therapy.

AMG 330 is a Bispecific T-cell engager (BiTE®) antibody construct binding to CD33 and CD3, which efficiently redirects cytotoxic T cells against CD33-expressing cells. In vitro and in vivo studies support clinical development of AMG 330 for the treatment of acute myeloid leukemia.

9:00 A Predictive in vitro Preclinical Package to Assess Safety and Efficacy of ImmTACs

Laure_HumbertLaure Humbert, Ph.D., Senior Scientist, Preclinical Biology, Immunocore Ltd.

ImmTACs 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. This entirely in vitro package is used to evaluate safety and efficacy of ImmTACs. The predictability of this process for our most advanced molecule IMCgp100 currently in a Phase I/II study is discussed.

9:30 Immunotherapy for Head and Neck Cancer: Using T-Cells to Drive Away the Tumour

Marc Davies, Ph.D., CAR Mechanics Laboratory, Research Oncology, Division of Cancer Studies, King’s College London

To treat refractory squamous cell carcinoma of the head and neck (SCCHN), we have engineered tumour-specific T-cells through expression of a Chimeric Antigen Receptor (CAR) that targets the extended ErbB family. Efficacy and safety of this approach were confirmed using several in vitro and in vivo models. A Phase I clinical evaluation is now ongoing in patients with locally advanced/recurrent SCCHN in whom CAR T-cells are delivered using the intra-tumoural route.

IMMUNOCOMPETENT MODELS AND LARGE SCALE
IN VIVO SCREENING

10:45 Immunocompetent Mouse Models as a Tool for Cancer Immunotherapy Pipeline Advancement

Christian_GerdesChristian Gerdes, Ph.D., Head of 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.

11:15 Mouse Clinical Trials: Large Scale in vivo Screening Predicts Drug Response in Cancer Patients

Michael_Rugaard_JensenMichael Rugaard Jensen, Ph.D., Director, Head of ONC Discovery Pharmacology Basel, Novartis Institutes for BioMedical Research

We established a panel of more than 1,000 patient-derived tumor xenograft models (PDX), with comprehensive genomic landscape analyses. Using this PDX collection, we performed population-based in vivo compound screens using a 1x1x1 experimental design to assess the response and resistance of 70 treatments across six indications. We demonstrate both the reproducibility and clinical translatability of this approach and additionally demonstrate examples of PDX superiority over cell-based xenografts in predicting clinical response.

11:45 Preclinical Assessment of Immune Checkpoint Inhibitors and Their Combinations: IDO1 Inhibitor Case Study

Gregory_DriessensGregory Driessens, Ph.D., Head of in vivo Pharmacology, iTeos Therapeutics SA

Tumors use tryptophan-catabolizing enzymes like IDO1 to induce an immunosuppressive microenvironment. PF-06840003 is a new highly selective orally bioavailable IDO1 inhibitor able to reverse IDO1-induced T-cell anergy in vitro. PF-06840003 reduced intratumoral kynurenine and inhibited tumor growth in multiple preclinical syngeneic models, in combination with immune-checkpoint inhibitors. PF-06840003 has favorable predicted human pharmacokinetic properties, including a predicted t1/2 of 16-19 hours, highlighting its strong potential as a clinical candidate in Immuno-Oncology.

MASTERING TRANSLATIONAL IMMUNO-ONCOLOGY

14:15 Chairperson’s Remarks

Christian Gerdes, Ph.D., Head of Pharmacology, Roche Pharma Research & Early Development, Roche



14:20 KEYNOTE PRESENTATION:
Stress, Death, Immunity and Cancer Therapy

Lorenzo_GalluzziLorenzo Galluzzi, Ph.D., Université Paris Descartes

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.

14:50 Applying Preclinical Immuno-Oncology Mouse Models to Guide Combination Strategies in the Clinic

Elaine_PinheiroElaine M. Pinheiro, Ph.D., Principle Scientist, In Vivo Pharmacology, Immuno-Oncology, MSD, Merck

Immunotherapeutic strategies, such as checkpoint blockade, have changed the way cancers are being treated, providing significant benefit to patients. Despite success, a large fraction of patients do not respond to single agent therapy. Combination approaches may be the key to improving response rates in these patients. Preclinical immuno-oncology mouse models provide tremendous value to shaping clinical strategies given that countless potential combinations exist with other immunotherapies, radiation, and/or standard of care. In turn, data from clinical trials can be used to formulate hypothesis about biological mechanisms that can be appropriately and productively tested in preclinical models to drive the development of novel immunotherapeutic approaches and combination strategies. This talk will provide an overview of the limitations, predictive nature, and role of these models in guiding treatment options at the bedside.

HUMANIZED MODELS AND BEYOND

8:25 Chairperson’s Remarks

Christine Sedlik, Ph.D., Institut Curie

8:30 Preclinical Development of Humanized Mouse Models to Evaluate Cancer Immunotherapies

Christine_SedlikChristine Sedlik, Ph.D., Institut Curie

To improve our understanding and to build better, more translatable in vivo mouse tumor models, we are focusing on the development of humanized mouse models consisting of the transplant of patient-derived tumor xenografts (available at Institut Curie) into immunodeficient mice reconstituted with human immune cells (isolated from the matching patient from the draining lymph nodes or with allogenic PBMCs).

9:00 Use of Juvenile Animal Studies as a Preclinical Model to Support Oncology Medicine Development in Children

Dinah_DuarteDinah Duarte, Pharm.D., MSc, Head, Scientific Evaluation Unit, Directorate of Medicinal Products, INFARMED, Portugal

Childhood cancer has remained a challenge because of long-term effects in children. The need to extend children’s access into new cancer therapies requires early prediction of safety aspects and juvenile animal studies (JAS) are being conducted to screen for age-related toxicities and differences occurring during postnatal development. The retrospective review of the oncology EU medicines and Paediatric Investigation Plans is illustrative of the potential significance of JAS in oncology medicines.

9:30Enhancing Immunotherapy Radiotherapy Combinations Using the Small Animal Radiation Research Platform

Andrew Lessey, Business Development Specialist, Xstrahl Limited

The synergistic effect of combining Immunotherapeutic agents with radiotherapy has been employed to great success in some instances within the clinic. However, the benefits of trialling these combinations in a preclinical setting has been routinely been examined in a very crude manner or ignored until the clinic thus far. We have developed the SARRP to allow researchers to accurately examine these combinations in small animal models.

NOVEL APPROACHES: ORGANOIDS AND GENE EDITING

10:45 Patient-Derived Tumour Organoids for Drug Screening and Development

Sylvia_BojSylvia Boj, Ph.D., Group Leader, Foundation Hubrecht Organoid Technology (HUB Foundation)

Organoid 3D growth systems were devised for studying the role of adult stem cell function and cell differentiation. The organoid models essentially contribute an in vitro mini organ setting that allows the expansion of normal and tumour patient-derived cells. The generation of ‘Living Organoid Biobanks’ from cancer patients will provide a valuable platform for drug development. The possible value of organoids for predicting therapy responses for patients is currently being assessed.

11:15 Modelling and Targeting Pancreatic Cancer and Its Microenvironment by Genome Engineering and Gene Editing in Mice

Dieter_SaurDieter Saur, M.D., Consultant and Senior Group Leader, Technische Universität München (TUM), School of Medicine

We generated novel PDAC models that permit spatial and temporal control of gene expression and modelling of PDAC subtypes. These tools provides unparalleled access to the native biology of cancer cells and their hosting stroma, and rigorous genetic validation of candidate therapeutic targets in autochtonous tumours and the immune system.

11:45 Generation of ex vivo Tumor Models from PDX Tumors as a Platform for Clinically Relevant Anticancer Drug Discovery

Geoffrey_BartholomeuszGeoffrey 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 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.
