In acute lymphoblastic leukemia (ALL), a new approach to targeting mutated Notch1 will be discussed from presentation of an initial small-molecule library screen, through compound validation and mechanism of action, to development and testing of a more leukemia-selective derivitization strategy. In the case of acute myeloid leukemia (AML), novel targets of myeloid differentiation will be presented. Room 113, Pennsylvania Convention Center genetic alterations that occur in bladder cancer, yet the specific functional drivers of these processes are only now beginning to be understood. This functional delineation is critical in providing targets for therapeutic intervention. We used a new functional genomic screen in experimental tumors and human specimens and found AGL, a glycogen debranching enzyme deficient in glycogen storage disease, is a new suppressor of in vivo bladder cancer growth and patient prognostic. Metabolic and transcriptional profiling coupled with gene targeting studies showed that reduced AGL enhances tumor growth by inducing hyaluronic acid synthesis. Surprisingly, low AGL also makes cells vulnerable to molecular blockade of glucose import and autophagy. This work is the first to show an enzyme implicated in congenital liver disease also regulates cancer growth and provides hitherto unappreciated biomarker and therapeutic opportunities. Terrace Ballroom II-III (400 Level), Pennsylvania Convention Center Basic Science Insights to Guide PI3K Pathway Targeting in Cancer The Cancer Epigenome Bart Vanhaesebroeck, UCL Cancer Institute, London, United Kingdom Peter A. Jones, Van Andel Research Institute, Grand Rapids, MI Deregulation of PI3K pathway components is very common in cancer, and therapeutic interference with PI3K signaling is high on the pharma agenda. Current basic science insight into the roles of PI3K and downstream signaling in cancer biology will be reviewed. This includes the roles of the different PI3K isoforms, the existence of feedback loops, and the emerging evidence for an important role of PI3K in regulation of the tumor stroma, such as through the regulation of angiogenesis and immunomodulation. Epigenetic processes are reinforced by interactions between covalent chromatin marks such as DNA methylation, histone modifications, and variants. These marks ultimately specify the locations of nucleosomes particularly with respect to transcriptional start sites and other regulatory regions. Importantly, many of these enzymes which catalyze these processes are now known to be mutated in human cancers. We have developed a new methodology to simultaneously map nucleosomal positioning and DNA methylation on individual DNA molecules and have combined this approach (NOMe-seq) with ChIP-seq to obtain a comprehensive view of the chromatin states at transcription start sites (TSS), and also at enhancers, CTCF sites, and gene bodies. The results elucidate a key role for DNA methylation in the down regulation of TSSs and enhancers, no visible role in the overall structure of CTCF sites, and up regulation of expression when located in gene bodies. Whole epigenome analysis also shows altered chromatin structural alterations in cancer which might help explain the macropscopic changes visible to pathologists in cancer cells. Room 119, Pennsylvania Convention Center Bladder Cancer: Functional Genomics Leading to Targeted Therapy Dan Theodorescu, University of Colorado Cancer Center, Aurora, CO Bladder cancer is the most common malignancy affecting the urinary system with an estimated 72,570 new cases and 15,210 deaths in 2013 in the United States. Significant advances have occurred since 2011 in the delineation of the April 18-22, 2015 • Philadelphia, PA 295 12_15AM_Mon_Layout 1 3/27/15 12:23 PM Page 296 MEET-THE-EXPERT SESSIONS Monday, 7:00 a.m.-8:00 a.m. Room 122, Pennsylvania Convention Center Head and Neck Cancer: Translational Research Strategies Jennifer Rubin Grandis, University of California, San Francisco, CA Head and neck squamous cell carcinoma (HNSCC) is a common malignancy worldwide. HNSCC arising from tobacco exposure is frequently lethal despite intensive multimodality therapy. HNSCC linked to infection with the human papilloma virus (HPV) is rapidly increasing in incidence and is generally associated with a more favorable prognosis compared with HPV[-] HNSCC. The EGFR targeted antibody cetuximab is the only FDA-approved molecular targeting agent for HNSCC. Even though most HNSCCs express relatively high levels of EGFR, relatively few individuals are cured with cetuximab therapy. The ability to prevent and treat HNSCC is primarily limited by an incomplete understanding of the biological underpinnings of the disease. Major gaps in knowledge include a lack of predictive biomarkers to any treatment modality and a paucity of HPV-selective therapies, despite increasing evidence that HPV[+] HNSCC is a distinctly different cancer from HNSCC[-] disease. The wealth of genomic and epigenomic data emerging from large-scale studies demonstrates the heterogeneity of HNSCC and underscores the need for a more rational selection of preclinical models for translational research. This presentation will discuss bidirectional translational research approaches in HNSCC to most efficiently achieve the promise of precision head and neck cancer medicine. Room 118, Pennsylvania Convention Center Melanoma - Basic Science David E. Fisher, Massachusetts General Hospital, Boston, MA This session will review aspects of the molecular pathogenesis of melanoma. Topics include the role of MITF, a master transcriptional regulator of melanocyte development, and also a key survival factor in melanoma. MITF is an amplified or mutated melanoma oncogene, and its functions within melanoma are becoming increasingly appreciated. In addition, aspects of melanoma formation will be reviewed. These will include the roles of UV in skin signaling, the role of intercellular communication in mediating UV pigmentation effects of skin. Studies will also review behavioral consequences of UV irradiation, such as 296 UV addictive behaviors, through analyses of genetic models and signaling paradigms. Collectively these studies will span early steps in melanoma formation, risk factors, modulators of treatment responses, and novel therapeutic approaches. Room 114, Pennsylvania Convention Center Molecular Pathology in Oncology Massimo Loda, Dana-Farber Cancer Institute, Boston, MA Pathology connects basic research to clinical practice to make informed decisions about patient care. Molecular pathologists play an essential role in the analysis of genomic data, combining cutting-edge molecular tools with deep understanding of tissue architecture. Linking molecular and morphologic annotation is essential for the identification of prognostic and predictive biomarkers, monitor drug resistance, and to provide a detailed classification of tumors. This is because molecular alterations need to be analyzed in the context of cell of origin, tissue heterogeneity, and tumor microenvironment. Decreasing amounts of neoplastic tissue (e.g., diagnostic biopsies) and increasing demands for material for molecular analyses requires the adaptation of molecular techniques to formalin-fixed paraffin-embedded tissue as well as approaches such as multiplexing in situ technologies for the simultaneous assessment of several biomarkers and ex vivo propagation of tumors. Molecular data need to be interpreted in a context-dependent manner for accurate personalization of diagnosis and treatment. Room 204, Pennsylvania Convention Center Post-GWAS Studies of Epithelial Ovarian Cancer: Now What? Thomas A. Sellers, Moffitt Cancer Center and Research Institute, Tampa, FL Genome-wide association studies (GWAS) have identified roughly 20 loci for risk of epithelial ovarian cancer. In general, the allele frequencies are common and effect sizes are modest. Some loci are associated with all histologic subtypes of ovarian cancer, whereas others are associated in a subtype-specific manner. GWAS success requires large sample sizes to reach the accepted statistical significance threshold, which becomes problematic for a rare cancer. AACR ANNUAL MEETING 2015 12_15AM_Mon_Layout 1 3/27/15 12:23 PM Page 297 Innovative approaches are required to sift through the large number of potential candidates to identify true risk loci. Prior to the GWAS era, genetic epidemiology relied on highrisk pedigrees or sibling-pairs. Inevitably, the responsible disease-causing alteration was a nonsense mutation in a gene-coding region. A major surprise that has emerged from GWAS studies is that the vast majority of risk regions are not in exons. This requires the development of novel assays and a systematic approach to try to identify candidate target genes, the functional variant, and how they interact to influence disease risk. The translational implications from GWAS are numerous, spanning risk prediction, early detection, more precise diagnostics, novel therapeutic targets, and risk reduction interventions. based analysis of genes with significant hazard ratios, we have identified a biological process (immune function) that predicts response to trastuzumab. We are now using multisite annotated clinical trials samples to validate, both analytically and clinically, a genomic profile that predicts response to adjuvant trastuzumab in patients with earlystage HER2-positive breast cancer, and exploring other promising predictive biomarkers in this setting. Room 103, Pennsylvania Convention Center Therapy of Lymphoma Inspired by Functional and Structural Genomics Louis M. Staudt, National Cancer Institute, Bethesda, MD Room 120, Pennsylvania Convention Center Prognostic and Predictive Biomarkers for Anti-HER2 Therapy Edith A. Perez, Mayo Clinic, Ponte Vedra Beach, FL The EGFR family member HER2 (ERBB2) is overexpressed in 15-20% of breast tumors. Although the prognosis for such patients was traditionally generally poor, the addition of the humanized monoclonal anti-HER2 antibodies, such as trastuzumab, has resulted in long-term (10 yr.) diseasefree survival in about 80% of patients with early-stage HER2+ disease. However, about 20% of such patients are refractory to adjuvant trastuzumab-containing regimens and develop tumor relapse within 10 years. The challenge being addressed is to identify this subset of patients, who can then be enrolled in future clinical trials to test the efficacy of emerging HER2-targeted therapies. In short, although we may know how to cure most HER2+ patients, we need to identify patients most likely to benefit from existing therapies while focusing our efforts upon the patients who are unresponsive to the current standard of care. We have completed a comprehensive set of biomarker analyses over the years, culminating in a whole transcriptome analysis of >1,200 patients with early-stage HER2+ disease that led us to three central concepts: 1) that the clinical behavior of HER2+ tumors was linked to biological functions; 2) that these biological functions could be identified using a systems biology approach that focused on networks of genes with significant associations with clinical outcome (Cox hazard ratios); and 3) that different subsets of these genes might govern the relevant biological processes in individual tumors. Using a networkApril 18-22, 2015 • Philadelphia, PA Diffuse large B cell lymphoma (DLBCL) is a heterogeneous diagnostic category that is comprised of two prominent molecular subtypes, termed activated B cell-like (ABC) and germinal center B cell-like (GCB). Constitutive activation of the B cell receptor (BCR) and MYD88 pathways by genetic and non-genetic mechanisms will be discussed, including the role of self-antigens in BCR activation. To attack chronic active BCR signaling therapeutically, we initiated clinical trials in DLBCL of ibrutinib, an irreversible and highly selective inhibitor of BTK. Ibrutinib monotherapy induced a high rate of complete and partial responses in ABC DLBCL, while GCB DLBCL tumors rarely responded. To extend the efficacy of ibrutinib, we have identified additional therapeutic targets in the oncogenic signaling pathways in ABC DLBCL including: 1) ubiquitin ligases, such as LUBAC, 2) the kinase IRAK4, 3) the PI3 kinase pathway, and 4) BCL2. Several synergistic, mechanismbased drug combinations that exploit these redundant survival pathways will be discussed. 297 12_15AM_Mon_Layout 1 3/27/15 12:23 PM Page 298 MEET-THE-EXPERT SESSIONS Monday, 7:00 a.m.-8:00 a.m. Terrace Ballroom I (400 Level), Pennsylvania Convention Center Terrace Ballroom IV (400 Level), Pennsylvania Convention Center Through the Eyes of a Mouse: The p53 Pathway Understanding Cancer: Microenvironment Interactions at Multiple Scales Guillermina Lozano, The University of Texas MD Anderson Cancer Center, Houston, TX Joe W. Gray, Oregon Health and Science University, Portland, OR Mutations in the p53 tumor suppressor are common in human cancers. In particular, p53 missense mutations represent approximately 80% of alterations in tumors. Missense mutations have additional activities, termed gain of function, that result in highly invasive tumors. We and others have generated mouse models to examine the consequences of p53 mutations in tumor development. I will discuss lessons learned from these studies and a new mouse that models somatic inactivation of p53. Revolutionary advances in nucleic acid and protein profiling and multiscale imaging make it possible to identify (epi)genomic abnormalities in cancer and to learn how these abnormalities compromise protein, cell, and tissue molecular architecture at scales ranging from nanometers to centimeters. This presentation will describe a) the use of correlative light and electron microscopy and workflows to define the multiscale molecular architectures of breast and pancreatic cancers, b) high-throughput biological models and analytical processes to assess the functional importance of specific molecular abnormalities and cell-microenvironment interactions, and c) integrative computational approaches. Emphasis will be on understanding how tumor intrinsic changes and cancer cell-microenvironmental interactions influence cancer progression and response to therapy. Room 115, Pennsylvania Convention Center Tumor Dormancy and Metastatic Recurrence Ann F. Chambers, London Regional Cancer Program, London, ON, Canada Most cancer deaths are due to metastatic disease, which is treatable but generally incurable. Metastases can recur long after successful treatment of a primary tumor, even for cancers diagnosed at an early stage. Late recurrences can occur years or decades after initial diagnosis, and some cancers may be considered “chronic relapsing diseases.” Dormant cancer has been shown experimentally and clinically to be a therapeutic target, in groups of patients at risk. However, we do not know which individual patients will benefit from antidormancy therapy, or even the extent of micrometastatic burden in individuals. We also do not know well how to prevent dormant cells from reinitiating growth or how to kill them. We need to identify individuals who harbor dormant disease and develop appropriate long-term therapeutic strategies. We also need to learn if lifestyle interventions or host features vs. properties of the primary tumor affect regrowth of dormant cells. 298 AACR ANNUAL MEETING 2015 12_15AM_Mon_Layout 1 3/27/15 12:23 PM Page 299 NCI/NIH-SPONSORED SESSION (not eligible for CME credit) Monday, 7:00 a.m.-8:00 a.m. Room 105, Pennsylvania Convention Center The NCI PREVENT Cancer Preclinical Drug Development Program Chemoprevention research in the Division of Cancer Prevention (DCP) was restructured in 2011, creating the PREVENT Cancer Preclinical Drug Development Program. This Program provides for peerreview of proposals from the general research community for development of small molecules or biologicals, including vaccines, for cancer prevention or biomarkers to facilitate clinical evaluation of prevention strategies. The process for applying to the Prevent Program is described at: http://prevention.cancer.gov/programs-resources/programs/prevent. Applications are submitted twice yearly and reviewed by a panel of experts from the extramural community and NIH Scientists outside DCP and scored for scientific merit, feasibility, etc. Top scoring applications undergo secondary review and prioritization by a panel of DCP and other NIH scientists. Applications with potential for near-term clinical translation are given highest priority. Approved projects are implemented as Task Orders via a system of contracts with academic and nonprofit, independent research institutions that provide the full range of preclinical studies, including good laboratory practice toxicology, needed to support Investigational New Drug Applications. Twenty-five Task Orders addressing a range of intervention strategies have been awarded in the first two years of the Program. Small molecules targeting classic aspects of inflammation as well as newer molecular-targeted agents (n=16) are under study. Pharmacodynamic assays are coupled to efficacy studies. Immunoprevention strategies targeting tumor-associated antigens as well as antigens from cancer-associated infectious agents (n=6) are being pursued. Preliminary data from current projects will be presented. The PREVENT Cancer Program has engaged a broad cross-section of investigators, supporting preclinical development of agents addressing a wide variety of cancer prevention strategies.

Brock, Johns Hopkins University School of Medicine, Baltimore, MD; John M. Carethers, University of Michigan, Ann Arbor, MI There are challenges to undergo a successful promotion from junior faculty to senior faculty, and strategies are not completely transparent. After the initial appointment, the new faculty must navigate their institutions’ requirements over the ensuing handful of years, be diligent about meeting expectations needed for promotion, and not wait until the last minute to fulfill those expectations. Depending on their job description, performing and publishing scholarly work, acquiring external grant support, successfully participating in the teaching mission of the institution, and satisfying any clinical expectations are weighted. In addition, developing a national reputation is generally a requirement. Intangibles for success will be discussed by those who have achieved promotion, which include strategies for mentorship and the importance of networking, avoiding time-consuming committees before promotion yet participating in the missions of the institution, protecting your effort, suggestions for documenting activities, early strategies for leadership skills development, and troubleshooting difficult situations. The goal of this session is to provide advice to the junior faculty who wants to understand the path towards a successful promotion and to provide advice to set a foundation for future leadership. 9:30 a.m. Introduction Malcolm V.

When used alongside complementary genetic technologies, chemical probes play a key role in functional genome annotation and in interrogating biological pathways and phenotypes of cancer cells and their healthy counterparts. They also make a critical contribution to innovative target discovery and robust target validation. To be effective, chemical tools need to be designed, assessed, and used with a high level of critical rigor. Although there has been a welcome increase in the availability of highquality chemical tools, there continue to be frequent published examples where researchers use unsuitable compounds, often suffering from clearly undesirable chemical structures and/or insufficient potency, selectivity, permeability, and stability – and frequently also lacking essential biomarker evidence of specific target engagement – resulting in misleading biological conclusions. This symposium will assess the state of the art in the design, iterative optimization, and use of chemical tool compounds in cancer research. We will review key “fitness factors” against which chemical probes should be assessed; describe chemical tool kits and frameworks for their biological application; provide cutting edge examples of high-quality chemical reagents and their innovative use in oncology; and describe chemical biology and allied proteomic approaches to target discovery and validation. Specific topics will include comparative on-target and offtarget effects with both chemical and genetic approaches; selectivity and polypharmacology in kinase research; the rapid emergence of chemical tools for epigenetic regulators and metabolism targets; the power of structurebased design; the increasing role of irreversible chemical tools for use in in vitro and animal models; the application of chemical tools in expanding the druggable cancer genome; and contributions to overcoming the key problem drug resistance. The value of chemical probes and chemical biology in driving therapeutic innovation and productivity will be discussed in the context of the current academia-biotech-pharma ecosystem. *An extended abstract for this presentation is available in the Invited Abstracts section of the Proceedings (the abstract number is listed in brackets above). 342 AACR ANNUAL MEETING 2015 12_15AM_Mon_Layout 1 3/27/15 12:23 PM Page 343 Terrace Ballroom I (400 Level), Pennsylvania Convention Center Terrace Ballroom IV (400 Level), Pennsylvania Convention Center Deregulation of Cancer Hallmarks by microRNAs and other Noncoding RNAs Epigenetic and Transcriptional Control of Senescence Chairperson: Frank John Slack, BIDMC Cancer Center/Harvard Medical School, Boston, MA Chairperson: Emily Bernstein, Icahn School of Medicine at Mount Sinai, New York, NY The genome generates an increasing diversity of noncoding RNAs. MicroRNAs (miRNAs) have led the charge in the emergence of RNA molecules functioning in cancer. Analysis of miRNA expression signatures have shown promise in cancer diagnosis, and miRNAs themselves are potential targets/agents for cancer therapy. Playing catch-up, but of no less importance are the scores of long noncoding RNAs (lncRNAs), many of which are also mis-expressed in cancer and likely have important functions. Given the sheer number of miRNA and lncRNAs genes, thousands in humans, and our lack of understanding of all their roles, and given the need for a basic understanding of cancer mechanisms, this session will provide an important synthesis of the growing role for miRNAs and lncRNAs in multiple aspects of cancer biology. Senescence is considered a stable form of growth arrest that functions as a potent tumor modulating mechanism. While evidence that senescence is a chromatin-mediated process is gaining attention, the molecular mechanisms underlying this process remain unclear. This session will focus on recent advances in the epigenetic and transcriptional regulation of cellular senescence, relevant to aging and cancer. Subject matter will include the role of p53 in senescence and cancer, histone modifications, histone variants and their dedicated chaperones, as well as epigenomic profiling studies. 10:30 a.m. Introduction 10:40 a.m. In vivo analysis of linear and circular ceRNAs in tumorigenesis Pier Paolo Pandolfi, BIDMC Cancer Center/Harvard Medical School, Boston, MA 11:00 a.m. Discussion 11:05 a.m. Mechanisms of microRNA dysregulation in cancer Carlo M.

The likelihood to respond to these immunotherapies differs strongly across tumor types. Furthermore, also within tumor types, tumors vary with respect to sensitivity towards immune attack. These data make a better understanding of both intrinsic resistance and acquired immunotherapy resistance the new frontier in this field, with the goal to improve patient selection and counteract immune escape. This session will deal with a series of aspects of the dialogue between the cellular immune system and cancer cells. Topics addressed will range from genomic analyses that aim to uncover tumor cell sensitivity to T cell attack, immunological analyses of mechanisms of T cell dysfunction, and immunohistochemical analysis of immune infiltrates that correlate with patient outcome. 10:30 a.m. Introduction 10:40 a.m. What T cells see on human cancer Ton Schumacher, Netherlands Cancer Institute, Amsterdam, The Netherlands 11:00 a.m. Discussion 11:05 a.m. The immune landscape within human tumors Jerome Galon, INSERM U872 - Cordeliers Research Center, Paris, France Chairperson: Stephen D. Hursting, University of North Carolina at Chapel Hill, Chapel Hill, NC The prevalence of obesity, an established risk and/or progression factor for many cancers, has more than doubled over the past three decades in the United States, with ~36% of adults currently obese (BMI>30 kg/m2). The mechanisms underlying the obesity and cancer connection are becoming increasingly clear and reveal several potential targets and strategies for preventing obesityrelated cancers. We will focus on obesity-related host factors that influence tumor initiation, progression, and/or response to therapy. These host factors include components of the secretome, including hormones, growth factors, adipokines, and cytokines and other inflammationrelated molecules. These secreted host factors are extrinsic to, and interact with, the intrinsic molecular characteristics of cells (including cancer stem cells), and each will be considered in the context of energy balance and as potential targets for breaking obesity-cancer links. 10:30 a.m. Introduction 10:40 a.m. Obesity and breast cancer: Preclinical perspectives Stephen D.

Ratain, University of Chicago, Chicago, IL Oncology drug development has historically relied on the paradigm of phase 1 studies to define a single maximally tolerate dose, single arm phase 2 studies to estimate activity, and phase 3 studies using the same dose defined during early phase 1 trials. This paradigm is based on the assumption that there is a steep dose-response curve and that toxicity is of relatively little concern, as compared to optimizing the probability of demonstrating efficacy. More recently, there has been recognition that dose optimization may be important for many, if not all, oncology drugs, particularly for those drugs that are substantially different from historical chemotherapy agents. The session will include discussion of pharmacological, statistical, commercial, and regulatory issues pertinent to dose optimization of modern oncology drugs. Room 113, Pennsylvania Convention Center Exploiting DNA Repair Deficiencies in Cancer Chairperson: Alan Ashworth, UCSF Helen Diller Family Comprehensive Cancer Center, San Francisco,CA Inherited mutations in DNA repair genes can lead to susceptibility to cancer. Moreover, DNA repair defects also occur in sporadic cancers. Such defects are starting to be exploited therapeutically, particularly through the use of synthetic lethal approaches; the sensitivity of BRCA mutant tumors to PARP inhibitors in the first example of this strategy to reach the clinic.

McKee, U.S. Food and Drug Administration, Silver Spring, MD The Food and Drug Administration Safety and Innovation Act (FDASIA) of 2012 gave the U.S. Food and Drug Administration (FDA) statutory authority to designate medical products as a “Breakthrough Therapy” if the therapy treats a serious or life-threatening disease or condition and preliminary clinical evidence indicates that the drug may demonstrate substantial improvement over existing therapies. Since that time, the FDA has received over 270 Breakthrough Therapy Designation (BTD) applications and granted over 75, of which more than 20 therapies have received accelerated approval, a majority being oncology products. This session will highlight the approval process for several recently approved breakthrough therapies and the impact that accelerated drug access is having on patient treatment in these disease areas. The following drugs will be discussed: • Nivolumab – PD-1 antibody approved to treat metastatic melanoma; • Pembrolizumab – PD-1 antibody approved to treat metastatic melanoma; • Ibrutinib – BTK inhibitor approved to treat chronic lymphocytic leukemia (CLL); • Idelalisib – PI3K inhibitor approved to treat chronic lymphocytic leukemia (CLL); • Palbociclib – CDk4/CDK6 inhibitor approved to treat metastatic ER+/Her2- breast cancer; and • Blinatumomab - CD19-directed CD3 T-cell engager (BiTE) approved to treat acute lymphoblastic leukemia (ALL).

Korsmeyer Memorial Symposium: Cell Death and Cancer Therapy: Why Has Conventional Chemotherapy Been So Successful? Antiangiogenesis Revisited Chairperson: Anthony G. Letai, Dana-Farber Cancer Institute, Boston, MA In this current era of precisely targeted therapies and -omics technologies, it is often forgotten that no medical therapy has cured, and continues to cure, more people of cancer than conventional chemotherapy. Notwithstanding its superior performance across many cancer types, the mechanism of the therapeutic index of conventional agents, largely targeting ubiquitous elements like DNA and microtubules, is poorly understood. The textbook explanation of conventional chemotherapy’s working by killing supposedly rapidly dividing cancer cells lacks clinical evidence and flies in the face of many obvious clinical counterexamples. In this session, the speakers will describe how conventional cytotoxic chemotherapy preferentially kills cancer cells. Moreover, they will describe how clinical response to chemotherapy might be better predicted. 1:00 p.m. Introduction 1:10 p.m. Conventional chemotherapy cures people by exploiting apoptotic priming [SY20-01]* Anthony G. Letai, Dana-Farber Cancer Institute, Boston, MA Chairperson: Donald M. McDonald, UCSF Helen Diller Family Comprehensive Cancer Center, San Francisco, CA Mixed results with angiogenesis inhibitors in cancer therapy have led to reinvestigation of underlying mechanisms and use of combinations with other therapeutic strategies. This symposium will explore new directions that promise greater efficacy. Some oncolytic viruses have more potent, long-lasting actions on primary tumors and metastases when combined with angiogenesis inhibitors. Vascular endothelial growth factor (VEGF) pathway inhibitors are being combined with inhibitors of other VEGF-VEGFR family members or the angiopoietinTie2 receptor pathway. The orphan receptor Tie1 is also a potential target in some tumors. Additional strategies are examining immune cell actions on angiogenesis, invasion, and immune-stimulation by antiangiogenic therapy. Immune modulators can sensitize resistant tumors to antiangiogenic therapy and generate more durable responses. The therapeutic potential of targeting metabolic pathways is another novel strategy. Agents that impact glycolysis or lipid and amino acid metabolism can reduce vessel sprouting and angiogenesis. The speakers will examine the latest findings with these approaches. 1:00 p.m. Introduction 1:10 p.m. Synergy of oncolytic viruses and angiogenesis inhibitors Donald M.

The complexity and heterogeneity of cancer genomes has been laid out in considerable detail for a large number of cancer types over the past few years, as well as marked examples of success in exploiting mutated genes as therapeutic targets. As these efforts and insights gain traction, the framework for their investigation, interpretation, and regulation become of central importance. In this session, we will cover aspects ranging from the potential impact of genomic heterogeneity, the challenges of whole-exome datasets, moving towards large-scale clinical sequencing implementation, and regulatory challenges in the expanding era of interpreting cancer genomes in clinical cancer care. 1:00 p.m. Introduction 1:10 p.m. Somatic genetic heterogeneity in the era of genomic medicine Andy Futreal, The University of Texas MD Anderson Cancer Center, Houston, TX Grand Ballroom (300 Level), Pennsylvania Convention Center Microbiome and Tumor Immunity Chairperson: Giorgio Trinchieri, National Cancer InstituteFrederick, Frederick, MD Commensal microorganisms colonize barrier surfaces of all multicellular organisms. For more than 500 million years commensal microorganisms and their hosts have coevolved and adapted to each other. As a result, the commensal microbiota affects many immune and nonimmune functions of their hosts, and de facto the two together comprise one metaorganism. Microbial imbalance may play a critical role in the development of multiple diseases. The commensal microbiota affects the development, progression, and immune evasion of cancer but it also has important effects on the response to cancer immune- and chemo-therapy. Tumor-associated myeloid cells play a dual role inducing antitumor immune responses but mostly promoting immune evasion, tumor progression, and metastases formation. Myeloid cells respond to signals derived from commensal microbes that modulate their function and reactivity in inflammation and their ability to act as antigen presenting cells controlling adaptive immunity, thus affecting the tumor environment and the response to cancer therapy. 1:00 p.m. Introduction 1:30 p.m. Discussion 1:10 p.m. 1:35 p.m. Clinical whole exome interpretation for precision cancer medicine [SY16-02]* Eliezer M.

It is still very much debated whether these transcripts are simply noise or represent functional entities. Although noncoding genes vastly outnumber protein-coding genes in our genome, they have not been studied or sequenced systematically, if at all, in the various “cancer anatomy efforts,” nor have they been functionalized to determine their possible role in tumorigenesis. In this session we will discuss the transformative impact of the noncoding RNA dimension in cancer research and therapy as studied in vivo in animal models. We will discuss how current modeling efforts in the mouse are demonstrating the critical role of the “dark matter” and its central relevance in our ability to comprehensively deconstruct the pathogenesis of human cancer and to develop novel diagnostic and therapeutic strategies. Room 103, Pennsylvania Convention Center Targeting Pathway Rewiring to Improve Cancer Therapy Chairperson: Michael B. Yaffe, MIT Koch Institute for Integrated Cancer Research, Cambridge, MA Both the emergence of malignant cells and their subsequent resistance to killing by molecularly targeted and cytotoxic therapies arises from rewiring of signaling pathways that control cell growth, proliferation, invasion, and programmed cell death. This session will review how the continual ability of cancer cells to rewire signaling pathways leads to the emergence of therapeutic resistance, both through tumor cell autonomous changes and through tumor cell manipulation of the local microenvironment. Presenters will then demonstrate how a detailed molecular understanding of this process can lead to novel therapeutic strategies that can kill these resistant clones and/or prevent their emergence. Finally, this session will show how the inherent plasticity of signaling pathways in cancer can also be taken advantage of therapeutically in order to make tumor cells sensitive to drugs that they were not previously sensitive to, through a process called “therapeutic dynamic rewiring.” 1:00 p.m. Introduction 1:10 p.m. Therapeutic network rewiring of the DNA damage response can be used to enhance tumor killing by cytotoxic chemotherapy [SY19-01]* Michael B.

While targeting specificity is important for the reduction of adverse effects, biodistribution is dominantly determined by the ability of therapeutic agents to navigate a daunting sequence of biological barriers, including endothelia and epithelia, the reticulo-endothelial system, the cancer stroma, target cell membranes, and subcellular barriers such as the endosomal membrane and multidrug resistance efflux pumps. Thus, the development of novel therapeutics requires not only progress in their molecular targeting specificity, but also in their delivery across barriers, to reach desired distributions. Often, however, the addition of specificity decreases the transport properties of the therapeutic moiety, as for instance is the general case in the transition from small molecule chemotherapeutics to large biomolecular targeted therapeutics. The need to strike a balance between these two aspects poses problems of extraordinary complexity. In this session, four different strategies will be presented and discussed, to generate novel classes of cancer therapeutic agents with favorable properties of transport, biodistribution, and targeting specificity, drawing from the combined worlds of nanomedicine and molecularly targeted therapeutics. 1:20 p.m. Discussion 1:00 p.m. 1:25 p.m. Tracking immune response through T cell receptor sequencing Lawrence H.

Brinton, National Institutes of Health, Bethesda, MD Although obesity is a risk factor for a number of cancers, the magnitude of association is strongest for the development of endometrial cancer, the most common gynecologic cancer in U.S. women. The obesity epidemic in the United States and around the world raises significant concerns regarding future increases in the incidence of endometrial cancer. Obesity may have special implications for certain subgroups of women and/or for the development of unique subsets of tumors. The effects of weight loss on endometrial cancer associated biomarkers and risk patterns are of obvious interest as they may offer prevention opportunities among those at high risk. Given the strength of association of obesity with endometrial cancer, novel options for chemoprevention in obese women warrant specific attention. 1:00 p.m. Obesity and its implications for changes in endometrial cancer incidence and mortality Louise A.

These neuroendocrine lung tumors are often initially responsive to first-line therapy, but relapse is common and little can be done currently against these recurrent tumors. No targeted therapies are approved for SCLC. This session will present recent advances that provide a better understanding of the molecular and cellular underpinnings of SCLC progression. In particular, genetic and genomic approaches (including preclinical mouse models and cancer genomics studies) are uncovering fundamental biological processes as well as key vulnerabilities in SCLC, and a particular emphasis will be placed on novel candidate targeted therapies for SCLC patients. Chairperson: Iannis Aifantis, HHMI/NYU School of Medicine, New York, NY Leukemia and lymphoma and more specifically lymphoid malignancies have been at the forefront of genomic and epigenetic discovery in cancer. During the last decade we have appreciated the role of the epigenome (DNA methylation, histone methylation, nucleosome remodeling) in the induction and progression of lymphoid neoplasms. Indeed, a large number of mutations targeting epigenetic factors were identified in acute lymphocytic leukemia (ALL), chronic lymphocytic leukemia (CLL), and lymphoma. Moreover, both DNA methylation and histone modification alterations have been used to group and stratify patients with distinct clinical features and treatment outcomes. Finally, more recent work suggested key roles for enhancer elements in lymphoid malignancies and introduced compounds that can target enhance integrity and function as putative therapeutics. Drs. Pasqualucci, Ferrando, Aifantis, and Martin-Subero will present new data connecting the epigenome to lymphoid leukemia/lymphoma initiation, progression, and therapeutic targeting. 1:00 p.m. Epigenetic landscape of small cell lung cancer Charles M.

DeBerardinis, UT Southwestern Medical Center, Dallas, TX Brain cancers are characterized by a number of metabolic alterations that participate in cellular transformation and/or support tumor cell growth. Because these alterations distinguish tumor tissue from normal brain, some of them present outstanding opportunities to diagnose and treat cancer in novel ways. Important metabolic changes in brain tumors include oncogene-induced reprogramming of nutrient uptake and utilization and, in tumors with mutations in isocitrate dehydrogenase-1 or -2 (IDH1, IDH2), synthesis of the oncometabolite 2-hydroxyglutarate. This session will explore recent progress in understanding and exploiting these metabolic changes. Topics to be discussed will include new discoveries of metabolic pathways that fuel glioma cell growth in culture and in vivo; updates on the effects of inhibiting mutant IDH isoforms on glioma cell growth and differentiation; and recent advances in the use of metabolic imaging techniques, particularly magnetic resonance spectroscopy, to diagnose brain tumors and predict their clinical course. 1:00 p.m. Mutant IDH1 as a therapeutic target in glioma Paul S.

Cantley, PhD, FAACR Sandra and Edward Meyer Cancer Center at Weill Cornell Medical College, New York, NY The AACR Princess Takamatsu Memorial Lectureship was established and first presented in 2007 in honor of the late Princess Takamatsu of Japan. During her extraordinary life, Her Imperial Highness Princess Takamatsu expended tremendous efforts toward the public and humanitarian cause of the eradication of cancer. She is an honored and respected figure in Japan, the United States, and the cancer research community worldwide. The Lectureship recognizes an individual scientist whose novel and significant work has had or may have a farreaching impact on the detection, diagnosis, treatment, or prevention of cancer, and who embodies the dedication of the Princess to multinational collaborations. Dr. Lewis C. Cantley is honored for his discovery of the phosphoinositide 3-kinase (PI3K) enzyme and the subsequent work delineating the PI3K signaling pathway. Dr. Cantley’s research has shown that this pathway is commonly activated in cancer and has paved the way for the development of therapeutics aimed at inhibiting PI3K signaling. This work is already having a genuine impact on cancer patients and perfectly captures the spirit of this award. His laboratory demonstrated the importance of activation of P13K and the downstream signaling pathway and they developed novel of peptide libraries that revealed the structural specificity of phosphorylation-dependent protein networks that regulate this pathway and other signaling pathways. Mutations that activate P13K are among the most frequent genetic alterations in human cancers. The first PI3K inhibitor for cancer therapy was approved in 2014 and more than 20 PI3K inhibitors are currently in clinical trials for a wide variety of cancers. April 18-22, 2015 • Philadelphia, PA Dr. Cantley’s scientific accomplishments have been recognized with numerous additional honors throughout his career, including the inaugural Breakthrough Prize in Life Sciences, the H.C. Jacobaeus Prize, the Pasarow Award for Cancer Research, the Rolf Luft Award from the Karolinska Institute, the Pezcoller Foundation-AACR International Award for Cancer Research, and the Caledonian Prize Lectureship in Biomedical Science from the Royal Society of Edinburgh. Additionally, he is an elected member of the National Academy of Sciences, the Institutes of Medicine and the American Academy of Arts and Sciences. Dr. Cantley graduated from Wesleyan College and received his PhD in biophysics from Cornell University. In 1992, he assumed the position of chief of signal transduction at Beth Israel Deaconess Medical Center and Harvard Medical School. He currently occupies the position of Meyer Director of the Sandra and Edward Meyer Cancer Center at Weill Cornell Medical College/New York Presbyterian Hospital. 417 12_15AM_Mon_Layout 1 3/27/15 12:23 PM Page 418 NCI/NIH-SPONSORED SESSION (not eligible for CME credit) Monday, 3:30 p.m.-5:00 p.m. Room 105, Pennsylvania Convention Center Biospecimens to Support Cancer Research Co-Chairpersons: Irina Lubensky, Danielle Carrick, and Helen M. Moore, National Cancer Institute, Bethesda, MD This session will present information regarding the acquisition and utilization of cancer and normal biospecimens for cancer research. NCI Biospecimen Resources Available to the Research Community Moderators: Irina Lubensky, Cancer Diagnosis Program, Division of Cancer Treatment and Diagnosis, National Cancer Institute, Bethesda, MD Aniruddha Ganguly, Cancer Diagnosis Program, Division of Cancer Treatment and Diagnosis, National Cancer Institute, Bethesda, MD The first part of the session will provide information about two quality human biospecimen resources supported by NCI and available to the researchers for discovery and validation of biomarkers of diagnosis, prognosis and response to therapy. The Cooperative Human Tissue Network (CHTN) and NCI National Clinical Trials Network (NCTN) Biospecimen Banks will be described in detail, including the types of samples (paraffin embedded, fresh frozen, blood, fluid, etc.) and the extent of clinical data available. Access to biospecimens, application process and evaluation, criteria for specimen distribution, fee structure and examples of successful research projects using each resource will also be discussed. NCI Specimen Resource Locator tool for finding biospecimen resources will be highlighted. Speakers: William Grizzle, University of Alabama, Birmingham, AL Mark Watson, Washington University, St. Louis, MO Utilizing FFPE Tissues in Genomic Research Section Moderator: Danielle Carrick, Epidemiology and Genomics Research Program, Division of Cancer Control and Population Sciences, National Cancer Institute, Bethesda, MD The second part of the session will focus on how formalinfixed paraffin-embedded (FFPE) tissue may be acquired and used as a reliable alternative to fresh frozen tissue for genomic cancer research. While most population-based molecular studies use whole blood or fresh frozen tissue 418 specimens, FFPE tissue is more widely available and more easily obtained. The potential utility of FFPE tissue as a source of DNA and RNA for next generation sequencing (NGS) would greatly enhance population-based cancer studies. Moreover, translation of these technologies may require understanding challenges and limitations of using FFPE samples processed in non-uniform manners in clinical settings. Speakers will discuss challenges and considerations for obtaining and using FFPE tissue and potential approaches to overcome those challenges. Speakers: Rulla Tamimi, Harvard School of Public Health, Boston, MA P. Mickey Williams, Frederick National Laboratory for Cancer Research, Frederick, MD Normal Biospecimens and Reference Genomic Data: The GTEx Project Section Moderator: Helen M. Moore, Biorepositories and Biospecimen Research Branch (BBRB), Division of Cancer Treatment and Diagnosis, National Cancer Institute, Bethesda, MD The third part of the session will provide information about acquiring normal tissue for research studies. The session will provide an overview of the NIH Genotype Tissue Expression (GTEx) project and highlight the operational, Informatics, biospecimen, and data resources that have been developed. The GTEx Project is a Common Fund Project of the NIH that was designed to build the resources and infrastructure for researchers to address the question of how variability in genotype influences gene expression and phenotypic endpoints in normal, non-diseased individuals. This project has addressed and overcome many of the challenges of normal tissue collection and has developed a unique set of resources including standard operating procedures (SOPs) for the acquisition, storage, use and distribution of biospecimens; an IT infrastructure that allows a standardized approach for acquiring, annotating and tracking biospecimens; a biobank with biospecimens from over 25 organ sites from 900 individual donors; and a large dataset of genomic data available for researchers through dbGaP.

Kluetz, U.S. Food and Drug Administration, Silver Spring, MD Patient-Reported Outcomes (PROs) have been defined as “any report of the status of a patient’s health condition that comes directly from the patient, without interpretation of the patient’s response by a clinician or anyone else.” When integrated into clinical trials, accurate and carefully obtained PRO data can provide additional patient-centered information to inform regulators, clinicians, and patients on the risks and benefits of a therapeutic product. The U.S. Food and Drug Administration, (FDA) has previously released guidance on “Patient-Reported Outcome Measures: Use in Medical Product Development to Support Labeling Claims” to provide recommendations for the design of PRO instruments and clinical trials. While the Guidance is meant to apply across therapeutic areas, it has become clear that oncology trials present unique challenges for PRO including frequent open label and single-arm trial designs, missing data, lack of statistical rigor, and therapies that often cause significant toxicity. There has been a redoubling of efforts to address these challenges by FDA and others. This session will explore efforts being made by all stakeholders to improve PRO data from cancer clinical trials with the goal of increasing the amount of PRO data in FDA labels. Representatives from the FDA, industry, academia, and the patient advocacy community will discuss the opportunities and challenges in assessing PRO in cancer clinical trials. The challenge of missing data will be further explored including methods to mitigate this common problem. A panel discussion will be moderated by Paul G. Kluetz, U.S. Food and Drug Administration, and audience Q and A will follow the presentations. Speakers: Paul G.

Knudsen, PhD Interim Director, Sidney Kimmel Cancer Center Interim Chair and Hilary Koprowski Endowed Professor, Department of Cancer Biology Professor of Cancer Biology, Urology Radiation Oncology and Medical Oncology, Sidney Kimmel Medical College, Thomas Jefferson University Join us at Booth #1827 at AACR Annual Meeting 2015 to meet the editors of the AACR Publications. The Editors-in-Chief will explain the mission and scope of their journal, recent submission trends, and other topics of interest for researchers looking to publish their work in the highly esteemed AACR journals. Learn what Editors look for in manuscripts and participate in a unique Q&A session. Molecular Cancer Research publishes articles describing novel basic cancer research discoveries of broad interest to the field. Studies must be of demonstrated significance, and the journal prioritizes analyses performed at the molecular and cellular level that reveal novel mechanistic insight into pathways and processes linked to cancer risk, development, and/or progression. Areas of emphasis include all cancer-associated pathways (including cell-cycle regulation; cell death; chromatin regulation; DNA damage and repair; gene and RNA regulation; genomics; oncogenes and tumor suppressors; and signal transduction), in addition to studies describing new molecular mechanisms and interactions that support cancer phenotypes. For full consideration, primary research submissions must provide significant novel insight into existing pathway functions or address new hypotheses associated with cancer-relevant biologic questions. 420 AACR ANNUAL MEETING 2015 12_15AM_Mon_Layout 1 3/27/15 12:23 PM Page 421 AACR-ROSENTHAL AWARD LECTURE Monday, 4:30 p.m.-5:30 p.m. Terrace Ballroom II-III (400 Level), Pennsylvania Convention Center Thirty-Ninth Annual AACR Richard and Hinda Rosenthal Memorial Award Systematic Identification of Cancer Targets William C. Hahn, MD, PhD Dana-Farber Cancer Institute, Boston, MA The American Association for Cancer Research and the Rosenthal Family Foundation originally established this award in 1977 to recognize research that has made notable contributions to improving clinically based cancer care. In an effort to honor and provide incentive to early investigators, the foundation has restricted award recipients to the age of 50 years at the time the award is presented. Dr. William C. Hahn is honored for his seminal contributions to the understanding of the mechanisms underlying cancer initiation, maintenance, and progression. Dr. Hahn’s work has defined new conceptual paradigms and provided a foundation for novel therapeutic approaches that are now being tested in the clinic. Dr. Hahn has pioneered the use of systematic approaches to understand cancer phenotypes and has been a singular innovator in creating the means to create experimental cancer models of defined genetic composition. Adapting genetice methods used in model organisms, Dr. Hahn has performed a series of studies to identify genes whose expression/function is essential in particular genetic contexts. Identifying these codependencies or synthetic lethal partners provides the means to decipher the wiring of cancer cells and also o identitify novel approaches to target tumor suppressor genes and oncogenes. Dr. Hahn’s laboratory recently demonstrated that specific memembers of the proteasome and spliceosome are required in cells that exhibit hemizygous loss of these genes. This work, together with recent work from the DePinho and Ashworth laboratories, provides a rationale for how targeting sememingly essential processes leads to enhanced responses in cancer compared to normal cells. Dr. Hahn’s laboratory has also discovered that the transcriptional regular YAP1 is required for the survival of colon cancers that harbor constitutively active b-catenin/WNT signaling and that the serine-theronine kinase TBK1 is synthetic lethal partner that acts to promote tumor cell survival in cancers depenedent on KRAS. Onoing work in Dr. Hahn’s laboratory has identified an oncogienic DRAS-driven cytokine loop regulated by TBK1 that is amendable to pharmacologic inhibition of TBK1. Clinical trials involving this small molecule inhibitor of TBK1 (CYT387, momelotinib) have started for patients with KRAS mutant pancreatic and lung cancers. Dr. Hahn has been a member of the Harvard Medical School faculty throughout his career, which is where he also received his bachelor’s, medical, and doctoral degrees. Additionally, he was a resident at Massachusetts General Hospital, a clinical fellow at the Dana-Farber Cancer Institute/Partners Cancer Care Program, and a postdoctoral fellow at the Whitehead Institute. Dr. Hahn’s dedication and innovative approaches to cancer research are continuing to transform the field.

Moderator: William Pao, Roche Pharma Early Research and Development, Basel, Switzerland Experts will discuss perspectives on drug discovery from academia and industry, with a focus on how both can work effectively together. Panel: Mace L. Rothenberg, Pfizer, Inc., New York, NY Charles L. Sawyers, Memorial Sloan Kettering Cancer Center, New York, NY Room 113, Pennsylvania Convention Center The Cancer Epigenome: Is Epigenetic Deregulation the Chicken or the Egg? Moderator: Stephen B. Baylin, Johns Hopkins University School of Medicine, Baltimore, MD It is apparent over the past 15 or so years that epigenetic alterations, involving DNA methylation, chromatin, or both, are a constant feature of virtually all cancer types. There is a building theme that at least some of these abnormalities are key drivers for cancer initiation and progression. However, when these occur, and their importance, with respect to occurrence of genetic changes for cancer initiation especially are still widely debated. These questions are heightened now that we know that mutations in genes encoding regulators of the epigenome are frequent in most cancer types. The chicken or egg question inherent to these issues will be addressed by the speakers in this session. Panel: Christopher J. Kemp, Fred Hutchinson Cancer Research Center, Seattle, WA Jean-Pierre J. Issa, Fels Institute for Cancer Research and Molecular Biology, Philadelphia, PA Moderator: Julian Downward, Cancer Research UK, London, United Kingdom Mutation of RAS genes leads to dominant gain of function oncogenic changes as a result of loss of GTP hydrolysis activity. However, it has also been observed that many tumors with RAS mutations have also lost expression of wild type alleles of the gene, suggesting the possibility that wild type RAS could have a tumor suppressive role. On the other hand, evidence has recently been found that wild type RAS signaling can continue to fulfil an essential role in cancer cells that is distinct to that of mutant RAS. We will discuss the latest thinking regarding the role of wild type RAS proteins in RAS mutant cancers and whether or not targeting wild type RAS proteins is likely to be beneficial or harmful in this context. Panel: Kevin M. Shannon, University of California, San Francisco, CA Minh D. To, University of Toronto, Toronto, ON, Canada Room 115, Pennsylvania Convention Center Dietary Supplements and Cancer Risk and Prognosis Moderator: Cornelia M. Ulrich, Huntsman Cancer Institute, University of Utah, Salt Lake City, UT A large proportion of men and women in the United States and worldwide use dietary supplements. Motivations are to improve general health, reduce cancer risk and, for cancer patients, to aid recovery and improve chances of survival. What is the evidence in support of these expectations and what are the potential harms associated with dietary supplement use? This forum will discuss findings to date on the benefits and risks of dietary supplements in cancer risk and prognosis – highlights will include antioxidants, folate and vitamin D, among others. Gaps in our knowledge, as well as future research strategies will be discussed. Panel: Marian L. Neuhouser, Fred Hutchinson Cancer Research Center, Seattle, WA Tim E.

Moderator: Pasi A. Jänne, Dana-Farber Cancer Institute, Boston, MA MET signaling plays an important role in biological properties in cancers including cell migration, metastases, and resistance to targeted therapies. Several strategies to inhibit MET have been developed and have been or are undergoing clinical evaluation. Many of these have been conducted in patients with lung cancer and to date the vast majority of the studies have been negative in the clinic. In this session we will review the biology of MET and evaluate the various therapeutic approaches. We will dissect whether the negative clinical results are due to incomplete understanding of MET biology, or to ineffective strategies to inhibit MET or due to wrong clinical trial designs. Panel: Paolo M. Comoglio, Institute for Cancer Research and Treatment - IRCC, Candiolo (Torino), Italy D. Ross Camidge, University of Colorado Denver, Aurora, CO April 18-22, 2015 • Philadelphia, PA Terrace Ballroom IV (400 Level), Pennsylvania Convention Center Opportunities and Challenges in the Use of Animal Models for Cancer Target Validation and Drug Development (not eligible for CME credit) Moderator: Robert T. Abraham, Pfizer Pharmaceuticals, San Diego, CA Cancer researchers now have access to a diverse array of preclinical cancer models, including conventional human cell line xenografts, patient-derived xenografts (PDX), and genetically engineered mouse models. These in vivo disease models have yielded fundamental insights into tumor biology, and have proven indispensable for the validation of cancer drug targets, the testing of drug candidates and combinations, and biomarker identification. However, each animal model bears certain biological and technical limitations that, depending on the specific experimental setting, have important implications for both the practical application of the model, and the relevance of the preclinical results to the clinical diseasel. For example, panels of PDX models of a specific cancer subtype permit an assessment of inter- and intratumoral heterogeneity on disease biology and drug responsiveness, but the immunocompromised state of the host limits their usefulness for studies of tumor-host interactions and immunotherapeutic drug candidates. This Forum will provide an opportunity for an open discussion of the current opportunities and challenges stemming from the use of animal models of human cancer, and of technical advances on the horizon that might further enhance the predictive potentials of these models in academic and pharmaceutical research. 5:00 p.m. Introduction Robert T.

Arteaga, Vanderbilt-Ingram Cancer Center, Nashville, TN; Peter Yu, Palo Alto Medical Foundation, Sunnyvale, CA Excess body weight has been associated with increased breast cancer risk. This relationship has been attributed to higher estrogen levels in women with high BMI. However, obesity is also associated with high insulin levels and inflammation, there is a well-recognized crosstalk between estrogen receptor and insulin/IGFs signaling, and hyperinsulinemic states – such as diabetes – are also associated with a higher risk of breast cancer. All these suggest that insulin levels might be a dominant mechanism. Along these lines, use of hypoinsulinemic agents such as metformin, has been correlated with better outcome in cancer patients treated with chemotherapy. Speakers in this session will review the pathogenic mechanisms linking obesity, hyperinsulinemia, and inflammation to breast cancer risk and progression, as well as epidemiological studies in this area and therapeutic interventions which may interfere with this signaling axis, thus providing opportunities for cancer prevention and treatment. 5:00 p.m. Metabolic syndrome, inflammation, and cancer: The hidden risks of obesity Clifford A.

Herbst, Yale Cancer Center, New Haven, CT Combustible tobacco use remains the leading preventable cause of premature mortality, killing more than five million people worldwide every year. We know that tobacco use is causally associated with 18 different cancers, including lung, head and neck, stomach, pancreas, and cervical cancers, and alone tobacco accounts for 30 percent of all cancer deaths. In the past few decades, the rate of combustible tobacco product use has declined, but there has been a recent, rapid increase in the use of electronic nicotine delivery systems (ENDS), which include electronic cigarettes, or e-cigarettes, devices that are capable of delivering nicotine in an aerosolized form. These devices have been promoted as potential cessation products and safer alternatives to combustible cigarettes. However, at the present time definitive data are lacking on the health consequences of ENDS use and their value as tobacco cessation aids. Additionally, unlike combustible cigarettes and other tobacco products, ENDS are not currently regulated by the U.S. Food and Drug Administration (FDA). Additional research is needed to inform the regulation of ENDS and there is also a need for policies to aid in the minimization of the potential negative public health consequences of these products, particularly youth initiation of ENDS use. In this session the speakers will discuss additional research needs to inform the regulation of ENDS, as well as the policy recommendations outlined in the recently released joint American Association for Cancer Research (AACR) and American Society of Clinical Oncology (ASCO) statement that provides recommendations seeking to guide policymakers in the regulation of ENDS, especially youth-oriented ENDS use and marketing, without undermining the potential of these products to reduce harm as a smoking cessation tool.

CLOWES LECTURE Monday, 5:30 p.m.-6:30 p.m. Grand Ballroom (300 Level), Pennsylvania Convention Center Fifty-Fifth Annual AACR G. H. A. Clowes Memorial Award Finding Therapeutic Targets for Aggressive Prostate Cancer Owen N. Witte, MD, FAACR University of California, Los Angeles, CA This award was established in 1961 by AACR and Eli Lilly and Company to honor Dr. G.H.A. Clowes, a founding member of AACR and past research director at Eli Lilly and Company. The award recognizes an individual that has had outstanding recent accomplishments in the field of basic cancer research. Dr. Owen N. Witte is recognized for his many contributions to the understanding of human leukemias, immune disorders, and epithelial cancer stem cells. His innovative work has revolutionized modern cancer treatment by defining tyrosine kinases as crucial drug targets in human disease. These studies have led to the development of several approved targeted therapies, transforming the lives of patients with Philadelphia chromosome-positive leukemias and B-cell malignancies. Dr. Witte has played a major role in the discovery of the ABL fusion oncoproteins in leukemia, defining their properties as tyrosine kinases and characterization of their properties as oncogenes in mouse models of leukemia. At UCLA, Dr. Witte was the first to show that Philadelphia chromosome, positive CML cells had an abberant ABL protein with associated tyrosine kinase activity. Later Dr. Witte showed that this BCR-ABL oncogene was sufficient to cause leukemias in mouse models. Based on this, he predicted that CML patients should benefit from inhibition of the BCR-ABL oncoprotein. As they say, the rest is history. Dr. Witte has provided the basis of a now very successful therapy for patients with CML. His work over the past 25 years serves as the most compelling case of target validation in human cancer and illustrates the critical importance of research in fundamental disease mechanisms to guide the development of specific therapies. In studies on growth control of immature B cells, Dr. Witte and colleagues also identified a new cytoplasmic tyrosine kinase (BTK) and showed that its loss could lead to a block in B cell development and proliferation. These studies again predicted that BTK is a valuable target in certain lymphomas and autoimmune diseases. Again, history repeats itself, his fundamental insights into the biology of BTK has resulted in the approval of Ibrutinib in 2013 for Chronic Lymphocytic leukemia and Mantle Cell Lymphoma. Dr. Witte is a member of the National Academy of Sciences and the Institute of Medicine of the National Academies. Among his many recognitions are the Milken Foundation Award in Basic Cancer Research, the Rosenthal Award of the AACR. He was recently also elected as a fellow of the American Association for Cancer Research Academy. To these recognitions, he can now add the 55th Annual AACR G.H.A. Clowes Memorial Award. 428 AACR ANNUAL MEETING 2015 12_15AM_Mon_Layout 1 3/27/15 12:23 PM Page 429 SPECIAL SESSION (not eligible for CME credit) Monday, 6:00 p.m.-8:00 p.m. Grand Ballroom Salon H (Level 5), Philadelphia Marriott Downtown Joint Cancer Immunology (CIMM)/Tumor Microenvironment (TME) Working Groups Evening Scientific Session The emerging success of tumor immunotherapy heralds a new chapter in the treatment of advanced cancers.
