Macara, Vanderbilt University Medical College, Nashville, TN Cancers are caused by mutations but are also diseases of cell behavior. Oncogenic mutations can often be tolerated within a normal epithelial tissue environment, and we propose that release from homeostatic constraints permits the display of the tumorigenic phenotype. Most human cancers arise from epithelial cells or their progenitors, and a key feature of these cells is apical/basal polarity. Polarity signaling through the Par3 protein suppresses tumor growth and dissemination in several mouse models, and Par3 protein expression is suppressed in human breast cancers. In normal mammary tissue, the loss of Par3 triggers two contradictory responses - rapid cell death through apoptosis and hyper-proliferation. Oncogenic activation blocks apoptosis and reveals the proliferative response, driving increased tumor growth. This session and the ensuing discussion will address the impact of collective epithelial cell behavior on the tumor phenotype, and possible directions towards new therapies. describe a comprehensive program to identify and characterize the functional consequences and therapeutic liabilities engendered by specific aberrations found in patient tumors for the effective implementation of personalized cancer therapy. Room 201, Pennsylvania Convention Center Drugging the Undruggable Using Fragment-Based Methods Stephen W. Fesik, Vanderbilt University School of Medicine, Nashville, TN Only about 10% of the 30,000 proteins in the human genome are thought to be druggable with small molecules. Thus, many proteins that could serve as excellent targets for therapeutic intervention may be difficult or impossible to drug. One approach for discovering small molecules against these challenging targets is fragment-based methods. In this presentation, the theoretical and practical aspects of fragment-based methods will be described. In addition, examples will be presented that illustrate the power of this approach for targeting challenging cancer targets that exert their effects through protein-protein interactions. Terrace Ballroom I (400 Level), Pennsylvania Convention Center Delivering on the Promise of Personalized Cancer Therapy Terrace Ballroom IV (400 Level), Pennsylvania Convention Center Gordon B. Mills, The University of Texas MD Anderson Cancer Center, Houston, TX Genomic Approaches to Cancer Drug Discovery The realization of the promise of personalized molecular medicine requires efficient development and implementation of novel targeted therapeutics linked to molecular markers able to identify patients most likely to benefit. The plethora of aberrations present in each tumor, the need to distinguish drivers from passengers, and the combinatorial effects of aberrations on critical cellular functions represent key challenges to the successful implementation of personalized medicine. To optimally benefit patients, we must manage patients based on the functional consequences of the specific aberrations present in their tumor. Indeed, even in a known cancer gene, aberrations can be passengers, hypermorphs (increased activity), hypomorphs (decreased activity), or neomorphs that mediate novel functions that require different personalized management approaches. I will Todd R. Golub, Broad Institute of MIT and Harvard, Cambridge, MA April 18-22, 2015 • Philadelphia, PA Genomic approaches are now becoming possible not just to characterize cancer genomes, but to facilitate the process of drug discovery. In particular, the testing of drug sensitivity across a large panel of genetically characterized cancer cell lines can be powerful. We will discuss a new approach to such cell line profiling, termed, PRISM, whereby pools of molecularly barcoded cell lines are profiled as mixtures of cell lines. In addition, high throughput gene expression profiling as part of the Connectivity Map/LINCS project can be used as a means to gain insights into small-molecule mechanism-of-action. The use of the Connectivity Map to support discovery will be discussed. 439 13_15AM_Tue_Layout 1 3/27/15 12:24 PM Page 440 MEET-THE-EXPERT SESSIONS Tuesday, 7:00 a.m.-8:00 a.m. Room 121, Pennsylvania Convention Center Heterogeneity of Hepatocellular Carcinoma: From Bench to Bedside Hongyang Wang, Eastern Hepatobiliary Institute, Shanghai, China The heterogeneity of the tumor is a big obstacle for personalized therapy. Hepatocellular carcinoma (HCC) is an extraordinarily heterogeneous disease because, in addition to the common intrinsic cancer heterogeneity resulting from genome instability, a number of epigenetic alterations occur, induced by host microenvironment and several etiologies (virus infection, sexual susceptibility, metabolic disorder, gut microbiome, alcohol intake, and nonalcoholic steatohepatitis). Although many efforts have been devoted to identifying genes responsible for tumorigenesis in the past few decades, the questions of when to treat, what to target, in which patient, and how to monitor the cancer recurrence are still unsolved. Hence, a better understanding of the more sophisticated crosstalk between diversified tumor subpopulations and their dynamic environments in driving HCC progression is critical for personalized prevention and treatment for HCC patients. Terrace Ballroom II-III (400 Level), Pennsylvania Convention Center MYC and Metabolism Meet on the Road to Cancer Chi Van Dang, Abramson Cancer Center of the University of Pennsylvania, Philadelphia, PA MYC is one of the most frequently amplified genes in human cancers, accounting for over 30% of ovarian cancer and well over 15% of uterine, breast, and esophageal cancers. MYC is pathognomically activated by chromosomal translocation in Burkitt lymphoma. Its ectopic deregulated expression in transgenic mice resulted in tumorigenesis in a broad range of tissues, attesting to its tumorigenic role in vivo. MYC encodes the Myc transcription factor that dimerizes with Max to bind and regulate target genes. Comprehensive biological, genomic, chromatin immunoprecipition, and metabolomic studies revealed that Myc is an oncogenic transcription factor that amplifies gene expression in a nonlinear fashion to coordinate nutrient acquisition with macromolecular synthesis, redox homeostasis, and ribosome biogenesis for cell growth and division. The role of Myc in regulating glutamine metabolism and fatty acid synthesis will be discussed in the context of potential therapeutic opportunities directed at cancer metabolism. Room 115, Pennsylvania Convention Center mTOR Complex 1, Metabolism, and Therapeutic Opportunities John Blenis, Weill Cornell Medical College, New York, NY The mTOR Complex 1 (mTORC1) signaling pathway has evolved to sense and respond to cellular energy status, nutrient availability, and surrounding oxygen concentrations. In addition, mTORC1 can be further activated by mitogen- and hormone-activated AGC kinases including Akt and RSK, and suppressed by S6K1 via a variety of negative feedback loops. The integration of these multiple inputs control the strength and duration of downstream signaling, which is important in differentially regulating mTORC1-dependent processes such as protein synthesis and cellular metabolism. I will discuss how mTORC1 and S6K1 regulate aspects of nutrient metabolism, mRNA metabolism, and protein production; biological processes critical to the control of cell growth while at the same time creating vulnerabilities that may provide important therapeutic opportunities in cancers with activated mTORC1 signaling. 440 Room 114, Pennsylvania Convention Center Myeloid-Derived Suppressor Cells in MDS Pathogenesis Alan F. List, Moffitt Cancer Center and Research Institute, Tampa, FL Despite the diversity of somatic genetic events in myelodysplastic syndromes (MDS), these disorders share common biological features of accelerated attrition of hematopoietic progenitors in an inflammatory bone marrow (BM) microenvironment. Mounting evidence implicates sustained activation of innate immune signaling in both hematopoietic senescence and the pathobiology of MDS. In particular, BM expansion and activation of myeloidderived suppressor cells (MDSC) have emerged as key cellular effectors with a pathogenetic role in hematopoietic impairment. MDS-MDSC are clonally distinct from the neoplastic clone, indicating that these cells derive from non-neoplastic myeloid progenitors that precede emergence of the genetically distinct MDS clone. MDSC generate hematopoietic suppressive cytokines and AACR ANNUAL MEETING 2015 13_15AM_Tue_Layout 1 3/27/15 12:24 PM Page 441 function as potent cytocidal effectors targeting autologous hematopoietic progenitors. BM expansion of MDSC is driven by interaction of the pro-inflammatory dangerassociated molecular pattern (DAMP) heterodimer S100A8/S100A9 with its native receptors, CD33 and TLR-4. Evidence from an S100A9 transgenic mice model shows that forced BM expansion of MDSC by S100A9 is sufficient for MDS development manifested as multilineage cytopenias and cytological dysplasia, thereby phenocopying human MDS. In vitro neutralization of S100A9 in primary human MDS BM specimens markedly improves colony-forming capacity and decreases cell death. Therapeutic interventions that promote MDSC maturation or disrupt S100A9 signaling may improve hematopoiesis in MDS. Room 113, Pennsylvania Convention Center Noninvasive Diagnostic Approaches: Circulating Tumor Cells Mehmet Toner, Massachusetts General Hospital, Charlestown, MA Viable tumor-derived circulating tumor cells (CTCs) have been identified in peripheral blood from cancer patients and are probably the origin of intractable metastatic disease. However, the ability to isolate CTCs has proven to be difficult due to the exceedingly low frequency of CTCs in circulation. We introduced several microfluidic methods to improve the sensitivity of rare event CTC isolation, a strategy that is particularly attractive because it can lead to efficient purification of viable CTCs from unprocessed whole blood. Our most recent technology is a tumor marker free (or antigen-independent) approach for sorting of CTCs based on the inertial focusing strategy, which allows positioning of cells in a near-single file line, such that they can be precisely deflected using minimal magnetic force. We applied this microfluidic platform to blood samples obtained from lung, prostate, breast, colon, melanoma, and pancreatic cancer patients. This presentation will share our integrated strategy to simultaneously advance the engineering and microfluidics of CTC-Chip development, the biology of these rare cells, the potential clinical applications of circulating tumor cells. April 18-22, 2015 • Philadelphia, PA Room 103, Pennsylvania Convention Center Precision Medicine: Intentional and Incidental Germline Testing Judy E. Garber, Dana-Farber Cancer Institute, Boston, MA Germline genetics has entered a new era with the use of next-generation sequencing. Germline testing for cancer susceptibility is more often performed using “panel” tests of multiple genes. Targeted gene testing may be an interim strategy before whole exome/whole genome, or may be best for this purpose once optimized. This strategy ensures that fewer individuals will remain uncharacterized, and that estimates of penetrance and the range of tumors associated with germline mutations in specific genes will be revised, as the populations tested become less and less selected. The number of variants of uncertain significance is larger for the expanded number of genes examined, but this is a temporary problem. The identification of potential germline predisposition mutations in the course of tumor genomic analysis is an increasingly common occurrence in precision medicine. The germline findings increase the power and utility of genomics in cancer medicine. Strategies for communication of test results that include germline data benefit from advanced planning. Room 108, Pennsylvania Convention Center Radiation and Immunotherapy: From Preclinical Models to Cancer Patients Silvia C. Formenti, New York University, New York, NY Ionizing radiation can induce immunogenic cell death of tumors, an effect likely to contribute to the success associated with radiotherapy (RT) of cancer. Recent discovery suggests that radiotherapy can be applied as a powerful adjuvant to immunotherapy and contribute to convert the irradiated tumor into an in situ vaccine, resulting in specific immunity against metastases. Preclinical models of syngeneic tumors have reliably predicted clinical success, in several distinct tumor settings and immunotherapy/radiation combinations. For instance, the success of anti-CTLA4 antibody and RT in a syngeneic murine model of mammary carcinoma was mirrored by systemic responses in metastatic melanoma and lung cancer patients irradiated to one metastatic site, during anti-CTLA-4 monoclonal antibody ipilimumab. While promising, this evidence remains preliminary and this session will discuss research opportunities to define the optimal immunotherapy/RT combinations. 441 13_15AM_Tue_Layout 1 3/27/15 12:24 PM Page 442 MEET-THE-EXPERT SESSIONS Tuesday, 7:00 a.m.-8:00 a.m. Room 204, Pennsylvania Convention Center Room 120, Pennsylvania Convention Center Stem Cells XBP1 Promotes Triple-Negative Breast Cancer By Controlling the HIF1 Transcriptional Program Catriona H. M. Jamieson, UCSD Moores Cancer Center, La Jolla, CA Clinical translation of stem cell research-related discoveries is predicated on developing novel tools that can detect and genetically correct stem cell defects, enhance self-renewal of normal stem cells, and rejuvenate aged stem cells as well as eradicate malignant stem cells. The hematopoietic system has served as a paradigm for defining genetic and epigenetic regulators of self-renewal in protective stem cell niches in both normal and malignant hematopoiesis. However, the plethora of changes that occur in other tissue-specific stem cells in the context of heritable as well as somatic mutations and epigenetic alterations during aging and malignant transformation have yet to be clearly understood or corrected. The ultimate goals of the regenerative medicine field include defining seminal gene correction methods to reengineer genetically defective stem cells to adopt normal cell fate decisions, identifying genetic and epigenetic regulators capable of promoting normal-tissue-specific stem cell regeneration that will enable development of optimal expansion technologies, and elucidating the factors that promote stem-cell rejuvenation in an aged host. In addition, early detection and elimination of cells that have co-opted stem cell pathways and thus have been reprogrammed to behave like cancer stem cells has been a major focus of the field. In this session, recent research insights into stem cell gene correction, self-renewal, and rejuvenation will be discussed with an emphasis on improving tissue homeostasis and stem cell dynamics in response to injury and aging as well as in the setting of inflammation and cancer. 442 Laurie Glimcher, Weill Cornell Medical College of Cornell University, New York, NY Triple-negative breast cancer (TNBC), a form of breast cancer in which tumor cells do not express the genes for estrogen receptor, progesterone receptor, and Her2/neu, is a highly aggressive malignancy with limited treatment options. We have recently reported that XBP1, a key component of endoplasmic reticulum (ER) stress and the Unfolded Protein Response (UPR), is activated in TNBC and plays a pivotal role in the tumorigenicity and progression of this human breast cancer subtype. Depletion of XBP1 inhibited tumor growth and tumor relapse by reducing the chemotherapy-resistant CD44high/CD24low population, while enforced XBP1 expression in CD44low/CD24high cells conferred tumorinitiating properties on them. Hypoxia-inducing factor (HIF)1α is known to be hyperactivated in TNBCs and also required for the self-renewal of breast TICs3-6 . Genomewide mapping of the XBP1 transcriptional regulatory network revealed that XBP1 drives TNBC tumorigenicity by assembling a transcriptional complex with HIF1α that regulates the expression of HIF1α targets via the recruitment of RNA polymerase II. Analysis of independent cohorts of patients with TNBC revealed a specific XBP1 gene expression signature that was highly correlated with HIF1α and hypoxia-driven signatures and that strongly associated with poor prognosis. Our findings reveal a key function for the XBP1 branch of the UPR in TNBC and imply that targeting this pathway may offer alternative treatment strategies for this aggressive subtype of breast cancer.

Dirks, University of Toronto Hospital for Sick Children, Toronto, ON, Canada Cancers, both solid and liquid, consist of phenotypically heterogeneous cell types that make up the full cellular complement of disease. Deep sequencing of bulk cancers also frequently reveals a genetic intratumoral heterogeneity that reflects clonal evolution in space and in time and under the influence of treatment. How the distinct phenotypic and genotypic cells contribute to individual cancer growth and progression is incompletely understood. In this symposium, we will discuss issues of cancer heterogeneity and effects on growth and treatment resistance, with emphasis on cancer cell functional properties and influences of the microenvironment, interclonal genomic heterogeneity, and lineage relationships between cancer cells with stem cell and differentiated properties. Understanding these complex cellular relationships within cancers will have critical implications for devising more effective treatments. 10:30 a.m. Introduction 10:40 a.m. Origins, evolution, and selection in childhood leukemia Tariq Enver, Cancer Research UK, London, United Kingdom 11:00 a.m. Discussion 11:05 a.m. Cytokine-controlled stem cell plasticity in intestinal tumorigenesis Florian Greten, Georg-Speyer-Haus, Frankfurt, Germany 11:25 a.m. Discussion 11:30 a.m. Intratumoral heterogeneity in human serous ovarian carcinoma [SY23-03]* John P.

Yet, this technological revolution has highlighted the need for innovative computational approaches to turn the massive data generated into tangible benefits in cancer biomarker and drug discovery, and ultimately patient benefit. In this session we will explore how the application of computational approaches has driven in the discovery of drivers of cancer tumorigenesis and drug resistance, the identification of new generations of cancer drug targets, and tackling resistance through effective cancer drug combinations. We will also highlight innovative tools developed along the way to manage, analyze, and integrate multidisciplinary cancer data and make it available for public benefit. 10:30 a.m. Introduction 10:40 a.m. Selecting future cancer drug targets Bissan Al-Lazikani, The Institute of Cancer Research, London, United Kingdom 10:55 a.m. Discussion 11:00 a.m. Calling both simple and complex mutations in cancer genome David Haussler, Howard Hughes Medical Institute, Santa Cruz, CA 11:15 a.m. Discussion 11:20 a.m. Perturbation biology of cancer cells for the discovery of targeted combination therapy Chris Sander, Memorial Sloan Kettering Cancer Center, New York, NY 11:35 a.m. Discussion 11:40 a.m. Exploring the cancer genome atlas for cancer subtypes and targetable alterations Nikolaus Schultz, Memorial Sloan Kettering Cancer Center, New York, NY 11:55 a.m. Discussion Grand Ballroom (300 Level), Pennsylvania Convention Center Dharma Master Jiantai Symposium in Targeted Therapy: How to Combine Targeted Therapy with Immunotherapy Chairperson: Antoni Ribas, UCLA Medical Center, Los Angeles, CA Small molecule inhibitors of driver oncogenes give high response rates, but responses are usually limited by frequent development of acquired resistance. Cancer immunotherapy tends to have lower response rates, but most responses are long lasting. There has been a lot of interest to rationally combine both treatment strategies. Key to these combinations are the potential effects of the targeted therapies on immune effector cells, which can change their function and may result in toxicities. In addition, small molecule inhibitors can be used to improve the tumor microenvironment by blocking oncogenic signaling leading to immune suppressive factor production by cancer cells, or directly inhibiting or depleting immunesuppressive tumor microenvironment cells. Multiple combinations of targeted therapies and immunotherapy for cancer are being tested in the clinic, in what is becoming an area of high interest for future cancer therapy. 10:30 a.m. Introduction 10:40 a.m. Immune cells as targets for pathway inhibition Nicholas P.

Cheresh, UCSD Moores Cancer Center, La Jolla, CA Even the most effective cancer therapies are limited due to the development of one or more resistance mechanisms. Acquired resistance to targeted therapies can, in some cases, be attributed to the selective propagation of a small population of intrinsically resistant cells. However, there is also evidence that cancer drugs themselves can drive resistance by triggering the biochemical- or geneticreprogramming of cells within the tumor or its microenvironment. Therefore, understanding drug resistance at the molecular and biological levels may enable the selection of specific drug combinations to counteract these adaptive responses. This symposium will explore some of the recent advances addressing the molecular basis of cancer cell drug resistance. We will address how tumor cell signaling pathways become rewired to facilitate tumor cell survival in the face of some of our most promising cancer drugs. Another topic to be discussed involves how drugs select for or induce the reprogramming of tumor cells toward a stem-like, drugresistant fate. By targeting the molecular driver(s) of rewired signaling pathways and/or cancer stemness it may be possible to select drug combinations that prevent the reprogramming of tumors and thereby delay or eliminate *An extended abstract for this presentation is available in the Invited Abstracts section of the Proceedings (the abstract number is listed in brackets above). **NextGen Star, selected to give a talk by the AACR President and Annual Meeting Program Chairperson through a competitive application process designed to bring more visibility to early-career scientists.

Guarente, Massachusetts Institute of Technology, Cambridge, MA Over the past 20 years, several metabolic pathways have been identified that control the rate of aging in experimental animals – sirtuins, IGF signaling, AMPK, and mTOR. Interestingly, these pathways all play important roles in cancer metabolism. This session will feature talks on sirtuins and NAD, PI3K/PTEN of the IGF pathway, and mTOR as they relate to metabolism, aging, and cancer. The sirtuin SIRT1 and its cosubstrate for deacetylation, NAD, will be related to circadian control and aging, and shown to decline functionally with aging with deleterious consequences. SIRT6 will be discussed as a tumor suppressor via its repression of the Warburg effect. mTOR will be discussed as a sensor of amino acids to set the rate of protein synthesis, cell growth, and aging. Finally, PI3K/PTEN, a major pathway in cancer, will be related to aging and disease. All told, these key metabolic pathways can be seen in a biological context affecting not only cancer, but aging and diseases as well. 10:30 a.m. Introduction 10:40 a.m. Sirtuins and NAD link metabolism and health Leonard P.

Strides forward in analysis of circulating tumor DNA (ctDNA) have culminated in increased sensitivity and regulatory approval of a ctDNA based companion diagnostic of EGFR mutation status. This session showcases the power of ctDNA as a routine clinical management tool and notably, to chart emergence of resistance mechanisms to targeted treatments. Although the technical challenges are greater, the molecular analysis of circulating tumor cells (CTCs) offers additional scope as a “liquid biopsy,” where cell-tocell heterogeneity can be explored and where evaluation of single CTC DNA, RNA, and proteins can be undertaken. With development of marker independent CTC technologies, the technical challenges are being met and clinical CTC based biomarkers are continually emerging. Recent progress also now includes the culture of viable CTCs both in vitro and in vivo offering exciting new avenues for translational cancer research. 10:30 a.m. The versatility of CTCs in lung cancer: Biomarkers, biology, mouse models, and drug development Caroline Dive, Paterson Institute for Cancer Research, Manchester, United Kingdom Chairperson: Robert G. Bristow, University Health Network Princess Margaret Hospital, Toronto, ON, Canada The presence of a potential oligometastatic disease in which limited nonprimary anatomic sites are involved without widespread synchronous metastases can be a staging and therapeutic dilemma. If the disease is truly limited to definable sites, then patients may be cured of their disease by combining treatment of the primary with the ablation of macrometastases (using surgery or stereotactic ablative radiotherapy (SABR)) and adjuvant systemic treatment. But defining exactly which patients and which diseases will benefit from such aggressive treatment remains elusive. In this session, we will review the clinical evidence for oligometastases and the response to SABR and surgery across different tumor types. It will also describe technical issues pertaining to such ablation. The session will also discuss potential molecular signatures that can predict the presence or absence of oligometastatic disease using DNA and RNA and miRNA indices. The session will end with a panel discussion regarding future research and opportunities for clinical trials to drive precision cancer medicine in oligometastatic patients. 10:30 a.m. Clinical radiobiology metastases Paul Okunieff, University of Florida Shands Cancer Center, Gainesville, FL 10:50 a.m. Discussion 10:55 a.m. Molecular signatures for oligometastases in prostate cancer: A default approach Robert G.

Chairperson: Timothy R. Rebbeck, University of Pennsylvania School of Medicine, Philadelphia, PA Differences in biomarkers, risk factors, clinical features, and outcomes across groups can inform cancer etiology. Extreme differences, such as those seen among widely divergent populations, may be particularly informative if they capture the maximal variation that may exist. Knowledge gained from these population differences may be translated into precision prevention or treatment that can target specific subpopulations of individuals. This session will review the features of breast cancer across populations to identify features that may hallmark common markers of risk or outcome that may be universal to all breast cancer. The session will also identify population-specific features that may inform prevention and treatment in specific groups of women. 10:30 a.m. Global cancer research: What can we learn from differences across populations?

Baker, St. Jude Children’s Research Hospital, Memphis, TN Tumors of the nervous system in children are associated with significant morbidity and mortality, and comprise a heterogeneous spectrum of disease. Despite similarities with adult disease in some histopathological and clinical features, genome-wide sequencing studies have revealed striking differences in the mutation spectrum of pediatric brain cancer, illuminating a critical connection between developmental context and the selective pressures driving tumorigenesis at different ages. This session will focus on the latest advances in understanding the mechanisms underlying several different types of brain tumors in children, including discussions of molecular classification, the contribution of cellular and developmental context, and the therapeutic implications of these findings for this devastating collection of pediatric cancers. 10:30 a.m. Genetic and epigenetic drivers of pediatric high-grade glioma Suzanne J.

Taylor, University of Toronto Hospital for Sick Children, Toronto, ON, Canada Chairperson: Hedvig Hricak, Memorial Sloan Kettering Cancer Center, New York, NY The imaging armamentarium for prostate cancer has expanded beyond anatomical imaging. Multiparametric MRI is gaining acceptance; PET tracers, such as C-11 choline, F-18 choline, and PSMA-targeting ligands are emerging; and new modalities, such as MR/PET and hyperpolarized MR, are entering the clinical arena. These tools have great potential for addressing the most stubborn diagnostic challenges that affect prostate cancer management, such as distinguishing insignificant from lifethreatening disease, detecting a recurrent tumor early, and distinguishing local recurrence from metastasis. These tools should help us better understand the mechanisms of prostate cancer progression, enable the development of new, minimally invasive treatments, targeted therapies and theranostics, and ultimately improve patient outcome. However, standards for applying even widely used imaging methods have yet to be established, and many fundamental issues remain to be addressed. This session will review exciting advances in prostate cancer imaging and image-guided therapy while also discussing important knowledge and practice gaps. 10:30 a.m. Multimodality imaging of primary and metastatic prostate cancer: Advances, gaps, and limitations Hedvig Hricak, Memorial Sloan Kettering Cancer Center, New York, NY 10:50 a.m. Discussion 10:55 a.m. Advances in MRI diagnostics Masoom A.

MicroRNAs (miRNAs) are a class of small ncRNAs that function as important posttranscriptional regulators of gene expression in most, if not all, biological processes. Furthermore, many miRNAs play key roles in the pathogenesis of cancer and have been implicated either as oncogenes or tumor suppressors in a wide range of malignancies. These findings underscore the potential of miRNAs as a new class of targets for cancer therapeutics. Long ncRNAs (lncRNAs) comprise a highly diverse group of ncRNAs greater than 200 nucleotides in length, with emerging roles in cancer biology. This session will focus on the functions of miRNAs and lncRNAs in the pathogenesis of liver cancer and describe recent progress in the discovery and development of ncRNA-based cancer therapeutics. 10:30 a.m. Long noncoding RNA in liver cancers Tushar Patel, Mayo Clinic Cancer Center Jacksonville, Jacksonville, FL 10:50 a.m. Discussion 10:55 a.m. Role of microRNA-122 in liver homeostasis and hepatocellular carcinoma Kalpana Ghoshal, The Ohio State University, Columbus, OH 11:15 a.m. Discussion 11:20 a.m. Approaches for therapeutic modulation of microRNA activity Sakari Kauppinen, Aalborg University Hospital, Copenhagen, Denmark 11:40 a.m. Discussion 11:45 a.m. Preclinical and clinical development of microRNA-34 mimic, MRX34, for treatment of liver cancer David S.

Elion Cancer Research Award Lecture The Role of Serine Metabolism in Melanoma Matthew G. Vander Heiden, MD, PhD MIT Koch Institute for Integrated Cancer Research, Cambridge, MA The AACR Gertrude B. Elion Cancer Research Award provides a one-year grant to foster meritorious basic, translational, or clinical cancer research by a tenure-track scientist at the level of Assistant Professor. This award honors the late Dr. Gertrude B. Elion, Scientist Emeritus at Glaxo Wellcome Co. (now GlaxoSmithKline). Her seminal research at the company revolutionized cancer therapeutics and her prolific contributions to biomedical science earned her the Nobel Prize in Physiology or Medicine in 1988. The AACR is extremely pleased to sponsor this award in the name of Dr. Elion, a distinguished Past President and Honorary Member of the AACR. This year we honor Dr. Matthew G. Vander Heiden, who is studying how serine metabolism contributes to melanoma initiation and progression. Altered metabolism is a poorly understood feature of many cancers that holds great promise for improved therapy. However, to successfully target metabolism requires an understanding of how metabolic regulation provides an advantage for tumor cells. Most knowledge of cancer metabolism is based on studies from cultured cells where conditions are different from those experienced by tumor cells in vivo. Thus, better models to study cancer metabolism in vivo have been a limitation for the field. Recently, several studies have converged on serine production from glucose as an important metabolic pathway for cancers. Increased serine synthesis is critical for cancer cell proliferation, and many cancer signaling pathways influence serine metabolism. However, increased production of serine is necessary for cancer cells even when serine is abundant, and why increased serine synthesis is still important is not understood. The gene encoding the first enzyme of the serine biosynthesis pathway, PHGDH, is amplified in human melanoma and allows cancer cells to increase serine production from glucose. Because PHGDH enzyme levels regulate serine synthesis, these studies generated a mouse April 18-22, 2015 • Philadelphia, PA model to control PHGDH expression and study the impact of this pathway on melanoma progression and metabolism. Using transgenic mice with tissue specific, doxycyclineinducible PHGDH expression, Dr. Vander Heiden’s lab found that increased PHGDH expression alone appears insufficient to cause cancer, but does result in inappropriate melanin accumulation in the skin of these mice. When crossed to a mouse melanoma model based on mutant BrafV600E expression and Pten loss that is relevant to human melanomas, they find that PHGDH expression can accelerate tumor growth. In addition, while expression of mutant BrafV600E results in nevi that do not progress to invasive melanoma, PHGDH-expression can cooperate with BrafV600E to cause invasive melanoma. These data argue that PHGDH expression and increased serine biosynthesis can promote the initiation and progression of melanomas and provide the foundation for studies into how altered serine metabolism affects tumor biology. Dr. Vander Heiden is the Eisen and Chang Associate Professor of Biology at the Koch Institute at MIT, and is also an Instructor of Medicine at the Dana-Farber Cancer Institute and Harvard Medical School. Dr. Vander Heiden received his MD and PhD from the University of Chicago. He also completed clinical training in Internal Medicine and Medical Oncology at the Brigham and Women’s Hospital/Dana-Farber Cancer Institute and is a practicing medical oncologist. 497 13_15AM_Tue_Layout 1 3/27/15 12:24 PM Page 498 RECENT ADVANCES IN DIAGNOSTICS AND THERAPEUTICS RESEARCH Dedicated to the Memory of Eddie Reed Tuesday, 12:30 p.m.-3:00 p.m. Room 121, Pennsylvania Convention Center 12:30 p.m. Remembering Dr. Eddie Reed Bruce A.

Dr. Reed, a world-renowned cancer expert, was an AACR member for 27 years (since 1987) and served on numerous boards and committees, including the board of directors and served as chair of the Minorities in Cancer Research (MICR) Council. Dr. Reed was known internationally in the cancer research field for his two interests, cancer drug development and cancer care for the underserved. His clinical research primarily focused on DNA damage and repair in cancer cells. Dr. Reed was recognized as an authority on the actions and use of the anticancer agents paclitaxel and cisplatin, and collaborated on many public health cancer prevention, screening, and control programs. Prior to his recruitment to the NIMHD in 2012, which was established in an effort to improve minority health and eliminate health disparities, Dr. Reed was a professor of oncologic sciences and the Abraham Mitchell distinguished investigator at the University of South Alabama Mitchell Cancer Institute in Mobile. He had served as chief of the pharmacology branch and chief of the Ovarian Cancer and Metastatic Prostate Cancer Clinic in the Division of Clinical Science at the NCI; he was the first African American branch chief to serve at the institute. He had also served as director of the Mary Babb Randolph Cancer Center at West Virginia University in Morgantown, and director of the Division of Cancer Prevention and Control at the Centers for Disease Control and Prevention in Atlanta. Dr. Reed was a very active AACR member; in addition to his election to the board of directors and MICR Council chair, he also served on the MICR-Jane Cooke Wright Lectureship Award Committee and the Research Grant Review Committee. Additionally, he served on the Cancer Prevention Research and Molecular Cancer Therapeutics editorial boards, and was a member of several other committees, including the Annual Meeting 2011 Program Committee and the Award for Lifetime Achievement in Cancer Research Committee. Dr. Reed had also served on the National Advisory Council on Minority Health and Health Disparities and on the Institute of Medicine’s National Cancer Policy Forum.

June, Abramson Cancer Center of the University of Pennsylvania, Philadelphia, PA Chairperson: Jan M. Van Deursen, Mayo Clinic, Rochester, MN Adoptive cell therapy has emerged as an important modality in the treatment of cancer. Over the past several years several centers have demonstrated long lasting effects in patients with advanced cancer. The modalities primarily consist of infusions of autologous tumor infiltrating lymphocytes or redirected T cells that have been engineered to have new specificities using various forms of gene transfer. For the first time the biotechnology and pharmaceutical industries have significant investments in this field. Late stage trials are underway that could lead to widespread commercial approval for various forms of B cell leukemia and lymphoma. This session will elaborate on the progress being made in laboratory and clinical studies to take these therapies to the next level. This includes talks on next-generation chimeric antigen receptor designs, therapy with enhanced T cell receptors and strategies to overcome checkpoint inhibition following adoptive transfer. Cellular senescence has historically been viewed as an irreversible cell-cycle arrest mechanism that acts to protect against cancer, but recent discoveries have expanded its role into complex biological processes such as development, tissue repair, aging, and age-related disorders. Furthermore, it is becoming increasingly clear that senescence may not represent a static state but instead a series of progressive and phenotypically diverse cellular states acquired after the initial cell-cycle arrest. The symposium on senescence and aging will focus on new insights into the molecular mechanisms underlying the multistep progression of senescence, the compositions of senescence-associated secretomes and their autocrine and paracrine effects, the tumor promoting properties of senescent cells, and the development of anti-senescent cell therapeutics for treatment of age-related disorders and diseases. 1:00 p.m. Introduction 1:00 p.m. Introduction 1:10 p.m. 1:10 p.m. TCR-engineered T cells: Can they catch CARs?

Computational systems biology approaches that use multiple omic based data to predict biology along with novel experimental systems that better represent human in vivo biology are proving useful in bridging this gap. This session will integrate a variety of omic-based approaches to model tumor complexity and predict response to inhibitors in the clinic. These include large scale integration of genomic data with phosphoproteomic data to identify metabolism proteome signatures in lung cancer, development of mechanisms of resistance and the integration of mathematical modeling to predict disease response. The potential application of systems biology and the future evolution of the field will significantly affect understanding of cancer disease mechanisms and the ability to devise effective therapeutics. 1:00 p.m. Introduction 1:10 p.m. Evolutionary mathematical modeling allows identification of optimum treatment schedules in lung and brain cancer Franziska Michor, Dana-Farber Cancer Institute, Boston, MA 1:25 p.m. Discussion 1:30 p.m. Integrated omic analysis of lung cancer reveals metabolism-proteome signatures with prognostic impact Michael F.

Jonathan Drachman will focus on efforts to evaluate ADCs in novel clinical trials as well as technological improvements designed to enhance linker stability, pharmacokinetic properties, and payloads. Paul Polakis will highlight clinical and preclinical experiences with ADCs that underscore the complexities associated with their development. Anna Wu will discuss advances in radiolabeling of antibodies and antibody fragments for preclinical and clinical evaluation of novel targets. Dario Neri will discuss immunocytokine fusion molecules, focusing on preclinical and early clinical results as a method of targeting immune activation to the tumor. Chairperson: Samuel Achilefu, Washington University School of Medicine, St. Louis, MO The use of optical imaging methods in the operating room for real-time image-guided surgery has received tremendous interest because of the ease of image acquisition, real-time image projection, detection of cancer with high accuracy, and relatively low-cost devices that do not disrupt surgical workflow. To improve imaging depth and minimize interference by tissue autofluorescence, these methods typically utilize near-infrared (NIR) fluorescent light, which is invisible to human eyes. This symposium will highlight advances in fluorescence imaging devices and emerging tumor-avid molecular probes for intraoperative tumor detection, resection, and real-time surgical margin assessment. Discussion will include practical considerations, challenges to clinical translation of molecular probes to clinics, and strategies to overcome them. 1:00 p.m. Introduction 1:10 p.m. Fluorescence image-guided cancer resection: From bench to bedside Samuel Achilefu, Washington University School of Medicine, St. Louis, MO 1:00 p.m. Introduction 1:10 p.m. The next generation of ADCs [SY35-01]* Jonathan G.

Velculescu, Johns Hopkins Kimmel Comprehensive Cancer Center, Baltimore, MD Chairperson: Gerard I. Evan, University of Cambridge, Cambridge, United Kingdom Analyses of cancer genomes have revealed mechanisms underlying tumorigenesis and new avenues for personalized therapeutic intervention. Nevertheless, there is great complexity in the alterations of individual tumors and a realization that these can change during disease progression. This session will focus on new technologies that have emerged to analyze molecular alterations in the circulation of cancer patients, including as circulating tumor cells, cell-free tumor DNA, and exosomal nucleic acids. These approaches have important implications for noninvasive detection and monitoring of human cancer, therapeutic stratification, and identification of mechanisms of resistance to targeted therapies. The importance of Myc to human cancer is incontestable. The great majority of adult human cancers of all types exhibit demonstrable Myc elevation or deregulation, implicating aberrant Myc expression as pivotal, potentially obligate, in the genesis and evolution of neoplasia. Whether this makes Myc a suitable candidate for pharmacological targeting, however, remains uncertain: we still have no clear understanding of what Myc contributes to cancers – whether this contribution is essential for tumor evolution and/or tumor maintenance, or how bad might be the side effects caused by systemic Myc inhibition. This session explores a variety of innovative genetic, pharmacological, and biochemical strategies to answer these questions. 1:00 p.m. Introduction 1:00 p.m. Introduction 1:10 p.m. Characterization of circulating tumor cells Daniel A.

Green, St. Jude Children’s Research Hospital, Memphis, TN As in cancer, the metabolic reprogramming of T lymphocytes following activation dictates their proliferation, differentiation, and function. Understanding this reprogramming gives insights into cell metabolism in general, and provides opportunities for the manipulation of T cell function in immune therapies. In this session several aspects of T cell metabolism will be explored. Steven Bensinger will discuss how the mechanisms underlying how cholesterol and fatty acid metabolic pathways control immune cell function and host immunity. Shao-Cong Sun will explore how T cell receptor signaling, coupled with the function of a glutamine transporter, influences TORC1 activation and function during T cell activation. Douglas R. Green will describe the process of asymmetric T cell division, and how metabolic events, TORC1, and c-Myc interact asymmetrically to maintain and direct T cell function and differentiation. Finally, Jonathan Powell will consider the influence of the tumor microenvironment on T cell metabolism, and how this can be manipulated to promote antitumor immunity. 1:00 p.m. Regulating host immunity through reprogramming of sterol metabolism Steven Bensinger, University of California, Los Angeles, CA 1:20 p.m. Discussion 1:25 p.m. New insights into mTORC1 signaling in T cells Shao-Cong Sun, The University of Texas MD Anderson Cancer Center, Houston, TX 1:45 p.m. Discussion 1:50 p.m. Metabolic maintenance of asymetric divisiion of T cells Douglas R.

Colditz, Washington University, St. Louis, MO This session brings together new insights to risk factors for breast cancer such as mammographic density and the use of computational pathology to refine risk assessment in benign breast disease. How we approach new risk factors from a quantitative perspective is important, as we strive to integrate scientific advances into models and improve their performance. Ideally models will allow us to stratify cancer risk more precisely and refine population subgroups where risk-benefit tradeoffs are maximized in favor of benefits. Examples of breast cancer incidence models and their translation to clinical use will be presented as a basis for considering the refinement of risk and potential population health impact of scientific advances. 1:00 p.m. Translating models of breast cancer incidence to clinical, stratifying screening for population health Graham A.

Capecchi, University of Utah, Salt Lake City, UT Soft tissue sarcomas are a major cause of morbidity and mortality among children, adolescents, and young adults with cancer, and not insignificant among older adults. Advances in genomics, patient-derived xenograft (PDX) techniques, and conditional mouse modeling are shedding light on not only the biology of this spectrum of cancers, but also the potential therapeutic options. Unlike epithelial cancers, sarcomas may be a prime example where cell of origin and the state of differentiation explain the genomic aberrations as well as the options for epigenetic therapeutic interventions. Increased attention to the basic science of tumor initiation and progression (via genetically engineered mouse models), as well as diversifying the range of human PDX models, may inform and improve clinical trial design which has hereunto been largely empirically based and for which few targeted therapies have resulted in long-term survival benefit. Chairperson: Ben Z. Stanger, Abramson Cancer Center of the University of Pennsylvania, Philadelphia, PA In addition to cancer calls, tumors contain non-mutant stromal cells – fibroblasts, leukocytes, and endothelial cells – that influence tumor behavior. In pancreatic cancer, the stromal compartment makes up a large percentage of tumor bulk, comprising more than 70-80% of total tumor mass and leading to what is histologically termed a “desmoplastic” stroma. Many functional properties have been attributed to the pancreatic tumor stroma, including the notion that fibroblasts act as a barrier to the delivery of chemotherapy and the idea that the tumor builds an immunosuppressive microenvironment early in tumor progression. In this session, our speakers will discuss their own findings and evolving work in the field, providing insight into the promise, and risk, of targeting the tumor stroma in this disease. 1:00 p.m. Pro-inflammatory cytokines in pancreatic cancer pathogenesis Steven D.

Large-scale, tumor-profiling efforts have revealed similarities in mutation prevalence across different cancer types, potentially indicating similarities in tumor development pathways and/or mutations of significance in tumor growth. These findings could inform and optimize use of targeted therapies in multiple indications and disease settings. NGS technologies are also being utilized in the clinical setting as screening tools for large, multi-arm, investigational studies, as well as companion diagnostics to choose from multiple targeted therapies. The transition of NGS from the research setting into the clinical setting to direct treatment of patients raises exciting new possibilities while simultaneously raising translational, regulatory, and reimbursement concerns. While NGS technologies hold much promise for the realization of precision medicine in the clinic, there are uncertainties with regards to evidence development for analytical validity, clinical validity, and clinical utility of these tests. This session, will discuss strategies to optimize evaluating the clinical validity and utility of NGS based tests, the U.S. Food and Drug Administration’s current thinking on regulation of NGS-based tests as well as payer perspectives on coverage and reimbursement of tests. A panel discussion will be moderated by Laura J. van 't Veer, UCSF Helen Diller Family Comprehensive Cancer Center, and audience Q and A will follow the presentations.

Stevens and Paul C. Pearlman, National Cancer Institute-CGH, Rockville, MD The NCI Center for Global Health (CGH) is committed to strengthening cancer research and cancer control planning in a manner that is sustainable beyond the NCI funding. Our research efforts have been focused on a limited number of topics that are relevant to international investigators. These areas include cancers associated with chronic infection, ecological-niche cancers (cancers with a high incidence in a region or country), high-burden cancers, tobacco control, and implementation science. CGH recently funded projects to study the application of low-cost technologies in specific settings via a translational research program to adapt, engineer, and apply low-cost and point-of-care cancer technologies in Low- and Middle-Income Countries (LMICs) settings. During the three years that the Center has existed, there have been a limited number of funding opportunities to develop this type of capacity in LMICs. The intention is to grow the funding opportunities for research within these LMIC settings (through partnerships) and to increase the mentoring of scientists in grant and scientific writing, experimental design, and utilization of data to inform policy (where appropriate). CGH staff work across NCI to engage scientific experts and intend to continue to increase the engagement of the scientific community in our efforts. We hope to tap into the scientific expertise of our Cancer Centers, University partners, and AACR members as our programs continue to grow. Program highlights include: 1) Low-Cost Technology Request for Applications: status and organization of the program, projects funded in the first round, evaluation plan, focus for round two; 2) Pilot Projects for Cancer Centers in Research, Training, and Capacity Building: projects funded and regions served, plans for round two, evaluation plan; 3) Bilateral funding initiatives: U.S.-China, U.S.-South Africa, U.S.-Brazil and future opportunities; activities funded to date and scope of planned re-issuances; Speakers: Lisa M.

Low, PhD Director of the Purdue Center for Drug Discovery Ralph C. Corley Distinguished Professor Purdue University, West Lafyette, IN The AACR and its Chemistry in Cancer Research Working Group established the Outstanding Achievement in Chemistry in Cancer Research Award in 2007 to recognize the importance of chemistry in advancing cancer research. The Award is presented for outstanding, novel chemistry research that has led to significant contributions to the fields of basic or translational cancer research, cancer diagnosis, prevention, or clinical cancer treatments and therapeutics. Dr. Philip S. Low, currently the R.C. Corley Distinguished Professor of Chemistry at Purdue University and the Director of the Purdue University Center for Drug Discovery, is recognized for his pioneering use of low-molecular-weight targeting ligands for selective delivery of attached therapeutic and imaging agents into cancer cells. His contributions to the development of these drugs have led to dramatic improvements in therapeutic potency, reductions in drug toxicity, and increased companion diagnostic applications such as whole body imaging and fluorescence-guided surgery. This work has motivated fundamental changes in the practice of surgery and medicine. Dr. Low’s accomplishments epitomize the importance of chemistry in cancer research. Dr. Low and coworkers discovered the ability of folate to carry attached payloads into cancer cells that express folate receptors (FR) in 1989. After characterizing the intracellular trafficking of FR in cancer cells, and determining expression levels of FR in various tumors, Dr. Low and coworkers developed folate-linked imaging agents for identification of patients with FR+ tumors and folate-linked cytotoxic drugs for treatment of patients with FR+ cancers. In contrast to classical drugs that distribute indiscriminately into all cells of the body, Dr. Low’s small molecule targeting approach concentrates the attached cargo (chemotherapeutic agent, liposome, siRNA, enzyme-activated prodrug, gene therapy vector, imaging agent (PET, MRI, SPECT), etc.) specifically in the diseased tissue, thereby avoiding collateral toxicity to normal tissues. Development of the tumor-targeted drugs to date has led to eight drugs in current human clinical trials for ovarian, lung, kidney, and prostate cancers, and additional ligand-targeted drugs in preclinical development for treatment of other cancers and inflammatory/autoimmune diseases. Ligand-targeted therapies for viral and other infectious diseases are also undergoing preclinical development. Dr. Low earned his BS degree from Brigham Young University in 1971 and his PhD from the University of California, San Diego in 1975. After postdoctoral work at the University of Massachusetts he joined the faculty at Purdue in 1976. Dr. Low has won multiple awards including this year’s American Chemical Society’s Award for cancer research (Sosnovsky Award) and is the founder of Endocyte Inc., On Target Laboratories LLC, and HuLow LLC, which have advanced discoveries around receptor targeting to clinically useful drugs. 548 AACR ANNUAL MEETING 2015 13_15AM_Tue_Layout 1 3/27/15 12:24 PM Page 549 AACR-ACS AWARD LECTURE Tuesday, 3:00 p.m.-4:00 p.m. Grand Ballroom (300 Level), Pennsylvania Convention Center Twenty-Fourth Annual AACR-American Cancer Society Award for Research Excellence in Cancer Epidemiology and Prevention Risk Models and Cancer Prevention Mitchell H.

Van Der Burg, Leiden University Medical Center, Leiden, The Netherlands; Cedrik M. Britten, GlaxoSmithKline, Stevenage, United Kingdom The aim of this session that is jointly organized by the AACR Cancer Immunology (CIMM) Working Group and the Association for Cancer immunotherapy (CIMT) is to cover two innovative areas of immune-oncology that bear the potential to give rise to next waves of treatments in the coming years. The session will provide insight into how the adaption of clinical-grade genomics and bioinformatics tools into translational oncology may open the stage for novel concepts for personalized medicine. The second part of the session will focus on the topic of local immunity which may play a critical role in determining whether pharmacologically active immune-therapeutic treatments will be able to induce killing of tumor cells in vivo. The promise is that a greater understanding of the hurdles and druggable switches within the tumor microenvironment will enable development of novel treatments or rational combinations of compounds with increased efficacy. 3:00 p.m. An integrative network approach for genomic discovery and personalized therapy in relapsed multiple myeloma Joel Dudley, Icahn School of Medicine at Mount Sinai, New York, NY 3:25 p.m. Discussion 3:30 p.m. Characterization of cancer immunophenotypes and antigenomes using NGS data and bionformatics methods Zlatko Trajanoski, Innsbruck Medical University, Innsbruck, Austria 3:55 p.m. Discussion 4:00 p.m. Building effective immunotherapy: Lessons learned from ovarian cancer George Coukos, University Hospital of Lausanne, Lausanne, Switzerland 4:25 p.m. Discussion 4:30 p.m. The role of the p53 protein in epigenetic regulation and the innate immune response Arnold J.

Siu, University Health Network Princess Margaret Hospital, Toronto, ON, Canada; Xuchao Zhang, Guangdong Academy of Medical Sciences, Guangzhou, P.R. China The identification of valid predictive biomarkers is a key step to unravel the biological complexity of cancer. Predictive biomarkers form the basis of precision medicine by providing information related to the effects of specific treatments, and thus enabling the selection of patients who are most or least likely to benefit. Advances in massive parallel sequencing of cancer genomes have revealed that individual tumors frequently harbor driver somatic mutations and other molecular aberrations that confer growth advantage and positive selection. Some of these aberrations represent therapeutic targets of approved or investigational anticancer agents, and may ultimately become predictive biomarkers of sensitivity or resistance to these compounds if antitumor activity can be demonstrated. Numerous national and international efforts are actively ongoing to elucidate the value of genotype-matching with molecularly targeted agents. In addition to targeted therapeutics, recent evidence reveals that genome sequencing can also provide insight to identify responders to immune checkpoint inhibitors such as CTLA and PD-1/PD-L inhibitors through the identification of neoantigen signature, analysis of TCR repertoire, etc. This session will highlight the use of genome sequencing technologies to identify predictive biomarkers for targeted and immune therapeutics. 3:00 p.m. Clinical application of genome sequencing to identify genotype-matching therapy Lillian L.

Gerhard, National Cancer Institute, Bethesda, MD The goals of the NCI’s Cancer Target Discovery and Development (CTD2) Network are to bridge the gap between the enormous volumes of data generated by multiple efforts for the genomic characterization of cancer and the ability to use these data for the development of human cancer therapeutics. It specializes in computational and functional genomics approaches critical for translating next-generation sequencing data, including those generated by the TCGA, TARGET, and ICGC consortia. Specifically, the CTD2 network deploys a variety of innovative high-throughput and integrative approaches that combine the power of computational systems biology, functional screens, and large-scale chemical profiling approaches to discover, characterize, and validate novel cancer drug targets, including novel genetic drivers and non-oncogene dependencies that can be targeted by small molecules or immunotherapy. This includes targets for combination therapy and for the development of compounds that rescue sensitivity to existing standard of care oncology drugs. These approaches are designed to match targets to relevant cancer phenotypes and genotypes, thus providing companion biomarkers supporting efficient patient stratification for more targeted clinical trials. The presentations highlight the breadth of approaches and translational potential employed by Network Centers. The session starts with a brief introduction to CTD2 and its mission and resources. http://ctd2.nci.nih.gov/ 552 AACR ANNUAL MEETING 2015 MINISYMPOSIUM Tuesday, 3:00 PM-5:00 PM Terrace Ballroom IV (400 Level), Pennsylvania Convention Center Room 121, Pennsylvania Convention Center Clinical Research Precision Medicine in the Clinic Molecular Endocrinology of Breast and Prostate Cancer Chairpersons: Pasi A.

Rubin, Merck Research Laboratories, North Wales, PA Given our improving understanding of the genetic and molecular underpinnings driving cancer growth, it is often possible to hypothesize that a specific population of patients will be uniquely responsive to a new drug. However, development of companion diagnostic assays often lags behind development of new therapeutics, and there may be uncertainty in key aspects of an assay, such as the cutoff defining a “positive” test. The U.S. Food and Drug Administration (FDA) guidance “Enrichment Strategies for Clinical Trials to Support Approval of Human Drugs and Biological Products” includes a discussion of an approach in which a predictive biomarker is identified during (not before) a phase III trial. This approach involves the enrollment of “all comers” without stratification, but with a prospectively defined retrospective analysis that controls type I error. Use of this approach has the potential to accelerate development of optimal diagnostic tests that can be used to identify uniquely responsive patients. This session will discuss: • The criteria for designing a prospectively defined retrospective study, • Potential modification of a trial to enrich for a specific population, • The statistical considerations for study design, as well as • Developing companion assays for biomarker identification. The session will also include the FDA’s perspective on Agency expectations for conducting such studies. A panel discussion moderated by Eric H. Rubin, Merck Research Laboratories, and audience Q and A will follow the presentations. Speakers: Eric H. Rubin, Merck Research Laboratories, North Wales, PA Geoffrey S.

Rothenberg, Pfizer, Inc., New York, NY; Tatiana M. Prowell, U.S. Food and Drug Administration, Silver Spring, MD, and Johns Hopkins Kimmel Cancer Center, Baltimore, MD The U.S. Food and Drug Administration (FDA) has a number of programs intended to hasten the development and approval of safe and effective therapies for patients, including fast track designation, breakthrough therapy designation, priority review, and accelerated approval. The Agency recently issued final guidance on the differences and applicability of each of these programs, titled “Expedited Programs for Serious Conditions – Drugs and Biologics.” These programs impact drugs at virtually every stage of development and are designed to streamline the process by which safe and effective new agents receive regulatory approval and may be made available as quickly as possible to treat patients with serious and life-threatening diseases. It is recognized that under these conditions, new drugs will be introduced into the market based on compelling data generated by clinical trials that may have been relatively small in size, conducted without a concurrent control arm, and/or lacking long term follow up. The impact of expedited development and the level of clinical evidence available at the time of approval will be discussed from various perspectives including those of patients, clinicians, regulators, industry, and others. This session will use case studies to illustrate the scientific and regulatory considerations to strategically employ expedited programs in oncology drug development. Discussion topics will include: I. Expedited approval and the impact on patient care: a) How ready are practicing oncologists to embrace new drugs that are approved via expedited pathways; b) How does expedited approval impact payment and reimbursement; c) What are the concerns of clinicians (private practice and academic); patients and payers regarding uptake of drugs approved via expedited pathways? II. Expedited approval and the impact on drug development: a) Impact on the development of other agents in class; b) Impact on the drug’s development for other indications; c) Impact on other drugs in development (other sponsors and sponsor’s own pipeline) III. Secondary Impacts of expedited approvals: a) Criteria for expedited approval in other parts of the world; b) Impact on the drug’s development in regions with differing standards for approval; c) Perception of unmet need and level of urgency for new drug approval in different parts of the world Speakers: Mace L.

Vakoc, MD, PhD Cold Spring Harbor Laboratory, Cold Spring Harbor, NY Since 1979, the AACR Award for Outstanding Achievement in Cancer Research has been given to a young investigator no more than 40 years of age to recognize his or her meritorious achievements within the field of cancer research. Dr. Christopher R. Vackoc is honored for his groundbreaking discoveries in the areas of epigenetics and cancer biology. More specifically, Dr. Vakoc’s work on the basic molecular mechanisms that control leukemias has revealed an essential connection between epigenetic regulation and oncogenesis, and has subsequently led to development of new therapeutic approaches. He brings a high level of precision, creativity, and intensity to his research, and we applaud his efforts in bringing new fundamental insights to the clinic. Dr. Vakoc is recognized for having found that the BET bromodomain protein BRD4 is a specific vulnerability of aggressive forms of acute myeloid leukemia (AML). His work also provided for the first time an opportunity to drug the hitherto undruggable MYC pathway in cancer, as BRD4 is an upstream regulator of MYC. Chris found that an existing BRD4 drug, JQ1, could inhibit MYC and thereby have a therapeutic effect on MYC driven leukemia mouse models. These findings have now progressed into the clinic, where multiple BET domain inhibitors are tested in MYC driven cancers. Earlier in his career, Dr. Vakoc worked in the lab of Gerd Blobel at the University of Pennsylvaina, were he studied members of the mixed-lineage leukemia (MLL) family of proteins – histone modifying enzymes responsible for generating epigenetic marks on chromatin. Chris identified a persistent histone mark he thought could be contributing to the epigenetic reprogramming of these leukemias, an early example of the emerging significance that epigenetics has had in cancer biology. In 2008 Dr. Vakoc joined Cold Spring Harbor Laboratories as a fellow where he followed up on his work at University of Pennsylvania, finding that MLL acts as a “bookmark” to tell daughter cells which genes to express after mitosis. This was a significant finding, as it not only provided a clearer picture of what MLL normally does in healthy cells to promote inheritance of gene expression information, it also provided the basis for future studies directed at understanding how MLL mutations impact these mechanisms in leukemia. Dr. Vakoc received both his PhD and MD degrees from the University of Pennsylvania (in 2005 and 2007, respectively). He joined Cold Spring Harbor Laboratories in 2008, where he currently is an assistant professor. He has received several awards and honors for his work, including the 2011 Burroughs Wellcome Fund Career Award for Medical Scientists, the 2011 Sass Foundation Fellowship and the 2011 Forbeck Scholar Award. 562 AACR ANNUAL MEETING 2015 13_15AM_Tue_Layout 1 3/27/15 12:24 PM Page 563 AACR-BURCHENAL AWARD LECTURE Tuesday, 4:15 p.m.-5:15 p.m. Grand Ballroom (300 Level), Pennsylvania Convention Center Twentieth Annual AACR Joseph H. Burchenal Memorial Award for Outstanding Achievement in Clinical Cancer Research Immunologic Treatments for Pancreatic Cancer: Current and Future Strategies Elizabeth M. Jaffee, MD Johns Hopkins University, Baltimore, MD The Joseph H. Burchenal Memorial Award was established in 1996 to recognize outstanding achievements in the field of clinical cancer research. It is named for the late Dr. Joseph H. Burchenal, honorary member and past president of the American Association for Cancer Research and pioneer in the development of chemotherapeutics for the treatment of cancer. Elizabeth M. Jaffee, MD, is honored for her outstanding contributions to cancer immunology in both the preclinical and early clinical settings. Her pioneering work in immunotherapies for breast and pancreatic cancers has been tremendously influential to the discovery and development of new and effective cancer treatments, providing renewed hope for those afflicted with these terrible diseases. In addition to her remarkable scientific accomplishments, we also applaud her efforts as a mentor for the next generation of researchers and clinicians. Dr. Jaffee is credited with opening the door to immunotherapy as a potential treatment for pancreatic cancer. Her numerous clinical research successes include testing one of the earliest therapeutic pancreatic cancer vaccines (GVAX) in 1997. She has also shown that mesothelin is a viable target for therapeutic vaccines and adoptive therapy for pancreatic cancer. Dr. Jaffee recently led a phase II trial that showed that a GVAX prime and Listeria monocytogenes vaccine boost improved overall survival for patients with pancreatic cancer; this approach was recently granted breakthrough status by the U.S. Food and Drug Administration. Dr. Jaffee is currently leader of the Stand Up To Cancer-Lustgarten Foundation Dream Team: Transforming Pancreatic Cancer to a Treatable Disease. The Dream Team is conducting combination clinical trials and establishing biomarkers of tumor microenvironment reprogramming. The trials focus on novel immune-suppressive pathways within the tumor, either in combination with a T cellactivating vaccine or chemotherapy. Dr. Jaffee is an active AACR member, currently serving on the board of directors, as chair of the Cancer Immunology Working Group, and as co-chair of the Immunology Program Committee at this year’s AACR Annual Meeting. Additionally, she is deputy editor of Cancer Immunology Research and has been active in AACR mentoring programs, including those as part of the Women in Cancer Research Working Group. Dr. Jaffee received her medical degree from New York Medical College in Valhalla and completed an internship and residency at the University of Pittsburgh’s Presbyterian University Hospital. She first came to Johns Hopkins to complete a postdoctoral fellowship in 1989 and joined the faculty in 1992.

Moderator: Benjamin G. Neel, University of Toronto Ontario Cancer Institute, Toronto, ON, Canada The cancer stem cell model of tumor heterogeneity holds that only certain cells within tumors or hematologic neoplasms, termed “cancer stem cells” (CSCs) or “leukemia stem cells” (LSCs), respectively, have the capacity to indefinitely self-renew and generate the remaining bulk tumor. Because CSCs and LSCs are proposed to have distinct properties, they also could have unique vulnerabilities, as well as manifest resistance to conventional agents. Substantial evidence supports a CSC/LSC organization in many malignancies, yet in other cases (e.g., melanoma) all tumor cells appear to have self-renewal/differentiation potential. This session will consider the role of CSC/LSC in leukemia, breast cancer and glioblastoma, with particular focus on therapeutic implications. Panel: Ross L. Levine, Memorial Sloan Kettering Cancer Center, New York, NY Terrace Ballroom IV (400 Level), Pennsylvania Convention Center Challenges in Trial Design for the Genomic Era Moderator: Donna S. Neuberg, Dana-Farber Cancer Institute, Boston, MA The ability to test patient samples for mutations and other anomalies in a timely fashion, coupled with the availability of agents targeted to mutations and aberrant expression, offers great promise in cancer therapy. There are many ways to implement such studies and to measure effect. One can restrict the study population to a particular disease type, but one can also offer treatment based on biology to a more heterogeneous population. Biomarkers are critical for assigning treatment and assessing specificity of effect. Participants will highlight some of the challenges in reworking our established paradigms to address the needs of modern trials in the genomic era. 5:00 p.m. Introduction Donna S.

Dirks, University of Toronto Hospital for Sick Children, Toronto, ON, Canada Room 103, Pennsylvania Convention Center Avatar Mouse Models for Personalized Cancer Treatment Moderator: Manuel Hidalgo, Centro Nacional de Investigaciones Oncológicas (CNIO), Madrid, Spain Strategies to personalize cancer treatment are very important and highly needed. Currently, several biomarkers are routinely used for that goal. For most tumors types and drugs, however, there are no methods for personalized treatment. Over the last few years, there has been interest in using patient-derived xenograft models, aka Avatar mouse models, for this goal. Earlier studies suggest the promise of this approach but important scientific, technical, and logistic issues remain to be solved for broader application of this method. In this session, the current status and future directions of this approach will be discussed. Panel: Giorgio Inghirami, Weill Cornell Medical College, New YorkPresbyterian, New York, NY 564 Room 204, Pennsylvania Convention Center Role of Autophagy in Cancer Development, Progression, and Therapy Moderator: Eileen P. White, Rutgers-The Cancer Institute of New Jersey, New Brunswick, NJ Autophagy is a catabolic process that captures, degrades, and recycles intracellular components to maintain metabolism and survival in starvation and the function and quality of intracellular proteins and organelles. The discovery that autophagy inactivation can selectively compromise the AACR ANNUAL MEETING 2015 13_15AM_Tue_Layout 1 3/27/15 12:24 PM Page 565 growth and survival of some RAS- and BRAF-driven and other cancers has prompted interest in inhibiting autophagy for cancer therapy. Autophagy has also been implicated as a therapy resistance mechanism suggesting that addition of autophagy inhibitors may provide clinical benefit. We will discuss the mechanisms by which autophagy contributes to tumorigenesis, how the role of autophagy differs between tumor types, whether the functional status of autophagy influences treatment response, and the degree to which autophagy inactivation is selectively detrimental to tumor rather than normal tissues. Panel: Alec C. Kimmelman, Dana-Farber Cancer Institute, Boston, MA Jayanta Debnath, University of California, San Francisco, CA Room 126, Pennsylvania Convention Center Value-Based Drug Development Moderator: Ellen V. Sigal, Friends of Cancer Research, Washington, DC Health care has become increasingly complex with the advent of genomic medicine and the downward pressure on costs. As a result, pharmaceutical companies must continue to adapt the drug development process to ensure that, in this complex environment, the drugs produced provide maximum value to consumers. Value-based medicine is at the core of ongoing discussions within the health care community, particularly within the field of oncology, as quality of care, patient outcomes and survival, and access to treatments are of increasing importance. This forum, which will build on the larger discussion about quality and value taking place at the national level, will highlight current research, initiatives, and policy needs to move towards a healthcare system with high-quality care and improved outcomes for patients. The forum will foster a dialogue with leaders in academia, industry, and the patient community to discuss the important role and need for innovation and define the value components necessary for innovative development of targeted therapies that improve patient outcomes. 5:00 p.m. Introduction Ellen V.

Moderator: Johnathan R. Whetstine, Harvard Medical School and Massachusetts General Hospital Cancer, Charlestown, MA Bromodomain inhibition has shown tremendous clinical promise. This session is aimed at asking some key questions about bromodomains and their therapeutic potential. For example, “Are all bromodomains created equal?” and “Are all bromodomain inhibitors acting the same or impacting one universal pathway?” Discussing these types of fundamental questions will foster interactive and thoughtful dialog that will impact our understanding of this area of epigenetic therapy. The discussions within this session will address which bromodomains should be targeted and explore the impact of pan-inhibition versus site-selectivity. The session will also interrogate mechanisms of action. Specifically, discussions will be centered on Myc-dependent and -independent roles between and within tumor types. These discussions are designed at creating a dialog and exchange. The two speakers that are leading this session are Drs.

Molecular diagnostic tests can take two paths to market – via review and approval by the U.S. Food and Drug Administration (FDA) as in vitro diagnostic (IVD) tests or “kits” or as laboratory-developed tests (LDTs). LDTs are tests that are designed, manufactured, and offered within a single laboratory. While the FDA has authority over all diagnostic tests, the agency had historically chosen not to enforce its authority in the case of LDTs because traditionally these were simple, well-established tests. However, LDTs being developed today can be complicated tests that pose a high risk to the patient. Therefore, the FDA has recently proposed a framework detailing a risk-based, phased-in approach to oversee high- and moderate-risk LDTs. This proposal raises many concerns within the laboratory community and the American Association for Cancer Research (AACR) is committed to engaging with the FDA in a constructive dialogue to protect patients, instill physician confidence in the validity of the test results, incentivize innovation, and advance the practice of precision medicine. This town hall session will provide an opportunity for AACR members to interact with the FDA’s leadership on the proposed framework to regulate LDTs. A panel discussion moderated by Laura J. van ‘t Veer, UCSF Helen Diller Family Comprehensive Cancer Center, and audience Q and A will follow the presentations.

Old Award in Cancer Immunology CAR T Cells: Can We Move Beyond B Cells? Carl H. June, MD Abramson Cancer Center of the University of Pennsylvania, Philadelphia, PA The AACR-CRI Lloyd J. Old Award in Cancer Immunology was established in honor of the late Lloyd J. Old, MD, who is considered the “Founding Father of Modern Tumor Immunology.” Dr. Old’s outstanding research in the field of cancer immunology, as well as his decades of leadership in fostering the field, have had a far-reaching impact on cancer. This award is intended to recognize an active cancer immunologist who, like Dr. Old, has done outstanding, innovative, and impactful research in cancer immunology. Dr. Carl H. June is recognized for his important contributions to cancer immunology, specifically his pioneering efforts related to the development of chimeric antigen receptor (CAR) T cell therapy. His work with CAR T cell therapy has significantly enhanced the promise of cancer immunotherapy, evidenced by the recent licensing of this therapeutic by Novartis. This investigational therapy, now called CTL019, has received breakthrough therapy designation from the U.S. Food and Drug Administration for the treatment of relapsed and refractory adult and pediatric acute lymphoblastic leukemia (ALL). This work will not only have a profound impact on the treatment of leukemia but is paving the way for the development of CAR T therapies for other types of cancer. Dr. June has been recognized with numerous honors throughout his career, including the Taubman Prize for Excellence in Translational Medical Science, the Karl Landsteiner Memorial Award from the American Association of Blood Banks, the Steinman Award for Human Immunology Research from the American Association of Immunologists, the Richard V. Smalley Award from the Society of Immunotherapy of Cancer, the Paul Ehrlich and Ludwig Darmstaedter Prize, the Legion of Merit from the U.S. Navy, and election to the Institute of Medicine and the American Academy of Arts and Sciences. A graduate of the United States Naval Academy in Annapolis, MD, Dr. June served as a U.S. Navy Medical Officer from 1975 to 1996. He received his medical degree from Baylor College of Medicine in Houston and completed a research fellowship in immunology with the World Health Organization in Geneva, Switzerland, and a fellowship in oncology at the Fred Hutchinson Cancer Research Center in Seattle. Dr. June performed his internship and residency at the National Naval Medical Center in Bethesda, after which he was appointed professor in the Department of Medicine at the Uniformed Services University of the Health Sciences in Bethesda, MD. He is currently the Richard W. Vague professor in immunotherapy at the Perelman School of Medicine and director of the Translational Research Program at the Abramson Cancer Center of the University of Pennsylvania.
