Establishing a biologic signature of melanoma is complex and challenging but needed to achieve more long-term therapy responses. Developmental pathways are activated in melanoma including pathways related to Notch, Wnt, Shh signaling that lead to a stem cell-like phenotype. Each tumor also contains malignant cell subpopulations that are relatively dormant and poorly amendable to any therapy targeting actively dividing tumor cells. Activated mitochondrial metabolism or normal stromal cells including B cells, macrophages, and endothelial cells provide support for the malignant cells when stressed by drugs. New experimental models such patient-derived xenografts and humanized immune systems in NSG mice, and acquired resistance under continuous drug exposure, are all part of a multifaceted effort to drastically improve strategies for patients’ therapy. Room 204, Pennsylvania Convention Center Clinical Application of Next-Generation Sequencing as a Guide to Treatment Selection biomarkers of response for agents that show profound responses in only a minority of patients. As an example, we explored the molecular basis of an outlier phenotype, an apparent disease cure of a 51-year-old woman with recurrent metastatic small cell carcinoma. The patient was treated on a phase 1 clinical trial that combined topoisomerase I inhibition with an ATP-competitive inhibitor of checkpoint kinase 1 (Chk1). Whole-genome sequencing revealed a complex but highly clonal tumor genome with a somatic, missense mutation in the Mre11 complex gene RAD50, which functions to initiate double stranded break (DSB) repair by homologous recombination or non-homologous end joining. Through modeling in yeast, we confirmed that this heterozygous RAD50 mutation, which affects a highly conserved residue and whose wild type copy was focally deleted, conferred sensitivity to topoisomerase I inhibition. Drug sensitivity was markedly enhanced upon genetic ablation of the DNA damage checkpoint pathway, suggesting a synthetic lethal interaction between checkpoint kinase inhibition and clastogenic chemotherapy. These results and additional examples to be presented demonstrate the feasibility of using whole-genome sequencing in the clinical setting to identify previously occult biomarkers of drug sensitivity that can aid in the identification of patients most likely to respond to targeted anticancer drugs. The use of novel clinical trial designs to confirm genotype-phenotype associations will also be discussed. David B. Solit, Memorial Sloan Kettering Cancer Center, New York, NY Profound and durable responses are often observed in early-stage clinical trials of novel cancer agents in only a small minority of patients. It has long been postulated that these responses have a definable genetic basis but until now it was not feasible to perform a comprehensive genomic analysis of such patients. Rather, at best a few candidate genes were examined. Technical feasibility thus ensured that oncology trials were designed to identify agents that have a statistically significant benefit in a genetically unselected population, a paradigm that has led to the development of many agents that have modest or no benefit in the vast majority of patients. Agents with profound activity in only a small number of patients were on the other had deemed inactive and abandoned. Our preliminary experience shows that next-generation sequencing methodology can now be feasibly applied in the clinical setting to identify previously unrecognized April 18-22, 2015 • Philadelphia, PA 191 11_15AM_Sun_Layout 1 3/27/15 12:20 PM Page 192 MEET-THE-EXPERT SESSIONS Sunday, 7:00 a.m.-8:00 a.m. Room 126, Pennsylvania Convention Center Room 121, Pennsylvania Convention Center Combinatorial Mapping of Vascular Addresses in Cancer: Towards Mechanistic Insights and Targeted Delivery Identifying Metabolic Dependencies of Cancer Cells Renata Pasqualini, University of New Mexico Cancer Research and Treatment Center, Albuquerque, NM Patterns of luminal vascular protein expression vary according to tissue of origin, and these so-called vascular zip codes play an important role in the maintenance of normal physiological processes in multiorgan species. These zip codes are also often modified in response to pathology and play a critical role in the response to and recovery from disease. These differentially expressed proteins offer opportunities for organ- and disease-specific ligand-targeted molecular delivery, offering clear pharmacologic advantages to traditional systemic drug delivery. However, this approach depends on the availability of frequently elusive targets. Combinatorial screening is a valuable tool for identifying optimal ligands for targeted delivery to the vasculature, especially when adapted for in vivo selection. Here we discuss molecular heterogeneity of the vascular endothelium and the use of phage display as a combinatorial screening method to exploit this heterogeneity for tissue or disease-specific vascular targeting. We also highlight applications of this approach for both drug delivery and molecular imaging. Matthew G. Vander Heiden, MIT Koch Institute for Integrated Cancer Research, Cambridge, MA Metabolic regulation influences tumorigenesis and tumor progression. To sustain uncontrolled proliferation, cancer cells must adapt metabolism to support anabolic processes and allow the accumulation of biomass. Survival of cancer cells in inappropriate tissue contexts also requires metabolic adaptation, and understanding the how the metabolic phenotypes of cancer cells support cancer cell proliferation and survival is critical to target these pathways for improved therapy. Approaches to study cancer cell metabolism and identify dependencies that might be exploited for treatment will be described. Studies to understand how glucose and serine metabolism are regulated in cancer cells will be highlighted, together with a discussion of how these pathways modulate both proliferation and survival pathways via effects on nucleotide metabolism. Terrace Ballroom IV (400 Level), Pennsylvania Convention Center New Strategies for Triple-Negative Breast Cancer: Deciphering the Heterogeneity Room 122, Pennsylvania Convention Center Combining Molecularly Targeted Therapies with Chemoradiation Theodore S. Lawrence, University of Michigan, Ann Arbor, MI Chemoradiation is the standard therapy for the majority of locally advanced cancers. However, it is unlikely that improvements in outcome can be achieved by increasing the intensity of either chemotherapy or radiation therapy due to toxicity. Molecularly targeted therapies offer the potential to increase efficacy with little to modest increase in toxicity. In this talk, I will review efforts to combine chemoradiation with inhibitors of the epidermal growth factor receptor as well as with agents that abrogate the G2 checkpoint and cause inhibition of homologous recombination repair. I will also illustrate how preclinical studies can motivate clinical trials through the example of an ongoing trial in locally advanced pancreatic cancer. 192 Jennifer A. Pietenpol, Vanderbilt-Ingram Cancer Center, Nashville, TN Treatment of patients with triple-negative breast cancer (TNBC) has been challenging due to the heterogeneity of the disease and the absence of well-defined “drivers” amenable to targeted therapies. Identification of molecular targets and predictive biomarkers is critical to improve outcomes for TNBC patients. Over the past several years, analysis of integrated genomic and clinical data sets has resulted in the classification of TNBC into subtypes. These subtypes now provide insight to potential targets and new strategies for this difficult-to-treat disease. The hope is that the further identification and validation of subtypespecific, gain- and loss-of-function drivers will lead to new strategies that align TNBC patients to effective targeted therapy and generate insights for further discovery efforts. AACR ANNUAL MEETING 2015 11_15AM_Sun_Layout 1 3/27/15 12:20 PM Page 193 Room 113, Pennsylvania Convention Center Novel Therapeutic Targets in Myeloma Kenneth C. Anderson, Dana-Farber Cancer Institute, Boston, MA This session will describe models of multiple myeloma (MM) in the bone marrow (BM) which have allowed for identification of novel targets and validation of targeted agents, which in turn have rapidly translated to clinical trials leading to nine FDA-approved treatments and a threefold prolongation of patient median survival. Novel immune therapies include: monoclonal antibodies; immunotoxins; cellular or peptide vaccines; as well as TLR agonists or checkpoint blockade. Next-generation proteasome inhibitors and deubiquitylating (DUB) can overcome resistance to first-generation bortezomib. Novel epigenetic therapies include isoform selective histone deacetylase inhibitors and bromodomain inhibitors. Finally, genomic studies are delineating MM heterogeneity; defining mechanisms of sensitivity or resistance to targeted therapies; identifying novel targets; and allowing for individualized treatments in MM. Terrace Ballroom I (400 Level), Pennsylvania Convention Center PI3K in Cancer: Divergent Roles of Isoforms, Modes of Activation, and Therapeutic Targeting Jean J. Zhao, Dana-Farber Cancer Institute and HMS, Boston, MA Phosphatidylinositol 3-kinases (PI3Ks) are critical coordinators of intracellular signaling in response to extracellular stimuli. Hyperactivation of PI3K signaling cascades is one of the most common events in human cancers. In this session, we discuss recent advances in our knowledge of the roles of distinct PI3K isoforms in normal and oncogenic signaling, the different ways in which PI3K can be upregulated, and the current state and future potential of targeting this pathway in cancer. Room 201, Pennsylvania Convention Center The Promise of Personalized Medicine Patricia M. LoRusso, Yale Cancer Center, New Haven, CT Room 114, Pennsylvania Convention Center Opportunities for Immunotherapy in Ovarian Cancer George Coukos, University Hospital of Lausanne, Épalinges, Switzerland Clinical data indicate that the immune system naturally recognizes epithelial ovarian cancers (EOC) and such immune response affects the outcome of patients with EOC; the presence of intraepithelial tumor-infiltrating lymphocytes correlates with improved progression-free and overall survival, as shown by studies conducted on over 1,700 patients. Tumor-infiltrating lymphocytes (TILs) isolated from ovarian cancers are oligoclonal and recognize and can lyse autologous tumor. TILs from ovarian cancer patients can recognize known tumor-associated antigens (TAAs). Important questions remain on the underlying biology that mediates the successful orchestration of antitumor immune response or the lack of T cell infiltration, as well as on the therapeutic opportunities to harness endogenous immunity and boost it with current immunotherapy approaches. We will attempt to elucidate the biology of immunogenic and non-immunogenic ovarian cancers, discuss data from emerging clinical immunotherapy studies, and propose important approaches to effectively mobilize antitumor immunity in EOC in the future. April 18-22, 2015 • Philadelphia, PA In the genome-enabled era, it is becoming obvious that a more personalized approach to cancer will be necessary if we are going to make an impact on the treatment of this disease. However, the clinical complexities of incorporating individualized molecular profiling into therapeutic interventions are significant. The challenges are multiple: defining the appropriate platform(s) for genomic characterization; harvesting relevant tumor tissue; serial sampling for determination of relevant molecular signature; drug effect and mechanisms of resistance; having the right drugs available; requiring agents from multiple different sponsors; having “clean” agents that are not multitargeted so as to maximize target inhibition and minimize nontarget toxicities; inability to combine necessary targeted agents due to overlap in toxicities, are but a few. Additionally, many tumors have multiple pathways that need simultaneous targeting, challenging such routine drug development concepts as relevant drug doses and schedules. Even if many of the above challenges are overcome, there remain challenges regarding optimization of trial design, especially for molecular subgroups of patients that may be very small. In this session, we will discuss these issues and how the clinical community is attempting to advance forward into a more personalized therapeutic approach to cancer treatment. 193 11_15AM_Sun_Layout 1 3/27/15 12:20 PM Page 194 MEET-THE-EXPERT SESSIONS Sunday, 7:00 a.m.-8:00 a.m. Room 103, Pennsylvania Convention Center Room 115, Pennsylvania Convention Center The PTEN Tumor Suppressor Tumor Dormancy and Recurrence Ramon E. Parsons, Icahn School of Medicine at Mount Sinai, New York, NY Lewis A. Chodosh, University of Pennsylvania, Philadelphia, PA PTEN, the phosphatase and tensin homolog on chromosome 10, is inactivated in a wide array of human cancers by a variety of different mechanisms that occur at the genetic, epigenetic, transcript, and protein levels. Understanding the mechanisms of inactivation of the gene and different potential combinations of such mechanisms in an individual tumor is important for gauging the extent of PTEN’s contribution to tumor growth. Inactivation of PTEN leads to increased levels of phosphatidylinositiol3,4,5-trisphostate inside the cell which activates multiple parallel signaling pathways including RAC, AKT, mTOR, BTK, and SGK3. Loss of PTEN function cooperates with PI3K class I isoforms to activate cell surface receptor signals, including insulin and EGF receptor family members, to alter cell metabolism, increase proliferation, and inhibit cell death. In addition, PTEN has tumor suppressor functions that are outside of the PI3K pathway. Reducing PI3K signals or restoring PTEN in tumors or the tumor microenvironment has potential therapeutic benefit. For many types of human cancer, residual tumor cells remain following treatment that are not detected by conventional clinical testing. These cells have the ability to survive in a presumed dormant state within tissues for up to 20 years, either as solitary cells or as micrometastases. Ultimately, residual cells re-emerge from this latent state and resume growth, leading to cancer recurrence. Despite the unrivaled clinical importance of these aspects of breast cancer progression, the mechanisms underlying them are largely unknown. Since dormant residual tumor cells constitute the reservoir from which recurrent cancers invariably arise, the lack of therapeutic approaches specifically targeted against these cells – as well as our lack of understanding about their biology – constitute major obstacles to the successful treatment of human cancers. As such, the development of targeted therapies designed to block pathways on which residual tumor cells depend for survival and growth would represent an attractive approach to preventing cancer recurrence. Room 118, Pennsylvania Convention Center Room 119, Pennsylvania Convention Center Targeting Essential Growth Drivers in NonSmall Cell Lung Cancer: A Lesson from ALK Unraveling Hormone Dependence in Cancer Hiroyuki Mano, University of Tokyo Graduate School of Medicine, Tokyo, Japan Targeting essential growth drivers that cancer cells are addicted to would be one of the most effective ways to treat cancer. Such hypothesis is clearly approved in the case for ALK fusions. Transgenic mice expressing EML4ALK in lung epithelial cells bear hundreds of lung tumors at birth, and such cancer nodules disappear upon the administration of an ALK inhibitor. Likewise, the first ALK inhibitor, crizotinib, obtained a remarkable response rate of ~60% in patients, and was approved at only 4 years after EML4-ALK discovery. Many “second-generation” ALK inhibitors are under clinical investigation, and one of them, alectinib, demonstrated a surprising response rate of 93.5%. Successful treatment by a single ALK inhibitor of non-lung tumors with other ALK fusions further validates an idea of “ALKoma,” a step toward a beyond-organ driver gene-based cancer classification. 194 Myles A. Brown, Dana-Farber Cancer Institute, Boston, MA Investigation of the steroid hormone dependence of breast and prostate cancers has served as the paradigm for the development of targeted therapies and has led to an understanding of the importance of an epigenetically defined cell of origin in determining response. It has also highlighted the importance of considering both genetic changes leading to clonal evolution and epigenetic changes resulting in altered differentiation as mechanisms underlying the development of acquired therapeutic resistance. This session will discuss recent studies aimed at elucidating the relative contributions of genetics and epigenetics in determining sensitivity to therapies targeting steroid receptor pathways and will provide potential new therapeutic strategies to overcome resistance. AACR ANNUAL MEETING 2015 11_15AM_Sun_Layout 1 3/27/15 12:20 PM Page 195 NCI/NIH-SPONSORED SESSION (not eligible for CME credit) Sunday, 7:00 a.m.-8:00 a.m. Room 105, Pennsylvania Convention Center NIH Grants Session: Changes in Review, Funding, and Funding Opportunities at the NCI Chairperson: Suresh Mohla, National Cancer Institute, Rockville, MD This session, held at every AACR annual meeting since the early 1990s, is primarily focused on familiarizing new applicants with the NIH grants submission, review, and funding processes. The session is predominantly focused on R01/R21 type grant applications since there are other NCI sessions focusing primarily on training, mentoring, and career development grant applications. Traditionally, this is a team effort between NCI and CSR. The one-hour session will include presentations from an SRO and an NCI Program Director, after which there will be an opportunity for questions. The session has been very popular with new, junior, and senior investigators because the speakers present new policies, procedures, and funding opportunities that are available to applicants. The major theme of this session is how to be proactive in preparing grant applications, and how to interact with the CSR and NCI staff before and after the applications have been reviewed. A variety of topics are discussed including how applicants can self-refer their applications, and issues related to “grantsmanship,” such as the common mistakes made in research applications and how to avoid them. It is a great opportunity for applicants to meet with NCI Program Staff, and with CSR and NCI Scientific Review Officers. The NCI and CSR staff will be available to meet either immediately after the session or in the NIH Resource Room for the duration of the meeting. Overall, this has been a successful forum to provide an overview of NCI paylines, plans and programs, funding opportunities, changes in grant submissions process, and other significant changes in review at CSR and NCI, and the AACR has enthusiastically endorsed this session since the very early 1990s. Speakers: Angela Y. Ng, Center for Scientific Review, National Institutes of Health, Bethesda, MD Ronald L. Johnson, National Cancer Institute, Rockville, MD Suresh Mohla, National Cancer Institute, Rockville, MD NCI Resource Room The NCI Grants Resource Room, located in Room 102 of the Philadelphia Convention Center, provides information and handouts related to new research initiatives and information on the grant application process, including Program and Review staff contacts. Program and Review staff of the NCI as well as Review staff from CSR will be available at the Resource Room for discussions and consultation throughout the meeting. A list with details of specific NCI and CSR staff availability will be posted in the room. Conferences can be scheduled to discuss individual grant/review questions. Interested members of the scientific community are encouraged to meet with Program or Review staff to clarify specific issues or other items of interest. New investigators are especially encouraged to meet with Program staff handling grant portfolios in their area of scientific interest. The Resource Room will be open from 9:00 a.m. to 5:00 p.m. Sunday through Tuesday, and from 9:00 a.m. until noon on Wednesday, April 18-22, 2015 • Philadelphia, PA 195 11_15AM_Sun_Layout 1 3/27/15 12:20 PM Page 196 OPENING CEREMONY (not eligible for CME credit) Sunday, 8:15 a.m.-9:30 a.m. Join us on Sunday for the Annual Meeting Opening Ceremony, a yearly tradition marking the start of four days filled with outstanding and innovative science. AACR CEO Margaret Foti, PhD, MD (hc), will address attendees and discuss the immense progress the AACR has made over the past year. AACR President Carlos L. Arteaga, MD, FAACR, will highlight the dramatic advances in cancer research and today’s challenges to the cancer field.

The AACR Team Science Award recognizes an outstanding interdisciplinary research team for its innovative and meritorious science that has advanced or likely will advance our fundamental knowledge of cancer or a team that has applied existing knowledge to advance the detection, diagnosis, prevention, or treatment of cancer. The AACR recognizes the Designing AR Inhibitors Team for their collective efforts in discovering and developing the novel antiandrogen drugs enzalutamide and ARN-509 for the treatment of castration-resistant prostate cancer. This multidisciplinary group, comprised of cancer biologists, chemists, and clinical scientists, exemplifies the power of team work and its ability to make a difference to change the way we treat major diseases. The team used a combination of laboratory models and clinical samples to discover that restoration of signaling through overexpression of the androgen receptor (AR) is responsible for acquired resistance to androgen treatment. They then used this information to discover and optimize novel small-molecule inhibitors of the androgen receptor that retain activity in AR-overexpressing models of androgen-resistant prostate cancer. The team also showed that these compounds work by impairing nuclear translocation of the AR and disrupting its binding to promoter and enhancer regions of AR target genes. The team then went on to carry out the first human trial of the drug emerging from their preclinical work, initially known as MD3100 and then as enzalutamide, which showed substantial clinical activity. Subsequent clinical trials resulted in FDA approval in 2012. The team has also discovered and progressed to clinical trial a further more potent antiandrogen (ARN-509). In addition, they have provided important evidence supporting dual blockade of AR and PI3 kinase to overcome reciprocal negative feedback signaling in castration-resistant prostate cancer and again progressed this to the clinic. The outstanding scientific, translational, and clinical accomplishments of the team and their commitment to a multidisciplinary team approach is clearly evidenced by their innovative and meritorious work that has resulted in major clinical impact and perfectly embodies the spirit of the AACR Team Science Award. April 18-22, 2015 • Philadelphia, PA 199 11_15AM_Sun_Layout 1 3/27/15 12:20 PM Page 200 OPENING CEREMONY (not eligible for CME credit) Sunday, 8:15 a.m.-9:30 a.m. Hall A (200 Level), Pennsylvania Convention Center Twelfth Annual AACR Award for Lifetime Achievement in Cancer Research Mario R. Capecchi, PhD, FAACR University of Utah, Salt Lake City, UT The American Association for Cancer Research Award for Lifetime Achievement in Cancer Research was first established in 2004 to honor individuals who have made significant fundamental contributions to cancer research, either through a single scientific discovery or a collective body of work. These contributions, whether they have been in research, leadership, or mentorship, must have had a lasting impact on the cancer field and must have demonstrated a lifetime commitment to progress against cancer. The AACR honors Dr. Mario R. Capecchi for his tremendous scientific contributions, which have had a profound impact on the understanding of cancer. Dr. Capecchi’s groundbreaking work in the development of gene targeting technology in the mouse has led to a revolution in our ability to study the function of cancer genes, as well as the mechanisms of cancer development. He clearly embodies the tradition of outstanding scientific accomplishments that are represented by this Award and its previous recipients. After initial training in physics and chemistry, Dr. Capecchi was seduced by the emerging discipline of molecular biology. As a graduate student with Jim Watson at Harvard University, he synthesized bacteriophage proteins in cell-free extracts and worked out some of the basic mechanisms controlling protein synthesis. Dr. Capecchi then joined the faculty of Harvard Medical School, but after four years he decided to move to the University of Utah to pursue new long-term avenues of research in mammalian molecular biology that ultimately revolutionized our approach to understanding gene function. The challenge Dr. Capecchi chose to pursue was how to manipulate the mammalian genome to understand gene function. His first proposal, to inject DNA into nuclei, was turned down by the NIH as “not worthy of pursuit.” Undaunted by rejection, he persisted and four years later a second proposal was accepted with the belated apology from the study section: “We are glad you did not follow our advice.” Introducing DNA into the mammalian genome was just the first step in a series of discoveries leading to the development of procedures to target, disable, and study individual mammalian genes using homologous recombination. Key to the success of the approach was Dr. Capecchi’s remarkable persistence and continued refinement of technology to the point where targeted mutation of mammalian genes became routine. The demonstration that this approach allows introduction of mutations into chromosomal DNA of embryoderived mouse stem (ES) cells, and transmission of the mutations through the germline 200 AACR ANNUAL MEETING 2015 11_15AM_Sun_Layout 1 3/27/15 12:20 PM Page 201 to progeny, was recognized by the award of the Nobel Prize in Medicine to Dr. Capecchi together with Drs. Oliver Smithies and Martin Evans. It is hard to overstate the impact of this advance in biology and medicine. Many tens of thousands of knockout mice and their variants have been created leading to numerous advances in understanding and modeling of many human diseases. In cancer research, targeted mutation of oncogenes, tumor suppressor genes, and modifier genes fundamentally changed the direction of the field, permitting direct analysis of the molecular events leading to tumor initiation and progression. New models that better reflect the biology of human cancer have been generated and used to develop novel therapies. In his most recent work, Dr. Capecchi focused on chromosomal translocations that cause sarcomas by usurping normal developmental processes involved in muscle formation. Cancer researchers throughout the world rapidly adopted Dr. Capecchi’s technology. It is now possible to identify the cell of origin of many cancers and to investigate the actual mechanisms that generate cancer mutations – in some cases a pathophysiological version of the mechanisms Dr. Capecchi exploited to achieve gene targeting. Investigators can now approach the diversity of cancer in mouse models and the heterogeneity of tumor cells that makes them so difficult to eradicate. Through a lifetime dedicated to scientific discovery, Dr. Capecchi has left an indelible mark on cancer research and he has improved the lives of countless cancer patients. He has also served as an inspiring mentor to his students, fellows, and colleagues and as a role model for all young investigators who dare to think differently. April 18-22, 2015 • Philadelphia, PA 201 11_15AM_Sun_Layout 1 3/27/15 12:20 PM Page 202 OPENING CEREMONY (not eligible for CME credit) Sunday, 8:15 a.m.-9:30 a.m. Hall A (200 Level), Pennsylvania Convention Center 2015 AACR Distinguished Public Service Award Siddhartha Mukherjee, MD, PhD Pulitzer Prize-winning author of “The Emperor of all Maladies: A Biography of Cancer” and assistant professor in the Department of Medicine at Columbia University The AACR is honoring Dr. Siddhartha Mukherjee with the 2015 Distinguished Public Service Award in recognition of his outstanding work educating the public about cancer and cancer research through his Pulitzer Prize-winning book, The Emperor of All Maladies: A Biography of Cancer. Dr. Mukherjee wrote the book, which was published in 2010, because he felt that his experiences as an oncology fellow at the Dana-Farber Cancer Institute and Massachusetts General Hospital in Boston during the mid-2000s were part of a much larger battle against cancer. Through his writing, he set out to paint a picture of the history of cancer and to answer the tough questions from his patients that he had been unable to answer about the origins of cancer, how treatment has evolved, and how we can develop new and more effective treatments. The Emperor of All Maladies: A Biography of Cancer provides deep insight into the amazing progress that has been made against cancer over the years thanks to research, and accomplishes Dr. Mukherjee’s goal of better educating the public about cancer and cancer research. By focusing on the pioneering physicians and researchers who developed surgical procedures and conducted experiments with chemotherapy, as well as the trailblazing scientists who revealed the mechanisms of cancer initiation and progression, Dr. Mukherjee covers the first documented appearances of cancer four thousand years ago through to the emergence of precision medicine. Intertwined with the stories of research and medical advances are those of activists who raised public awareness of cancer and of patients who experienced the highs and lows of treatment. These stories bring a level of humanity to the book that resonates deeply with the public. In 2011, The Emperor of All Maladies: A Biography of Cancer won the Pulitzer Prize for general nonfiction. A six-hour documentary based on the book, Cancer: The Emperor of All Maladies, aired on Public Broadcasting Service member stations across the United States, on March 30, 31, and April 1. The American Association for Cancer Research and Stand Up To Cancer are proud supporters of the documentary, executive produced by Ken Burns and directed by Barak Goodman, which has created a national dialogue about cancer and the vital importance of cancer research. The documentary series is a collaboration between Florentine Films, Laura Ziskin Pictures, and WETA, in association with Ark Media. Dr. Mukherjee is an assistant professor in the Department of Medicine at Columbia University in New York, where he studies the pathogenesis of acute myeloid leukemia and myelodysplastic syndromes. He received his doctorate in immunology from the University of Oxford, United Kingdom and his medical degree from Harvard Medical School. He lives in New York with his wife and daughters. 202 AACR ANNUAL MEETING 2015 11_15AM_Sun_Layout 1 3/27/15 12:20 PM Page 203 Photo by Viva Sarah Press/ISRAEL21c Hall A (200 Level), Pennsylvania Convention Center 2015 AACR Award for Distinguished Public Service and Global Impact in Cancer Advocacy Miri Ziv Director General, Israel Cancer Association, Givatayim, Israel Miri Ziv, Director General of the Israel Cancer Association, is being honored with the 2015 AACR Award for Distinguished Public Service and Global Impact in Cancer Advocacy for her sustained spectacular contributions to the cancer field and her lifelong passionate commitment to the global conquest of cancer. Through her remarkable work as the Director General of the Israel Cancer Association, the leading not-for-profit cancer organization in Israel, she has served the cancer field with distinction. Her advocacy in the area of breast cancer has been especially significant.

She has initiated many programs to raise awareness about cancer and has been a tireless advocate for the cause of cancer control, providing guidance in Israel and to numerous international organizations on issues relevant to public awareness about cancer, cancer prevention, and services to cancer survivors. She has been the driving force as an advocate behind initiatives such as the National Mammography Screening Program in Israel, Skin Cancer Awareness Month, and many other important public education programs. Ms. Ziv is truly a global cancer ambassador and a precious asset to the cancer field. Because of all of her past stellar accomplishments and the global impact of her current contributions to cancer advocacy, cancer control, and cancer research, she is highly deserving of this recognition by the AACR. Ms. Ziv earned a master’s degree in medical sociology, with honors, at Tel Aviv University, and completed the study requirements for the PhD program there. She taught medical sociology at Tel Aviv University for about a decade prior to assuming her position at the Israel Cancer Association. In Israel, Ms. Ziv has served for more than 20 years as a member of The Israel National Health Committee (appointed by the Minister of Health) and as Coordinator of the Israel National Council of Oncology. She is a member of the National Council for Women’s Health, the National Council of Health Promotion (both of which are by April 18-22, 2015 • Philadelphia, PA appointment of the Director General of the Ministry of Health), and the Executive Board of the Israel Health Consumers Coalition. Internationally, Ms. Ziv has served since 1995 as Israel’s representative to the European Breast Cancer Coalition Europa Donna, and on its Executive Board from 1995 to 2000. She is a member of the Executive Board of the Senologic International Society (the World Society of Breast Diseases) and is a Senior Research Fellow of the International Prevention Research Institute. She has also served on the Executive Board of the European Cancer Leagues and on the Executive Board of the Union for International Cancer Control. She was elected as a Global Cancer Ambassador by the American Cancer Society, and she was a member of the Israeli delegation to the U.N. General Assembly Meeting on Non-communicable Diseases in September 2011. In 2015, she was appointed as an ESMO Faculty Member for Cancer Prevention in recognition of her enormous expertise in this area. In addition, Ms. Ziv has participated in and lectured at conferences in Israel and around the world, such as the Global Summit Consensus Conference on International Breast Health in Washington, DC; a meeting of the Senologic International Society in Paris; the Eighth International Congress of Diagnosis and Treatment of Breast Cancer in Warsaw; the Middle East Cancer Control Leadership Forum in Ankara, Turkey; and the Second Breast Cancer in Young Women Conference in Dublin, Ireland. Ms. Ziv has received numerous awards including the “Best CEO in Israel,” the Nurit Kadatzaki-Roz Award for her achievements against cancer, and the Israeli Society for Clinical Oncology & Radiation Therapy Gold Medal for her contributions to its work, among other honors. Her commitment to the cause of fighting cancer began many years ago. It was deepened in 1992 when her own son, Oren, died of melanoma at the age of 21, and it was strengthened further when her brother also lost his life to cancer 14 years ago. Ms. Ziv and her husband, Joseph, a retired Israeli Defense Forces helicopter pilot who works in environmental services, live in the town of Yavne, south of Tel Aviv. 203 11_15AM_Sun_Layout 1 3/27/15 12:20 PM Page 204 OPENING CEREMONY (not eligible for CME credit) Sunday, 8:15 a.m.-9:30 a.m. Hall A (200 Level), Pennsylvania Convention Center Fellows of the AACR Academy Class of 2015 The AACR Academy serves to recognize and honor distinguished scientists whose major scientific contributions have propelled significant innovation and progress against cancer.

Casey, Jr. United States Senator from Pennsylvania Senator Bob Casey has represented the Commonwealth of Pennsylvania in the United States Senate since January 2007. In his eight years in the Senate, Bob Casey has been a steadfast leader in support of funding for the National Institutes of Health (NIH). He has consistently demonstrated, through his work as a member of the Senate Health, Education, Labor and Pensions Committee, an unwavering commitment to advancing science, protecting children, and improving public health. Perhaps most notably, Senator Casey reaches across the political aisle and works with his Republican colleague, Senator Richard Burr, to lead a Dear Colleague letter to Senate leadership in support of NIH funding each year. This letter is critical to raising awareness among his colleagues that NIH funding should be a national priority. Last year the letter garnered the support of almost 60 senators. In addition to his leadership on NIH funding, Senator Casey was the lead Senate sponsor of the Creating Hope Act, which became law in 2012 and established the Priority Review Voucher program at the U.S. Food and Drug Administration (FDA) to include treatments for pediatric rare diseases, such as childhood cancers. He also has demonstrated support for AACR-led initiatives such as National Cancer Research Month by serving as an original cosponsor of a special resolution in Congress honoring the event. Senator Casey and his wife of 30 years, Terese, live in Scranton, PA, and have four daughters. Senator Casey is the eldest son of the late Governor Robert P. Casey. Throughout his career in public service, which has spanned almost 20 years, Senator Bob Casey has been guided by the legacy of his father and the principle that “All public service is a trust, given in faith and accepted in honor.” 208 AACR ANNUAL MEETING 2015 11_15AM_Sun_Layout 1 3/27/15 12:20 PM Page 209 Hall A (200 Level), Pennsylvania Convention Center 2015 AACR Distinguished Public Service Award Richard Pazdur, MD Director of the Office of Hematology and Oncology Products U.S. Food and Drug Administration, Silver Spring, MD The AACR is honoring Dr. Richard Pazdur with a Public Service Award in recognition of his steadfast leadership as Director of the U.S. Food and Drug Administration’s (FDA) Office of Hematology and Oncology Products and of his extraordinary dedication to improving cancer treatment through the approval of safe and effective drugs for cancer patients. Throughout his stellar career, Dr. Pazdur has made outstanding contributions to the fight against cancer, initially through his highly regarded work as a physician and researcher and now through his extraordinary dedication to improving cancer treatment via the approval of safe and effective drugs for cancer patients at the FDA. Dr. Pazdur, who is sometimes referred to as the “Cancer Drug Czar” by the media, has led the FDA Office of Hematology and Oncology Products (OHOP) since 2005. During this time, he has worked tirelessly to speed the availability of therapies for cancer patients, especially when the drugs are the first available treatment or have advantages over existing therapies. On an annual basis, approximately 30 percent of all new drugs approved by the FDA are oncology products, and under his leadership, the Office has approved many novel, innovative treatments for patients, such as the recent approvals of immune-checkpoint inhibitors, immune modulators, and many of the targeted therapies that have not only extended patient lives, but have also greatly improved the quality of their lives. For these reasons, Dr. Pazdur was recently named one of “The World’s 50 Greatest Leaders” by Fortune magazine. Dr. Pazdur has worked for years to build collaborative partnerships with academia, industry, fellow government agencies, scientific societies, and patient advocacy organizations to improve both the pace and the quality of new cancer drugs reaching patients. He has embraced regulatory science to inform and improve the way in which new cancer medicines can be evaluated for their safety and efficacy. He is also a thought leader and has effectively employed a variety of regulatory tools such as master clinical trial protocols, expedited approval pathways, including the agency’s new breakthrough therapy designation and clinical trial enrichment strategies for approving targeted therapies in oncology. A native of the Chicago area, he obtained his Doctor of Medicine (MD) from Loyola Stritch School of Medicine. He served as an oncologist, researcher, and teacher at Wayne State University before becoming a Professor of Medicine and Assistant Vice President for Academic Affairs at the M.D. Anderson Cancer Center at the University of Texas. He joined the FDA as the Director of the Division of Oncology Drug Products in 1999 and was named Director of the Office of Hematology and Oncology Drug Products in April 2005. He resides in Bethesda, MD, with his wife, Mary, and is a fitness enthusiast.

Dalton, M2Gen, Tampa, FL We are making unprecedented progress in cancer research that is changing the way we prevent, diagnose, and treat cancers in this country, thanks in no small part to federal investments in cancer research at the National Cancer Institute (NCI) and the National Institutes of Health (NIH). But despite the tremendous promise of cancer research, our nation’s premier sources of funding—the NIH and NCI— are amidst a serious funding crisis as a result of cuts in domestic spending, including sequestration, and years of budgets that have not kept pace with inflation. Through the actions of our Science Policy and Government Affairs Committee, the AACR is raising awareness for how investments in cancer and medical research will save lives, improve public health, and grow the economy in this country. The AACR also works closely with other organizations across all areas of medical science to advocate for increased research funding and support. By educating Congress about the importance of federal investments in biomedical research and how those investments provide a significant health and economic benefit to the country, the AACR is working tirelessly to ensure that our nation’s policymakers prioritize the growth of the NIH and NCI budgets at a predictable, robust pace. The AACR also engages with federal agencies to promote the development and implementation of sound, evidence-based policies to support, cancer survivors, scientists, and the broader medical research ecosystem. This special session will give you an overview of the AACR’s activities in Washington, D.C., to support NIH funding and lead on other policy issues, such as tobacco and regulatory science. It also will arm cancer researchers with the knowledge and tools needed to be effective advocates, especially in the current, complex political and fiscal environments that exist in Washington, D.C. The session will conclude with a roundtable “Ask Me Anything” discussion with leaders of the AACR Science Policy and Government Affairs Committee. Speakers: William S. Dalton, M2Gen, Tampa, FL Jon G.

Macleod, University of Chicago Ben May Institute for Cancer Research, Chicago, IL Determining the role of the self-degradative cellular process known as macro-autophagy in cancer has been complicated by the realization that autophagy can be both tumorpromoting and tumor-suppressive depending on tissue type, driving oncogene, and stage of progression. This session addresses some of the key questions and controversies pertaining to the role of autophagy in cancer etiology and treatment including the function of autophagy in the tumor microenvironment, the relative importance of mitophagy relative to the process of autophagy as a whole, the significance of key oncogenic signaling pathways in modulating autophagy, and importantly the utility of chloroquine and other lysosomotropic drugs in cancer therapy. This session brings four experts in the field together to present new data from their laboratories on these topics and to discuss the ramifications of their work for unanswered questions in the field. 1:00 p.m. Introduction 1:10 p.m. Contrasting consequences of autophagy deficiency and mitophagy deficiency in cancer [SY01-01]* Kay F. Macleod, University of Chicago Ben May Institute for Cancer Research, Chicago, IL Chairperson: Tim E. Byers, University of Colorado Cancer Center, Aurora, CO The major chronic diseases (cancer, type 2 diabetes, and cardiovascular disease) share many behavioral risk factors, including tobacco, diet, obesity, and physical inactivity. In addition, many mediating biological processes seem to have similar effects on disease risk across these conditions, including various hormonal factors and chronic inflammation. In some instances, the mechanisms for how behavioral factors affect risk are known, but in many instances those mechanisms are unknown. The purpose of this session is to systematically examine the similarities and differences in how behavioral factors are related to risk of cancer, type 2 diabetes, and cardiovascular disease within the same cohorts in order to better define the limits of our current understanding of common mechanisms that might affect risk of multiple chronic diseases. 1:00 p.m. Introduction 1:10 p.m. Cancer, type 2 diabetes, and cardiovascular diseases: Different stops on the same line?

However, there are currently no effective therapies for Ras-driven tumors. This session will focus on how basic mechanistic and preclinical studies in a variety of model systems have been used to develop new small molecule inhibitors, identify new targets and novel drug combinations, and can guide mechanism-based clinical trials. Key issues for using the full potential of the iPS cell technology for disease research are creating molecular and biological criteria that allow characterization of different cell states. This symposium will discuss recent approaches aimed at establishing molecular criteria that define the pluripotent and differentiated state of human cells as well as establishing stringent criteria that can be used for quality control of iPS cells. In addition, efficient gene editing approaches in human pluripotent cells that are needed for creating disease-relevant phenotypes in the culture dish will be discussed. 1:00 p.m. Introduction 1:10 p.m. Small molecule targeting K-Ras G12C Kevan M.

Campbell, Wellcome Trust Sanger Institute, Cambridge, United Kingdom As immune therapies for cancer continue to advance with promising results, molecular imaging strategies to monitor immune cell subsets are also evolving. In order to truly maximize benefit of a given individual’s immunotherapy, one has to be able to answer many important questions. These include: 1) Visualization of the location(s), numbers, and viability of specific immune cell subsets, 2) Visualization of the interaction of the immune cell with tumor cells, 3) Visualization of specific immune cell and tumor cell targets (e.g., checkpoint inhibitors), and 4)Visualization of the efficacy of tumor volume reduction. Multiple new molecular imaging probes for various imaging modalities (e.g., positron emission tomography) are being translated for clinical use and may help to fully optimize existing and evolving immunotherapies. Investigators developing novel immunotherapies working closely with the molecular imaging community should lead to improved cancer management through advances in both immunotherapy and molecular imaging probe development. The Pan-Cancer analysis of Whole Genomes (PCAWG) project of the International Cancer Genome Consortium (ICGC) and The Cancer Genome Atlas (TCGA) is coordinating analysis of more than 2,000 whole cancer genomes. Each genome is characterized through a suite of centralized algorithms, including alignment to the reference genome, standardized quality assessment, and calling of all classes of somatic mutation. Scientists participating in the research projects of PCAWG are addressing a series of fundamental questions about cancer biology and evolution based on these data, a sample of which will be presented at this session. Key areas of study include: 1) Discovery of driver mutations outside of the protein-coding regions of the genome; 2) Integrating mutational signatures across tumor types and mutation categories; 3) Characterizing subclonal structures and patterns of genome evolution across cancers; 4) Investigating relationships between germline and somatic mutations; 5) Investigating biological pathways targeted by driver mutations. 1:00 p.m. Introduction 1:10 p.m. Non-immunogenic PET reporter imaging of HSC transplants and T cell immunotherapies [SY05-01]* Owen N.

Genomic Investigations in Childhood Cancers Chairperson: Diether Lambrechts, Catholic University of Leuven, Leuven, Belgium Antiangiogenic therapies have been proven to slow metastatic disease progression in patients with cancer. Although they have changed clinical practice, some patients do not respond or gradually develop resistance, resulting in rather modest gains in terms of overall survival. A major challenge is to develop robust biomarkers that can guide selection of those patients for whom antiangiogenic therapy is most beneficial. In this session, we will discuss recent progress in identifying such markers, including potential circulating plasma markers, as well as novel (epi)genetic and imaging biomarkers. Finally, we will also focus on novel insights underlying resistance to antiangiogenesis, and how these may offer new strategies and opportunities to overcome resistance to antiangiogenic therapy. 1:00 p.m. Personalized antiangiogenic therapy: Insights, strategies, and opportunities Lee M.

They provide new clues to decipher the molecular mechanisms of tumor development and new biomarkers that can be tested in a clinical setting. The long thought inter- and intratumor heterogeneity of neuroblastoma, brain tumors, and sarcoma can now be documented on precise genetic bases. The contributions of divergent subclones in the dynamics and plasticity of the tumor ecosystem can be addressed. Germline genetic analyses have also considerably increased our knowledge of the individual susceptibility to develop these cancers. The challenge ahead is now to use this new information to improve the management of patients and to propose and implement new strategies for diagnosis, follow up, and treatment. 1:00 p.m. Translating genomic landscapes into better treatments: Opportunities and challenges in neuroblastoma John M.

Finn, University of Pittsburgh School of Medicine, Pittsburgh, PA Most immune-based approaches to dealing with the cancer epidemic, including vaccines, have focused on people who have already developed cancer. Vaccines against cancer causing viruses have had great successes in preventing cancer by targeting viral antigens. Non-viral cancers also express antigens that trigger immune responses and testing vaccines against these antigens to prevent cancer occurrence or progression has become possible. This session will review ongoing efforts to prevent both viral and non-viral cancers by vaccinating individuals at risk. A combination of animal and human studies will be presented with special emphases on targeting antigens present on premalignant lesions. 1:00 p.m. Vaccines targeting antigens expressed in preinvasive lesions Mary L.

Katzenellenbogen, University of Illinois at Urbana-Champaign, Urbana, IL Chairperson: Adele C. Green, Queensland Institute of Medical Research, Brisbane, Australia Cancer is characterized by marked changes in the patterns of gene expression arising from alterations in signaling pathways and changes in transcription factor binding and activity. This symposium will cover various approaches taken to understand in what ways estrogen receptor (ER) activity and ER itself are altered in breast cancers. It will also explore how a better understanding of these changes might lead to improved endocrine therapy agents targeting ER or other components of its signaling pathway. The presentations will cover how the genomic activity of ER is altered in breast cancers, how ER mutations in recurrent disease can defeat current endocrine therapies, how the transcriptional activity of ER might be regulated by targeting coregulators, and how positron emission tomographic imaging of ER levels and ER function might improve the selection of patients most likely to benefit from endocrine therapies. This session pulls together a diversity of recent evidence about UV radiation as the main causal agent for melanoma. Starting with an overview of the evidence from human populations, we then consider the specific mechanisms involved in melanoma’s pathogenesis. We show how mouse models and next-generation sequencing are being used to investigate UV-driven melanomagenesis. We next look at how UV affects the balance between antitumor immunity and protumorigenic inflammatory responses in the skin microenvironment, focusing on the neutrophil’s ability to promote melanoma-endothelial cell interactions. Finally we discuss the interrelationships between the skin, melanin synthetic pathways, and UV radiation that underlie melanoma risk, with insights from genetically defined models and measures ranging from the molecular to the behavioral. 1:00 p.m. Understanding the genomic properties of estrogen receptor activity in breast cancer Jason Carroll, Cancer Research UK Cambridge Research Institute, Cambridge, United Kingdom 1:20 p.m. Discussion 1:25 p.m. Biologic and clinical significance of estrogen receptor mutations in cancer Sarat Chandarlapaty, Memorial Sloan Kettering Cancer Center, New York, NY 1:45 p.m. Discussion 1:50 p.m. Mechanisms and therapy potential for transcriptional coactivators David M.

Prowell, U.S. Food and Drug Administration, Silver Spring, MD, and Johns Hopkins Kimmel Cancer Center, Baltimore, MD Clinical evidence supports the use of neoadjuvant treatment in high-risk early-stage breast cancer. The U.S. Food and Drug Administration (FDA) recently finalized guidance on "Pathological Complete Response in Neoadjuvant Treatment of High-Risk Early-Stage Breast Cancer: Use as an Endpoint to Support Accelerated Approval," and further has granted accelerated approval to pertuzumab for neoadjuvant treatment of early-stage breast cancer. This session will explore the potential for drug development and approval in the neoadjuvant setting in other solid tumors, namely melanoma and bladder cancer. Speakers will discuss the scientific, clinical, and regulatory considerations for use of the neoadjuvant pathway in drug development, as well as lessons that can be learned from the neoadjuvant breast cancer setting that may be applicable to other solid tumors. A panel discussion moderated by Tatiana Prowell, U.S. Food and Drug Administration, and Marc Theoret, Food and Drug Administration, and audience Q and A will follow the presentations.

Hutter, National Human Genome Research Institute, Rockville, MD Recognizing the potential of clinical next-generation sequencing (NGS) for the realization of precision cancer care, the National Cancer Institute (NCI) has expanded its efforts to investigate how the discovery and analysis of genomic alterations can be translated into more effective diagnosis, treatment, and prevention of cancer. To this end, NCI participates in the Clinical Sequencing Exploratory Research (CSER) program, co-funded with the National Human Genome Research Institute (NHGRI), which aims to leverage these institutes’ experience in genomic sequencing and analysis to conduct a robust investigation of the use these methods in clinical practice. The goal of CSER is to guide the development and dissemination of best practices for the integration of clinical sequencing into clinical care, including how clinical sequencing results will be communicated to physicians and patients. The collaborative and cooperative nature of the CSER, including the formation of a tumor sequencing working group, facilitates the development and standardization of best practices and common approaches to clinical translation of cancer sequencing. One critical issue that CSER seeks to address is how to determine whether a particular genetic variant is “actionable.” This NCI-sponsored panel session will focus on how tumor exome sequencing projects within CSER assess and report the actionability of variants identified through clinical somatic sequencing. The session will begin with an overview of CSER, which currently comprises nine cooperative U01 grants, nine R01/R21 grants examining return of results, and NHGRI’s intramural ClinSeq program. Four U01 grants focus on cancer phenotypes: • Baylor College of Medicine (BASIC3 study) – Tumor and germline sequencing of newly diagnosed children with high-risk central nervous system (CNS) and non-CNS solid tumors. • University of Michigan (MI-ONCOSEQ study) – Tumor and germline sequencing of patients with metastatic and refractory cancers, including sarcomas and rare tumors. • Dana-Farber Cancer Institute (CanSeq study) – Tumor and germline sequencing of patients with metastatic or refractory lung and colorectal cancer. • University of Washington (NEXT Medicine study) – Germline sequencing of patients with colorectal cancer or polyposis. In the body of the session, the three CSER projects conducting tumor exome sequencing (BASIC3, MI-ONCOSEQ, CanSeq) will each briefly describe their clinical context, project goals, study design, and early study experience with clinical sequencing. Each group will then describe the pipeline utilized at their institution for the annotation and evaluation of tumor variants, including 1) their working definition of “actionable” (e.g., informative for choice of drug or potential entry into clinical trial), 2) the evidence considered to make that assessment (e.g., institutional databases, published literature), and 3) the process by which a final determination of actionability is made (e.g., consensus meetings or tumor board/panel). The session will close with a panel discussion, in which representatives from each project will answer audience questions. The panelists will also highlight key lessons learned in their development of clinical NGS programs; discuss connections to other NIH initiatives including the Clinical Genome Resource (ClinGen); and outline current opportunities and challenges to translating genomic medicine into routine clinical cancer care.

Blumenthal, U.S. Food and Drug Administration, Silver Spring, MD Advances in biomarker identification have revolutionized oncology drug development and patient care by enabling precision targeting of tumor mutations usually accompanied by increased efficacy and lower adverse effects. In conjunction, the regulatory requirements for approval of targeted cancer drugs have also changed, most notably by requiring the development and approval of a companion diagnostic to identify the appropriate patient subpopulation who will benefit from the therapy. Several kinase inhibitors targeting specific mutations in genes such as BRAF and EGFR have been approved, demonstrating the success of such approaches. However, new scientific and regulatory challenges have arisen, specifically with regards to differential tumor response to targeted therapies based on the specific genomic alteration or tissue of origin, alternative pathway selection within the tumor resulting in resistance to targeted therapies, and the development of new technologies enabling multiple biomarker identification, confounding the one-drug/one-test paradigm. This session will highlight the evolution of the scientific and regulatory underpinnings of approved kinase inhibitors, using EGFR and BRAF inhibitor development as case studies, as well as future considerations for targeted drug development. The session will address issues such as: • Understanding mechanisms of acquired resistance to kinase inhibitors • Combining multiple targeted therapeutic agents to combat resistance • Use of novel technologies such as circulating tumor DNA to identify and predict development of resistance • Development of companion diagnostics in the era of multiplex testing and massively parallel sequencing A panel discussion moderated by Gideon M. Blumenthal, U.S. Food and Drug Administration, and audience Q and A will follow the presentations. Speakers: Gideon M. Blumental, U.S. Food and Drug Administration, Silver Spring, MD Pasi A.

This investigator-driven, pioneering frontier research funded is now starting to bear fruit. Horizon 2020 (H2020), the new European Union framework program for research and innovation runs from 2014-2020. With a budget of €77 billion, Horizon 2020 is a key component of Europe’s strategy to create economic growth and to reinforce its global competitiveness. The European Research Council (ERC) is part of H2020’s first pillar of “Excellent Science” and has a budget of over €13 billion, an approximate 75% increase compared to the previous framework program. This substantial budget increase will allow the ERC to continue its mission – finding and funding the very best researchers with the most creative ideas. Through highly competitive selections for attractive grants, the ERC promotes junior and established researchers to pursue their work in Europe in any field of research and regardless of their nationality. Encouraging international scientific cooperation, the ERC supports top researchers from anywhere in the world, including the USA. Since 2007, more than 4,000 projects have been selected for funding from more than 43,000 applications, including several Nobel Prize winners. The workshop will explain the ERC’s funding schemes as well as provide answers to practical questions such as: • How does the ERC support research careers? • What are their main features? • What are the main changes for the ERC with respect to the new Horizon 2020 framework? • What are the selection criteria and how long is the selection process? • How does the application process work? • How many researchers are funded each year? • What are the chances of success?

Allison, PhD, FAACR The University of Texas MD Anderson Cancer Center, Houston, TX The Pezcoller Foundation-AACR International Award was established in 1997 to recognize a scientist who has made a major scientific discovery in basic cancer research, or who has made significant contributions to translational cancer research; who continues to be active in cancer research, and has a record of recent and noteworthy publications; and whose ongoing work holds promise for continued substantive contributions to progress in the field of cancer. This award honors James P. Allison, PhD, for his seminal discoveries that established new paradigms in basic cancer immunology and led to the development of novel cancer therapeutics. Specifically, he is recognized for his identification of CTLA-4 as an inhibitory receptor on T cells that serves as a checkpoint to ensure proper control of immune responses. He subsequently developed and tested the hypothesis that blockade of CTLA-4 would enhance antitumor T cell responses by releasing CTLA-4 suppression. The success of these studies opened the field of immune checkpoint blockade in human cancer therapy. Dr. Allison’s findings have had a profound impact on patients and revolutionized the way we think about cancer treatment. Throughout his career, Dr. Allison has contributed significantly to the field of immunology. Early in his career, his laboratory provided several important insights into the basic mechanisms involved in T cell activation, T cell receptor structure, and antigen recognition. He also investigated other receptors that participated in regulation of T cell activation or inhibition; for example, the CD28 and CTLA-4 pair of T cell receptors was found to regulate dichotomous T cell responses when linked to their common binding protein, B7-1,2, on antigen presenting cells. Dr. Allison demonstrated that CD28 engagement stimulated T cell function, whereas CTLA-4 suppressed T cell activation. These studies and subsequent mechanistic investigations led Dr. Allison to propose that CTLA-4 inhibition of T cells limited immune destruction of tumor 282 cells and that blockage of this receptor might unleash T cell antitumor activity. He then established models to test this hypothesis, generating blocking monoclonal antibodies to CTLA-4 and showing that these antibodies induced tumor regression in mice. The success of these preclinical studies motivated Dr. Allison to work with Bristol-Myers Squibb to develop and test a therapeutic monoclonal anti-CTLA-4 antibody (iplilimumab) in cancer patients. Treatment with ipilimumab was shown to induce remission in a subset of patients, providing further evidence of efficacy in phase II and III trials, and therefore led to FDA approval of the drug in 2011. These studies of CTLA-4 laid the foundation for development of a new class of “immune checkpoint therapies,” drugs that target T cell inhibitory pathways (e.g., pembrolizumab for PD-1/PD-L1 blockade), and changed the landscape of cancer treatment. Dr. Allison’s outstanding accomplishments have been recognized by his appointment as a Howard Hughes Medical Institute Investigator, his election to the National Academy of Sciences, the Institute of Medicine, the American Association of Arts and Sciences, the American Society of Microbiology, and as a Fellow of the AACR Academy. Likewise, he is the recipient of several prestigious awards such as the Canada Gairdner International Award, the 2013 Innovation Award for Bioscience, and two AACR awards, the AACR-Lloyd J. Old Award in Cancer Immunology and the AACR G.H.A. Clowes Memorial Award. AACR ANNUAL MEETING 2015 11_15AM_Sun_Layout 1 3/27/15 12:20 PM Page 283 PRESIDENTIAL ADDRESS Sunday, 5:30 p.m.-6:30 p.m. Hall A (200 Level), Pennsylvania Convention Center Resistance to Endocrine Therapy: Insights from Presurgical Trials in Breast Cancer Carlos L. Arteaga, MD, FAACR Vanderbilt-Ingram Cancer Center, Nashville, TN AACR President Carlos L. Arteaga, MD, is professor of medicine and cancer biology at Vanderbilt University School of Medicine, where he holds the Donna S. Hall chair in breast cancer research. He serves as associate director for translational/clinical research; director of the Breast Cancer Program; director of the Vanderbilt-Ingram Cancer Center Research Network (VICCRN); and director of Center for Cancer Targeted Therapies at Vanderbilt-Ingram Cancer Center in Nashville, TN. Dr. Arteaga’s research interests include oncogene signaling and molecular therapeutics in breast cancer with an emphasis on targeted therapies, mechanisms of drug resistance, translational research, and investigator-initiated clinical trials. Early in his career, he was the first to report the roles of IGF-I receptors and TGF beta in breast cancer progression and their use as therapeutic targets. More recent work has focused on the role of presurgical and neoadjuvant trials to discover molecular biomarkers that inform patient selection in clinical trials and/or for the discovery of mechanisms of drug resistance in breast cancer. In studies focused on hormone receptor-positive breast cancer, he showed the role of aberrant activation of the PI3K pathway in promoting escape from antiestrogens and the ability of inhibitors of HER2 and PI3K to reverse resistance to antiestrogen therapy in human breast cancer. Since 2001, he has led the National Cancer Institute-funded Vanderbilt Specialized Program of Research Excellence (SPORE) in breast cancer. His work has significant implications for novel clinical trials in patients with breast cancer. Dr. Arteaga received his medical degree in 1980 from the Facultad de Ciencias Médicas at the Universidad de Guayaquil in Ecuador. Following internal medicine residency at Emory University in Atlanta, he completed a fellowship in medical oncology at The University of Texas Health Science Center at San Antonio. Dr. Arteaga joined the faculty at Vanderbilt University in 1989. April 18-22, 2015 • Philadelphia, PA He has received many honors and awards, including the AACR-Richard and Hinda Rosenthal Award; the American Cancer Society Clinical Research Professor Award; the Gianni Bonadonna Award from the American Society of Clinical Oncology; the Brinker Award for Scientific Distinction from Susan G. Komen; and, early in his career, the Clinical Investigator Award from the U.S. Department of Veteran Affairs. In 2013, he was elected as a fellow of the American Association for the Advancement of Sciences. Additionally, he is an elected member of the American Society for Clinical Investigation and the Association of American Physicians and member of Susan G. Komen Scientific Advisory Board.
