Oncogenomics of c Myc transgenic mice reveal novel regulators of extracellular signaling, angiogenesis and invasion with clinical significance for human lung adenocarcinoma The c Myc transcription factor is frequently deregulated in cancers. To search for disease diagnostic and druggable targets a transgenic lung cancer disease model was investigated. Oncogenomics identified c Myc target genes in lung tumors. These were validated by RT PCR, Western Blotting, EMSA assays and ChIP seq data retrieved from public sources. Gene reporter and ChIP assays verified functional importance of c Myc binding sites. The clinical significance was established by RT qpcr in tumor and matched healthy control tissues, by RNA seq data retrieved from the TCGA Consortium and by immunohistochemistry recovered from the Human Protein Atlas repository. In transgenic lung tumors 25 novel candidate genes were identified. These code for growth factors, Wnt/β catenin and inhibitors of death receptor signaling, adhesion and cytoskeleton dynamics, invasion and angiogenesis. For 10 proteins over expression was confirmed by IHC thus demonstrating their druggability. Moreover, c Myc overexpression caused complete gene silencing of 12 candidate genes, including Bmp6, Fbln1 and Ptprb to influence lung morphogenesis, invasiveness and cell signaling events. Conversely, among the 75 repressed genes TNFα and TGF β pathways as well as negative regulators of IGF1 and MAPK signaling were affected. Additionally, antiangiogenic, anti invasive, adhesion and extracellular matrix remodeling and growth suppressive functions were repressed. For 15 candidate genes c Myc dependent DNA binding and transcriptional responses in human lung cancer samples were confirmed. Finally, Kaplan Meier survival statistics revealed clinical significance for 59 out of 100 candidate genes, thus confirming their prognostic value.in conclusion, previously unknown c Myc target genes in lung cancer were identified to enable the development of mechanism based therapies. (*The paper was published in Oncotarget. 2017; 8: and the abstract is a transcript of this paper.) 17

20 Florian Caiment, Ph.D Maastricht University School of Oncology & Developmental Biology Maastricht, The Netherlands Dr. Florian Caiment is Assistant professor with a main expertise is in the recently emerging next generation sequencing (NGS) technology, which allows sequencing complete genome or transcriptome of any biological material for unlimited applications. He was involved in this technology from the very beginning, initially in the lab during his phd then moving to the bioinformatics analysis during his Post Doc. This unique double expertise allows him to design innovative and coherent experiment both from the biological and the analytical point of view. Florian joined the department of Toxicogenomics in Maastricht as a postdoctoral fellow in April 2011, as a full time bioinformatician on the ASAT knowledge base project (assuring safety without animal testing). He followed up with the DiXa European project (Data Infrastructure for alternatives to animal based Chemical SAfety testing). Florian is now supervising the RNA Seq activities of the EU FP7 HeCaToS project (14 partners) as well as in the Horizon 2020 Eu ToxRisk (39 partners). Towards the Development of an Omics Data Analysis Framework for Regulatory Application Despite the expanding number of research scientific publications using omics in the field of toxicology with the exception of few cases in the domain of drug development no omics data has been used till date to support a chemical regulatory application, for instance under REACH. Regulatory agencies mainly report two major issues concerning the use of omics technologies: 1/ The high technical variance for each given technological platform, which make the data sometimes difficult to correlate within and between different platforms; 2/ The impact that the choice of bioinformatics analysis pipeline has on the results, reflected in pipeline dependent differences in the lists of biological systems significantly affected by the compounds of interest, making the truth of toxicity difficult to assess or believe from omics data. While several scientific consortium had been carried out to tackle these two main issues, notably with respect to microarray quality control (MAQC I and II) followed by sequencing quality control (SEQC), both leading to major publications in high impact factor journals, no consensus on an omics analysis framework (ODAF) for regulatory application has been achieved yet. To date, there are no OECD guidance documents available for the generation and analysis of omics data. Here, one of the major roadblocks is the lack of a standardized procedure for the analysis of the data. This results in different conclusions possibly being derived from one and the same set of data depending on the transformations and statistical procedures used. This creates an issue for regulators who are not able to assess whether the results generated from such data support the conclusions being drawn and do not have the means to verify the conclusions. In this particular context, this new project aims to regroup toxicogenomics experts to test and further develop a regulatory ODAF (R ODAF) proposal for the toxicogenomics community with the ambition to enable the regulatory bodies to consider omics as a relevant data type to support compound submissions. For this, we will focus our project on transcriptomics data, and will start by identifying, collect and review the analysis methods for all relevant toxicogenomics dataset on the three major transcriptomics platforms: microarrays, RNA Seq and TempO Seq technology (from BioSpyder). Ultimately, this project will propose a common foundation method to the regulatory agency with clear guidelines on how to recognize and discard bad quality samples (such as outliers), how to define thresholds and parameters for identifying differential expression (pvalue, multiples testing correction methods, fold change ) for each platform. 18

22 Tao Chen, Ph.D National Center for Toxicological Research U.S. Food and Drug Administration Jefferson, Arkansas, USA Dr. Tao Chen received his Ph.D. degree in Toxicology from the University of Arkansas for Medical Sciences in 1997 and received his diplomat of the American Board of Toxicology in He was a postdoctoral scientist in Duke University during He joined the Division of Genetic and Molecular Toxicology, National Center for Toxicological Research, U.S. Food and Drug Administration in 2000 as a research toxicologist. He is also an adjunct professor in several universities. Dr. Chen has served as an editor or an editor board member for more than six scientific journals. He has been a consultant in the World Health Organization (WHO) and the Organization for Economic Co operation and Development (OECD) for development of regulatory documents and a grant reviewer for the U.S. National Science Foundation and European Research Council. Dr. Chen has served as an organization committee member or a chair for a meeting or a meeting session many times. He has also been invited to present several keynote speeches and planetary lectures in national and international scientific meeting. He has published more than 130 articles in peer reviewed scientific journals and books. Dr. Chen s current approaches addresses on evaluation of mutagenicity and carcinogenicity of FDA regulated agents using next generation sequencing. Genome wide characterizations of mutations induced by genetic carcinogens using next generation sequencing Mutations are heritable changes in the nucleotide sequence of DNA that can lead to many adverse effects, such as cancers. Genotoxicity assays have been used to identify chemical mutagenicity and carcinogenicity. Current FDArecommended mutation assays, such as the Ames test and mouse lymphoma assay, predict mutagenicity of test agents in the genes that allow mutant cells to be positively selected when mutations occur in the genes. These assays only detect mutations related to the genes, but not the whole genome. The mutations induced by the test agents may bias to certain types of mutations due to the target genes natures. Although the assays have been used for many years, a new mutation assay that can directly measure all types of mutations in genome has been expected for a long time. Recently developed next generation sequencing (NGS) technology allows us to detect genome mutations in the cells directly. In our laboratory, we have used whole genome sequencing method to screen mutagens using Salmonella typhimurium TA100 cells, a bacteria system, to detect germline mutations in Caenorhabditis elegans, a worm system, and to evaluate mutational spectra in mouse lymphoma cells, a mammalian system. The results show that NGS technology can sensitively detect mutation induction caused by genetic carcinogens and effectively evaluate the different types of mutations including base pair substitutions, insertions and deletions (indels), loss of heterozygosity, and chromosome number changes, suggesting that the unparalleled advantages of NGS for evaluating mutagenicity of chemicals can be applied for the next generation of mutagenicity tests. 20

Her work has pioneered the use of network based approaches for cancer patient classification and risk stratification towards precision medicine. Towards robust clinical use of NGS in precision medicine More and more studies have indicated the utility of next generation sequencing (NGS) in precision medicine, from rare genetic disease, reproductive health, to oncology, thanks to increasing data output and decreasing costs of the technology. The vast amount of data output has brought in the promise for comprehensive diagnostic approaches but might also raise the challenge in robust clinical use. Starting from product design to validation, sample accessibility, workflow complexity, and data analysis optimization are integral parts of a robust NGS solution for clinical use. In this talk, I would like to discuss key considerations on the above vital components in developing NGS diagnostics for companion therapeutics, and use Illumina s most recent tumor profiling tool TruSight Tumor 170 as an example for illustration. 21

24 Melissa Davis, Ph.D The Walter and Eliza Hall Institute of Medical Research, Australia Dr. Melissa Davis is a computational cancer biologist, and Laboratory Head at the Walter and Eliza Hall Institute of Medical Research ( davis/). She is an expert in the analysis and reconstruction of molecular mechanisms of cancer progression and response to therapy. Her background is genetics and computational cell biology, and she currently holds a National Breast Cancer Foundation Fellowship to study molecular mechanisms of breast cancer metastasis. Dr. Davis and her team work on the analysis of large, heterogeneous datasets from national and international cancer projects and seek to discover patterns in the data that will help to target patient treatment and personalise cancer therapy. Prediction of drug efficacy in breast cancer subtypes More effective targeting of cancer therapies has resulted in dramatically improved outcomes for patients with breast cancer, however breast cancer is a heterogeneous disease with many molecular subtypes, and survival gains have not been uniform. Even for subtypes with relatively good treatment options and outcomes, patients do not show a uniform response to therapy; some patients will not respond to the standard treatment regimens indicated by their clinical presentation, and others will experience disease recurrence after initially favourable responses. Considerable work has been undertaken in recent years to develop computational models that will predict the response of a patient to therapy to improve the precision with which patients can be treated. As the collection of molecular data on individual patients becomes increasingly feasible in the clinical setting, these in silico methods have the potential to improve the precision of treatment and outcomes for patients. Gene expression data has repeatedly been shown to be the most effective kind of molecular measurement for training predictive models, exceeding the performance of genetic and proteomic data in predicting response to therapy. As such, methods that use gene expression data are likely to provide the most powerful predictions of patient response. We have generated a series of predictive models that can be used to estimate the drug sensitivity of breast cancer samples to determine which patients are most likely to respond well to a given therapy. We have also segregated patients based on molecular phenotypes, such as signalling status and epithelial mesenchymal plasticity, in addition to traditional molecular subtypes subtypes (such as basal, luminal and normal like) to identify therapies that show enhanced efficacy against specific subtypes. 22

25 Matthias Fischer, Ph.D Professor and Senior Physician Experimental Pediatric Oncology University Children's Hospital, Colonge University Cologne, Germany Dr. Matthias Fischer is a physician scientist heading the Department of Experimental Pediatric Oncology at the University Children s Hospital of Cologne, Germany. Dr. Fischer is serving as Senior Physician at the University Children s Hospital of Cologne since 2009, and was appointed as full Professor for Pediatrics in His laboratory is focused on elucidating the genetic etiology and molecular pathogenesis of neuroblastoma, a pediatric tumor of the sympathetic nervous system. In particular, Dr. Fischer and his team is applying high throughput technologies, such as massively parallel sequencing and microarray analysis, to discover relevant alterations of neuroblastoma development, to establish prognostic and predictive biomarkers, and to identify therapeutic targets. All of this work is geared to translate novel findings from basic research into clinical practice, in order to improve clinical management of neuroblastoma patients. Dr. Fischer has authored more than 100 peer reviewed publications, and served as advisory board member in several national and international committees, covering both basic and clinical research projects. The genetics of spontaneous regression and fatal progression in neuroblastoma Neuroblastoma is a pediatric tumor of the sympathetic nervous system. The clinical course of the disease varies dramatically, ranging from spontaneous regression to fatal progression despite intensive cytotoxic treatment. The pathogenesis underlying the distinct phenotypes, however, has been poorly understood to date. To determine the molecular mechanisms of favorable and unfavorable courses, we performed massively parallel sequencing of 416 untreated neuroblastomas. We detected genomic alterations of 17 genes related to the RAS and p53 pathways in 73/416 patients. The presence of these mutations was strongly associated with dismal outcome in the entire cohort, as well as in the clinical high risk and non high risk subgroups. We noticed, however, that the prognostic effect of RAS/p53 pathway mutations was strictly dependent on the occurrence of telomere maintenance mechanisms. Survival of patients whose tumors were telomere maintenance positive was dramatically inferior when additional RAS/p53 pathway mutations were present as compared to those without such alterations. By contrast, all patients whose tumors lacked telomere maintenance mechanisms have survived to date, and spontaneous regression or differentiation into ganglioneuroblastoma occurred both in the presence and absence of RAS/p53 pathway mutations. Our data suggest a precise definition of clinical neuroblastoma phenotypes: High risk tumors are characterized by telomere maintenance activation, and additional mutations in RAS or p53 pathway genes delineate a patient subgroup with devastating outcome. By contrast, patient outcome is excellent in the absence of telomere maintenance, and mutations in RAS/p53 pathway genes fail to establish fully malignant tumors in this subgroup. Together, our results emphasize the importance of activating telomere maintenance mechanisms in the development of human malignancies, and provide a starting point for refined risk assessment and new therapies in neuroblastoma. 23

Closing the Reproducibility Gap with Standards and Best Practices Irreproducible basic biological research is a tremendously expensive and global problem. The inability to reproduce experimental data in preclinical studies has resulted in the invalidation of research breakthroughs, retraction of published papers, abrupt discontinuation of clinical studies, and reduced trust in the research and development enterprise. More importantly, valuable time and critical resources are wasted by irreproducibility as opportunities to enhance human health are delayed or simply lost. Although the causes of irreproducible preclinical research are complex, they can be traced to cumulative errors/flaws in one or more of the following areas: 1) study design, (2) biological reagents and reference materials, (3) laboratory protocols, and (4) data analysis and reporting. This presentation will use examples of how biological reagents, specifically cell lines and antibodies, impact irreproducibility in preclinical research and how the implementation of consensus based standards to authenticate these critical and widely used reagents will lead to both increased rates of reproducibility and dramatic returns on research funding investments. 24

PersonALL towards treatment personalization in molecular diagnostics of acute lymphoblastic leukemia for Polish children Aleksandra Gruca 1, Roman Jaksik 2, and Marek Sikora 1,3 1 Institute of Informatics, Silesian University of Technology, Gliwice, Poland 2 Institute of Automated Control, Silesian University of Technology, Gliwice, Poland 3 Institute of Innovative Technologies EMAG, Katowice, Poland Acute lymphoblastic leukemia (ALL) is the most frequently occurring childhood cancer, comprising approximately 30% of all pediatric malignancies. Each year, diagnosis of ALL is established in approximately 200 children in Poland. They are all treated uniformly according to European standards in the centers of the Polish Pediatric Leukemia/Lymphoma Study Group (PPLLSG). The results of the last treatment protocol ALL IC BFM 2009 were very good with overall survival >90%. Nevertheless, >10% of all patients suffered from ALL relapse and required additional intensive treatment including hematopoietic stem cell transplantation (HSCT). Here we present the information system and data workflow that is developed within the PersonALL project a collaborative project among the PPLLSG centers that focuses on research on molecular mechanisms of ALL, aiming into improved diagnostics, classification and, finally, treatment personalization. The system is dedicated to store and analyze heterogeneous data collected from different clinical centers, integrate results from molecular biology analysis and clinical information to assess the prognostic and therapeutic relevance of different diagnostic parameters. Collected data will cover aspects such as genomics, transcriptomics, 25

28 cytogenetics, fluorescent in situ hybridization (FISH) and immunophenotyping as well as selected clinical information and applied therapy. The main challenge is to link all this heterogeneous information into a comprehensive expert system, which enable rapid recognition of the features associated with treatment outcome. The system will provide uniformed access to the data, allowing the biologists and clinicians to analyze it from different aspects and summarize into useful information. The users will be provided with analysis assistant a set of advanced analytical tools in a form of a simple GUI interface allowing statistical and data mining analysis. Proposed workflow for data integration and analyses will allow grouping the patients according to certain criteria in order to discover discriminant features for the groups (including the relevance of the features) related to the treatment outcome. The overall result of the PersonALL project will be development of innovative diagnostics of childhood ALL that should enable more targeted therapies and lead towards improved treatment outcome. 26

Reliability of Whole Exome Sequencing for Assessing Intratumor Genetic Heterogeneity in Breast Cancer Multi region sequencing is used to detect intratumor genetic heterogeneity (ITGH) in tumors. To assess whether true ITGH can be distinguished from sequencing artifacts, we used whole exome sequencing (WES) of three anatomically distinct regions of the same tumor, and also the same DNA twice to estimate technical noise. Somatic variants were detected with three different WES pipelines (tumor only, cohort normal, matched normal) and subsequently validated by high depth amplicon sequencing. The cancer only pipeline was unreliable, with about 69% of the identified somatic variants being false positive. Even with matched normal DNA where 82% of the somatic variants were detected reliably, only 36% 78% were found consistently in technical replicate pairs. Overall 34% 80% of the discordant somatic variants, which could be interpreted as ITGH, were found to constitute technical noise. Excluding mutations affecting low mappability regions or occurring in certain mutational contexts was found to reduce artifacts, yet detection of subclonal mutations by WES in the absence of orthogonal validation remains unreliable. 27

We will also discuss lessons learned in handling and integrating custom and open source software, building appropriate validation datasets and scenarios, and regulatory compliance. 28

31 Paweł Łabaj, PhD Austrian Academy of Sciences APART Fellow, Vienna, Austria Chair of Bioinformatics Rsearch Group, Boku University Vienna, Austria Bioinformatics Group Leader, Malopolska Centre of Biotechnology, Jagiellonian University, Krakow, Poland Paweł Łabaj has studied Computer Science in Medicine at Silesian University of Technology (Gliwice, Poland). For his MSc thesis he was working on the project in The Institute of Medical Technology and Equipment (Zabrze, Poland) where he has developed system of automatic analysis and pattern recognition using neural networks applied in Fetal Heart Rate monitoring devices. He then has joined the Vienna Science Chair of Bioinformatics at Boku University Vienna, where he obtained PhD in Bioinformatics on Measurement and data analysis in the face of noise and complex backgrounds Advances from improved bioinformatics algorithms. He was active member of FDA MAQC III/SEQC consortium where he studied performance of the platforms and pipelines for high throughput expression profiling. This experience has led to winning the APART Fellowship of Austrian Academy of Sciences as well as recent competition for bioinformatics group leader at Malopolska Centre of Biotechnology (Krakow, Poland). Dr Łabaj s research focuses on consequences of gene vs. alternative transcript expression profiling, as well as on the approaches for assessing performance / benchmarking of the platforms and analysis pipelines. Power and limitations of RNA Seq Putting reproducibility to the test The MAQC/SEQC consortium has recently compiled a key benchmark that can serve for testing the latest developments in analysis tools for microarray and RNA seq expression profiling. Such objective benchmarks are required for basic and applied research, and can be critical for clinical and regulatory outcomes. It is invaluable in times when about 90% of questioned scientists has confirmed that there is reproducibility crisis in science and it is estimated that 85% of research resources are wasted. This rich and publicly available benchmark enables to identify the underperforming computational tools which are the major offender in science s reproducibility crisis. In our recent research work we are going beyond the first comparisons presented in the original SEQC study. We have demonstrated the benefits that can be gained by analysing results in the context of other experiments employing a reference standard sample. This allowed the computational identification and removal of hidden confounders, for instance, by factor analysis. In itself, this already substantially improved the empirical False Discovery Rate (efdr) without changing the overall landscape of sensitivity. Further filtering of false positives, however, is required to obtain acceptable efdr levels. Appropriate filters noticeably improved reproducibility of differentially expressed calls both across sites and between alternative differential expression analysis pipelines. 29

He got his Ph.D. from Peking Union Hospital College in July, He is responsible for proficiency testing of immunoassay and nucleic acid testing of infectious diseases, pharmacogenomics and tumor gene mutation detection for clinical laboratories in hospitals of China. His research interesting is major in the methodology and standardization of molecular diagnosis and immunoassay. He had got six grants from The National Natural Science Funds Fund, one grant from the National High Technology Research and Development Program of China 863 program and AIDS and hepatitis, and other major infectious disease control and prevention Program of China respectively as the project principal. He has published 108 papers in academic journals (Ann Rheum Dis., Clin Chem., J Mol Diagn., J Clin Endocrinol Metab., Int J Cancer, J Thorac Oncol. and so on). Quality control and standardization of precision oncology related gene mutation detection in China Precision oncology takes advantage of individual differences in a patient s tumor biomarkers, which are associated with patient prognosis and tumor response to therapy, and applies this information to better inform medical care. Tumor biomarkers can be DNA, RNA, protein and metabolomic profiles (Panomic analyses) that predict therapy response. However, the most recent approach is the detection or sequencing of tumor DNA, which can reveal genomic alterations that have implications for cancer treatment. Since 2012, the National Center for Clinical Laboratories has established more than 10 external quality assessment(eqa)/proficiency testing(pt) programs, which include gene mutations in EGFR, KRAS, BRAF, PIK3A, Her2 (FISH), EML4 ALK(FISH and RT PCR), BCR ABL(qRT PCR), ctdna (ARMS, ddpcr and NGS) and multiple gene detection by NGS,based on reference materials or controls developed in our laboratory. In the beginning of each program, only nearly half of participants get satisfactory results. Most of the participants reported false positive and false negative results, especially in false positive. Now, improvement of quality has been achieved greatly because of implement of quality control measures in clinical laboratories and training program of personnel. The EQA/PT program for bioinformatics pipeline (dry bench process) of NGS (whole whole genome sequencing, whole exome sequencing and targeted sequencing)is being prepared based on the reference materials developed in our laboratory. 30

33 Hiroki Nakae, Ph.D Director General Japan Multiplex bio Analysis Consortium (JMAC) Tokyo, Japan Dr. Nakae is Director General of an Japanese industrial consortium in the field of biotechnology, called JMAC (Japan Multiplex bio Analysis Consortium). JMAC is a unique industrial consortium consisting wide variety of companies including microarray manufactures, material providers, plastic processing technology providers, trading companies and consultants, pursuing the common target, namely industrialization of biotechnology. The major activities of JMAC are to support large research projects from the standpoint of quality control and to develop international standard by taking in the outcome of the project works. The representative project is Project focused on developing key technology for discovering and manufacturing drugs for next generation treatment and diagnosis supported by AMAD in JAPAN. He is leading the development of the quality control system including mirna standard materials collaborating with AIST (National Institute of Advanced Industrial Science and Technology) in this project. For the development of international standards, he is leading and supporting the development of over 10 ISO standards in broad areas of industries. He is an expert member of TC 212 (Clinical laboratory testing and in vitro diagnostic test systems), TC 34/SC 16 (Horizontal methods for molecular biomarker analysis), TC 276 (Biotechnology), TC 229 (Nanotechnologies) and a formal liaison observer among these committees and to another TC and SC such as TC 34/SC 9 (Microbiology), TC272 (Forensic sciences). Dr. Nakae is also an assessor of medical laboratory accreditation program based on ISO 15189, belonging to Japan Accreditation Board (JAB). International standardization activity on emerging technologies for medical and food industries An ISO perspective The MAQC/SEQC project had been started in order to discuss the quality issues in submitted data for the application of drug approval. In the project, multi platform measurement data were analyzed and discussed by broad approaches including multi laboratory testing, software pipeline comparison and statistical analysis of the outcomes of the genome wide analysis systems. One of the goals of the project was to reach a consensus for the emerging technologies to ensure the quality of data and to maintain the compatibility to understand the accuracy of the submitted data. For precision medicine, companion diagnostics play an important role for selecting medicines for each person based on his/her genetic background. In this sense, the accuracy of IVD is the key issue for the realization of precision medicine. Quality control of IVD needs another aspect other than the issues discussed in the series of discussion in MAQC/SEQC. The testing is performed not only in selected high level laboratories, e.g. laboratories of pharmaceutical companies, but also in a large number of small clinical laboratories all over the world. The standards play a significant role in controlling such general laboratory works for realizing the society of precision medicine. For example, ISO clearly states The laboratory shall validate examination procedures derived from the following sources; a) non standard methods;, and Validated examination procedures used without modification shall be subject to independent verification by the laboratory. In addition, the procedure to record the metrological traceability of the calibration standard and the calibration of the item of equipment shall be 31

34 documented. Thus, the reference material is the key tool not only for equipment calibration, but also for preparing the quality control materials to be used for each measurement method. Standardization would be helpful for such kind of quality control in clinical laboratories for sustaining compatibility of the results of molecular testing. Presently, many standardizations of molecular testing are going forward in the ISO world. ISO is an international organization for standardization. It develops and publishes International Standards in many fields of technologies other than the electrical industry. In order to cover the wide variety of industries, specific TCs (Technical Committees) are formed on the technology and industry field base. Member bodies (countries) assign experts for each TC, who participate in discussions to develop International Standard documents are developed by the assigned experts according to ISO directives. Japan Multiplex bio Analysis Consortium (JMAC) was mainly established to actively engage in the development of ISO standards by providing formal experts to the ISO/TCs and advising any other experts in the field of biotechnology. JMAC has provided such activities to TC 212 (Clinical laboratory testing and in vitro diagnostic test systems), TC 34/ SC 16 (Horizontal methods for molecular biomarker analysis), TC 276 (Biotechnology), and TC 229 (Nanotechnologies). Emerging technologies related to MAQC / SEQC meetings are also discussed In the ISO world. Especially, the major technology NGS is under discussion in TC 212, TC 34/SC 16, TC 34/SC 9 (Microbiology), and TC 276. Briefly, the preparation for starting a formal development of guidance documents related to the introduction of emerging technologies into clinical laboratories has been underway in TC 212. In TC 34/SC 16, a document for application of NGS to identify animal species in food and feed has been prepared. In TC 34/SC 9, a standard for the whole genome sequencing of foodborne pathogen genome mainly by NGS is being discussed. In TC 276, two documents for NGS are currently under development. One document is ISO/AWI , entitled Biotechnology General requirements for massive parallel sequencing Part 2: Methods to evaluate the quality of sequencing data, and the other is a document for the pre analysis phase of NGS analysis. Details of these works will be introduced in my talk. The emerging technology including NGS or massive parallel sequencing is a powerful tool for many industrial fields including medical and food industries. For industrial use of emerging technologies, quality is a very important issue that should be discussed, not only for approval of IVDs, but also for the daily management of the test results, namely from approval to lab. MAQC has been focusing on the development of regulation science regarding quality control of data for application. Now it should expand its scope to the infrastructure for controlling the quality of testing in clinical laboratories. MAQC/SEQC should carefully watch the ISO standardization activity and collaborate with them for future works in order to achieve the common goal; assurance of test quality for emerging technologies. 32

He is also a Commissioner on Human Medicines. His research focuses on personalised medicine in order to optimise drug efficacy and minimise toxicity, move discoveries from the lab to the clinic, and from clinic to application. He has authored over 420 peer reviewed publications, and has a H index of 85. Pharmacogenomics and precision medicine current and future perspectives Pharmacogenomics is the study of how genetic variation affects drug responses. Precision Medicine is a wider term also encompassing other technologies that personalise therapeutic and preventive approaches. However, pharmacogenomics is an important component of precision medicine and needs to be considered alongside other aspects to ensure patients get the right drugs at the right time and at the right dose. Pharmacogenomic variation can affect drug pharmacokinetics or drug pharmacodynamics, and is important for both drug efficacy and drug safety. Crucial to both is precision dosing. Individual dose requirements vary, but are not currently accounted for in clinical practice. The one dose fits all paradigm leads to marked variability in exposure, and therefore in drug responses. Development of novel dosing algorithms and their clinical implementation is now being undertaken for certain drugs such as warfarin. The greatest success in efficacy studies for pharmacogenomics has been in the development of targeted agents in cancer and rare diseases. In the former, drugs targeting somatic mutations have had major impact in certain malignancies, but the challenge for the future will be to ensure the use of combinations of drugs to ensure that any response is durable. In rare diseases, drugs targeting novel mutations, for example ivacaftor for the G551D mutation in cystic fibrosis, have had a transformational effect on patients lives. There have been important advances for drug safety pharmacogenomics, notably in determining the role of HLA gene polymorphisms in predisposing to serious immune mediated adverse drug reactions. To date almost 30 novel HLA allele associations have been identified, and this number is increasing. Non HLA gene polymorphisms are also being identified now, and this will be an area of growth in the future. In the future, as more patients have their whole genome sequence, the challenge will be to ensure that both common and rare genetic variation is taken into account in optimising drug responses. With all these developments, the greatest challenges for all healthcare systems will be to deliver these advances in a costeffective and sustainable manner that is acceptable to both patients and the public. 33

A General Framework for Analysis of Clonal Heterogeneity and Tumor Evolution The evolution of subclones during cancer progression due to accumulation of a number of somatic mutations represents Intra tumor heterogeneity. Despite recent advances, determination of sub populations within a tumor remains a challenge. Here, we address this problem through designing a computational workflow for identifying the sub populations within a tumor. The workflow infers clonal populations and their frequencies from bulk tumor samples. It profiles a reliable set of for somatic copy number alterations and point somatic mutations along with allele specific coverage ratios between the tumor and matched normal sample, estimates cellular fractions of them, identifies and evaluates the clustering of the mutations, infers clonal ordering, and visualizes and interprets the results. The analysis workflow will be presented in detail as well as results from simulated datasets and NGS sequencing data from a CLL cancer study, to demonstrate the efficiency of the analysis pipeline. 34

Evolution of the breast cancer genome under immune surveillance Tumor infiltrating lymphocyte (TIL) count and gene expression signatures that reflect the extent of immune infiltration in the tumor microenvironment has long been recognized as prognostic markers in early stage triple negative (TNBC), HER2 positive, and highly proliferative estrogen receptor (ER) positive breast cancers. Extensive immune infiltration in the tumor microenvironment also predicts for greater chemotherapy sensitivity. It has been suggested that high mutation load and consequently, large number of potentially immunogenic new antigens drive immune infiltration in cancer. However, in breast cancer higher TIL counts and greater immune metagene expression is associated with significantly lower clonal heterogeneity in all breast cancer subtypes and with a trend for lower overall mutation, neoantigen and CNV loads in TNBC and HER2+ cancers. The high immune gene expression and lower clonal heterogeneity suggest an immune pruning effect and equilibrium between immune surveillance and clonal expansion. This suggests that anti tumor immune surveillance in immune rich tumors leads to elimination of clones, lower clonal heterogeneity and simpler genomes. The surviving neoplastic cell population exists at a near equilibrium with the immune surveillance explaining the better prognosis of these cancers. The higher genomic diversity of immune poor TNBC suggest escape from immune surveillance and genomic diversification. When we examined the immune microenvironment of paired primary tumors and metastasis, most immune cell subtypes, immune functions, and immune associated gene expression were lower in metastases compared to primary tumors, consistent with immune escape. These immunological differences suggest that immunotherapy will be more effective in early stage disease than in metastatic cancers. While breast cancer metastases are immunologically more inert than the corresponding primary tumors, several immune oncology targets, macrophage and angiogenesis signatures show preserved expression in metastases suggesting rational therapeutic combinations for clinical testing. 35

39 Terry Speed, Ph.D. Walter and Eliza Hall Institute of Medical Research Australia Dr. Terry Speed completed a BSc (Hons) in mathematics and statistics at the University of Melbourne (1965), and a PhD in mathematics at Monash University (1969). He held appointments at the University of Sheffield, U.K. ( ) and the University of Western Australia in Perth ( ), and he was with Australia s CSIRO between 1983 and In 1987 he moved to the Department of Statistics at the University of California at Berkeley (UCB), and has remained with them ever since. In 1997 he took an appointment with the Walter & Eliza Hall Institute of Medical Research (WEHI) in Melbourne, Australia, and was 50:50 UCB:WEHI until 2009, when he became emeritus professor at UCB and full time at WEHI, where he headed the Bioinformatics Division until His research interests lie in the application of statistics to genetics and genomics, and to related fields such as proteomics, metabolomics and epigenomics, with a focus on cancer and epigenetics. Using Mandel s row linear model in the omics era In a landmark 1959 paper (Technometrics 1: ) entitled The Measuring Process, the statistician John Mandel from the US National Bureau of Standards in Washington, DC presented the theory for what he later called the row linear model for the analysis of two way arrays of measurements made on the same set of units (materials) across a number of laboratories. A companion paper published at the same time in the American Society for Testing Materials (ASTM) Bulletin discussed practical and computational aspects of his method. Mandel s focus was interlaboratory studies of a single test method, and his method is now embodied in ASTM Standard E691. Interestingly, his model can also be used with data from studies of different measurement methods in a single laboratory, or studies involving multiple methods and laboratories. Note that in Mandel s interlab studies, a single measurement (perhaps replicated) such as of sulfur in petroleum was taken on each unit in each lab. All of the preceding notions can be applied with little change to the MAQC enterprise, where method is replaced by platform (e.g. one of several microarray platforms, sequencing or qrt PCR assays). But there is one major difference: instead of a single measurement being taken on each unit (e.g. sample of cells) in each lab or by each platform, as was normal 60 years ago, these days we might take hundreds (qrt PCR), thousands (gene expression microarrays), or millions (DNA methylation) of measurements on each unit in each lab with each platform. Mandel s method remains relevant, and illuminating, but we need to address the multiplicity of measurements on each unit. This talk will summarize a recent study involving measurements on cell samples using multiple microarray and sequencing assays measuring gene expression and DNA methylation, where we have adopted Mandel s row linear model to the omics era. Also, relevant to MAQC, Mandel s approach works best with a good number of different samples spanning a wide range of measurement values, and it becomes stronger the more labs or platforms are used on the these samples. 37

Intratumoral heterogeneity and clonal selection of breast cancer Breast cancer is the most common cancer diagnosed in women, and approximately one in eight women living in the United States has a lifetime risk of developing the disease. Breast cancer is also one of the most studied solid tumors and has the potential to being tractable to a precision medicine approach. It has been well established that these tumors are extremely heterogeneous, so intra and inter tumoral heterogeneity are the basic characteristics of breast cancer. According to gene expression profiles, breast cancer can be divided into several molecular subtypes, including luminal breast cancer, HER2 positive breast cancer, and triple negative breast cancer (TNBC). For each subtype, there are unique tumor biology characteristics and treatment strategies. Intrinsic subtypes are associated with different gene expression and mutation profiles as well as different prognoses and responses to therapies. In the era of precision medicine, therapies are being developed using the framework of molecular subtyping. Here, we summarize the major challenges and possible solutions of treating the intratumoral heterogeneity of breast cancer. 38

41 Chunlin Xiao, Ph.D National Center for Biotechnology Information (NCBI) National Institute of Health (NIH), USA Dr. Chunlin Xiao is a Staff Scientist at National Center for Biotechnology Information (NCBI), National Institute of Health (NIH). His primary role is to deal with large scale sequencing data analysis and management involving next generation sequencing technologies, such as 1000Genomes Project, Genome in a Bottle project, and Sequence Quality Control project. His research interests include population genetics, reference material and reference sequence dataset development, structural variation detection method development, and cloud computing. Performance assessment of de novo assembly based structural variation detection in the human genome Structural variations (SVs) contribute to genetic diversity of human populations, affect biological functions, and cause various human disorders. However, accurately identifying SVs with correct sizes and locations in the human genome remains challenging due to the complexity of the human genome, limitations of sequencing technologies, and drawbacks of analysis methods. The advancement of next generation sequencing technologies has dramatically decreased the sequencing cost, while substantially increased the lengths of the sequencing reads. Thus, using de novo assembly based approaches for discovering a full spectrum of SVs in human genome becomes appealing. While various assembly methods have been developed and proposed for general use by the community, the relative efficiency and predictive accuracy of SVs calling based on these assembly methods have not been fully evaluated. In this study, we applied several popular de novo assembly tools to the sequencing read data that were generated using multiple sequencing technologies with technical replicates for NA12878/HG001, a well studied individual from NIST led Genome in a Bottle (GIAB) project; an HapMap Caucasian trio and a Chinese Quartet from FDA led Sequencing Quality Control Phase II (SEQC2) project. Assemblies and SVs callsets were generated for each of the samples, and repeatability in the SVs of the technical replicates and reproducibility across sequencing sites were evaluated. These results allow better understanding of the impacts of de novo assembly methods on SVs calling, thus providing a better insight to precision medicine. 39

Objectives: The goal of this project is to provide practical examples and guidelines to help scientists make their own research fully reproducible. From the diversity of studies and tools will emerge templates that could be used to ensure full reproducibility of future studies. Background: Biomedical science is undergoing a reproducibility crisis where the results of many studies cannot be reproduced by independent investigators, or even the original authors. While reproducing biological experiments is difficult, computational analyses can be reproduced. However, the amount of data and the complexity of the analysis pipeline is ever increasing, making computational reproducibility challenging. There exist many ways to make the computational analyses of a given study fully reproducible. Size and accessibility of the data, software tools and computing resource requirements are among the factors that will define how an analysis can be made fully reproducible. There is a dire need for practical guidelines to make biomedical studies more reproducible. Specific Aims Aim 1: Identification of candidate studies. The MAQC Society asks its members to share examples of manuscripts that can be fully reproduced. 42

To set quality standards and performance metrics that can be used by regulatory agencies to certify machine learning algorithms for use in patient management. To develop a framework for comparison of machine learning algorithms to determine precise quantitative metrics of other breast cancer biomarkers, like Ki67. 44

47 Background: At present, in early stage disease clinico pathological risk stratification is performed using a limited set of features such as tumor size and lymph node status. Very large adjuvant trials such as ALTTO and APHINITY that have applied these stratification schemes have illustrated the key problems with the current classification scheme it does not stratify patients with sufficient granularity to permit selection for clinical trials. The current scheme also takes the approach of placing patients on a continuum of risk. This is at odds with results from high throughput technologies such as gene expression profiling and genomic assays, which focus on identifying individual patient groups with particular clinical behaviour. Several results in this area have identified genomic, transcriptomic or proteomic features which in hindsight are associated with particular histological features. This suggests that the histological appearance of a tumor represents a useful cancer phenotype which can be further explored, and contribute to staging and stratification. Machine learning refers to the general computational approach whereby data is used by algorithms to develop predictive models. These models are finely tuned to optimize accuracy and generalizability as applied to new data. Although machine learning existed for some time, more recently, advances in algorithm development and hardware infrastructure has enabled deep learning approaches. Deep learning was originally designed to mimic the neural architecture of the human brain, and conceptually uses a series of connected nodes (neural nets) which respond to input in a way that is tuned with repeated cycles of learning. Neural nets have the ability to learn rich representations of complex data, which may contain hierarchical and non linear relationships. These abilities make neural nets ideally suited to image classification. They have exhibited spectacular results in this area, often matching the performance of experts in the field or exceeding it (superhuman capabilities). With recent advances in deep learning provides a path forward for numerous applications in digital pathology. On one level, the robust performance and training characteristics of deep learning allows us to develop accurate automated assays for pathological features such as grade and lymphocyte infiltration. These have the potential to be learn once, apply everywhere. This is in contrast to existing imaging methods, which lack the precision and robustness to be used in the clinical setting. If the promise of deep learning can be validated, the use of digital pathology would aid pathologists in routine reporting, and could be expected to improve the validity of current pathology based clinico pathological features. In the short term, digital pathology would also help standardize pathology results within and across trials given the time required for pathology assessed quantitative metrics. TILs have been shown to be a reliable and reproducible marker of tumor immunogenicity in breast cancer. It is clear that higher levels of TILs are associated with improved prognosis in early stage TNBC and HER2 positive breast cancer, as well as a higher probability of achieving pcr in the neoadjuvant setting. Analysis of TILs in residual disease specimens after neoadjuvant therapy has also been shown to have prognostic value. The evaluation of TILs as a biomarker in breast cancer is likely to be extended from the research domain to the clinical setting in the near future. The assessment of TILs by digital image analysis might be useful for standardization in the future, since this approach has the potential, for example, to determine the number of TILs per mm² stromal tissue as an exact measurement contrary to the approximate semi quantitative evaluation suggested at this moment. In the first International Guidelines on TIL assessment in breast cancer we proposed to develop an inter laboratory Ring study to assess the reproducibility and clinical validity of TILs assessment, including machine learning algorithms. While TILs have been measured morphologically and have been shown to add predominantly prognostic information, methodological open questions in the morphological evaluation of TILs still remain, for example the assessment and importance of spatial TIL heterogeneity. The measurement on H&E stained slides most likely represents the 45

48 beginning of the efforts to use infiltrating cell properties as companion diagnostic tests. Thus, as a field, we should be open to the introduction of molecular methods, most likely in situ, that can classify the TILs component and bring higher levels of information to the patient sample. However, at this time, these deep learning approaches are still experimental and not sufficiently documented for introduction into standard practice. On another level however, deep learning also permits discovery of image based features which may be very difficult for current approaches to identify, particularly if they only exist in small groups of patients. The key benefit of deep learning here is to rapidly identify pathological features in clinical trials that are predictive of treatment or prognostic of outcome in a standardized way. This is an essential first step in deciding if previously undescribed pathological features are clinically relevant, and is largely infeasible using current approaches. Deep learning also permits modification and retraining of the feature set to optimize accuracy and interpretability, which is again infeasible with current methods. The Working Group is therefore proposing a collaboration with the Massive Analysis and Quality Control Consortium ( characterizing tumor infiltrating lymphocytes using machine learning algorithms. Developing a machine learning based assay for tumor infiltrating lymphocytes would enable rapid expansion of this promising pathological feature, and by providing an adjunct to human pathologists, enhance the validity and robustness for prognosis/prediction. Specific Aims: Comparison of the machine learning image classification metrics with those of pathologists in the RING study which the Working group has published (Carsten Denkert et al., Mod. Pathol. 2016) Comparison of automated TILs scoring with pathologist scoring results in different settings, namely core biopsies, full sections, pre invasive (DCIS), untreated and treated tumors. Comparing the performance of deep learning approaches to identify complex features such as clustering/spatial statistics including proximity of TILs to cancer cells that are prognostic of outcome or predictive of treatment. Comparing the clinical validity of different machine learning algorithms, the utility of combining models for improved accuracy and to identify possible false positives and false negatives. To combine annotated training data from different sites to create a comprehensive breast cancer ML training and validation data base hosted by the consortium. A framework will be developed to facilitate automated testing, validation and certification of image classification derived pathology metrics that can improve the standard of care. Develop together with both groups a kind of review, perspective or opinion paper on the use of Artificial Intelligence/machine learning tools in Oncology, focusing but not exclusively on TILs and including the quality requirements for use of these technologies in a clinical trial and daily practice setting, similar in kind as the Lisa Mc Shane paper in Nature Criteria for the use of omics based predictors in clinical trials, doi: /nature12564, Nature 2013, which is an exercise that may be very useful for regulatory (FDA; EMA). If we pursue this idea, we should aim for a high level journal like Nature, Nature Biotechnology, Nature Reviews Clinical Oncology or Nature Reviews Drug Discovery. 46

49 Study Design: Breast cancer slide sets in different settings (invasive, DCIS, residual disease) with known TIL assessment by pathologists will be posted on the website of the International Immune oncology Biomarker Group. A clinical trial slide set, with clinical annotation, will be hosted on the website of the International Immuneoncology Biomarker Group. All these slides can then be assessed by all participating groups. The metrics assessed will be reported on pre specified formats to the coordinators. A systematic comparison of the output of the machine learning/deep learning approaches with the pathologists score will be performed in all datasets and eventual added clinical validity to the pathologists TIL score will be evaluated using the clinical trial datasets. Timeline: The project is aimed to start in 2019 and aims to be finished within 1 year from the start of the program. Results will be presented at the annual meeting of the International Immuno Oncology Biomarker Working Group held at the San Antonio Breast Cancer Conference and at the annual MAQC Conference. Publication is aimed within 6 months after completion of the program in a high level journal. 47

52 Background Emerging big data technologies has changed our way of studying disease and health, and reproducibility is the foundation for translating the high throughput omics approaches to clinical utilities. However, errors may come from the generation, analysis, and interpretation of multi omics data. Well characterized reference materials are essential to understand the sources of errors, calibrate the measurements, and evaluate the performance of highthroughput omics tests. We are generating the Chinese Quartet reference materials at the levels of DNA, RNA, proteins, and metabolites. We are also generating multi omics datasets using different platforms at various laboratories. Therefore, it s time for the community wide efforts to establish the multi omics benchmarking values and metrics to assess the reproducibility and performance. In addition, multi omics integrative analyses will improve the reliability of the benchmarking values and the interpretations. The MAQC Society s guideline for quality control and standardization using reference materials and datasets will make massive analysis technologies more reproducible in the future by improving laboratory proficiencies. Specific Aims: Aim 1: Benchmarking values for the Chinese Quartet multi omics references. Jointly analyze the Chinese Quartet multi omics datasets to characterize the benchmarking for genomic, transcriptomic, proteomic, and metabolomic values for the DNA, RNA, protein, and metabolite reference materials, respectively. Aim 2: Performance metrics. Develop performance metrics to assess the reproducibility and performance of high throughput omics platforms, tests, and laboratories, including accuracy, precision, sensitivity, specificity and reference intervals. Aim 3: Guidelines for QC/standardization using reference standards. Develop guidelines to help the community using reference materials and reference datasets to quality control the whole process of highthroughput omics assays. Study Design The Chinese Quartet multi omics reference materials (DNA, RNA, proteins, and metabolites) were generated simultaneously from the same set of immortalized cell lines including father, mother, and two monozygotic twin daughters. The genetic ground truths from the quartet family and the multi omics integrative analyses will make the benchmarking values more reliable. Timeline Generate multi omics data using different platforms Jointly analyze the datasets Establish the benchmarking values and develop the performance metrics Validate selected reference values using orthogonal methods 50

53 Chen Ding, Ph.D Fudan University Shanghai, China Professor Chen Ding is the doctor of Cell Biology for the School of Life Sciences at University of Science and Technology of China. He was selected in National One Thousand Young Talents Program and Beijing High level Oversea Young Talents Project. He is the executive member of the council of Chinese Human Proteome Organization (CNHUPO). He focuses on the development of in depth proteome platform, standardization and its applications on biological researches, with special emphasis on transcriptional regulation, signal transduction, and liver biology. His studies published in Nature Biotechnology, Cell, Molecular Cell, Nature Communications, Proceedings of the National Academy of Sciences of the United States of America, Journal of Experimental Medicine, and Mol Cell Proteomics as research articles. Project #4: QC/standardization of proteomics materials and technology The project coordinator: Chen Ding Fudan University Jun Qin National Center for Protein Sciences Beijing Objectives/Goals: To establish a reference proteome standard material and SOP for measure the proteome across different MS instruments and in different labs of different locations Background: The Human Proteome Project has promoted the development of proteomics and made it an indispensable tool for research in life sciences and medicine. Improvements in the next generation proteomics including instrumentation, sample preparation, and computational analysis, have facilitated the generation of data that cover protein profiling, post translational modifications (PTMs), and protein protein interactions (PPIs). It is crucial to measure samples with reproducibility. This is challenging in proteome research. Thus, a uniform standard reference material, a standard operating procedure (SOP) and a reference dataset that may facilitate measurement validation cross different labs lab are in urgent needs. phase I of the Microarray Quality Control (MAQC I) tested agreement across sites and platforms for geneexpression microarrays; MAQC II surveyed approaches in microarray based predictive model development to understand sources of variability in prediction performance, to assess the influences of endpoint signal strength in data and to develop good modelling practice guidelines; The Sequencing Quality Control project (SEQC/MAQC III) assessed the performance of RNA seq across laboratories and to test different sequencing platforms and data analysis pipelines. Comparing with the genome, transcriptome and microbiome, relatively few proteomic studies have evaluated data reproducibility across laboratories to identify potential measurement variability in each step of proteome general workflow. This probably because: (i) The proteomics field lacks uniform standard reference material; (ii) Laboratories differ in methods for samples preparation; (iii) Data quality is affected by different data acquisition methods; (iv) Subsequent analysis has no consistent evaluation systems, etc. 51

54 To solve these problems, we initiate the proteome standard initiative that focuses on the research in a proteome standard for quality control, aiming to establish the first international proteome standard reference material with a standard operating procedure (SOP) and generate the first international proteome benchmark dataset for assessing variation in proteome analysis. A rigorous proteome standard and SOP and quality control system will be enacted to ensure the reliability and reproducibility for measuring proteomes, accelerating the development of life sciences and medicine. Specific Aims: (i) To establish a proteome standard reference material; (ii) To establish a proteome standard operating procedure; (iii) To generate a proteome benchmark dataset. Study Design: (i) We performed 1200 repeating measurements of a 293T cell line proteome with 10 different LC MS instruments with a relatively fixed LC method and column in one year time span as our routine QC for the Phoenix Center proteomics technology platform. We found that the results from the same instruments tended to cluster together, i. e. batch effect from different instruments. We will analyse these data in a fashion of big data to generate a preliminary SOP so that measurements across different mass spectrometers can be compared independent of operators and instruments. a) Quantification values of each peptide/protein are calculated and corrected using different normalization methods to generate distribution curves for each peptide and proteins from the same instrument. We will then perform outlier analysis based on Gaussian mixture model (GMM) to reject outliers and to determine a reference index of each peptide/protein within 95% confidence intervals. b) Then, Identify peptides and proteins whose quantification are independent of or insensitive to instruments and operators. These peptides and proteins then form the basis for protein quantification of a reference proteome across different instruments. This yields the identification/quantification SOP. (ii) A reference proteome standard material from MAQC IV will be prepared and analysed. a) We will use/recommend our routine LC method as a LC method SOP to measure the MAQC IV reference proteome standard material. Thoroughly analyze the features of the MAQC standard material in different aspects (identification, quantification, protein abundance ranking) and keep evaluating the reproducibility and stability of the protein samples over 1 year. b) We will then dispatch the MAQC IV reference proteome standard material, recommend the LC method SOP and the identification/quantification SOP to different labs for proteome identification/quantification. We will compare the results of the MAQC proteome standard material across different MS instruments in different labs and in different locations (iii) Generate the final MAQC IV SOP and the proteome benchmark dataset for the MAQC proteome standard. Timeline Collect 293T QC experiment data complying with SOP Analyse 293T data and collect experimental data from standard reference material of MAQC with SOP Analyse data from standard reference material and generating proteome benchmark dataset. 52

Project #5: A structured approach to comparing genomics, computational, and high content biology screening methods for predicting toxicity Project coordinators: Shraddha Thakkar (Sharddha.Thakkar@fda.hhs.gov) Weida Tong (Weida.tong@fda.hhs.gov) How to participate: Please contact the coordinators to express your interest to analyze genomics data, in vitro data, and/or in silico data. Objectives: The goal of this project is to benchmark and comparative analysis of three major high throughput methodologies (i.e., genomics, in vitro and computational approaches) for predicting drug induced liver injury (DILI). We will evaluate these methodologies to understand their performance individually and in combination. Background 53

56 Drug induced liver injury (DILI) is one of the primary challenges for drug development as well as regulatory application owing to the poor performance of existing preclinical models. This concern has led to significant efforts on evaluating alternative methods such as computational and genomic methodologies. The adoption of these types of approaches marks a paradigm shift for 21 st century toxicology. Importantly, some have emerged as critical tools in regulatory decision making in the EU under the REACH/3Rs initiative. In the US, both Tox21 and ToxCast have been evaluating these methodologies for regulatory applications. Mathematically, a predictive model is a solution of Y=f(X), where f is a mathematical function used to predict the toxicological endpoint (Y) from input data X. The selection of X (technologies used to generate input data) and f (such as machine learning methods) affects the predictive performance of Y, along with the choice of compounds used in this equation. Many DILI models using these technologies have been described but their performances are difficult to compare due to minimal overlap in the choice of drugs, mathematical functions used (f) and measurement technologies (X). Thus, the true value of these technologies for DILI prediction is poorly understood. This study aims to compare/contrast the three main approaches (genomics, in vitro, and in silico) by systematically assessing the factors important in Y=f(X). Benchmarking data will be generated via a direct comparison of these three to assess their strengths individually and in combination. For the analysis, crowdsourcing approaches will be used via the societies with existing mechanisms. This systematic approach will generate evidence for realistic expectations to assess these technologies for DILI. Furthermore, it will also provide a guidance to analyze readiness and gaps for application of predictive modeling with new data streams in the context of regulatory decision making. Specific Aims: Aim 1: Generation of comprehensive list with DILI annotation We have developed Liver Toxicity Knowledgebase (LTKB) classifying the DILI risk of FDA approved drug. However, we need to extend this list beyond FDA approved drug to capture global DILI landscape of the drugs. We are planning to generate a comprehensive list of drugs with the DILI classification information. This list will be used in all the further mentioned project. Aim 2: Benchmarking Genomic predictive methods for DILI (gdili) Two genomics datasets will be used, cmap and L1000, both produced by Broad Institute. cmap represents the whole genome profiling approach while L1000 data is focused on a biologically relevant small and focused gene sets. Gene expression based DILI predictive models will be generated for each dataset with various machine learning methods (including both supervised and unsupervised approaches). The impact of machine learning approaches and genomics platforms will be evaluated. We will work with Critical Assessment of Massive Data Analysis (CAMDA) for this component of the project. CAMDA has established a community to conduct crowdsourcing projects for the past 12 years. We will distribute the datasets via CAMDA. Aim 3: Benchmarking in silico predictive methods for DILI (isdili) Different computational model (QSAR based or non QSAR based) have been reported to predict human DILI. For this comparison, we will benchmark all the known methods and compare them across various DILI classification schemes. For the past 8 years of developing Liver Toxicity Knowledge Base (project# E ), we have established collaborations with many institutes for in silico DILI modeling. Most of them are listed as external collaborators of this project, including the MAQC Society. We will expand this list for this component. Aim 4: Comparative evaluation of gdili versus isdili Genomics and in silico methods bring two different prospective in DILI prediction. Comparative evaluation of gdili and isdili will help establishing the realistic expectations from each approach individually or in combinations. For this comparison, we will analyze both the training and validation results from both gdili and isdili. 54

57 Study Design We will engage the societies that have experience with an established mechanism to conduct the crowdsourcing project. During the preparation of this project, we have successfully obtained the commitment from two Societies, CAMDA ( and MAQC ( We will generate 5 6 datasets which contains DILI positives and negatives defined by various methods (e.g., based on drug labeling, literature, case reports, or registry). These datasets will divided into a training set (2/3) and a validation set (1/3) by proportionally splitting across different therapeutic categories between training and validation sets. Both training and validation sets will be released to the societies at once with the former having the class labels that will be absent for the validation set. The participants will send the following information to us once the analyses are complete: (1) The analysis protocol, (2) The training set results, such as accuracy, specificity, and sensitivity, and (3) The predicted class label for the validation set. We will analyze all the results to determine the performance of the submitted models. With this study design, we will be able to understand: 1. The performance landscape of both genomics (gdili) and in silico (isdili) methods for human DILI prediction (e.g., upper and lower bound performance). 2. The difference between two methodologies. 3. The fit for purpose application of these two methodologies individually and in combination. Timeline 2 months: Generation of comprehensive list with the DILI classification 3 5 months: Data compilation for the gdili and isdili 5 9 months: data analysis 9 12: comparative meta analysis analysis of gdili with isdili 55
