1:55 Metabolic Biomarkers in Duchenne Muscular Dystrophy

Subha Madhavan, Ph.D., Director, Innovation Center for Biomedical Informatics, Georgetown University Medical Center; Director, Clinical Informatics, Lombardi Comprehensive Cancer Center; Director, Biomedical Informatics, Georgetown-Howard Universities CTSA; Associate Professor, Department of Oncology, Georgetown University

Duchenne Muscular Dystrophy (DMD) is a devastating degenerative X-linked disorder which affects approximately 1 in 5,000 newborn males and results in muscle degeneration, eventual loss of ambulation around the age of 9, and a life expectance of around 25 years of age. We considered serum metabolomic profiling of 51 DMD patients and 22 age-matched healthy volunteers in order to find novel serum circulating metabolites for DMD, with the ultimate goal of discovering molecular surrogate markers associated with disease progression, which can be used in future clinical trials. The DMD patients had a minimum age of 4, a maximum age of 28.7, and a median age of 11.4 years, while the healthy controls had a minimum age of 6, a maximum age of 17.8, and a median age of 13.7 years. 22 of the 51 DMD patients were non-ambulatory at the time of serum collection. As expected, age and ambulation status were strongly correlated in the DMD group, where patients with ages between 4 and 17.8 years, with a median of 6.8 years, were ambulatory, while patients between 11.4 and 28.7 years, with a median of 18 years, had lost ambulation. Liquid chromatography – mass spectrometry (LC-MS) techniques were used to process the serum of the study participants, with the XCMS analysis tool detecting a total of 246 peaks in negative mode and 1676 peaks in positive mode. Metabolite values were further log2 transformed, then normalized using internal standards for both modes. A two-class comparison using a two-sample t-test identified 46 peaks associated with disease status at a false discovery rate (FDR) threshold of 0.05, employing a Benjamini-Hochberg correction. A similar comparison was performed for the DMD cases, comparing ambulatory and non-ambulatory individuals, leading to 154 significant peaks at an FDR threshold of 0.05. After the analyses are finalized, significant peaks will be annotated, in order to match the m/z values to metabolite identities. One particular challenge in interpreting these results is eliminating metabolites which are not associated with disease mechanism from further consideration, such as those associated with drugs or dietary supplements used by certain patients. A bioinformatics platform for metabolic data interpretation has been developed and tested to identify DMD-associated biomarkers and will be made available on GitHub once validation is complete. This platform will be presented along with another use case from a breast cancer metabolomics study.

2:25 Personalized Medicine: Moving from Correlation to Causality in Breast Cancer

Michael Liebman, Ph.D., Managing Director, Strategic Medicine, Inc.

Sabrina Molinaro, Ph.D., Institute for Clinical Physiology, National Research Council, Italy

We have developed a fundamental model of the disease process for breast cancer, from pre-disease through early detection, treatment and outcome, and apply a multi-scalar approach across the risk assessment-enhanced diagnosis-therapeutic decision axis and will present the modeling methodologies.

2:55 Using Big Data Search and Analytics to Find Networks of Experts and Expertise in Complex R&D Environments

Xavier Pornain, Vice President, Sales & Alliances, Sinequa

This presentation will discuss a project in production at AstraZeneca including challenges, dealing with their scientific vocabulary, detecting “synonyms” as well as “similar” and “complementary” notions. Vast quantities (200 to 500 million) of highly technical documents and data need to be analyzed to find enterprise experts on a given topic, as well as related fields, by the “fingerprint” they leave in documents and data.

4:00 Extending Galaxy with External Microbiome Databases

Bob Brown, Ph.D., Affiliate Professor, Environmental Science, George Mason University

Galaxy is a fantastic framework for repeatable multiple tool processing on specific data domains. We have extended Galaxy with a Drupal interface to a MySQL Database of Microbiome datasets. This allows for seamless access of specific subsets of metadata and sequences to be brought into Galaxy for processing.

4:30 A Rigorous Methodology for Non-Randomized & Observational Study in Healthcare Testing

Gil Weigand, Ph.D., Director, Strategic Projects, Oak Ridge National Laboratory

Healthcare R&D or innovation trials have for more than a decade experienced an acceleration of the application of non-randomized study (NRS), including observational or pragmatic methods. Driven by a demand for rapid translation and patient centeredness using a randomized controlled trial—todays acknowledged “gold standard” for testing in healthcare—may not be practical or desirable when there is a need for flexibility, responsiveness, or timeliness. The challenge for researchers and clinicians using NRS testing is getting sufficient rigor in the scientific evaluation to assure data and study veracity, particularly as complexity and heterogeneity increase in innovation trials. IDAMS-HC achieves the state-of-the-art available today with regard to rigor, technology, and science-based in evaluation of NRS and it supersedes today’s ad hoc methodologies. Moreover it increases external validity. In this presentation, we present an advanced rigorous science-based evaluation methodology for evaluation in healthcare testing. The methodology extends today’s general practice, rapid cycle evaluation, by introducing in silico methods of big data and modeling & simulation and tightly integrating the methods within a knowledge discovery infrastructure. An ACO intervention trial provides initial experience with IDAMS-HC.

DATA CAPTURE, ANALYSIS, MODELING & SIMULATION 

10:30 Chairperson’s Remarks

10:40 Structure-Based Algorithms to Predict Drug-Mediated Toxicity

Khaled Barakat, Ph.D., Assistant Professor, Katz Group-Rexall Centre for Pharmacy & Health Research, University of Alberta

This talk presents new insights on how state-of-the-art high performance computing and cutting-edge molecular simulations were used to predict toxicity of candidate drugs. To be biologically active, drugs must physically fit into the binding site(s) within their targets. However, to reach its precise binding location it has to interact with a variety of cellular components with various structures and functions. All these events increase the probability for a drug to bind to undesired off-target(s), which may induce adverse side effects and severe toxicities. During this talk, we will demonstrate how high performance computing combined with conformational sampling, molecular docking and molecular dynamics (MD) simulations were used to build realistic models for these off-targets. We will focus on cardiotoxicity and use our newly developed hERG model as a test case.

11:10 An Informatics Solution for the Precise Registration and Visualization of Biological Molecules

Roxanne Kunz, Ph.D., Senior Scientist, Therapeutic Discovery, Amgen, Inc.

A custom bioinformatics software application for the registration and representation of biological molecules will be described. The system includes a flexible, modality-independent editor to define biomolecules in a step-wise fashion, backed by a chemical structure-based database catalog to precisely capture atomic-level modifications of amino acids and other non-proteinaceous components. Data-driven visual representations based on canonical biological molecule structure reference types, such as IgG1 monoclonal antibodies and subtypes thereof, are dynamically constructed and interactive.

2:00 Using Deep Learning Techniques for Word Vectors Generation for Insight into Poorly Structured Textual Data

Mark Pinches, Senior Scientist, Data Modeling and Bioinformatics, Drug Safety and Metabolism, AstraZeneca

Word vectors carry a number of interesting properties that can be applied to textual data in order to cluster/stratify data for additional analysis. This emerging approach has been used in other fields but here we apply it to biological data. This presentation illustrates a concrete example of this technique with clear and unique outcomes.

2:30 Examining the Health Effects of Multiple Environmental Exposures on Subpopulations Using a Big Data Platform

Chirag Patel, Ph.D., Research Associate, Center for Biomedical Informatics, Harvard Medical School/Pivotal, Inc.

The environment plays a large role in human health, but we lack computational tools to unlock the relationship between exposure and disease. For example, most studies examine the effects of single environmental agents and ignore the complex interplay of an individual’s characteristics and comorbidities. This offers an unrealistic view of the human experience. With the availability of scalable platforms, we are now able to ask many more questions to examine more complex relationships between environmental exposure and disease. In this talk we will present our results from examining the complex interdependencies between 1000s of environmental agents (e.g., infectious agents, biomarkers of pollutants, and nutrient exposure) in datasets representative of the US population. Specifically, we consider over 100K individual pairwise correlations between exposures and quantitative health-related traits in different segments of the US population, a computationally burdensome task but critical toward a "human exposome project".

3:00 Streamlined Planning, Execution, Data Capture and Analysis of Peptide Preformulation Stability Studies

Roman Affentranger, Dr. sc. Nat, Head, Small Molecule Discovery Workflows, Roche

The presentation will illustrate what we have implemented for the peptide preformulation scientists in their electronic lab notebook to efficiently design peptide formulation stability studies. The study can cover a number of different formulations, and with the definition of time points, stress conditions and desired analytical methods the required number of vials as well as individual material amounts are automatically calculated. Individual analytical results are captured through predesigned templates that are specific for the different types or analytics, and the results are linked to the stability study by a unique study ID. All along the study execution, as well as for the completed study, all the data - formulation composition, study design and all analytical results - are pulled together in a data analysis tool, also within the electronic lab notebook. The data analysis tool allows selection of individual or multiple formulations, time points, and stress points, and therefore offers unique insights which greatly support decision making for improved formulation design.

3:30 Welcome to the Future: Data Analysis in a Language Workbench

Fabien Campagne, Ph.D., Assistant Professor and Laboratory Head, Institute for Computational Biomedicine, Weill Cornell Medical College

We have devised an analysis tool (http://workbench.campagnelab.org) that takes advantage of Language Workbench (LW) technology and in particular of the open-source Meta Programming System. Using this technology, we created languages for biological data analysis that do not require a strong computational background, which can be used by most biomedical researchers, yet that scale to large datasets. These languages provide high-level abstractions such as organisms, filesets, execution nodes, analysis plugin, or analysis tasks that model the biological data and the computational environment in simple ways. End-users interacting with the workbench can configure analyses that will execute on parallel computers without these users knowing about parallel computing, programming, scripting languages or the command line. The talk will highlight how both end-users and tool designers can benefit from this technology.
