Personalized medicine is based on the analysis of inter-patient differences at the molecular level through the measurement of biomarkers. Biomarkers are detected in human biospecimens that represent samples for particular molecular tests. A systematic approach is necessary for quality assessment of biospecimens as well as for their appropriate pre-analytical processing both in research and in clinical laboratory. Novel genomic sample preparation technologies have the ability to significantly increase sensitivity and specificity of a test that is run on a heterogeneous sample or a sample that contains a low concentration of analyte. Cambridge Healthtech Institute’s Second Annual Genomic Sample Prep and Biospecimen Science conference is designed to bring together leading industry and academia experts in biospecimen science and molecular diagnostics to discuss major challenges and latest advances in sample preparation for advanced genomic technologies as well as biospecimen management and quality assurance.

2:10 Validation Challenges for Panels and Exomes
Josh Deignan, Ph.D., Associate Director, UCLA Molecular Diagnostics Laboratories, Department of Pathology and Laboratory Medicine, David Geffen School of Medicine, UCLA
Guidelines for the validation of molecular diagnostic tests have existed for some time, but guidelines for NGS testing have only recently emerged. Moreover, the approach required for the validation of a NGS mutation panel is different than the one required for an exome sequencing test, both of which are now offered clinically at UCLA. This talk will discuss our experiences with the validations of these two types of NGS tests.
2:40 FDA-Approved Versus LDT-Based NGS Systems: Preanalytical Issues and Validation
Jamie L Platt, Ph.D., Vice President, Genomic Solutions, Molecular Pathology Laboratory Network, Inc.
As NGS technologies have matured and their utility in clinical diagnostics has been embraced, the evolution of RUO-based Laboratory Developed Processes (LDPs) to FDA-Cleared In Vitro Diagnostic Tests has followed. The major considerations around Preanalytical issues for these two categories of systems will be compared and discussed. In addition, the key validation or verification challenges will be contrasted and discussed within the context of a CLIA Lab experience using both types of systems. The objective of the presentation is to provide sufficient information, drawn from experience, to enable labs to choose the path that best suits their environment, goals and objectives.
3:10 PANEL DISCUSSION: Comparing Major NGS Instruments: Technical Differences, Application Preferences
Moderator: Jamie L Platt, Ph.D., Vice President, Genomic Solutions, Molecular Pathology Laboratory Network, Inc.
Selecting the NGS platform or platforms that best address the pre-analytical and technical considerations of the assay objectives given the specific environment can be a challenging undertaking. Platform throughput, chemistry, and error modality vary greatly and are tightly tied to overall assay performance. This discussion will focus on the strengths and capabilities of the different commercially available NGS platforms from the perspective of users with experience on multiple platforms.

10:45 Preparing Research Samples for Future Use: Innovative Methods for Assessing Functional Quality Control and Biobanking Best Practices
Andrew Brooks, Ph.D.,COO and Director,Technology Development, Technology, RUCDR Infinite
Variable DNA sample quality and the lack of standardized sample tracking in biorepositories perpetuates sample ID errors caused by mishandling during sample collection, storage or use. The RUCDR finds that greater than 98 percent of biorepository errors occur from issues during sample collection and are not errors in sample processing once they arrive at the biorepository. Sample qualification and verification prevents erroneous use of misidentified samples in downstream experiments and also ensures high-quality data from samples being analyzed.
11:15 Practical Approaches to Expanding Biorepository Representation: Innovative Tissue Print Technologies for Collecting High Quality Snap-Frozen Specimens for Biomarker Research
Sandra M. Gaston, Ph.D., Director, Molecular Biomarkers Research Laboratory,Pathology and Laboratory Medicine, Tufts Medical Center Assistant Professor of Pathology, Tufts University School of Medicine
Most human tissue samples obtained from clinical biopsy and surgical resections are only secondarily considered as research specimens, and any plan to collect tissue for research must put first priority on patient care. Remnant tissues obtained from fresh surgical specimens are the mainstay for biorepositories that provide high quality snap-frozen samples for research, but many critical areas of a surgical resection and most diagnostic biopsies cannot be easily “divvied up” before the tissue is submitted for processing as a formalin-fixed paraffin embedded (FFPE) specimen.

1:50 Circulating RNA - Is it a Blessing or a Curse?
Kai Wang, Ph.D., Principle Scientists, Institute of Systems Biology
Cell free circulating RNA has attracted a great deal of attention in recent years as specific physiopathological conditions have been linked to varying concentrations of various RNA species. However, there are a number of challenges in accurately assessing levels of specific circulating RNA sequence. Standardized sample preparation protocols and new measurement approaches are clearly needed. In the meantime caution should be exercised when interpreting circulating RNA based results.
2:20 Human Cerebrospinal Fluid (CSF) miRNA Analysis: Critical Factors in Sampling Preparation and Detection
Wang-Xia Wang, Ph.D., Senior Scientist, Sanders-Brown Center on Aging, University of Kentucky
Human cerebrospinal fluid (CSF) microRNAs (miRNAs) have been proposed as potential biomarkers for disease conditions, specially, neurodegenerative diseases; however, technical challenges related to RNA sample preparation and detection has hindered the establishment of reproducible miRNA signatures. This talk will focus on the overview of technical aspects of CSF RNA sample preparation and detection, and will discuss the recent advance including several commercially developed extracellular miRNA/RNA sample preparation and analysis platforms..
2:50 RNAssist Fixative and Stabilizer for Immunohistochemistry and the Recovery of High Quality RNA, DNA and Proteins
Andrew Goldsborough, Ph.D., CEO, RNA Stability, RNAssist Ltd
The RNAssist reagent has been developed to efficiently fix tissue samples whilst preserving RNA, DNA, proteins as well as tissue histology for IHC analysis. It does not contain alcohol or formaldehyde, has very low volatility and is biodegradable. RNA stabilisation is superior to both standard fixatives and dedicated RNA stabilisation solutions. Results will be shown demonstrating RNA, DNA and protein stabilisation, and IHC in RNAssist fixed tissues.
3:20 Extending The Reach Of Molecular Diagnostics: Sample-To-Result Infectious Disease Tests
Barry Lutz, Ph.D., Research Assistant Professor, Department of Bioengineering, University of Washington
We are developing tests for DNA and RNA that can be performed outside conventional laboratory settings. All steps from sample preparation to visual readout are carried out automatically without an instrument. Data collection by a cell phone will allow transmission of results to a healthcare provider and medical record. Project goals include commercializable tests as well as broad platform capabilities for future tests. We are also collaborating to develop simplified drug resistance tests based on detection of single-base mutations in HIV and other infectious diseases.

4:10 Isolation of DNA/RNA Biomarkers and the Quest for Liquid Biopsy Cancer Diagnostics
Michael J. Heller, Ph.D., Professor, Nanoengineering & Bioengineering, University of California San Diego
The isolation of circulating cell free (ccf) DNA and ccf-RNA directly from blood and/or plasma remains a complex and time consuming procedure, which is impeding process toward liquid biopsy and point of care (POC) cancer diagnostics. We have now demonstrated the rapid isolation and detection of ccf-DNA/RNA from a number of different hematological and solid tumor samples.
4:40 Antibody Validation to Prevent Error
David L. Rimm, M.D., Ph.D., Professor, Pathology; Executive Director, Translational Pathology; Director, Yale Pathology Tissue Services, Yale University
Antibodies are an extremely broadly used and valuable tool, both in discovery research, translational research and in the clinic. However, some of the data produced and published in the literature is flawed, or misleading due to non-specificity or cross-reactivity. Here we will look at the use of antibodies, both in the research and clinical setting and show how lack of rigorous validation can produce flawed data. We will also provide guidelines for antibody validation that can be used to avoid flawed, but publishable results.
5:10 Managing Quality in Biorepository Operations to Support Translational Research- Experiences of the OHSU Knight BioLibrary
Devon Kelly, Director, OHSU Knight BioLibrary, Knight Cancer Institute, Oregon Health and Science University
Methods by which human research specimens are consented, collected, stored and distributed varies greatly from repository to repository. This variation is a large contributing factor in the ability of researchers to generate high-quality data from specimens acquired from multiple repositories into a single research project. Therefore, it is important to manage the quality of biobanking activities to maximize the utility of banked specimens collected for future research projects. Experiences in assessing and standardizing practices across a large cancer repository network will be discussed.
