Clinical NGS Diagnostics

Translating Genomic Data to the Standard of Care

February 20-22, 2017 | Moscone North Convention Center | San Francisco, CA
Part of the 24th International Molecular Medicine Tri-Conference

 

Clinical sequencing is paving the way for the application of molecular diagnostics in infectious disease, newborn medicine, cancer, autoimmune, genetic and immunotherapy. Many of these applications were formerly intractable, requiring an odyssey of trial and error over weeks or months and at great expense. Now a myriad of tools is being used to enable accurate and rapid diagnosis and is allowing new treatments. The Clinical NGS Diagnostics track will feature novel technologies available for clinical use along with validation, implementation and standardization protocols for sequencing.

IMMUNOSEQUENCING AND CANCER MEDICINE

2:30 Chairperson’s Remarks

German Pihan, M.D., Director, Hematopathology Lab, Pathology, Beth Israel Deaconess Medical Center and Harvard Medical School

2:40 Profiling of Exhausted T Cells in Tumors Predicts PD-1 Response

Kelly Mahuron, M.D., Resident, School of Medicine, University of California, San Francisco 

Immune checkpoint blockade is revolutionizing therapy for advanced cancer. However, many patients do not respond to treatment. The identification of robust biomarkers that predict clinical response to specific checkpoint inhibitors is critical in order to stratify patients and to rationally select combinations in the context of an expanding array of therapeutic options. We performed multi-parameter flow cytometry on freshly isolated metastatic melanoma samples prior to treatment and correlated subsequent clinical response with tumor immune phenotype.

3:10 Defining Immunoglobulin Somatic Hypermutation in de novo Diffuse Large B-Cell Lymphoma Patients: Potential Application for Prognosis and Risk Stratification

Ken H. Young, M.D., Ph.D., Professor, Hematopathology, The University of Texas MD Anderson Cancer Center

Characterization of immunoglobulin gene helps to identify cell-of-origin of mature B cell malignancies such as chronic lymphocytic leukemia, whereas its role in the pathogenesis of DLBCL is poorly understood. In this study, we studied molecular repertoire of both immunoglobulin heavy- and light-chain genes in a large cohort of de novo DLBCL patients using high-throughput next generation sequencing (NGS).

3:40 High-Throughput TCR Sequencing Provides Added Value in the Diagnosis of Cutaneous T-Cell Lymphoma

Thomas S. Kupper, M.D., Chair, Dermatology, Brigham and Women’s Hospital; Dana Farber Cancer Institute; Thomas B. Fitzpatrick Professor, Harvard Medical School

Cutaneous T Cell Lymphomas (CTCL) are the most common extranodal non-Hodgkins T cell lymphomas. The diagnosis can be difficult and delayed (avg 5-6 years), as the lesions resemble inflammatory skin disorders. Unlike PCR-based clonality assays, high throughput sequencing of the TCR genes yielded a 100% sensitivity for detection of a clonal T cell population in CTCL lesions. HTS can also be used to assess response to therapy.

2:10 Choosing an Effective Validation Plan for NGS Assays in Oncology

Helen Fernandes, Ph.D., Director, Molecular Pathology, Pathology & Laboratory Medicine, Weill Cornell Medical College

The analytical validation of an NGS assay for the most part determines the reliability of results and therefore dictates the effectiveness of the assay for management of the cancer. As the number of laboratories offering NGS tests in oncology increases, the need for recommendations and guidelines that address the processes of assay validation are noteworthy. Several organizations and regulatory bodies have been working on developing documents to help and guide laboratories plan and execute the validation of NGS assays for oncology. In this presentation, we will discuss the validation prerequisites that are important and need to be addressed for implementing a reliable and useful NGS assay for oncology.

2:40 Towards Implementation of NGS as Clinical Assay: FFPE Pre-Analytical Optimization and Analytical Consideration in WES Commercial Lab Selection

Ping Qiu, Ph.D., Translational Molecular Biomarkers (TMB), Genomics, Merck Research Laboratories

Higher non-synonymous mutational burden assessed by whole exome sequencing in tumors is associated with durable clinical benefit in immune checkpoint inhibitors treatment. Cancer genome WES poses a unique challenge due to limited tissue, tumor heterogeneity and sequencing artifacts introduced by FFPE tissue. Multiple genomics CROs were assessed on their NGS pre-analytics and the quality of WES data generated. Recommendations are made on FFPE WES pre-analytics and data interpretation.

3:10 Genotyping in an HTP Drug Development Pipeline: Tough Assays, High Sample Numbers, and Ever-Changing Goals

J. Colin Cox, Ph.D., Science Manager, Genentech

Deborah Siler, Ph.D., Senior Research Associate, Mouse Genetics, Genetech

We use “acoustic droplet ejection” (ADE) to perform high-throughput genotyping in the context of an R&D biotherapeutics pipeline. Our lab processes roughly 350,000 samples a year in order to generate ~800,000 genotypes on very complex genetic models. Recently, we validated a no-downtime upgrade from traditional pipetting robots to ADE dispensers and investigated the effect on cross-contamination and return-on-investment.

11:00 Genomic Sequencing of Healthy and Sick Newborns in the BabySeq Project

Joel Krier, M.D., MMSc, Clinical Chief, Division of Genetics; Director, Brigham Genomic Medicine, Brigham and Women’s Hospital; Instructor, Harvard Medical School

The BabySeq Project is a proof-of-concept randomized control trial examining the implications of genomic newborn sequencing (gNBS) in two populations: a) sick or premature neonates admitted to the Boston Children’s Hospital and Brigham and Women’s Hospital (BWH) ICUs and b) generally healthy neonates from the BWH well nursery. This presentation will summarize the key progress and findings to date including study design, implementation, and preliminary results.

11:30 Ethical and Social Challenges Associated with Sequencing Newborns

Don Bailey, Ph.D., Distinguished Fellow, RTI International

Next-generation sequencing offers the promise of potentially useful health information but also evokes a number of ethical and social challenges. I describe a few of the major concerns, summarize what is known about each, and suggest strategies by which each could be mitigated.

12:00 pm Exome Sequencing of Newborn Dried Blood Spots: Implications for Newborn Screening and for Exome Diagnostics

Steven E. Brenner, Ph.D., Professor, Plant & Microbial Biology, University of California, Berkeley

Public health newborn screening (NBS) identifies newborns with rare treatable conditions, permitting early intervention. The NBSeq project is evaluating the potential of whole exome sequencing in NBS using de-identified, archived dried blood spots (DBS) under an IRB-approved protocol with the California Department of Public Health. One aim explores feasibility of WES to replace or augment MS/MS for metabolic disorders. DBS of all California newborns from Jul 2005–Dec 2013 with disorders diagnosed by MS/MS and a selection of false positives were made available (1600 samples) and are being studied.

EMERGING BIOMARKERS PREDICTING RESPONSE TO IMMUNOTHERAPY

1:50 Chairperson’s Remarks

Luis A. Diaz, M.D., Head, Solid Tumor Oncology, Memorial Sloan Kettering Cancer Center

2:00 Genomic Features of Resistance to Anti-PD-1 Immunotherapy

Jesse Zaretsky, UCLA-Caltech Medical Scientist Training Program, Department of Molecular and Medical Pharmacology, David Geffen School of Medicine, University of California, Los Angeles

Resistance to anti-PD1 immunotherapy can take the form of either innate lack of response, or late acquired resistance after initial tumor regression. For the former, we define a transcriptomic mesenchymal and wound-healing associated expression signature enriched among non-responders in pre-therapy tumors from metastatic melanoma patients. For the latter, exome sequencing of paired pre/post relapse tumors revealed loss of function mutations in the interferon response pathway and antigen presentation machinery.

2:30 Shaping of Immunotherapy Response by Cancer Genomes

Rajarsi Mandal, M.D., Head & Neck Surgical Oncology Fellow; Professor, Surgery, Memorial Sloan Kettering Cancer 

Immune checkpoint blockade is a promising approach for the treatment of human malignancies. For example, treatment of patients with advanced lung cancers and melanoma have resulted in improved response rates and durable disease control. However, the extent to which patients derive benefit is diverse and the determinants that drive response to therapy are ill-defined. We have sought to define the genomic determinants of response to immune checkpoint blockade therapies such as anti-CTLA-4 and anti-PD-1. Our work has shown that tumor mutational burden, clonality, and mutational landscape features help dictate clinical response. Mutations in genes that are part of the antigen presentation machinery are rare but can be preferentially downregulated in tumors. Reexpression of genes in the MHC antigen presentation pathway by treatment with epigenetic therapy synergizes with immune checkpoint blockade to boost anti-tumor responses.

3:00 Addressing the Challenges Associated with Immuno-Therapy Biomarker Testing

John Leite, Ph.D., Vice President, Oncology, Market Development & Product Marketing, Illumina, Inc.

Recent developments in immuno-therapy have yielded exciting and promising results, but have also highlighted the need for effective predictive solutions. In this session, we will discuss the inherent testing challenges facing translational researchers, and future challenges facing clinicians seeking to implement these solutions into routine clinical practice.

GENETIC CHARACTERIZATION OF PATIENT TUMORS AND CTCs

3:40 Chairperson’s Remarks

Stuart S. Martin, Ph.D., Associate Professor, Physiology, Greenebaum NCI Cancer Center, University of Maryland School of Medicine

3:45 Scalable Approach for Whole-Exome Sequencing of Cell-Free DNA from Patients with Metastatic Cancer

Viktor Adalsteinsson, Ph.D., Group Leader, Broad Institute of MIT and Harvard

Whole-exome sequencing of cell-free DNA (cfDNA) may enable comprehensive profiling of tumors from blood. Here, we describe a scalable approach to qualify and sequence whole-exomes of cfDNA. Whole-exome sequencing of cfDNA and biopsies from 23 patients revealed high concordance of clonal somatic mutations (90%), copy number alterations (80%), mutational signatures, and neoantigens. Screening of 879 blood samples from 333 metastatic cancer patients revealed 42% with sufficient tumor content for whole-exome sequencing.

4:15 Simultaneous Detection of Living Circulating Tumor Cells and Cancer Related Extracellular Vesicles in Blood by a Molecular Beacon Based Biochip

L. James Lee, Ph.D., Professor, Chemical and Biomolecular Engineering, The Ohio State University

A novel and facile immune-lipoplex nanoparticle (ILN) biochip is developed to simultaneously capture and characterize living circulating tumor cells (CTCs) and cancer related extracellular vesicles (EVs) in patient blood. Antibodies are used to capture CTCs and EVs in a microfluidic device, while molecular beacons encapsulated in cationic lipoplex nanoparticles and fluorescence labelled antibodies are used to detect coding and non-coding RNA targets and membrane protein targets respectively in both CTCs and EVs. The identified CTCs are alive for further interrogation such as drug resistance.
