Pre-requisites

There will be some handouts and software installation before the meeting but no pre-req classes.

Overview

Does Excel lag on you when you open a file bigger than 1000 rows? Has it ever changed your data to a date against your will? Are you ready to jump right past Tableau and into the world of Data Science using a real programming language?

Well, your wait is over because at MSACL we again will be offering a course for complete programming newbies that will help you get going analyzing real data related to LC-MS/MS assay development, validation, implementation and publication.

The only background expected is the ability to use a spreadsheet program. The skills that you will acquire will allow you to take advantage of the many tools already available in the R language and thereafter, when you see that your spreadsheet program does not have the capabilities to do what you need, you will no longer have to burst into tears.

The course will be run over two days and time will be evenly split between didactic sessions and hands-on problem solving with real data sets. Drs Bunch & Spies will adopt a “no student left behind policy”. Students will be given ample time to solve mini problems taken from real-life laboratory work and focused on common laboratory tasks. All attendees will need to bring a laptop with the R language installed RStudio interface installed. Students may use Windows, Mac OSX or Linux environments. Both R and RStudio are free and open-source. No cash required.

Students should be prepared for learning what computer programming is really like. This may involve some personal frustration, but it will be worth it.

Overview

The classic dried blood spot (Guthrie Spot, NBS spot) has been used routinely for 60 years in inborn errors of metabolism (rare disease screening of newborns) space in addition to health monitoring of the detected disorders. Mass spectrometry advanced this space 30 years ago to take advantage of its multianalyte profiles (the early days of metabolomics) to detect rare diseases. It was the introduction of multiple biomarkers in clinical assessment. As mass spec evolved in this space, new workflows and pre-analytical methods, sample preparation chemistry was altered by taking advantage of the dried microsample format and extraction chemistry. DBS offered a replacement to liquid microsamples, and the risks and costs associated with infectious disease exposure, cost of shipping using the cold chain, storage and most recently patient centered sampling where remote, or home sampling is made possible.

Most chemistry workflows are still dominated by liquid blood or plasma and immunoassay platforms, they are not necessarily suitable for microsample collection as demonstrated in the choice for newborn screening (200-300 µL) versus 1-10 mL for a venous blood draw. Furthermore, a dried microsample offers better improved stability for some molecules due to degradation of active enzyme, light or heat. Beyond newborn screening standard, the pace of adoption of dried blood versus liquid plasma is slowed because of the lack of bridging studies. Therefore, an understanding of DBS versus liquid is critical in designing these experiments. This course will describe the advantages of filter paper for mass spec workflows in areas of sample cleanup, extraction, manipulation as well as examples of successful analysis. We will provide examples of existing methods in use in clinical analysis and will expand upon last year’s MSACL course.

As important are its advantages, we will discuss limitations from the lack of precision of classic Guthrie cards because of volume uncertainties to the problems of some mass spectrometry analysis of molecules like proteins. Finally, we will correlate these issues with the ever-expanding area of metabolomics, lipidomic and more important how a DBS can be integrated with other technique like molecular and immunoassays to provide a better clinical result from which the clinician can make earlier accurate diagnosis. Ultimate DBS can improve health care services as well as access with remote collection.

Objectives

At the conclusion of this short course, the participant will be able to:

  1. Describe the best fit for DBS utilization in clinical mass spectrometry and bioanalytical research including “omics” applications.
  2. Discuss bridge strategies for adopting existing MS methods that utilize venous blood, plasma or other liquids to the dried microsample format.
  3. Compare the advances in the quantitative micro sampling space and discuss issues with volume and solid matrix additives.
  4. Interpretate approaches for multiplexed analysis and multi-omics.

Pre-requisites

A background in quantitative proteomics is helpful but not required. You will need to know the principles of LC and QQQ analysis through multiple reaction monitoring.

Overview

Download Full Syllabus Here

Did you know proteins may exist in hundreds of molecular proteoforms? And that each specific proteoform may have different functionality, potentially leading to a pathophysiological clinical phenotype ? How could we measure such proteoforms using mass spectrometry? And how could measurement of proteoforms aid in precision diagnostics?

In this course, we will explain what proteoforms are, and why they may be relevant to measure in a medical laboratory. We will use real-lab examples of proteoforms known to affect the patients’ health status and guide you through the potential methods on identifying and characterizing proteoforms with multiple-reaction-monitoring MS. We will start the course with the rationale on when and how to develop new diagnostic tests. We will explain the diversity in proteoforms, with a focus on proteoforms caused by mutations, but we will also touch upon PTM-induced proteoforms. Lastly, we will discuss several quality related aspects of these tests. In the end, our aim is to provide the knowledge necessary to apply proteoform analysis by MS in your own (clinical) laboratory.

The course will consist of theoretical background, examples of applications and interactive sessions. A background in quantitative proteomics is helpful but not required. You will need to know the principles of LC and QQQ analysis through multiple reaction monitoring. At the end of the course, you will know why molecular protein analysis could be beneficial and how you can apply it in your laboratory.

Objectives

At the conclusion of this short course, the participant will be able to:

  1. Discuss what proteoforms are and why they may be relevant to quantify.
  2. Discuss how the analysis of proteoforms will contribute to precision diagnostics and how clinical care pathways may be altered based on molecular protein measurements.
  3. Discriminate proteoforms using multiple-reaction-monitoring mass spectrometry.
  4. Evaluate molecular MS data and provide answers for laboratory specialists
  5. Ensure performance and quality of proteoform-based tests.

Pre-requisites

Knowledge on basic mass spectrometry and spectral interpretation.

Overview

Did you ever encounter glycans, but you -kind of- neglected them as they seemed too complicated to characterize? Or did you just perform a glycan release to make the analysis of your protein a lot easier? You have no idea how to interpret your data when a glycan is present? Fear no more! We are here to provide you with the basics in the field of mass spectrometric glycomics and glycoproteomics.

The course will start with a historical overview on glycan research (i.e. how did glycans work their way up to being acknowledged as important study objects) and we will guide you through the maze of different nomenclatures. Moreover, although glycans are well known for their complexity, we will reveal to you the “rules of glycan structures” based on known biosynthetic pathways. This will be followed by an in-depth discussion on glyco(proteo)mic mass spectrometric technologies and workflows. In addition, different sample preparation steps and data analysis approaches will be covered. We will close-up with a session about glycomic biomarker discovery.

The course will run over two days and time will be split between lectures and workshops (e.g. how do you recognize a glycan in a mass spectrum and how do you assign it). While not everything can be covered within these two days we will ensure that you will know your “glyco-basics” in the end. Moreover, participants are encouraged to submit any specific glyco-questions they have prior to the course and we will try to discuss them during the course.

Objectives:

At the conclusion of this short course, the participant will be able to:

  1. Discuss glycan nomenclature and biosynthesis
  2. Select an appropriate analytical method for a specific glycomics research question.
  3. Interpret mass spectrometry data using the biological background of a sample and the biosynthetic restrictions of the system.
  4. Define the identity of released glycan and glycopeptide molecules using MS1 and MS2 data.
  5. Select the appropriate software tools to aid glyco(proteo)mics MS data processing knowing the used analytical platforms.

Pre-requisites

An introductory R course (including MSACL Data Science 101) and/or experience using R for data analysis.

Overview

Do you have data files that you would like to accumulate over time into an organized, accessible format and then visualize different aspects of the combined data in an interactive, web-based dashboard?

If so, this course is for you!

Reproducibility is an important principle for making data analysis trustworthy and reliable. Automation enables users to scale their data analysis steps. The R programming language is one of many tools that can help users automate data analysis workflows while adopting best practices in reproducibility, but there are several packages to choose from when developing these skills.

In this short course we will introduce a combination of workflows, packages, and tools that help learners set up data analysis projects, develop pipelines for extracting and storing data, and then develop interactive visualizations to gain understanding from the data.

First, we will orient learners to reproducible document formats such as R Markdown and Quarto, emphasizing how data analyses can be communicated effectively.

Next, we will do a crash course on relational databases such as SQLite, which can be powerful tools for storing and accessing data at scale.

We will then tie together concepts in iteration and automation to develop the basics needed to set up a data ingestion pipeline.

In the last portion of the course, we align these concepts with interactive visualization tools to develop an automated dashboard.

This short course will be interactive, with frequent short exercises to reinforce new concepts. Familiarity with the R programming language, either from an introductory course or self-learning, is required to participate in the exercises.

Finally, concepts in this short course overlap material taught in previous intermediate R courses at MSACL, but here we will focus putting together the tools to develop reproducible, automated dashboards for visualization of laboratory data and provide updates to include some of the latest developments in the R ecosystem.

Pre-requisites

Basic understanding of the field of metabolomics and LC-MS.

Overview

Metabolomics refers to the comprehensive measurement of small molecules in biofluids by either mass spectrometry (MS) or nuclear magnetic resonance (NMR) with the aim of covering multiple KEGG pathways, exposome products, and chemical reactions to provide new insights into disease etiologies. MS based metabolomics generally requires the use of liquid chromatography to separate metabolites based on polarity and high-resolution MS to accurately measure the mass-to-charge (m/z). The combination of retention time and m/z accuracy provides a reliable method to identify metabolites, which is critical for making disease marker discoveries. Understanding how data is generated is key to understand how to process data. This short course will instruct attendees on bioinformatics components to data processing in metabolomics with hands on instruction using an open source software package. This short course will also discuss basic principles of statistical analysis with hands experiences provided.

Workshop : Concepts in Histology and Histopathologic Diagnosis for Researchers
@ De Anza 1 (Portola Hotel > Ground Floor)

Albert Tsai, MD, PhD
Stanford


How pathologists diagnose human tissue samples differs markedly from how many researchers study them. Research approaches often seek to reduce two-dimensional tissue imaging to single cell data, i.e. cytometry-on-a-slide. However, these methods are complicated by technical aspects of tissue processing, and they may miss the overarching histologic patterns which underlie pathologic diagnosis. Thus, early engagement with pathologists is useful not only for obtaining tissue samples, but also for understanding structure-function relationships and relevance to disease. Furthermore, pathologists regularly integrate multiple data modalities to classify diseases, e.g. histology with antibody-based protein detection and DNA sequencing. Their understanding of the utilities of each modality within the larger diagnostic context is helpful for identifying potential roles for new technologies.

Get-the-Basics : MALDI Mass Spectrometry Imaging – A New Method in Pathology?
@ De Anza 1 (Portola Hotel > Ground Floor)

Kristina Schwamborn, MD, PhD
Technical University of Munich


Matrix assisted laser desorption ionization (MALDI) mass spectrometry imaging (MSI) combines the excellence in molecular characterization of mass spectrometry with microscopic imaging capabilities of stained tissue samples, enabling the precise location of different analyte classes (e.g., proteins, peptides, lipids, glycans) directly within intact tissue. In particular in the field of pathology, that can aid in tumor diagnosis, tumor subtyping, biomarker identification, prognostic prediction, and characterization of tumor margins during tumor resection procedures. Since MALDI MSI goes far beyond microscopy, it is ideal for these endeavors. It can generate molecular maps of tissue sections that can elucidate the underlying biochemistry or provide information on how therapeutics or toxins influence the function or misfunction of an organ. Thus, it has the potential to overcome limitations of other approaches in the identification and routine diagnostic measurement of new marker molecules/profiles.

Different applications in the field of pathology/ oncology will be presented that highlight possible applications of MALDI MSI in Pathology. Combining MALDI MSI, histology, and statistical analysis allows for reliable and fast subtyping in a number of different tumor types while also conserving material that could be used for additional testing.

University of Iceland

Finnur Eiriksson, PhD
ArticMass


Objectives

The objective of the workshop is to provide an introduction into design of experiments (DoE) for clinical application with special focus on optimization of MS-based clinical assays. The workshop is focused on practical implementation of DoE and will demonstrate how method development of sample preparation and UPLC-MS/MS method for quantification of clinical biomarkers can become much more efficient by utilizing DoE.

Summary

Design of experiments (DoE) is an efficient tool for development and optimization of UPLC-MS/MS platform for quantification of biomarkers in complex biological matrices. The UPLC-MS/MS platform is composed of several processes which involve many experimental factors that need to be simultaneously optimized to obtain a true maximum sensitivity with adequate resolution at minimum retention time. DoE offers a practical approach for performing experiments in accordance with a predefined plan, modelling by empirical functions, and graphical visualization. Basic concept of DoE will be presented with emphasis on practical implementation of DoE which includes the three main stages, screening, optimization, and robustness testing. To demonstrate the benefit of DoE, two case studies will be presented. The first case is DoE optimization of sample preparation in bottom-up targeted protein workflow. The second case is DoE optimization of UPLC-MS/MS assay for clinical diagnostic and therapeutic drug monitoring of patients with adenine phosphoribosyltransferase (APRT) deficiency. A polynomial model which corresponds to the objective of the case study is specified and an experimental design that supports the selected model is generated. Significant factors were studied via central composite design and related to responses utilizing partial least square regression. Both cases showed that DoE is an excellent tool for optimization of sample preparation for biological samples and UPLC- MS/MS quantification method for clinical biomarkers. A significant reduction of sample preparation time was achieved with increased yields for selected peptides and a reliable UPLC-MS/MS assay for simultaneous quantification of urinary 2,8-dihydroxyadenine (DHA) and adenine was optimized efficiently with DoE.

• Design of Experiments (DoE) – Get it right from the beginning
• Basic concept and assessment of DoE
• Optimization of sample preparation and UPLC-MS/MS clinical assay by DoE

Workshop : Study Design for Metabolomics
@ Steinbeck 2 (Conference Ctr > 2nd Floor)

Jerzy Adamski, PhD
Metaron Diagnostics i.G., Technical University of Munich


CANCELLED : Due to the presenter being unable to attend (March 2, 2024).

Objective

This workshop will address study design challenges for metabolomics that must be performed prior to metabolomics measurement and data processing.

Summary

The workflow of a metabolomics experiment follows several interdependent phases. The scientific question determines the study model and the type of metabolite detection. Pilot studies are often performed to validate the research question and the analytical approach chosen. Sample identity, preanalytics, sample matrix, confounders, timing, randomization, budgeting and resources, contingency plan, legal issues, governance, and replication are important considerations in the study design phase. Metabolomics requires special quality control and quality assurance procedures because of the many variables involved in sample preparation and analysis. Analytical procedures include quality assurance, matrix-matched reference samples, and analytical quality control. Data validation is performed to verify technical parameters, evaluate sample quality, and identify outliers. In the initial phase of a project, it is critical to define the dataset to be released, which must include metabolomics data, SOPs, assays used, randomization type, normalization structure, and data imputation protocols.

Specific Topics

• understanding cohort structure
• essential clinical phenotyping
• procedures for sample selection
• sample quality assessment
• analytical assay selection
• randomization for measurements
• requirements for preparation for metadata and data depositories
• GOFAIR initiative for sustainable research

Christopher Chouinard, PhD
Clemson University

Robin Kemperman, PhD
Children’s Hospital of Philadelphia


Objectives

Attendees will learn the basic principles of ion mobility, benefits and challenges to routine implementation in the clinical lab, method development, and current applications.

Objective 1: Understand the basic operating principles of IMS and the differences between the different techniques (e.g., drift tube, traveling wave, FAIMS/DMS, etc.)

Objective 2: Recognize the benefits and limitations to incorporating IMS into conventional LC-MS/MS workflows in the clinic.

Objective 3: Become familiar with method design and development and current/future applications.

Summary

Ion mobility-mass spectrometry (IM-MS) has become a cornerstone of biomedical analysis, with applications ranging from isomeric small molecule differentiation to the study of protein structure. Despite its advantages, IM-MS has yet to see routine implementation in the clinical lab due to challenges in quantitation, limited universal standards, data processing software, and reproducibility across different IM techniques/vendor platforms. This workshop will introduce common IM techniques and their operating principles, expanding upon the benefits of incorporating IM into conventional LC-MS/MS workflows and discussing its challenges. More importantly, recent advances in hardware, software, and data processing approaches will be highlighted. Finally, an overview of current applications (including metabolomics, lipidomics, and proteomics examples) will be provided.

Syllabus

1. Basic Operating Conditions of IMS: Electric field application, experimental conditions (temperature, pressure, gas composition)
2. Different IMS techniques: Drift tube/traveling wave, field asymmetric/differential mobility, emerging techniques (i.e., TIMS, SLIM, cIMS, etc.)
3. Applications: Current examples from metabolomics, lipidomics, and proteomics

Participants will 1) learn the basic principles of isotopic effects and be able to explain how they can be used to study human metabolism, including drug metabolism, and 2) be able to explain how emerging measurements on bioanalytical mass spectrometers such as ESI-Orbitrap systems can perform accurate isotope ratios on molecular species.

Summary

Isotope ratio mass spectrometry (IRMS) measures the relative abundance of different isotopes of an element, providing valuable insights into the molecular mechanism of metabolic diseases, drug metabolism, and links between nutrition and health. In classical IRMS complex molecules are converted to low molecular weight gases, thus losing important intramolecular isotopic information. IRMS is now becoming possible on bioanalytical mass spectrometers such as ESI-Orbitrap systems.These recent advances give access to isotopic information in intact biomolecules, drugs, and metabolites. This workshop will introduce the principles that cause isotopic effects in the human body, introduce the technologies used to make highly precise measurements of isotope ratios in metals and biomolecules, and illustrate how recent advanced on doing IRMS using ESI-MS instrument can open new avenues of IRMS for biomedical and clinical research application. Methods and studies we highlight will help stimulate thought on new application areas for IRMS in biomedical research and eventual clinical diagnostics.

Topics Covered

* Principles that cause isotope effects in the human body
* IRMS technologies and current advances
* Applications of IRMS for biomedical and clinical research

Workshop : Surgical Mass Spectrometry – Delivering the Technology to the Operating Room
@ De Anza 1 (Portola Hotel > Ground Floor)

Zoltan Takats, PhD
Imperial College

Lauren Ford, BSc (Hons), PhD
Imperial College London


Objectives

To identify methods to deliver mass spectrometry guided surgery to become routinely used in the clinical interventional world. The workshop will focus on the interpretation of clinical information/data and how this should be fed back to healthcare professionals and ultimately patients. The workshop will highlight the limitations of current technologies and developments enabling clinical adoption.

Summary

The need for in-situ, real time tissue identification has been dramatically increasing with the development and deployment of robotic and other high-precision surgical approaches. While surgical mass spectrometry techniques have been continuously developed, published, and demonstrated in human surgical theatres, none of these approaches have reached regulatory approval and routine application in surgery. We will use this interactive setting to discuss overcoming current roadblocks to delivering technology for patients and healthcare professionals. The workshop will give an overview of the current mass spectrometry technology developed and the strengths and weaknesses in each approach. This will be followed by discussing the embedding of the approach both into existing oncology and clinical diagnostic systems. Using Mass Spectrometry in surgery will change how interventional cancer care is delivered, hence it is important to ensure data tools are developed which can be relied on. Delivery of the obtained clinical information in the operating theatre is also important to explore. As part of this workshop, we will discuss data visualisation strategies such as in the virtual reality space, delivery of feedback to the clinical healthcare professionals and tools developed to advance usability, such as navigation. Data interpretation in the wider context of clinical oncology will also be explored.

Syllabus/Topics

• Surgical mass spectrometry methods – strengths, weaknesses, applications and future perspectives
• Embedding of technology into healthcare systems. How to deliver clinical information, data interpretation, navigation guidance and feedback.
• Regulatory and health economics aspects.

Objectives

A case study approach will be used to demonstrate the following:
- Introduce tools used for unbiased biomarker identification and discuss recent discovery proteomics techniques
- How to utilize and mine discovery proteomics data to create targeted proteomics methods
- Demonstrate software tools and applications used to develop targeted methods

Summary

In this workshop, we will describe in detail the path from collecting and utilizing comprehensive information from various sources of discovery proteomics analyses to the creation of targeted proteomics methods for the verification of protein biomarkers. This workshop will be divided in two sections. In the first section, a discovery proteomics strategy will be discussed with a focus on the study design, the data acquisition approach, and the data analysis pipeline for biomarker selection. An example case study will be presented and discussed. In the second section, the attendees will be guided through a step-by-step instruction on how to utilize pertinent information acquired from the discovery approach to develop a targeted proteomics method. A brief introduction on Skyline and instructions on working with spectral libraries in Skyline will be included. Furthermore, technical aspects such as the choice of instrument, flowrate and acquisition strategy at every step of the targeted proteomics assay development will be tackled and discussed.

Workshop : Accreditation of Clinical Mass Spectrometry Laboratories
@ De Anza 3 (Portola Hotel > Ground Floor)

Judy Stone, MT (ASCP), PhD, DABCC
Clinical Chemist (retired)

Prof. Dr. med. Michael Vogeser
University Hospital, LMU Munich


Objective

To explain the basic principles, requirements, and processes of laboratory accreditation; with examples and a focus on laboratories that are in transition from research to patient care.

Summary

Many more countries are now requiring clinical laboratory accreditation to ISO 15189 or alternative standards. Accreditation presents a particular challenge for highly complex in-house testing such as mass spectrometry, but can also offer significant potential for improving processes and overall performance. Advantages and disadvantages of accreditation, risks, opportunities, and preparation strategies will be discussed. Extensive experience from both the perspective of the client and the assessor (inspector) will be shared. Our personal experience is with laboratory accreditation in the United States and the EU, but we will attempt to present these concepts from a global perspective.

What does it take for a biomarker to make the leap from research to the clinical laboratory? Through the lens of biomarkers for Alzheimer’s Disease and related neurodegenerative disorders, we’ll discuss the various steps of identifying promising biomarkers, developing and optimizing mass spectrometry assays to measure these biomarkers, and considerations for moving assays from research to the clinic. We’ll cover lessons learned from experience in the early development stages of mass spectrometry assays for neurofilament light (NfL), including the importance of selecting the right target peptides, as well as the role of multiplexing to create biomarker panels. We’ll also discuss perspectives from the clinical lab, such as understanding ROC curves, the role of prevalence, and the importance of having clear intended use criteria. This presentation will highlight the benefits of working collaboratively and how coupling perspectives from both basic research and the clinical laboratory can help advance patient care.

Plenary : Steroid Metabolomics for Diagnostic and Prognostic Biomarker Development
@ Steinbeck Ballroom (Conference Ctr > 2nd Floor)

Wiebke Arlt, MD DSc FRCP FMedSci
Medical Research Council Laboratory of Medical Sciences


I will discuss steroid metabolomics, the combination of mass spectrometry-based steroid profiling with machine learning-based steroid data analysis. I will provide two clinically relevant examples: (1) the development of a new diagnostic biomarker test for the detection of adrenal cancer, with a timeline covering the last 15 years and including discovery, optimisation and prospective validation - adrenal cancer is rare but regularly discovered upon the investigation of incidentally discovered adrenal nodules, which are detected in 5% of all cross-sectional imaging scans; (2) the exploration of the steroid metabolome in a large comprehensively phenotyped cohort of newly diagnosed and treatment naïve women with polycystic ovary syndrome (PCOS), a condition affecting 10-15% of women worldwide and associated with significantly increased metabolic disease risk. Showing our data from this cohort, I will describe the potential of steroid metabolomics for detailed phenotyping, mechanistic exploration, prognostic prediction and therapeutic stratification in this underserved population.

Plenary : Graham Cooks Lifetime Achievement Award & Mini-Lecture : Mass Spectrometry in Diagnostics and Therapeutics: the Long View
@ Steinbeck Ballroom (Conference Ctr > 2nd Floor)

Purdue University

This talk covers an as-yet-unfinished journey. It describes a suite of methods and instrumentation that is the work of many individuals over a long period. Applications to diagnostics, especially intraoperative diagnostics, are ongoing for brain and other cancers. The long view espoused here, describes a series of steps that stretches from half-century old mass spectrometry to new drug candidates, specifically for the case of prostate cancer.

1. MS and MS/MS: because mass spectrometry (MS) is a well suited to characterizing organic compounds, it can be used to characterize complex mixtures, provided sample ionization produces a corresponding mixture of molecular ions. This 1:1 transformation (molecule -> molecular ion) was first achieved by the then-new method of chemical ionization. This allowed two stages of mass analysis, MS/MS, to became an alternative to GC/MS (and later to LC/MS) for mixture analysis.[1]

2. Ambient ionization: the simplest, most direct form of MS, ionizes objects/materials/samples in the open air. Electrospray ionization provided the lead on atmospheric pressure ionization, but ambient ionization [2] goes further and avoids sample manipulation or purification. Desorption electrospray ionization (DESI) effects ionization by localized solvent extraction.[3]

3. MS imaging: any directed ionizing agent (ions in SIMS, neutrals in FAB, photons in LDI, droplets in DESI) is inherently an imaging method.[4]

4. Biomarker discovery: Comparisons of diseased and healthy tissue point to potential biomarkers, e.g. DESI MS/MS analysis of prostate tissue showed preferential localization of cholesterol sulfate in diseased tissue.[5].

5. Target validation: knockdown studies established an association of cholesterol sulfate transferase with prostate cancer.[6]

6. Late stage functionalization: High throughput DESI instrumentation [7] uses accelerated reactions in microdroplets [8,9] to synthesize large numbers of new drug candidates on the millisecond time scale.[10]

7. Enzyme inhibition: Collection of the functionalized products followed by enzyme kinetic measurements [10] validated inhibition for several particular compounds as potential prostate cancer drugs. 8. Animal, safety and efficacy studies lie in the future.

Discussion Group : FDA Regulation of LDTs
@ Bonsai (Portola Hotel > Ground Floor)

E. Ellen Jones, PhD
National Center for Toxicological Research, FDA


Regulation of LDTs or laboratory developed tests by the FDA has long been a topic of interest and discussion. With the advent of new technologies and approaches there remains a gap between what is analytically possible with newer instrumentation versus what is currently allowed for regulatory use. Clearly, the FDA is aware of new analytical methods and capabilities and knows that new guidance’s are needed. This workshop will discuss some of the historical information on these LDT’s and provide a perspective from a non-regulatory FDA research scientist who is also working on incorporating novel technologies to inform regulatory decision making within the FDA.

In this roundtable we will discuss where we are as a translational research community, the complexities, tools available to researchers, strategies employed, and considerations for the future.

Table 2: YYZ Pharmatech - Is a tsunami coming? The role for LCMS in Alzheimer's Disease diagnostics
Rob DeWitte and Mike Badeau

With the approval of Aducanumab, Lecanemab and Donanemab, treatment options available for care of patients with Alzheimer's Disease have changed dramatically. This has lead to new hope for patients experiencing cognitive impairment, and a renewed focus on identifying disease progression earlier.

Treatment changes have also begun to influence laboratory operations as new invitro tests based on CSF are serving as surrogates for expensive imaging-based diagnostics. Blood based tests are also on the horizon for the most important markers (i.e. Aβ(1-42)/Aβ(1-40), P‐tau181 and P‐tau217), with the important benefits of sampling patients non-invasively, lowering costs and scaling without new infrastructure.

This all leads to the question: Is a tsunami coming?

Please join YYZ Pharmatech as we host a discussion about the impact of these shifts on the clinical laboratory, including:

  • What tests are being offered, and where?
  • How are laboratories adapting their technologies and workflows to support these trends?
  • What are the operational challenges?
  • What technical challenges remain to be solved?
  • What potential benefits do LCMS methods provide?

Even though there is a need for definitive testing in clinical settings, there aren’t many guidelines available on what should be taken into consideration as laboratory directors tackle design and establishment of toxicology laboratory. This session will provide valuable information to early career professionals who may be tasked with starting up a toxicology section. Even though some vendors are available to assist with site design, site preparation responsibilities fall upon the site personnel. Thus, it is important to have a basic understanding of what is needed to start the project. This roundtable session will address many personal ‘lessons-learned’ based on experience working with design and construction team in an Academic Hospital Laboratory, including factors associated with space design (electrical needs, ventilation needs) that should be taken into consideration before unboxing the LC-MS/MS crates. Well-designed space will assist in facilitating seamless transition from instrument validation to method validations.

Objective 1: Understand the requirements for LC-MS/MS installation.

Objective 2: Discuss the journey of building a toxicology testing area from scratch.

Table 4: Don’t Slow Your Role: Moving the Needle on DE&I in a Damaged Workplace Culture
Carolyn Slade, Mikela Sanford

Diversity, equity, and inclusion (DE&I) goals cannot succeed as a standalone strategy in organizations where the culture is damaged. Signs of a damaged culture include favoritism, unconscious bias, and a lack of psychological safety. To be impactful, DEI initiatives require a strategic and intentional approach all year long, reaching all employees, and building equity into external programs and internal processes. What happens when two, black women who have suffered the most inequities, decide to move the needle on DE&I? Join this interactive roundtable discussion to hear how both transformed their experiences in toxic workplaces into achievable DE&I goals.

Attendees of this session will:

  • Discuss the signs of a toxic workplace and discuss coping mechanisms
  • Recognize DE&I does not begin or end with a specific title or place within an organizational chart
  • Identify ways you can foster an inclusive and diverse workplace culture, and uphold principles of psychological safety in everyday practice
  • Discuss tools and strategies for implementing DE&I principles in small group dynamic

Table 5: Do Identical Instruments Produce Comparable Patient Results? A Stumbling Block of Harmonizing LC-MS/MS Assays in Clinical Laboratories
Joyce Liao

Clinical mass spectrometry laboratories usually validate individual assays on more than one instrument for continuous operation. Instrument comparison is a requirement of the College of American Pathologists and should be monitored at least twice a year to ensure comparability of results. Although the same style of liquid chromatography-tandem mass spectrometry system is preferred to minimize the variations between instruments, labs will inevitably encounter bias between two or more identical LC-MS/MS systems. Even in the absence of bias, the same instrument model with two different serial numbers may require different instrument settings to obtain similar sensitivity and specificity. In this roundtable session, we will review several comparison data sets from the same extractions injected and analyzed on two LC-MS/MS systems of the same make and model. We will discuss the potential factors, including mass spectrometer hardware (probe type and cleanness), software settings (gradients, transitions, cone voltages, and collision energies), and matrix effect that could bias patient results and how to establish quality assurance policies to ensure adequate data review and accurate resulting. Examples of challenges we have faced and approaches we have found useful will be presented as a starting point for discussion.

Table 6: Use of Reference Materials for Calibration and Validation in Clinical Mass Spectrometry Applications
Ashley Beasley Green and Johanna Camara

Reference materials (RMs), including certified reference materials (CRMs), are provided by the National Institute of Standards and Technology (NIST) and other RM producers to support global clinical measurement standardization and harmonization. Standardization is when clinical results are uniform across routine clinical methods and traceable to the International System of Units (SI) via higher-order RMs and Reference Measurement Procedures (RMPs). However, harmonization is established to make clinical results more equivalent across clinical methods when no higher-order RMs or RMPs exist. To support both systems, RMs are available in various forms, including neat powders, solutions, and clinical matrices and the intended uses include calibration and validation, depending on the material. The choice of which RM to use and how to incorporate it into a measurement system depends on laboratory goals. Many RMs are ideally suited for mass spectrometry-based measurement procedures. Many matrix matched RMs (blood serum, plasma, urine) are value assigned based on mass spectrometry-based RMPs. These RMPs typically separate and quantify individual peptides, metabolites, epimers, or other chemical variations of clinically relevant measurands that are not necessarily separated and detected by other laboratory techniques, such as immunoassays or microbiological assays. This roundtable is designed to discuss RM production, availability, and options for incorporating RMs into clinical applications. RM users may also need to propagate the measurement uncertainty of RMs or other calibrator values to clinical results. Therefore, the factors that should be accounted for when estimating measurement uncertainty will also be highlighted in the roundtable discussion.

Table 7: Quality Control Strategies for Large, Multiplexed, Omics Panels
Tim Collier, Steve Master, Brian Wilcox

Objective: Discussion of quality control strategies for large, multiplexed LC-MS Omics Panels

Summary: Recent Technological developments in LC-MS/MS instrumentation and bioinformatics approaches have enabled rapid, reproducible, and robust quantitative strategies for the measurement of hundreds, if not thousands of analytes that have the capacity to revolutionize the contribution of mass spectrometry based omics measurements to precision medicine. However, a major hurdle to the translation of large panels into a regulated clinical laboratory environment is how to properly deploy quality control (QC) standards. In this workshop, an expert panel of laboratory scientists and clinical chemists, with active discussion of the participating audience, will discuss how we might begin to address these challenges.

Topics Covered:

  • A review of CAP/CLIA Quality Control Standards as deployed for small scale assays.
  • Identification of the barriers current standards may present to the deployment of large omics panels in the CAP/CLIA regulated clinical laboratory environment.
  • Expert panel and audience-driven discussion of potential strategies for ensuring proper assay QC, i.e. how panels can be adapted to current regulatory frameworks and/or proposing novel QC strategies that may satisfy CAP/CLIA regulatory frameworks.

Table 8: Roche - The Future and Beyond: A discussion on future assay menu needs for mass spectrometry in the busy clinical laboratory
Alex Chin and Allyson Kozak

For decades, immunoassays were considered by many the gold standard for analyte detection in the clinical lab. However, the need for improved sensitive and accurate complementary clinical laboratory methods grew in response to certain challenges in immunoassay performance. Mass spectrometry is renowned for its high sensitivity and accuracy and is therefore considered the gold standard in several clinical indications and has steadily become more prominent in today’s busy clinical laboratories. However gaps need to be addressed in the demands for a diverse test menu to serve a variety of clinical specialties and emerging disease areas. This roundtable will be an open forum to discuss gaps and pain points in current mass spectrometry assay test menus, what can be done to address current unmet and future needs in the clinical laboratory and to facilitate its adoption for improved patient outcomes.

Objectives:
1. Define what gaps exist in current mass spectrometry testing
2. Describe the pain points in current mass spectrometry testing
3. Identify potential future clinical indications for mass spectrometry testing

Table 9: Ionpath - From Bench to Map: Simplifying the MSi Spatial Proteomics Workflow
Sean Pawlowski

Multiplexed ion beam imaging (MIBI) is a technique that has simplified numerous issues present in MS workflows within spatial imaging. Compared to other MSi techniques, MIBI ™ presents a sample preparation workflow identical to fluorescence microscopy while also eliminating the need for messy spectral deconvolution to identify antibody targets. ToF-SIMS as the backbone of MIBI allows for multiple scans on a single ROI to glean more than surface-level information. Coupled with existing and custom data analytics tools, Ionpath’s spatial proteomics services help biologists answer fundamental questions about cellular and spatial interactions. Join this interactive session to discuss the spatial proteomics workflows used to extract information from this complex data and how MIBI can complement it.

Attendees of this session will:

  • Discuss the growing pains of MSi in the spatial biology world
  • Examine how MIBI technology can strengthen their spatial biology capabilities
  • Look at the current state of spatial workflows
  • Discuss the gains where MIBI technology can simplify the difficulties present in other MSi workflows
  • Discuss the gaps present in the analysis of data in spatial biology

Table 10: Forever and Always - PFAS Monitoring in Human Matrix
Carrie Adler

Is human testing of per- and polyfluoroalkyl substances (PFAS) the next frontier for detecting and quantifying the “forever chemicals” that are now everywhere? PFAS regulations have been proposed or currently exist for drinking water, food packaging, and consumer products. PFAS cleanup and remediation are now being proposed for the 400+ PFAS compounds on the Environmental Protection Agency (EPA) list, however thousands of compounds exist. This brainstorming roundtable will focus on how biomonitoring would best be achieved.

Key Discussion Points:

  • What are the drivers for human PFAS testing?
    • Current and anticipated regulations.
    • Direct to consumer requests.
    • With proposed environmental remediations, will repeat monitoring be required?
  • Who is currently performing PFAS biomonitoring? Why?
  • What are the challenges for targeted PFAS assays?
  • What are the future PFAS research topics?
    • Untargeted discovery approaches.
    • Excretion profile and matrix considerations.

Identifying Blood-Based Markers of Universal Resilience

UC San Diego and the Wellcome Leap Dynamic Resilience Program

Major Contract Funds Study on Drivers of Resilience Among Older Adults

A multi-disciplinary team of researchers at the University of California San Diego, led by Anthony J.A. Molina, a professor in the Department of Medicine, has launched a new project to better understand why older adults who share the same age and similar health characteristics can have vastly different trajectories following stress events such as fall-related injuries.

This project is funded through a contract with Wellcome Leap’s $60 million Dynamic Resilience program, which is jointly funded with Temasek Trust. The Dynamic Resilience program seeks to identify and validate markers of health resilience that can be used to develop and test preventative interventions that support resilience in people at risk of deterioration after a stress event.

During his presentation, Dr. Molina will delve into the journey that has brought the team to this pivotal point and outline their anticipated achievements in the years to come.
