Relevant Financial Disclosures (within past 24 months, reported on Sep 11, 2025) No relevant financial relationship(s) to disclose. Objective This workshop is designed to teach attendees reasons why most biomarkers do not translate to clinical diagnostics as a way to improve the process for future research Summary Biomarker discovery is one of the major areas of clinical research especially in metabolomics yet less than 1% of published biomarkers translate to clinical diagnostics. Biomarker discovery generally starts in phase 1 with a few samples to identify a biomolecule that differentiates the disease or disorder under investigation from control samples. Once a biomolecule is selected a targeted quantitative method would be developed in phase 2 to use on a larger number of samples to validate the results from phase 1. There are several common reasons for biomarker failure such as using samples that are not representative of the clinical population, not including diversity in the initial discovery phase, improper use of statistical approaches, not having a sufficient number of samples and improper quality control for analysis. With the growth of metabolomic methods recently, a discussion on approaches to help improve phase 1 of biomarker discovery is important to have confidence that the selected markers are indeed unique. Syllabus - Metabolomics in clinical research - Quality control for better method assessment - Experimental design - Statistical analyses with validation - Real-world samples 1897

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 three days (one in person to start and two online later) and time will be evenly split between didactic sessions and hands on problem solving with real data sets. Drs Holmes and Bunch 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 R Studio interface installed. Students may use Windows, Mac OSX or Linux environments.

Relevant Financial Disclosures (within past 24 months, reported on Apr 26, 2022) Not yet reported. Objectives The objective of this workshop is to give attendees the knowledge necessary to put together a convincing business case for purchasing a mass spectrometer. This knowledge will be imparted by presenting and discussing successful and unsuccessful examples of such business cases. Throughout the course, essential business terminology will be presented and explained. Summary Many laboratorians can discuss the benefits of implementing mass spectrometry into the clinical laboratory. From improved confidence in results to minimization of interferences, there are substantial and well-discussed benefits to mass spectrometry. Unfortunately, mass spectrometers cost money and the individuals empowered to write checks rarely relate to such technical justifications. This workshop is designed to help clinical laboratorians understand what factors matter to financial decision makers. The presenters include a clinical laboratorian with experience successfully acquiring mass spectrometers and an experienced administrator with significant laboratory and financial expertise. The presenters will walk attendees through the process of preparing a business case. Attendees will be presented with numerous examples of business cases that need improved and the attendees will be given the chance to discuss what is wrong and what needs to be done to fix them. Attendees will also be given a chance to submit their own personal business cases ahead of time if desired. These can be discussed in private after the workshop or (with attendee permission) can be discussed in part as part of the workshop. The goal is to prepare attendees to put together and present a business case that supports the acquisition of a mass spectrometer in terms that matter to financial decision makers. Syllabus/Topics How to assemble the worst business case ever (and guarantee failure) Attendees will begin the session with an introduction to the worst possible business case one can present. The numerous flaws will be pointed out and addressed in an effort to highlight the many ways business cases can go wrong. From LCMS and qTOF to ROI and DEPR (speaking the language of finance) After attendees have a chance to see what not to do, it will be time to discuss what administrators/finance officers are looking for in a business plan. The goal is that attendees walk away with an understanding of the important terms and metrics their business cases will be evaluated by. In addition, an overview of hospital accounting and do's and don't's of capital equipment purchasing will be given. Estimating costs The cost of a mass spectrometer is far more than the instrument itself. This section will help attendees begin to consider everything they need to account for when proposing how much mass spectrometry will cost- labor, supplies, service contract, etc. Estimating reimbursement This section will cover how to estimate revenue- whether it is insourcing from a reference lab or setting up a new service line. The importance of payer mix and inpatient vs outpatient will be addressed What's wrong with my business case? Ending where the course started, the final section will cover examples of business cases. These cases will be used to illustrate cases that are very strong and those with weaknesses that can be improved. If submitted by attendees ahead of time, these example cases will be anonymized versions of those submissions. 1896

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 bioanalytical assays. The workshop is focused on practical implementation of DoE and will demonstrate how method development of UPLC-MS/MS clinical diagnostic methods can become much more efficient by utilizing DoE. Summary The chemometric approach, design of experiments (DoE) is an efficient tool for development and optimization of UPLC-MS/MS for quantification of biomarkers in complex biological matrices. The UPLC-MS/MS platform is composed of several processes which involves many experimental factors that need to be simultaneously optimized to obtain maximum sensitivity with adequate resolution at minimum retention time. DoE offers a practical approach for performing experiments in accordance to predefined plan, modelling by empirical functions, and graphical visualization. Basic concept of DoE will be presented with emphasis on practical implementation of DoE which include the three main stages, screening, optimization, and robustness testing. Example from optimization of a UPLC-MS/MS method for clinical diagnostic purposes and therapeutic drug monitoring will be used to show the cost-effective benefit of DoE, where it allows the effect of variables to be assessed with only a fraction of the experiments that would be required by changing one-separate-factor-at-time (COST) approach. A fractional factorial design was used for experimental screening to reveal the most influential experimental factors. When multi-levels qualitative factors were included in the screening experiments D-optimal design was applied. Significant factors were studied via central composite design and related to sensitivity, resolution and retention time utilizing partial least square (PLS)-regression. A specific and reliable UPLC-MS/MS assay for simultaneous quantification of urinary 2,8-dihydroxyadenine (DHA) and adenine was optimized efficiently with DoE. The assay has been implemented for clinical diagnosis and therapeutic drug monitoring of patients with adenine phosphoribosyltransferase (APRT) deficiency, which is an inborn error of purine metabolism.

Objective Workshop attendees will learn about the basic operating principles of various ion mobility techniques, the potential benefits and challenges to its routine implementation in the clinical lab, and several potential 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 and folding dynamics. Despite its many 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 IMS techniques/vendor platforms. This workshop will introduce the common IMS techniques (e.g., drift tube, traveling wave, FAIMS/DMS, etc.) and their operating principles, expanding upon the benefits of incorporating IMS into conventional LC-MS/MS workflows and discussing the challenges that have limited such incorporation. Finally, an overview of current applications (including metabolomics, lipidomics, and proteomics examples) will be provided. 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 current (and potentially future) applications of IMS to the clinical lab 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.

As medical science continues to make gains in the elucidation of disease pathophysiology and the discovery of cures , some have questioned the value of dedicating dwindling financial resources to maintaining wellness rather than to fighting disease per se. While both approaches are meritorious and complementary, neither approach is alone sufficient to ensure the health of a population. One major problem with the focus on wellness is the Bayesian dilemma that the positive predictive value of clinical laboratory testing in apparently healthy people is often low, as the specificities of few clinical tests are high enough to ensure that most positive results are true. The impact of this dilemma on laboratory-based wellness approaches will be discussed.

The mutational status of a solid tumor can predict the therapeutic efficacy of a specific drug in a molecularly defined subset of patients. Targeted therapies are available to treat advanced (stage II – IV) ovarian cancer with mutations in BRCA1/2 genes. Unfortunately, there is considerable inter-patient heterogeneity in BRCA1/2–based determinations of drug treatment sensitivity. Determining the proteome-level mechanisms of drug treatment sensitivity could enhance our ability to select the ovarian cancer patient populations that would benefit the most from these targeted therapies, consequently improving survival and overall treatment response. Our laboratory is applying mass spectrometry-based proteomics to identify protein signatures of drug treatment sensitivity and subsequent patient stratification for treatment. This presentation will provide an overview of the experimental models and analytical approaches that we are utilizing toward a long-term goal of identifying prognostic protein biomarkers of drug treatment sensitivity in patients with high-grade serous ovarian cancer.

As a faculty member, she received the NIH NHGRI K99/R00 Pathway to Independence Award, a Sloan Faculty Fellowship, and an NSF CAREER Award. Professor Engelhardt’s research interests involve developing statistical models and methods for the analysis of high-dimensional biomedical data, with a goal of understanding the underlying biological mechanisms of complex phenotypes and human disease. Relevant Financial Disclosures (within past 24 months, reported on Dec 01, 2021) Not yet reported. Spatial single-cell technologies have enabled the comprehensive study of complex tissues and organs at a single-cell level. However, the statistical methods to perform analyses have not kept pace with the technologies for measuring spatially-resolved genes and proteins in tissue samples. In this talk, I will present two methods that allow the study of spatially-resolved proteomics data. First, nonnegative spatial factorization develops a low-dimensional representation of the spatially-resolved samples to identify variation in protein expression across space. Second, Gaussian process spatial alignment allows multiple slices from different technologies to be aligned to a known or unknown common coordinate system, enabling the construction of a tissue atlas from disparate samples of that tissue type.

The COVID-19 pandemic has been a challenging time for clinical laboratories, but it has also improved awareness of the important role labs play across health care and public health domains. The University of Washington Department of Laboratory Medicine and Pathology has worked to establish diagnostic SARS-CoV-2 testing as a widely available resource over a large footprint of our state by combining expertise in laboratory testing and informatics with community partnerships to expand testing access and convenience. Over the course of the pandemic the needs of our laboratories as well as of the public and of public health authorities have evolved. Staffing and supply chain challenges have placed a greater emphasis on efficiency and productivity. The need for genomic surveillance of the evolving virus has required a close integration of clinical workflows with research-focused genomics workflows. Increased demand for services coupled with record high positivity rates during the omicron surge has challenged our model for expanding capacity using sample pooling. This presentation will describe the evolution of our testing program and infrastructure amidst these challenges, highlighting the informatics capabilities we needed to adapt. Finally, we will discuss what needs and capabilities are likely to persist beyond the pandemic and how the lessons we have learned can better equip laboratories to improve the health of the public.

The Gelb lab has published more than 500 papers and 100 patents in biological chemistry. The Gelb laboratory has developed mass spectrometry for worldwide newborn screening of lysosomal storage diseases (the latest expansion of newborn screening panels). Relevant Financial Disclosures (within past 24 months, reported on Jun 17, 2025) Not yet reported. Our laboratory has been developing tandem mass spectrometry (MS/MS) for worldwide expansion of newborn screening (NBS) panels to include an ever-increasing collection of treatable genetic diseases. There is widespread discussion on the use of whole genome and whole exome DNA sequencing in population-wide NBS. The intersection of biochemical- and DNA-based NBS is an interesting topic now under heavy discussion. We will highlight the development of liquid chromatography-MS/MS (LC-MS/MS) for multiplex NBS of a large panel of treatable genetic diseases in newborns. Next generation sequencing (NGS) is also employed currently as a second-tier analysis after LC-MS/MS assays. We will also illustrate how it is possible to carry out first-tier NGS followed by second-tier LC-MS/MS NBS. LC-MS/MS is used together with enzyme substrates and biomarkers to monitor the activity of a large collection of enzymes and to measure the abundance of biomarkers in dried blood spots on NBS cards. We will focus on multiplex methods and then zoom in one a more detailed analysis of one disease called metachromatic leukodystrophy (MLD). We carried out a pilot MLD NBS study and determined that the rate of false positives out of 28,000 newborns screened is essentially zero showing the power of LC-MS/MS for NBS of this lysosomal storage disorder. In the second arm of the study, we have been measuring the activity of the enzyme relevant to MLD on a large collection of gene variants that are found in allele databases and for which no pathogenic information is reported. We show how we can integrate these efforts to provide for a highly efficient NBS program for MLD. We screened ~28,000 newborns for elevated sulfatide lipid, the biomarker that is relevant to MLD and found 180 high sulfatide newborns. These were submitted to an assay of the activity of the relevant enzyme, arylsulfatase A, and all but two showed normal levels of activity. DNA sequencing was carried out on 2 newborns, one with 0% and one with 8% of normal ARSA activity. The newborn with 0% activity was confirmed to have MLD, the other was shown to not have MLD. On the DNA front, we created a phenotype matrix that allows one to input the ARSA enzymatic activity of each variant to provide a composite genotype, and to make a prediction of the phenotype associated with this genotype. We show that this method is 83% accurate at predicting the true set of phenotypes observed in MLD patients. Massively multiplexed NBS of genetic diseases in newborns is possible using LC-MS/MS, and when used with second-tier NGS leads to a successful NBS platform. We show that it is also possible to carry out NGS as a first-tier NBS step and to clarify the results with second-tier biochemical assays based on LC-MS/MS. Thus LC-MS/MS meets DNA and DNA meets LC-MS/MS, and this provides a framework for the future employment of both LC-MS/MS and NGS in expansion of population based NBS.

Utilization of Mass Spectrometry to Discover and Develop Novel Biomarkers to Support Drug Development @ De Anza Veronica Anania, PhD Genentech Experienced researcher with Ph. D. in Molecular and Cell biology with over 10 years experience in immunology, protein biochemistry, and methods development. Strong neuroimmunology biomarker strategist and mass spectrometry group leader. Relevant Financial Disclosures (within past 24 months, reported on Jan 25, 2022) Not yet reported. Biomarkers play an important role in the drug development process including providing necessary insights into target engagement, dose selection and mechanism of action of candidate therapeutics. LC-MS is uniquely positioned to enable accurate quantitation of both small and large molecule biomarker candidates, however, the process of going from biomarker discovery to a multiplexed targeted MRM panel in clinical samples is long and resource intensive. Moreover, biomarker candidates often fail to replicate when tested in large clinical cohorts. Recent advances in data-independent MS (DIA-MS) have made this technology more accessible and certain benefits of DIA-MS including reproducible label-free analysis of hundreds of samples, ability to capture low abundance ions over a high dynamic range, and deep proteome coverage makes this technology well suited to streamline translational proteomics. One major hurdle for using DIA-MS to support drug development is that the quantitative range for most DIA-MS methods has not been well characterized and thus, quantitative conclusions drawn by prior studies that have employed this approach have been controversial. Here, we describe challenges associated with applying DIA-MS methods to address questions associated with clinical development and introduce best practices for establishing quantitative criteria for DIA-MS approaches in clinical trial samples. Results and lessons learned from both discovery and targeted clinical biomarker studies will be discussed and a model for a more streamlined biomarker development workflow that conserves resources and provides more comprehensive proteomic information from clinical trial samples will be discussed.

Objectives - Identify common challenges with reflexive urine drug screening - Discuss the utility of 'hybrid' testing and direct to definitive testing using mass spectrometry - Address the importance of drug panel test selection, and the potential issues with specific drug classes - Describe the value of providing interpretive reports for urine drug testing, particularly for pain management clients Workshop Summary Many clinical laboratories continue to utilize a traditional urine drug testing algorithm involving an initial screen, typically via an automated immunoassay, followed by confirmation of positive and/or unexpected results using mass spectrometry. This algorithm emerged in the 1970s and 1980s from the desire to test for the use of illicit substances in the military and other workplaces. It was designed to answer the question: Are employees upholding a drug-free workplace? This algorithm presents significant limitations in many clinical situations, particularly in the areas of pain management and substance use disorder treatments, where the primary question changes to: Is my patient taking their medication as prescribed? This workshop will discuss several alternatives for urine drug testing, such as direct to mass spectrometry testing and 'hybrid' panels. It will also discuss considerations for selecting the appropriate analytes for urine drug testing panels and potential pitfalls associated with certain classes of drugs. Finally, it will introduce our recent efforts to implement the use of interpretive reporting for pain management clients. 1940

Objectives It is the objective of the workshop to provide an introduction into pre-analytical considerations for clinical application of MS-based analytics, with a special focus on lipids. However, these considerations are in many cases independent of specific analytes of interest and can hence be applied for polar metabolites as well as proteins. The workshop is focused on main hurdles to be considered when performing clinical research using LC-MS based determination of lipids namely: (I) pre-analytical sample handling, (II) frequent generation of patient samples as well as (III) overall cohort and study design. Summary Lipids are involved in a broad spectrum of functionalities in the organism and implicated in a variety of physiological and pathological processes. Changes in lipid levels are promising biomarkers for early diagnosis, prognosis of disease progression, or guidance for selecting promising therapeutic approaches. However, biomarker discovery in the field of lipidomics is a very challenging process since lipids require specific procedures regarding sampling (including selection of sample type and collection procedures, storage conditions and number of freeze-thaw cycles), sample preparation and analysis for reliable determination. As especially pre-analytical sample handling is a critical step for the reliable analysis of the lipidome, a close cooperation with the clinicians is necessary. This ensures following a highly standardized protocol for venous blood sampling to avoid several pre-analytical pitfalls potentially changing the lipid profile ex vivo. As collecting venous blood samples is very laborious for patients as well as clinicians, other ways for a more frequent sample collection are necessary. Therefore, capillary blood sampling using microsampling devices is an auspicious way to complement the strategy of analyzing venous blood-based samples taken in the clinics. Besides considering the right sampling strategy, the structured recording of sampling details and subject metadata, the overall planning of the study and also the cohorts to be included is of high relevance. All mentioned points have to be considered before starting a clinical research project applying lipidomics to generate high quality data making biomarker discovery possible. Syllabus - Pre-Analytical factors influencing lipid concentrations - Capillary vs. venous blood sampling - the potential of microsampling - Cohort & Study design for lipidomics in clinical research 1883
