Whole genome sequencing (WGS) is being implemented for surveillance of foodborne pathogens in Denmark as a cost-effective alternative to traditional typing methods. WGS allows for multiple analyses from a single test, including serotyping, virulence profiling, antimicrobial resistance determination, and high-resolution typing for outbreak detection. Validation studies have shown WGS performs comparably or better than existing methods for various pathogens. WGS implementation has improved detection and investigations of outbreaks of Listeria and E. coli in Denmark. International collaboration is key for effective use of WGS in foodborne disease surveillance.

This document summarizes and compares different methods for comprehensive chromosome screening (CCS) of human oocytes and embryos. It discusses the capabilities and limitations of various CCS methodologies, including:
1) Array comparative genomic hybridization (aCGH), single nucleotide polymorphism (SNP) microarrays, quantitative real-time PCR (qPCR), and other technologies can screen all 24 human chromosomes, unlike previous fluorescence in situ hybridization (FISH) methods.
2) CCS methods vary in terms of accuracy, minimum detectable imbalance, ability to predict monogenic diseases and origins of aneuploidy, and time required to obtain results. SNP microarrays and qPCR allow for results in time for fresh
The study assessed screening for colonization with KPC-producing Gram-negative bacilli (KPC-GNB) using fecal swabs in patients at a 735-bed hospital with endemic KPC-GNB. Over 6 months, 258 fecal swabs were collected from consenting inpatients, but only 1 sample tested positive for KPC-GNB. Despite 138 patients having clinical cultures positive for KPC-GNB during the study, active surveillance cultures identified few carriers. The study suggests screening strategies relying on fecal swabs may not be effective for detecting KPC-GNB colonization and preventing transmission.

The document discusses the validation of interleukin-8 (IL-8) as a biomarker for melanoma. A study was conducted using 59 melanoma tumor tissue samples and matching serum and plasma to validate that IL-8 is elevated in melanoma. However, the results were inconsistent, as IL-8 protein levels appeared sensitive to freeze-thawing of samples. The author advocates for increasing the quality rather than quantity of biomarker research through improved collaboration to ensure better data and validation.

Assay Standardisation - how this leads to improved patient resultsWalt Whitman
Clare Morris from NIBSC discusses the importance of assay standardization for improving patient results. Standardization leads to more accurate, robust and reproducible diagnostic assays by providing a common unit of measurement for comparison. This allows results from different laboratories and assays to be comparable. NIBSC establishes biological reference standards and reference materials to facilitate standardization. Examples are given showing how standardization has improved comparability for assays measuring PSA, HCV RNA, HIV RNA, and other markers. Challenges in standardizing assays across different sample matrices are also discussed.

Cell Therapy Expansion and Challenges in Autoimmune DiseaseHealth Advances
There is increasing confidence that cell therapies will soon play a role in the treatment of autoimmune disorders, but the extent of this impact remains to be seen. Early readouts on autologous CAR-Ts in lupus are encouraging, but manufacturing and cost limitations are likely to restrict access to highly refractory patients. Allogeneic CAR-Ts have the potential to broaden access to earlier lines of treatment due to their inherent cost benefits, however they will need to demonstrate comparable or improved efficacy to established modalities.
In addition to infrastructure and capacity constraints, CAR-Ts face a very different risk-benefit dynamic in autoimmune compared to oncology, highlighting the need for tolerable therapies with low adverse event risk. CAR-NK and Treg-based therapies are also being developed in certain autoimmune disorders and may demonstrate favorable safety profiles. Several novel non-cell therapies such as bispecific antibodies, nanobodies, and RNAi drugs, may also offer future alternative competitive solutions with variable value propositions.
Widespread adoption of cell therapies will not only require strong efficacy and safety data, but also adapted pricing and access strategies. At oncology-based price points, CAR-Ts are unlikely to achieve broad market access in autoimmune disorders, with eligible patient populations that are potentially orders of magnitude greater than the number of currently addressable cancer patients. Developers have made strides towards reducing cell therapy COGS while improving manufacturing efficiency, but payors will inevitably restrict access until more sustainable pricing is achieved.
Despite these headwinds, industry leaders and investors remain confident that cell therapies are poised to address significant unmet need in patients suffering from autoimmune disorders. However, the extent of this impact on the treatment landscape remains to be seen, as the industry rapidly approaches an inflection point.

• Glycoprofile of intact transferrin protein (80 kDa)
• Identified through combination glycoproteomics and exome sequencing
• Is linked to specific glycosylation disorders (rare metabolic diseases)
• Implemented now in clinical care as diagnostic mass spec test
• Treatable disorder (dietary intervention)

30. A short story: Personalized medicine in melanoma
B-RAFV600E mutation Strong growth of cell Growth of tumor
• B-RAFV600E cells always grow and become cancer cells
• RAF inhibitors will block pathway, block cell growth
and inhibit cancers that have a B-RAFV600E mutation
• 60% of melanoma patients have B-RAFV600E mutation
• Basis for a personalized medicine !

31. Biomarkers to support clinical development
• Within Schering-Plough 4 Lead Optimisation programs in ERK pathway (2009)
• Need for blood-based biomarker that indicated downstream effects of drugs:
• Inhibition ERK pathway (pharmacodynamic)
• Tumor inhibition (efficacy)
• Extensive transcriptomics profiling: IL-8 as promising candidate biomarker

Literature
{Yurkovetsky, et al. Clin Cancer Res, 2007}
Objectives:
• Confirm elevated IL-8 in melanoma
• Develop IL-8 assays for clinical use
32 Alain van Gool, HUPO, Dublin, 20 Sept 2017
33. Validation study to confirm IL-8 in melanoma
Stage 1 Stage 2 Stage 3 Stage 4
H&E staining; 20x
59 melanoma samples (tumor tissue (ffpe) + matching serum & plasma, stage I-IV,
from two independent biobanks) + 40 healthy serum & plasma samples
1. Genetic analysis for BRAFV600E/D mutation in genomic DNA from tissue
2. IL-8 mRNA analysis in tissue samples by in situ hybridisation using bDNA
probes (multiplexing with 12 ERK pathway response transcripts)
3. IL-8 protein analysis in tissue samples by immunohistochemistry (in parallel
with 4 other ERK pathway response proteins, Ki67, Tunnel)
4. IL-8 protein analysis in matching plasma and serum by IL-8 immunoassay
(3 formats: ELISA, Luminex, Mesoscale; singleplex and multiplex)

34 Alain van Gool, HUPO, Dublin, 20 Sept 2017
35. Lessons learned?
Particularly for this case:
1. Know sample history
• IL-8 protein appeared sensitive to freeze-thawing
2. Know all relevant information from the source (patient)
• Tumor load may be too low for our patients
3. Do these type of expensive validation studies together !
• Share burden, increase power, ensure better data
If we want to innovate clinical molecular biomarkers,
we need to increase quality, not quantity of our research.

46. 2. Need for innovation in protein biomarker diagnostics
Current diagnostic protein assays:
• Focus on assay simplicity, robustness,
throughput, costs
• Often sandwich/turbidity-immunoassay
format. MRM MS slowly emerging.
• Mostly protein abundance
• Often unknown epitope of detection
• Ignore occurence of proteoforms
Room for innovation !
