Clinical Biomarker Discovery Use Case 1
● Business unit with established & active biomarker discovery process
● Samples are routinely sent out for profiling at different platforms
● Data are generated routinely both from CRO & internal groups● High throughput profiling data● Low throughput imaging & assay data (IHC, ELISA, qPCR, etc.)
● Situation● Biomarker team reps are overwhelmed by data management
related questions with little time to do actual analysis
● Critical need● How to organize data effectively?● How to manage the low throughput data systematically with data
from clinical & high throughput data?● How to search & find the relevant data quickly?

AnalysisAssayProgram Study
Each object (Program, Study, Assay, etc.) is tagged with metadata:– Provide information on the object– Enable queries using search
Predefined annotation templates– Most fields use CV with pick-list or
autocomplete functionalities. Examples of dictionaries used: MESH, WhoDD, some branches Nextbio Ontology.

●Goal is to identify disease progression biomarkers than the current clinical functional test
● Situation at hand● Researchers don’t have any appropriate analytical tools for
correlative analysis● A variety of profiling experiments are being planned
• RNAseq, Proteomics, RBM, miRNA, Metabolomics● Patient data at multiple time points are collected
● Critical need● How to integrate all the data?● How to enable clinical researchers to analyze and visualize data?● How to analyze time series data more effectively?
