Development of Metabolomics Data Integration Methods and Software

In the short term, this topic aims to 1) develop bioinformatic methods to integrate metabolite data across various laboratory platforms and analytical technologies, including liquid-chromatography-mass spectrometry (LC-MS), gas chromatography-mass spectrometry (GC-MS), and NMR; and 2) develop scalable software tool(s) to automate these methods for use by the cancer and overall public health research communities. Valid and reliable data harmonization of metabolomics data also builds a critical foundation for the longer term goal of integration of metabolomics data with other ?omics data (e.g., genomics, proteomics, transcriptomics, epigenomics, etc.). The development of methods to integrate a wide range of -omics data will position the research community to better leverage existing data for the discovery of novel cancer biomarkers of etiology, diagnosis, and prognosis.
Responses to this topic are expected to address the development of efficient bioinformatic methods to:
1. Demonstrate bioinformatic methods for the integration of metabolite data across different laboratory platforms and analytical technologies with high accuracy;
2. Store metabolite data from the different data sources in databases that can be easily used for data integration and quality control protocols;
3. Implement valid quality control (QC) checks; and
4. Appropriately secure data at each stage of transfer and storage.
An essential task for each proposal is the development of bioinformatic tools in the form of scalable software that can be used by the research community at-large to automate complex data integration tasks for metabolomics data sources.
Phase I activities should provide evidence that metabolite data integration bioinformatic methods, using identified metabolite data, have been effectively developed, can be implemented across data inputs from diverse laboratory platforms and at least two analytical technologies, and demonstrate readiness to proceed to Phase II. Additionally, Phase I will be used to demonstrate the framework for scalable software tool(s) that apply the bioinformatic methods to automate the integration of metabolite data.
Phase I Activities and Deliverables
? Establish a project team including proven expertise in metabolomics analytical technologies, epidemiology, biostatistics/bioinformatics, and computer technology. Additionally, a team including expertise in biochemistry/clinical chemistry is preferred.
? Develop bioinformatic methods for metabolite data integration for identified metabolites across data inputs from diverse laboratory platforms and at least two analytical technologies (preferably liquid-chromatography-mass spectrometry (LC-MS), gas chromatography-mass spectrometry (GC-MS), and/or NMR).
? Participate in the development of a collaboration agreement between the offeror, NCI, and NCI-identified third party sources to access relevant input data types for the proposed project. NCI staff will work with established cohort studies and consortia to provide metabolomics data (identified metabolite data) to successful offerors.
? Develop database formats that support the import and export of individual datasets and ?combined? datasets, store structured data from different sources of metabolite data, and are readily used for data integration and QC protocols.
o Finalize database formats and structure, data collection, transport and importation methods for targeted Phase I data inputs.
? Provide wireframes and user workflows for the proposed Graphical User Interface (GUI) and software functions that:
o Support the import and export of individual datasets and ?combined? datasets;
o Implement, script or automate all features and functions of the data integration tool(s);
o Conduct QC of ?combined? datasets.
? Provide a report including a detailed description and/or technical documentation of the following:

Phase II Activities and Deliverables
? Expand the bioinformatic methods to include unidentified metabolite peaks, in addition to identified metabolite data, and demonstrate metabolite data integration across data inputs from diverse laboratory platforms and at least two analytical technologies (preferably liquid-chromatography-mass spectrometry (LC-MS), gas chromatography-mass spectrometry (GC-MS), and/or NMR).
? Participate in the development of a collaboration agreement between the offeror, NCI, and NCI-identified third party sources to access relevant input data types for the proposed project. NCI staff will work with established cohort studies and consortia to provide metabolomics data (identified metabolites and unidentified peak data) to successful offerors that would serve to: 1) train and validate the expanded bioinformatic methods; and 2) demonstrate the application of these methods through scalable software to automate complex data integration tasks for metabolomics data sources.
? Demonstrate usability of scalable software through the following:
o Beta-test and finalize automated file transfer, database importation protocols, metabolite data integration applications and reporting tools developed in Phase I
o Develop beta-test, finalize, and demonstrate the GUI
o Demonstrate the software systems ability to integrate data from planned Phase II technology compatibility matrix data sources using automated algorithms and analytic methods
? Conduct usability testing of the GUI elements of the metabolite data integration tool(s).
? Develop systems documentation where applicable to support the software and bioinformatic methods.
? In the first year of the contract, provide the program and contract officers with a letter(s) of commercial interest.
? In the second year of the contract, provide the program and contract officers with a letter(s) of commercial commitment.
