CDISC (Clinical Data Interchange Standards Consortium) is establishing new standards for exchange, storage and archival of clinical data.
The most important of these standards are the ODM (Operational Data Model), for the archival and exchange of clinical data between sponsors, CROs and Data Management Companies, and the SDTM (Submission Data Model)
Other standards are Lab (exchange of laboratory data), CRT-DDS (or define.xml) and ADaM (Analysis Dataset Model).
The ODM, Lab and CRT-DDS standards are written in XML
These products are complementary to the consultancy services we deliver to sponsors, CROs, Data Management Companies, and Clinical Technology Vendors.
The software application to design and develop clinical studies in CDISC ODM format, and to generate and design CDISC Define.xml files

Automatic generation of eCRFs directly from the CDISC ODM
SDTM-ETLTM is a very user-friendly, visual software package to design and create mappings between CDISC ODM and CDISC SDTM,
and to execute these mappings on your clinical data, generating SDTM datasets.
The software also allows to create an SDTM database in which the generated SDTM records can be stored.
Furthermore, the corresponding define.xml file is generated simultaneously.

The CDISC ODM Study and Define.xml Designer v. 2016 is a tool to design and develop clinical studies in CDISC ODM format and to generate and design define.xml files. It reads the ODM XML-Schema or a Vendor Extension XML-Schema, and generates all tables, dialogs and wizards from that. The tool is extremely user-friendly: the user never needs to see any XML. The tool connects ODM and define.xml with SDTM: it knows everything about SDTM domains and variables of SDS 1.1 to 1.4 (SDTM-IG 3.1.1 to 3.2).

The Define-XML Standard
is one of the most established standards of CDISC, and also one of the most important, as it is required to be submitted by regulatory authorities such as the FDA and the PMDA.
The CDISC Define.xml Checker is a software package to validate your define.xml files against the standard and for internal consistency.
The software has been developed by Jozef Aerts, one of the main developers of both the define.xml 1.0 as 2.0 standard, and one of the most knowledgeable people concerning the Define-XML standard in the world.
It uses XML-Schema and Schematron (an "open rule" validation language) - the user can even switch on and off rule separately.
The software has been shown to be much better that the validator that is normally used by the FDA and PMDA (the latter reporting very many false positives).
As such, it is an indispensable software package for every sponsor that is submitting information to the FDA and PMDA using the define.xml standard, also as it allows to distinguish real conformity problems from false positive errors generated by the FDA and PMDA tools.

The ODM Viewer is the first tool on the market to visualize CDISC ODM 1.2 or 1.3/1.3.1 files in a very user-friendly way.
The data are visualized as HTML tables with easy navigation through the whole contents of the ODM file.
The ODM Viewer also allows to tabulate subsets of the data, e.g. all Demographics data of Subjects 1, 3, 7-10 where the Investigator was Jane Doe.

The ODM Generator is a utility tool to transform "flat" data files (CSV, bar-delimited data files, exports from Excel, ...)
into CDISC ODM files, including the generation of the metadata.
It is especially useful in combination with the SDTM-ETL software when part of the data (such as lab data) is not available as CDISC ODM files.
More about the ODM Generator
The CDISC ODM Checker takes a CDISC ODM file and checks it for well-formedness and validity against the DTD or XML-Schema
and (even more important) against the published standard (features that could not be incorporated into the DTD or Schema).
This includes checking for consistency of the data (e.g. ClinicalData against Study MetaData).
If a violation against the standard is found, the application explains in well understandable language what is wrong, and gives good suggestions for reparing the violation.
This application is available for free to CDISC members.
It can also be made available as a module for incorporation into other software (on commercial basis).

This tool allows to transform CDISC Lab files in bar-delimited ASCII format into CDISC-Lab XML format. As such, this tools allows CROs that obtain Lab files in ASCII format to convert it into a better machine-readable format, and then to transform the Lab data into ODM format, and/or to store the Lab data in native XML databases.

The CDISC Lab Checker is a tool for checking CDISC Lab files, either in XML format or in ASCII format, against the standard.
Both these tools have been implemented as server-side tools (you can already use them free-of-charge at our application server), but they can also be made available as standalone applications (as Java application or Windows executable).
The XML version of the CDISCLabChecker has already been implemented at one of our NorthAmerican customers: it allows checking of all CDISC Lab files that are located on the server, and generates a validation report, and a log report (for 21CFR-11 reasons) for each of them. This ensures them that they really work CDISC-compliant.
More details about their implementation will soon be published.
This is a tool for on-the-fly generation of reports (in PDF) format from an ODM file.
The user can select which items of the ODM will be included in the output PDF file. Examples of generated reports of an early version of this reporting system can be found on our web page about "transforming XML data into PDF presentation".

Do you need another tool for working with the CDISC set of standards ?
We have an enormous amount of experience with the CDISC ODM standard, and a good amount of experience with the XML implementation of the Lab standard. Furthermore, we are very experienced in designing and developing software for working with XML, mostly in Java, but also in Perl (CGI), PHP, C++.
So, if you need a tool to work with CDISC standards, or need advice for developing such tools or systems, do not hesitate to contact us.
