Employing the best EDC solutions for your clinical Trials

In today’s competitive drug and device development environment critical decisions need to be supported by near real-time data collected through a validated and 21 CFR Part 11 compliant Electronic Data Capture (EDC) system. Our personnel have over 20 years of EDC experience and have designed, built and implemented high quality databases in multiple platforms for hundreds of studies. We are able to bring this experience to your project to tailor a system that suits the specific needs of your protocol, to ensure the data are accurately and rapidly collected and distributed to support findings and allow for informed decisions. We use leading technology platforms to provide our customers the efficiencies available through this technology, improving data access and productivity while reducing paper cluttering and cycle time. At Cd3 we have experience in the development and use of multiple EDC platforms and we are able to provide services as needed. We employ a modular approach to EDC and can support any of your clinical trial needs from full service to selected tasks.

EDC Selection

Cd3 has experience in the selection and validation of EDC systems. Our personnel have chair a global EDC selection initiative for a large pharma company, which included the review of over 70 tool, multiple pilots, selection and organizational restructuring to obtain the largest benefit possible. This selection process was discussed in a 2005 IBM article and it has proven successful ever since. When developing an EDC plan for your research project, we consider all aspects from system setup, data collection, system updates, and archival of study data. This will ensure that the data collected today will be of the highest quality and usable in a regulatory submission for the duration of the entire program and beyond.

Medical Coding

Glossary Coding

An important requirement of analyzing any data is the ability to meaningfully group the records. In the case of Adverse Events, Medical History, or Concomitant Medications, a sponsor must use an ICH authorized glossary. Per license agreements for these glossaries any company that needs to use the coded data, must have a current license. Cd3 maintains current licenses for both MedDRA and Who DD Enhanced glossaries. Cd3 works with your clinical team in assisting with establishing glossary coding conventions and performing study term coding. We are able to support all of your coding needs, from assigning the codes to utilizing them in the production of meaningful tables, listings and graphs. In addition to employing (CodexQ), a proprietary coding algorithm and synonym lists, Cd3 performs manual coding using a two coder process. This helps ensure that the codes selected are appropriate and accurate ultimately minimizing your medical review timelines.

MedDRA Glossary Coding

MedDRA (Medical Dictionary for Regulatory Activities) is a medically valid glossary for use in the regulatory environment developed by the International Conference on Harmonization (ICH). Cd3 maintains a license for the current version of MedDRA and is capable of coding on a bi-term or patient-term basis. We can support various scenarios for coding in-house, at the sponsor, or a third party coding group. We can transfer coding related data and queries in many different formats.

Who DD Glossary Coding

The WHO Drug Dictionary is used by pharmaceutical companies and drug regulatory authorities for identifying drug names, active ingredients and therapeutic use, in the course of drug safety surveillance. Cd3 is able to provide Who DD coding services based on a by-term or by term-indication basis, whichever the sponsor requests. We also support coding by sponsor standard, transferring the terms and queries as SAS or Excel files.

CTC Coding

NCI's Common Terminology Criteria for Adverse Events (CTCAE v4.0) published in May 2009 by CTEP is a list of adverse event terms associated with a severity grading scale. CTCAE v4.0 is used within the oncology research community as the standard for documentation and analysis of AEs occurring in cancer research; for defining protocol parameters such as maximum tolerated dose, dose modification, and for comparison of safety profiles between interventions. Since the adoption of MedDRA by the ICH, the NCI, industry and regulatory bodies identified a need for CTCAE revision and synchronization with MedDRA. In version 4.0, all adverse event terms will be single concept MedDRA terms. These changes have been made in order to increase the accuracy of adverse event reporting and the usability of the terminology set.

Clinical Study Programing with SAS

SAS is a “de facto” standard in the industry. When performing either an EDC or a paper based study with Cd3, SAS output is a standard deliverable. The data that is delivered back to your organization can be structured with SAS formats, labels, and other attributes to make the analysis, reporting, and pooling of the data as easy as possible. Cd3 has SAS programmers who are experienced in supporting clinical studies. They are familiar with working in a regulated environment and able to react to the emerging standards in the pharmaceutical industry.. Cd3 hosts its own SAS server which is properly scaled to handle even the largest studies.

Databases and Derived (calculated) variables

After the data is collected, entered, and cleaned, you need to create an analysis database. This database should be structured to support analysis of your clinical study data. This step requires the ability to program, validate, and document calculated variables, derived from complex algorithms discussed in the protocol, SAP, or from interactions from the study statistician. We can provide these to our clients as SAS transport files and many other formats.

Tables, Listings, and Graphs

When performing an EDC or a paper based study with Cd3, SAS output is a standard deliverable. The data that is delivered back to your organization can be structured with SAS formats, labels, and other attributes to make the analysis, reporting, and pooling of the data as easy as possible.

Incorporating External Data

No Study is complete until all of the data collected is brought together. The external data (non CRF data) needs to be incorporated with the main CRF data. Cd3 can combine the data into a single database, simplifying statistical analysis, and helping your organization to easily retrieve all of the data for regulatory submissions. Without proper planning the external data will be hard to combine with the CRF data due to disparate keys. Cd3 can coordinate this effort and ensure all data points can be related to each other.

Data Standards

Data Standards Development

Clinical Data Standards allow you to maximize the usability of your study data by enhancing collection, analysis, and reporting, improving safety monitoring, and ultimately streamlining the review and approval process for new investigational treatments. Under the ICH’s (International Conference on Harmonisation) guidance on electronic Common Technical Document (eCTD), CDISC Study Data Tabulation Model (SDTM) is the preferred standard for content format and structure of clinical data. A standardized clinical database supports efficient analysis and easy formatting to support your submissions in addition, standardizing your clinical study data reduce costs and Increase operational efficiency by automating repeatable tasks, minimizing writing and validation of code as well as re-programming of tables, listings and graphs for future studies.

CDISC Standard Support

The Clinical Data Interchange Standards Consortium (CDISC) is a neutral, platform independent organization that has been working since 1997 to develop global data standards that enable information system interoperability to improve medical research and healthcare. Cd3 understanding of current industry data standards ensures the appropriate standard is implemented from the beginning, and has the experience to transform metadata and produce compliant deliverables for your existing studies, reducing queries and delays, expediting reviews and ultimately improving you chance to successful submissions Our services include:

• CDASH Compliant Case Report Forms (Paper and Electronic)
• CDASH and SDTM Annotated Case Report Forms
• Data Compliance consulting
• SDTM Compliant Data
• ADaM Compliant Data
• Metadata and Data Repositories
• Comprehensive Quality Assurance
• Legacy Data Conversion and Harmonization

Cd3 has adopted the CDISC standards. All client database deliverables will be provided using this format unless otherwise requested. This will allow our clients to be ready for the next phases of clinical study development. Cd3 have created over 700+ SDTM and ADaM datasets, 570 have already been submitted and reviewed by the FDA. This experience allows us to format your data into CDISC layouts which will help with data reviews for due diligence all the way to regulatory approvals.

Beyond Individual Studies - Creating Safety and Efficacy pools

The development of your compound can be stopped at many points along the development timeline. When it gets a green light to proceed, the ability to make the next step easier will help in shortening the time it takes to prepare your submission. You can better evaluate your compound by integrating the individual study data together as well as save valuable time during the submission scramble by the standardization and pooling of your studies.

Cd3 can assist your efforts by:

• Creating a Data warehouse for you compound as each study is completed
• Migrating already completed studies into a Data warehouse
• Programming Integrated tables and graphs based on the data warehouse
• Converting a Data warehouse into a CDISC compliant structure

Central Randomization

Randomization ensures that each patient have an equal chance of receiving the treatments studied, minimizes variability of the evaluation by avoiding confounding factors and provides a basis for the statistical methods used in analyzing data. Several methods can be used to assign treatments at random, and the choice of the most appropriate method must be carefully considered before the trial is initiated.Cd3 extensive expertise can help you choose the most appropriate randomization method.
