About OnCore and EDC

OnCore is GW's Clinical Trial Management System (CTMS). Advarra EDC, which works in conjunction with OnCore, is a validated electronic data capture system; it will be used for investigator-initiated trials. Both systems are created and supported by Advarra and can be accessed through a web browser.

Frequently Asked Questions (FAQs)

Why is the GW Cancer Center using OnCore and EDC?

The GW Cancer Center has chosen to adopt OnCore and EDC in order to make protocol management, subject management and financial management relating to trials more straightforward and transparent. OnCore makes it easy to keep track of all the moving pieces involved throughout the lifecycle of a study. Rather than hunt through multiple spreadsheets to get the answer to a study-related question, investigators can log in to OnCore and access all relevant data in one convenient place. By getting rid of data silos and enabling centralized tracking of trial data, study staff will have a clearer window into how studies at our institution are faring at any given time.

EDC, as a validated system, meets Title 21 CFR Part 11 requirements for the storage of electronic records and signatures. It will allow the GW Cancer Center to store data about investigator-initiated trials in a reliable manner that is in compliance with the above-mentioned requirements set down by the FDA.

When should I use OnCore for my clinical trials?

OnCore will be used for all clinical trials at the GW Cancer Center going forward. Investigator-initiated trials will be entered into EDC, as well, and managed from there (some protocol information will carry over, as EDC is linked to OnCore).

How can I get data out of OnCore for analysis?

OnCore comes with many standard reports in a variety of areas, including Data Table 4 reporting. Users with reporting permissions can run reports and download the results in Excel format for further tweaking. In addition, protocol and subject search pages allow for detailed queries in these areas. EDC has robust reporting capabilities, as well. All data can be exported as an Excel file or SAS dataset. To learn more, see the reporting-related guides in the training library.

OnCore and EDC common troubleshooting questions

Why does OnCore/EDC log me out while I'm entering data?

  • Per security guidelines, OnCore (or EDC) will automatically log you out if the system detects you have been inactive for 10 minutes. Activities that let OnCore know you are actively working include hitting "submit" after entering data or moving to a different page in the console. If data entry is taking longer than you expected, it is best to hit the "submit" button to save your work (do not double-click).

I'm following directions, but when I click on a button in expectation of getting a list of items to choose from, nothing shows up. What's going on?

  • You'll need to disable the popup blocker on your browser in order for OnCore/EDC to work properly. If you have disabled your popup blocker and still aren't seeing what you expect to see, email us at and we can assist.

I'm not seeing the buttons I need to click to move forward with my work. What's going on?

  • You might not have the right permissions to view an "update" or "signoff" button. Get in touch with us at and let us know what's going on; we can update your permissions based on your role.
