Castor EDC in Clinical Trial Data Management **Rating:** 2.5/5.0 stars **Reviewed by:** Suvathi B. | Enterprise (> 1000 emp.) **Reviewed Date:** October 05, 2023 **What do you like best about Castor?** Castor EDC is easy to use and learn quickly. We can contact customer support easily and their response time very quick. Also, the role level permission feature for users is awesome. The email alert and survey feature also helps users in the clinical trial data management. Regarding the queries, it is easy to filter the closed, open, new queries. The EDC also displays the overall graph of study data which is very useful for study level tracking. And, it has separate page for repeating forms which is easy for integration. **What do you dislike about Castor?** The form level export is not possible in Castor EDC. Eventhough, we have options to export data for selected forms, the study export has all the data. The SDV level page in export is not appropriate. It does not show the exact SDV status of each form/field. Also, it does not have audit trial export. 360 degree query report is not possible to export in Castor which is difficult for Data Manager to analyse study data. Also, it does not have feature for DM marking for Data Manager and Safety marking for Medical Monitor. Also, it does not have feature to raise queries to specific role. Single person cannot have two study roles. **What problems is Castor solving and how is that benefiting you?** Clinical Trial Data Management **Official Response from Cole Egan:** > Thank you for taking the time to provide such detailed feedback on Castor EDC. We're delighted to hear about our platform's ease of use, quick support response times and awesome role-level permissions. We acknowledge your concerns about our export functionalities and are excited to update you on our progress. We've been actively working on redesigning our exports (we don't have form level export now, let's stick to our current export) to enable domain-based exporting, and following our June update, SDV has been enhanced to be at field level. We're also in the process of planning an SDV export feature to further streamline your data management activities. In terms of audit-trail exports, we've made significant improvements making it more efficient and now available on-demand for our Professional Services and Customer Support teams. Looking ahead, we are excited to share that in the upcoming year, we will be placing a stronger emphasis on patient-focused developments. Watch this space! Your feedback is essential in guiding our efforts so we are grateful for that. Thank you for your ongoing support. The Castor Team. ### 2.
