Castor EDC

Web-based

Sr CRA

Overall experience with Castor is extremely positive. I think the customer support has been great and I really enjoy the company.

Clinical Research Associate

Easy data download process, great interface, and very affordable compared to the other EDC systems out there.

Research Coordinator

Very positive and would definitely recommend if given the opportunity.

Patients manager

It offers a wide variety of tools to validate data entry. It's cost-effective and the fact that one can practice and customize and test before the "go live" is a great advantage.

Clinical Project Manager

The tool was easy to learn thanks to a few, short instructional tutorials and a great FAQ.

Clinical research coordinator

Very user friendly, easy access to online help (email), audit trail available, ease of uploading documents, data editing easily without having to unlock pages constantly.

PhD Candidate

Castor is very user friendly and I loved working with it.

PhD candidate

The structure is intuïtive, solid and runs smoothly which is very important for multicenter research. It helped me significantly in my work as project manager of an international multicenter RCT.

I enjoyed the great level of control when building forms, and even managed to do some coding - and to test that code to make sure it really worked.

There are a lot of features and I would not change anything. The Castor helpdesk was very helpful and responded very quickly when I needed help.

Bio Medical Engineer

The randomization is only in blocks and there is no other options for randomization which is a little problematic with a small group trials.

Program Director

Ease of setup, ease of use and overall has all the functionalities we need for clinical trials.

Clinical Research Assistant

For advanced users, there is no accessibility to more powerfull programming to manipulate the platform. The image/file upload feature is very restricted in file size.

Some building blocks are a bit limited in how they can be used. For example, some can't be set as "required", so one has to create additional fields to achieve the same result.

Overall the system is good, it does it's job and worth the cost. I think simplifying the building proccess and making repeated measures display a bit more informative would be better.

Clinical Research Director

The stats page doesn't allow scrolling, which means I often loose half the information. User experience of using the system across different smart phones is variable.

EDGE

Information Analyst & EDGE Champion

It has been an amazing experience being in it from the beginning nearly, seeing it grow and flourish. Having the chance to input your own requests for change and see these implemented.

Senior Clinical Trials Pharmacy Assistant

This is a great idea and brings to the forefront the ideology of one NHS promoting best practice through sharing best practice. Support team are absolutely great.

Clinical Governance Advisor

The support of the EDGE team is also fantastic, which enhances the overall experience and ease of using the system.

Information & Finance Officer

The beauty of EDGE is the ability to customise it into a bespoke system to meet our own individual business needs.

R&D Coordinator

EDGE is a good company who we have had positive interactions with. When escalation is required to EDGE they are quick to get back to you and offer support via regional contacts if required.

Research Development & Innovation manager

It encourages innovation and collaboration amongst the research community and its development is very much driven by the users. It is very adaptable and easy to use.

Research Governance Lead

The calendar functionality is very basic which makes tracking things difficult. No search functionality on the documents sections make finding things difficult.

The system is intuitive and easy to use with an easy to navigate site and simple but effective easy to follow GUI.

R and I Administrator

EDGE has been my departments life saver, it has improved and aligned nearly all our processes. Could not recommend it enough.

Information Officer

Very proactive team who are always moving forward with the functionality of Edge. The helpdesk is always available and ready to answer any questions or offer help and advise on functionality.

Local Portfolio Management Systems Mgr

The new Knowledge-Base with the inclusion of quick guides for all the topics with real examples and tips has got a very positive acceptance among our users.

The audit reports are difficult to understand and track. Additionally, search functionality instead of scrolling through pages to find a user.

Operations Manager

There are many ways (almost too many) to navigate the system, which can make it hard for new users to learn/grasp.

There are some areas where we would prefer tailor-made restricted access.

Research Manager

All research facing staff involved in study set-up use Edge as part of the process to review capacity and capability. We have plans to extend to clinicians acting as Chief and Principal Investigators.

Network Coordinator

We also give EDGE access to our investigators so they can look up protocols and regulatory documents, as well as our active and upcoming trials by disease site.
