We use CastorEDC for clinical trial data management. It's been great working with Castor, and their customer service always responds so promptly and is always super helpful.

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

There are still some minor bugs that the developers are fixing. Downloading large sets of data can be a bit slow and also delayed.

I am very satisfied with Castor EDC

It’s very easy to create an eCRF and also to monitor studies. GCP compliance is also an important aspect

Probably the ePRO module; questionnaire scheduling can be improved

I use castor to enter data of a clinical trial. It works much fast than most databases and adding comments is really easy.

It is fast and the lay-out and structure of the site works well. It is also easy to add notes and commentary if necessary

It isn't super intuitive. I made a few mistakes the first time I used it. But you learn from your mistakes and afterwards its easy to use.

I use Castor for two studies, one of which is a long-term multicentre study. I have designed these studies in Castor and am very happy with the product.

Castor is easy to use. In designing studies, I like how variables and answers are easily created, and that answers can be re-used for multiple variables. I also really appreciate the feature to have a variable depend on a (hidden) calculation. In using that feature, I have found that https://www.castoredc.com/tools/calculation-helper/ is a great way of testing your calculations are syntactically correct. It is also helpful that additional information can be given per variable. All these and other features make data entry clear and understandable for users, which in turn ensures that data entry mistakes are minimised or even prevented. Furthermore, it helps each study with an audit trail, so that changes are clearly documented for audit purposes. In my contact with customer support I have found that they responded swiftly and were always able to help me with any queries. Lastly, Castor keeps improving on its exisiting product, which to me is a significant sign of long-term viability. This is especially relevant when considering Castor for long-term research projects.

Getting to know Castor takes a bit of time, but it is very helpful to be aware of the structure of Castor, which allows you to fully utilise its potential.
