PhD candidate Hospital & Health Care Used the software for: 2+ years ### "Good product, best service and easy to use" May 4, 2020 4.0 Pros 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. Cons There are still options for improvement, such as a reminder for participating researchers of a coming deadline for a study visit (but Castor may have added this feature since I last used it). Switched from [OpenClinica](https://www.capterra.com/p/78122/OpenClinica/) Openclinica was more complex, had lesser options and was not easy to use for researcher from participationg centers.

MD Hospital & Health Care Used the software for: 1-2 years ### "Great experience" February 13, 2025 5.0 I’ve been working with several EDC instruments and in Castor I’ve found an all in one tool with randomization, monitoring, high security level data storing, and a great flexibility to customize the eCRF. Pros The flexibility to customize the EDC intrument. Cons It is very expensive for independent researchers in middle income countries (I am from Argentina and after pandemic I couldn’t afford it). Alternatives considered [ODK](https://www.capterra.com/p/264830/ODK/)[RedCap](https://www.capterra.com/p/234600/RedCap/) Reason for choosing Castor EDC During pandemics Castor was free and data storage was cloud-based, so no server was needed. Switched from [OpenVPN Access Server](https://www.capterra.com/p/159435/access-server/) Both were weaker tools and did not have adequate features for clinical trial management.

CRC Health, Wellness and Fitness Used the software for: 1-2 years ### "EDC review about CASTOR 2024" February 11, 2025 2.0 Pros I can edit without making error and its accessible easily without vpn . Cons didn't like it unfortunately since its not user friendly with a lot of repetition and similar texts. Review Source Response from Castor February 21, 2025 Hi Muna, Thank you for your feedback as not everyone takes the time to review. Your input helps us understand our areas of improvement and has an effect on our roadmap. I'd love if you could expand on what was not user friendly so that I can pass it along to the appropriate team. DP David P. Research technician Research Used the software for: 2+ years ### "I would improve a few things in pop-up messages" February 14, 2025 5.0 In general, very useful and recommendable. Pros Castor EDC is very easy to use for filling out forms and sharing the data from those forms with different stakeholders. Cons What I like least about Castor EDC is its pop-up messages asking for a 'reason for change according to GCP practices' whenever I change an answer. I would like to suggest the following improvements: #1 – More time to make changes or the ability to come back and modify them at any time while still filling out the form. #2 – The option to come back and add more answers to a multiple-choice question while still working on the form (this is not a change to an answer but merely an addition of data). #3 – If I complete a form and later modify the contents of more than one question, the messages should be specific to each change rather than general for the entire page, since the reasons for each change might be different.

I feel like every option that exists is there for a reason; so overall the programme feels very intuitive. Pros Overall it's intuitive and if you have a technical question, you can e-mail and will get a quick response. Cons Data export to SPSS: I never succeed and end up doing it in Excel and copying it to SPSS Review Source EP Evita P. Senior Research Nurse Hospital & Health Care Used the software for: 2+ years ### "Castor feedback" February 11, 2025 4.0 I use Castor on a daily basis. I have used multiple databases over the years and although not perfect, so far it is favourite. Pros I like how Castors looks and how easy it is to navigate Cons I don't like that tables are not recognised as being incomplete. Also, I use an Ipad to log in to castor most of the times and I am not sure that when I need to input numbers on multiple fields the keyboard doesn't stay in numbers and I have to constantly swap from letters to numbers.

Pros Easy to use and Navigate. Add new variables. Cons To find out a list of all Notification given to all staff. Sometime you have 10000 notifications and its not easy to find out by exporting to a list. Review Source ZI Zoe I. Senior Research Nurse Study Coordinator Research Used the software for: Less than 6 months ### "Ease of Use" February 18, 2025 4.0 it is great so far. when I enter data it automatically saves. I can see the queries if there are pending. The survey status if patients have not yet completed their surveys. Even the ability to send surveys/questionnaires to patients is very convenient. I can see who last opened the patient's file. The ability to redacted documents that is helpful too. The authentication factor is easy to do, aside from security. Pros Ease of use. The tabs are clearly identified. Cons None so far maybe because this is the first trial we have on this EDC and not a lot of participants and not a lot of information to enter.

This is my first job in data entry and Castor has made it easy. Pros I like how smooth it is to switch to different tabs while working on data collection.

MD PhD candidate Research Used the software for: 2+ years ### "Castor EDC - a reliable and user-friendly solution for clinical research" June 21, 2022 5.0 Castor EDC enables users to perform clinical research in a very efficient way. Castor offers a technological solution that has made data collection, processing, randomisation and data transferring very easy. This is an excellent example of how technology can help to reduce work pressure. Pros It is realible and the helpdesk is excellent. Most important is the fact that collected data can be saved and archieved in a safe way, according to the current standards of regulation. The online platform enables efficient management of participants. The online survey feature is very useful to collect data, where the collected data can be stored directly in the database. Cons Loading of the entry fields sometime takes a while, although this could also be due to a poor internet connection. Review Source MV Medard V. PhD student, resident Internal Medicine Health, Wellness and Fitness Used the software for: 2+ years ### "Castor EDC: perfect for data capturing when performing clinical studies " July 11, 2021 5.0 I used Castor EDC for several medical research projects, to store medical data from hundreds of patients under care at several hospitals. I very much enjoyed working with Castor EDC. The program is now adapted by our hospital as main data capture program. Pros There are many great features about Castor EDC. The most important ones: - The product is extremely easy-to-use; everyone can work with it, the functions of the program are very intuitive. Therefore, the product can be used in clinical trials for data input by different researchers without a intensive and/or long training period. - Castor EDC is very easy to customize to a specific setting; several data structures can be created and different forms of information can be stored. Thanks to this adaptibility, I was able to use Castor for several of my research projects. - data transfer to data-analyzing programs is very easy - Castor customer support is very good; every time I encountered a problem, I got a quick reply and customer support offered handy solutions every time. Cons There are no features that I miss about this program, or things that I would like to see improved. Review Source RB Rachael B. Site Director Research Used the software for: 2+ years ### "Great Flow" May 20, 2024 5.0 I have worked in Castor in 10 different studies and never really encountered a problem Pros Ease of moving from one subject to the next, as well as moving page to page within a subject. Cons There is nothing about Castor that I do not like. Review Source BH Bill H. CEO Biotechnology Used the software for: Less than 6 months ### "Easy to use and well designed" May 2, 2019 5.0 Pros We are a small start-up company and the task of setting up our study fell on me, a person with absolutely no experience with EDC systems. After doing a little research we selected Castor EDC because it seemed easy to use and the price was right for us. Castor EDC has been everything we've hoped it would be. It is easy to learn and set-up. Our study sites have liked it and found it very easy to use. It is feature complete doing everything we have wanted to do. One concern we had was that the company has no US-based support and we are on the West coast. As such, getting support in real-time is really not an option. I was also concerned about possible language barriers. Those initial concerns have not materialized to be realities. On the three occasions I have required support, I have received it within 24 hours, via email. Each time the answer I received was complete and they addressed my question on the first response. Overall, we are very satisfied. Cons I have two fairly nit picky issues: 1. Setting up user rights is a bit clunky. It is very flexible, which I love, but a bit clunky. 2. Dependencies and validations are limited to a single field and the logic is very limited. On the plus side, one can work around those limitations with hidden calculations. Review Source Response from Castor May 3, 2019 Hi Bill, Thank you so much for you review. We are very happy to be able to help your business with such an important element of your journey towards getting Alibrex to market. I will be in touch soon for a personal introduction. Please know, while not immediate, we do plan to redesign the validation and dependency builder. In the mean time, as you mentioned, multi-variate edit checks and dependencies can be scripted using calculation fields. Derk Arts, MD PhD CEO Castor EDC YK Yvonne K. PhD candidate Hospital & Health Care Used the software for: 2+ years ### "Castor for clinical data management" July 4, 2022 5.0 Pros The amount of features for the data collection questions, several forms and options can be selected for different types of data. I have used many of the features to capture different data types. Also the options for randomization and surveys are very useful for clinical trials. Cons For first time users it will be time consuming to make the data collection forms, however once you have the forms you can re-use them for new studies by importing the forms. Review Source SK Sjors K. MD, Research Fellow/PhD Candidate Hospital & Health Care Used the software for: 2+ years ### "Castor is an indispensable tool for clinical research! " January 21, 2019 5.0 I used the platform for 5 international retrospective multi-center cohort studies and it was a great experience to see how researchers at all the participating centers interacted so easily with the software. Everyone loved it. Pros Castor is a GDPR compliant tool to capture and store baseline characteristics, patient surveys, and clinical outcomes. It's affordable, easy to set up and easy to use. What I love most about it is that it improves the study quality so much compared to traditional methods of data capturing. I also love all the automatic calculations (e.g. age from date of birth and procedure date) the system can perform. The ePro feature to send out surveys to patients directly is great! Cons The platform could be even better if it offered functionality to design/structure all variables, definitions, input value options, and calculations in Excel and upload it to Castor. This would make it so much easier to translate (parts) of existing databases to new projects. Also, I missed an option to directly export the database to STATA. Castor currently only supports CSV/Excel/SPSS. Otherwise, no cons. Review Source Response from Castor April 9, 2019 Hi Sjors, Thank you for your positive review! It's good to hear that you have used Castor for so many multicenter studies and that all users were happy with the platform. We hope you conduct many more successful studies in the future! We actually have an internal method to transform existing 'Excel' databases into Castor and we do offer such transformations. Please get in touch and we can lead you through the process!

Study Coordinator Research Used the software for: 6-12 months ### "highly recommended" May 21, 2024 5.0 Pros The application's intuitive interface allows stress-free navigation with functions for efficient study management. Cons I haven't at the moment a different view to criticize the system.
