### "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).

Openclinica was more complex, had lesser options and was not easy to use for researcher from participationg centers.

### "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.

I can edit without making error and its accessible easily without vpn .

### "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.

### "Intuitive data collection, until the data export"

February 4, 2025

4.0

Positive! 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

### "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

User friend, easy to operate in clinical trial that i have used it so far.

Cons

Have centrally controlled. It is challenging to provide narrations to some slots which are restricted. On the other hand it operate slowly in some of days.

### "Clinical Data Manager"

February 4, 2025

4.0

I like Castor bacause is user friendly for me as Data manager and Site staff.

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.

### "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.

### "Light touch system"

February 18, 2021

4.0

Easy set up for a simple study, including simple sales experience Our biggest headache has been with slowness of the system, though some of that is because hospital IT departments have a "go slow" on any non-critical website. We've solved the issue by providing alternative routes to connect to the internet. However, it is still occasionally reported as being slow to update a page when SDV / sign off being captured.

Pros

Not overly complicated design and user interface for non-drug trials Easy set up, especially of internal data checks Nested forms (records) Visual cleanliness Globally based servers

Cons

Users report it being "clunky" and slow to update pages. This is more noticeable towards the end of the day (don't know if that is numbers of people using the system, or a reflection of having been working on it for several hours) It is not possible to filter on data within reports (as you can with records), nor run queries within the system (to find out how many patients have been diagnosed with a specific condition, captured in a report, I have to extract data for all patients, and clean it up in excel before I can run a simple count/filter function. 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

Hi Helen, Many thanks for your detailed review! Regarding the slowness issue - this is of course not expected behavior - while we have sometimes seen issues with hospital systems using outdated browsers, firewalls or slow networks, it would be good if we can identify the route cause and find a solution. So please reach out to our support team to further investigate this together! In addition, we will be working on improved reporting in the coming period, so stay tuned!

Pros

I like the clear layout and the structure. This type of structure makes my work easier

Cons

I have not found any disadvantages for my field of activity so far

### "What to improve in the castor EDC"

February 4, 2025

5.0

Overall it is a really useful IWRS to work with

Pros

Once inside it is really intuitive. Also, you don't have to change the password every specific time, it doesn't expire and that is really useful.

Cons

Depending in which language you chose, it allows you to log in. It it was in Netherlands it was posible to log in, and if I canged it to english my pasword said incorrect. Also, as a pharmacist I didn't receive an email when the doctor asigned medication on the system.

### "Castor EDC is a good product"

February 4, 2025

5.0

It was intuitive to make use of, and well-designed. It was helpful that a good amount of time was allowed to enter multiple case reports. I would recommend it and make use of it again myself if given the opportunity.

Pros

The site worked well. In particular the survey was well designed to perform real-time quality assessment to promote completion of each section and provide feedback if answers were unclear. If there are any problems, human staff were readily available to resolve them.

Cons

No significant dislike. It might be helpful to have a comment box available for each of the cases reported, in case the person completing the survey has any question about what is being asked for or is not certain that their best response is exactly what is being asked for. Not essential, however.

May 14, 2024

5.0

I really like working with Castor and has made the management of Clinical Trials easier.

Pros

I really like about Castor that it has many different features that can be modified depending on the study, in a more specialized version. It is pretty useful also that all forms are exported together as one, required for the analysis.

Cons

I am really happy with Castor right now.

### "Great EDC system"

May 14, 2024

5.0

Pros

I find the CASTOR EDC very simple and easy to use. The updates that have been implemented haven't disrupted any data collection like some other systems do. The randomisation aspect is always quick and responsive, with no delay for the outcome. I find it to be an intuitive system.

Cons

As mentioned, the randomisation aspect is quick, however since one of the updates the button has now moved to the left of the screen and it just says "not randomised". Until you select this option is may not be obvious that this is how you randomise patients as it looks like a statement, rather than an option to select. A minor fault in an otherwise great system!

### "High-quality, compliant and affordable EDC"

October 26, 2018

5.0

Very positive. It's a compliant, easy to use, intuitive system that is affordable.

Pros

After a quick initial learning curve the system is easy to build out without having someone on staff that is an IT expert. Our clinical study managers are able to build out each study with little to no help from Castor. The database is easy to use by both clinical sites and sponsors. The company continues to improve the features of the system and provide webcasts to review the changes and answer user questions. The value can't be beat. As an early-stage start up company we are happy to have found a high-quality compliant system we can afford.

Cons

The one feature we feel is lacking is the ability of an investigator to "batch approve" once they have reviewed the data. It is labor intensive to approve each study visit and each record generated. Other systems provide this ability and investigator's expect this from all systems.

Dear Lisa, Thank you for the positive review and for outlining all the aspects of our system that we pride ourselves on! We indeed offer regular webinars, help from our support team, and an extensive online manual with the aim that every user creates a database on their own in no time! Bulk actions is a good point, definitely something we are working on (for records, reports, and surveys!). We are also doing a make-over of the entire navigation in Castor in order to improve the design and intuitiveness of the system and to make that learning curve even steeper! Thank you for the 5 stars! Elena Kochova, MD Customer Success Manager

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.

### "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.

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! Best regards, Elena Kochova, MD Customer Success Manager
