Learn best practices for implementing eCOA in your clinical trials
Castor has been everything we 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 need it to do.
It was easy to create our clinical trial workflow. Integration and training with external partners was effortless. Usability and light coding were essential to us. We were able to test and build our own studies with minimal support and admin.
Castor has been a wonderful partner to work with. Their solution provides us with an integrated eConsent, ePRO, and EDC that's critical in our decentralized studies. The solution is backed by a fantastic support and technical team who's always willing to work with us to find solutions.
Castor's solutions were easy to navigate and intuitive to use, which is why we were interested in working with them. They were able to accommodate the amount of data from our multi-site randomized controlled trial, and our sites have expressed how much they have enjoyed using Castor as well.
It can be difficult to find fit-for-purpose trial solutions for studies that vary in size, complexity and face different budget constraints. We have partnered with Castor because their solution is easy-to-use and easily scales across varying regulatory environments.
Castor offers a truly seamless clinical trial experience for investigators and patients. Fast deployment was critical for us. Castor technology was easy to use and the self-service capability allowed us to deploy a study in just a few weeks.
