At Castor, we believe in the power of clinical research and the power of technology. And we know that together, these forces can help extend human healthspan. To achieve this reality, we must make patient-centered clinical trials a possibility for everyone, anywhere in the world. That's why we are using technology to capture the world's research data and optimize each activity of a clinical trial. From recruitment to monitoring, our modular clinical trial platform makes it easier to design and deploy trials, enroll and engage patients, collect data and analyze results. Each module can be used individually or in unison with others, providing the ability to customize each solution to fit your needs, and grow at your own pace. That’s delightful for patients, effortless for study teams, risk-free for sponsors.
