About Cytel

Who We Are

The clinical development of drugs and devices is crucial for human welfare. Our mission is to improve success rates in this endeavor.

We do this by improving the design and implementation of clinical trials through the innovative application of statistical science, operations research, and information technology.

What We Do

We provide unrivaled biostatistics and operations research knowledge to our customers. Our knowledge is available in the form of both software and services. This knowledge, supported by our trial implementation capabilities, is what makes us different. We are leaders in the design and implementation of adaptive clinical trials.



Our statistical software for designing every type of trial, including adaptive designs, is the industry standard. We also provide software for supporting Data Monitoring Committees, monitoring patient recruitment, and for implementing adaptive clinical trials.


We provide Strategic Consulting on the statistical design of individual trials as well as development programs. We offer innovative approaches to clinical research. In particular, we are leaders in the design and conduct of adaptive trials. All our customers believe and understand this once they've worked with us.

Our Values and Beliefs

We value excellence in implementation, with an emphasis on obtaining the maximum useful information for the money spent and enabling the best decisions to be made about the candidate drug or device.

We are committed to a collaborative style of working. Clients come to us because they want us to give them our best advice, and not just follow orders. We are not just another CRO.

We are committed to helping our customers uphold the highest standards of scientific rigor, statistical validity, and data quality in all our engagements.

Our customers know it, too.

We take pride that our software for the design and analysis of clinical trials – East®, Compass®, StatXact®, LogXact® - is the industry standard and used also by the FDA. Our products are known for their user-friendliness, detailed manuals, and thorough validation and testing.

We also take pride that our services customers regard us as partners. Our style of working is collaborative, and our goal is to make them successful by being scientific, rigorous, and thoughtful.
