Founded in 1987 by Cyrus Mehta and Nitin Patel, research scientists at Harvard University and MIT respectively and collaborators at the Dana Farber Cancer Institute, the early mission was to create software that could expedite oncology trials.

At the time of founding groundbreaking therapies were slow to market due to the time it took to conduct small sample statistical analysis. After successfully launching StatXact® and LogXact® for small, skewed and sparse data, Cytel pioneered East®, which remains the industry standard for advanced trial design.

With a continued focus on efficient trial design that bends the cost and time curves, Cytel has championed group sequential, adaptive designs, population enrichment trials, seamless trials, and methods of program and portfolio optimization.

Our consultants advise on both large-scale and small sample designs across therapeutic areas including those that are biomarker-driven and employ Bayesian methods and we unlock real-world observational data and create opportunities for HEOR and market access.

Our expansive FSP team and project-based services employ world-class biometrics expertise to accelerate high-quality deliverables. Our software team continues to produce a package of products that enable these methods to diffuse across the industry, driving up the probability of success. These include East, Compass, StatXact, LogXact, ACES (for DMC Services), Enforesys for patient recruitment, and from 2020 Solara – a software platform that synthesizes statistics and strategy to help you achieve your development goals.
