Enabling a proactive and real-time approach to trial support

Once a trial is underway, sponsors are often left without a way to monitor performance. They must make a blind judgement call on whether to continue or cancel a trial that has millions of dollars riding on it. At Phesi, we ensure you don’t have to wait until a study is at risk of failing before you take action. Our experts enable you to adopt a proactive and real-time approach – by evaluating and tracking site performance, providing continuous competitive insights, forecasting enrollment rates and cycle times, and advising on possible adjustments based on live data analytics.

We have decades of experience working with the largest sponsors and CROs. We help organizations to rescue missed opportunities in underperforming trials, as well as enhance ROI using forecasted performance data.

    Customer experience

    Phesi worked with us to show that a particular adaptive trial design would give the best performance. The result was a significantly quicker and cheaper devel­opment time on this priority asset.


    Phesi is on the frontiers of defining clinical development as a science, performing systematic analysis of the clinical trial, clinical protocol, and clinical site space to form hypotheses about what will work and what will not. Through observation and experiment you are applying those learnings to inform new clinical programs or save old ones. Phesi is more than the sum of its parts and the value is in the integration.


    Every global R&D leader should know about this and should be testing it within their portfolio.
