Trial Simulator Engine: Available January 2018

Testing Clinical Drug Trial “What-if” Scenarios

Certara’a Trial Simulator Engine is a tool with a command-line interface that helps determine the effects of variability in drug and subject characteristics on the likelihood of trial success. It supports all trial designs using Phoenix Modeling Language (PML), a simple and flexible programming language. With Trial Simulator Engine, users can:

  • Test trial designs against expected drug and subject characteristics to predict the probability of success
  • Compare trial designs across a range of assumptions for dosing schemes, trial sizes, drug potency, subject recruitment, and disease severity
  • Determine the range of possible trial outcomes


Minimize risks and guide decision making
Trial Simulator Engine helps quantify uncertainties about the drug and upcoming trials.

Improve efficiency
Compare potential trial designs that cannot be tested clinically, understand the likelihood of success of different designs, and answer “what if” questions.

Design more informative clinical trials
Trial Simulator Engine helps anticipate risks and preview the range of expected results before committing to further development of a drug and exposing human subjects to experimental therapies.


  • Define and test interactive drug models
  • Perform statistical and sensitivity analysis through graphical and statistical summaries
  • Test the impact on trial outcomes on changes in known information, assumptions about the drug and subject characteristics, and variations in the trial design
