This clinical trial simulation (CTS) program allows users to explore various trial designs and potential issues. It helps researchers understand how different factors impact study outcomes, improving clinical trial planning.

Area of Science:

  • Clinical Trials
  • Biostatistics
  • Medical Informatics

Background:

  • Clinical trial design involves complex decisions with potential impacts on study validity.
  • Simulating trial scenarios can aid in understanding these impacts and optimizing designs.

Purpose of the Study:

  • To introduce an interactive clinical trial simulation (CTS) program.
  • To provide a tool for exploring the effects of various design parameters and methodological problems in clinical trials.

Main Methods:

  • The CTS program simulates trials with two treatment groups and binary outcomes.
  • It incorporates features such as prognostic subgroups, randomization methods, patient allocation, hypotheses, common methodological problems (e.g., non-compliance, dropouts), and analysis methods.
  • Users can input current trial data to estimate future power.

Main Results:

  • The program offers continuous graphical and numerical output during simulations.
  • Thousands of simulations for a specified scenario can be executed in approximately 5 minutes.
  • This enables rapid exploration of diverse clinical trial scenarios.

Conclusions:

  • The CTS program facilitates interactive exploration of clinical trial designs and potential challenges.
  • It serves as a valuable educational and planning tool for students and clinical investigators.
  • The software enhances the understanding of factors influencing clinical trial outcomes.
