Version 5.0.1, Last Modified Date: 4/8/2020

EffTox

This computer program provides a basis for constructing, simulating, and conducting the EffTox phase I-II clinical trial design described in the paper “Dose-finding based on efficacy-toxicity trade-offs”, Thall and Cook, Biometrics 60:684-693,2004 [1]. Please read this paper before using this program, which implements the trial design, simulation, and conduct. Please note that as of version 4.0.0 very important improvements/refinements have been made in two key elements, (1) the prior and (2) the trade-off contour. These are explained in the tutorial, available here and in the computer program.

What's New in Version 5.0.1

  • Adjustment to the trial conduct decision integration parameters

Requirements

  • Windows 10
    (other Windows versions may be compatible but this has not been tested)
  • Administrative permissions may be required to install EffTox depending on the chosen installation location.
  • The following packages will be installed if they or compatible replacements are not present:
    • Microsoft .NET Framework 4.6.1
    • Microsoft Visual C++ 2013 Runtime Libraries (x86)
    • Microsoft Windows Installer 4.5
  • To view the trade-off function details a PDF file viewer (not included with the software) such as Adobe Reader (available for free here) must be installed.
  • To follow the "Send feedback via email" link in the Help -> About EffTox... window, an email client such as Microsoft Outlook (not included with the software) must be installed.

Clift Norris developed the original user interface using C#, C++, and the Microsoft .NET framework version 1.1. Richard Herrick, Clift Norris, Juan Posadas, and John Venier developed the current user interface using C#, C++, and the Microsoft .NET framework version 4.6.1.

John Cook implemented the original simulation kernel using Visual C++. Richard Herrick, Clift Norris, and John Venier modified it.
