Version 1.1.0, Last Modified Date: 12/22/2021

Bayesian Optimal Interval (BOIN) Design Desktop Program

The BOIN Design Program provides a novel platform for designing various phase I clinical trials, including single-agent and drug-combination trials, as well as trials with late-onset toxicity. The program allows users to design trials, run simulations, and generate trial protocols in multiple languages (English and Chinese).

Description

The software (i.e., a Windows desktop program called “BOIN”) implements the BOIN designs [1,2] for single-agent trials, single-agent trials with late-onset toxicity [3], drug-combination trials seeking a single MTD [4] or the MTD contour [5]. As a model-assisted design, the BOIN design combines the advantages of algorithm-based designs and the advantages of model-based designs.
It can be implemented in a simple way similar to the traditional algorithm-based 3+3 design, but yields excellent performance comparable to the more complicated model-based designs, such as the continual reassessment method (CRM) [6, 7]. The BOIN design is motivated by the top priority and concern of clinicians, which is to effectively treat patients and minimize the chance of exposing them to subtherapeutic or overly toxic doses.

System Requirements

  • Windows 10 (may work on earlier versions of Windows as well, although this is not supported)
  • Microsoft .NET Framework version 4.7.2
  • Minimum screen resolution 1318x860
    Note: You can still use the program with a smaller screen resolution, but it may require the use of scroll bars. If you have your display set to use a text size of “Medium - 125%” or “Larger - 150%” you may need a greater screen resolution to use the program without scroll bars.

If any required software component is absent from your system, the installation process will install it.

Features

  • Self-contained Windows program
  • Very easy to use
  • Handles single-agent and drug-combination phase I trials
  • Accommodates late-onset toxicity/fast accrual to accelerate phase I trials
  • Automatically generates a protocol document template in both English and now ??!
  • Enables the user to generate operating characteristics for protocol preparation
  • Optionally generates operating characteristics for 3+3 and Rolling 6 trial designs for comparison to the single-agent BOIN and TITE-BOIN designs respectively
  • A Trial Conduct tab for conducting drug-combination trials and estimating the single MTD or MTD contour from trial data

Why use the BOIN Design?

  • Simple to implement  Similar to the 3+3 design, the dose escalation/de-escalation rule is prespecified and can be tabulated. During the trial conduct, clinicians can simply count the number of patients who experience toxicity and compare the observed toxicity rate with the prespecified dose escalation/de-escalation boundaries to determine dose assignment until the trial is completed. For drug-combination trials, the dose escalation/de-escalation rule is the same but the overall conduct of the trial is more complicated which is why we provide a trial conduct tab for those trials. Nevertheless each decision to escalate the dose, de-escalate the dose, or remain at the same dose is easy to understand, explain, and predict.
  • Superior performance  Both theoretically and numerically, it has been shown that the BOIN design has desirable statistical properties and superior operating characteristics [6 , 7].
  • Highly Ethical  The design optimizes the dose assignment for each patient in the sense that it minimizes the chance of assigning a patient to either a subtherapeutic dose or an overly toxic dose. This is consistent with the clinician’s point of view for conducting clinical trials, i.e., maximizing the patient’s treatment benefit.
  • Accommodates both single-agent and drug-combination trials  The BOIN design can be used to design both single-agent and drug-combination phase I trials. The resulting designs are easy to implement.
  • Accommodates late-onset toxicity and fast accrual   The time-to-event BOIN (TITE-BOIN) design allows real-time dose assignment decisions for new patients while some enrolled patients’ toxicity data are still pending, thereby significantly accelerating phase I trials.
  • Solid statistical justifications  The design optimizes a sensible statistical criterion. It has a desirable finite-sample property (i.e., is coherent) and a desirable large-sample property (i.e., converges to the target dose). See the references for more details.

Documentation

Extensive context-specific help is provided in the program itself for all aspects of the trial design and how to use the program. The program produces simulation output which can be incorporated in other documents and also can automatically generate a protocol document template in either Word or HTML format. An extensive statistical tutorial, written for the R package BOIN, is available separately. This tutorial covers the statistical basis of the method, and has guidelines for how to use the method.

What’s New in v1.1.0?

Added an 'Estimate MTD/MTD Contour' tab page for the BOIN COMB designs. Added a (W)STFT [(weighted) standardized total follow-up time] calculator for even easier TITE-BOIN trial conduct. Added the capability of launching multiple simulators of different design types, simultaneously. Various other improvements.
