Clinical Trial Simulation: Planning With the OCTAVE Framework, Implementation and Validation Principles.

Area of Science:

• Biostatistics
• Clinical Trial Design
• Pharmaceutical Research

Background:

• Complex innovative clinical trial designs are increasingly adopted for improved efficiency, such as reducing sample size or time to findings.
• These designs often feature multiple stages and unconventional elements, presenting challenges in setup, implementation, and computation of statistical properties.

Purpose of the Study:

• To present a new framework, OCTAVE, for detailing clinical trial simulation (CTS).
• To provide practical recommendations for implementing CTS and address computational considerations.
• To enhance the understanding and application of complex innovative clinical trial designs through simulation.

Main Methods:

• The tutorial introduces the OCTAVE framework for outlining CTS specifications.
• It offers practical guidance on the implementation of CTS.
• Key computational aspects relevant to CTS are discussed.

Main Results:

• The OCTAVE framework facilitates the detailed specification and planning of CTS.
• Practical recommendations and computational considerations are provided for effective CTS implementation.
• The tutorial addresses the need for more focus on CTS planning in existing literature.

Conclusions:

• CTS is a valuable tool for optimizing complex innovative clinical trial designs before real-world implementation.
• The OCTAVE framework and practical guidance aim to simplify CTS for trial statisticians.
• This work contributes to a better understanding and utilization of advanced clinical trial methodologies.
