    This study introduces a new testing method for Phase II clinical trials to assess cancer treatment effectiveness. The procedure allows for early trial termination if results are clearly negative or positive, maintaining trial integrity.

    Area of Science:

    • Clinical Trials Methodology
    • Biostatistics
    • Oncology

    Background:

    • Phase II clinical trials commonly assess antitumor therapeutic efficacy.
    • Ethical considerations necessitate early termination procedures for trials with extreme initial results.
    • Existing methods may not fully preserve the statistical properties of single-stage procedures.

    Purpose of the Study:

    • To propose a novel one-sample multiple testing procedure for Phase II clinical trials.
    • To enable early termination of trials based on interim results.
    • To maintain the statistical size, power, and simplicity of standard single-stage procedures.

    Main Methods:

    • A one-sample multiple testing procedure is developed.
    • The procedure integrates a standard single-stage test at the final stage.

  • The method is designed to allow for early stopping rules.

    • Main Results:

    • The proposed procedure allows for early termination of clinical trials.
    • It effectively preserves the statistical size and power of single-stage tests.
    • The method maintains the operational simplicity of traditional approaches.

    Conclusions:

    • The developed testing procedure offers an ethical and efficient approach for Phase II clinical trials.
    • It provides a robust method for evaluating therapeutic efficacy while allowing for early stopping.
    • This methodology enhances the design of clinical trials by balancing ethical considerations with statistical rigor.
