Confirmatory Adaptive Clinical Trial Design, Simulation, and Analysis.
- Sample size and power calculation for
- means (continuous endpoint)
- rates (binary endpoint)
- survival trials with
- piecewise accrual time and intensity
- piecewise exponential survival time
- survival times that follow a Weibull distribution
- Fixed sample design and designs with interim analysis stages
- Simulation tool for means, rates, and survival data
- Assessment of adaptive sample size/event number recalculations based on conditional power
- Assessment of treatment selection strategies in multi-arm trials
- Adaptive analysis of means, rates, and survival data
- Adaptive designs and analysis for multi-arm trials
- Adaptive analysis and simulation tools for enrichment design testing means, rates, and hazard ratios
- Automatic boundary recalculations during the trial for analysis with alpha spending approach, including under- and over-running
