TRANSCRIPT
Fully validated, SiZ is in use across industry, leading research institutions and international regulatory agencies.
• Design and analyze data by choosing from parametric or p-value based multiple comparison procedures
• Simulate and compare procedures to optimize your testing strategy
• Visualize design operating characteristics to help decide on the best trial options
Design and Analyze Multi-Arm Trials
Multi-Arm Clinical Trials
SiZ® modernizes trial planning for multiple arm studies by combining design, simulation, visual-ization, and data analysis within the Architect™ software standard environment. Trial designers can choose from a wide range of multiple comparison procedures – parametric and p-value based – to optimize the pairwise testing strategy of their fixed sample size design. Study planners can quickly compare design strate-gies using the fast simulation engine. With an array of tables, plots and graphs, SiZ clearly communi-cates trial concepts among study stakeholders.
