Sample Size, Power, and Adaptive Trial Design for Late Stage Studies: A Practical Hands-on Workshop

​​The purpose of our workshop at PSI 2017 is to first better familiarize attendees with the underlying statistical methods, then instruct you on designing related trials of greatest interest to you and your organization. Case studies of actual adaptive trials will both illustrate the use of the methodologies and serve as hands-on design examples.

Over the course of 25 years, East® has become an industry standard platform for planning and monitoring early and later stage clinical trials. You do not have to be an East user to benefit from the workshop, but the trial design examples will use the software (provided to all who bring a PC laptop).

Part One
We begin with a trial design and software capabilities overview including:
- Sample size and power calculations
- Adjustments for multiple comparisons
- Early stopping for efficacy/futility
- Sample size re-estimation
- Adaptive dose selection
- Survival endpoints
- Enrollment/event forecasting

Part Two
In the workshop's second part attendees can work through hands-on exercises using the software.

Prepared examples covering many of the stated topics will be provided, with attendees choosing which to work on. Our instruction team will coach attendees throughout the design process, including running simulations to predict likely outcomes.

​2017 Workshop Instructors: Pantellis Vlachos and Yannis Jemiai

​Additional Benefits
​All registrants will receive the complete and latest version of East® to use for 30 days following the workshop.

Refreshments will be provided gratis.

  • Estimating Sample Sizes in Clinical Trials - Dates: 28 – 29 Jun, 2017

    The three most important aspects of a clinical trial are: design, design and design. A sample size estimate is just one aspect of a clinical study design. The course describes calculations for sample size estimation in the design of clinical trials. It will be highlighted how the objectives of a clinical trial will impact on sample size calculations. The course is a practical course and all methods will be illustrated with examples and case studies.
