Webinar Replay - Conducting Sample Size Reassessment with Time-to-event Endpoints
This webinar provides an overview of the SURVIVAL and SURVADAPT modules. Dealing with time-to-event endpoints, this will enable you to increase your sample size when your results look promising but lack the targeted power.
At the end of the webinar you will be able to:
- Use simulation tools to illustrate complex survival data at the design stage
- Explore trade-offs between duration and patient accrual, choice of boundaries, spending functions and hazard functions
- Utilize the promising zone to determine increases in sample size given information acquired during the trial
