Designing Event-based Studies: Reduce Sample Size and Increase Predictability

Many organizations find it difficult to design event-based studies such as cardiovascular or oncology trials. Understanding how many patients will be needed and how long the trial will take requires advanced statistical approaches. Such complexities make it more difficult or time consuming to optimize the operating characteristics and ensure the trial will meet your organization’s objectives. Join Cytel for an online seminar with industry thought leader Pantelis Vlachos to learn methodologies to overcome these challenges.

This webinar describes advanced techniques that have the potential to help you:

  • Reduce the number of patients and duration required without compromising the validity of your study
  • Be more confident that your interim analyses will be timed appropriately and more easily communicate timeline uncertainty
  • Make more informed decisions about how to proceed given data observed at the interim

Together, these approaches can help you avoid unnecessarily prolonging a study. As a result, you can more confidently set expectations across your organization, make better use of limited R&D resources, improve the experience of your patients, and help them more rapidly access effective therapies.
