Group Sequential Designs were one of the earliest deviations from a traditional two-arm clinical trial with no interim looks at the data. They still add amazing value to trials through their abilities to safeguard patients, reach positive conclusions early and keep trial designs simple and streamlined. Sample Size Re-estimation is another key tool in the modern trial designer’s toolkit.

Join us for a complimentary webinar to learn:

  • the basics of Group Sequential Designs and Sample Size Re-estimation
  • how they are used
  • how they can improve trial design

Meet the Speaker

Christopher Jennison is Professor of Statistics at the University of Bath, UK. His PhD research at Cornell University concerned the sequential analysis of clinical trials and he has continued to work in this area for over 35 years. His book with Professor Bruce Turnbull, "Group Sequential Methods with Applications to Clinical Trials", is a standard text on this topic and is widely used by practicing statisticians. More recently, he has written with a variety of co-authors on adaptive trial design and over-arching optimization of the drug development process.

Professor Jennison's research is informed by experience of clinical trial analysis at the Dana Farber Cancer Institute, Boston and a broad range of consultancy with Pharmaceutical companies.
