Estimands and their Implications on Clinical Studies

August 4, 2020

Last year, Paul Terrill, Associate Principal of Strategic Consulting at Cytel, presented an engaging webinar on the topic of Estimands. The webinar covered a range of issues from what is an estimand to how to structure early discussions on estimands. On popular demand, Paul will re-run this webinar on August 13, 2020, and add recent developments on this topic. He will share the bottom-line on estimands and discuss their implications for a trial's objectives, design, data collection, statistical analyses and conclusions. Paul will also share his guidance on managing the communication about estimands between multiple internal stakeholders, gaining internal buy-in, and ensuring that a trial’s objectives, design, conduct, analysis and interpretation are in line with the addendum.

Webinar: Group Sequential Designs and Sample Size Re-estimation

June 10, 2020

Cytel is conducting a webinar series that introduces biostatisticians to some of the more commonly used complex innovative trial designs. Our second webinar from this series was held on June 3, 2020, with Professor Christopher Jennison. Professor Jennison spoke about the modern uses of Group Sequential Designs and Sample Size Re-estimation. 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.

Cytel also did an interview with Professor Jennison where he spoke to us about these methods, their origin and how they add value to the industry. Continue reading this blog for a summary of the webinar. Click on the button below to access the webinar replay and download the presentation slides.
