Webinar held jointly with the PSI on the topical subject of ‘Estimands’

Estimands (what is to be estimated) is a new and hot topic in clinical development, in particular with the regulatory authorities who are responsible for approving new treatments. New regulatory guidance will be developed that will also address the subject of sensitivity analyses. This webinar will explore the current thinking on the topic and revisit some of the earlier work to consider how the topic has evolved over 10 years and how it might look in the future.

Chaired by Andy Garrett.

Abstract:

The topic of estimands is an important and relatively new one in clinical development. Estimands bridge the gap between study objectives and statistical methods. When defining estimands an iterative process linking trial objectives, estimands, trial design, statistical and sensitivity analysis needs to be established. Clinical trials are multi-faceted and expensive. Subsequently it is unrealistic to restrict a study to a single estimand. The set of estimands for a study will depend on the study objectives, the disease setting and the needs of the various stakeholders.
