Randomised trials are challenging to conduct and even when well designed, post-randomisation events will occur during follow-up which affect the interpretation of results. For instance, patients may stop taking their allocated treatment and/or withdraw from the study, they may receive rescue medication, or they may die before the outcome can be measured. These issues can pose a challenge to the interpretation of the trial, and are often the source of debate around the validity of results. 

In November 2019, ICH issued an addendum to ICH E9 (R1) (1) entitled Estimands and Sensitivity Analyses in clinical trials to address such issues. In this webinar we will summarise the detail in ICH E9 (R1) (1) and how it impacts clinical development plans.
