A PSI Pre-Conference Training Course

A PSI Pre-Conference Training Course on Subgroup Analysis

Presented by
Aaron Dane, Armin Koch, 
Ilya Lipkovich & Gerd Rosenkranz

It is common to conduct subgroup analyses in clinical trials at all phases of drug development. Consistency of treatment effect across subgroups indicates that the conclusions made regarding treatment benefit are applicable across various baseline characteristics and associated subpopulations, whilst substantial heterogeneity in treatment effect may suggest clinically relevant differential treatment effects across relevant subpopulations. At the extreme, the presence of substantial heterogeneity may imply that the conclusion of beneficial treatment effect is only relevant for a subset of the population. Interpretation of subgroup analyses is challenging as subgroup findings can be due to chance. This is particularly likely when a large number of subgroup analyses are undertaken. Further, clinical trials are generally not powered for detecting heterogeneity, so statistical tests may also miss important interactions due to low power.

EMA issued draft guidance on approaches to subgroup analysis and convened a workshop to discuss this guidance in 2014, with further work ongoing within PSI to explore approaches to analysis that may be acceptable in regulatory submissions, with the aim of having further interactions with regulatory agencies regarding their use.

This course will address the importance of pre-specification, how this can help inform interpretation of apparent subgroup findings, will outline the key concepts from the EMA draft guidance and will introduce approaches to subgroup analysis which account for some the issues described. The course will consist of lectures. There will not be any computer exercises.

The following key topics will Be Covered   
The documents from US and European regulators
The used of bias-adjusted analyses to account for the over-selection inherent when conducting a number of subgroup analyses
The role of subgroup pre-specification and how this can inform the analysis and interpretation process
Presentation of results from Bayesian analyses looking to borrow information across subgroups, or to incorporate prior data and belief into the analysis.

The use of graphical methods to understand subgroup effects in the context of the number of analyses performed

Course runs from:       13:00 – 17:00 on the first day (Sunday) of the conference
