Ingram Olkin Forum Series: Unplanned Clinical Trial Disruptions

March 23, 2021 10 am - 1 pm ET, Tuesday

Session Five:  Coping with Information Loss and the Use of Auxiliary Sources of Data

Many clinical trials that were under way in early 2020 have been disrupted by COVID-19. In some studies, it has been possible to adapt by monitoring patients’ progress remotely rather than through in-person visits.  Session Five continues an Ingram Olkin Forum series that started with views from statistics leadership in US NIH and regulatory agencies.  Following these introductory sessions, we focus on particular statistical methodologies that might contribute to statistical responses to unplanned clinical trial disruptions or provided a basis for the development of methods that provide a more appropriate response to this challenge.  Topic specific sessions to date include Estimands and Missing Data and Randomization Tests.  We are pleased to announce Session Five (Please click on the preceding links to catch up with this series).  

In other cases, the continued follow-up of existing patients and recruitment of new patients has not been possible, leading to study termination with a smaller sample size and less complete information on patient response than had been planned. This session will explore methods to overcome this information shortfall. One approach is to use short term endpoints to replace or augment the original endpoint. Another option is to make use of historical data or concurrent data from external sources. Our speakers will describe such approaches and outline the challenges they pose.

Agenda

10:00-10:15 Introduction 

James Rosenberger (NISS Director, Penn State University)
Nancy Flournoy (Chair of the organizing committee, University of Missouri) 
Chris Jennison (Moderator, University of Bath)

10:15-10:45   Nigel Stallard, (Warwick Medical School)

"Using short term endpoint data in interrupted clinical trials"

10:45-11:15   Marc Vandemeulebroecke, (Novartis)

"Mitigating “force majeure” trial disruptions by leveraging external data, with special reference to pooling approaches"

Abstract: The COVID-19 pandemic has disrupted normalcy of life, work and research on a scale that could not be anticipated. Clinical trials in particular have been facing a multitude of issues, up to being stopped prematurely. What could be viable strategies for mitigating this type of   information loss by higher force? In this talk, I touch upon possible approaches that leverage external information. Special attention will be given to pooling approaches inspired by a real case study.

11:15-11:25   Break

11:25-11:55   Heng Li, (FDA, NIH)

Mitigating study power loss in disrupted clinical trials: Leveraging external data via propensity score-integrated approaches

Abstract: Clinical trials may be disrupted by unforeseen events such as the COVID-19 pandemic. We discuss a practical procedure for salvaging those stopped studies for which restarting enrollment is not feasible, by integrating external patients with data already collected to recover the loss of study power due to premature stopping.
