Short Course Half Day
Room: Salon A,Salon B
As medical research continues to push into new frontiers of discovery and personalized patient care, along with new complex diseases and worldwide pandemics (COVID-19), new clinical trial designs and statistical methodologies are emerging to impact global public health. One key innovation is the master protocol, in which adaptive "platform" trial designs can evaluate multiple therapies simultaneously under a common protocol. To better direct the discussion, we will focus on adaptive platform trials that have been designed, operationalized, and have released results for select interventions: This includes the HEALEY ALS platform trial for Amyotrophic Lateral Sclerosis, the GBM-AGILE platform trial for Glioblastoma (GBM), the ACTIV platform trials for COVID-19, and the PrecISE platform trial for severe asthma. These platform trials have all been implemented under an IND with extensive regulatory interactions. Having been deeply involved in the design, implementation, and releasing of results for select interventions from these platform trials, the instructors will focus on lessons learned in the design and implementation of master protocol trials. This includes 1) statistical properties & efficiencies of trial design; 2) master protocol structure; 3) logistical and operational challenges; 4) regulatory concerns and interactions; 5) challenges in the release of results with an ongoing (perpetual) platform trial.
Upon completion of the course, participants will have a general understanding of Bayesian adaptive platform trials in both design and practice, including regulatory and pragmatic considerations. They will gain appreciation for the purpose, flexibility, and complexity of the master protocol, and understand key aspects of design and implementation that need to be addressed to achieve a successful trial.

Instructors’ Short Bios:
Ben Saville, PhD, is a Director & Senior Statistical Scientist for Berry Consultants, where he specializes in the design of innovative Bayesian adaptive clinical trials. He works primarily with medical device companies, pharmaceutical companies, and academic investigators to solve challenging problems via Bayesian designs, many of which are reviewed by the U.S. Food and Drug Administration (FDA). He has designed Bayesian clinical trials in a variety of therapeutic areas, including cardiovascular diseases, rare and progressive diseases, infectious diseases, traumatic brain injury, respiratory and digestive disorders, and neurological diseases. Dr. Saville is a frequent invited speaker at statistical conferences, academic seminars, and lecture series, including short courses on Bayesian adaptive clinical trial design. He earned his Ph.D. in Biostatistics from the University of North Carolina at Chapel Hill in 2008 and was an Assistant Professor of Biostatistics at Vanderbilt University from 2008-2014. Dr. Saville has authored approximately 100 peer-reviewed publications in the statistical and medical literature, with expertise in Bayesian hierarchical models and Bayesian adaptive platform trial designs.
Anna McGlothlin, PhD is a Director and Senior Statistical Scientist for Berry Consultants where she leads statistical design and implementation teams for adaptive and Bayesian clinical trials, with specific expertise in the execution of adaptive platform trials. Dr. McGlothlin has designed dozens of clinical trials, providing statistical support that includes extensive simulations as well as consulting on interactions with regulators. Dr. McGlothlin has participated in the execution of > 25 adaptive clinical trials, focusing on interim analyses and interactions with data and safety monitoring boards.
