Monthly Seminar: Beginners guide to adaptive and platform clinical trials
This month's Biostatistics seminar will be presented by Professor Robert Ware who leads the Griffith Biostatistics Unit at Griffith University. He has expertise in statistical inference, clinical trial design and data linkage studies. He has over 20 years' experience as an academic biostatistician and has co-authored more than 450 manuscripts. He collaborates with Griffith colleagues on biomedical, clinical and public health projects.
Seminar Overview
The popularity of adaptive and platform trials has increased markedly in recent years. Adaptive designs can make clinical trials more flexible by utilising results accumulating within the trial to modify the trials’ course in accordance with pre-specified rules. These trials are often more efficient, informative and ethical than trials with a traditional fixed design since they can often be completed more quickly and at lower cost. Platform trials can study multiple interventions for the same disease, with new interventions added, assessed and removed as the trial progresses. This seminar will introduce adaptive and platform trials, and discuss their advantages and disadvantages compared to traditional trial designs.
Thursday 18th April from 12:00 - 13:00 in G39_1.16 (Gold Coast campus - Griffith University) and by MS Teams
