In this webinar we give an overview over the statistical optimal design approach in this context. We show how optimal designs can be constructed, covering mainly all-purpose designs (D-optimality) but also more specific designs (c-optimality). We introduce a graphical representation. Next, we show how these concepts can be extended to trials aiming to estimate the interaction between two different substances given simultaneously.

Overview
In practical dose response trials, especially in a cell culture context, experimental designs to establish functional relationships between dose and effect of a substance are generally chosen based on simple rules of thumb. These designs are generally reasonably effective, but not optimal.

Biography
Tim Holland-Letz
Tim Holland-Letz studied Statistics at the Technical University of Dortmund. In 2010, he completed his PhD in the same subject in cooperation with the Department of Mathematics of the Ruhr-University Bochum, focusing on the topic of optimal experimental design. At the same time he was employed at the Department of Medical Informatics and Biometry also at the Ruhr-University, working mainly on clinical studies and general applied statistics in medical research. In 2011, he moved to the Biostatistics Division within the Deutsches Krebsforschungszentrum (DKFZ) in Heidelberg. From this moment on, he has concentrated more on preclinical studies, with a special focus on optimal experimental designs and dose-response analysis. However, he still works on more or less all kinds of statistical problems arising in research and preclinical studies. In 2019 he completed his Habilitation in Medical Biostatistics at the University of Heidelberg.

PSI VisSIG Wonderful Wednesday Webinar Series (2023)
Our monthly webinar explores examples of innovative data visualisations relevant to our day to day work. Each month a new dataset is provided from a clinical trial or other relevant example, and participants are invited to submit a graphic that communicates interesting and relevant characteristics of the data.
An informal event starting with a short talk and then going into breakout rooms to connect with others from the industry. Aimed at those who have recently joined the industry looking to expand their network.
This role is for a senior functional team member supporting Biostatistics activities on assigned Clinical Development, Enterprise Data & Analytics, and QDS projects.
