Statistical Analysis of the Comet assay
Research and Clinical Sciences Statistics, Bayer AG, Berlin, Germany
The single cell gel electrophoresis assay, also known as Comet assay, is a widespread test within genetic toxicology and sensitive to detect chemically induced DNA damages in various tissues. This webinar will start with an introduction to the toxicological background and the test principle itself, including a description of the standard experimental design. Different statistical strategies will then be presented; the focus will be on the in-vivo Comet assay. Finally, the use of median instead of average tail intensities per slide will be described and discussed; this is suggested in the updated OECD Guideline for the Testing of Chemicals No. 489, thus directly affecting the statistical analysis.

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.
Talks from speakers will cover an introduction to HTA and indirect comparisons for value assessment before focusing in more specifically on topics related to the use of indirect treatment comparisons for patient access.
Talks from the speakers will cover the use of R in a programming community, submitted to regulators using R, and also programming beyond R in C++ and Julia.
This course is aimed at clinical trial statisticians who are new to or with limited experience of machine learning. Attendees will learn about a range of topics in machine learning, including practical sessions in R.
This webinar will explore two different approaches to Correlates of Protection in vaccine development.
The event will open with an overview on drug development in women’s health from a clinician perspective. This talk is followed by talks about statistical challenges when planning IVF studies and analysing the menstrual cycles.
This webinar will provide an overview of surrogacy for licensing and reimbursement. In turn, the need of extensions of the SPIRIT and CONSORT statement will be defined and outlined, with case studies to support.
This networking event is aimed at statisticians that are new to the pharmaceutical industry who wish to meet colleagues from different companies and backgrounds.
