Data Transparency SIG


To share experiences and challenges of external patient level data sharing with particular focus on data privacy and anonymization processes.

Who we are

The Data Transparency SIG is a group of statisticians from industry and academia, with experience and interests in clinical trial data transparency and the associated challenges of patient data anonymization. This includes statistical methods supporting quantitative risk assessment and the privacy aspects of open publication of clinical documents in accordance with evolving regulatory requirements (e.g. EMA Policy 0070, Health Canada and FDA).

  • Webinar: MCP-Mod – Theory, Implementation and Extensions - Dates: 08 – 08 May, 2019

    MCP-Mod (Multiple Comparisons & Modelling) is a popular statistical methodology for model-based design and analysis of dose finding studies. This webinar will describe the theory behind MCP-Mod (plus extensions), and how to implement it within available software. Pantelis Vlachos (Cytel) will provide a brief introduction to the methodology and illustrate the MCP-MoD capabilities in EAST 6.5. Saswati Saha (University of Brehem) will discuss new variations and alternatives to MCP-Mod and show how to implement them in R. Neal Thomas (Pfizer) will present further technical details of MCP-Mod by evaluating the method using results from least squares linear model theory.
