Advisory Board, Director of Epidemiology and Real-World Evidence 

Dr Chantal Van Gils

Chantal is a seasoned specialist in real-world research, epidemiology and health economics. She brings extensive knowledge and a wealth of professional experience in harnessing population-specific analyses and quantitative methods to inform both interventional and observational clinical studies including pragmatic trials, natural history of diseases, registry-based data, patient-related outcome reports or multi-dimensional molecular medicine data.

This expertise is critical to inform development and regulatory decision-making along the value chain and product life cycles, based on integrated evidence planning.  

She provides strategic advice and scientific leadership to support clients in clinical development, registration strategy, submission, early post-approval strategy or other health authority interactions for high priority programs and/or non-interventional studies across all therapeutics areas, and notably oncology and ATMP.

Key areas of expertise
  • Real-world study design – all kinds of observational or low-interventional study designs using both primary as well as secondary data
  • Comparative effectiveness & safety analyses using real-world data as external comparator for single arm clinical trials; strategic capabilities on how to design such studies to provide compelling and acceptable evidence for regulators.
  • Health technology assessment (HTA) expert including market access and Health economics; Strategic HTA capabilities from early-stage to post-authorisation phase.
  • Oncology - >100 projects/studies within solid tumours and hemato-oncology


Before NDA 

Chantal worked for IQVIA (2014-2022) where she held positions as global Director of Epidemiology and also within the IQVIA NEMEA Market Access & Health Economics and Outcomes Research business unit. She led global evidence generation, market access projects and real-world evidence studies for innovative medicine projects, within oncology in particular. 

Prior to joining IQVIA she worked as Market Access manager and medical advisor at GlaxoSmithKline, predominantly in Oncology & Rare Diseases. Overall, Chantal has worked in the domain of real-world research, epidemiology and health economics for over 15 years and has 3 years of clinical experience as a medical doctor.

Chantal holds a PhD in Health Economics and a MSc in Epidemiology, Erasmus University Rotterdam, as well as a MD degree from the University of Utrecht. Her research is published in various peer-reviewed journals and she has presented at national and international conferences.
