Building Expertise in Clinical Development
4Clinics was founded in 1997 with the goal of providing high-quality functional clinical development services to the life sciences sector. From its early years, the organisation focused on delivering reliable, methodologically sound support across key clinical development functions.
Over time, 4Clinics expanded its expertise beyond traditional clinical trials to include observational and epidemiological studies, with a particular emphasis on vaccines and immunology. This scientific focus positioned 4Clinics as a trusted partner for pharmaceutical and biotech companies, medical device manufacturers, research institutions, and non-governmental organisations.
Growth, Expertise, and Impact
Over more than two decades, 4Clinics developed into a specialised CRO with a strong international footprint and a reputation for scientific rigor and operational flexibility.
Key strengths included:
- Biostatistics and Data Management, including remote platforms for clinical data management, SAS programming, and statistical analysis
- Medical and Scientific Writing, supporting regulatory submissions, clinical study reports, and scientific publications
- Regulatory Affairs, guiding sponsors through complex regulatory environments
- Clinical Operations, supporting global clinical research programs
By combining deep technical expertise with adaptable delivery models, 4Clinics enabled efficient collaboration across international clinical research projects.
A Global Mindset, Enabled by Technology
A defining feature of 4Clinics’ evolution was its early adoption of remote and technology-enabled working models. By developing platforms that supported distributed teams, 4Clinics was able to provide clinical development services across borders while maintaining high quality and consistency.
With its headquarters in Belgium and additional presence in France and Morocco, 4Clinics supported global sponsors and research partners across multiple regions and therapeutic areas.
