Budapest, Hungary

Our Budapest clinic focuses on oncological, ADME, and mass balance studies, as well as rheumatology and renal impairment studies. As one of only 14 accredited Phase I units in Hungary, our centrally located clinic is easily accessible to patients and is within close proximity of additional hospital services if required. We’ve also developed excellent working relationships with university clinics and top institutions throughout the region to ensure we provide the safest, most effective solutions.


Groningen, the Netherlands

Our 150-bed clinical pharmacology unit in Groningen, the Netherlands is strategically located and directly connected to the Martini Hospital, including direct access to their intensive care unit. This partnership ensures we have access to the latest tools, technology, and expertise. We have extensive experience in positron emission tomography (PET), functional magnetic resonance imaging (fMRI) scans, cerebral spinal fluid (CSF) sampling, validated pain models, cognitive testing, spirometry, and ADME studies.


UCMG (Academic hospital Groningen)

In early 2022 ICON entered into a partnership with the University Medical Center Groningen (UMCG), one of the largest academic hospitals in The Netherlands that is renowned for performing cutting-edge scientific research. This unique collaboration resulted in the construction of a combined clinical research unit on the UMCG campus.

This unit holds 13 hospital-based beds, enabling the execution of innovative study designs and clinical trials that incorporate particularly invasive or specialized assessments in healthy subjects, like continuous CSF sampling and various medical imaging techniques like (f)MRI, SPECT, CT and PET. The unit also offers the opportunity to carry out early and late phase clinical research in special moderate to severe patients who have to stay in a hospital environment.

It has been designed in accordance with good clinical practice (GCP) to accommodate the delivery of complex clinical trials through all phases of research and is fully integrated with our clinic in Groningen, using ICON supported quality and IT systems.
