CHDR values fruitful collaborations with partners throughout the Netherlands.

Medical centres in the Netherlands

CHDR is located in the heart of the Leiden Bio Science Park, situated in the middle of the ‘Randstad’ urban area (one of the largest conurbations in Europe), which encompasses the Netherlands’ four largest cities and is the most densely populated area in the Netherlands. CHDR’s central location and collaborations with top Dutch medical centres together provide a rich environment not only for knowledge exchange, but also for the recruitment of a range of patient populations.

Leiden University Medical Center

Our foundation originated from expertise within the Leiden University and the Leiden University Medical Center (LUMC), meaning that today CHDR enjoys a strong and long-standing partnership with the LUMC. This partnership facilitates direct access to an extensive knowledge base in Leiden, as well as access to different patient populations.

Erasmus University Medical Center

Erasmus MC in Rotterdam is the largest and most versatile of the eight university medical centres in the Netherlands. CHDR collaborates with Erasmus MC in the field of pulmonology (asthma, COPD, fibrosis), working together with Prof. Henk C. Hoogsteden, Professor of Pulmonary Diseases and Tuberculosis.

Amsterdam University Medical Centers 

Amsterdam UMC is one of the largest and most prominent hospitals in the Netherlands. CHDR collaborates with Amsterdam UMC in vascular medicine and inflammation (atherosclerosis, associated inflammation, lipids), working together with Prof. Erik Stroes, MD (Department of Vascular Medicine) and Prof. John J.P. Kastelein, MD (Professor of Medicine; Department of Vascular Medicine).

Clinical Network for Trials in Dermatology

The Clinical Network for Trials in Dermatology is a new network of dermatologists with a strong interest in science and education, in which more than 170 dermatologists from academic hospitals and peripheral clinics participate. Clinical trials at CHDR regularly involve this collaborative network. Partners include the Leiden University Medical Center (LUMC), Erasmus University Medical Center (Rotterdam), the Free University Medical Center (Amsterdam), teaching hospitals and skin and beauty therapists.

Clinical and Laboratory Chronic Hepatitis B Research Consortium 

Experts from the Amsterdam University Medical Centers (Amsterdam UMC), Leiden University Medical Center (LUMC) and CHDR have established a clinical and laboratory research consortium with the aim of ultimately finding a cure for Chronic Hepatitis B (CHB). Click here for more information.

The consortium is interested in collaborating with other parties, such as companies developing new drugs for CHB or CHD, or academic or other hospitals interested in HBV research.

Laboratory & analytical services

Good Biomarker Sciences 

Good Biomarker Sciences (GBS) specialises in functional bioassays applied to clinical studies, in the fields of haemostasis, immunity and cellular stress. GBS also performs biomarker validation across clinical, population and in vitro studies.

GBS is a successful spinout organisation from TNO (Netherlands Organisation for Applied Scientific Research), drawing on over 30 years of experience.

GBS conducts research laboratory services for the study of biomarkers, as well as providing advice on the selection of biomarkers for research protocols, the validation and devising of (new) tests and execution of assay series.

We also pursue our own research projects in order to expand our capabilities, with a particular emphasis on bringing to clinical trials the advanced techniques required to unravel complex biological responses in humans. Current research at GBS is focused on contact activation and new coagulation inhibitors, as well as immunity and inflammation-related targets.

The laboratory is housed in CHDR's Clinical Research Unit and works according to Good Clinical Laboratory Practice guidelines, maintaining high standards in documentation and customer focus.
