CHDR collaborates with multiple firms. CHDR is located in the heart of BioScience Park in Leiden which lays in the middle of the Randstad area (one of the largest conurbations in Europe). The conurbation consists of the four largest Dutch cities and the surrounding areas.

Medical Centres in the Netherlands

CHDR is located in the heart of BioScience Park in Leiden which lays in the middle of the Randstat area (one of the largest conurbations in Europe). The conurbation consists of the four largest Dutch cities and the surrounding areas, and is considered the most densely populated area in the Netherlands. CHDR’s unique location and collaborations with the top medical centers in the country provide a rich environment for exchange of knowledge and at the same time recruitment of different patient populations.

Leiden University Medical Center

CHDR originates from Leiden University (LU) and Leiden University Medical Center (LUMC) what results in a strong, long standing collaboration between CHDR and LUMC. This gives us direct access to extensive knowledge base in Leiden and at the same time access to different patient populations.

However, commonly used medications against psychiatric and neurological conditions such as depression and Alzheimer’s disease can also influence sleep. Therefore, studying sleeping subjects in a clinical trial can increase our knowledge regarding a compound’s neuropharmacology. After all, although sleep may appear to be a passive process, it requires the coordinated activity of many neurotransmitter systems in the CNS.

Erasmus University Medical Center

Erasmus MC in Rotterdam is the largest and most versatile of the eight university medical centers in the Netherlands.

Good Biomarker Sciences 

Good Biomarker Sciences (GBS) is specialized in fit-for-purpose functional bioassays applied to clinical studies, in the fields of haemostasis, immunity and cellular stress. We also perform biomarker validation across clinical, population and in vitro studies.

The laboratory is housed in CHDR clinical research unit. GBS is a successful spinout organisation from TNO (Netherlands Organisation for Applied Scientific Research) with over 30 years of experience.

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

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

GBS works with Good Clinical Laboratory Practice guidelines and maintains high quality standards in documentation and customer focus.
