The research of the Department of Endocrinology is part of the Kidney Center and the Cardiovascular Center of the Research Institute GUIDE (Groningen University Institute for Drug Exploration). The mission of GUIDE is to promote and execute innovative drug development research which is based on a thorough and detailed understanding of the pathophysiology of diseases, and the development of new (ways of administration of) drugs. New techniques like genomics, proteomics and bioinformatics play a major role in this development.

Participation in (inter)national clinical trials



The Durability of Twice-Daily Insulin Lispro Low Mixture Compared to Once-Daily  Insulin Glargine when added to Existing Oral Therapy in Patients with Type 2 Diabetes  and Inadequate Glycemic Control ( Identifier: NCT00279201)



A Randomized Trial Comparing Two Therapies: Basal Insulin/Glargine, Exenatide and Metformin Therapy (BET) of Basal Insulin/Glargin, Bolus Insulin Lispro and Metformin Therapy (BBT) in Subjects with Type 2 Diabetes who were Previously Treated by Basal Insulin Glargine with either Metformin or Metformin and Sulfonylurea

( Identifier:  NCT00960661)



Study to assess the effects of high protein diet in obesity, the LOWER Study

( Identifier:  NCT00862953)



The influence of the needle length on long term glycaemic control in insulin using obese diabetic subjects.

( Identifier:  NCT00541372)



Diagnostic value of 11C-metomidate Positron Emission Tomography/Computerized Tomography (PET/CT) for the evaluation of primary aldosteronism – a pilot study (NL28866)



Aldosterone-Renine Ratio to diagnose primary Aldosteronism and a Tool to select proper antihypertensive treatment -  The Dutch ARRAT Study (NL11725)


SPARTACUS - Subtyping Primary Aldosteronism: a Randomized Trial comparing Adrenal vein sampling and CompUted tomography Scan



Towards cost-effective diagnostic management of patients with primary aldosteronism: adrenal vein sampling or CT-scan (NL30849)



A Double-Blind, Randomized Phase III Study Evaluating the Efficacy and Safety of Sorafenib Compared to Placebo in Locally Advanced/Metastatic RAI-Refractory differentiated thyroid cancer ( Identifier: NCT00984282)



An international, randomized, double-blinded, phase 3 efficacy study of XL184 versus placebo in subjects with unresectable, locally advanced, or metastatic medullary thyroid cancer.

( Identifier: NCT 00704730)



A Study of RO5185426 (Vemurafenib) in Patients With Metastatic or Unresectable Papillary Thyroid Cancer Positive for the BRAF V600 Mutation.

( Identifier: NCT01286753)



A phase II study to investigate the efficacy of RAD001 (Afinitor®, everolimus) in patients

with irresectable recurrent or metastatic differentiated, undifferentiated (anaplastic) and

medullary thyroid carcinoma (patients progressive on Sorafenib or XL-184, or with

intolerance to Sorafenib or XL-184)

( Identifier: NCT01118065)



Visualizing vascular endothelial growth factor (VEGF) producing lesions in Von Hippel-Lindau disease

( Identifier: NCT00970970)



National project for screening of pancreatic neuroendocrine tumours in Multiple Endocrine Neoplasia type 1 (MEN1) and Von Hippel-Lindau (VHL) disease (NTR 1668)  



Phenoxybenzamine Versus Doxazosin in PCC Patients.

A study comparing effects of preoperative treatment with either phenoxybenzamine or doxazosin on intraoperative hemodynamic control in patients undergoing surgical resection of a phaeochromocytoma.

( Identifier: NCT01379898)


DIAPRIM in a rat-model:

A study to investigate the adaptation of the immune response during pregnancy in BBDP (a model for type 1 diabetes) rats versus healthy controls. This study showed an adverse pregnancy outcome in diabetic rats as compared to healthy controls. Since a different baseline peripheral immune response and different immunological adaptations to pregnancy were found in diabetic animals vs. healthy controls as well, it is imaginable that this aberrant immune response in diabetic rats is involved in the development of the demonstrated adverse pregnancy outcome.


DIAPRIM in a human-model:

A study to investigate the adaptation of the immune response during pregnancy in women with pregestational type 1 and 2 diabetes versus healthy controls (NTR2195). At the moment, almost all patients are included in the study, samples are obtained and analysis of the data is in progress.



A study to investigate the effects of Advanced Glycation Endproducts (AGEs) on pregnancies complicated by diabetes mellitus (NTR2356). Inclusions and data collection is ongoing.



A randomized double blind cross-over study of the effects of low dose and high dose hydrocortisone replacement therapy on cognition, quality of life, metabolic profile and somatosensation in

patients with secondary adrenal insufficiency. ( Identifier NCT01546922)
