There are about 13332 clinical studies being (or have been) conducted in Netherlands. The country of the clinical trial is determined by the location of where the clinical research is being studied. Most studies are often held in multiple locations & countries.
The study is perfomed with adult patients with non-small cell lung cancer treated with tyrosine kinase inhibitor. The objective is to collect repeated samples of blood from patients (starting) on a tyrosine kinase inhibitor, for liquid mutation testing, and pharmacokinetic analysis.
Colonoscopy is the gold standard for colorectal screening. The diagnostic accuracy of colonoscopy highly depends on the quality of inspection of the colon during the procedure. To increase detection new polyp detection systems based on artificial intelligence (AI) have been developed. However, these systems still depend on the ability of the endoscopist to adequately visualize the complete colonic mucosa, especially to detect smaller and more subtle lesions, or lesions hidden behind folds in the colon. With this study we want to combine a device to flatten the folds in the colon combined with an artificial intelligence system to further improve the detection rate of lesions during colonoscopy.
Rationale: Perirenal adipose tissue (PRAT) thickness has been associated to worsening renal function and hypertension. The role of PRAT in heart failure with a preserved ejection fraction (HFpEF) has never been established. The hypothesis of this study is that in patients with HFpEF the diameter of PRAT is increased compared with age, sex and BMI matched controls. Objective: The main objective is to determine whether PRAT thickness is increased in patients with HFpEF. Secondary objectives are to determine whether PRAT thickness is correlated to whole kidney perfusion, renal venous flow patterns, markers of glomerular and tubular damage and dysfunction, NT pro-BNP, renin and aldosterone. Lastly, this study aims to determine whether these correlations are similar for men and women with HFpEF. Study design: the proposed study is a single center, cross-sectional observational case-control study, including 30 HFpEF patients and 30 healthy controls. Study population: Adult patients with HFpEF with a body mass index (BMI) of <25.0 or >30.0 and healthy age, sex and BMI-matched controls. Intervention (if applicable): Not applicable. Main study parameters/endpoints: The primary endpoint will be the difference in diameter and volume of perirenal adipose tissue measured on dynamic contrast computed CT (DCE-CT) in patients with HFpEF vs. healthy age, sex and BMI matched controls. Nature and extent of the burden and risks associated with participation, benefit and group relatedness: Participating subjects will be asked to visit the University Medical Center Groningen (UMCG) twice (once for screening, once for testing visit). During the testing visit they will undergo intravenous contrast abdominal CT, renal sonography, blood drawing and urine collection. Risks associated with these procedure are very limited, rare and include bleeding and infection for venapunction, and contact dermatitis for ultrasound gel. Adverse events for CT include hypersensitivity reactions to contrast agent, which include skin rash, hypotension and bronchospasm.
In men without erectile problems, night time erections occur during the REM-sleep. For this study the current diagnostic test, the Rigiscan is compared, with the data from the TRIP-Patch during the night. To validate discriminating sensor-readings between flaccid state and full rigidity of the penis. Eventually, to have a validated device, a patch in the size of a postage stamp, that easily measures erectile function at home. Furthermore the temperature on the outside of the thigh will be measured.
This study is open to people with a type of cancer called dedifferentiated liposarcoma. People with advanced liposarcoma aged 18 or older who are not receiving any other cancer treatment can participate. The purpose of this study is to compare a medicine called brigimadlin (BI 907828) with doxorubicin in people with liposarcoma. Brigimadlin (BI 907828) is a so-called MDM2 inhibitor that is being developed to treat cancer. Doxorubicin is a medicine already used to treat cancer including liposarcoma. During the study, participants get either brigimadlin (BI 907828) or doxorubicin. Every 3 weeks, participants take brigimadlin (BI 907828) as tablets or doxorubicin as an infusion into a vein. Participants can switch to brigimadlin (BI 907828) treatment if they did not benefit from doxorubicin treatment. Participants can continue treatment in the study as long as they benefit from it and can tolerate it. Doctors regularly check the size of the tumour and check whether it has spread to other parts of the body. The doctors also regularly check participants' health and take note of any unwanted effects.
Objective: To explore the association between spatio-temporal blood flow velocities (peak systole and end-diastole at prior-stenosis, at maximum stenosis, and post-stenosis) and carotid plaque vulnerability defined by histology staining. Secondary, to assess the association between ultrasound elastography and carotid plaque vulnerability defined by histology staining. Furthermore, to assess the association between blood flow-derived parameters, including wall shear stress (WSS), vector complexity and vorticity, and plaque vulnerability. To evaluate the hemodynamic consequences of a CEA. Last, to explore whether the presence of circulating biomarkers is related to the degree of plaque vulnerability (as reflected by histology and/or ultrasound). Study design: A multicentre, prospective, observational, cohort study in a total of 70 patients. Study population: Patients with a carotid artery stenosis ≥50% according to clinically performed imaging (i.e. duplex, computed tomography angiography (CTA), or magnetic resonance angiography (MRA)) that are scheduled for a CEA. Intervention (observational): A carotid ultrasound with flow and elastography (strain and shear wave) measurements will be performed maximally 2 weeks prior to the CEA. In the first 20 included patients in the Radboudumc, a 10 mL blood sample will be collected during surgery via the arterial line that is applied for regular care. The plaque excised during CEA will be histologically examined to assess the plaque composition, and therefore plaque vulnerability. Ultrasound-based flow imaging will be repeated six weeks after the CEA to assess the hemodynamic consequences of the CEA procedure. Besides, clinical parameters will be subtracted from electronic health record or, if missing, anamnestically collected from the patient. Main study parameters/endpoints: Association between 2D spatio-temporal blood flow velocities (peak systole and end-diastole at prior-stenosis, maximum stenosis and post-stenosis), measured by ultrafast ultrasound measurements, and plaque vulnerability (stable versus unstable), defined by histology staining.
Different types of pain may be present in patients with hand osteoarthritis, including nociceptive pain and non-nociceptive pain. This makes adequate pain treatment difficult, and thus new treatment options are needed. To this end, this trial will evaluate the effect of transcutaneous pulsed radiofrequency for the treatment of hand osteoarthritis pain.
Depression is a recurrent debilitating psychiatric disorder with a lifetime prevalence of 20%. Even though antidepressants and psychotherapy are often effective, a substantial proportion of patients does not respond to currently used evidence-based treatments. The heterogeneous nature of depressive symptoms is a major obstacle for the development of novel effective treatments, and targeted treatments for depression are currently lacking. The investigators propose a targeted disease-modifying treatment for the clinically distinct form of depression related to childhood trauma (CT, emotional/ physical/sexual abuse or neglect before the age of18). CT-related depression is critically different from non-CT depression: it emerges earlier in life with more severe and recurrent symptoms and less favorable responses to treatment. With an average 25% prevalence in depression, there is a large and unmet need for therapeutic strategies to treat depression in individuals with substantial CT. The GR is the major cortisol receptor in the brain and rodent studies have shown that GR blockade at adult age can reverse the effects of early-life adversity. Therefore, GR blockade is a potential novel treatment for CT-related depression but this has never been investigated. Based on the underlying stress neurobiology, the aim is to investigate whether the biological sequelae of excessive stress due to CT can be targeted by blocking the glucocorticoid receptor (GR) using the generic drug mifepristone.
Sjogren's syndrome (SS) is a chronic, multisystem autoimmune disease characterized by lacrimal and salivary gland inflammation, with resultant dryness of the eyes and mouth and occasional glandular enlargement. In addition, a variety of systemic manifestations may occur; including fatigue, musculoskeletal symptoms, rashes, and internal organ (e.g., pulmonary, renal, hepatic, and neurologic) disease. Sjogren's syndrome may occur in isolation, primary Sjogren's syndrome (pSS), or in a secondary form, often associated with rheumatoid arthritis (RA), systemic lupus erythematosus (SLE), or systemic sclerosis. Ravagalimab is an investigational drug being developed to help treat patients with inflammatory diseases like SS. This study will evaluate how well ravagalimab works within the body and how safe it is in patients with primary SS (pSS). Ravagalimab, a potent CD40 antagonist is an investigational drug being developed for the treatment of Sjogren's syndrome (SS). This study is "double-blinded", which means that neither the trial participants nor the study doctors will know who will be given which study drug. Study doctors put the participants in 1 of 2 groups, called treatment arms. Each group receives a different treatment. There is a 1 in 2 chance that participants will be assigned to placebo. Participants 18-75 years of age with Sjogren's syndrome (SS) will be enrolled. Around 45 participants will be enrolled in the study in multiple sites within Netherlands. Participants will receive ravagalimab intravenous (IV) loading dose or IV placebo at baseline followed by subcutaneous (SC) ravagalimab or matching placebo for 22 weeks. There will be a higher treatment burden for participants in this trial compared to their standard of care. Participants will attend regular visits during the study at a hospital or clinic. The effect of the treatment will be checked by medical assessments, blood tests, labial gland (lip) biopsy, and checking for side effects and completing questionnaires.
The purpose of this study is to learn about the effects of three study medicines (encorafenib, cetuximab, and pembrolizumab) given together for the treatment of colorectal cancer that: - is metastatic (spread to other parts of the body); - has the condition of genetic hypermutability (tendency to mutation) or impaired DNA mismatch repair (MMR) - has a certain type of abnormal gene called "BRAF" and; - has not received prior treatment. All participants in this study will receive pembrolizumab at the study clinic as an intravenous (IV) infusion (given directly into a vein) at the study clinic. In addition, half of the participants will take encorafenib by mouth at home every day and cetuximab by IV infusion at the study clinic. The study team will monitor how each participant is doing with the study treatment during regular visits at the study clinic.
