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.
SUMMARY Rationale: Pancreatic ductal adenocarcinoma (PDAC) is one of the most lethal cancers, its incidence increases with age. Many patients with localized (non-metastatic) PC have significant comorbidities, advanced age or a poor performance status which preclude chemotherapy and surgery. Because these patients are currently left untreated, it is desirable to find tolerable treatment options for these patients. A short course of high-dose precise radiation therapy i.e. stereotactic ablative body radiotherapy (SABR) may be feasible in these patients. Review of existing SABR literature for PDAC shows high local control rates, with relatively low toxicity and it was demonstrated to be feasible and well tolerated even in elderly patients. It is unknown whether SABR improves outcomes in this group. The main goal of the current study is to investigate if SABR may relieve tumor-related symptoms, postpone a decrease in global QoL and potentially prolong survival in this patient group compared to the current treatment of choice, best supportive care. Objective: To investigate the potential benefit in survival and quality of life after SABR in patients with localised PDAC for whom no other treatment is available, as compared to controls managed with best supportive care. Study design: A multicentre randomized controlled trial Study population: Patients with biopsy proven, localized PDAC, unfit for chemotherapy and surgery or those who refuse these treatments. They will be randomized between SABR versus best supportive care. Intervention: consists of SABR to the primary tumour in 5 fractions of 8 Gy. Main study endpoints: Primary endpoint is the overall survival rate at six months (from randomization). Secondary endpoints include the evaluation of time to decreased global quality of life (QoL, using the QLQ- C30 and EORTC-PAN26), NRS pain response and Ca19.9 response, acute and subacute toxicity using CTCAEv5.0 and progression-free survival in the treated patients using imaging. It is hypothesized that in frail patients with PDAC, SABR may relieve tumor-related symptoms, improve the quality of life and prolong survival compared to best supportive care. Its aim is to investigate the outcomes of SABR with respect to overall survival, pain response, toxicity and quality of life in patients with non-metastasized PDAC for whom standard radical treatment in the form of surgery or chemotherapy is either too toxic, not possible due to comorbidities, or is refused.
Background: Nowadays, tissue preserving, aesthetically high-quality and sustainable dentistry is more and more becoming the standard way of treatment. To reach those standards, one of the treatment options is applying a partial indirect restoration made by glass ceramics using immediate dental sealing (IDS). Using IDS, a protocol is followed to applicate a dentin bonding agent to freshly cut dentin when it is exposed during tooth preparation for indirect restorations (inlays/onlays, crowns). The preparation made for partial restorations is minimal invasive. Glass ceramic restorations have very high survival rates (90 to 100% after five years) (Morimoto et al., 2016) and glass ceramic mimics the color and structure of the tooth very well. This kind of treatment is gaining interest and increasingly applied however little information is available on the long-term effects when multiple general practitioners apply these restorations. Objectives: The main goal of this study is to evaluate partial posterior ceramic restorations with the application of an immediate dentin sealing (IDS) performed by various practitioners. Study design and population: Twenty dental practitioners, who followed a course on making ceramic partial restorations using IDS, will be asked to include patients for this study. The dental practitioners are being asked to share their data (occlusal light photo's, impression and x-rays) of twenty-five restorations they make after having the course. Restorations of individuals with a minimum age of 18 will be included. The information from pictures and impressions will be evaluated. Items to evaluate The practitioners will be interviewed to get to know in what circumstances they do their treatment. Items that are discussed are: - using rubber dam; - using magnification by means of loupes/microscope; - scheduled time for the treatment; - number of restorations after following the course. Initial data (gathered directly after treatment) will be evaluated looking at: - surface of preparation after IDS; - size of the prepared surface; - color. Follow up data will be evaluated looking at: - tooth extraction - fracture restoration - fracture tooth - secondairy caries - de-bonding - endodontic problems Outcome: Failures (fracture, de-bonding, secondairy cariës, endodontic problems) are the main outcome measurements. Description and estimation of the load and risk for the subjects: No extra intervention is performed. The dental practitioners will provide their data (i.e. impressions, occlusal light photo's) and these will be evaluated by the researchers. Follow up data will be gathered from X-rays already made for periodical oral examination (taking the caries risk into account). Summarizing, there is no extra load or risk for the patients. Studie design Prospective practice-based research, multicenter.

Cabozantinib is a drug which is used to treat metastasized kidney cancer. While it works well, it has a lot of side effects and is quite expensive (€213,- every tablet, €6403,- every month). The standard recommended dose is 60 mg once a day, taken in fasted state. This means patients are not allowed to eat at least 2 hours before and one hour after taking cabozantinib. In daily practice, this is difficult for patients. It might be that by taking with breakfast the chance of side effects like nausea and diarrhea decreases. If patients take cabozantinib with breakfast, the body will have a higher uptake of the drug. Often the dose of cabozantinib has to be lowered due to side effects. All tablets cabozantinib have the same price, despite how many milligrams are in the tablets. Cabozantinib stays in the body for a long time after ingestion. It takes approximately 120 hours before half of the medicine has left the body. This means it might not be necessary to take cabozantinib every day. Therefore, it is interesting to investigate if taking cabozantinib with breakfast makes it possible to skip taking cabozantinib once in a while. In this study, the investigators want to investigate to what extent the exposure of cabozantinib increases after ingestion with a light breakfast. The results from this study will be used for the development of alternative dosing regimens with cabozantinib tablets of 60 mg taken with a light breakfast including skipping days. In this study, patients will randomized to start with taking cabozantinib in fasted state (standard regimen) and taking cabozantinib with a light breakfast (experimental regimen). Menu options will be provided. After at least 4 weeks taking cabozantinib according to the randomized regimen, patients will be submitted to the hospital for one day to measure the amount of cabozantinib in the blood at several points of time. This will be measured by venepuncture and fingerprick microsampling. When all blood samples have been collected, the patient will switch to the other regimen. After at least 4 weeks taking cabozantinib according to the second regimen, venous blood samples will be collected in exactly the same way. After all patients have completed the study, an analysis will be performed to determine the change in exposure to cabozantinib when it is taken with a light breakfast. The results will be used in order to determine the definitive experimental dosing regimens that will be investigated a subsequent study. Patients will be monitored for side effects, especially nausea and/or diarrhea. The primary goal is to investigate to what extent the exposure of cabozantinib increases by taking cabozantinib with a light breakfast compared to taking cabozantinib in fasted state. The secondary objective is to investigate the analytical feasibility of microsampling (finger prick) for cabozantinib concentration measurements and to monitor side effects.
This study will investigate the potential benefit of scheduled natural daylight exposure to improve glucose control in type 2 diabetes (T2D) patients and to unravel molecular mechanisms underlying the effects of natural daylight on circadian clocks and (glucose) metabolism in human skeletal muscle from T2D patients. Participants will stay at our research facilities and will be exposed to natural daylight or artificial light during the daytime over 4.5 days in a randomized cross-over design. For both conditions, the evening and night will be spent under standardized dim and dark conditions.
