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 objective of this observational laboratory study is to measure the correlation between 5-hydroxyindolacetic acid (5-HIAA) in platelet rich plasma and 5-HIAA in 24-hours urine collection in adult patients with a serotonin-producing neuro-endocrine tumor. Plasma and urine of included patients are collected and 5-HIAA values are measured with LCMS-MS and analysed.
In summary, breast conserving therapy (BCT) is an effective, save and widely used treatment technique for early breast cancer. Radiotherapy has shown to give better local control and survival benefit and is an integrated part of BCT. The simultaneous integrated boost (SIB) technique is a new treatment technique in breast irradiation. In this technique the whole breast is irradiated simultaneous with boosting the tumour bed, as part of BCT. Late radiation-induced toxicity has not been investigated in patients treated with radiotherapy using this technique. Proposed study will study the late radiation-induced toxicity, describe patients-rated complaints, quality of life, survival and local control curves in patients treated for early breast cancer with breast-conserving surgery in combination with radiotherapy with the SIB technique as compared to sequential radiotherapy treatment.
Patients receive study drug for one year (Part A). If, after the initial run-in phase, a sustained remission is reached they will be randomly split into one of three dose groups for another year (Part B). The maintenance of the sustained remission will be analyzed.
The aim of this study is to evaluate RBV plasma concentrations when used in combination with newly developed DAA combinations. If possible, its correlations with SVR rates and incidence of anaemia will be assessed in HCV-patients.
The purpose of this study is to determine if abatacept is effective in the treatment of early rheumatoid arthritis.
The purpose of study was to test whether rivaroxaban added to standard of care treatment, when compared to placebo, had the potential to reduce the incidence of the clinical events related to the clots and complications of the heart and brain (CV death, MI, or stroke) or the legs (acute limb ischemia or major amputation) in patients who had undergone recent procedure(s) to improve the blood flow of their legs.
Systemic sclerosis (SSc), or scleroderma is a connective tissue disease of autoimmune origin. It is a life-threatening orphan disease with severe physical and psychosocial consequences. IVA337 has a novel mechanism of action and this study is designed to compare IVA337 at two dose levels with a placebo control treatment. Patients will be unaware of the treatment they are receiving and will be randomized to one of three treatment arms , either IVA337 400mg bid, IVA337 600mg bid or placebo bid. They will receive drug for 48 weeks and during that time assessments will be made to monitor both the efficacy and safety of the treatment.
This study aims at investigating the direct effects of methylphenidate on school performance of primary school children. Although behavioral effects of this frequently prescribed drug are thoroughly studied (and confirmed), the effects of methylphenidate on school performance are less clear. Recent overviews indicate that effects are mainly quantitative and subject-specific. To gain more insight in this issue, the current double blind placebo controlled crossover study investigates not only the effects of methylphenidate on school performance but also it's effect on related variables such as short term memory, motivation and behavior. 60 children with ADHD are included and tested twice (with medication and with placebo) at their primary school.
Single-centre prospective randomized study will be included the patients who undergo elective cardiovascular surgery. Preoperative fluid deficit will be calculated by the formula as starvation period X 4 X weight. Patients will be divided into two groups: Group A (n=20); crystalloid as priming solution used in patients, Group B (n=20); colloids as priming solution used in patients. In addition to priming solutions, extracorporeal pump will be filled with 150 mL of Mannitol, 60 mL of NaHCO3 and 10000 IU Insulin. Standard anesthesia protocol will be administered to all patients. Ringer's Lactate will be given at first 30 minute after induction. Ringer's Lactate as fluid maintenance will be administered at a rate of 100 mL/h except in extracorporeal circulation. Goal-directed fluid management will be performed by PVI (Pleth Variability Index). Cut off level of PVI will be accepted %15.
The primary objective of the study is to determine the ability of reslizumab administered by subcutaneous injection to produce a corticosteroid-sparing effect in patients with oral corticosteroid (OCS)-dependent asthma and elevated blood eosinophils, without loss of asthma control.
