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.
Rationale: Health related Quality of life (HRQoL) is impaired in patients with Turner and Klinefelter syndrome (TS and KS). It is unknown what the optimal endocrine treatment target values are that maximize HRQoL in patients with these syndromes. Therefore the relation between HRQoL and biochemical parameters will be studied in large cohorts of patients with TS and KS. This information will give essential insight that will help to improve endocrine treatment and HRQoL in these patients. Research objectives: To explore the relationship between biochemical parameters and HRQoL in patients with TS and KS. Hypothesis: Biochemical parameters are related to HRQoL in patients with TS and KS. Study design: Cross-sectional, observational, multicentre study Study population: Patients with KS or TS, 18 years or older Methods and procedures: To measure fatigue the Checklist Individual Strength (CIS-20) will be used, for QoL the 5-level EQ-5D (EQ-5D-L5) will be used and for stress the Perceived Stress Scale (PSS) and hair cortisol levels. For patients with KS the anxiety scale from the Liebowitz social anxiety scale (LSAS) will be used to measure social anxiety. To measure the long-term exposure to testosterone in KS patients, testosterone concentrations in hair will be measured. For patients with KS, all questions from the questionnaires will be discussed orally during a visit to the outpatients clinic. One extra tube of blood and a strand of hair will be collected during routine blood withdrawal. All other variables are already part of the standard patient care and are available in patient records. For patients with TS all information including the questionnaires and laboratory values is already available and will be collected from clinical records. Main study parameters/endpoints: The relationship between different hormonal parameters and HRQoL as measured by questionnaires. The main hormonal parameter that will be investigated in KS is testosterone in hair. For patients with Turner syndrome, free thyroxine (FT4), thyroid stimulating hormone (TSH) and liver enzymes, which have already been collected, will be investigated. The relationships between the EQ-5D-L5 score and testosterone in hair (in patients with KS) and thyroid hormone status (in patients with TS) are the primary outcomes.
To explore the feasibility of sentinel lymph node identification by SPIO injection followed by MRI in head-and-neck cancer patients.
Fractional flow reserve (FFR) is the current gold standard for correct decision making with respect to revascularization in the catheterization laboratory. FFR is measured by using a pressure guidewire equipped with a pressure sensor, positioned distal to the stenosis under investigation. A newly developed pressure wire using open wire technology has recently become commercially available. The purpose of this study is to evaluate whether the Wirecath pressure guidewire can be used as standard pressure guidewire. The effectiveness of the device will be investigated by comparing Wirecath FFR measurements with the measurements of another regular sensor-tipped pressure guidewires during simultaneous FFR measurements in the same vessel.
Primary Objective: To assess the long-term safety and tolerability in patients with cold agglutinin disease (CAD), after multiple doses of SAR445088 Secondary Objective: To assess, in patients with cold agglutinin disease (CAD), after multiple doses of SAR445088: - The long-term effect of SAR445088 on complement mediated hemolysis - The long-term pharmacodynamics (PD) effect of SAR445088 relating to complement inhibition - The long-term pharmacokinetic (PK) profile of SAR445088 - The long-term immunogenicity of SAR445088
This study will be a prospective, multi-centred, non-randomized study to investigate the safety and performance of the PerQseal® + in up to 90 patients in up to 8 European investigational sites. The PerQseal® + shall be indicated for the percutaneous closure of femoral artery punctures and to induce arterial haemostasis in patients undergoing endovascular procedures requiring an arteriotomy created with 14 - 22F sheaths (arteriotomy up to 26 F).
TransCon TLR7/8 Agonist is an investigational drug being developed for treatment of locally advanced or metastatic solid tumors. This Phase 1/2 study will evaluate TransCon TLR7/8 Agonist as monotherapy or in combination with pembrolizumab in dose escalation and dose expansion. Participants will receive intratumoral (IT) injection of TransCon TLR7/8 Agonist every cycle. The primary objectives are to evaluate safety and tolerability, and define the Maximum Tolerated Dose (MTD) and Recommended Phase 2 Dose (RP2D) of TransCon TLR7/8 Agonist alone or in combination with pembrolizumab.
The MODULAR ATP Clinical Study is designed to demonstrate safety, performance, and effectiveness of the Modular Cardiac Rhythm Management (mCRM) Therapy System.
Rationale: Irritable Bowel Syndrome (IBS) is a disease that affects a large number of people. To date, no adequate treatment is available. This is partially due to the heterogeneity of the patients and the complicated pathology in which not all mechanisms are understood. Based on results of in vitro screening within the IBSQUtrition project, we selected promising dietary supplements for validation of their potential beneficial effects on stool pattern in IBS-Constipation (IBS-C) patients. Objective: The primary objective is to determine the effects of a 4-week intervention with either a prebiotic supplement or a probiotic supplement on stool pattern (including stool frequency, consistency, and volume) in IBS-C patients. The secondary objective is to determine the effects if this intervention on GI complaints and quality of life in IBS-C patients. Study design: A double-blind, randomized, placebo-controlled trial will be conducted with three parallel intervention arms Study population: 180 adult (18-70 yrs) IBS patients with a constipation-predominant subtype Intervention: A 4 week run-in period will be followed by a 4-week intervention period with three parallel arms: 1) prebiotic supplement, 2) probiotic supplement, and 3) Placebo supplement, during which the study participants consume the respective supplement twice per day. Main study parameters/endpoints: The primary study parameter is stool pattern: stool frequency, stool consistency; and stool volume. The secondary study parameters are gastrointestinal complaints, Quality of Life, and HADS. Nature and extent of the burden and risks associated with participation, benefit and group relatedness: Study participants have to invest about 14.5 hours of their time in this study mainly to complete several questionnaires (short daily questionnaire, longer questionnaires at three occasions), which is conveniently all possible from home. They have to comply to consume a supplement twice daily for four weeks. At two time points they have to collect their stool for five consecutive days. There are limited risks for the study participants.
The objective of this study is to evaluate real world long-term functional outcomes, safety and performance of the Indigo Aspiration System for the treatment of pulmonary embolism (PE).
A study to examine the safety, tolerability, and pharmacokinetics of single- and multiple-ascending doses of ACT-777991 in healthy subjects.
