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 Nellix Endovascular Sealing Prosthesis (EVAS) endoprosthesis is a new device aimed at prophylactic treatment of abdominal aortic aneurysms. In regular follow up conventional CT-imaging is used for surveillance. In this study dynamic CT imaging in patients pre- and post-operative will be assessed for device changes and anatomical variances.
This is a prospective single- center observational study in the Leiden University Medical Center in approximately 250 children (<12 years) undergoing elective cardiac surgery, for congenital heart disease. The parents/guardians of the children will be asked to fill out a questionnaire, to asses respiratory symptoms in the last weeks, before the operation of their child. In the operating theatre, a nasopharyngeal swab will collected. Clinical data will be collected daily during paediatric intensive care admission, and date of discharge from paediatric intensive care unit and from hospital are recorded. If children are still intubated at day 4 a second nasopharyngeal swab and residual blood will be collected. The samples will be tested for rhinovirus with a polymerase chain reaction. Main study parameter is the paediatric intensive care unit length of stay in per-operative rhinovirus -positive compared to rhinovirus-negative patients.
To determine whether treatment with alpelisib plus fulvestrant prolongs progression-free survival compared to fulvestrant and placebo in men and postmenopausal women with hormone receptor positive (HR+), HER2-negative advanced breast cancer, who received prior treatment with an Aromatase Inhibitor either as (neo)adjuvant or for advanced disease.
This is a two-arm Phase 1b feasibility trial consisting of 20 patients receiving the combination of ipilimumab+nivolumab, either adjuvant, or split neo-adjuvant and adjuvant.
Both Neurofibromatosis type 1 (NF1) and Tuberous Sclerosis Complex (TSC) are highly heterogeneous diseases. Cognitive features seem to vary widely even between family members carrying the same mutation. This phenotypic variability is not well understood, but is generally assumed to be caused by modifier genes which regulate the affected pathways. However, recent studies brought forward an alternative explanation for the phenotypic variability. Post-mortem studies showed that second hit mutations causing loss of the second ('healthy') allele are more widespread than previously believed. These loss of heterozygosity (LOH) mutations cause bi-allelic loss of the disease-linked gene and are known to cause the gross of somatic features in both diseases (like neurofibromas and hamartomas). Hence, it could be the stochastic occurrence of second-hit mutations in the brain are the cause of the variable cognitive phenotypes. To investigate to what extent these LOH mutations in the brain contribute to the phenotype and to what extent this variation is due to genetic modifiers factors is unknown. The investigators therefore propose to elucidate this variability by comparing the correlation of cognitive features of monozygotic twins with NF1 or TSC to healthy twins in the population. If modifier genes are the cause of the variability of cognitive features in NF1 and TSC the investigators expect that the variability in cognitive tests in monozygotic twins is the same as monozygotic twins in the healthy population. However, if the variability is caused by the occurrence of LOH mutations, the investigators expect to have a lower correlation in our monozygotic patients compared to the healthy twins.
This is a multicenter, randomized, 1:1, non-comparative phase II trial. Patients with early stage MPM will be randomized between Arm A: immediate P/D followed by three cycles of chemotherapy (pemetrexed 500mg/m2 and cisplatin 75 mg/m2, both drugs given on day 1, every three weeks) Arm B: three cycles of chemotherapy (same regimen) followed by P/D, for non-progressing patients
The objective of the current study is to assess the effect of 6-day dietary nitrate ingestion on high intensity intermittent sports performance in recreational soccer players.
The purpose of this study is to determine whether RPC1063 is effective in the treatment of Ulcerative Colitis (UC).
The primary and general objective of the clinical introduction of the SFP as the current standard of care is to improve the quality of radiotherapy for head and neck cancer patients by reducing radiation-induced side effects without hampering treatment efficacy in terms of locoregional tumour control and overall survival and to systematically evaluate the beneficial effect of newly introduced radiation technology for this particular group of patients. The clinical introduction of the SFP will allow for a systematic and broad scale quality improvement cycle for head and neck cancer patients treated with radiotherapy. In fact, this methodology can be considered a kind of quality circle for the clinical introduction of new radiation techniques, aiming at continuous efforts for further improvement.
This study was designed to explore CDZ173, a selective PI3Kδ inhibitor, in patients with genetically activated PI3Kδ, i.e., patients with Activated phosphoinositide 3-kinase delta syndrome/ p110δ-activating mutation causing senescent T cells, lymphadenopathy and immunodeficiency (APDS/PASLI). The study consisted of two parts: Part I was the open label part designed to establish the safety and pharmacokinetics of CDZ173 in the target population, as well as to select the optimal dose to be tested in Part II. Part II was designed to assess efficacy and safety of CDZ173 in the target population.
