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 purpose of this study is to compare the effectiveness of daratumumab when combined with lenalidomide and dexamethasone (DRd) to that of lenalidomide and dexamethasone (Rd), in terms of progression-free survival in participants with relapsed or refractory multiple myeloma.
The Bone-Anchored Hearing Aid (Baha) system consists of an implanted part and sound processor. The system provides a hearing solution for a subgroup of patients who cannot sufficiently profit from conventional hearing aids. Disadvantageous are its high rate (up to 40%) of associated peri-implant dermatitis. This research project is part of an attempt to reduce the amount of peri-implant dermatitis. Besides an attempt of Holgers to identify the skin flora in relation to infection around the abutment using a standard culture which yielded limited and no clinically relevant results, little is known about the microbiome on the abutment or its interaction with the commensal skin flora. Moreover, conventional cultures are not very sensitive in identifying bacteria. In 2010, Budding et al. introduced IS-pro. Is-pro is a novel 16S-23S rDNA interspace (IS)- region-based profiling method. This technology was devised to enable high-throughput molecular fingerprinting of microbioma. Since IS-pro is quick and relatively inexpensive, these environments can also be monitored over time by repeating the test. This paves the way for researching the microbiome on the abutment and it could enable clinically objective follow up of treatments in vivo using the human as a host. This technique allows researchers to even discover unknown, previously unidentified bacteria. Additionally, Scanning Electron Microscopy will be used to assess the spatial distribution and composition of bacteria on the abutment. The first step, using these techniques, is to determine the bacteria which inhabit the abutment also in relation to the surrounding skin. Additionally, the relationship with skin-implant infections and the effect of treatments will be monitored. Depending on these primary scientific results, a subsequent study will be devised to study (experimental) treatments in a randomized, controlled fashion. Objectives of the study: 1. To identify the bacterial flora on the abutment in a phylum/species classification. 2. To assess the relationships between the commensal skin flora and the flora on the abutment and to study if clinical signs of peri-implant skin infection and subsequent treatment are associated with a change in bacterial composition. 3. To assess if there exists a relationship between skin hygiene and the transient skin flora.
It has been suggested that obese people are more sensitive to sensory and rewarding effects of food, aspects that mediate food preferences and intake. Individuals that underwent Roux-en-Y gastric bypass surgery frequently report changes in food preference. They indicate a decreased preference for highly rewarding energy dense foods. Changes in food preference might be related to alterations in central (brain) mechanisms, related to reward sensing. The smell and sight of food can be considered as anticipatory cues for the rewarding effects of food intake. The aim of this study is to determine the effect of gastric bypass surgery on (alterations in) food preferences. Secondly, this study aims at assessing the effect of gastric bypass surgery on the brain reward response when exposed to sight and smell of food stimuli with different sugar and fat contents.
The purpose of this study is to generate detailed insight into which therapies of giant intracranial aneurysms are being conducted, to document the natural history and the outcome of treatment over 5 years after inclusion into the Registry and to follow imaging data of giant aneurysms over years after diagnosis.
The study PNET 5 MB has been designed for children with medulloblastoma of standard risk (according to the risk-group definitions which have been used so far; e.g. in PNET 4). With the advent of biological parameters for stratification into clinical medulloblastoma trials, the ß-catenin status will be the only criterion according to which study patients will be assigned to either treatment arm PNET 5 MB - LR or to PNET 5 MB - SR, respectively. The initial diagnostic assessments (imaging, staging, histology, and tumor biology) required for study entry are the same for both treatment arms. With the amendment for version 12 of the protocol, patients who have a WNT-activated medulloblastoma with clinically high-risk features can be included in the PNET 5 MB WNT-HR study, and patients with a high-risk SHH medulloblastoma with TP53 mutation (both somatic or germline including mosaicism) can be included in the PNET5 MB SHH-TP53 study. Data on patients with pathogenic germline alteration or cancer predisposition syndrome, who cannot be included in any prospective trial due to unavailability or due to physician or family decision, can be documented within the observational PNET 5 MB registry.
This study will test the hypothesis that MSCs in combination with Everolimus facilitate Tacrolimus withdrawal, reduce fibrosis and decrease the incidence of opportunistic infections compared to standard tacrolimus dose.
The investigators will perform a randomized phase II study to investigate if the addition of cetuximab to MTX is beneficial for the patient. Because no data on this combination are available the investigators will start with a phase Ib study to investigate the feasibility of the schedule.
Narrowing of coronary arteries interferes with blood flow and can cause chest pain. But patients may have more than one narrowing and studies have shown that not all narrowings need to be treated. To identify the narrowings that need treating cardiologists sometimes quantify the extent of the narrowing by measuring fractional flow reserve (FFR, the ratio of the pressure in the aorta to the pressure downstream of the narrowing).This technique requires the administration of drugs that add cost and time to the procedure and in some countries are simply unavailable. As a result despite the clear health and healthcare costs benefits of FFR its use is limited to less than 5% of procedure. We have developed a new technique called the instantaneous wave-free ratio (iFR) that does not require the administration of drugs for its accurate assessment. It has been approved for use in this indication. This study aims to compare clinical outcomes of patients whose treatment has been guided by iFR to those whose treatment has been guided by FFR. If iFR is found to provide the same clinical outcomes as FFR its adoption will permit the clear benefits of this approach of identifying the coronary narrowings that really need treatment to be applicable to a much larger patient population and further improve healthcare costs.
Despite the fact that the majority of the patients with limited disease SCLC will respond very well to the standard treatment, a great proportion will relapse within 12 - 24 months. Several studies in patients with lung cancer suggested a possible favourable association between the increased presence of immunologically active cells in the tumour and survival. Nivolumab and ipilimumab are proteins, which help your immune system to attack and destroy cancer cells by your immune cells. Early clinical trials with nivolumab and ipilimumab have shown activity in a broad range of cancers, including SCLC. The aim of the current study is to investigate the efficacy (how well the treatment works) and tolerability (how severe the side effects are) of the standard treatment (chemotherapy and radiotherapy) alone, compared with the standard treatment followed by nivolumab and ipilimumab in patients with limited SCLC.
The primary purpose of this study is to evaluate the clinical and radiographic performance of the G7 Acetabular Cup System.
