There are about 36633 clinical studies being (or have been) conducted in France. 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.
Behçet's disease (BD) is a systemic vasculitis that affects, especially, young people. Although its etiology remains unexplained, data suggest that the inflammatory response during BD results from a disruption of the homeostasis of innate and adaptive immune responses in genetically predisposed people. The microbiota could play a triggering role in BD, in particular the salivary and dental plaque microbiota. The aim of the Behçetbiot study is therefore to establish microbial profiles of dental plaque, pathological (on the mouth ulcer) and non-pathological mucous membrane, salivary and digestive and to compare them with control subjects not suffering from BD, related to the first degree, of the same socio-cultural level and to determine whether dysbiosis is correlated with a local and systemic pro-inflammatory response, by measuring salivary level of pro-inflammatory cytokines and blood level of CRP, fibrinogen, orosomucoïd and haptoglobin, and to compare them with controls.
Locoregional anesthesia techniques are now widely recommended in perioperative multimodal analgesia protocols. The transverse abdominal plane block (TAP block), which consists of the injection of a local anesthetic in the vascular-nervous plane between the internal oblique muscle and the transverse abdominal muscle, has seen a significant increase in abdominal surgery with the advent of ultrasound guidance. Aimed at blocking the nerves destined to the antero-lateral abdominal wall, it has shown a benefit in several abdominopelvic surgeries with in particular a reduction of pain and a morphine sparing during the 24 postoperative hours as well as a shortening of the delay of resumption of the intestinal transit. Ropivacaine is the molecule of choice in transverse abdominal plane block because of its better safety profile among long-acting local anesthetics. Nevertheless, transverse abdominal plane block using ropivacaine has a risk of systemic toxicity, correlated to the peak systemic resorption of the local anesthetic, whose low incidence is probably underestimated in patients under general anesthesia. In this context, the addition of diluted adrenaline to the ropivacaine solution is a common practice in loco-regional anesthesia, including transverse abdominal plane block, to increase the duration of the peripheral block and reduce the peak plasma concentration of the local anesthetic. The objective of our study is to compare the pharmacokinetics of total and free ropivacaine administered in transverse abdominal plane block at the minimum effective dosage of 1 mg/kg without and with the addition of epinephrine at the concentration of 1:200000 (5 µg/mL) in patients scheduled for laparoscopic colectomy. The hypothesis is a significant reduction in the mean maximum concentration (Cmax) of total or free plasma ropivacaine in the adrenalized block transverse abdominal plane group. The practical applications in case of verification of the hypothesis are the provision of an argument to recommend the systematic adrenalization of the transverse abdominal plane block with ropivacaine in the interest of patient safety and the prospect of a downward reassessment of the minimum time to be respected between the administration of a transverse abdominal plane block with ropivacaine and that of another locoregional anesthesia.
Due to different study designs, the sponsor separated Part C into this separate registration (NCT04958642), leaving Parts A/B in NCT02534844. The trial's final results for the primary outcome measure of Adverse Events (AE) will be reported here. This study is to evaluate how safe and effective adrabetadex is for participants with Niemann-Pick Type C1 (NPC1) disease who experience neurologic symptoms (listed under Keywords). In Parts A/B (NCT02534844), two out of every 3 participants will receive the study drug. The third participant will receive 1 to 2 small needle pricks at the location where the IT injection is normally made (sham control). In Part C, all participants will receive study drug.
The objective of this study is to assess safety and feasibility of Pressure-controlled intermittent Coronary Sinus Occlusion (PiCSO) therapy in patients with extensive ST elevation inferior wall myocardial infarction presenting with TIMI 0 or 1 and symptom duration ≤ 12 hours undergoing percutaneous coronary intervention (PCI) compared to standard PCI.
According to ESGO-ESTRO-ESMO guidelines, pelvic Sentinel lymph node detection is suitable for lymph node staging in endometrial carcinoma of the uteri. Nonetheless, a learning curve is mandatory to ensure the surgical quality of the sampling. The aim of the study is to assess the success of sentinel lymph node detection according to SHREC-Trial surgical strategy.
This study aims to evaluate the efficacy and safety of crovalimab in pediatric participants with aHUS.
The detection of developmental disorders in the child is often late because the parents do not have the information necessary to consult at the first clinical signs. For example, the diagnosis of autism spectrum disorders is made at the age of 5, so earlier diagnoses are possible earlier or even in the 1st year with appropriate questionnaires. An application (Malo) has been developed to allow through regular questionnaires from 1 month to 3 years old to assess the child's development by his parents in the form of a digital health record assessing several areas at regular intervals (monthly the 1st year then every 3 to 12 months): sensory, psychomotor development, sleep, height and weight, cognitive and addictions (especially to screens). The questions will be adapted to the age of the child. An alert suggesting to consult the general practitioner or the pediatrician will be generated according to an algorithm validated by a committee of experts. Based on a study model on health data already carried out as part of the triage application for patients suspected of COVID 19 coronavirus disease.fr with 14 million users in 6 months having improved the relevance of calls to the 15 (8 times fewer unnecessary calls) and general practitioners. This study will assess parental interest in this application.
Establish a cohort of pregnant women exposed to a COVID19 vaccine, whether or not they have experienced an adverse event, to assess the potential effects of vaccines on the course of pregnancy, on the fetus or newborn and on the mother.
This study will randomize patients recently discharged from the hospital with a confirmed diagnosis of type 1 acute myocardial infarction (Thygesen et al. 2018) and having additional cardiovascular risk factors.
Currents strategies for cancer diagnosis consist of the extraction of a solid tissue from the affected area. This sample enables the study of specific biomarkers and the genetic nature of the tumor. However, the tissue extraction is risky and painful for the patient and in some cases is unavailable in inaccessible tumors. In addition, cancer is a dynamic disease and during the course of disease, cancers generally become more heterogeneous. As a result of this heterogeneity, the bulk tumour might include a diverse collection of cells harbouring distinct molecular signatures with differential levels of sensitivity to treatment. This heterogeneity might result in a non-uniform distribution of genetically distinct tumour-cell subpopulations across and within disease sites (spatial heterogeneity) or temporal variations in the molecular makeup of cancer cells (temporal heterogeneity). To overcome these drawbacks, new alternatives are rising up, such as liquid biopsy. A liquid biopsy is the analysis of biomarkers in a non-solid biological tissue, mainly blood, which has remarkable advantages over the traditional method; it has no risk, it is non-invasive and painless, it does not require surgery and reduces cost and diagnosis time. Of the various circulating biomarkers, circulating tumor cells (CTCs) have particularly opened new windows. Circulating tumor cells (CTCs) are released into the bloodstream from primary cancer, metastasis, and even from a disseminated tumor cell reservoir. CTCs may ideally replace tissue biopsies in the prediction and monitoring of therapeutic responses and tumor recurrence. CTCs can be used to guide therapeutic cancer management and serve as drug targets. There are a wide range of instruments and methods for capturing, enriching, and enumerating CTCs. However, none of them is considered optimal. To improve the purity of CTCs, the study consortium has developed a cutting-edge microfluidic device (LUTON) to reduce leukocytes contamination while preserving CTCs viability. The added-value of the study innovation has been validated on clinical cell lines. The aim of this study is now to determine the performance of the device using patients' blood samples. For this purpose, CTCs from non-small cell lung metastatic cancer patients will be isolated using ClearCellFX1 before injection into the LUTON workflow. Collected cells will then be either growth in vitro or in ovo and the added value of this extra step of purification determined.
