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.
The main objective of the study is to define population pharmacokinetic parameters and variability factors for paracetamol and its metabolites in overweight and obese children compared to children with normal weight for age and sex.
The aim of the study is to assess the number of patients with elevated blood tryptase for whom this elevation could be linked to a hereditary alpha-tryptase secretion abnormality or hyper-alpha-tryptasemia. This information will enable to better optimize the management and follow-up of patients who have experienced hypersensitivity reactions and have elevated basal blood tryptase levels. The patients will be offered the opportunity to take part in the study. If they consent to participate, they will be tested for hereditary hyper-alpha-tryptasemia. A blood sampling will be performed in the center. A few weeks after, the patient will be informed about the blood sample result during a medical consultation organized in the center.
Squamous cell cancers of the head and neck are classically correlated to excessive consumption of alcohol and tobacco and have a rather poor prognosis. However, the incidence of Head and Neck cancers in patients without alcohol-smoking risk factor has continued to increase in recent years, in relation to more and more frequent HPV contamination. Some studies show a difference in the expression of certain genes within the two groups of tumors (HPV+ and HPV-) including some that confer sensitivity to certain chemotherapies and others to radiotherapy. However, patients with HPV+ Head and Neck cancers are treated according to the same referential as HPV- Head and Neck cancers. There is therefore a real need for studies identifying predictive markers in order to be able to offer patients a more effective suitable and less invasive treatment.
Pregnancy is associated with significant changes in several aspects of haemostasis, especially an imbalance between procoagulant and anticoagulant factors. These changes contribute to creating a state of hypercoagulability, mainly at the end of pregnancy and during the post-partum period, protecting pregnant women from delivery haemorrhage, but exposing them to a major thromboembolic risk. Vascular diseases of pregnancy (VDP) are obstetric diseases which are linked to an ischaemic origin associated with placental thrombosis. These include pre-eclampsia, retroplacental haematoma, intrauterine growth retardation and even foetal death in utero. A number of risk factors have been identified for these VDPs, some of which have extremely serious consequences, the main one being antiphospholipid syndrome (APS). The diagnosis of VDP in a current or previous pregnancy requires close monitoring and joint management by an obstetrician, haemostasis physician, internist and medical biologist, particularly in terms of pre, peri- and post-partum anticoagulation in patients at increased risk of thromboembolism. The aim of treating APS during pregnancy is : to reduce the occurrence of maternal arterial or venous thrombotic complications in one hand and in the other hand to reduce the occurrence of obstetric complications, which are responsible of a significant morbimortality rate. The detection of a possible APS during pregnancy will therefore determine the specific management of patients. The latest guidelines from the Groupe Français d'Etude sur l'Hémostase et la Thrombose (GFHT) in 2022 recommended a diluted Russell's viper venom time (dRVVT) and an activated partial thromboplastin time (APTT) measured using a sensitive reagent such as silica (SCT) should be used to assess the presence of LA.
The number of CF adults is increasing year after year (61.7% in 2021) confirming that patients are living longer. These data do not leave aside the desire to see CF patients "age well" considering of all the comorbidities linked to aging. Among these comorbidities, the oral repercussions of cystic fibrosis and its treatments remain to this day little investigated. We know, however, that oral health, and periodontal health, is closely linked to general health. Indeed, the oral cavity presents one of the richest microbiota in the body, made up of bacteria, viruses, yeasts and archae organized into a biofilm at the interface of periodontal tissues. Periodontal diseases are partly linked to an imbalance in and loss of diversity within the commensal periodontal flora, aggravated by risk factors such as diabetes, which affects many CF adults. Early detection and treatment of periodontal diseases are therefore of primary interest in patients at increased risk of respiratory infections such as CF patients. This transversal research project aims to study the oral repercussions, notably periodontal disease prevalence in cystic fibrosis (CF) adult patients. Thus, this program will allow, on the one hand, the acquisition of clinical and biological data on periodontal and/or dental pathologies from which adult CF patients may suffer. These data will be accessible through an oral and periodontal clinical examination that will allow the identification of diagnostic clues. The quality of life related to oral health will also be investigated using a self-administered questionnaire. Clinical and biological data commonly recorded in the context of the medical follow-up of CF patients (ventilatory capacity, glycemic status, cytobacteriological examination of sputum, etc.) will also be taken into account in order to study any correlations with periodontal status. On the other hand, on a more fundamental level, this work aims to investigate the impact of CFTR protein dysfunction on the local immunity of the oral cavity and more particularly on the expression of antimicrobial peptides at the level of the periodontium. Thus this project is articulated around a strong axis which is "aging well" for adult CF patients thanks to the improvement of knowledge and ultimately the prevention of comorbidities linked to aging in CF adult patients and particularly those related to oral health.
Ketamine is an anaesthetic used in low doses to treat depressive disorders. A related molecule, Esketamine, has recently been launched on the market for the treatment of resistant depression. One of the side effects of ketamine, like Esketamine, is induction of transient dissociative state. Dissociation has been described as disruption in continuity of conscious thought and emotion, cognitive processes disorganisation and an alteration in self-perception and environment perception. A study of healthy volunteers receiving ketamine showed that this state was manifested by altered sensory perceptions, with increased noise sensitivity, visual distortions and altered time perception. Few studies have looked at this phenomenon in the Esketamine context. However, it is a frequent side effect. With ketamine, it has been shown that anxiety associated with dissociative experience reduces the antidepressant effect. Benzodiazepines use for anxiolytic purposes is also thought to limit the antidepressant effect. It is necessary to explore the Esketamine induced transient dissociative state in order to clarify this state and develop therapeutic strategies. The investigators have chosen a phenomenological approach, which is the only way to evaluate consciousness contents and structures, in order to explore this state using the experiential phenomenological interview.
The goal of this clinical trial is to compare as a first line of grade II skin acute GVHD sconventional treatment with steroids alone to a combination of steroids and extracoporeal photopheresis (ECP) The primary end point will compare Freedom from treatment failure at 6 months from randomization as defined by meeting all the following 4 conditions: - to be alive - without relapse of the hematological disease - without having required a new line of treatment for acute GVHD - without initiating a systemic treatment for chronic GVHD.
The goal of this proof of concept study is to determine if the visualization of the middle cerebral artery and its perforators, through 3D transtemporal ultrasound imaging, is possible thanks to an off-line analysis by 3D ultrasound localization microscopy. Visualization of these vessels would allow us to conclude on the presence, or absence, of an ischemic stroke in the region of the middle cerebral artery. To answer the question asked, 20 participants who suffered a stroke will carry out a transtemporal ultrasound examination specifically for research in the 7 days following his stroke. The data obtained will be analyzed by the CNRS medical imaging laboratory, in order to characterize the presence of a stroke and to compare the data obtained with that of standard examinations (CT and MRI).
Physical frailty and malnutrition are important factors in morbidity and mortality in patients with cirrhosis. No study has assessed the validity of Liver Frailty Index (LFI) against reference measures such as maximal lower limb strength. Main objective: To assess the association between LFI score and isometric maximal lower limb strength (quadriceps) in patients with cirrhosis.
The primary objectives of this study are to compare sacituzumab tirumotecan to Treatment of Physician's Choice (TPC) with respect to progression-free survival (PFS) per response evaluation criteria in solid tumors (RECIST 1.1), as assessed by blinded independent central review (BICR), and overall survival (OS). The primary hypotheses are that sacituzumab tirumotecan is superior to TPC with respect to PFS per RECIST 1.1, as assessed by BICR, and that sacituzumab tirumotecan is superior to TPC with respect to OS.
