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 aim of this study is to provide darolutamide treatment to patients who participated in a previous study with darolutamide supported by Bayer and the treating doctor considers that the continuation of the treatment with darolutamide to be beneficial. Patients will be carried over from the previous studies and continue in this study with darolutamide treatment on the same dosage. They will also return to the study centers for doctor's visits as often as they did in the previous study.
Epidemiological data have related particulate matter (PM), nitrogen dioxide (NO2) and ozone (O3) to COVID-19 morbidity and mortality at the population level. Air pollution may be related to an increase in the COVID-19 severity and lethality through its impact on chronic diseases such as cardiovascular and respiratory diseases and diabetes that are also the main comorbidities associated with COVID-19. Epidemiological studies using individual data are needed to provide more precise estimate of the association between air pollution exposure and COVID-19. In this multicenter prospective study, the investigators will analyze the number of deaths in COVID-19 confirmed cases in geriatric patients according to long-term exposure to air pollution, taking into account confounders such as diabetes, hypertension, age, and BMI. Exposure to air pollution will be estimated as the mean concentration of air pollutants at the residential address during the previous two years. In addition, the investigators will explore the relationship between short-term variations in air pollutants, relative humidity, temperature, UV radiations, pollen and the occurrence of COVID-19.
This is a multicenter, open-label, nonrandomized, Phase 2 umbrella study of retifanlimab in participants who have advanced or metastatic endometrial cancer that has progressed on or after platinum-based chemotherapy. retifanlimab will be administered as monotherapy or in combination with other immunotherapy or targeted agents.

Impacts of the Covid-19 epidemic and associated lockdown measures on the management, health and behaviors of cystic fibrosis patients during the 2020 epidemic
Severe asthma is a condition characterized by a lower sensitivity to high doses of inhaled corticosteroids combined with a second controller, most often a long-acting bronchodilator. It concerns approximately 5% of asthmatics. Treatment failure and co-morbidities induced by systemic corticosteroid therapy can cause debilitating dyspnea, limited physical activity, and impaired quality of life. Severe asthma could therefore be associated with major presenteeism, defined as the presence of an employee at work despite his health issues and which implies a limitation of the employee's productive capacity. Uncontrolled asthma and co-morbidities of asthma have been shown to be associated with a decrease in work productivity that includes absenteeism and presenteeism. Although there is little data, a recent study found a decline in work productivity in severe asthma. Various factors associated with presenteeism could be involved, such as asthma control, frequency and severity of exacerbations, comorbidities, or treatments. Biotherapies targeting the signaling pathways involved in airway inflammation improve asthma control, decrease the frequency of asthma exacerbations which are major determinants of quality of life, improve lung function, and allow oral steroid sparing. Biotherapies could therefore be associated with a decrease in presenteeism. The objective of the study is to describe the evolution of presenteeism at work, evaluated by the WPAI: Asthma, after 6 months of treatment by biotherapy and to identify factors associated with this evolution
The French Public Health strategy 2018-2022 aims to reduce inappropriate prescriptions, as potentially dangerous for individuals and collectively. The reduction of co-prescriptions at Risk of Drug Interactions (RoDI) could decrease the prevalence of iatrogenic diseases, and increase the persistence of treatments with a growing efficacy of treatments, in particular in elderly populations. A recent study conducted by our team showed that, in out-patient setting, 2.7% of co-prescriptions contains medications at RoDI of high degree of severity (object of a contra-indication or non-recommended). Up today, there is no French experience concerning the identification of RoDI among the prescriptions performed at the end of a hospitalisation. In France, the recent development of hospital data warehouses is a huge opportunity to develop a system that can identify efficiently co-prescriptions at RoDI and provide feedback directly to prescribers in order to reduce their frequency in hospital context. The primary objective of this study is to evaluate the capacity of a system, called PRoSIT system, to automatically identify the RoDI of high level of severity at hospital discharge.
Glial fibrillary acidic protein (GFAP)-Immunoglobulin G (IgG) have recently been described as a biomarker of a novel inflammatory central nervous system (CNS) disorder, termed autoimmune GFAP astrocytopathy. Thus far, four major clinical series have been published (two from Mayo Clinic USA, one from Italy and one from China). GFAP-IgG detected in serum or in cerebrospinal fluid, by tissue-based assay and confirmed by cell-based assay, are associated with encephalitis or meningoencephalitis of acute or subacute onset, less frequently with myelitis or optic disk edema. The characteristic MRI feature is brain linear perivascular radial gadolinium enhancement in the white matter perpendicular to the ventricle, consistent with the immunohistochemical staining pattern of GFAP in rodent brain sections. Approximately 20% of reported cases are associated with a neoplasm (ovarian teratoma mostly). Coexisting neural autoantibodies are described in some patients, N-methyl-D-aspartate (NMDA)-receptor (R)-IgG mostly, followed by aquaporin 4 (AQP4)-IgG. The disease is usually corticosteroid responsive although relapse can occur. In contrast, Chinese patients display poorer outcomes. Pathophysiology is not well understood but the intracellular antigen location makes GFAP-IgG unlikely pathogenic whereas animal models and neuropathologic data suggest a T-cell immune-mediated disorder. The aim of the investigators is to report the first French cohort of patients GFAP-IgG positive. Investigators retrospectively assessed clinical, immunological and radiological features, treatment response and outcomes.
Reversible Cerebral Vasoconstriction Syndrome (RCVS) is a syndrome described at the end of the 20th century. Generally, it has a benign course. It is revealed by acute headaches, in different circumstances such as sexual activity, physical exertion or emotional disturbances. But, in few cases, it might be complicated by seizure, stroke and subarachnoid haemorrhage. The diagnosis is confirmed on radiological examination, which shows diffuse cerebral vasoconstriction of brain vessel. It calls reversible because at three month, vasoconstriction disappears. Most cases occur during post partum or after serotoninergic/adrenergic drug use. The pathophysiology is unknown but a transient disturbance in the control of cerebrovascular tone by sympathic hyperactivity and/or endothelial dysfunction are suspected. The assessment of endothelial dysfunction in brain is possible with transcranial doppler. Chen et al. showed an impairment of vasodilatation post apnea induced called BHI on RCVS subjects compared with healthy control. BHI is a reflect of endothelial function in brain. Currently, investigators do not know if endothelial dysfunction occurred only in brain or if it may occur in systemic vessel. Some case reports talk about systemic complication such as kidney infarct or hepatic arterial vasospasm so a systemic vascular dysfunction may be suspected. In this study, researchers will study systemic endothelial function by measure of the pulse wave velocity during RCVS and after its recovering at 3 months, and compare it at healthy controls.
