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.
Moya Moya disease or syndrome ar characterized by a progressive or occlusion of the intracranial carotid arteries and their mainproximal branches, followed by the development of fragile neovessels at the base of the skull, leding to a high risk of both ischemic and hemorragic stroke over time. Moya Moya syndrome are associated to a variety of disease, which main frequent is sickle cell disease (SCD). Among patients with SCD who had suffered from at least one ischemic stroke, the prevalence of moya moya syndrome was estimated up to 43%. In general, therapeutic strategies in Moya Moya to prevent first ever ou recurrent stroke can be divided into conservative medical treatment and surgical revascularisation (direct bypass, indirect bypass or combined bypass). The aim of this study is to compare prognosis of patients with Moya Moya syndrome associated with sickle cell disease or not. The investigators retrospectiveluy analysed medical chart from 2010 to 2021 of patients with Moya Moya disease or syndrome at two French university hospitals (including a center of the french West Indies where prevalence of sickle cell disease is high). The diagnosis was based on angiography or MRI records showing uni- or bilateral stenosis of distal intracranial internal carotide arteries or middle cerebral arteries associated wirh classic collateral network. Main endpoint will be comparison of a composite outcome defined as time from Moya Moya diagnosis to first or recurrent stroke or bad prognosis achivement (defined by modified Rankin score >2)
The purpose of this clinical research study is to learn more about the use of the study medicine, volixibat, for the treatment of pruritus (itching) associated with Primary Biliary Cholangitis (PBC), and to assess the possible impact on the disease progression of PBC.
The purpose of this study is to characterize the safety and tolerability of talquetamab when administered in different combination regimens and to identify the safe dose(s) of talquetamab combination regimens.
The clinical practice recommendations highlight the fact that the patient's choice concerning the management of her aborted pregnancy in the first trimester should be privileged, after clear and appropriate information on the available treatments, in order to improve his experience and reduce the negative psychological symptoms that can generate an alteration in the quality of life, in the aftermath of the loss of pregnancy. The present study will describe the efficacy, satisfaction and tolerance of patients benefiting from medical treatment with Mifégyne® and MisoOne® versus those benefiting from surgical treatment by endo-uterine aspiration for the management of a pregnancy stopped during the first trimester at the Toulouse University Hospital
Obstructive sleep apnea syndrome (OSA) is a common condition associated with major repercussions such as excessive daytime sleepiness and impaired quality of life as well as metabolic and cardiovascular complications. Continuous positive airway pressure (CPAP) remains the treatment of choice but its effectiveness remains limited, especially in reducing cardio-metabolic risk. Interventions to modify the lifestyle are therefore recommended in the management of OSA. The emergence of information and communication technologies is an opportunity for patients to have tools that promote self-management and behavioral changes. The recent development of telerehabilitation (TR) is a promising approach that has only been the subject of pilot studies. In a randomized, controlled and multicenter study, we propose to test the hypothesis according to which the use of a mobile TR solution, associated with continuous positive airway pressure (CPAP), will allow obese patients to adopt behavioral modifications to improve markers of severity of OSA. The analysis of big data (data-mining) will allow a better understanding of the motivational obstacles and levers.
Immersion Pulmonary Edema (IPE) is a relatively new form of hemodynamic pulmonary edema. The number of cases has been increasing over the last ten years and it has become the second most common cause of hospitalization for military divers, after decompression sickness. The pathophysiological mechanisms of IPE are not completely known. Its occurrence is linked to a combination of factors related to the environmental constraints of diving, as well as to the diver's equipment. The main external factors are increased hydrostatic pressure, cold, intense effort and emotional stress. The impact of internal factors is not known. At this time, no severe forms of IPE have been identified in the military. However, it is important to identify this pathology at an early stage, even if the signs appear minor, because the continuation of underwater activity can significantly worsen the clinical picture. The risk of recurrence (greater than 15%) could result in a severe or even lethal accident.
To assess the prevalence of renal disease in a pediatric population of patients with celiac disease by looking for the presence of hematuria and/or proteinuria.
The purpose of this study is to evaluate treatment persistence with guselkumab and interleukin-17 inhibitor (IL-17i) initiated at enrollment into this study (PsABIOnd).
After exiting the RACE trial (NCT02099747) patients will be invited to participate in this long term follow-up study
Platelets are primarily known for their central role in primary hemostasis. However, they are increasingly recognized for their participation in various non-hemostatic processes, such as cancer progression and clinical expression. Experimental and clinical data indicate that the involvement of platelets in the pathophysiology of cancer goes far beyond the realm of cancer-associated thrombosis. Several experimental studies have shown that platelets can promote the metastatic process by various mechanisms. However, while it has been shown in vitro that direct contact with platelets initiates tumor cells for metastasis, it remains unclear whether such contacts occur in solid tumors. In addition to their ability to promote metastasis, platelets have been shown to stimulate angiogenesis and play a crucial role in lymphangiogenesis. Considering that blood vessels, lymphatics and immune cells are major components of the tumor ecosystem, our hypothesis is that platelets contribute to the development and / or regulation of the tumor microenvironment. This is because platelets stabilize tumor blood vessels by permanently repairing vascular damage caused by immune cells infiltrating tumors. Targeting platelets destabilizes tumor vessels, causing intra-tumor hemorrhage, which allows intra-tumor accumulation of intravenously administered anti-tumor drugs such as paclitaxel and improves their efficacy. Studies have also reported the role of platelets in several pathogenic mechanisms of cancer: thrombocytosis is a paraneoplastic syndrome which suggests a poor prognosis in patients with solid tumors; a negative correlation between the platelet count and the response to chemotherapy has been reported in several types of cancer; histological analyzes of esophageal cancer suggested a possible association between the presence of platelets in the tumor stroma and the level of tumor lymphangiogenesis and lymphovascular invasion; finally, a recent study reported the expression of one of the main targets of immunotherapies, PD-L1, on the platelets of patients suffering from different types of solid cancers. All of these data support our hypothesis that platelets are components and / or regulators of the tumor microenvironment and therefore potential targets for the improvement of anti-tumor therapies. In this context, the objectives of our project are to determine whether platelets are components of the microenvironment of tumors of the central nervous system, and to study the possible correlations between the intratumoral presence of platelets and the evolution of patients with central nervous system tumors
