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.
Prostate cancer represents the 1st diagnosed cancer in men, with 50400 new cases and 8100 deaths in 2018. Improved diagnostic and therapeutic strategies have led to a 3.7% decrease in mortality between 2010 and 2018 with a 5- and 10-year survival rate of 93% and 80%, respectively. Pelvic conformal radiotherapy is an important therapeutic technique in the management of pelvic cancers, particularly prostate cancer. However, despite the improvement in radiation techniques, this technique is responsible for acute and late adverse events at the bladder level, these symptoms being grouped under the term radiation cystitis. It has a clear impact on the quality of life of patients. Acute radiation cystitis is likely to occur during treatment or within 3 months after radiotherapy. Its incidence is estimated at nearly 50%. The late form appears on average 2 years after radiation, but can sometimes occur 10 or 20 years later. Its incidence is 5 to 10% of cases. Although certain factors have been identified, such as the dose received, fractionation or comorbidities, the pathophysiology of radiation-induced cystitis remains unclear, particularly because of the risks of complications arising from access to bladder tissue post-irradiation, thus limiting our knowledge as well as the therapies targeting this process. The use of biomarkers in liquid biopsies allows us to understand the problem of access to irradiated tissues and to highlight protein changes, prognostic of radiation-induced visceral toxicity. Few works are published on the evaluation of inflammatory and pro-fibrotic biomarkers of radiation-induced cystitis in liquid biopsies. Only 2 retrospective studies have shown a correlation between late radiation cystitis and increased levels of plasminogen activator inhibitor 1 (PAI-1), matrix metalloproteinase inhibitors (TIMP1 and TIMP2), hepatocyte growth factor (HGF), vascular endothelial growth factor (VEGF) and placental growth factor (PIGF) in urine. However, none of these studies explored the variation of biomarkers in the early stage of radiation-induced bladder toxicity. This would suggest the feasibility of prospective assay of overexpression of these proteins in liquid biopsies.
The justification of this prospective and multicenter study is based on the absence of published data concerning, status epilepticus (SE), a pathology which seems frequent in the French West Indies (FWI) and French Guiana, and whose etiological and prognostic characteristics are often mentioned or assumed but which remain to be demonstrated. The scientific interest lies both in the knowledge of the epidemiology of this pathology and in the identification of the main etiologies, in particular the underlying brain lesions. The morbidity of SE is significant, associating neurological disorders with impaired consciousness, respiratory, hemodynamic and cardiac rhythm disorders, as well as metabolic disorders such as acidosis. SE-related mortality in the acute phase ranges from 3-40% across studies and regions, while long-term mortality ranges from 17-80% depending on age, cause of SE, comorbidities and the occurrence of complications. The prognosis of this pathology has however improved in recent years in developed countries or countries with a high level of health system. On the other hand, the morbidity and mortality of SE in the French overseas departments is not known, even if these territories are supposed to be at an equivalent level in terms of health system to that of mainland France.
Giant cell arteritis (GCA) is the most common vasculitis in adults. The diagnosis of GCA is evoked by the association of clinical signs and biological anomalies (inflammatory syndrome) in patients over 50 years of age. On the other hand, starting a treatment implies being certain of the diagnosis which requires performing a temporal artery biopsy under local anesthesia. This examination is therefore an invasive procedure for patients whose sensitivity is not optimal. This is why imaging techniques (echo-Doppler or MRI of the temporal arteries) have been developed to look for signs of vasculitis without the need to perform a biopsy. However, these examinations lack sensitivity (=falsely concluding the absence of GCA) and specificity (=falsely concluding the presence of GCA). Recently, advances in imaging, and in particular positron emission tomography (PET), have made it possible to visualize the cephalic arteries, including the temporal artery. The aim of this study is therefore to evaluate the sensitivity and specificity of PET of the cephalic arteries for the diagnosis of GCA and to compare them with those of echo-Doppler and MRI of the temporal arteries.
The purpose of this study is to collect medical informations and samples from refractory and/or relapsed chronic lymphocytic leukemia during or after venetoclax treatment, in order to evaluate the frequency of resistance mechanisms.
Digestive NETs are the second most common malignant digestive tumor after adenocarcinoma. The most common gastrointestinal NETs arise from the small intestine. These tumors have a high lymph node and distant metastatic potential (hepatic, pulmonary, etc.). Their management is essentially surgical and the extent of the resection essentially depends on preoperative data from conventional and isotopic imaging. The goal of surgical resection is to remove the portion of the small intestine carrying the tumour(s) with healthy margins (so-called R0 resection) and affected lymph nodes in the mesentery (lymph node dissection). The extent of lymph node dissection, sometimes significant, exposes you to the risk of short hail with its own complications (malnutrition, diarrhoea, etc.). Consequently, an analysis of the benefits and risks between the interest of an extensive and oncological resection (R0) and the risks of short bowel must be carried out for each patient. The reference examination to define lymph node involvement is determined by the histological examination of the resected surgical specimen (reference examination). The preoperative evaluation of lymph node extension is done by preoperative abdominal CT scan. However, the preoperative CT scan is not always consistent (sensitivity and specificity) with the pathology data (reference examination). For about 5 years, isotopic imaging (DOPA-PET and DOTATOC) has become feasible and could improve the quality of preoperative evaluation of lymph node extension. Consequently, the aim of this study is to determine the contribution of isotopic imaging (DOPA-PET and DOTATOC) in the preoperative evaluation of lymph node extension.
Pseudoxanthoma elasticum (PXE) is a rare, autosomal recessive genetic disease characterized by progressive calcification and fragmentation of elastic fibers in connective tissues. PXE primarily affect the skin, retina and arterial walls. Given the age of onset and progression of the disease, the consequences of PXE affect a large number of patients of working age and are therefore likely to have an impact on their professional career and job retention. To our knowledge, there are no studies on the occupational impact of PXE.
The somatic complications as well as the suicidal risk make Anorexia Nervosa (AN) the psychiatric disease with the highest mortality rate: the standardized mortality ratio is higher than 4 and 1 in 5 patients with AN who dies has committed suicide. Approximately 20% of patients suffering from AN evolves into a chronic form without prolonged remission. These patients are at high risk of serious complications (somatic and psychiatric). The peak incidence of AN lies between 15 and 19 years: patients suffering from severe and resistant AN are therefore mostly young people. At present, there is no treatment for severe and resistant AN. New insights in AN pathophysiology revealed that AN patients develop a kind of "addiction" to thinness which contributes to weight loss despite negative consequences. In parallel, Deep Brain Simulation (DBS) is now widely performed for movements disorders with good results and low morbidity. DBS is also currently under investigations for other indications such as obsessional compulsive disorder or pharmacoresistant epilepsy. Some case series reported promising results of DBS for severe and resistant AN. The aim of this study is to investigate the safety of nucleus accumbens chronic stimulation for patients enduring severe and resistant AN. Secondary objective is to evaluate patient's acceptance of this new treatment.
This is an open label single group, Phase 2, 1-arm study for treatment to evaluate efficacy, safety, and Pharmacokinetic (PK) of tusamitamab ravtansine in nonsquamous non-small-cell-lung-cancer (NSQ NSCLC) participants with negative or moderate CEACAM5 expression tumors and high circulating carcinoembryonic antigen (CEA). Participants who will be enrolled, will receive tusamitamab ravtansine as monotherapy every two weeks (Q2W) until disease progression, unacceptable adverse event (AE), initiation of a new anticancer therapy, or the participant's or investigator's decision to stop the treatment, whichever comes first. A total of approximately 38 participants are planned to be treated.
ENDOmiARN Salive Test is a multicentre external validation study of a salivary signature of endometriosis carried out in France in Obstetrics and Reproductive Medicine departments, in order to evaluate its performance and discuss its use in clinical practice. The clinical application is to significantly reduce the time to diagnosis and improve the care pathway for endometriosis. The study population is made up of women aged 18 to 43 years with formally diagnosed endometriosis or suspected endometriosis who are already receiving either medical (MAP) or surgical treatment as part of their routine care. The patients concerned by the study are managed without any change in the care pathway, nor any change in the therapeutic indications, nor any change in the diagnostic examinations (imaging or biology) required according to the context, which are carried out in accordance with the HAS recommendations. In this study, the management and follow-up of patients : - Are not imposed by the study: the doctor remains free to make medical prescriptions (treatments and examinations) and to determine the interval between consultation visits, - Are not modified in comparison with the usual follow-up, except for the performance of : - Collection of saliva - Electronic collection of the answers to the questionnaires completed by the patient
