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 investigator would like to create a prospective cohort of patients in order to describe eosinophilic esophagitis with the specificities corresponding to our geographical territory, and to study their evolution at 3 months, 6 months, 12 months, 18 months and 24 months. This study would also enable us to investigate the quality of life of these chronically ill patients
The objective of this prospective international cohort is to evaluate the LUMENEYE rectoscope for assessment on tumor response after total neoadjuvant treatment in rectal cancer. Patients included in this study will be patients who initially will be good candidates for organ preservation. The participating centers are all expert centers in tumor assessment. All patient assessments after neoadjuvant treatment for rectal adenocarcinoma will be included in each centre.
Patients with IBD experience complex therapeutic pathways. The development of new treatments, more effective and free of side effects, is a therapeutic need. However, such therapeutic innovations can only be effective if they are accepted by the target populations. The objective of this study is to analyze, in patients with chronic inflammatory bowel diseases, the acceptability of 4 different treatments: chemically modified bacteria treatment, genetically modified bacteria treatment, probiotics, and fecal microbiota transplantation. The acceptability of the treatments, i.e. the patients' responses and their rationalizations, will constitute the evaluation criterion and the result of the research. This study will also allow us to evaluate the impact of IBD on quality of life and well-being. Research factors associated with quality of life and well-being, based on dedicated questions (scales validated and included in the questionnaire), evaluate the differential acceptability of the 4 treatments studied. Finally, cross-analyses between health, socio-demographic factors, quality of life and well-being will be performed.
Under the impetus of governing bodies, learned societies, hospital management, CPPs, etc., clinical research has developed and structured considerably, in order to provide the medical community and patients with the most appropriate care, and to formulate recommendations. In anesthesia, clinical research evaluates drugs, medical devices or care pathways. However, the general public's perception of this research in our specialty remains confidential. Several studies carried out in oncology have shown limited interest in research on the part of the general public and patients, and more often than not a lack of awareness of ethical laws and the role of french ethics committee (CPP). By means of an anonymous questionnaire handed out at the anesthesia consultation, the investigators would like to assess patients' level of knowledge of clinical research in anesthesia, and find out how they feel about the possibility of being included in a trial.
Calcium Release Deficiency Syndrome (CRDS) is a novel inherited arrhythmia syndrome secondary to RyR2 loss-of-function that confers a risk of sudden cardiac death. Diagnosis of CRDS presently requires cellular-based in vitro confirmation that an RyR2 variant causes loss-of-function. We hypothesize that CRDS can be diagnosed clinically through evaluation of the repolarization response to brief tachycardia, mediated by cardiac pacing, and a subsequent pause.
Modifiable stroke risk-factors, which include poor lifestyle habits, account for 90 % of the risk of stroke. Disability Adjusted Life Years (DALYs) related to cerebrovascular disorders rely on three main factors, including the severity of stroke-related symptoms, the occurrence of stroke complications, and stroke recurrences. Stroke complications and the risk of stroke recurrence are highly dependent on the control of vascular risk factors. Thus, the secondary prevention of stroke involves profound lifestyle modifications including substance use cessation and diet changes.
Mast cell disorders constitute a heterogeneous group of diseases, including : - mastocytosis, i.e. cutaneous, indolent and severe forms of the disease, such as aggressive mastocytosis and mast cell leukemia) ; - mast cell-associated diseases such as mast cell activation syndrome (idiopathic, secondary or clonal), affecting both children and adults. No epidemiological data are currently available in France. In France, medical care of mast cell disorders is mainly provided by a rare disease network (CEREMAST), whose CRMR is located at the Necker Enfants Malades hospital in Paris. A total of 20 centers are located throughout France. Our aim is to use this network to study patients suffering from these diseases. The overall aim of the study is to improve the understanding, diagnosis, prognosis, recognition and management of patients with mastocytosis.
This is a national clinical trial, multicentric (28 centers), non-randomized phase 2 study. Population: Patients with previously untreated Richter's syndrome (RS), defined as the occurrence of an aggressive lymphoma (of diffuse large B-cell lymphoma histology) in a patient with chronic lymphocytic leukemia (CLL). Study treatment: The duration of each cycle is 21 days. Cycle 1: Participants will receive standard of care doses of R-CHOP in cycle 1 as follows: - Rituximab 375 mg/m² IV Day 1 - Cyclophosphamide 750 mg/m² IV Day 1 - Doxorubicin 50 mg/m² IV Day 1 - Vincristine 1.4 mg/m² [capped at 2.0 mg] IV Day 1 - Prednisone 60 mg/m2 per day PO Day 1-5 Cycle 2: In order to minimize cytokine release syndrome (CRS), participants will then receive G-CHOP as cycle 2 (with obinutuzumab) and glofitamab: - Obinutuzumab 1000 mg single dose IV Day 1 - Cyclophosphamide 750 mg/m² IV Day 1 - Doxorubicin 50 mg/m² IV Day 1 - Vincristine 1.4 mg/m² [capped at 2.0 mg] IV Day 1 - Prednisone 60 mg/m2 per day PO Day 1-5 - Glofitamab : administered intravenously (IV) as a step-up dose on Days 8 (2.5 mg) and 15 (10 mg) Cycle 3-6: Participants will receive standard of care doses of R-CHOP and Glofitamab as follows: - Rituximab 375 mg/m² IV Day 1 - Cyclophosphamide 750 mg/m² IV Day 1 - Doxorubicin 50 mg/m² IV Day 1 - Vincristine 1.4 mg/m² [capped at 2.0 mg] IV Day 1 - Prednisone 60 mg/m2 per day PO Day 1-5 - Glofitamab : 30 mg IV Day 8 Cycle 7 and 8 (only for patient in Complete Response or Partial response after Cycle 6): Cycle 7 and 8 consist of 2 infusions of glofitamab only at D8C7 and D8C8: ● Glofitamab : 30 mg IV Day 8 Primary endpoint Percentage of participants with a complete response as assessed by the investigator using the Cheson IWG 2014 Lugano Classification (i.e. Deauville scale 1-3) after 6 cycles of R/G-CHOP + glofitamab or at permanent treatment discontinuation. End of treatment is defined as after 6 cycles of R/G-CHOP + glofitamab. Permanent treatment discontinuation is defined as the discontinuation of all treatments (R/G-CHOP, glofitamab).
The management of rheumatoid arthritis is based on the prescription of disease-modifying anti-rheumatic drugs (DMARDs) to induce clinical and biological remission. If the first line of treatment (methotrexate) fails, a biotherapy may be prescribed. In daily practice, the initiation of a targeted therapy must therefore be based on the prescriber's expertise or qualification in terms of his or her level of experience in the diagnosis and management of chronic inflammatory rheumatic diseases such as rheumatoid arthritis. As the therapeutic arsenal has expanded, so has the question of choosing the right treatment for the right patient at the right time. At present, in daily practice, there is no tool to help clinicians predict treatment efficacy. The choice of biotherapy based on efficacy carries relatively little weight, firstly because this choice is made in relation to other biotherapies, and secondly because there are no superiority studies that have actually demonstrated greater efficacy in favor of one of the targeted therapies. In the age of Big Data, artificial intelligence can be used to develop algorithms for predicting treatment response. mYXpression has developed medical decision support software based on the integration of transcriptomic markers to assess the probability of response and/or non-response to biotherapies for each patient. The algorithm's performance was theoretically tested by retrospectively collecting transcriptomic data and clinical responses to 6 biotherapies from 992 patients included in 17 clinical trials or cohorts. The aim of this observational study is to demonstrate the value of PEAR 2.0 medical decision support software in the management of rheumatoid arthritis patients who are candidates for biotherapy.
Percutaneous pulmonary valve revalvulation (PPVR) has emerged as an alternative to surgery for the treatment of congenital heart disease with right ejection pathway dysfunction. The Melody valve (Medtronic Inc., Minneapolis, Minnesota) was the first to be used, validated in 2006 by the European Commission and in 2010 by the Food and Drug Administration (FDA). Subsequently, the Sapien valve (Edwards SAPIEN pulmonic transcatheter heart valve, Edwards Lifesciences, Irvine, California) was subsequently approved for PPVR (Europe, 2010; FDA 2016). Infective endocarditis (IE) after PPVR is currently a major concern with an incidence after Melody PPVR estimated at 3%, much higher than the rate of prosthetic left-heart IE. The Sapien valve has been introduced more recently and some cases of IE have been published. Despite the attention this issue is receiving, there are few studies of sufficient size or statistical power to elucidate the risk factors for developing an IE after PPVR according to the type of valve implanted. Recently, a multicenter study was published by the American team of McElhinney et al (J Am Coll Cardiol 2021 ; 78 :575-589). Although it was a sizeable cohort (2476 patients), there was a large disparity in the ratio of patients who underwent revalvulation with either the Melody or Sapien valve, in favor of Melody patients (2038 Melody patients vs. 438 Sapien patients). In this study, the estimated risk of IE was higher for patients who received a Melody valve, according to univariable analysis but not anymore after multivariate analysis. To further answer this question, we develop an international retrospective multicenter registry whose main objective will be to characterize the incidence rate of infective endocarditis after percutaneous pulmonary revalvulation according to the type of valve implanted (Melody vs. Sapien) using a large population of patients with comparable characteristics (match-population).
