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 objective of this project is to evaluate the presence of melanoma quiescent or initiating clonal cells in peritumoral healthy tissue displaying the same molecular signature than those of the tumor/metastasis and to correlate this presence to the prognostic value.
The sequence type 131 (ST131) is a predominant lineage among extraintestinal pathogenic Escherichia coli. It plays a major role in the worldwide dissemination of E. coli that produce extended-spectrum beta-lactamase (ESBL). The aim of this study was to describe the epidemiology of ESBL producing ST131clonal group in our university hospital. All patients with an infection due to ESBL E. coli will be prospectively included for a 2-year period. ST131 isolates will be identified and risk factors associated to ST131 will be determined in comparison to non-ST131 ESBL E. coli.
This prospective, randomized, open-label and multicenter phase III study is aimed to estimate the survival benefit of Early Palliative Care (EPC) combined with standard oncology care including first-line chemotherapy (experimental arm) over standard oncology care only (standard arm), in patients with metastatic upper gastrointestinal cancers (gastric cancer, pancreatic cancer, biliary tract cancers).
Splenic Marginal Zone Lymphoma (SMZL) is a well-defined low-grade B-cell lymphoma,considered as a rare neoplasm accounting for about 2% of all non-Hodgkin's lymphomas (NHL) and represents for most cases of otherwise unclassifiable chronic lymphoid B-cell cluster of differentiation antigen 5 (CD5)-lymphoproliferative disorders. SMZL is characterized by an almost exclusive involvement of the spleen and bone marrow and in about 25% of cases the disease pursues an aggressive course and most patients die of lymphoma progression within 3-4 years. Retrospective studies have indicated that purine analogous achieved very high response rates in both naïve and pre-treated patients. Moreover, the introduction of the anti-cluster of differentiation antigen 20 (CD20) humanized antibody rituximab, either used alone or in combination with chemotherapy has been reported to be very effective in producing a rapid clearance of neoplastic cells.
Intravenous high-dose amoxicillin is a frequently prescribed antibiotic in intensive care units and infectious disease departments, in such indications as meningitis, endocarditis, listeriosis, or documented susceptible osteo-articular infections. Among possible side effects is the occurrence of amoxicillin crystalluria. Its incidence is unknown. It is deemed uncommon but literature is poor and its incidence is probably under-estimated. It can be complicated with hematuria or acute renal failure and may require renal replacement therapy. measures that can limit the impact of this nephrology crystalluria. Since the beginning of 2014, because of the occurrence of a case of macroscopic crystalluria in our unit and a pharmacovigilance alert, it has been decided to search systematically for amoxicillin crystalluria in several centers of the north-east of France. The investigators propose to study these patients, through an observational study of a multicenter longitudinal cohort, to assess the incidence of amoxicillin crystalluria during high dose intravenous amoxicillin treatment.
Cerebral palsy (CP) is a group of non-progressive motor dysfunction but often changing, secondary to injury or brain abnormalities that occur in early stages of development. In children with CP, the brain injury lead to a delayed motor development in the first weeks, associated with muscular spasticity. Drug treatments include oral treatments (baclofen and tizanidine) and injectable treatments like Botox (intramuscular injection) and neurolysis with alcohol or phenol (local injection into the nerve). Regarding botulinum toxin, there is no study questioning its effectiveness. However, no publication on the pathophysiology of human muscle of the CP child after toxin injection was found. The action of the toxin on the neuromuscular junction (NMJ) and muscle structure is unknown in children with CP. The primary objective of this study is to describe structural abnormalities of the CP child's muscle following multiple toxin injections in terms of NMJ fragmentation and axonal sprouting. Secondary objectives: To evaluate the relationship between: - The severity of the motor impairment and muscle structural abnormalities. - The clinical measure of spasticity and muscle structural abnormalities. - To compare the structure spastic muscles with toxin injections and spastic muscle without toxin injections For muscles with multiple toxin injections, assessing the relationship between : - The number of toxin injections and muscle structural abnormalities. - The date of the first injection and muscle structural abnormalities. - The total dose of injected toxin in the muscle and its structural abnormalities. - The nature of the product injected in the muscle and its structural abnormalities. This innovative study will improve the knowledge on the effects of long-term botulinum toxin injections on the muscle (and therefore its safety in usual care), on the spastic muscle NMJ of CP children, on the pathophysiology of the CP child's muscle. All the visits all acts will be performed according to usual patient follow-up. Only a biopsy will be performed in addition, taken from an injected muscle during a planned operation. A biopsy may also be performed on a muscle without toxin injection if the act is made possible by the planned surgery. No biopsy will be made on a muscle that would not require surgery.
Multiple Myeloma (MM) is a malignant proliferation of monoclonal plasma cells. Myeloma accounts for almost 14% of all hematologic cancers and is essentially incurable. Myeloma commonly evolves from a precursor disease, Monoclonal gammopathy of undetermined significance (MGUS). Despite intensive study, the etiology of MGUS and myeloma are unknown and no lifestyle or environmental exposure factors have been identified that are consistently linked to increased risk of MM, MGUS or the transition between the two. The overall goal is to identify risk genes for dysglobulinemia, and more specifically Multiple Myeloma. This will involve the conservation of cells in a bank and genetic sequencing on samples obtained from families with at least two cases of dysglobulinemia. Material used for sequencing is likely to include fresh peripheral blood cells or lymphoblastoid lines established from peripheral blood lymphocytes of patients.
The aim of the study is to evaluate if the plasma activity of the tissue factor at the time of the diagnosis of a lung cancer, before any treatment, or after the treatment of induction (surgery or two first cures of chemotherapy), can be a predictive factor of venous thromboembolism disease in the year which follows the diagnosis, independently of the other parameters.
In this diagnostic study, the aim is at evaluating the diagnostic accuracy of MRI (Magnetic Resonance Imaging) to detect allergic broncho-pulmonary aspergillosis in patients with cystic fibrosis.
Despite a large diffusion for generic anti-hypertensive, they are not currently used. Clinical validation studies could be better to convince users and prescribers than pharmacologic validation only. A pragmatic study to evaluate generic anti-hypertensive efficacy is proposed. It takes place in real conditions of care for hypertensive patients, for a manometer control criteria. The aim of the study is to test the hypothesis of non-inferiority for generic anti-hypertensive for blood pressure control.
