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.
Relapse remains the main cause of death in patients with myeloid malignancies, especially after an allotransplant. Using drugs with higher anti-leukemic activity as part of the conditioning regimen is one of the strategies to decrease relapse incidence in this population. Retrospective studies have shown that clofarabine can achieve impressive results compared to the use of fludarabine in acute myeloid leukemia (AML) as part of the conditioning regimen. Confirming such results in a prospective manner would definitely establish the CloB2A2 as a superior reduced-intensity conditioning (RIC) regimen compared to the FB2A2 for AML patients.302 AML patients (151 in each arm) in complete remission at transplant will be included with the main objective to demonstrate a significant better 2-year overall survival for CloB2A2 cases (70% vs 55%). A cost-utility analysis and a cost-effectiveness analysis will be also performed as well as an assessment of the quality of life after transplant. Clofarabine will be furnished to all centers. The duration of the study will be 5 years with 3 years of inclusion and 2 years of follow-up for each patient.
The goal of this clinical trial is to test the MEX-CD1 hemodialysis medical device in patients suffering from Wilson's Disease. The main questions it aims to answer are: - Does the device work as expected by removing the excess of free copper from the blood? - Is the device safe when used according to the instructions for use? Depending on the severity of their symptoms, patients will receive either 5 or 10 treatments on consecutive days with the MEX-CD1 hemodialysis medical device.
The ability of an individual to conceive some alternative representations and to behave in a flexible manner would emerge from preschool age and drastically improve between the ages of 3 and 5 (Doebel and Zelazo, 2013). They constitute, according to Diamond (2013), a prerequisite for the development of the Theory of Mind (ToM). Deficits in Executive Functions (EF) may therefore interfere with the child's ability to understand and adapt to social situations. Treatment failures are often observed when traditional cognitive tools are used. This would be linked to the divergence between non-immersive tests and situations encountered in everyday life (Damasio, 1994; Priore Castelnuovo and Liccione, 2002). For this reason, an increasing number of researchers are using virtual reality for the rehabilitation of executive functions and Theory of Mind in patients with neurodevelopmental pathology (Millen, Edlin-White and Cobb, 2010) or brain damage (Le Gall, Besnard, Louisy, Richard and Allain 2008). There is currently no systematic evaluation of ToM in children with the infantile form of DM1 even though these abilities are considered particularly vulnerable and have a decisive impact on the subsequent development of interpersonal relationships. This research will focus on studying the socio-emotional disorders associated with the infantile form of Myotonic Dystrophy type 1 (DM1). The axis that we propose to develop more specifically will be an interventional study with the aim of remediation with children from 5 to 16 years old suffering from the infantile form of DM1 via a training protocol in low-immersion Virtual Reality (VR) centered on emotional processing and theory of mind.
Sarcoidosis is a systemic inflammatory disease characterized by unspecific granuloma formation. Our hypothesis is that granuloma formation and maintenance mainly relies on the overactivation of monocytes (Mo) and macrophages (Ma). To this end, the study aims (i) to define MoMa systemic signature in sarcoidosis, (ii) to characterize this signature in situ on tissue samples, and (iii) to identify causative factors that participate to the MoMa chronic overactivation. Thus, a cohort of sarcoidosis patients will be compared with tuberculosis patients. The MoMa systemic signature will be defined on whole blood (TruCulture model) and then in situ through different methods (multi-parameter spectral flow cytometry, RNA-seq, Luminex, imaging mass cytometry). The epigenome of monocytes will be studied thanks to CUT&Tag. The MoMa systemic signature will be defined ex vivo at different time points during the course of the disease with phenotypic, transcriptomic, cytokine and functional approaches. The previously identified signature will be studied in situ and completed by the characterization of granuloma architecture and microenvironmental interactions, which could be modulated by epigenetic modifications. Hence, the epigenome of monocytes will be analyzed in two groups (sarcoidosis and tuberculosis). These results would allow to better understand sarcoidosis physiopathology and, in fine, may raise new therapeutic strategies. Finally, the study could challenge the dogma on innate immunity/auto-inflammation versus adaptive immunity/auto-immunity/memory.
The research aim to study in detail the motor, cognitive and affective modifications of Parkinsonian patients (compared to control subjects) at a moderate stage of the disease and to analyze by positron emission tomography (PET) imaging with the specific radioligand [11C]SB207145 the expression levels of this 5-HT4 receptor. At the same time, the study will monitor the impact of the 5-HTTLPR polymorphisms of Serotonin Transporter (SERT) and Brain-derived neurotrophic factor (BDNF) Val66Met on the expression of the 5-HT4 receptor in subjects.
The Stanislas Cohort is a monocentric familial longitudinal cohort originally comprised of 1006 families consisting of two parents and at least two biological children and deemed healthy, recruited in 1993-1995 at the Centre for Preventive Medicine of Nancy. This cohort was established with the primary objective of investigating gene-gene and gene-environment interactions in the field of cardiovascular diseases. The 5th visit of the STANISLAS Cohort will allow a better evaluation of the cardiovascular ageing of the population and the transition toward cardiovascular or renal diseases in relation with their genetic profile and environment.
Frequency of Inflammatory Bowel Diseases in children (IBD)-Crohn's disease (CD), Ulcerative colitis (UC) is constantly increasing. Pediatric-onset IBD represent a different nosological entity (from adult IBD) because of their major inflammatory activity, their significant anatomical extent and their stenotic and/or fistulizing character sometimes from diagnosis. Intestinal lesions are due to dysregulation of the intestinal immune system but the cause is unknown. The investigators hypothesize that extranuclear DNA participates in the amplification of the inflammatory response at the intestinal and blood levels during pediatric IBD through the cGAS-STING pathway. The investigators will analyse blood and fecal samples, and colonic biopsies issued from ill children and control participants on age of 6 to 17 years. The investigators think that this study will provide a better understanding of the mechanisms involved in pediatric IBD, assess the place of the cGAS-STING pathway, identify potential biomarkers of pediatric IBD and new potential therapeutic targets based in particular on the inhibition of the cGAS-STING pathway.
The benefits of breastfeeding no longer need to be proven. Many studies have shown its positives effects on both infants and mothers. Exclusive breastfeeding is thus recommended within the first six months of life. Excessive screen use has been shown to be harmful in many aspects of daily life. The impact upon the relation between mother and newborn infant is poorly studied. The study aims to evaluate the impact of the use of smartphones on the success and duration of breastfeeding.
Rhizarthrosis (trapeziometacarpal osteoarthritis) is the most common primary osteoarthritis of the hand, and a source of major functional impact, as it affects the thumb. Non-surgical therapeutic means are currently limited to wearing an immobilization splint, analgesics and oral non-steroidal anti-inflammatory drugs. These symptomatic treatments are of limited effectiveness and do not prevent from progression of the osteoarthritis disease. The most effective treatments currently recognized are surgical, but they also have their limits. Cell therapy is considered as a promising approach to treat tissue damage including osteoarthritis. Mesenchymal stromal cells are excellent candidates for achieving this type of result, because they can differentiate into the different tissues from the mesoderm (cartilage, bone, muscle, tendons, fat, dermis, conjunctive matrix, etc.). In addition, unlike cells from the embryonic cord, the risk of teratoma or tumor does not exist. Mesenchymal stem cells have regenerative and immunomodulatory properties but the methods of collection, preparation, combination with substances such as hyaluronic acid, or PRP, or platelet concentrates, will obviously influence the effectiveness of the results. . Nanofat autografts are obtained in a simple way, in a closed circuit, preserving the stromal mesenchymal cells in large numbers with a minimum impact on the cellular elements. The preparation remains simple and inexpensive, but it is nevertheless necessary to characterize these emulsified preparations biologically before using them as cell therapy. The main objective of this study is to characterize a nanofat autograft on a biological level.
Researchers are looking for a better way to help people with any known or suspected problems (except brain or spinal cord-related problems) scheduled for a "contrast-enhanced" Magnetic Resonance Imaging (MRI). MRI is used by doctors to create detailed images of the inside of the body to identify health problems. Sometimes doctors need to inject contrast agent into a patient's vein to perform a so called "contrast-enhanced" MRI (CE-MRI). Such CE-MRI examinations may support doctors to identify certain health problems or improve the evaluation. The contrast agents commonly used in MRI are gadolinium-based contrast agents (GBCAs). GBCAs contain a "rare earth" element called gadolinium (Gd). Gadoquatrane is a new contrast agent under development with a lower amount of Gd needed per CE-MRI. The main purpose of this study is to learn whether CE-MRI scans with gadoquatrane work better than MRI scans without the use of a contrast agent (GBCA). The researchers will compare the ability to detect known or suspected problems (except brain or spinal cord-related problems) with gadoquatrane-MRI scans to plain-MRI scans without the use of a contrast agent. The participants will undergo 2 MRI scans, one with gadoquatrane and one with currently used GBCA. Both contrast agents will be injected into the vein. Each participant will be in the study for between 6 and 42 days with up to 7 doctor visits. At the start or during the study, the doctors and their study team will: - take blood and urine samples - do physical examinations - check blood pressure and heart rate - review the MRI scans obtained in the study and decide on the diagnosis - ask the participants questions about how they are feeling and what adverse events they are having. An adverse event is any medical problem that a participant has during a study. Doctors keep track of all adverse events, irrespective if they think it is related or not to the study treatments.
