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.
Systemic lupus (SL) is a rare chronic autoimmune disease characterized by the production of autoantibodies directed against nuclear antigens, particularly native double-stranded deoxyribonucleic acid (DNA), and excessive production of antiviral cytokines: type I interferons, particularly interferon alpha (IFN-α). IFN-α production results from the excessive detection of nucleic acids (DNA or Ribonucleic Acid (RNA)) by endosomal or intracytoplasmic receptors that are capable of inducing interferon production. The precise mechanisms of cytoplasmic sensor activation remain unknown; however, recent work in the field of interferonopathies suggests a role for human endogenous retroviruses (HERVs). HERVs are remnants of ancient infections caused by exogenous retroviruses integrated into the genome during evolution and represent 8% of the human genome.Several studies have suggested a role for HERVs in the development and maintenance of an excessive immune response in lupus patients and other autoimmune diseases by affecting the type I interferons (I IFN) signalling pathway. To date, none of the approved immunosuppressive drugs for Systemic Lupus Erythematosus (SLE) have been shown to be effective in the background treatment of SL or in preventing relapse. Consequently, there is an urgent need to identify new molecules and therapeutic avenues for disease-modifying therapies. In this study, an innovative therapeutic strategy using a combination of nucleoside reverse transcriptase inhibitors (NRTIs), abacavir/lamivudine, is proposed to treat SLE. Thus, we propose a pilot Phase II, randomized, open-label study using NRTIs in patients with SL in remission or with low clinical activity, and evaluating a biological endpoint (IFN signature), which is a direct proxy for the drug's expected effect. The main objective is to compare the addition of Abacavir/Lamivudine (Add-on) to standard care for 6 months, on the value of the interferon (IFN) transcriptomic signature of patients with systemic lupus with low activity as defined by the Lupus Low Disease Activity State (LLDAS).
Cystic Fibrosis (CF) is a rare hereditary disease with autosomal recessive transmission, affecting 1 in 4700 births in France. Numerous studies have explored the links between oral health and CF, predominantly focusing on a children population. These studies reveal hyposalivation, a risk of dental erosion, an increased prevalence of enamel structural defects, but a reduced prevalence of dental caries in CF children, potentially explained by better oral hygiene. Periodontal disease does not appear to be increased in this population, while the oral quality of life of CF patients has been insufficiently studied. Today, emerging challenges arise due to the increased life expectancy of CF patients, attributed to the rise of modulators such as Kaftrio®, resulting in an adult-majority population in France. The study of periodontal diseases, associated with oral dysbiosis, becomes relevant as they represent bacterial reservoirs that could impact respiratory complications in CF patients. To deepen understanding of the links between oral health and CF, as well as to improve oral health of these patients, it is crucial to update the specific oral profile of this population. A cross-sectional survey using a questionnaire is proposed to include a large number of CF patients in France, aiming for real-life data. This questionnaire is constructed around internationally recognized tools for comparative analysis with normative data. Collaboration with the Patients Association "Vaincre la Mucoviscidose" (VLM) facilitates questionnaire creation, dissemination, and interpretation of results.
ESSURE® is an implantable medical device for definitive and irreversible sterilization indicated for adult women of childbearing age. These implants are inserted into the fallopian tubes by hysteroscopy. Marketed in 2002, ESSURE® contraceptive implants were withdrawn from the French market in 2017 (and worldwide in 2017 and 2018) following the observation in certain patients of polymorphic and non-specific gynecological and extra-gynecological symptoms. Studies with small numbers and short-term follow-up have shown a significant improvement in these symptoms after implant explantation. This constitutes a real public health problem since according to the report of the EPI-PHARE Scientific Interest Group, 198,000 French women have these implants and only 30,000 of them, or 15%, have been explanted, knowing that explantation of ESSURE® implants is recommended only in symptomatic patients. A large number of these patients, presenting symptoms, have not yet been treated for an explant. The physiopathological mechanism(s) is (are) not yet determined but several arguments are in favor of a dissemination of metallic elements contained in these implants whose accumulation could lead to inflammatory and/or allergic and/or autoimmune phenomena. Carrying out a prospective study with long-term longitudinal follow-up appears essential to precisely assess the degree of improvement in the symptoms and quality of life of these patients, determine the most appropriate surgical techniques, and understand the pathophysiological mechanisms that may result in the implementation of specific treatments and relevant markers. From a surgical point of view, there is a real risk of fracture of implants whatever the type of intervention performed: study the biomechanical properties of implants with a view to characterizing their behavior to mechanical rupture but also their thermal resistance in an objective manner seems essential to limit the risk of fracture and help to inform the patient about the surgical technique proposed for explantation. From a biological point of view, the dosage of the metallic elements constituting ESSURE® implants and potentially toxic ones could make it possible to objectify the release of these metallic elements in the body. Analysis of pro-inflammatory cytokines, micro-RNAs (miRNA), quantitative analysis of inflammatory pathway messenger ribonucleic acid (mRNAs) (NanoString technology) and analysis of neuroinflammation by functional imaging should make it possible to explore potential pathophysiological mechanisms. This study responds to a significant request from patient associations.
The goal of this natural history study is to characterize the disease course, characteristics in paediatric population of LAMA2-RD (related dystrophies) patients. The aim of the study is to establish a well-described cohort of patients in France with LAMA2-RD for prospective follow-up and recruitment for future clinical trials. Participants will be follow up during a two years period regarding exhaustive aspects of the pathology: - Muscular function - Respiratory function - Cognitive phenotyping - Quality of life - Growth parameters - Biomarkers
World Health Organization considers non-adherence has a strong negative impact on the health of patients with chronic diseases. In transplantation, adherence to immunosuppressive drug regimens associates with late rejection and graft loss making it a critical determinant of patient outcome. The prevalence of non-adherence in transplant patients, including liver transplant patients, can be as high as 40%. Among others, life-long intake and complexity of immunosuppressive regimen make patients prone to non-adherence. For instance, non-adherence is more prevalent among patients with higher numbers of immunosuppressive drugs. One of the most commonly cited causes of non-adherence is forgetfulness and disruptions in routine, with the evening dose of twice daily regimens being the most likely to be affected6. Besides non-adherence, the constraints generated in everyday life by immunosuppression (including timely and regular drug intake) and the complexity of the immunosuppressive regimens represent a burden for the patients and are probably associated with a health-related quality of life deterioration. Therefore, long-term adherence and quality of life after liver transplantation might be improved by using a well-tolerated and easy-to-handle immunosuppressive regimen. The immunosuppressive regimen after liver transplantation is in most cases based on different combinations of tacrolimus, mycophenolate mofetil and corticosteroids. While corticosteroids are administered once daily, tacrolimus can be administered either twice-daily (BID) as an immediate-release, or once-daily (QD) as an extended-release formulation. Among once-daily tacrolimus formulations, LCP-tacrolimus (ENVARSUS XR®) is approved for the prevention of transplant rejection in adult liver allograft recipients. It has demonstrated similar outcomes compared to immediate-release tacrolimus BID, in both kidney and liver transplantation. Mycophenolate has only been approved for BID administration, preventing from taking all immunosuppressive drugs once daily. Yet, single daily dosing would probably contribute to better adherence and quality of life in patients receiving a life-long treatment. Although the half-life of mycophenolic acid (MPA), the active moiety of mycophenolate mofetil (MMF) is compatible with once-daily administration, no published randomized clinical study has ever evaluated the efficacy and safety of MMF administered QD. The narrow therapeutic index and wide pharmacokinetic variability of tacrolimus and mycophenolate justify individual dose adjustment by means of therapeutic drug monitoring (TDM), in order to minimize the risk of acute rejection and the occurrence of adverse events. For tacrolimus, TDM is generally based on the trough concentration (C0) and sometimes on the area under the concentration-time curve (AUC), while for mycophenolate it should be based on the AUC of MPA. However, the dose adjustment of MMF in liver transplant patients is most of the time performed a posteriori, based on clinical signs of inefficacy of toxicity. Limited sampling strategies with maximum a posteriori Bayesian estimation have been developed by our team for both molecules in adult liver transplant patients to estimate their AUC, which is considered the best marker of exposure for both. Therefore, tacrolimus AUC0-24h can be estimated by Bayesian estimation using samples collected before administration (C0), 8 (C8h) and 12 (C12h) hours after the administration of ENVARSUS XR®, or 1 and 3 hours after the administration of PROGRAF® and ADVAGRAF®. For mycophenolate, the MPA AUC can be estimated using samples collected 20 min, 1 and 3 hours after MMF administration, by Bayesian estimation. Even if limited to 2 or 3 blood samples, tacrolimus TDM for ENVARSUS® requires late sampling (12h post-dose). To overcome the necessity of a longer hospital stay, microsampling devices (MSD) such as the Volumetric absorptive microsampling (VAMS®) device (Mitra®) can be used by the patients to take samples themselves, at home. Moreover, they are less invasive than venipuncture and collect low but accurate volumes of blood for analysis. In this context, we propose a randomized controlled non-inferiority study to demonstrate that in liver transplant recipients, an immunosuppressive strategy based on single daily doses of LCP-tacrolimus (ENVARSUS XR®) and mycophenolate mofetil (CELLCEPT®) started at M6 post-transplantation is not inferior to XR-tacrolimus (ADVAGRAF®) and MMF administered BID, in terms of incidence of treatment failure (see below) at the end of the first year after transplantation, and to obtain adherence, quality of life and safety data. In order to compare solely MMF QD to MMF BID, patients on ENVARSUS XR® and MMF QD will be compared to a third group of patients receiving ENVARSUS XR® and MMF BID. A direct comparison of efficacy and safety, quality of life, adherence and exposure indices will be performed between ENVARSUS XR® and ADVAGRAF®.
The purpose of the study is to compare the effectiveness of Divomed in organising complex hospital discharges with a conventional organisation. Effectiveness will be assessed by reducing the length of stay of patients in geriatric short-stay care.

This is a Phase 2 study, open-label, 2-cohort, multicenter, national, interventional in patients with newly diagnosed multiple myeloma. The study will investigate teclistamab (Tec) in combination with lenalidomide (Len) (Tec-Len; Cohort A) or in combination with talquetamab (Tal) (Tec-Tal; Cohort B), allocated based on minimal residual disease (MRD) status (MRD [-] [standard-risk] vs MRD [+] [high-risk] respectively). The patient population will consist of adults men and women at least 18 years to younger than 66 years of age, who meet eligibility criteria.
The aim of the study is to evaluate the performance of Withings SCT02 with embedded Withings ECG-app in the automatic detection of atrial fibrillation
CAR-T cells (Chimeric Antigen Receptor) are a new immunotherapy, based on the genetic modification of autologous T lymphocytes. CAR-T cell therapy is not devoid of complications. Among the most frequent complications are the risk of infection, cytokine release syndrome (CRS) and neurotoxicity. Nevertheless, some authors have reported serious acute cardiac events in a limited number of patients, often contemporaneous with CRS or sepsis, questioning the imputability of CAR-T cells in this heart disease. This study aims to estimate the incidence of a possible early cardiotoxicity associated with CAR-T cells. The main endpoint will be the change in cardiac function (LVEF: left ventricular ejection fraction) assessed by ultrasound between the pre CAR-T assessment and the early post CAR-T ultrasound (D3-D5).
