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.
Virtual reality has been shown to reduce the pain experienced during medical procedures. The aim of this study is to determine to what extent the use of this technique could make it possible to defer the administration of neuroleptanalgesia during the endovenous thermal treatment of superficial varicose veins in addition to local anaesthesia by tumescence.
Primary hyperoxaluria type 1 (PH1) is a rare genetic disease caused by mutation in the AGXT gene encoding the hepatic peroxisomal enzyme AGT. Reduced AGT activity results in increased glyoxylate and oxalate production, causing the formation of kidney stones, nephrocalcinosis and renal failure. Clinical trials of Lumasiran have provided information on the efficacy and safety of Lumasiran in the treatment of primary hyperoxaluria type 1. However, they do not provide data on long-term efficacy, safety and patient management. As part of the post-marketing follow-up of Lumasiran, in agreement with the authorities, this study proposes a retrospective and prospective follow-up over 5 years of pediatrics and adults patients treated in France with a standardized clinical, biological and radiological follow-up. The main objective is to monitor the evolution of PH1 parameters and particularly oxaluria before and after treatment.
The preoperative evaluation of bladder tumors includes either computed tomography, magnetic resonance imaging in B-mode, or a cystoscopy in the absence of a radiological diagnosis. The diagnosis is confirmed after a transurethral resection of the bladder (TURB) and a histopathological analysis. Ultrasound is a non-invasive imaging technique that uses high-frequency sound waves to produce images of internal structures. Conventional ultrasound in B-mode can only provide details about the tumor's number, size, and location. Elastography uses ultrasound imaging techniques to examine the stiffness of a tissue. Using the Aixplorer system many recently published papers suggested that ShearWave Elasticity (SWE) imaging, enables the differentiation of low- from high-grade breast tumors by assessing the elasticity of the tissue. Investigators intend to evaluate the stiffness of bladder tumors with ultrasound elastography in comparison with cystometry parameters and tumoral grade.
Acute myeloid leukemia (AML) is a malignancy of aging endowed with poor prognosis. The combination of the hypomethylating agent azacitidine (AZA) with the BCL-2 inhibitor venetoclax (VEN) is the first-line treatment of older AML patients but is endowed with substantial resistance. The project leverages functional precision oncology, single-cell studies and mouse experiments to dissect the mechanisms of primary and adaptive resistance to AZA/VEN. The primary objective is to prospectively validate an ex vivo drug sensitivity testing (DST) assay as predictor of primary resistance to first-line AZA/VEN in 100 unfit AML patients. The study will also explore whether newer DST assays with enhanced niche mimicry can improve on the standard assay. By serially interrogating the short-term fate of both leukemic and immune cells upon AZA/VEN exposure in patients primed towards refractoriness, transient or prolonged remission, the aim is to dissect the cell-intrinsic and immune-mediated mechanisms of primary versus adaptive resistance. A parallel flow cytometry study will interrogate the role of senescence in AZA/VEN activity. These translational studies will be mirrored by experiments in a transplantable AML model derived from syngeneic mice harboring the age-related Tet2-/- leukemia-predisposing genotype. Lineage tracing single-cell experiments will backtrack AZA/VEN resistance to determine whether it is driven by selection or adaptation. The actionable stress sensor Pml will be invalidated in the same model to determine whether Pml-driven senescence contributes to AZA/VEN anti-leukemic activity in vivo. The project will pave the way to the clinical implementation of functional precision oncology in a high-risk malignancy. By simultaneously interrogating cell-intrinsic and immune-mediated drug resistance in vivo in a prospective patient cohort mirrored by controlled mice experiments, the project will provide a framework for the integrative analysis of drug resistance in cancers.
The aim of this study is to evaluate the impact of discharge from hospital with a weight of less than 2 kilos. To do this, the investigator will look at the short-term and long-term outcome of newborns weighing less than 2 kilos who were discharged from the neonatology department at the NOVO hospital between 2012 and 2023.
This is a parallel group, Phase 3, multinational, multicenter, randomized, double-blind, placebo controlled, 3-arm study for treatment of participants diagnosed with moderate-to-severe atopic dermatitis (AD) with a history of inadequate response of topical treatment, on background topical corticosteroid (TCS) and/or topical calcineurin inhibitor (TCI). The purpose of this study is to measure the efficacy and safety of treatment with amlitelimab solution for subcutaneous (SC) injection compared with placebo in participants with moderate to severe AD aged 12 years and older on background TCS and/or TCI. Study details include: At the end of the treatment period, participants will have an option to enter a separate study: the blinded extension study EFC17600 (ESTUARY). For participants not entering the blinded extension Study EFC17600 (ESTUARY), the study duration will be up to 44 weeks including a 2 to 4-week screening, a 24-week randomized double-blind period, and a 16-week safety follow-up. For participants entering the blinded extension Study EFC17600 (ESTUARY), the study duration will be up to 28 weeks including a 2 to 4-week screening and a 24-week randomized double-blind period. The total treatment duration will be up to 24 weeks. The total number of visits will be up to 10 visits (or 9 visits for those entering the blinded extension study EFC17600 (ESTUARY).
The objective of the VIRCHILLD project is to identify age-related modifications of the bronchial epithelium physiology that account for differences in the response and susceptibility to respiratory viruses. Epidemiology and cell-based data show that respiratory virus infections differentially affect children, adults or the elderly populations. The current worldwide pandemic of SARS-CoV-2 clearly highlighted this notion with a large part of the deaths occurring in the elderly population and very few deaths amongst children. This may be linked to a decreased transmission and/or viral load with SARS-CoV-2 in children compared to adults and elderly. Less in the public eye is the observation that other major respiratory virus targeting the bronchial epithelium (BE) such as rhinovirus (RV) and adenovirus (AdV) cause important clinical feature in children and have a much lower incidence in adults and the elderly populations, which is the opposite to the situation with SARS-CoV-2. Based on this remarkable discrepancy between respiratory viruses the investigators hypothesize that intrinsic age-controlled properties of the respiratory epithelium under resting physiological conditions determine virus susceptibility and virus propagation.

Facioscapulohumeral muscular dystrophy (FSHD) is characterized by clinical diversity, with FSHD1 being the most common form. It is associated with a toxic gain of function of the Double homeobox 4 (DUX4) gene, leading to muscle cell death and weakness. Despite the lack of approved treatments, recent studies highlight inflammation's role in early FSHD progression, triggered by inappropriate DUX4 expression. In understanding inflammation's pivotal role in FSHD, a study assessed serum cytokines in 100 adult FSHD1 patients. Out of the 20 cytokines examined, 10 showed significantly altered expression levels compared to healthy controls of similar age and sex. FSHD1 patients exhibited heightened levels of inflammatory cytokines and diminished anti-inflammatory cytokines, signaling chronic inflammation. Notably, Interleukin-6 (IL-6) emerged as a promising disease activity biomarker, displaying robust correlations with established clinical severity and functional scores. Given the pathological significance of inflammation and the correlation of IL-6 levels with disease severity, the ReInForce study will explore the satralizumab, an IL6-receptor (IL6-R) antagonist, for its efficacy in specifically reducing muscle and systemic inflammation. By antagonizing IL-6R downstream signaling, satralizumab holds promise in mitigating inflammation and potentially curtailing fibrofatty degeneration in FSHD.
France has one million people with heart failure (HF). Exercise intolerance, characterised by dyspnoea, is the main clinical symptom in HF patients and a key determinant of reduced quality of life. In addition to drug and surgical treatments, cardiac rehabilitation programmes have shown benefits in heart failure patients. Lasting at least 3 weeks, these programmes improve physical abilities, quality of life and reduce the risk of hospitalisation for heart failure patients. To date, the real challenge is no longer to prove the benefits of cardiac rehabilitation, but to find solutions to maintain its long-term effects. The transition between the end of the supervised programmes in the centre and the return home is a difficult phase for the majority of patients who do not continue regular physical activity and thus quickly lose the benefits of the programme. To help maintain the benefits of cardiac rehabilitation, some centres offer patients programmes to continue physical activity during phase III. Although these options are often beneficial in the first few months after the end of rehabilitation compared to control groups, the long-term results are mixed. These results imply that one of these maintenance options may not be suitable for all patients. It is therefore important to propose a personalised post-rehabilitation follow-up involving the patient in the choice of physical activities to optimise the maintenance of long-term benefits. We hypothesise that patients who receive personalised support from a sport and health professional following rehabilitation maintain long-term benefits compared to a control group who do not receive this support.
