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.
Immunotherapy became in recent years a major innovation in the care of cancer patients, with unprecedented improvement in complete response and survival, particularly in hematological cancers. Since 2018, patients with relapsed or refractory lymphoma can benefit from immunotherapy based on CAR-T cells (Chimeric Antigenic Receptor - T cells), drugs derived from gene therapy and products from the patient's own T cells. The efficacy of these drugs, their development in more and more indications and in continuous earlier lines of treatment, their unprecedented adverse effects and their very high cost justify the search for predictive factors of efficacy and tolerance in order to optimize their use and benefit the greatest number of eligible patients. A better understanding of quality of life and its determinants in patients who received CAR-T cells could play a major role in predicting efficacy and tolerance. Quality of life data have indeed been deemed insufficient in phase 1-2 trials which have demonstrated the benefit of CAR-T cells in patients with relapsed or refractory diffuse large B-cell lymphoma (DLBCL) in 3rd line of treatment or more and led to obtaining their marketing authorization. It is therefore necessary to assess the quality of life of patients treated in routine care with CAR-T cells. The European Qualitop project aims, from self-questionnaires, to explore the quality of life during the 2 years following the initiation of immunotherapy with a multidimensional approach integrating genetic factors, lifestyle habits and psychosocial determinants of patients. In this context, the Qualitop CAR-T study is a prospective non-comparative real-life study aimed at describing the multidimensional quality of life, its psychosocial determinants and drug consumption in patients with relapsed or refractory DLBCL treated with CAR -T cells.
Hidradenitis Suppurativa is a recurrent chronic inflammatory follicular occlusive disease affecting hair follicles. HS is notoriously difficult and challenging to treat with a high morbidity impact and could be classified as an unmet medical need with no efficient therapeutic options. Objective: Investigators previously showed that Outer Root Sheath Cells (ORS) isolated from hair follicle of HS patients (HS-ORS) have a pro-inflammatory phenotype and secrete spontaneously IP-10 and RANTES. To identify the mechanisms involved in the pro-inflammatory phenotype of HS-ORS, investigators performed a transcriptomic analysis in healthy and HS patients. This revealed: (i) an IFN signature, (i) a dysregulation of genes involved in cell proliferation and differentiation, and (iii) an upregulation of DNA damage response and cell cycle G2/M checkpoint pathways in HS-ORS. These findings support the notion that, in HS patients, a perturbation of HF-SC homeostasis leading to an increased proliferation induces a replicative stress and an accumulation of cytoplasmic ssDNA, stimulating IFN synthesis through IFI16-STING pathway. Interestingly, replicative stress in ORS were present in some but not all patients with Hidradenitis Suppurativa. The goal of study is to determine replicative stress in ORS in a large cohort of HS patients. Method Patients will be enrolled in the Mondor Dermatology department, during routine care. A dermatologist will check all inclusion and exclusion criteria with the technical support of a research technician of the Henri Mondor Clinical Investigation Center. Medical history, clinical data, comorbidities and concomitant therapies will be prospectively recorded in a dedicated case report form. Skin biopsies will be performed in perilesional zone rich in hair follicles. mRNA will be extracted from freshly isolated hair follicle cells and some slides will be prepared and stored at -80°C to perform immunohistochemistry analysis on freshly isolated hair follicle cells. PBMC and serum will be collected. All these biological samples will allow us to quantify the replicative stress in HS-ORS of each patient, and to quantify several cytokine of interest : IFN de type 1, IL-17, IL-6, TNF-α, IL-10 This study will allow investigators to evaluate the rate of patients with replicative stress in hair follicle stem cells in Hidradenitis Suppurativa. The investigator will also determine whether HF-SC replication stress correlates with clinical characteristics and/or with clinical course and/or comorbidities.
The overall objective of this study is to better understand the relationship between the body and its environment, including cognitive performance, following repeated changes in gravity, including microgravity (0G) and modified gravity (i.e., hypergravity (1.8G) and modified gravity (Martian gravity)
The metastatic colo-rectal cancer (especially with hepatic metastatic lesions, but also peritoneal or pulmonary lesions) is a major public health issue, because of its frequency, the heavy treatments and the cost of new therapeutic molecules involved, in particular targeted therapies that can result in specific adverse events. The first-line treatment often consists of a polychemotherapy, which can be associated to a targeted therapy. According to the therapeutic response, patient condition and disease extent, some patients may benefit from prognosis-changing treatments such as surgery of metastases. However, the best morphological response is most of time evidenced after only 6 or 8 cycles of treatment, corresponding to 3 to 4 months. Therapeutic evaluation with FDG PET/CT is validated in several neoplasia (lymphoma, breast cancer). Data on FDG PET evaluation of colic cancer chemotherapy are currently insufficient to propose its use in the usual clinical setting. We thus are going to study the performance of early FDG PET therapeutic evaluation to predict response to first-line chemotherapy in patients with potentially resectable metastases. If early PET diagnostic performances prove satisfying, this approach could become of paramount importance to tailor therapeutic strategy for these patients, with the possibility of early modification of chemotherapy protocol, which is now possible thanks to the existence of therapeutic alternatives (chemotherapy intensification, replacement of oxaliptaine by irinotecan or conversely, replacement of an anti-EGFR by an anti-angiogenic or conversely).
The main objective of RIGHT-CRT is to assess the impact/efficacy of CRT on functional capacity in ACHD patients with SRV.
There is a risk of falls and injuries in bedridden hospitalized patients, increased in agitated or confused patients. In neurosurgery departments, brain damaged patients can present a loss of consciousness of risky behaviors and be in a state of agitation which frequently leads to their endangerment. The repercussions of this endangerment are multiple. For the patients, there may be a feeling of insecurity, with physical or chemical restraint solutions which deprive them of their freedom without a total guarantee of safety. For the caregivers, there is an emotional distress in front of this endangerment, and a professional guilt. Finally, there are economic repercussions due to the costs of complementary examinations and the lengthening of hospitalization. The objective of the present study is to determine the nature and frequency of occurrence of risk behaviours, through the observation of bedridden and agitated hospitalized patients. These risk behaviours are defined as potentially dangerous and are warning signs for the caregiver. A better understanding of these behaviours could help to better anticipate falls and injuries and to implement preventive measures more quickly.

Mutations in the genes encoding cytosolic aminoacyl-tRNA synthetases are responsible for early-onset multisystemic diseases including to varying degrees interstitial lung disease, liver damage, neurological and digestive disorders, and systemic inflammation. These are rare and severe diseases whose pathophysiology is poorly understood. The investigative team hypothesizes that mutations within these genes are responsible for a decrease in protein translation and lead to a cellular stress response similar to that induced by amino acid deprivation. The investigative team also hypothesizes that these alterations could be corrected by high-dose supplementation in the culture medium of the corresponding amino acid. The main objective of the study is to precisely determine the consequences of cytosolic aminoacyl-tRNA synthetase mutations at the cell level on protein translation.
Delayed graft function occurs in more than 20% of kidney transplantations. It is an episode of post-ischemic acute kidney injury with long-term consequences on the allograft's function. Based on preclinical data and on a stage 1 clinical trial, the hypothesize is that an acquired defect in NAD+ biosynthesis is instrumental in delayed graft function and that a treatment with high doses of vitamin B3 (nicotinamide) will improve the early renal graft function. Thus, it is planned to recruit 204 kidney allograft recipients immediately before transplantation and randomize them to either placebo or nicotinamide treatment for 3 administrations before transplantation, immediately after it and on the next day. The efficacy of nicotinamide to foster early graft function will be evaluated by comparing the creatinine reduction ratio between the placebo and the nicotinamide treated groups. Serum will be collected before and 2 days after transplantation and urine 2 days and 3 months after transplantation to study the relationship between biological markers of NAD+ biosynthesis and nicotinamide's effect on early kidney graft function.
