French Assessment of MRD by Liquid Biopsies in Stage III CRC Patients (FRENCH.MRD.CRC)

Improving personalized cancer treatments and finding the best strategies to treat each patient relies on using new diagnostic technologies. Currently, for colorectal cancer, the methods used to decide who gets additional post-surgery treatment are suboptimal. Some patients get too much treatment, while others do not get enough. There is a new way to explore if there is any cancer left in a patient's body using circulating tumor DNA (ctDNA) detected in blood samples. This can help decide who needs more treatment after surgery. Even though many tests have been developed, it has yet to be determined which test performs best at relevant time points. The GUIDE.MRD consortium is a group of experts, including scientists, technology, and pharmaceutical companies. The consortium is working on creating a reliable standard for the ctDNA tests, validating their clinical utility, and collecting data to help decide on the best treatment for each patient. FRENCH-MRD-CRC is the French study of the european GUIDE.MRD project.

ACetazolamide in Patients With Heart Failure, to Decrease Weight and relIEVE Symptoms.

Acute congestion is common in patients with heart failure (HF) and is associated with impaired renal function, reduced quality of life, hospital readmissions, and mortality. Current guidelines recommend optimal decongestion using diuretic therapy, mainly loop diuretics. Although acetazolamide has recently demonstrated efficacy in hospitalized patients, its role in ambulatory patients managed through remote telemonitoring remains to be established. This study aims to evaluate the efficacy of oral acetazolamide added to conventional treatment for decongesting ambulatory HF patients during congestive decompensations. ACHIEVE is a Phase III multicenter, prospective, interventional, randomized, controlled, open-label superiority trial evaluating the efficacy of oral acetazolamide added to conventional treatment for decongestion in ambulatory patients with heart failure during congestive decompensation monitored by remote telemonitoring. The primary objective is to assess, at Day 5, whether acetazolamide added to conventional treatment improves decongestion compared with standard treatment alone. Secondary objectives include evaluating efficacy, safety, and health economic outcomes, including quality of life, dyspnea, biological markers, unplanned consultations, hospitalizations, mortality, and hospital medical costs.

Developing a Comprehensive Biomarker Panel for Monitoring Progression and Early Detection in ALS Patients

Amyotrophic lateral sclerosis (ALS) is a progressive neurodegenerative disease for which reliable biomarkers for early diagnosis, prognosis, and patient stratification remain limited. Previous genetic, proteomic, imaging, and electrophysiological studies have identified potential biomarkers and phenotype modifiers, improving the understanding of motor neuron degeneration mechanisms. However, these findings have not yet been translated into a clinically useful biomarker algorithm. This observational study aims to develop a biomarker panel to support the diagnosis, prognosis, and stratification of patients with ALS. Clinical and molecular biomarkers previously associated with ALS phenotypes will be analyzed simultaneously and integrated into a multivariable predictive model. Clinical data and biological samples will be collected and analyzed to identify combinations of biomarkers associated with ALS phenotypes.

Impact of Physical Activity on Immunotherapy-induced Toxicities in Melanoma Management

Management of melanoma is based on primary excision of the tumor. In cases of melanoma with poor prognosis criteria, or when it is locally advanced or metastatic, there is an indication for the implementation of adjuvant therapy, which may, in this context, be immunotherapy. Immunotherapies are treatments that have revolutionized the prognosis of patients with melanoma. These are therapies that work by stimulating the immune system to enhance the anti-tumor response. Their toxicities are represented by immune-mediated toxicities, similar to true autoimmune diseases. Adapted physical activity as supportive care in oncology is expanding. From a pathophysiological perspective, physical activity is thought to modulate the immune system (by reducing inflammation, restoring immune surveillance, stimulating anti-tumor responses through the induction of T cell proliferation, modulating the gut microbiota, and influencing tumor microenvironment cells, etc.). The modulation of the immune system by physical activity may also allow us to hypothesize a modulation of the toxicities induced by immune checkpoint inhibitors. We wish to study this hypothesis in patients with advanced melanoma who are candidates for immunotherapy. Originality and Innovative Aspects: Physical activity as supportive care in oncology has developed significantly in recent years. However, adapted physical activity (APA) is currently only offered at one center in France (CHU de Lille). In addition to the probable impact on patients\&#39; quality of life, if we find evidence supporting a reduction in treatment-related toxicities for melanoma through physical activity, it would be even more interesting to introduce APA at the CHU of Montpellier. Primary and Secondary Objectives: Primary Objective: To analyze the association between the level of physical activity (estimated by the IPAQ questionnaire) at the initiation of immunotherapy and the occurrence of adverse effects at 6 months after starting treatment in adult patients with melanoma. Secondary Objectives: Analyze the association between physical activity level and treatment efficacy of immunotherapy in adult melanoma patients. Describe the quarterly evolution of patients\&#39; general condition through measurement of WHO status and BMI. Assess the evolution of patients\&#39; general condition: WHO status and BMI at treatment introduction, after 3 months, and at 6 months of treatment. Study the evolution of patients\&#39; quality of life during their treatment based on their physical activity level, using the QLQ-C30 questionnaire. Preliminary study: We aim to evaluate the correlation between self-reported physical activity by patients and their actual physical activity. To obtain an objective measurement of patients\&#39; physical activity level, we plan to work with the CARTIGEN platform and offer a small number of included patients (maximum of 50) to wear wrist actimeters for one week before treatment initiation. We will then analyze these data to determine patients\&#39; baseline physical activity levels and compare them with the data collected via questionnaires. This is a prospective cohort study within the context of analytical epidemiological research. It is a bicentric study: CHRU Montpellier - Saint-Eloi Hospital and ICM Val d\&#39;Aurelle. Using the collected data on patients\&#39; physical activity levels (IPAQ questionnaire), we will compare two groups: patients who experienced immuno-toxicities without physical activity versus those with moderate or high physical activity. We will also analyze treatment efficacy in these two groups, patients\&#39; quality of life, and the evolution of their general condition. Procedure: Inclusion is planned at day 0 (D0), with physical activity (IPAQ3) and quality of life (QLQ-C30) questionnaires, along with clinical and oncological evaluation. A follow-up visit at month 3 (M3) will include reassessment of clinical and oncological status, followed by another visit at month 6 (M6) for further clinical, oncological, physical activity, and quality of life reassessment. The inclusion period is expected to last 18 months. Outcomes / Perspectives: If we consider that physical exercise may help mitigate the toxic effects of treatments-an aspect we wish to explore through this project-it would be relevant to introduce adapted physical activity (APA) sessions supervised by a specialized instructor within the Dermatology Day Hospital at the CHU of Montpellier. Implementing APA in the context of onco-dermatology will strengthen the multidisciplinary approach of the CHU. Collaboration between healthcare professionals, including specialized APA instructors, will foster effective care coordination. This initiative is part of a holistic approach to patient care, integrating complementary interventions to address physical, psychological, and social needs.

Serum Neurofilaments in the Diagnosis of Amyotrophic Lateral Sclerosis

Amyotrophic lateral sclerosis (ALS) is a serious neurodegenerative disease, often difficult to diagnose due to symptoms similar to other neurological pathologies. Diagnosis can take up to 14 months, although the rapid progression of the disease requires early detection. At present, there is no validated biomarker to aid diagnosis. Serum neurofilaments light chain (NfL), markers of neuronal degeneration, show great potential to help diagnose ALS early and assess disease severity. Recent research has shown that measurement of NfL in the blood can differentiate ALS from other neurological disorders, and new technologies are increasingly making it possible to perform these tests clinically. The study hypothesis is that NfL blood levels, measured using clinical analyzers, could improve early ALS diagnosis, optimize patient recruitment for therapeutic trials and accelerate the assessment of treatment efficacy. The primary objective is to evaluate the sensitivity and specificity of serum NfL for the diagnosis and differential diagnosis of amyotrophic lateral sclerosis (ALS) in newly recruited patients referred to the ALS Reference Center at Montpellier University Hospital. The diagnosis is established according to the revised El Escorial diagnostic criteria (see Appendix). This diagnosis is determined independently of the serum NfL concentration.

Prevalence and Risk Factors for Chronic Post-Surgical Pain Following Video-Assisted Thoracic Surgery : The EVATHO Prospective Bicentric Cohort Study.

Chronic post-surgical pain (CPSP) remains a common complication after thoracic surgery and may significantly impair patients' quality of life. Although the widespread adoption of video-assisted thoracic surgery (VATS) has reduced surgical trauma and improved postoperative recovery, a substantial proportion of patients still develop persistent pain. The EVATHO study is a multicenter prospective observational cohort designed to determine the prevalence of CPSP three months after VATS and to identify perioperative factors associated with its development. Adult patients undergoing thoracic surgery by VATS at Montpellier and Nice University Hospitals will be prospectively enrolled. Pain intensity, neuropathic pain characteristics, anxiety, depression, quality of life, and analgesic consumption will be assessed using validated questionnaires during the perioperative period and at 1 and 3 months after surgery. The results of this study may help identify patients at increased risk of CPSP and improve perioperative pain management strategies following thoracic surgery.

A Prospective Randomized Non-inferiority Trial Comparing Anti-CD20 Maintenance Versus De-Escalation Strategy In Relapsing-Remitting Multiple Sclerosis

Multiple sclerosis (MS), the main central nervous system autoimmune disorder, is the first cause of non-traumatic disability in young adults and has thus significant individual consequences with elevated public health cost. It commonly starts during the third and fourth decades. Over the last twenty years, several disease-modifying therapies with variable benefit/risk profiles have been introduced leading to dramatic changes in the prognosis of MS. First, several moderately effective therapies , with good safety profile, have allowed to decrease the frequency of relapses along with a possible, albeit limited, effect on medium- and long-term disability. More recently highly effective therapies (HET), with immunosuppressive properties, have dramatically reduced clinical and MRI disease activity and significantly improved patient's prognosis. Anti-CD20 therapies (B-cells depleting therapies, given either intravenous or subcutaneous), one of the main HET, have demonstrated higher efficacy than platform therapies in several phase 3 randomized clinical trials and their use within the very first years of the disease seems to be associated with improved long-term outcomes. Taking all of this into account, the investigators hypothesize that RRMS patients who experience a de-escalation from anti-CD20 therapies to platform therapies after 40 years will not experience disease activity accrual and disability worsening.

Efficacy of Islet Re-transplantation After Failure of Beta-cell Replacement

Islet transplantation and pancreas transplantation are established therapeutic options for selected individuals with type 1 diabetes experiencing severe glycemic instability and recurrent hypoglycemia. Although these approaches significantly improve glycemic management and quality of life, long-term graft survival remains limited, with a progressive decline in beta-cell function over time. The clinical benefit-risk profile of islet re-transplantation after graft failure remains poorly defined, and outcomes following repeat islet transplantation after prior islet graft failure have not been specifically evaluated. Repeated exposure to multiple donors may increase the risk of alloimmunization, including the development of donor-specific antibodies , which may adversely affect graft survival and limit access to future transplantation. This multicenter retrospective cohort study aims to evaluate the efficacy and safety of islet re-transplantation in adults with type 1 diabetes after failure of initial beta-cell replacement (islet or pancreas transplantation), with outcomes assessed at 3 months, 1 year, and 5 years.

Conceptualizing Borderline Personality Disorder as a Relationship Use Disorder

This study aims to explore a novel conceptualization of Borderline Personality Disorder (BPD) as a "Relationship Use Disorder." The research proposes that BPD shares key features with behavioral addictions, specifically addiction to interpersonal relationships. The study builds upon previous findings suggesting that individuals with BPD experience intense emotional dysregulation, including negative self-perception, shame, and a compulsive need for external validation. This addiction to relationships, much like substance use disorders, is thought to contribute significantly to the difficulties faced by these individuals, including interpersonal conflicts, self-destructive behaviors, and emotional instability. The study seeks to demonstrate that the relational difficulties central to BPD meet the diagnostic criteria for addiction as defined by the DSM-5. It will also explore how these relational struggles are mediated by dysfunctional self-perception and whether they are linked to behaviors such as compulsive sexual behaviors (CSBD) or suicidal tendencies. Additionally, the research will investigate the relationship between addiction to relationships and neurobiological factors, including endorphin levels, in individuals with BPD compared to those with bipolar disorder and healthy controls. The hypothesis is that individuals with BPD will exhibit higher levels of relationship addiction, with this addiction being tied to their perception of self-worth and emotional experiences in relationships. This innovative approach aims to refine the understanding of BPD, reduce stigma, and improve treatment strategies by providing scientific evidence supporting the conceptualization of BPD as a "Relationship Use Disorder."

Platform for the Prospective Mother-child Study of the Determinants of Neurodevelopmental Disorders

Neurodevelopmental disorders such as attention deficit disorder with or without hyperactivity, autism spectrum disorder, language and social communication disorder, motor coordination disorder, learning disorder (dyslexia, dyscalculia, dysorthography), intellectual development disorder are frequent and long-lasting developmental difficulties that can be observed in children in various domains. They are often associated and have a significant impact on daily functioning at school and at home. The rate of people affected by neurodevelopmental disorders including autism spectrum disorder have increased significantly over the past 20 years. Improved screening only partly explains this evolution. A genetic predisposition plays an important role in the occurrence of these disorders, however, current scientific data suggest a multifactorial origin. Exposures such as those related to the use of pesticides, air pollution or the presence of endocrine disruptors in our diet could be involved in the genesis of neurodevelopmental disorders, particularly during intrauterine life, a period of great vulnerability. The current diagnostic pathways for autism rarely enable the early identification of babies at risk. Without early detection and timely targeted intervention, these children have a poor health outcome and do not reach their full potential. The general objective of the MARIANNE cohort is to constitute a French research infrastructure dedicated to research on the biological and environmental determinants of neurodevelopmental disorders including autism. This cohort is based on the follow-up of 1200 families with already a child affected by an autism spectrum disorder, which implies a high risk of neurodevelopmental disorders including autism spectrum disorder for the siblings, and of 500 families from the general population with no excess risk of neurodevelopmental disorders. The total number of subjects to be included (mother, father, unborn child and ASD sibling for the HR group) is thus 6300. The inclusion of these families will be at the beginning of a new pregnancy and the follow-up will be carried out from the second trimester of pregnancy until the children are 6 years old, the age at which the diagnosis of neurodevelopmental disorders is possible. Biological, clinical, social and environmental data will be collected at different stages of the follow-up and will be included into a large database.

Phase IIa Trial of Anti-CD19 CAR T-Cells in Systemic Sclerosis Resistant to Immunosuppressive Therapy

The goal of this clinical trial is to evaluate whether anti-CD19 CAR T-cell therapy can improve disease activity in adults with severe, treatment-resistant systemic sclerosis (SSc). The study will also assess the safety of this therapy and how CAR T-cells behave in the body. The main questions are: Does CAR T-cell therapy reduce skin thickening and other signs of SSc? What side effects occur after receiving CAR T-cells? How do CAR T-cells expand, persist, and affect B-cells and autoantibodies? Participants will: Undergo leukapheresis Receive short lymphodepleting chemotherapy Receive one infusion of anti-CD19 CAR T-cells Stay in the hospital for about 10 days Attend follow-up visits for 24 months with clinical exams, blood tests, and organ-function assessments Optional skin or lymph-node biopsies may be performed in participants who consent to these procedures. This study aims to provide early evidence on whether CAR T-cell therapy could become a promising treatment option for systemic sclerosis.

Comparing UDCA and Corticosteroids in Immunotherapy Induced Cholestatic Hepatitis

The clinical trial aims to compare the effectiveness of ursodeoxycholic acid (UDCA) to corticosteroids in treating cholestatic hepatitis induced by immune checkpoint inhibitors (ICIs) over a 21-day period. The trial presents a detailed scientific justification for comparing UDCA to corticosteroids, describing the treatment and detailing the follow-up procedures. It hypothesizes that UDCA could be superior to corticosteroids for treating ICI-related cholestatic hepatitis, based on its established use in primary biliary cholangitis and a favorable tolerance profile compared to corticosteroids.
