Researchers are evaluating the safety and effectiveness of the VCFix Spinal System for treating Vertebral Compression Fractures. The study aims to reduce pain related to vertebral fractures and improve physical function and mobility, while ensuring no serious adverse events related to the device or procedure occur. This clinical investigation focuses on a device designed to realign and stabilize fractured vertebrae with potential benefits over traditional bone cement methods. The VCFix Spinal System is a device that can be adjusted in place to restore vertebral height and correct spinal alignment. It features a titanium structure that supports natural bone healing and may provide better stability without the use of bone cement. The device also connects the front and back parts of the spine to improve load distribution and support more severe fractures. Participants receive this device in a stand-alone configuration as part of the treatment. Participants will be monitored for changes in pain intensity using an 11-point pain scale and physical function using the Oswestry Disability Index over 6 months. Safety is closely observed, particularly for serious adverse device effects within the first month after treatment. The study includes assessments of pain, function, and adverse events to evaluate the overall impact of the VCFix system. The study involves adults aged 21 to 85 with specific types of vertebral fractures suitable for this treatment.

Researchers are studying whether combining calderasib, a targeted therapy for the KRAS G12C mutation, with subcutaneous pembrolizumab can treat non-small cell lung cancer (NSCLC). The study aims to determine if people receiving calderasib with pembrolizumab live longer without their cancer growing or spreading compared to those receiving pembrolizumab with chemotherapy. This is a phase 3, randomized, open-label, multicenter clinical trial focusing on participants with advanced or metastatic nonsquamous NSCLC carrying the KRAS G12C mutation. Participants will receive one of two treatment combinations. One group will take calderasib orally along with subcutaneous pembrolizumab and berahyaluronidase alfa injections. The other group will receive subcutaneous pembrolizumab combined with chemotherapy drugs pemetrexed and a platinum-based drug, either carboplatin or cisplatin, administered by intravenous infusion. These treatments are given as first-line therapy, and the study evaluates their safety and effectiveness. During the study, researchers will monitor participants for progression-free survival, especially focusing on those with at least 1% PD-L1 tumor proportion score, for up to approximately 48 months. Participants will undergo regular assessments to track cancer progression and response to treatment. Safety and efficacy data will be collected throughout the study to understand how well the treatments work and their side effects over time.

Researchers are evaluating the efficacy and safety of rilvegostomig compared to pembrolizumab as first-line treatments for patients with metastatic non-small cell lung cancer (mNSCLC) whose tumors have high PD-L1 expression. This Phase III, randomized, double-blind, and global study focuses on participants with stage IV mNSCLC who do not have certain genetic mutations or rearrangements and are eligible for systemic therapy. Participants receive either rilvegostomig or pembrolizumab intravenously on Day 1 of each 21-day cycle. The study compares these two biological treatments given as monotherapy. Both groups will be monitored over time to assess treatment impact and safety. Throughout the study, participants undergo evaluations including tumor measurements by CT or MRI, performance status assessments, and organ function tests. Researchers will measure overall survival and progression-free survival for up to approximately five years. Tumor samples are collected before treatment for central testing, and participants’ health and treatment responses are closely followed during the trial period.

Researchers are creating a national, prospective cohort to study children with idiopathic nephrotic syndrome (INS), a rare kidney disease. The goal is to collect detailed data on patients treated in pediatric nephrology centers across France, Reunion Island, Mayotte, and eventually other French overseas territories. This structured follow-up aims to better understand the disease's characteristics and provide a foundation for future clinical trials. The study involves enrolling pediatric patients diagnosed with INS and systematically collecting clinical, biological, psychological, and social data. Biological samples such as blood, urine, hair, and nails will be gathered at disease onset before immunosuppressive treatment begins. Data will be recorded through medical records from hospital visits and consultations, supplemented by annual telephone interviews for patients without active disease. Quality of life, treatment adherence, and aesthetic impact questionnaires will also be collected and integrated into a secure database. Participants will be followed over at least two years, with data collected regularly by clinical research staff. This includes medical validation of clinical information, annual telephone follow-ups, and questionnaire assessments. The study's primary outcome is the number and characteristics of included cases over two years. This ongoing monitoring will support future nested studies and improve understanding of pediatric INS outcomes and management.

Malignant hypertension is a very severe type of high blood pressure that can be fatal if not treated. It mainly affects younger adults aged 35 to 55 and carries a high risk of serious heart and kidney problems. Despite its severity and increasing cases, research on malignant hypertension is limited, with diagnostic criteria and treatment guidelines that have not changed since 1929. This study aims to create the first prospective, multicenter registry to better understand the disease's epidemiology, care practices, and biological aspects, and to modernize its definition and diagnosis. The study plans to enroll 500 patients diagnosed with malignant hypertension based on classic criteria, including severe high blood pressure above 180/110 mmHg and evidence of organ damage. It will collect detailed data on patient characteristics, affected organs, and treatment approaches used in various centers. This registry will help develop new diagnostic and treatment recommendations based on solid scientific evidence and may lead to future therapeutic trials. Participants will be followed to evaluate their health outcomes over five years, focusing on their cardiovascular and renal prognosis. Researchers will analyze how patient profiles and the number and type of organ damage affect their long-term outlook. The study will document epidemiology, care pathways, organ involvement, and management strategies in detail to improve understanding and care of malignant hypertension.

Chronic lymphocytic leukemia (CLL) is the most common type of leukemia affecting blood cells. This research aims to evaluate the safety of the drug venetoclax when combined with either obinutuzumab or acalabrutinib for treating adults with previously untreated CLL. The study focuses on monitoring side effects and changes in disease activity to better understand treatment risks, including the risk of tumor lysis syndrome (TLS). Participants will be assigned to one of four treatment groups. All will receive oral venetoclax with different ramp-up schedules combined with either intravenous obinutuzumab or oral acalabrutinib. Treatment arms vary in their dosing schedules and combination therapies. The total study period lasts about 28 months, during which participants receive their assigned treatments and monitoring. Throughout the study, participants will have regular visits at hospitals or clinics for medical exams, blood tests, and side effect checks. Questionnaires will also be completed to assess their condition. Researchers will track the occurrence of TLS and other laboratory indicators related to safety. This ongoing monitoring will help understand treatment effects and ensure participant safety over the study duration.

Researchers are studying an experimental drug called odronextamab in combination with lenalidomide for adults with relapsed or refractory follicular lymphoma (FL) or marginal zone lymphoma (MZL), which are subtypes of Non-Hodgkin's lymphoma. This Phase 3 study has two parts: Part 1 focuses on the safety and tolerability of this drug combination and determining the appropriate odronextamab dose, while Part 2 compares the effectiveness of this combination to the current standard treatment of rituximab plus lenalidomide. The study also explores side effects, drug levels in the blood, antibody development against the study drug, and impacts on quality of life and daily activities. Participants receive either odronextamab plus lenalidomide or rituximab plus lenalidomide according to the study protocol. Part 1 is not randomized, focusing on safety and dose finding, while Part 2 is randomized and controlled to assess efficacy and safety. Treatments are administered per protocol guidelines during these study phases. During the study, participants undergo regular evaluations including imaging scans to measure disease, blood tests, and monitoring for side effects up to two years. The main outcomes measured include dose-limiting toxicities within 35 days, treatment-emergent adverse events over two years, and progression-free survival over five years. Participants are also monitored for quality of life and ability to perform daily activities throughout the trial duration.

Researchers are conducting a Phase III, international, multicenter, randomized, double-blind, placebo-controlled trial to evaluate the safety and effectiveness of androgen deprivation therapy (ADT) with or without darolutamide in men with newly diagnosed metastatic prostate cancer who have vulnerable functional ability. These patients have not chosen treatment with docetaxel or other androgen receptor pathway inhibitors. The study plans to enroll 300 participants who meet specific frailty and disease criteria. Participants will be randomly assigned to one of two groups: the experimental group will receive ADT plus darolutamide 600 mg taken orally twice daily, and the control group will receive ADT plus a placebo taken orally twice daily. Treatment will continue until there is evidence of disease progression on radiographic scans or if the patient or investigator decides to stop treatment for reasons such as side effects or other health conditions. After stopping treatment, patients will enter a follow-up phase lasting up to 10 years to monitor survival, additional cancer treatments, and any ongoing or new side effects. During the study, patients will undergo assessments according to established prostate cancer clinical trial criteria to evaluate their response to treatment. Researchers will monitor the time until disease progression or death for up to 18 months as the main outcome. Safety and treatment effects will be tracked through scheduled visits, laboratory tests, and imaging. The long-term follow-up will help understand survival outcomes and the impact of subsequent treatments over many years.

Researchers are studying the biological features of advanced ALK-rearranged non-small cell lung cancer (NSCLC) in patients treated with new generation tyrosine kinase inhibitors (TKIs) as their first therapy. This study is part of the national EXPLORE ALK cohort, a multi-center observational project in France, focusing on patients with this specific genetic alteration. The goal is to better understand the tumor biology and resistance mechanisms by analyzing samples from diagnosis through disease progression. The study collects tumor tissue samples at diagnosis and, when possible, at disease progression for RNA sequencing to identify ALK fusion partners, variants, and co-mutations. Blood samples are also taken at diagnosis, first tumor evaluation, and at progression to analyze circulating tumor DNA (ctDNA) using next-generation sequencing panels that detect mutations, fusions, and other genetic changes. These biological analyses are centralized at specialized centers such as the Léon Bérard Center and Rouen University Hospital. Patients are treated with approved ALK inhibitors like alectinib, brigatinib, lorlatinib, or entrectinib as part of their standard care. Participants will provide blood samples at multiple time points and, if possible, tumor biopsy samples for detailed genetic analysis. Researchers will monitor the progression-free survival from treatment start for up to 72 months. The study involves regular evaluations to assess tumor status and collect biological material to track genetic changes over time. Consent for sample collection and participation in the study is required, and patient data is managed within the national health system framework.

Researchers are evaluating the effectiveness of different antimicrobial treatments for infections caused by difficult-to-treat Pseudomonas aeruginosa bacteria. This infection is especially challenging for patients who are critically ill or have weakened immune systems. The study focuses on comparing new beta-lactam/beta-lactamase inhibitor combinations, cefiderocol, and older drugs like aminoglycosides and colistin in real-life clinical settings across multiple hospital centers in France. Participants will receive intravenous antimicrobial therapy tailored to treat their difficult-to-treat P. aeruginosa infection. The study observes the use of new and older antimicrobial drugs to assess their clinical efficacy. Patient data and bacterial samples will be collected and analyzed centrally to better understand drug resistance mechanisms and treatment outcomes. Participants will be monitored for clinical cure shortly after completing therapy and on Day 7 ± 2 days. Researchers will collect clinical information through electronic case-report forms and send bacterial isolates to a national center for detailed testing. Outcomes include cure rates, resistance development, adverse events, and mortality rates, with follow-up during hospitalization and up to 28 days after treatment. The study aims to provide valuable real-world data on treating these challenging infections.
