Researchers are studying a new treatment combination for adults with advanced breast cancer that is estrogen receptor positive, HER2 negative, and GRPR positive. The trial aims to find the recommended dose of the drug [177Lu]Lu-NeoB when given with ribociclib and fulvestrant to participants who have experienced early relapse after endocrine therapy or whose disease has progressed after endocrine therapy combined with a CDK4/6 inhibitor. This Phase 1 study includes a dose escalation part and a backfill part to assess safety, tolerability, and preliminary effectiveness. Participants will receive [177Lu]Lu-NeoB once every 28-day cycle for six cycles, ribociclib daily on days 1 to 21 of each cycle, and fulvestrant on specific days beginning at cycle 1. Pre- or perimenopausal women and men will also receive goserelin. The trial includes imaging with the radioactive agent [68Ga]Ga-NeoB at screening, possibly at cycle 2 day 15, and again 4 to 8 weeks after the last dose of [177Lu]Lu-NeoB to help locate cancer lesions. During the study, participants visit the clinic regularly for treatment, safety checks, and tumor assessments. Safety follow-up continues for 8 weeks after treatment ends, with extended monitoring every 12 to 24 weeks for up to 5 years to track side effects, adverse events, and treatment interruptions. Researchers will closely observe any dose-limiting toxicities and evaluate overall safety and effectiveness throughout the study period.

Researchers are evaluating the effectiveness and safety of Xeomin injections in preventing chronic migraine. This Phase 3 clinical trial compares Xeomin to placebo injections given into muscles of the head and neck. Participants have chronic migraine diagnosed for at least 12 months and meet specific headache and migraine day criteria. The study aims to measure changes in monthly migraine days over time with Xeomin treatment. Participants will receive four treatments spaced about 12 weeks apart over a total study duration of 52 to 55 weeks. The treatments involve injections of either Xeomin or placebo solution prepared with sodium chloride. Visits occur approximately every 4 weeks, totaling 14 visits: the first, last, and four treatment visits are on-site, while the other eight visits are remote via phone or video call. During the study, participants will keep headache diaries to track migraine and headache days. Researchers will focus on the change in monthly migraine days from baseline to six months after the first injection. Safety and effectiveness are monitored throughout, with frequent assessments during both on-site and remote visits to ensure accurate tracking of migraine symptoms and any side effects.

Researchers are evaluating the effect of Xeomin injections compared to placebo injections for preventing episodic migraine. This phase 3 clinical trial focuses on adults who experience episodic migraine, aiming to measure changes in the number of migraine days per month. Participants must have a diagnosis of episodic migraine for at least 12 months and meet specific headache frequency criteria. Participants will receive four treatments of either Xeomin or placebo injections into muscles of the head and neck, with treatments spaced about 12 weeks apart. The entire trial lasts approximately 52 to 55 weeks, beginning with a screening period of 4 to 5 weeks. There are about 14 visits in total, with the first, last, and four treatment visits conducted on-site, while the other visits are held remotely via phone or video. Throughout the study, participants will track their migraine days using a headache diary, and researchers will assess changes in monthly migraine frequency from baseline to six months after the first injection. Regular monitoring includes both in-person and remote assessments. The primary outcome focuses on the change in monthly migraine days between baseline and month six after treatment initiation.

Researchers are studying patients with metastatic colorectal cancer (mCRC) who have a specific BRAFV600E mutation. This rare subtype of mCRC has poor prognosis and resistance to current treatments, especially in tumors with microsatellite stability or proficient mismatch repair. The study aims to collect detailed clinical data and biological samples to better understand treatment outcomes, resistance, and survival in real-world settings. Participants will provide blood samples and tumor tissue samples to support various research goals. The study will evaluate circulating tumor DNA during different lines of metastatic treatment to predict treatment response and resistance. It will also analyze the immune environment of BRAFV600E mCRC tumors and study specific subgroups with mismatch repair deficiencies. Clinical management data will be collected to inform future therapeutic approaches. During the study, patients will be monitored regularly with blood sample collections of 30 mL at each time point. Researchers will gather information about treatments, survival, and biological markers over time. The main outcome measured is overall survival from diagnosis up to five years. Patients must be able to comply with study procedures and provide informed consent. The study aims to improve knowledge of this aggressive cancer subtype and support development of new treatments.

Researchers are evaluating the safety and effectiveness of combining durvalumab and domvanalimab compared to durvalumab plus placebo in adults with locally advanced (Stage III), unresectable non-small cell lung cancer (NSCLC) whose disease has not worsened after definitive platinum-based concurrent chemoradiation therapy. This Phase III, randomized, double-blind, placebo-controlled, international study involves multiple centers. Participants receive intravenous infusions of durvalumab and domvanalimab or durvalumab and placebo. The treatments are given after patients have completed concurrent platinum-based chemotherapy and radiation therapy with a total radiation dose of approximately 60 Gy. The study monitors patients over time to assess treatment effects and safety. During the study, participants undergo evaluations including tumor tissue analysis for PD-L1 status, performance status assessments, and monitoring of organ and marrow function. The main outcome measured is progression-free survival up to 8 years after randomization. Researchers also monitor for any adverse effects and disease progression throughout the study period.

Food Protein Induced Enterocolitis Syndrome (FPIES) is a non-IgE mediated food allergy that mainly appears in infancy and can cause severe vomiting, diarrhea, and dehydration. This condition is often unfamiliar to many clinicians, and its diagnosis relies on specific clinical criteria established in 2017. This study aims to collect detailed clinical information and allergy test results for children diagnosed with acute FPIES and to describe its progression and atypical forms over three years in a French population. The study will include children aged 0 to 17 years with confirmed acute FPIES, diagnosed either by the 2017 JACI clinical criteria or by oral food challenge. Allergy tests such as oral food challenges, skin prick tests, and IgE blood tests will be used to monitor patients. Participants will be seen by allergologists at the start and annually for three years. If tolerance to the offending food is not acquired, an oral food challenge will be conducted in a hospital setting to evaluate resolution. This multicenter French prospective study will gather data on FPIES evolution, including the development of IgE sensitization and clinical symptoms of IgE-mediated allergy. Throughout the study, children will undergo clinical evaluations and allergy testing at inclusion and yearly follow-up visits. Researchers will assess tolerance acquisition over an average of six years, monitor multiple FPIES cases, and record personal atopic conditions. The study will last three years for inclusion and three years of follow-up per patient, aiming to improve management of FPIES in France by understanding its unique food triggers and long-term outcomes.

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.

Researchers are evaluating the safety, tolerability, pharmacokinetics, and preliminary effectiveness of AMO959 combined with lutetium (177Lu) vipivotide tetraxetan (AAA617) and an androgen receptor pathway inhibitor (ARPI) in adult males with PSMA-positive metastatic castration resistant prostate cancer (mCRPC). The study focuses on participants who have failed one prior ARPI treatment, with or without prior taxane chemotherapy exposure. The trial is a Phase Ib/II open-label study designed to assess these treatments in this specific patient population. The study includes two phases. Phase Ib involves dose escalation of AMO959 alone and then combined with AAA617 and ARPI (either abiraterone or enzalutamide) in small groups to determine safety, tolerability, and the recommended dose for expansion. Phase II randomizes participants into three groups to receive the recommended dose(s) of AMO959 plus AAA617 and ARPI or AAA617 plus ARPI alone. Treatment administration and dose escalation meetings occur during the initial phase to monitor safety and dosing. Participants will be closely monitored for adverse events, dose-limiting toxicities, dose adjustments, and drug exposure for up to 24 to 45 months depending on the phase. Effectiveness will be assessed by measuring biochemical response through PSA levels. Eligibility involves imaging to confirm PSMA-positive disease and specific disease progression criteria. The study also tracks drug tolerability and participant safety throughout the treatment and follow-up periods.

Researchers are studying metastatic renal cell carcinoma (RCC), a type of kidney cancer that spreads to other parts of the body, affecting many patients annually in France. This study focuses on patients with oligoprogressive disease, where only a few metastatic sites (1 to 3) show progression while the rest remain controlled under ongoing systemic treatments like targeted therapies or immunotherapy. The goal is to evaluate stereotactic radiotherapy (SRT) as a focused treatment to control these progressing sites and potentially delay the need for changing systemic therapies. The study involves delivering stereotactic radiotherapy, which uses high doses of radiation in one or a few sessions to target metastatic sites specifically. Patients with up to three progressive metastases eligible for SRT will receive this treatment concurrently or sequentially alongside their current systemic therapy. This approach aims to control tumor growth locally and possibly stimulate a broader immune response. The trial is a Phase II study, assessing this treatment strategy in patients receiving first or second-line systemic therapies. Participants will undergo imaging scans to confirm disease progression and lesion sizes, with follow-up assessments to monitor progression-free survival six months after randomization. Researchers will evaluate how well the targeted radiotherapy controls tumor sites and delays further disease progression. Patients will be closely monitored for treatment effects, ability to continue systemic therapy, and overall safety throughout the study period.
