The LuDO-N Trial is a phase II multi-center clinical study investigating the use of 177Lu-DOTATATE in children with recurrent or relapsed high-risk neuroblastoma. This trial aims to assess how well this treatment works by measuring the response at 1 and 4 months after treatment ends. Secondary goals include evaluating survival rates, treatment-related side effects, and examining how tumor characteristics relate to treatment response. Participants receive two doses of 177Lu-DOTATATE administered intravenously, with at least two weeks between doses. The first dose is based on the patients weight, while the second dose is adjusted using scans to control radiation exposure, particularly to avoid kidney toxicity. Patients must be prepared for autologous stem cell transplantation as part of this intensified treatment approach. During the study, participants will undergo various scans and laboratory tests before starting treatment and at scheduled times to monitor tumor response and side effects. Researchers will assess treatment effectiveness using established neuroblastoma response criteria and will follow patients for up to five years to monitor survival and any long-term effects. The total participation time includes treatment administration and extended follow-up for safety and outcomes.

Researchers are evaluating CPV-104, a new medicine designed to regulate the complement system, which can be overactive in diseases such as C3 glomerulopathy C3G, a very rare kidney disorder. This phase 1 trial is the first time CPV-104 is being tested in people, including both healthy adults and adults with C3G, to assess its safety, tolerability, how the body processes the medicine, and whether the immune system reacts to it. The study has two parts Part 1 involves healthy volunteers receiving a single intravenous dose of CPV-104 or a placebo in a randomized, double-blind manner across several dose levels. Part 2 includes patients with C3G receiving four weekly intravenous doses of CPV-104 without placebo. Doses are escalated if the medicine is tolerated, and a Safety Review Committee regularly reviews results to ensure safety before progressing. Participants will undergo close monitoring throughout the study, including side-effect checks, blood and urine tests, ECGs, vital signs, and blood samples to measure drug levels and antibodies. For C3G patients, kidney function will also be observed. The primary outcome is the incidence of severe and serious adverse drug reactions up to Day 29 for healthy volunteers and Day 50 for C3G patients. The total study duration varies by part, with detailed safety assessments conducted throughout.

Researchers are evaluating different arthroscopic meniscus repair methods for young patients with traumatic meniscal tears. This study compares the outcomes of a standard meniscus suturing technique with a technique that includes an additional fibrin clot approach, aiming to understand how these tools affect meniscus recovery after repair. The trial involves patients under 19 years old with traumatic isolated full-thickness meniscal tears. The study randomly assigns participants into two groups one undergoes the conventional arthroscopic meniscus repair, and the other receives meniscus repair with fibrin clot augmentation. The fibrin clot is prepared from the patients blood and placed carefully into the meniscus during surgery to potentially enhance healing. Both groups are monitored over a long term to compare their recovery. Participants are assessed before treatment and then at 12 and 24 months after surgery using knee function questionnaires like the Pediatric International Documentation Committee Subjective Knee Form, Lysholm knee scale, and pediatric quality of life surveys. Clinical evaluations focus on pain, swelling, knee motion, and MRI imaging to track healing. Revision surgery rates are also recorded to measure treatment success during follow-up.

This research aims to evaluate elafibranor, a study drug, compared to a placebo in adults with Primary Biliary Cholangitis PBC and cirrhosis, a liver disease causing bile duct damage and scarring. The trial focuses on whether elafibranor can better prevent worsening of the disease, including progression leading to liver transplant or death, and also assesses long-term safety and symptom impact such as itching and tiredness. Participants will be randomly assigned to take either an 80 mg tablet of elafibranor or a matching placebo tablet once daily, orally, with or without food. This double-blind treatment period can last up to 3.5 years for each participant, with tablets taken at approximately the same time each morning. The study is designed to compare these two groups over the long term. During the study, participants will undergo regular assessments including physical exams, vital signs, electrocardiograms, laboratory tests, and symptom questionnaires at intervals up to 3.5 years. Researchers will measure liver function tests, symptom scales, liver stiffness, and clinical outcomes related to disease progression. Safety is monitored through adverse event tracking and laboratory parameters, with follow-up extending to four weeks after the last dose. Overall participation may last up to 3.5 years.

Researchers are evaluating a mentalization-based prevention program aimed at improving well-being and mental health in children aged 8 to 10 years and their families across four European countries Germany, Lithuania, Spain, and Switzerland. The study is designed as a partially randomized controlled trial and investigates how multi-level interventions involving children, parents, and teachers can promote mental health, reduce stigma, enhance help-seeking behavior, and improve classroom climate and parenting skills. The program includes a universal prevention workshop delivered at schools for all children, focusing on mental health awareness and peer support skills. Parents receive one of two different intervention trainings or a parenting guidebook one group attends 10 weekly sessions of the Lighthouse Program targeting secure attachment and reflective parenting behaviors, and another group participates in 6 bi-weekly Mentalization Based Skills Training sessions focusing on attentional control and emotion regulation. An active control group receives a parenting guidebook, while a passive control group participates in follow-up assessments without intervention. Participants will be involved in data collection at multiple time points baseline, post-intervention at 3 months, and follow-ups at 6 and 12 months. Assessments include questionnaires measuring childrens and parents well-being and mental health, parental efficacy and stress, classroom climate, teaching efficacy, and mental health stigma. Focus groups after the post-assessment will gather feedback on implementation and satisfaction. The study aims to follow 5,000 children, their parents, and teachers over a year to evaluate long-term program effects.
