Researchers are conducting a Phase 3 pediatric study to create a framework for evaluating the safety and effectiveness of drugs for managing obesity or overweight conditions in children and teens. The study focuses on participants who have struggled to lose weight despite structured diet and exercise programs. The goal is to assess treatments for long-term weight management in this young population. Participants will receive either the study drug Orforglipron or a placebo orally. The interventions will be detailed in specific substudies, called ISAs, which may start independently as new treatments become available. Results from all ISAs will be reported once all are completed, providing insights into the treatments effects on pediatric obesity or overweight. During the study, participants will be evaluated from baseline to week 72, with the primary outcome measuring the number of participants assigned to each ISA. Participants will undergo assessments including body mass index evaluations based on age- and gender-specific growth charts, and monitoring for weight-related health conditions. Safety and efficacy data will be collected throughout the study duration, which extends to March 2027.

Researchers are evaluating the long-term safety and effectiveness of the FDA-approved VARIPULSE catheter system for pulmonary vein isolation PVI in adults with symptomatic paroxysmal atrial fibrillation PAF. This device-based study focuses on participants who have not responded well or cannot tolerate at least one Class I or III antiarrhythmic drug and are candidates for catheter ablation. The goal is to monitor the outcomes of using this specific catheter system in managing PAF. Participants will undergo electrophysiology mapping and pulsed field ablation PFA using the VARIPULSE catheter combined with the TRUPULSE generator to perform pulmonary vein ablation. The study is a single-group design where all participants receive this intervention to treat their symptomatic PAF. The ablation procedure is followed by a long-term observation period to assess safety and effectiveness. During the study, participants will be closely monitored for early adverse events within 7 days after the ablation procedure and for freedom from documented atrial tachyarrhythmia episodes from day 61 up to 1095 days post-procedure. Assessments include follow-up testing and compliance with study requirements over this extended period to evaluate both short-term and long-term outcomes. The total study duration extends through 2030, with ongoing safety and effectiveness evaluations.

Researchers are evaluating disitamab vedotin alone or combined with pembrolizumab to treat urothelial cancer that expresses HER2. This study focuses on participants with locally advanced or metastatic urothelial cancer that cannot be removed by surgery. It aims to assess how well the drug works and to monitor the side effects experienced by participants. Participants receive disitamab vedotin intravenously every 2 weeks, either alone or with pembrolizumab given by intravenous infusion on Day 1 of each 6-week cycle. The study includes multiple cohorts receiving different combinations or monotherapy treatments. The treatment period and monitoring last approximately 2 years, with ongoing assessments of drug effects and safety. During the study, participants undergo regular evaluations including imaging scans to measure tumor response, laboratory tests, electrocardiograms to monitor heart function, and assessments of side effects. Researchers measure treatment response using established cancer evaluation criteria and track survival and disease control over about 3 years. Participants are closely monitored for adverse effects and blood levels of the drugs to understand how the treatments behave in the body.

Researchers are evaluating the effects of orforglipron, taken once daily by mouth, compared to placebo in adolescents aged 12 to 17 years who have obesity or are overweight with related health conditions. The study aims to assess the drugs efficacy, safety, and how it is processed by the body. This phase 3 trial is conducted under a master protocol and sponsored by Eli Lilly and Company. Participants will be randomly assigned to receive either orforglipron or a placebo orally once daily. Those who complete the initial PW01 study, including a safety follow-up period, may continue receiving orforglipron for an additional 156 weeks while maintaining lifestyle interventions such as diet and exercise counseling. The trial follows a double-blind design where neither participants nor researchers know the assigned treatment. During the roughly 18-month participation, adolescents will undergo regular assessments including body mass index BMI, body weight, waist circumference, blood pressure, cholesterol, glucose levels, insulin levels, body fat mass via DXA scans, and quality of life related to weight impact. Pharmacokinetic measurements will also be taken to study the drugs concentration over time. Safety and effectiveness will be monitored through these evaluations at baseline and at Week 72.

Researchers are evaluating the safety and performance of the Indigo Aspiration System in patients with lower extremity acute limb ischemia LE ALI, a condition involving sudden blockage of blood flow in the lower limbs. The study aims to collect clinical evidence to support the use of this device in removing blood clots causing the ischemia. This observational study focuses on patients diagnosed with LE ALI and assesses the devices impact on limb salvage and other clinical outcomes. Participants will undergo treatment using the Indigo Aspiration System, which involves mechanical aspiration thrombectomy to remove the thrombus. The study includes patients with confirmed arterial occlusion in the lower limb, using the device as the first-line treatment. The intervention is delivered with computer-assisted vacuum thrombectomy aspiration tubing during the procedure. During the study, participants will be monitored for outcomes such as target limb salvage rate at 30 days post-procedure, technical success immediately after the procedure, and primary vessel patency at 30 days. Researchers will also track device-related adverse events including bleeding, distal embolization, serious adverse events, and mortality up to 180 days post-procedure. Participants will be involved in follow-up assessments to evaluate these outcomes and safety measures over time.

Researchers are evaluating the safety and effectiveness of the VARIPULSE pulsed field ablation PFA catheter compared to the FDA-approved FARAWAVE PFA catheter in people with symptomatic persistent atrial fibrillation PsAF, a condition characterized by continuous irregular and rapid heartbeats lasting more than 7 days without stopping on its own. This randomized controlled trial aims to compare these two devices used in catheter ablation to treat PsAF. Participants with PsAF will undergo catheter ablation using either the VARIPULSE catheter or the FARAWAVE catheter. After the ablation procedure, they will be followed for up to 12 months to monitor outcomes. The study involves two parallel groups receiving one of the two PFA devices during the ablation treatment. During the study, participants will be assessed for early adverse events within 7 days after the procedure and monitored for occurrences of atrial tachyarrhythmia episodes starting from day 61 onward. Quality of life changes will also be measured at baseline and 6 months after the procedure using a specific questionnaire. Follow-up includes regular testing and monitoring to evaluate the safety and performance of the catheters over the 12-month period.

Researchers are evaluating the consistency of immune responses to three different batches of an investigational chickenpox vaccine called VNS vaccine in healthy children aged 12 to 15 months who have not had chickenpox or received a chickenpox vaccine before. The study also compares the safety and immune response of the VNS vaccine to an approved chickenpox vaccine known as Varivax. This Phase 3a study is sponsored by GlaxoSmithKline and aims to better understand the immune protection provided by these vaccines. Participants are randomly assigned to receive one dose of either one of the three investigational VNS vaccine lots or one of two lots of the marketed Varivax vaccine. Along with the chickenpox vaccine, they also receive one dose each of measles, mumps, and rubella MMR vaccine, hepatitis A vaccine HAV, and a pneumococcal conjugate vaccine PCV which could be PCV 13, Vaxneuvance, or PCV 20 depending on availability and country recommendations. All vaccines are given on Day 1 of the study. During the study, researchers monitor the participants immune responses by measuring antibodies against varicella zoster virus VZV and other vaccine components at Day 43. They also track safety by recording any side effects or adverse events from Day 1 to Day 181. The study includes diary reports by parents and regular clinical evaluations to assess immune response and safety outcomes. Participation involves a single vaccination visit and follow-up assessments over approximately six months.

Researchers are exploring whether the virus that causes COVID-19, called SARS-CoV-2, is present in the stool of infected patients. The study aims to understand the role of gut flora during and after COVID-19 infection by examining stool samples for viral shedding. This non-interventional pilot study is led by ProgenaBiome and focuses on the gastrointestinal microbiome in people diagnosed with COVID-19. Participants will provide stool samples that will be analyzed to sequence the microbiome. Samples will be collected during treatment for COVID-19 and again after treatment to determine if and when the virus is shed in the stool. The study involves observing the general populations microbiome through these samples without any intervention or treatment imposed. During the study, participants will have their stool microbiome sequenced to analyze the relative abundance of microbes and correlate it with the disease over the course of one year. Researchers will validate sequencing methods and monitor the gut microbiome changes. The study includes follow-up assessments and does not involve any active treatment, focusing instead on data collection and analysis over the study period.

Researchers are evaluating the activity and safety of barzolvolimab compared to placebo in adults with cold induced urticaria or symptomatic dermographism who continue to have symptoms despite using H1-antihistamines. This Phase 3, randomized, double-blind, placebo-controlled trial aims to understand how barzolvolimab works in these conditions that cause hives and itching triggered by cold or skin friction. Participants will first go through a screening period of up to 4 weeks to confirm eligibility. The treatment period lasts 52 weeks and has two parts for the first 24 weeks, patients receive either barzolvolimab or placebo by subcutaneous injection every 4 weeks, with an initial barzolvolimab dose of 450mg followed by 150mg doses. For the next 28 weeks, all patients receive 300mg barzolvolimab every 8 weeks. After treatment, there is a 16-week follow-up period during which participants are observed without receiving study drug. During the study, participants will have provocation testing to measure responses at various time points, including weeks 4, 12, and 24. Researchers will assess symptoms like itch and hives and measure thresholds related to cold and friction triggers. Participants will complete daily symptom diaries and attend regular visits for safety monitoring and assessments. The main outcome is a complete response to provocation testing at week 12. Overall participation lasts about 1 year including screening, treatment, and follow-up.
