Peripheral Artery Disease (PAD)

Researchers are evaluating the safety and early effectiveness of an injectable drug called IMC-001 in improving the stability of atherosclerotic plaques in patients diagnosed with acute coronary syndrome ACS, which includes conditions like acute myocardial infarction or unstable angina. This early phase 1, randomized, double-blind, placebo-controlled study is being conducted at two centers and aims to better understand how IMC-001 affects plaque stability in these patients. The study involves two dose groups with nine subjects each, where six receive IMC-001 plus optimal medical therapy and three receive a placebo plus optimal medical therapy. Participants will receive injections of either IMC-001 or placebo alongside standard treatments for coronary artery disease. The trial includes a dose escalation design to assess safety and preliminary efficacy. Participants will be monitored for changes in coronary artery low-attenuation plaque volume using coronary computed tomography angiography CCTA at baseline and again six months after treatment. The study will track safety, plaque volume changes, and other clinical assessments during the treatment and follow-up periods. The total participation duration includes the treatment phase and a six-month evaluation after dosing to assess the primary outcome measure.

Researchers are evaluating whether using an automated Carbon Dioxide CO2 injection system during infrainguinal peripheral vascular interventions PVI can reduce major adverse kidney events within 90 days in patients at moderately increased risk for contrast-associated acute kidney injury CA-AKI. This Phase 3 randomized controlled trial compares a CO2-based contrast medium sparing strategy to the standard use of iodinated contrast media in patients with peripheral vascular and kidney diseases. Participants are randomly assigned to one of two groups. The intervention group receives PVI using an automated CO2 injection system as the primary contrast agent, with iodinated contrast media available as a backup if image quality is insufficient or if the patient cannot tolerate CO2 angiography. The control group undergoes routine PVI using iodinated contrast media according to local standards, avoiding high-osmolar contrast agents. All patients are followed for up to 12 months after their procedure. During the study, participants undergo the planned PVI procedure with either contrast method. Researchers carefully record the amount and reasons for any iodinated contrast media used in the CO2 group. Patients are monitored for kidney-related outcomes, focusing on major adverse kidney events up to 90 days after the intervention. The trial includes ongoing follow-up assessments to evaluate safety and effectiveness over one year.

Researchers are evaluating a new therapy approach called MOBILE to improve walking ability in children and teens with Cerebral Palsy. This study aims to find out if the therapy is acceptable and helpful to both the children and their families when provided in a community setting. The key questions include whether participants tolerate the therapy, if families find it manageable, and if children complete all therapy sessions and assessments as planned over the course of the study. The therapy uses motor learning principles to target each childs specific walking goal. Participants will complete a total of 30 hours of therapy over 6 weeks, with at least 24 hours conducted in a clinic. The remaining hours can be done through a home program. This flexible format allows children to choose how they complete their therapy sessions while focusing on improving their walking patterns. During the study, children will be assessed before and after therapy to see if they meet their walking goals. Researchers will also interview participants about their experience with the therapy. Various outcome measures will be tracked over 2 years, including recruitment, adherence, retention, adverse events, fidelity to the intervention, and the acceptability of the therapy. Functional walking tests and quality of life assessments will be done at baseline, post-intervention, and at a 3-month follow-up. Participants are involved in therapy sessions, assessments, and interviews throughout the study period.

Researchers are conducting a multi-center clinical study to assess artificial intelligence AI algorithms for measuring heart function and size using echocardiography. The study aims to compare AI measurements with those of physicians at different experience levels, evaluate the accuracy and stability of AI, and explore its use in complex heart conditions like cardiomyopathy, valve disease, and coronary heart disease. The goal is to improve diagnostic consistency and clinical workflows across medical centers. The study involves measuring cardiac chamber size and function in 1600 participants using AI, senior physicians, and intermediate physicians. All measurements are made with Mindray ultrasonic machines. AI and intermediate physician results are completed within one day after data collection, while senior physician results are completed within one month. The study will establish a standardized reference system for AI-assisted echocardiographic measurements and evaluate AIs performance in special cases. Participants will undergo echocardiographic scans with measurements of left and right ventricular size and function, Doppler ultrasound indicators, and valve annulus displacements. Researchers will analyze data to compare AI and physician measurements, assess measurement deviations, and evaluate AIs efficiency in reducing analysis time. The study will run until July 2026, with ongoing data collection and analysis across multiple centers, aiming to promote wider clinical application of AI technology for cardiovascular disease diagnosis.

Researchers are evaluating the efficacy and safety of intravenously administered YN001 in adults diagnosed with coronary atherosclerosis who are also receiving background therapy for managing cardiovascular risk factors. This multinational, multicenter, phase 2b clinical trial is randomized, double-blind, and placebo-controlled to compare YN001 with placebo in this patient population. Participants will be randomly assigned to receive one of three doses of YN001 or matching placebo intravenously once weekly for 13 weeks. The doses include 40mg, 20mg, or 0mg placebo. The study consists of up to a 12-week screening and baseline period, a 12-week blinded treatment period, a 30-day safety follow-up, and a long-term follow-up extending to approximately two years after randomization. During the study, participants will undergo various assessments including imaging to measure changes in coronary non-calcified plaque volume, carotid intima-media thickness, and plaque characteristics at multiple time points. Safety and immunogenicity will be monitored alongside pharmacokinetic analyses. The primary outcome focuses on relative change in coronary NCPV at week 13. Participants will be followed for up to 96 weeks to evaluate major adverse cardiac events and long-term safety.

This research investigates the safety and performance of various Vascular Grafts, including FlowWeave Bioseal, FlowNit Bioseal, FlowLine Bipore, and FlowLine Bipore Heparin, in treating arterial diseases such as dissection, aneurysm, intramural hematoma, penetrating aortic ulcer, contained rupture, and stenosis affecting the aorta or peripheral arteries in the lower limbs. It also covers the use of these grafts for debranching head vessels and as arterio-venous shunts. The study is observational and focuses on patients who have already received these grafts. Patients included in this study have received one of these Vascular Grafts as part of their treatment for arterial conditions. The study collects data from routine care, including interventions like open repair of the aorta and peripheral arteries. The data collection period lasts approximately 60 months plus an additional 6 months beyond the last follow-up visit, depending on each patients timeline. Participants medical records and observations gathered during standard care visits will be used for data collection. Researchers will monitor outcomes such as 30-day mortality, longer-term mortality at intervals up to 60 months, graft-related adverse events, hemorrhage, stenosis or occlusion, graft patency, pseudoaneurysm formation, infections, sepsis, and stroke occurrences. Patients will be observed throughout this period while continuing their usual care, providing a comprehensive view of graft performance and safety over time.

Researchers are evaluating a preventive, multidisciplinary primary care intervention designed around a therapeutic garden to assess its acceptability among patients with cardio-neurovascular diseases. This study focuses on individuals suffering from various vascular conditions, including atrial fibrillation, heart failure NYHA Class II, cardiomyopathies, ischemic stroke, and resistant hypertension. The main goal is to understand how patients and those involved in their care respond to this novel intervention. The intervention consists of a 6-month program that includes gardening activities, adapted physical exercise, nutritional workshops, and questionnaires to gather feedback. Participants may either take part in this multidisciplinary preventive action or choose not to receive the intervention but still complete questionnaires explaining their reasons. The study compares these two groups to identify acceptance rates and factors influencing participation. Participants will be involved for six months, during which their acceptance of the intervention and any obstacles or facilitators will be recorded. Researchers will assess the impact of the program through questionnaires and follow-up evaluations. The study monitors participants from enrollment through the end of treatment, aiming to gather comprehensive data on the interventions feasibility and effects on patients with cardio-neurovascular conditions.

Researchers are investigating the safety and effectiveness of the Renzan14 Peripheral Stent System in treating patients with femoro-popliteal disease, a type of peripheral arterial disease affecting the leg arteries. This prospective, multicenter, single-arm study plans to include about 100 patients eligible for treatment with this stent. The study focuses on evaluating a modern nitinol stent designed for complex lesions where drug-coated balloons and drug-eluting stents may be less effective or raise concerns about toxicity. The Renzan stent is a self-expanding nitinol device pre-mounted on a catheter designed for precise placement in the affected arteries. It consists of two layers of braided nitinol wire mesh with radiopaque markers to assist in positioning during the procedure. The stent can be partly recaptured during placement if needed. This study observes patients undergoing endovascular implantation of the Renzan stent without comparison groups, focusing on the devices performance and safety after treatment. Participants will be followed for assessments of safety and effectiveness, including measurements at 30 days and up to 12 months after the procedure. Key evaluations include device and procedural success during implantation, rates of death, need for further treatment of the treated artery, artery openness, limb ischemia improvement, major adverse events, and limb amputation at multiple time points up to 36 months. Patients will be monitored closely with follow-up visits to track these outcomes and the long-term performance of the stent.

Researchers are investigating whether a coronary CT angiography CCTA-guided calcium modification approach can improve the treatment of patients with significant calcified coronary artery disease undergoing percutaneous coronary intervention PCI. This prospective, multicenter, randomized controlled trial compares the CCTA-guided strategy to the current standard of care using intravascular ultrasound IVUS-guided PCI. The study aims to see if the CT-based approach can improve procedural efficiency and stent results while maintaining similar clinical outcomes to IVUS guidance. Participants will be randomly assigned to one of two groups one using CCTA to inform calcium modification and plaque preparation before PCI, and the other using IVUS imaging to guide the procedure. Both groups undergo imaging to evaluate lesion characteristics before the procedure, with IVUS also used after stent placement to confirm correct implantation. The trial includes two main goals showing superiority in minimal stent area by IVUS and demonstrating non-inferiority in 12-month target vessel failure rates. During the study, participants receive imaging and PCI treatments according to their assigned group. Researchers will collect data on procedure time, radiation exposure, contrast volume, and detailed stent measurements. Clinical safety outcomes such as myocardial infarction and stent thrombosis will be monitored up to 12 months, along with patient-reported angina symptoms. Total participant involvement spans the procedure and follow-up assessments to evaluate both imaging and clinical outcomes.

This clinical trial is studying patients with combined pre- and post-capillary pulmonary hypertension CpcPH linked to left heart disease LHD. It aims to evaluate the safety and effectiveness of a new device called the Multi-Pole Pulmonary Artery Radiofrequency Ablation Enhancor System, compared to standard medical therapy. The study includes patients with chronic heart failure who are stable and already receiving the best available medical treatments for left heart failure. Participants will be randomly assigned to one of two groups the intervention group will receive pulmonary artery denervation PADN using the Enhancor System plus guideline-directed medical therapy GDMT, while the control group will undergo a placebo procedure plus GDMT. Before randomization, some operators may perform up to two roll-in PADN procedures to gain experience. Participants will be followed for 3 years, with clinical assessments at 1, 6, 12, 24, and 36 months. Control subjects who experience a primary efficacy endpoint event may cross over to receive PADN after 24 months if eligible. During the study, participants will undergo various assessments including heart function tests, walking distance tests, biomarker blood tests NT-proBNP, and quality of life questionnaires Kansas City Cardiomyopathy Questionnaire at several time points. Safety will be monitored closely, especially within 30 days after the procedure. Researchers will track heart failure events, hospitalizations, device implantations, heart transplantations, and cardiovascular deaths over the 3 years. Participants are expected to comply with medication and follow-up visits throughout the study.
