14 Clinical Trials for Various Conditions
This single site study evaluates the efficacy of ultrasound accelerated thrombolysis using EKOS Endovascular Device with a standard infusion of thrombolytics for treatment of PE
This study is focused on investigating the efficacy and safety of the FlowTriever device to treat low-risk submassive pulmonary embolism.
Acute pulmonary embolism (PE) accounts for 5-10% of in-hospital deaths. Systemic anticoagulation (AC) is the standard of care and thrombolysis is recommended for those at a higher mortality risk. Catheter-directed therapies, mainly standard infusion catheter thrombolysis (CDT) and ultrasound-accelerated thrombolysis (USAT), have been introduced as new more effective and safer treatment modalities. USAT is a modification of standard catheter lysis utilizing a system of local ultrasound to dissociate the fibrin matrix of the thrombus with simultaneous acoustic streaming of the thrombolytic agent, allowing more efficient thrombolysis. However, there is limited comparative effectiveness data against standard multi-side hole catheter infusion. More rapid clearance of pulmonary thrombus by USAT compared to standard CDT may prove to be clinically beneficial and cost effective. Alternatively, if thrombus clearance is similar, the cost of USAT may exceed the cost of CDT (equipment and disposables), without realization any advantage.
The study is an investigator-initiated trial comparing two different catheters (standard versus ultrasound assisted) for the treatment of acute high risk pulmonary embolism (blood clots in lung arteries with evidence or heart strain). Patients already planned for the procedure will be randomized to standard catheter-directed thrombolysis (CDT) or to ultrasound-assisted catheter thrombolysis (USAT). Both catheters are currently used routinely in practice for the treatment of pulmonary embolism, but it is not known if USAT is superior to standard CDT, the former being much more expensive and more commonly used. The purpose of the study is to learn about which catheter-directed therapy is more suitable for patients with pulmonary embolism (PE), who are candidates for both standard catheter directed therapy (CDT), and ultrasound-assisted catheter directed therapy (USAT), and to provide information regarding the cost effectiveness of the two different types of treatment. A total of 80 patients are planned to be recruited. All medication administration, procedures or in-hospital tests will be performed as routine clinical practice. The study will compare short term and long term outcomes: resolution of blood clots on CT scan, right ventricular size improvement, quality of life and symptoms at 3 and 12 months, and cost effectiveness.
This is a Phase 1b, double-blind (participants and Investigators), placebo-controlled, randomized, single-ascending dose, multi-center study to assess the safety, efficacy, tolerability, pharmacokinetics (PK), and pharmacodynamics (PD) of DS-1040b in participants with acute submassive pulmonary embolism.
The study will compare standard catheter directed thrombolysis to ultrasound accelerated thrombolysis for the treatment of acute submassive pulmonary embolism (PE). The study population will include patients eligible for catheter directed thrombolysis (CDT) for submassive PE. Subjects will be randomized to, either, standard catheter-directed thrombolysis or ultrasound-accelerated thrombolysis (USAT).
Patients with Submassive Pulmonary Embolism treated with ultra-sound therapy will have an improved right ventricular function 72 hours post treatment.
To demonstrate the efficacy and safety of the Bashir™ Endovascular Catheter for the administration of pharmaco-mechanical catheter directed therapy using pulse spray of r-tPA for the treatment of acute submassive pulmonary embolism
The purpose of this study is to determine if the EKOS EkoSonic® Endovascular Device when used in conjunction with recombinant tissue plasminogen activator (t-PA) as a treatment for acute PE will decrease the ratio of right ventricle (RV) to left ventricle (LV) diameter within 48 =/- 6 hours in participants with massive or submassive PE.
Evaluate the safety and effectiveness of the FlowTriever System for use in the removal of emboli from the pulmonary arteries in the treatment of acute pulmonary embolism.
Evaluation of the Safety and Efficacy of the Symphony Thrombectomy System in the Treatment of Pulmonary Embolism
To determine whether peripheral low dose systemic thrombolysis (PLST) is non-inferior to catheter directed acoustic pulse thrombolysis (ACDT) in improving RV function and reducing pulmonary artery pressures in submassive pulmonary embolism (PE)
A single center study to evaluate the effect of inhaled nitric oxide (iNO) on pulmonary dynamics in patients presenting with imaging confirmed intermediate/submassive or massive pulmonary embolism (PE). The target enrollment is 20 subjects at Ronald Reagan UCLA Medical Center. PE patients undergoing catheter-based intervention will be administered iNO during their intervention and pulmonary hemodynamic measurement will be measured before, during, and after iNO administration (Invasive Cohort). Patients who are not undergoing catheter-based intervention will also be administered iNO and will have pulmonary hemodynamics, blood pressure, and heart rate measured non-invasively (Non-Invasive Cohort).
