Pulmonary Embolism clinical trials at UC Health

5 in progress, 1 open to eligible people

  • Hokusai Study in Pediatric Patients With Confirmed Venous Thromboembolism (VTE)

    open to eligible people ages up to 17 years

    This is an event driven Phase 3, prospective, randomized, open-label, blinded endpoint evaluation (PROBE) parallel group study in subjects with confirmed VTE. This study is designed to evaluate the pharmacokinetics (PK) and pharmacodynamics (PD) of edoxaban and to compare the efficacy and safety of edoxaban against standard of care in pediatric subjects with confirmed VTE.

  • Comparative Effectiveness of Pulmonary Embolism Prevention After Hip and Knee Replacement

    Sorry, in progress, not accepting new patients

    PEPPER is a randomized study comparing the three most commonly used anticoagulants in North America in patients who have elected to undergo primary or revision hip or knee joint replacement surgery. The anticoagulants being compared are enteric coated aspirin, low intensity warfarin, and rivaroxaban.

  • Direct Oral Anticoagulants (DOACs) Versus LMWH +/- Warfarin for VTE in Cancer

    Sorry, in progress, not accepting new patients

    The overarching objective of the study is to determine the effectiveness of LMWH/ warfarin vs. DOAC anticoagulation for preventing recurrent VTE in cancer patients. The intervention strategy is Direct Oral AntiCoagulants (DOAC) therapy with edoxaban, apixaban, rivaroxaban, or dabigatran. The comparator is low molecular weight heparin (LMWH) alone or with warfarin. The information gained will empower cancer patients and physicians to make more informed choices about anticoagulation strategies to manage VTE.

  • Pilot Study to Evaluate the Role of EBUS in the Diagnosis of Acute PE in Critically Ill Patients

    Sorry, accepting new patients by invitation only

    Acute pulmonary embolism (PE) in critically ill patients is common and often life threatening. The diagnosis of acute PE is often entertained in intensive care unit patients who develop unexplained hypotension or hypoxemia. Obtaining diagnostic confirmation of acute PE with a contrast-enhanced computed tomography of the chest (CT angiogram) may be difficult as patients are often too unstable for transport to the CT scanner or have renal insufficiency limiting the ability to receive intravenous contrast agents. Making or excluding the diagnosis of acute PE in these patients is critically important, as hemodynamic instability or right heart dysfunction, if due to PE, puts patients in the massive or submassive category and increased mortality risk. More aggressive therapies such as thrombolysis, extracorporeal membrane oxygenation or surgical embolectomy are often entertained. The investigators have previously described a case where endobronchial ultrasound (EBUS) was employed in the diagnostic algorithm of suspected acute PE and significantly affected treatment recommendations. The investigators believe that, in these patients, use of EBUS to assess for thrombotic occlusion of the central pulmonary vasculature can fill a critical gap in the decision tree for management of these patients. EBUS has become part of the diagnostic approach in a number of clinical situations, including the workup and staging of suspected malignancy, unexplained lymphadenopathy, and diagnosis of mediastinal and parabronchial masses. There is strong evidence that EBUS is equivalent to mediastinoscopy in the mediastinal staging of lung cancer. The number of physicians skilled and experienced in performance of EBUS has increased dramatically, and training in the procedure is frequently obtained in a pulmonary fellowship. To our knowledge, there have been no prospective studies that investigate the use of EBUS as a tool for the diagnosis of acute central pulmonary embolism in critically ill patients where obtaining diagnostic confirmation of this diagnosis with a contrast-enhanced computed tomography of the chest is not safe or feasible.

  • Predicting the Safety and Effectiveness of Inferior Vena Cava Filters

    Sorry, in progress, not accepting new patients

    PRESERVE is a multi-center, prospective, open-label, non-randomized investigation of commercially available IVC filters from 6 manufacturers placed in subjects for the prevention of pulmonary embolism (PE). This study will enroll approximately 1,800 IVC filter subjects at up to 60 sites in the US. All treated subjects will be evaluated at procedure, 3-months, 6-months (phone), 12-months, 18-months (phone), and 24-months post-procedure. The primary objective of this investigational device exemption (IDE) clinical investigation is to evaluate the safety and effectiveness of the commercially available IVC filters (retrievable and permanent) in subjects with clinical need for mechanical prophylaxis of PE with an IVC filter.
