26 Clinical Trials for Various Conditions

* The goal of the screening trial is to determine whether early screening for atrial fibrillation improves outcomes, including lowering the chance of death, hospitalization for stroke, blood clots, heart failure, heart attack, and severe bleeding reduces the risk of stroke or heart failure. * Atrial fibrillation is a common heart condition in which one of the heart chambers doesn't follow a normal rhythm. Blood clots can form as a result, and they can travel to the brain and cause strokes, or to other organs. * Almost everyone with atrial fibrillation is treated with drugs called anticoagulants ("blood thinners") to reduce the risk of stroke. These drugs also increase the risk of bleeding. * Testing for atrial fibrillation is usually done for patients who have symptoms of an irregular or unusually fast or slow heartbeat, often called "palpitations" or a sensation of the heart pounding or stopping for a short period of time. * What is not known is whether screening people who do not have symptoms of atrial fibrillation, but who are at above-average risk of getting atrial fibrillation, will reduce death, hospitalization for stroke, blood clots, heart failure more than it increases hospitalization for severe bleeding. * People who participate in the trial who are selected by chance to receive screening will wear a small heart-rate monitor (Zio Patch) on their skin for 14 days and then return it to the manufacturer. Their doctors will be notified about the results and will make decisions about any treatment to recommend. * The screening trial is expected to enroll about 24,000 VA patients nationwide and to last 7 years, but each person's active participation in the trial is completed after sending in the Zio Patch. After that, the study team will just collect information from the participant's electronic medical records.
This is a Phase 3, multicenter, randomized, double-blind, placebo-controlled clinical study designed to evaluate the efficacy and safety of FlecIH-103 (flecainide acetate inhalation solution) compared with placebo in patients with recent-onset, symptomatic newly diagnosed or paroxysmal AF. Approximately 400 patients are expected to be enrolled in this study. Patients will be randomized 3:1 to receive FlecIH-103 at a total dose of up to 120 mg estimated total lung dose (eTLD) (n=300) or placebo inhalation solution (n=100). Randomization will be stratified by geographic region (US and ex-US) and duration of symptoms of the current AF episode (≥1 hour to ≤24 hours and \>24 hours to ≤48 hours).

The 2006 American Heart Association / American Stroke Association Council on Stroke Guidelines for Prevention of Stroke in Patients With Ischemic Stroke or Transient Ischemic recommended that patients with cryptogenic stroke take antithrombotic drugs (i.e. aspirin) in order to prevent a second stroke. When a stroke patient is found to have atrial fibrillation (AF), the guidelines recommend oral anticoagulation due to its superior efficacy over aspirin for stroke prevention. Physicians can best optimize the use of medicines only if they can precisely and correctly diagnose a patient's AF. The purpose of this study is to evaluate the time to first AF by 6 months' continuous rhythm monitoring versus control treatment in subjects with a recent cryptogenic stroke or Transient Ischemic Attack (TIA) without history of AF.
