Research Trials

Prevention of Cardiovascular Events (eg, Death From Heart or Vascular Disease, Heart Attack, or Stroke) in Patients With Prior Heart Attack Using Ticagrelor Compared to Placebo on a Background of Aspirin - This study is being carried out to see if a new drug called ticagrelor given twice daily in addition to the ASA therapy decreases the frequency of cardiovascular events (e.g., death from heart disease, heart attack, or stroke).

IMPACT: The IMPACT of BIOTRONIK Home Monitoring Guided Anticoagulation on Stroke Risk in Patients With Implanted ICD and CRT-D Devices - The IMPACT Study will investigate the clinical benefit of the combined use of BIOTRONIK Home Monitoring (HM) technology and a predefined anticoagulation plan compared to conventional device evaluation and physician-directed anticoagulation in patients with implanted dual-chamber defibrillators or cardiac resynchronization therapy devices.

ATTAIN SUCCESS TRIAL - The purpose of the study is to assess lead implant success and complication rate using the Medtronic Attain Family of left-heart leads and delivery catheters.

TRANSLATE-ACS: Treatment With Adenosine Diphosphate (ADP) Receptor Inhibitors: Longitudinal Assessment of Treatment Patterns and Events After Acute Coronary Syndrome - a prospective, observational longitudinal study to evaluate the real world effectiveness and use of prasugrel and other ADP receptor inhibitor therapies among myocardial infarction (MI) patients treated with percutaneous coronary intervention (PCI) during the index hospitalization. Patient management and treatment decisions are at the discretion of the care team per routine clinical practice.

The following are previous trials, which may be ongiong. Recruitment for new patients is closed:
CHAMPION: CardioMEMS Heart Sensor Allows Monitoring of Pressure to Improve Outcomes in NYHA Class III Heart Failure Patients - This is a prospective, multi-center, randomized, single-blind clinical trial conducted in the United States (US). The objective of the study is to evaluate the safety and efficacy of the HF Pressure Measurement System in reducing heart failure (HF) related hospitalizations in a subset of subjects suffering from HF.

SATURN: CRESTOR Athero Imaging Head to Head IVUS Study - A 104-week, randomized, double-blind, parallel group, multi-center Phase IIIb study comparing the effects of treatment with rosuvastatin 40 mg or atorvastatin 80mg on atherosclerotic disease burden as measured by intravascular ultrasound in patients with coronary artery disease.

ZESCA: Zyban as an Effective Smoking Cessation Aid for Patients Following an Acute Coronary Syndrome: The ZESCA Trial - Patients who continue to smoke after a heart attack have a 35% increased risk of a recurrent event or death compared with those who quit. Many patients attempt to stop smoking after a heart attack, but relapse rates approach 66%. A variety of smoking cessation aids have been shown to be effective for the general population. However, bupropion is the only non-nicotine replacement therapy shown to improve abstinence rates in healthy young smokers. Furthermore, nicotine replacement therapies (NRTs) are contraindicated in the immediate period following a heart attack because of the undesirable effects of nicotine. Although bupropion has been successfully used to reduce smoking rates in healthy young populations, its efficacy and safety in the setting of patients recovering from an ACS is unknown. These patients, if they continue to smoke, are at exceptionally high risk for recurrent cardiac events. If bupropion is effective in this population, it will have a major impact on secondary prevention of recurrent clinical events in patients who suffer a heart attack.

: Examining Outcomes in Subjects With Acute Coronary Syndrome:Vytorin (Ezetimibe/Simvastatin) vs Simvastatin (Study P04103)
 - This is a randomized, active-control, double-blind study of subjects with stabilized high-risk acute coronary syndrome (ACS). The primary objective is to evaluate the clinical benefit of Ezetimibe/Simvastatin Combination 10/40 (single tablet, under the brand VYTORIN in the United States) compared with Simvastatin 40 mg. Clinical benefit will be defined as the reduction in the risk of the occurrence of the composite endpoint of CV death, major coronary events, and stroke.

A Comparison of AZD6140 and Clopidogrel in Patients With Acute Coronary Syndrome (PLATO) - AZD6140 is a new, reversible, anti-platelet medication. Anti-platelet medications work to prevent the formation of blood clots. AZD6140 is being developed as a treatment for patients with acute coronary syndrome (ACS). ACS is a term that is used to describe both heart attacks in progress or the imminent threat of a heart attack. ACS is usually caused by the formation of a blood clot in an artery that partially or totally blocks the blood supply to a portion of the heart muscle. AZD6140 will be compared with clopidogrel to determine which drug, when either is used in conjunction with aspirin, is better at reducing deaths from vascular causes, future heart attacks and/or strokes in patients with ACS.

Randomized Evaluation of Long Term Anticoagulant Therapy (RE-LY) With Dabigatran Etexilate - The primary objective of this trial is to demonstrate the efficacy and safety of dabigatran etexilate in patients with non-valvular atrial fibrillation for the prevention of stroke and systemic embolism.

A Study of RO4607381 in Stable Coronary Heart Disease Patients With Recent Acute Coronary Syndrome (DAL-Outcomes) - This study will evaluate the potential of RO4607381 to reduce cardiovascular morbidity and mortality in stable coronary heart disease patients with recent Acute Coronary Syndrome (ACS) and evaluate the long term safety profile of the drug. Eligible patients in stable condition will be randomized to receive either RO4607381 600mg po or placebo po, daily, together with a background of standard medication for ACS (including aspirin, antihypertensives and statins). The anticipated time on study treatment is 2+ years, and the target sample size is 500+ individuals.
