Ranolazine Implantable Cardioverter-Defibrillator Trial

Completed · Phase 3 · Has a placebo group

Conditions studied: Ischemic Cardiomyopathy, Nonischemic Cardiomyopathy, Heart Failure

In brief

The purpose of the study is to see how effective a drug called ranolazine is in reducing the risk of ventricular arrhythmia and death in people with implantable cardioverter-defibrillators (ICDs). This drug will be used with standard medications that is routinely prescribed in enrolled patients.

Who can join

Age: 21 and older. Sex: any. Healthy volunteers: not accepted.

You may qualify if…

• 1,440 high-risk patients with ischemic/nonischemic cardiomyopathy who receive their ICDs as standard of care for primary or secondary prevention of mortality following approved indications for ICD therapy. High-risk patients will be defined as:
• Secondary Prevention Patients Subjects with ischemic or nonischemic cardiomyopathy, qualified for or with existing ICD (or CRT-D) after documented VT/VF or cardiac arrest (secondary prevention of mortality). Secondary prevention subjects with existing implants are eligible regardless of when the implant was received (subjects could be recruited from outpatient clinics or from inpatient activity including during re-implant or other procedures).
• Primary Prevention Patients
• Patients with primary prevention indications for ischemic or non-ischemic cardiomyopathy with EF≤35%, with existing devices (ICD/CRT-D), regardless of when the device was implanted, who have experienced at least ONE episode of VT/VF appropriately treated with ICD therapy (ATP or shock) or had untreated NSVT lasting at least 10 beats with heart rate of at least 170 bpm, documented by electrogram of their implanted device.
• Patients with ischemic or non-ischemic cardiomyopathy with EF≤35%, who have been implanted within the last 2 years (initial ICD/CRT-D implants, including upgrades from pacemakers) who have NOT experienced VT/VF treated with ICD therapy (ATP or shock), AND who have one of the following additional criteria: BUN≥26 mg/dl or QRS>120ms or Atrial Fibrillation or NSVT documented by ECG/Holter or >500 Ventricular Premature Beats (VPBs)documented in a 24-hour Holter.
• Stable optimal pharmacologic therapy for the cardiac condition
• Age: equal to 21 years without upper limit

You may not qualify if…

• Patient receiving first device with coronary artery bypass graft surgery within the last 3 calendar months prior to date consent obtained
• Patients receiving first device with percutaneous coronary intervention within the last 1 calendar month prior to date consent obtained
• Patient receiving first device with enzyme-positive myocardial infarction with the past 3 calendar months prior to date consent obtained
• Patient receiving first device with angiographic evidence of coronary disease who are candidates for coronary revascularization and are likely to undergo coronary artery bypass graft surgery or percutaneous coronary intervention in the foreseeable future
• Patient in NYHA Class IV
• Patients receiving prophylactic ablation of ventricular substrate
• Patients with preexisting QTc prolongation >550ms
• Patients on strong CYP3A inhibitors (including ketoconazole, itraconazole, clarithromycin, nefazodone, nelfinavir, ritonavir, indinavir and saquinavir and moderate CYP3A inhibitors, including, diltiazem, verapamil, aprepitant, erythromycin, fluconazole and grapefruit juice or grapefruit-containing products.
• Patients on CYP3A inducers such as rifampin, rifabutin, rifapentine, phenobarbital, phenytoin, carbamazepine and St.John's wort
• Patients with inherited arrhythmia disorders such as Brugada's, ARVD, LQTS or hypertrophic cardiomyopathy
• Patient who is pregnant or plans to become pregnant during the course of the trial (patients at child bearing age who use prescribed pharmaceutical contraceptives could be enrolled)
• Patient with irreversible brain damage from preexisting cerebral disease
• Patient with presence of any disease, other than the patient's cardiac disease, associated with a reduced likelihood of survival for the duration of the trial, e.g., cancer, uremia, liver failure, etc.
• Patient with chronic renal disease with creatinine >2.5 mg/dl or creatinine clearance <30 ml/min
• Patient participating in any other clinical trial
• Patient unwilling or unable to cooperate with the protocol
• Patient who lives at such a distance from the clinic that travel for follow-up visits would be unusually difficult
• Patient who does not anticipate being a resident of the area for the scheduled duration of the trial
• Patients who are decisionally impaired adults, those of questionable capacity, and those who cannot consent for themselves will not be recruited for this study.
• Patient unwilling to sign the consent for participation
