  Show Detailed Description


Ages Eligible for Study:   40 Years and older   (Adult, Senior)
Sexes Eligible for Study:   Male
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Males age > 40 years.
  • Subjects must have chronic stable angina, meeting the labeled indications for ranolazine:

Ranolazine is indicated for the treatment of chronic angina. Ranolazine should be reserved for subjects who have not achieved an adequate response with other anti-anginal drugs.

  • Subjects must have a resting ankle brachial index (ABI) of < 0.90 with a post-exercise decrement of ≥ 10% in at least one leg, OR a resting ABI of ≥0.90 to ≤ 1.00 with a post-exercise decrement of ≥ 20% in at least one leg
  • The subject has provided written informed consent to participate, understands the requirements of the study, and agrees to return for the required assessments

Exclusion Criteria:

  • Non-atherosclerotic diseases of the peripheral circulation by clinical history
  • Unable to complete the first stage of the modified, extended Astrand treadmill protocol
  • Clinically significant ECG abnormalities or changes with exercise on the screening ECG
  • Evidence of critical limb ischemia (CLI)
  • Hepatic impairment (Child-Pugh Classes A [mild], B [moderate], or C [severe])
  • End stage renal disease requiring dialysis
  • Hemoglobin < 12 mg/dL.
  • Platelet count < 90,000/mL.
  • Planned surgical/endovascular intervention for coronary artery disease (CAD) or peripheral arterial disease (PAD) in the next 3 months
  • Maximal exercise is limited by symptoms other than claudication or angina
  • Significant mental illness or drug abuse within 30 days of enrollment that in the opinion of the Investigator could impact the subject's ability to successfully complete the trial
  • Known allergy to ranolazine
  • Pre-existing QTc prolongation on a resting electrocardiogram (ECG) at Screening due to the risk of worsening of this condition with the use of ranolazine
  • Treatment with QT prolonging drugs such as Class IA (e.g. quinidine) and Class III (e.g. sotalol, dofetilide), antiarrhythmics, amiodarone, and antipsychotics (e.g. thioridazine, ziprasidone)
  • Treatment with potent or moderately potent CYP3A inhibitors including ketoconazole and other azole antifungals, diltiazem, verapamil, macrolide antibiotics, cyclosporine, or human immunodeficiency virus (HIV) protease inhibitors
  • The subject has previously received ranolazine within the 6-months prior to enrollment
  • The subject has received an investigational drug within 90 days prior to enrollment
  • Type 1 or type 2 diabetes mellitus
  • Congestive Heart Failure, ≥ New York Heart Association (NYHA) Class III
  • History of oxygen dependent Chronic Obstructive Pulmonary Disease (COPD)
  • Body Mass Index (BMI) >35
