MERLIN-TIMI 36 is a multi-national, double-blind, randomized, placebo-controlled, parallel-group clinical trial designed to evaluate the efficacy and safety of ranolazine during acute and long-term treatment in approximately 5,500 patients with non-ST elevation acute coronary syndromes (ACS) treated with standard therapy. The primary efficacy endpoint in MERLIN-TIMI 36 is time to first occurrence of any element of the composite of cardiovascular death, myocardial infarction or recurrent ischemia in patients with non-ST elevation ACS receiving standard therapy. The study also evaluates the safety of long-term treatment with ranolazine compared to placebo.

Primary Outcome Measures:
  • Time to first occurrence of any element of the composite of cardiovascular death, myocardial infarction or recurrent ischemia through the end of the follow-up in non-ST elevation ACS. [ Time Frame: First occurrence ]

Secondary Outcome Measures:
  • Composite of cardiovascular death, myocardial infarction, or severe recurrent ischemia. Safety of long-term treatment with ranolazine compared to placebo; safety endpoints are death from any cause and symptomatic documented arrhythmia. [ Time Frame: First occurence ]

Ages Eligible for Study:   18 Years and older   (Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Hospitalized with non-ST elevation acute coronary syndrome
  • Ischemic symptoms (more than or equal to 5 minutes) at rest within 48 hours of study entry
  • At least one additional risk factor (e.g., elevated cardiac enzymes, ST-depression, diabetes)

Exclusion Criteria:

  • Persistent acute ST-segment elevation
  • Successful revascularization during the qualifying hospitalization, prior to study entry
  • Acute pulmonary edema, hypotension, or evidence of cardiogenic shock
  • Clinically significant liver disease
  • End stage kidney disease requiring dialysis
  • Concomitant use of drugs known to prolong the QT interval, or any digitalis drugs
  • Use at study entry of drugs that are strong inhibitors of cytochrome P450 3A4
  • Pregnant or lactating women, or women of child bearing potential not using an acceptable form of birth control

Additional study entry criteria will be evaluated during initial screening.
