Efficacy of Ranolazine in Chronic Angina
  • Demonstrated in 5 double-blind, randomized, placebo-controlled studies
  • Dose and plasma concentration dependent
  • Observed in a broad population with severe
    coronary disease
  • Not dependent upon decreases in blood pressure or heart rate
  • At least as great as atenolol 100 mg qd
  • In patients on atenolol or diltiazem at doses considered optimal by their physicians

Studies Demonstrating
Efficacy of Ranolazine
  • Two pivotal Phase 3 studies of ranolazine SR
    • MARISA: monotherapy, 191 randomized
    • CARISA: combination, 823 randomized
    • 1° efficacy variable: trough exercise duration
  • Three supportive studies of ranolazine IR

Monotherapy Assessment of Ranolazine In Stable Angina
MARISA (CVT 3031)
  • Patients withdrawn from other anti-anginals
    (N = 191 randomized)
  • Randomized, double-blind, 4-period crossover
    • 1-wk treatment periods
    • Placebo vs 500, 1000, and 1500 mg bid
  • Exercise tests after each week of treatment
    • At trough (12 hr after dosing)
    • At peak      (4 hr after dosing)

Monotherapy With Ranolazine Increases Exercise Performance at Trough and Peak
MARISA (CVT 3031)
8
Combination Assessment of
Ranolazine In Stable Angina
CARISA (CVT 3033)
  • Randomization criteria identical to MARISA except for background therapy
    • Atenolol 50 mg qd (n = 354), or
    • Amlodipine 5 mg qd (n = 256), or
    • Diltiazem CD 180 mg qd (n = 213)
  • Three parallel groups for 12 wk of treatment
    • Placebo
    • Ranolazine 750 mg bid
    • Ranolazine 1000 mg bid
  • Exercise testing
    • At trough after 2, 6, and 12 wk of treatment
    • At peak after 2 and 12 wk of treatment

Ranolazine Concentration Predicts Response
Across the Chronic Angina Population—
Population-Based Analysis of Exercise Duration
  • Four double-blind, placebo-controlled studies
    • MARISA, CARISA and 2 IR studies
    • 1397 patients (1073 men, 324 women)
    • 10,998 ETT-plasma concentration pairs
  • No influence on concentration-response
    • Demographic factors: age, weight, and race
    • Concurrent diseases: CHF class, diabetes
    • Background anti-anginal therapy
  • Men and women respond differently
    • Women: 6.4 sec/1000 ng/mL, 95% CI (3.1, 9.7)
    • Men: 16.8 sec/1000 ng/mL, 95% CI (14.6, 19.0)
13
Anti-Anginal Effects of
Ranolazine SR in Women
  • Significant increase in exercise duration
    • 6.4 sec per 1000 ng/mL, 95% CI (3.1, 9.7)
14
Exercise Duration by Subgroup—
Borderline Vital Signs or AV Conduction†
MARISA (CVT 3031) and CARISA (CVT 3033)
15
Ranolazine Is Effective Across a Broad Spectrum of Chronic Angina Patients
Subgroups Often Intolerant of Other Anti-Anginals
  • Subgroups in which the effect of ranolazine appears consistent with the effect demonstrated in all patients:
    • Borderline vital signs or AV conduction†
    • Reactive airway disease
    • Congestive heart failure
    • Diabetes
16
Ranolazine Is at Least as Effective as Atenolol 100 mg Daily
RAN080

Ranolazine With Atenolol or Diltiazem
RAN072
  • “… patients … receiving an optimal dose of … beta blocker or diltiazem and stabilised at this optimal regimen for at least 7 days.”
  • 2-period, double-blind, crossover design
    • Exercise tests 2.5 to 3 hr after dosing
    • Both ranolazine and background Rx at peak
  • Efficacy with 240 mg IR single dose (N = 25)
    • 15 on atenolol (90 ± 21 mg qd)
    • 10 on diltiazem (186 ± 19 mg qd)

Summary—Anti-Anginal and Anti-Ischemic Efficacy of Ranolazine
  • Dose and plasma concentration dependent
  • Consistent throughout a broad population
    of chronic angina patients
  • Not dependent on decreases in blood pressure
    or heart rate
  • At least as great as atenolol 100 mg qd (RAN080)
  • In patients on atenolol or diltiazem at doses considered optimal by their physicians (RAN072)
