- 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

- 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

- Patients withdrawn from other anti-anginals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)

- 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

- 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)

- 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

- “… 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)

- 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)

- Extent of exposure
- 2783 subjects/patients
- 1714 subject/patient yr
- Adverse events are generally dose dependent and manageable by typical
dose titration
- No evidence for an adverse effect of ranolazine on survival
