OBJECTIVES: To estimate the cost-effectiveness of ranolazine when added to
standard-of-care (SoC) antianginals compared with SoC alone in patients with
stable coronary disease experiencing ?3 attacks/week. SETTING: An economic model
utilising a UK health system perspective, a 1-month cycle-length and a 1-year
time horizon. PARTICIPANTS: Patients with stable coronary disease experiencing ?3
attacks/week starting in 1 of 4 angina frequency health states based on Seattle
Angina Questionnaire Angina Frequency (SAQAF) scores (100=no; 61-99=monthly;
31-60=weekly; 0-30=daily angina). INTERVENTION: Ranolazine added to SoC or SoC
alone. Patients were allowed to transition between SAQAF states (first cycle
only) or death (any cycle) based on probabilities derived from the randomised,
controlled Efficacy of Ranolazine in Chronic Angina trial and other studies.
Patients not responding to ranolazine in month 1 (not improving ?1 SAQAF health
state) discontinued ranolazine and were assumed to behave like SoC patients.
PRIMARY AND SECONDARY OUTCOMES MEASURES: Costs (£2014) and quality-adjusted
life-years (QALYs) for patients receiving and not receiving ranolazine. RESULTS:
Ranolazine patients lived a mean of 0.701 QALYs at a cost of £5208. Those not
receiving ranolazine lived 0.662 QALYs at a cost of £5318. The addition of
ranolazine to SoC was therefore a dominant economic strategy. The incremental
cost-effectiveness ratio was sensitive to ranolazine cost; exceeding £20,000/QALY
when ranolazine's cost was >£203/month. Ranolazine remained a dominant strategy
when indirect costs were included and mortality rates were assumed to increase
with worsening severity of SAQAF health states. Monte Carlo simulation found
ranolazine to be a dominant strategy in ?71% of 10,000 iterations. CONCLUSIONS:
Although UK-specific data on ranolazine's efficacy and safety are lacking, our
analysis suggest ranolazine added to SoC in patients with weekly or daily angina
is likely cost-effective from a UK health system perspective.
