Abstract

OBJECTIVES:This study sought to examine the efficacy of ranolazine versus placebo on weekly angina frequency and sublingual nitroglycerin use in subjects with type 2 diabetes mellitus, coronary artery disease (CAD), and chronic stable angina who remain symptomatic despite treatment with up to 2 antianginal agents. BACKGROUND: Patients with diabetes have more extensive CAD than those without diabetes, and a high burden of angina. Ranolazine is not only effective in treating angina but also may improve glycemic control, thus providing several potential benefits in this high-risk group. We conducted a randomized trial to test the antianginal benefit of ranolazine in patients with diabetes and stable angina. METHODS: TERISA (Type 2 Diabetes Evaluation of Ranolazine in Subjects With Chronic Stable Angina) was an international, randomized, double-blind trial of ranolazine versus placebo in patients with diabetes, CAD, and stable angina treated with 1 to 2 antianginals. After a single-blind, 4-week placebo run-in, patients were randomized to 8 weeks of double-blind ranolazine (target dose 1000 mg bid) or placebo. Anginal episodes and nitroglycerin use were recorded with daily entry into a novel electronic diary. Primary outcome was the average weekly number of anginal episodes over the last 6 weeks of the study. RESULTS: A total of 949 patients were randomized across 104 centers in 14 countries. Mean age was 64 years, 61% were men, mean diabetes duration was 7.5 years, and mean baseline HbA1c was 7.3%. Electronic diary data capture was 98% in both groups. Weekly angina frequency was significantly lower with ranolazine versus placebo (3.8 [95% confidence interval (CI): 3.6 to 4.1] episodes vs. 4.3 [95% CI: 4.0 to 4.5] episodes, p = 0.008), as was the weekly sublingual nitroglycerin use (1.7 [95% CI: 1.6 to 1.9] doses vs. 2.1 [95% CI: 1.9 to 2.3] doses, p = 0.003). There was no difference in the incidence of serious adverse events between groups. CONCLUSIONS: Among patients with diabetes and chronic angina despite treatment with up to 2 agents, ranolazine reduced angina and sublingual nitroglycerin use and was well tolerated.
