Evaluation of Ranolazine in Patients with Type 2 Diabetes Mellitus and Chronic Stable Angina Results from the TERISA Randomized Clinical Trial Mikhail Kosiborod, Suzanne V. Arnold, John A. Spertus, Darren K. Mc. Guire, Yan Li, Patrick Yue, Ori Ben-Yehuda, Amos Katz, Phillip G. Jones, Ann Olmsted, Luiz Belardinelli, Bernard R. Chaitman On behalf of the TERISA Investigators
Funding • TERISA was sponsored by Gilead Sciences Inc. – Saint Luke’s Mid America Heart Institute received funding for independent data analysis from Gilead Sciences, Inc.
Background • Despite advances in therapy, chronic angina remains a common problem – Affects 8 million patients in the US – Negative impact on health status and Qo. L – Major driver of repeat hospitalizations and costs • Patients with diabetes have more extensive CAD, and greater angina burden than those without diabetes
Background • Ranolazine, an inhibitor of the late sodium current (late INa), is effective in treating chronic angina • Ranolazine may also lower fasting glucose and Hb. A 1 c • The anti-anginal efficacy of ranolazine in patients with diabetes has not been prospectively tested
TERISA: Primary Objective • Evaluate efficacy of ranolazine versus placebo on angina frequency in patients with type 2 diabetes, CAD, and chronic stable angina who remain symptomatic despite treatment with 1 or 2 antianginal medications
TERISA: Study Design • Run-in Phase: Single-blind placebo (4 weeks) • Treatment Phase: Randomized double-blind parallel group phase (8 weeks): ranolazine (target dose 1000 mg bid vs. matching placebo) Run-in Phase* Treatment Phase 4 weeks 8 weeks Wk 2 visit Wk 8 visit FU safety phone call Ranolazine Randomization Screening FU – 2 wks Wk 2 visit Wk 8 visit Placebo Antianginal Background Therapy *Subjects taking >2 antianginal medications or disallowed antianginal agents were allowed additional 2 week washout period prior to the run-in phase FU safety phone call
Study Endpoints • Primary: Average weekly number of angina episodes from weeks 2 -8 of treatment • Key Secondary: Average weekly number of SL NTG doses from weeks 2 -8 of treatment
Data Acquisition • Angina frequency and SL NTG use captured daily using electronic diary • Daily data transfer

Conclusions • Ranolazine was more effective than placebo in reducing angina frequency and SL NTG use in patients with type 2 diabetes, CAD and chronic angina • The therapeutic effectiveness of ranolazine was greater – In patients enrolled outside of Russia, Ukraine and Belarus – In those with higher baseline Hb. A 1 c • Future studies are needed to explore potential dual effects of ranolazine on angina and glucose control in patients with type 2 diabetes
