Primary outcomePrimary: Change From Baseline in Glycosylated Hemoglobin (HbA1c) at Week 12 — -0.61; -0.08 percent of HbA1c in blood — p=0.010

Summary

This study enrolled participants with inadequately controlled type 2 diabetes mellitus (T2DM) despite non-insulin antidiabetic therapy in addition to diet and exercise, and would have benefited from additional control of blood glucose levels. The study assessed the metabolic effects of ranolazine, including its effect in lowering glycosylated hemoglobin A1c (HbA1c), and lowering glucose while fasting, and following a meal (postprandial). Participants were randomized in a 1:1 ratio to receive ranolazine or placebo, and were stratified by HbA1c ≤ 7.5% or > 7.5%. Enrollment was to include no more than two-thirds of participants with baseline HbA1c ≤ 7.5%. Other than glucose values, efficacy endpoint results remained blinded during the study; for safety purposes, the investigator was to be alerted of severe hyperglycemia or hypoglycemia. Participants were instructed to maintain logs of their physical activity/exercise (Subject Activity Assessment) and study drug dosing (Dosing Log).

Change in non-insulin antidiabetic therapy in addition to diet and exercise < 2 months prior to screening
Any clinically significant cardiovascular event < 2 months prior to screening
Clinically significant, inadequately controlled or unstable hypertension
Hospitalization < 2 months prior to screening
Major surgery < 3 months prior to screening
