About this study
Official title: A Phase 2, Randomized, Double-blind, Placebo-controlled, Parallel-group Exploratory Study to Access the Metabolic Effects of Ranolazine When Added to Ongoing Non-Insulin Antidiabetic Therapy in Subjects With Type 2 Diabetes Mellitus
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).

What is being measured
The primary outcome is the main question the study is designed to answer.
Change From Baseline in Glycosylated Hemoglobin (HbA1c) at Week 12
HbA1c is a blood test to measure blood sugar control over the prior 3-month period. The last observation carried forward (LOCF) method was used: the last observed post-baseline measurements prior to Week 12 carried forward for participants with no available Week 12 values. Participants were summarized according to the actual treatment received regardless of the allocated treatment.
Measured: Baseline to Week 12
Change From Baseline in 2-hour Postprandial Serum Glucose at Week 12 Following a Standardized Meal
2-hour postprandial serum glucose was defined as the average of serum glucose measurement at 120 minutes and 125 minutes following a standardized meal. The LOCF method was used. Participants were summarized according to the actual treatment received regardless of the allocated treatment.
Measured: Baseline to Week 12
Change From Baseline in Fasting Serum Glucose at Week 12
Serum glucose was measured following an overnight fast. The LOCF method was used. Participants were summarized according to the actual treatment received regardless of the allocated treatment.
Measured: Baseline to Week 12

A Phase 2 study testing Ranolazine in people with Diabetes Mellitus, Type 2, run by Gilead Sciences at 9 sites in United States.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 6 inclusion and 11 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 23 Sep 2013. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 9 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
Yes. Results are posted in the registry (first posted 23 Sep 2013). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Change From Baseline in Glycosylated Hemoglobin (HbA1c) at Week 12 (time frame: Baseline to Week 12). The study lists 3 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 23 Sep 2013.
