Does Ranolazine Decrease Biomarkers of Myocardial Damage in Diabetics

May 16, 2017 updated by: Todd C. Villines, Walter Reed National Military Medical Center

Does Ranolazine Decrease Biomarkers That Indicate Evidence of Myocardial Damage in Diabetics With Stable Ischemic Heart Disease? A Double-blinded, Randomized, Placebo Controlled Trial

The purpose of this investigation is to compare subjects at high risk for silent myocardial ischemia in the placebo group to subjects at high risk for silent myocardial ischemia in the ranolazine group to determine if ranolazine can be used as a treatment to decrease silent myocardial ischemia (SMI). Subjects at high risk for silent myocardial ischemia are defined in this protocol as diabetics with stable ischemic heart disease. This study will look at the impact ranolazine treatment has on biomarkers that have been shown to be highly associated with increased risk of morbidity and mortality in relation to SMI. If the hypothesis is correct, further studies can be conducted to determine if treatment with ranolazine has impact on long-term outcomes such as hospitalizations, myocardial infarction, congestive heart failure or sudden cardiac death.

Interventional

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.
