• good general health as determined by no acute illness and no clinically significant abnormal findings on medical history, clinical laboratory test results, vital signs, or physical examination
• platelet count of 150,000/uL to 400,000/uL and mean platelet volume (MPV) within the normal range

Subjects with stable CAD, defined as history of documented myocardial infarction (MI) or angina, or evidence of CAD derived from cardiac stress test, or imaging (calcium score [greater than 100 or abnormal for age], angiography, computerized tomography, or magnetic resonance image); absence of angina, or presence of angina with no change in frequency, duration, precipitating causes or ease of relief for at least 60 days, and no ECG or biomarker evidence of myocardial damage in past 60 days

• blood pressure control achieved with 4 or fewer anti-hypertensive medications
• on a stable regimen of aspirin at a dose of 81 to 325 mg/day

Main exclusion criteria (all subjects):

• history of prior stroke or clinically significant cardiovascular (e.g., unstable angina, New York Heart Association [NYHA] class II, II or IV heart failure), dermatologic, endocrine, gastrointestinal (GI), hematologic, infectious, metabolic, neurologic, psychologic, or pulmonary disorder or any other condition, including active cancer that in the opinion of the PI would jeopardize the safety of the subject or impact the validity of the study results
• history of upper or lower GI bleeding requiring intervention or treatment within 12 months of Screening or endoscopic evidence of active peptic ulcer disease within 6 months of Screening
• bleeding score > 3 on the International Society on Thrombosis and Haemostasis Bleeding Assessment Tool
• coagulation abnormality, bleeding disorder, or history of documented prior hemorrhagic or thrombotic stroke

• receiving or have received in the past 30 days an anticoagulant or fibrinolytic agent
• a cardiac pacemaker
• history of allergy to any of the ingredients in the RUC-4 or placebo formulation

Healthy Subjects only:

• medication known to have an impact on platelet function within 30 days of Screening.
• abnormally low response to arachidonic acid-induced platelet aggregation
• screening ECG abnormality that is interpreted by the PI to be clinically significant

Stable CAD subjects only:

• medication known to have an impact on platelet function, with the exception of aspirin, within 30 days of Screening.

  ->4 anti-hypertensive medications required to achieve blood pressure control

• incomplete inhibition of arachidonic acid-induced platelet aggregation
• acute changes on ECG
