The purpose of this study is to determine: (1) the safety and pharmacokinetics of APL180 administered as a single intravenous infusion in healthy volunteers, and (2) the safety, pharmacokinetics and pharmacodynamics of single and multiple daily intravenous infusions of APL018 in patients with CHD

• Drug: APL180
• Drug: Placebo

Inclusion Criteria:

• Male and female healthy volunteers (ages 18-55 years) and patients with CHD (ages 18 to 75 years) on stable statin therapy for at least 8 weeks, with normal liver and kidney function.
• Women who are post-menopausal, surgically sterile, or practicing effective contraception. Additional birth control details to be provided at screening.
• Body mass index (BMI) must be within the range of 20 to 35 for CHD patients or CHD equivalents.
• Clinical CHD:
• Myocardial infarction (MI), angina, revascularization (e.g. CABG, stent) at least 6 months prior to inclusion
• CHD equivalents:
• symptomatic carotid artery disease (e.g. transient ischemic attack or stroke of carotid origin) or peripheral artery disease or abdominal aortic aneurysm or Diabetes Mellitus (HbA1c ≤9)
• 20% 10 year risk of CHD (Framingham point score: ≥16 (men), ≥23 (women))
• Other clinical forms of atherosclerotic disease including >50 percent stenosis on angiography or ultrasound
• Male subjects, when sexually active, using one form of highly effective contraception (e.g. condom)

Exclusion Criteria for both healthy volunteers and patients:

• Smokers (use of tobacco products in the previous 3 months). Smokers who report cigarette use of more then 10 cigarette per day or have a urinary cotinine level greater then 500 ng/ml.
• Pregnancy.
• Use of any prescription drugs within four (4) weeks prior dosing, or over-the-counter (OTC) medication (vitamins, herbal supplements, dietary supplements) within two (2) weeks prior to dosing. Significant illness within two weeks prior to dosing.
• Significant illness within two weeks prior to dosing.
• A past medical history of clinically significant ECG abnormalities or a family history of a prolonged QT-interval syndrome.
• History of clinically significant drug allergy or history of atopic allergy (asthma, urticaria, eczematous dermatitis). A known hypersensitivity to the study drug or drugs similar to the study drug or any allergic reaction to prior receipt of protein therapies or vaccines.
• Presence of NYHA Class III or IV CHF or unstable angina pectoris.
• MI or within angioplasty (including stenting), acute coronary syndrome (ACS), unstable angina or arterial embolic disease within 6 months prior to dosing.
• Use of certain medications prohibited by the protocol.
• Uncontrolled diabetes (HbA1c > 9).
• Uncontrolled hypertension (Systolic BP >160 mm Hg and/or Diastolic BP >100 mmHg on two consecutive measurements).
• Liver or kidney disease confirmed by abnormal lab values or function.
• Serum creatine kinase CK (CPK) total > 2x.
• CHD equivalent patients with a history of early positive exercise stress test.
