7. Females who are nursing, pregnant, or intend to become pregnant during the time of the study, or females of childbearing potential who have a positive pregnancy test during screening evaluation. Women of child-bearing potential must also use a reliable method of birth control during the study and for 1 month following completion of therapy. A reliable method for this study is defined as one of the following: oral or injectable contraceptives, intrauterine device (IUD), contraceptive implants, tubal ligation,
hysterectomy, a double barrier method (diaphragm with spermicidal foam or jelly, or a condom).
8. Subjects who have a history of alcohol or drug abuse within 1 year of study entry
9. Subjects living too far from participating center or unable to
return for follow-up visits
10. Subjects who in the opinion of the Investigator are a poor
medical or psychiatric risk for therapy with an investigational drug, are unreliable, or have an incomplete understanding of the study which may affect their ability to take drugs as prescribed or comply with instructions
11. Known human immunodeficiency virus (HIV), Hepatitis B virus (HBV), Hepatitis C virus (HCV), or tuberculosis infection
12. Acute bacterial, fungal or viral infection
13. Subjects currently taking drugs that are potent inhibitors of cytochrome P450 unless they can be withdrawn
14. Subjects with New York Heart Association (NYHA) Class III or IV heart failure, or if known, left ventricular ejection fraction (LVEF) 30%
15. Subjects with moderate or severe aortic stenosis, aortic regurgitation, mitral stenosis or mitral regurgitation
16. Ventricular arrhythmias requiring chronic drug treatment or
implantable cardioverter-defibrillator (ICD)
17. Subjects with no stenosis or stenosis 50% on angiography, if known
18. Subjects with a pacemaker or persistent left bundle branch block (LBBB)
19. Fasting triglyceride levels of more than or equal to 400mg/dL (4.5 mmol/L)
20. Subjects who have a history of statin intolerance or a significant myopathy or rhabdomyolysis with any lipidaltering drugs
21. Subjects currently treated with the maximum labeled dose of a statin and not at LDL-C target for their level of risk as defined by NCEP ATP
Method of Generating Random Sequence
Computer generated randomization
Method of Concealment
Participant and Outcome Assessor Blinded
To determine whether 16 weeks of
treatment with A-002 plus atorvastatin and standard of care is superior to placebo plus atorvastatin and standard of care for reducing the hazard of the first occurrence of the combined endpoint of cardiovascular death, non fatal myocardial infarction, non-fatal stroke, or documented unstable angina with objective evidence of ischemia requiring hospitalization.
To determine whether A-002 plus atorvastatin and standard of care is superior to placebo plus atorvastatin and standard of care for reducing the occurrence of the hazard of the combined endpoint of all-cause mortality, non-fatal myocardial infarction, non-fatal stroke, or documented unstable angina with objective evidence of ischemia requiring hospitalization, or multiple occurrences of the non-fatal components of the composite primary endpoint.
Target Sample Size

This is a double-blind, randomized, parallel group, placebo controlled study in subjects presenting with an ACS. Up to 6500 subjects will be randomized to receive either A-002 500 mg once daily (QD) or placebo tablets in addition to atorvastatin QD and standard of care. Treatment will be 16 weeks in duration. The dose of atorvastatin shall be adjusted after 8 weeks if LDL-C of subject is more than or equal to 100 mg/dL, but otherwise must remain stable throughout the16-week duration of study. The survival status for all enrolled subjects will be ascertained 6 months after they complete the study. Randomization must occur within less than or equal to 96 hours of hospitalization for the index ACS event, or if already hospitalized, within 96 hours of index event diagnosis. Follow-up visits occur at 1, 2, 4, 6, 24, 48, 72 and 96 and Weeks 1, 2, 4, 8 and 16. Randomization will be stratified by the presence or absence of lipid-altering therapy prior to the index event as well as the type of index event (admission diagnosis of unstable angina, NSTEMI or STEMI). The number of subjects who undergo PCI following the index event and prior to randomization will be limited to no more than 55% of the total study population.
