| MedDRA Classification | 
| E.1.3 | Condition being studied is a rare disease | No | 
| E.2 Objective of the trial | 
| E.2.1 | Main objective of the trial | 
| To test the hypothesis that administration of GAP-486 is effective in decreasing the number of non-life-threatening ventricular arrhythmias in subjects who have acute coronary syndrome (unstable angina, ST segment elevated myocardial infarction [STEMI] or myocardial infarction without ST elevation [NSTEMI] subjects). |  | 
| E.2.2 | Secondary objectives of the trial | 
| To assess safety and tolerability in subjects with acute coronary syndrome.To assess the dose-range and identify potentially effective doses for phase 3 studies. |  | 
| E.2.3 | Trial contains a sub-study | Information not present in EudraCT | 
| E.3 | Principal inclusion criteria | 
| - Men and surgically sterile or postmenopausal women 18 through 95 years of age. Postmenauposal women: at least 12 months of spontaneous amenorrhea or at least 6 months of spontaneous amenorrhea with serum FSH level > 40mIU/mL or at least 6 weeks postsurgical bilateral oophrectomy (with or without hysterectomy). - Subjects must fulfill clinical criteria for an acute ischemic event.
 - Subjects must have experienced at least 1 episode of non-sustained ventricular tachycardia (NSVT) or a self-terminating episode of sustained ventricular tachycardia before the 3-hour baseline Holter monitor is started.
 - Subjects will have test article within 36 hours from the episode of ischemia.
 |  | 
| E.4 | Principal exclusion criteria | 
| -Subjects for whom percutaneous coronary intervention (PCI), thrombolytics, or CABG is anticipated during the 24-hour on-therapy phase of the study.  However, revascularization procedures must not be delayed or withheld for the purposes of qualifying for or participating in the study. -Subjects who have had previous PCI, treatment with thrombolytics, CABG, or other cardiac surgeries within 24 hours prior to screening.
 -Subjects for whom (at the time of enrollment) cardiac angiography or stress testing is planned during the 24-hour on-therapy phase of the study.
 -Any antiarrhythmics (with the exception of beta blockers) given within 5 half-lives of the start of the 24-hour on-therapy phase of the study.
 -Subjects with cardiogenic shock
 -Subjects with acute pulmonary edema who do not respond immediately to diuretic treatment.
 -Documented history of torsade de pointes.
 -Known congenital long QT syndrome.
 -QTc   > 0.50 second at screening.
 -Bradycardia < 40 beats per minute for > 1 minute or sinus pauses > 3 seconds while awake which occur anytime during the 30 minutes prior to test article administration.
 -Subjects with New York Heart Association (NYHA) Class IV Congestive Heart Failure (CHF).
 -Presence of or immediate need for continuous ventricular demand pacemaker.
 -Known significant hepatic dysfunction unrelated to the acute ischemic event or renal dysfunction
 -Subjects with hypokalemia at the time of Holter monitor placement.
 -Subjects with new onset atrial fibrillation of < 1 month duration or subjects with unknown duration of atrial fibrillation are excluded.  However, if a subject has a negative transesophageal echo or is known to have chronic atrial fibrillation > 1 month and has been receiving anticoagulants for > 1 month, and meets all the inclusion/exclusion criteria, they are eligible to participate in the study.
 -Subjects with Wolff-Parkinson-White syndrome
 -Current use of investigational device or use of investigational drug within 30 days before entry into the study.
 -Subject who previously received test article in this study.

| E.5 End points | 
| E.5.1 | Primary end point(s) | 
| Total number of ventricular arrhythmia beats (the sum of ventricular arrhythmia beats from premature ventricular contractions, couplets, and individual beats in each NSVT and sustained VT episode [see section 6.0 of the Protocol for definitions]) recorded by Holter monitoring during the 24-hour on-therapy phase. |  |
