|
E.2.2 | Secondary objectives of the trial |
The following secondary objectives will be independently assessed in the anterior and inferior STEMI cohorts: Assess the effect of KAI-9803 compared with placebo on ST recovery area-under-the-curve as measured by continuous 12-lead ECG monitoring Assess the effect of KAI-9803 compared with placebo on recurrent ischemia as measured by continuous 12-lead ECG monitoring Assess the effect of KAI-9803 on the incidence of the composite of cardiovascular death, heart failure, or serious ventricular arrhythmias Assess the effect of KAI-9803 on other markers of infarct size including: total and estimated peak CK, total and estimated peak troponin I and estimated peak CK-MB undergoing primary PCI during the index hospitalization To assess the effect of KAI-9803 compared with placebo on serum NT-pro-B-type natriuretic peptide levels Assess the effect of KAI-9803 compared with placebo on the incidence of contrast-induced nephropathy Assess the safety and tolerability KAI-9803 |

E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
a. Subject understands the study procedures and agrees to participate in the study by giving written informed consent. b. Subject is at least 18 years old. c. Women of childbearing potential (WOCBP) must have a negative urine or serum pregnancy test confirmed before randomization. WOCBP must be willing to use an acceptable method of contraception to avoid pregnancy for 10 days after randomization. WOCBP is defined as any female who has experienced menarche and who has not undergone successful surgical sterilization (hysterectomy, bilateral tubal ligation, or bilateral oophorectomy) or is not postmenopausal (defined as amenorrhea ≥12 consecutive months; or women on hormone replacement therapy [HRT] with documented serum follicle stimulating hormone [FSH] level > 35 mIU/mL). Women who are using oral contraceptives, other hormonal contraceptives (vaginal products, skin patches, or implanted or injectable products), or mechanical products such as an intrauterine device or barrier methods (diaphragm, condoms, spermicides) to prevent pregnancy, or are practicing abstinence or where their partner is sterile (eg, vasectomy) should be considered to be of childbearing potential. d. Subject presents with acute STEMI and has a planned emergent primary PCI procedure. e. Subject must have a minimum of 30 minutes of continuous symptoms of cardiac ischemia and present to the primary PCI facility within 6 hours of symptom onset. f. Subject must have persistent ST elevation of: ≥ 2 mm in at least two contiguous precordial leads indicative of anterior MI location (leads V1-V4; anterior STEMI cohort) or persistent ST elevation of ≥ 2 mm in two inferior leads (leads II, III or aVF) coupled with ST depression in two contiguous anterior leads for a total of at least 8 mm (inferior STEMI cohort). |
|
E.4 | Principal exclusion criteria |
a.Intraventricular conduction defect (including left bundle branch block), or paced rhythm that would obscure the diagnosis of acute STEMI. b. Persistent systolic blood pressure <90 mm Hg (i.e., unresponsive to IV fluids). c. Currently receiving vasopressors (e.g., norepinephrine) or inotropes (e.g., dobutamine). d. History of end stage renal disease requiring hemodialysis or peritoneal dialysis. e. Known history of severe hepatic dysfunction (e.g., cirrhosis, ascites) or clinically jaundiced at randomization. f. Any prior coronary artery bypass grafting (CABG). g. Treatment with intravenous fibrinolytic therapy (e.g., alteplase, reteplase, tenecteplase, and streptokinase) within the 72 hours prior to presentation. h. Women who are pregnant or breast-feeding. i. Inability to comply with study procedures, including inability to undergo cardiac catheterization or primary PCI. j. Serious concurrent medical condition (e.g. malignancy) likely to result in death during next 12 months. k. Participation in a study of experimental therapy (drug or device) within 30 days of presentation. l. Clinical suspicion of non-thrombotic (e.g., pericarditis, vasospasm, illicit drug use) cause for ST-segment elevation as determined by the Investigator. m. Prior participation in this study. n. Prisoners or subjects who are involuntarily incarcerated. o. Subjects who are compulsorily detained for the treatment of either psychiatric or physical (e.g., infectious disease) illness. |
