Safety of KAI-9803 for Injection With Angioplasty Following Heart Attack
The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government.

Restoring blood flow to coronary arteries as quickly as possible is the best way to reduce the damage to the muscle that occurs with a heart attack. However, up to 25-50% of patients who have angioplasty may have ongoing damage to the heart muscle when the blockage is opened and blood flow is restored. Complications which may result from this ongoing damage include a larger area of damaged muscle in the heart, enlargement of the heart, an increased risk of death, and an increased risk of heart failure. Some of the ongoing damage may involve increased levels of the protein kinase C (PKC) enzyme. KAI-9803 is a selective inhibitor of delta PKC. In this study, delta PKC is used with angioplasty and other standard procedures to restore blood flow after a heart attack. This study is designed to evaluate safety of different amounts of KAI-9803 when used in treating heart attack patients undergoing angioplasty. We will also try to evaluate whether KAI-9803 can reduce the amount of heart muscle damage and the complications that may occur in these patients.

Sexes Eligible for Study:
Accepts Healthy Volunteers:
Symptoms of cardiac ischemia at rest or with increasing frequency (angina or angina equivalent), with episodes lasting for at least 30 minutes within 6 hours of presentation
Persistent ST-segment elevation of ≥ 0.2 mV in at least 2 contiguous precordial leads indicative of anterior Myocardial Infarction (MI) location (leads V1-V4)
At least 18 years old

Culprit lesion suitable for primary percutaneous coronary intervention (PCI)
Any left bundle branch block (new or old), intraventricular conduction defect, or paced rhythm that would obscure the diagnosis of acute anterior ST Elevation Myocardial Infarction (STEMI)
Any prior documented myocardial infarction (MI), including old Q waves documented on prior ECGs or a clinical history of definite MI
Any prior coronary artery bypass grafting (CABG)
Cardiogenic shock at initial hospital presentation, consisting of persistent hypotension (systolic blood pressure < 90 mm Hg for > 20 minutes) and signs of end-organ dysfunction (oliguria, altered mental status, poor peripheral perfusion, and lactic acidosis)
TIMI grade 2 or 3 flow in the left anterior descending artery documented on the initial diagnostic angiogram
Culprit lesion in the left anterior descending artery that is not suitable for primary PCI
Treatment with intravenous fibrinolytic therapy (i.e. alteplase, reteplase, tenecteplase, or streptokinase) within the 24 hours before presentation
Know baseline creatinine > 2.5 mg/dL without renal dialysis/renal replacement therapy within the 30 days before presentation
Inability to comply with study procedures, inability to undergo cardiac catheterization or primary percutaneous coronary intervention (PCI)
Participation in a study of experimental therapy (drug or device) within 30 days of presentation, or prior participation in this study
