Brief summary: This trial will treat patients with a new chemotherapeutic medicine who have undergone a successful and uncomplicated de novo stent placement in up to two native coronary arteries. The purpose of the trial is to determine the appropriate dose of the new medicine for future trials and to evaluate the incidence of treatment-emergent adverse events and serious adverse events.

Detailed description: See inclusion/exclusion criteria.

* Angiographic evidence of thrombus post-stenting
* Prior stent within 5 mm of target lesion
* Left ventricular ejection fraction less than 30%
* Greater than 50% stenosis proximal or distal to target lesion
* Malposition, dissection, or unmasking of a significant narrowing in the inflow or outflow area of the implanted stent
* Patient has received a drug coated stent as part of this procedure

Exclusion Criteria Related to ABI-007:

* Absolute neutrophil count is less than 1500 cells/mm3
* Platelet count is less than 100,000 cells/mm3
