The main objective of this study is to assess the safety and efficacy of Liposomal Alendronate in the treatment of de novo stenotic lesions in native coronary arteries in a population undergoing PCI with implantation of a bare metal stent.

Study hypothesis: Liposomal Alendronate will reduce in-stent restenosis as compared to placebo.

Detailed Description:

This is a Phase II dose-finding, randomized, multi-center, prospective, double blind clinical study. Subjects undergoing percutaneous coronary intervention (PCI) with the Presillion™ CoCr bare metal stent will be randomized into three groups and administered (in a single dose intravenously (IV) through a peripheral venous catheter) either: low dose Liposomal Alendronate of 0.001 mg, high dose Liposomal Alendronate of 0.01 mg, or placebo (IV saline infusion) on a 1:1:1 basis.

All subjects will undergo angiographic follow-up at 6 months and 110 subjects enrolled from pre-specified sites will undergo intravascular ultrasound (IVUS) at baseline and follow-up at 6 months.

Angiographic Exclusion Criteria

  1. Unprotected left main coronary artery disease (obstruction greater than 50% in the left main coronary artery that is not protected by at least one non-obstructed bypass graft to the LAD or Circumflex artery or a branch thereof).
  2. Any previous stent placement within 15 mm (proximal or distal) of the target lesion(s).
  3. Target vessel exhibiting lesions with greater than 60% diameter stenosis outside of a range of 5 mm proximal and distal to the target lesion(s) based on visual estimate or on-line QCA.
  4. Target lesion(s) exhibiting an intraluminal thrombus (occupying >50% of the true lumen diameter) at any time.
  5. Lesion location that is aorto-ostial or within 5 mm of the origin of the left anterior descending (LAD) or left circumflex (LCX).
  6. The target lesion(s) requires treatment with a device other than PTCA prior to stent placement (such as, but not limited to, directional coronary atherectomy, excimer laser, rotational atherectomy, etc.).
  7. Target lesion(s) with side branches > 2.0mm in diameter.
  8. Target lesion(s) involving a bifurcation (either stenosis of both main vessel and major branch or stenosis of just major branch).
  9. Target lesion(s) with severe calcification.
