Benefits of VH(R) IVUS in Drug Development

SAN DIEGO, Calif., Sept. 2 /PRNewswire-FirstCall/ -- Volcano Corporation (Nasdaq: VOLC) [ESC Booth # A2-D403], a leading manufacturer of intravascular ultrasound (IVUS) and functional measurement (FM) technology, announced today the use of its VH(R) IVUS (Virtual Histology IVUS) in GlaxoSmithKline's IBIS-2 trial (Integrated Biomarker and Imaging Study). In the study, Volcano's VH(R) IVUS technology demonstrated and quantified compositional changes in atherosclerotic plaque that occurred over time. In IBIS-2, VH(R) IVUS showed compositional changes in the placebo group that suggest continued progression of necrotic core despite standard of care therapy. Use of the novel Lp-PLA2 inhibitor, darapladib, plus standard of care therapy prevented this progression. VH(R) IVUS is a catheter-based technology that creates colorized tissue maps of plaque composition in real-time.

Despite remarkable advances in diagnosis and therapy, atherosclerotic cardiovascular disease (CVD) is the number one killer of men and women in the Western world. Principal manifestations of atherosclerotic cardiovascular disease are heart disease and stroke. Atherosclerosis is the underlying mechanism for coronary artery disease, ischemic strokes, and peripheral vascular disease. Although a number of factors contribute to CVD, elevated plasma levels of Lp-PLA2 (lipoprotein-associated phospholipase A2) are associated with an increased risk.

"The results of IBIS-2 indicated that many coronary vessels with mild angiographic disease have large atherosclerotic plaques, which can be identified by VH(R) IVUS. The ability to character
