In Europe and North America, an estimated 27 million individuals are affected with peripheral artery disease (PAD), which is caused by the accumulation of plaque in peripheral arteries (commonly the pelvis or leg) reducing blood flow. Left untreated, PAD can lead to severe pain, immobility, non-healing wounds and eventually limb amputation. With risk factors such as diabetes and obesity on the rise, the prevalence of PAD is growing at double-digit rates.
CBSET is committed to the development of novel experimental and computational models for defining the barrier effects of tissue components on drugs of interest and evaluating novel endovascular therapies. CBSET's scientists have published a range of data and analyses on PAD treatments and related therapies.
At CRT19, CBSET’s Director of Research and Innovation, Rami Tzafriri, PhD, was interviewed by Michael Mooney, MD, of Minneapolis Heart Institute, Abbott Northwestern hospital about CBSET’s PAD preclinical study: Enhanced Plaque Modification of Cadaveric Human Calcified Peripheral Arteries Treated with a Vessel Preparation System. In this interview, Rami discusses CBSET’s human cadaver model assessment of a vessel preparation system and the attributes of this particular technology that suggest it might be conducive to enhancing drug absorption.
