FOCUS ON PERIPHERAL ARTERY DISEASE (PAD)
CBSET's approach to the study of novel PAD therapies
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.

CBSET, training the next generation of PAD therapy researchers:
CBSET is leveraging its expertise in PAD-related animal computational models to support its medical device industry sponsors and to train the next generation of physicians and scientist working in this field. Both of these missions have been recognized and are partially supported by DECODE, a European Union Horizon 2020 / Marie Curie training grant.
The project leading to this application has received funding from the European Union’s Horizon 2020 research and innovation programme under the Marie Skłodowska-Curie grant agreement No 956470.
