Dr. Chang completed postdoctoral research at Louis Stokes Cleveland Department of Veterans Affairs Medical Center. He has served as Director of R&D at JW Medical and also served as CEO/President of its subsidiary CorazonX, a company that developed ultrasound-based detection technology for coronary heart disease licensed from the University of Washington. Dr. Chang was formerly Director of R&D Emerging Markets of Medtronic Korea, overseeing multinational teams at Medtronic Innovation Center in Korea, Brazil and Turkey. After that, he served as the inaugural CEO/CTO of DeepQure, a medical device company developing a renal denervation system using laparoscopy.

During his tenure at Kalos, Dr. Chang has overseen the ongoing clinical development of Kalos’ DENEX device, Korea’s first medical device for treating hypertension using renal denervation. Kalos is currently conducting a randomized controlled trial of the DENEX device at 30 sites in Korea, including The Catholic University of Korea and Seoul St. Mary’s Hospital. Pivotal data readout from 148 subjects is anticipated in Q2 2023. In parallel, Kalos has initiated a second large, randomized trial at 20 sites in the European Union (EU), with the first patient already enrolled. Kalos plans to use the data from these trials to seek regulatory approval of the DENEX device in Korea, the EU, and the United States.
