More than two decades after founding Berlin Heart, the company's former CEO, Johannes Müller – a doctor, researcher and inventor behind that company's pioneering ventricular assist device – is leading a new company, Berlin Cures Holding AG, to attack a root cause of a common type of heart failure with a new DNA aptamer-based compound, BC-007. It enters phase II testing this summer. The trial is expected to read out by the middle of 2020.
