BEIJING – Chinese transcatheter heart valve developer Venus Medtech (Hangzhou) Inc. on Tuesday saw its share prices jump around 20% on its debut on the Hong Kong Stock Exchange (HKEX), an excellent start for a prerevenue med-tech IPO.

Ann Arbor, Mich.-based startup Endra Life Sciences Inc. started out focused on a photoacoustic imaging tool for mice in the lab, but in recent years it has shifted gears. Now, it aims to secure the go-ahead next year from European and U.S. regulators to launch a thermo-acoustic enhanced ultrasound system designed to quantitatively assess liver fat, known as TAEUS.

With a 349% increase in stock price since its June debut on U.S. markets, Boston-based Karuna Therapeutics Inc. secures the title of best IPO performer so far in 2019. The stock skyrocketed in November following positive top-line phase II data of Karxt in acute psychosis in patients with schizophrenia, providing a potential read-through to larger indications such as Alzheimer’s disease and pain.
