PERTH, Australia – Perth-based regenerative medicine company Orthocell Ltd. saw its shares rise 27% on the heels of its first U.S. approval for its collagen medical device for dental guided bone and soft tissue regeneration applications. “It’s an important milestone for us, and one that came quicker than I was expecting it to come,” Orthocell CEO Paul Anderson told BioWorld. The company submitted its 510(k) application to the FDA in May, and he was expecting approval by the middle of 2021.
