HONG KONG – Chinese biotech firm Shanghai Henlius Biotech Inc. is taking its PD-L1 antibody known as HLX-20 to Australia to enter a phase I trial for the treatment of advanced solid tumors. The approval from the Australian authorities came six months after Henlius filed the investigational new drug (IND) application for HLX-20 to the China Drug Administration (CDA), and the trial will be the company's first in Australia.
