LUND, SE / ACCESS Newswire / April 23, 2025 / Alligator Bioscience (Nasdaq Stockholm:ATORX) today announces that Shanghai Henlius Biotech, Inc. ("Henlius") has initiated a Phase 2 clinical trial with HLX22, an anti-HER2 monoclonal antibody originally developed by Alligator's subsidiary, Atlas Therapeutics.
