298380 Company Profile

ABL Bio develops bispecific antibodies and a shuttle technology meant to carry drugs across the blood-brain barrier, the obstacle that has defeated many treatments for brain disease. It licensed that platform to GSK and has partnered with Sanofi on neurodegenerative programs, so much of its value sits in milestones owed by large Western drugmakers. It runs its own oncology pipeline alongside those deals. US investors can assess it partly through the development timelines its partners disclose.
