What is being separated
First Tracks Bio holds AnaptysBio's clinical-stage antibody pipeline in autoimmune and inflammatory disease — ANB033, rosnilimab and ANB101 — and launched with about $180 million of cash and a two-year runway. AnaptysBio keeps the financial collaborations on Jemperli with GSK and imsidolimab with Vanda, running with minimal staff to protect and return that value to shareholders.
Stated rationaleAnaptysBio said in September 2025 that separating its biopharma operations from its royalty assets would let each be valued on its own terms, with a focused strategy and a clear path forward.
