About
Hillstar Bio is shaping a new era in autoimmune disease treatment through precision immunology. The company selectively targets and depletes pathogenic immune cells while sparing healthy ones, offering the potential for durable relief via an immune reset for patients with autoimmune conditions. Unlike traditional therapies that broadly suppress the immune system, its targeted approach addresses specific disease mechanisms by eliminating pathogenic cells and reducing the risks of chronic immunosuppression. Lead program HSB-101 depletes TRBV9+ T cells in axial spondyloarthritis and related HLA-B27-mediated conditions, with Phase 1 anticipated in 2026.
Summary
Hillstar Bio is a Biotech company. It has raised $67.0M in total across 1 round, most recently a $67.0M Series A round in Mar 2025. Investors include Novo Holdings A/S and Frazier Life Sciences.
