Hillstar Bio™ is shaping a new era in autoimmune disease treatment through precision immunology. We selectively target and deplete 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, our targeted approach addresses specific disease mechanisms by eliminating pathogenic cells, reducing the risks associated with chronic broad immunosuppression while potentially delivering deeper, more durable responses with less frequent dosing compared to existing therapies. We combine scientific expertise in antibody engineering with a disciplined approach, building upon validated modalities and disease-specific genetic markers to de-risk development while identifying patient populations most likely to benefit from our therapies, moving beyond the one-size-fits-all approach of current autoimmune treatments.
