Aulos Bioscience is a Larkspur, California, clinical-stage immuno-oncology company using artificial intelligence to design antibody therapeutics that unlock the anti-cancer power of interleukin-2 (IL-2). Its lead candidate, imneskibart (AU-007) - described as the first AI-designed human monoclonal antibody to enter human clinical trials - redirects IL-2 away from immune-suppressing regulatory T cells and toward immune-activating effector T cells and NK cells, aiming to treat solid tumors such as melanoma and non-small cell lung cancer while avoiding the toxicity that has limited earlier IL-2 therapies.
GentiBio is a clinical-stage biotechnology company in Cambridge, Massachusetts building engineered regulatory T cell (EngTreg) therapies designed to restore immune tolerance and durably treat autoimmune, autoinflammatory, alloimmune, and allergic diseases. Spun out of research from Seattle Children's, Benaroya Research Institute, and MIGAL Galilee Research Institute, the company combines gene editing of FOXP3 with a modular Treg engineering and manufacturing platform. Its lead program, GNTI-122, is an autologous antigen-specific Treg therapy for recently diagnosed type 1 diabetes now in a Phase 1 trial (POLARIS). GentiBio has raised roughly $177M and signed a partnership with Bristol Myers Squibb worth up to $1.9B in potential milestones.
Zag Bio is a Cambridge, Massachusetts biotechnology startup pioneering thymus-targeted medicines for autoimmune disease. Founded and incubated by Polaris Partners and launched in October 2025 with an $80M Series A, the company designs bifunctional antibodies that ferry self-antigens directly into the thymus - the organ that trains immune cells - to re-teach the body to tolerate its own tissue rather than attack it. Its lead program, ZAG-101, aims to prevent or delay Type 1 diabetes by inducing durable, antigen-specific central tolerance instead of broad immunosuppression.
