Aulos Bioscience
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
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.
Andy Walker
Andy Walker is a chemical engineer turned biotech operator who co-founded GentiBio, a Cambridge-based company engineering regulatory T cells (EngTregs) to functionally cure autoimmune and autoinflammatory diseases. He started as the company's CTO, moved through President and COO, and became President and CEO in 2024. Before GentiBio he ran manufacturing for cell and protein therapeutics at Juno Therapeutics and led Jewel Biotherapeutics. He holds a PhD in chemical engineering from UC Berkeley and a BS from the University of Washington.
Zag Bio
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.
Orca Bio
Orca Bio is a late-stage biotechnology company in Menlo Park, California, building high-precision allogeneic cell therapies. Its proprietary single-cell sorting platform purifies donor immune and stem cells to engineer optimized therapeutic mixtures aimed at curing blood cancers and autoimmune diseases, with its lead candidate Orca-T currently under FDA priority review.
