Current autoimmune treatments are largely systemic, which raise the risk of infection and malignancy, and limit combination regimes. Third Arc Bio addresses the shortcomings of current autoimmune treatments with our ARCTag Platform, which localizes immune modulating molecules to the site of disease.
Two Innovative Platforms: Solid Tumors and Inflammatory & Immunology (I&I)
By tailoring approaches for each disease mechanism, Third Arc Bio develops immune cell-engaging antibodies that modulate T cell activity at the site of disease, to transform the treatment paradigm for both oncology and I&I diseases.
