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.

Oncology: ARCStim Platform

Next-gen T Cell Engagers to Transform Solid Tumor Therapy

Tumor Specificity

Precision targeting at the epitope level for tumor specificity

Conditional Activation

Tumor-dependent activation for improved therapeutic index

Signal 2 Costimulation

Amplifying T cell activation for deep and durable responses

I&I: ARCTag Platform

Tissue-specific Suppression of Immune Cells

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.

We continue to expand a compelling pipeline with next-generation solid tumor and I&I multispecific programs.
