Translating scientific breakthroughs into first-in-class treatments
Novel insights into human biology define our development programs that target cancer
Pipeline Overview
Our oncology pipeline is focused on restoring and bolstering immune responses. Tizona is enrolling patients in two randomized arms within the ongoing Phase 1b clinical trial (NCT04485013) to evaluate either TTX-080 plus cetuximab and FOLFIRI or cetuximab and FOLFIRI alone in biomarker-defined metastatic colorectal cancer.


HLA-G Suppresses Both Adaptive & Innate Immune Activity

HLA-G is normally expressed at the maternal-fetal interface and certain sites of immune privilege. In cancer, its expression is used as an immune evasion strategy. HLA-G mediates its potent suppression through binding to receptors found on tumor infiltrating immune cells.
