Tizona Therapeutics Announces Expansion of Phase 1b Clinical Trial to Evaluate TTX-080 in Combination with EGFR Inhibitor Cetuximab and Chemotherapy in Advanced Colorectal Cancer (GlobeNewswire) - "Tizona Therapeutics, Inc...today announced the initiation of two randomized arms within the ongoing Phase 1b clinical trial of TTX-080, a novel, first-in-class antibody targeting HLA-G. Patients with biomarker-defined metastatic colorectal cancer (mCRC) will be enrolled to receive either TTX-080 plus cetuximab and FOLFIRI or cetuximab and FOLFIRI alone in the second-line setting."

Results from phase 1a/1b analyses of TTX-080, a first in class HLA-G antagonist, in combination with cetuximab in patients (pts) with metastatic colorectal cancer and head and neck squamous cell carcinoma. (ASCO 2024) - P1 | "This Ph1a/1b study evaluated the safety and preliminary efficacy of TTX-080 alone or in combination with cetuximab (Cetx) or pembrolizumab (Pem) in multiple solid tumor cohorts (NCT04485013). TTX-080 is well tolerated alone and in combination with Cetx. TTX-080 + Cetx demonstrates promising activity in pts with HPV-Neg HNSCC and WT RAS/BRAF/Her2-Neg mCRC as manifested by the responses and PFS. These early findings warrant further investigation of TTX-080 + Cetx in a randomized controlled study against standard of care in mCRC and HNSCC."

[VIRTUAL] Targeting HLA-G-mediated immunosuppression with a first-in-class antagonist antibody (SITC 2020) - "Conclusions TTX-080 reverses HLA-G-mediated suppression of ILT2+ and ILT4+ immune cells that are found within the tumor microenvironment. Blockade of HLA-G using TTX-080 therefore has the potential to reverse broad immune suppression in patients with advanced solid tumors by reinvigorating CD8+ T cells, enhancing NK cytolytic activity, and increasing macrophage phagocytosis."
