In a significant study, Alloy Therapeutics researchers identified T Cell Receptor mimic (TCRm) antibodies with exceptional specificity for the Wilms Tumor 1 (WT1) antigen, ranked by National Cancer Institute as number one of the top targets for cancer immunotherapy. Identifying binders to WT-1/HLA-A2 is particularly challenging due to high homology with other peptides (M13L and PIGQ).
The Keyway TCRm Antibody Discovery Platform, powered by ATX-Gx™ transgenic mice, enabled the generation of highly specific antibodies with superior affinity and specificity compared to the three commercially available benchmark antibodies. This breakthrough has the potential to transform cancer treatment by enabling the development of TCRm-based therapies with enhanced efficacy and reduced off-target effects
