CDR-Life Unveils Results on T-Cell Engagers Targeting Hard-to-Treat Solid Tumors at AACR 2024
Identifying a TCE against the KK-LC-1 peptide on HLA-A*01 will provide an option for patients that do not benefit from the more common HLA-A*02 targeting therapeutics currently in development.
- Identifying a TCE against the KK-LC-1 peptide on HLA-A*01 will provide an option for patients that do not benefit from the more common HLA-A*02 targeting therapeutics currently in development.
- However, high levels of similar off-target peptides presented in healthy tissues make targeting the KK-LC-1/HLA-A*01 challenging.
- CDR-Life’s data gathered on pMHC TCE antibodies with high specificity towards HLA-A*01 restricted KK-LC-1 epitopes demonstrate the antibodies’ promising anti-tumor activity and specificity for KK-LC-1/HLA-A*01 positive tumors.
- In vitro studies showed significantly higher TCE-dependent T-cell activation towards cells presenting the target peptide compared to the risk peptides.
