AbCellera Presents Data on Applications of T-Cell Engager Platform at SITC 2024

AbCellera (Nasdaq: ABCL) today announced new data on its T-cell engager (TCE) platform, to be presented as a poster at the Society for Immunotherapy of Cancer (SITC) 39th Annual Meeting at the George R. Brown Convention Center in Houston, Texas.

AbCellera’s presentation, which is available for viewing here , describes:

Strategies to address key challenges in TCE development:

• CD3-binding antibodies to widen the therapeutic window by generating TCEs with potent tumor-cell killing and optimal cytokine release
• Molecules to enhance efficacy for solid tumor indications by increasing T-cell activation and proliferation through costimulation of CD28 and 4-1BB

Application of the platform to two of AbCellera’s TCE programs:

• Preclinical characterization of TCEs against solid tumor targets B7-H4 and PSMA show tumor-cell killing and cytokine release profiles that are differentiated from clinical benchmarks

About AbCellera’s T-Cell Engager Platform

CD3 T-cell engagers have the potential to be a cornerstone of cancer treatment. They guide the immune system to find and eliminate cancer cells by binding tumor targets and the CD3 protein on cancer-killing T cells at the same time. However, the development of T-cell engagers has been limited due to challenges with efficacy and safety. To address these challenges, AbCellera developed a T-cell engager platform that includes novel CD3-binding antibodies to expand the therapeutic window for this modality, costimulatory building blocks to enhance efficacy for difficult-to-treat cancers, and discovery capabilities to broaden the range of T-cell engagers to complex tumor targets. AbCellera is leveraging its platform to unlock the full potential of this modality and bring potential new cancer medicines to patients.
