This platform is designed to generate soluble TCRs with ultra-high affinity, enabling the recognition of intracellular antigens that are typically inaccessible to traditional antibody-based therapies. This approach allows the redirection of T cells via an anti-CD3 immune-activating effector function, thereby ensuring that even tumors with low levels of immune cell infiltration (so-called “immune cold” tumors) can be effectively targeted.

- TCR Engineering & Affinity Enhancement:
The company utilizes advanced molecular engineering techniques to enhance the affinity and specificity of TCRs. This includes affinity enhancement and optimization of the TCR binding domains, ensuring that the engineered molecules can robustly bind to peptide-HLA complexes and trigger potent T cell responses. In doing so, Immunocore minimizes off-target effects while maximizing clinical efficacy.

- Bispecific Molecule Design:
Immunocore’s portfolio includes not only ImmTAX but also other bispecific approaches such as ImmTAC molecules. These are engineered to create a bridge between the tumor cells and the patient’s immune system, thereby recruiting cytotoxic T cells to the tumor site. Their design incorporates structural and functional features that help overcome challenges faced by conventional immunotherapies, such as inadequate T cell infiltration and tumor heterogeneity.

- Preclinical Safety and Efficacy Models:
Another vital technological advancement is their in vitro approach for preclinical safety and efficacy evaluation of ImmTAC molecules. This comprehensive testing package incorporates a series of cellular and molecular assays designed using human tissues and cultured cells. This strategy is meant to closely predict clinical responses and ensure safe first-in-human trials, sidestepping limitations of traditional animal models which often fail to recapitulate the human immune responses.
