TCR-like binders
ECLIPSE has created a comprehensive sample library, enabling research to reveal novel binders that may allow targeting blood cancer cells in a way that is distinct to CAR-T therapies. These binders are T cell receptor (TCR)-like antibodies that find cancer cells in a similar immune matching mechanism as during organ donor matching for transplantation.
The important benefits of TCR-like binders are:
Resultantly, incorporating TCR binders into the OmniCAR armoury helps consolidate OmniCAR at the forefront of cellular immunotherapy innovation.
Initially, the collaboration will concentrate on a binder to an undisclosed target present in leukemic blasts and leukaemic stem cells, whose expression co-relates deeply with poor outcomes. Interestingly, this binder does not identify healthy bone marrow, thus possibly providing a distinctive combination of efficiency and safety.
Prescient and MD Anderson will equally bear the cost of the research, and both parties will have commensurate ownership of the resultant therapeutic product.
According to Dr Rebecca Lim, Prescient's Senior Vice President of Scientific Affairs, identifying and binding targets on the surface of tumour cells are major challenges in developing effective cancer therapies. In this regard, the ECLIPSE platform has provided important innovations in identifying and creating unique binders for these novel targets. It also overcomes the heterogeneity of antigen expression, enabling multiple targets to be addressed over time if the patient relapses.
