Driving Immune-Control of Solid Tumors

Revitope is developing a novel class of T cell engaging antibody circuits that redirect T cells to tumors with broad therapeutic applications in immuno-oncology.

Immune-based therapies are redefining how cancer is treated, as clinical studies demonstrate unprecedented deep and durable responses in multiple cancer types. In particular, redirecting T cells to tumors is a successful strategy for immunotherapy, but to date is limited by off-target toxicities and imperfect targets for solid tumors.

Revitope's engineered programmable antibody circuits are focusing immune activation to the cancer cell surface while expanding the antigenic targeting space on solid tumors to widen the therapeutic index in immuno-oncology.

    About Revitope's T-Cell Engaging Antibody Circuit Technology (TEAC): Tumor-specific Immunotherapies

    Because tumors typically do not express cell surface proteins unique to the tumor, conventional bispecific antibody therapeutics can generate unwanted and substantial "on-target, off-tumor" toxicity. Revitope's two-component T-cell engaging antibody circuits (TEACs) are designed to permit specific recruitment and activation of T-cells exclusively by tumor cells. Though developed with traditional tumor targeting domains, TEAC therapies split the CD3 paratope (the T-cell recognition domain) into two halves, with one half on one molecule and the other half on the other molecule. This allows for true dual-antigen targeting to a unique tumor-specific address – two inputs coming together to enable one precision targeted output i.e. a true "and" gate safety feature. Only when the two molecules come together through binding to their different tumor targets on the same tumor cell can the two halves of the CD3 binding domain recombine and create a fully functional anti-CD3 domain (a TEAC). Normal cells expressing only one or neither of the targeted antigens will not elicit activation of a TEAC pair thereby avoiding unwanted toxicity in healthy tissues.
