Enhanced Discriminatory Receptors (EDR) – enhancing discriminatory power of T cells
Applications: CAR-T cell therapy
A platform technology that uses the T cell receptor alpha and beta chains to produce a CD3-independent enhanced discriminatory receptor exhibiting high on-target potency with dramatically reduced off-target cross-reactivity.
Features
Benefits
Uses existing candidate TCRs
Improves efficacy and reduces cross-reactivity (without modifying the TCR variable domains, i.e. no CDR changes required)
Modified signalling enables selective responses to high affinity on-target antigens
Reduced or abolished responses to lower-affinity off-target antigens (i.e. reduced cross-reactivity)
Surface expression is CD3-independent
No mispairing with endogenous TCRs
High surface expression
Can be expressed in any cell (T cells, NK cells, macrophages, etc)
