GPRC5D x CD3 bispecifics for targeting multiple myeloma
The Target: GPRC5D
GPRC5D is a receptor protein expressed at high levels in multiple myeloma, a bone marrow cancer. With the exception of hair follicles, where it is expressed at a lower level, it is absent from most healthy tissue.
Its restricted expression profile makes GPRC5D an optimal target for potent therapeutic modalities, including bispecifics.
GPRC5D is a complex membrane protein expressed in multiple myeloma cells.
Therapeutic Potential: Optimized format for targeting multiple myeloma
Using our proprietary MPS Antibody Discovery platform, we generated and selected highly specific, humanized GPRC5D MAbs. We combined these with a selection of formats and CD3-binding partner arms to build a diverse panel of GPRC5D x CD3 bispecific molecules.
We screened the panel for target binding, T cell-directed cytotoxicity, and cytokine release and selected candidate molecules with the best properties for targeting multiple myeloma. Lead candidates show picomolar potency and low cytokine release.
To ensure specificity, we screened the lead candidates using our Membrane Proteome Array™. They are highly specific to the intended target, with no off-target binding, minimizing the risk of off-tissue toxicity.
The Opportunity: Highly specific humanized GPRC5D x CD3 bispecifics
We have a lead molecule and back-ups ready for preclinical development. These are potent, highly specific molecules optimized for killing multiple myeloma cells.
