Elezanumab (ABT-555; AE12-1Y-QL) is a human monoclonal antibody that selectively targets repulsive guidance molecule A (RGMa). Elezanumab potently inhibited RGMa mediated BMP signalling via the SMAD1/5/8 pathway, with an IC50 around 97 pM. Elezanumab promotes neuroregeneration and neuroprotection in neuronal injury and demyelination models binds N-terminal RGMa, blocks BMP signaling and lacks RGMc cross-reactivity. elezanumab has neuroregenerative and neuroprotective activities without impact on iron metabolism[1][2].
Elezanumab (ABT-555; AE12-1Y-QL; 1-10 mg/kg; IV; once a week for 5 doses) promotes axonal regeneration and prevents retinal nerve fiber layer degeneration in the optic nerve crush and optic neuritis models (female Lewis rats)[1].
Elezanumab (0.01, 0.1, 1, 10 mg/kg; IV; once a week for 3 doses ) promotes axonal regeneration and remyelination, decreases inflammatory lesion area and improves functional recovery in the spinal targeted experimental autoimmune encephalomyelitis (EAE) model (female Lewis rats)[1].
