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
