Elezanumab Chemical Properties,Usage,Production
Uses
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].
in vivo
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].
| Animal Model: | Female Lewis rat optic neuritis models[1] |
| Dosage: | 1, 3, or 10 mg/kg |
| Administration: | IV; once a week for 5 doses |
| Result: | Protected against the optic nerve inflammationinduced RNFL degeneration. Showed significant protection of the RNFL, as demonstrated by decreased reduction in RNFL thickness measured by optical coherence tomography (OCT) with 10 mg/kg |
