1. Solanezumab biosimilar is a humanized IgG1κ antibody against human amyloid-β protein precursor(APP).
2. APP is cleaved into Aβ42 and Aβ40,and Aβ42 drives the formation of neurofibrillary tangles, i.e.,intraneuronal protein clusters, and extracellular Aβ aggregates (senile plaques) causing Alzheimers.
3. Solanezumab binds preferentially with soluble monomers rather than fibrillar beta-amyloid or abeta (i.e., it does not bind Aβ’s aggregated
forms).
4. Solanezumab is shown to promote Aβ clearance from the brain in mouse models.
