Drug intelligence / Profile preview
PeptiClere (also known as PTI-777) is a peptide-based therapeutic candidate developed by ProteoTech, Inc. for the treatment of Alzheimer's disease. Administered as a nasal spray, the drug is designed to target and inhibit the aggregation of amyloid-beta (Aβ) proteins into toxic fibrils and plaques, which are central to the pathogenesis of Alzheimer's. Additionally, PeptiClere is intended to promote the clearance of existing amyloid deposits in the brain. The intranasal delivery route is utilized to facilitate direct transport to the central nervous system, potentially improving efficacy and reducing systemic side effects. Development of the compound appears to have ceased following the inactivity of ProteoTech.
