COR388 is an irreversible active‐site inhibitor developed to target lysine‐gingipain (Kgp) in the brain of Alzheimer's disease (AD) patients. 1 Kgp is a cysteine protease virulence factor secreted by Porphyromonas gingivalis, a keystone bacterium in the development of periodontal disease. 2 The secretion of gingipain proteases is part of the asaccharolytic metabolism of P The third Cortexyme presentation, titled "COR388 (atuzaginstat), a novel gingipain inhibitor, decreases ApoE fragmentation in the CNS of Alzheimer’s disease patients" (Abstract 40578P3 The Phase I clinical trial designed to examine safety and tolerance of CO4388 was completed in October of 2018. The Phase 1 study enrolled 33 subjects into 4 different cohorts.

44 Views. 0 Downloads. 0 Gingipain inhibition reduced the bacterial load of an established P. gingivalis brain infection, blocked A 1–42 pro-duction, reduced neuroinflammation, and rescued neurons in the hippocampus. These data suggest that gin-gipain inhibitors could be valuable for treating P. gingivalis brain colonization and neurodegeneration in Alzheimer’s disease. However, periodontal disease is a major co-morbidity in Alzheimer’s disease and gingipain inhibitors acting to reduce microglial activation and the expression of pro-inflammatory mediators may well have a significant impact on disease progression. This paper makes a compelling argument to find out. The present invention relates generally to therapeutics targeting the bacterium Porphyromonas gingivalis , including its protease Lysine gingipain (Kgp), and their use for the treatment of disorders associated with P. gingivalis infection, including brain disorders such as Alzheimers disease.

In this study, a novel, potent, dual inhibitor of Rgp and Kgp was developed through structure‐based drug design, and its biological potency was evaluated in vitro and in vivo. At the minimal concentration of 17.826 μM, inhibition up to 98.7% and 89.4% was noted for gingipain R and K respectively.
