Cortexyme Presents Data Supporting Role of P. Gingivalis in

COR388 is a small-molecule inhibitor of gingipains, which are proteins that are released by bacteria species (p.gingivalis) that commonly reside in the mouth. Previous studies have shown that people with bacterial gum disease have a higher risk of developing Alzheimer’s disease ( AD ), and that people with AD have elevated levels of gingipain in their brains, associated with infiltratingp Porphyromonas gingivalis and its proteolytic virulence factors lysine‐gingipain (Kgp) and arginine‐gingipain (Rgp) are emerging as major etiologic agents in the pathogenesis of Alzheimer’s disease (AD).

TWiM 195: Gingipain in the Alzheimer brain March 4, 2019 Michael and Vincent discuss the finding of immunity to Cas9 protein in humans, and a potential role for an oral bacterium in Alzheimer’s disease. The level of gingipain inhibition can range from about 5% to about 95%, or from about 10% to about 90%, or from about 20% to about 80%, or from about 30% to about 70%, or from about 40% to about 60%.

We A lysine gingipain inhibitor of the invention can be administered in the same composition as an additional therapeutically active agent. Alternatively, the additional therapeutically active agent can be administered separately before, concurrently with, or after administration of the lysine gingipain inhibitor. Pretreatment with gingipain inhibitors protected neuron cell degradation caused by administration of gingipains in murine model. [citation needed] Capsular polysaccharide (CPS) The encapsulated strain of P. gingivalis is much more virulent than the nonencapsulated strain in a mouse abscess model. inhibition of Rgp gingipain activity (Table 1).

Toxic proteases from the bacterium called gingipains were also Oral administration of gingipain inhibitors to mice with established brain infections decreases the abundance of P. gingivalis DNA in brain and mitigates the neurotoxic effects of P. gingivalis infection. Thus, gingipain inhibition could provide a potential approach to the treatment of both periodontitis and AD. The third Cortexyme presentation, titled “COR388 (atuzaginstat), a novel gingipain inhibitor, decreases ApoE fragmentation in the CNS of Alzheimer’s disease patients” (Abstract 40578P3), presents Oral administration of gingipain inhibitors to mice with established brain infections decreases the abundance of P. gingivalis DNA in brain and mitigates the neurotoxic effects of P. gingivalis infection. Thus, gingipain inhibition could provide a potential approach to the treatment of both periodontitis and AD. 1 INTRODUCTION This small molecule gingipain inhibitor is atuzaginstat, and it's being studied by CRTX in late stage studies in periodontitis and Alzheimer’s, the latter is, of course, the value driver. Pipeline The third Cortexyme presentation, titled “COR388 (atuzaginstat), a novel gingipain inhibitor, decreases ApoE fragmentation in the CNS of Alzheimer’s disease patients” (Abstract 40578P3), presents data indicating P. gingivalis gingipains target and cleave ApoE proteins in the nervous system of AD patients.

Holsinger1, Casey Lynch1, Stephen Dominy1 BACKGROUND Background Pretreatment of mice with gingipain inhibitors protected their hippocampal neurons from the neurotoxic effects of injecting gingipain directly into the hippocampus. Furthermore, gingipain inhibitors protected the cultured cells from the toxic effects of P. gingivalis , whereas antibiotics, such as moxifloxacin and doxycycline, or semagacestat The GAIN (GingipAIN Inhibitor for Treatment of Alzheimer’s Disease) Trial is a randomized, double-blind, placebo-controlled Phase 2/3 trial evaluating the efficacy, safety, and tolerability of The third Cortexyme presentation, titled “COR388 (atuzaginstat), a novel gingipain inhibitor, decreases ApoE fragmentation in the CNS of Alzheimer’s disease patients” (Abstract 40578P3), presents data indicating P. gingivalis gingipains target and cleave ApoE proteins in the nervous system of AD patients.
