The GAIN (GingipAIN Inhibitor for Treatment of Alzheimer’s Disease) Trial is based on a growing body of scientific evidence that the bacteria P. gingivalis, most commonly associated with degenerative gum disease, can infect the brain and cause Alzheimer’s disease.

Gingipain inhibition reduced the bacterial load of an established P. gingivalis brain infection, blocked Aβ 1-42 production, reduced neuroinflammation, and rescued neurons in the hippocampus. These data suggest that gingipain inhibitors could be valuable for treating P. gingivalis brain colonization and neurodegeneration in Alzheimer's disease.

A bacteria that causes gum disease has been linked to Alzheimer's disease in a study scientists believe could pave the way for new treatments targeting the debilitating condition. Many companies have phase II clinical trials exploring the mABs targeting tau but there are drugs in development targeting tau that are not mABs. Non-amyloid methods also include the gingipain inhibitor (Corteyme -COR388). Gingipains are byproducts of oral bacteria p. gingivalis and have been shown to be neurotoxic.

Abstract: Many efforts have been made to develop therapeutic agents for Alzheimer’s Disease (AD) based on the amyloid cascade hypothesis, but there is no effective therapeutic agent at present. 2019-5-2 2021-2-9 2021-4-9 · The path to tackling Alzheimer's disease is littered with failures, but when a company generates even early hints of promise the rewards are high.

COR388 (atuzaginstat), a novel gingipain inhibitor, decreases ApoEfragmentation in the CNS of Alzheimer’s disease patients. Debasish Raha1, Sean Broce1,Ursula Haditsch1,Leo Rodriguez1, Florian Ermini1, Michael Detke1, Shirin Arastu-Kapur1, Dave Hennings1, Mai Nguyen1, Leslie J. Holsinger1, Casey Lynch1, Stephen Dominy1. BACKGROUND. No, we don’t know that gum disease causes Alzheimer’s A new study suggests a link between oral bacteria and Alzheimer’s, but it’s far from proven Evidence of P. gingivalis infiltration has been detected in autopsy specimens from the brains of people with AD and in cerebrospinal fluid of individuals diagnosed with AD. Gingipains, a class of P. gingivalis proteases, are found in association with neurons, tau tangles, and beta-amyloid in specimens from the brains of individuals with AD. 2021-02-16 · As a result of the partial clinical hold on atuzaginstat, Cortexyme will halt enrollment of any new participants in the open-label extension phase of the GAIN (GingipAIN Inhibitor for Treatment of Alzheimer’s Disease) trial. The double-blind, randomized, placebo-controlled trial has been fully enrolled at 643 participants with AD. The GAIN Clinical Trial The GAIN Trial (GingiPAIN inhibitor for treatment of Alzheimer’s disease) is a pivotal Phase 2/3 randomized, double-blind, placebo-controlled study that is assessing the efficacy, safety, and tolerability of two dose levels of COR388 oral capsules in subjects with mild to moderate Alzheimer’s disease.

The investigators, including Stephen Dominy, MD, the chief scientific officer of Cortexyme, which has developed a gingipain inhibitor, CORE-388, identified the pathogen in the brains of patients with Alzheimer disease, as well as the organism’s gingipains—lysine-gingipain (Kgp), arginine-gingipain A (RgpA), and arginine-gingipain B (RgpB)—in the neurons of these patients. Gingipain inhibition reduced the bacterial load of an established P. gingivalisbrain infection, blocked Aβ1-42production, reduced neuroinflammation, and rescued neurons in the hippocampus. These data suggest that gingipain inhibitors could be valuable for treating P. gingivalisbrain colonization and neurodegeneration in Alzheimer's disease. People with Alzheimer’s disease have elevated levels of the bacterial protease gingipain in their brain tissue, they find.

The team has identified three small molecule gingipain inhibitors. The first two, COR286 and COR271 are irreversible inhibitors and have IC 50 values less than 50 pM. And a third molecule COR119 is a reversible inhibitor with an IC 50 of 10 nM.

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.
