Insight Clinical Trials is Now Recruiting Patients for Clinical Trial Based on Transformational Understanding of Alzheimer’s Disease
The GAIN Trial will assess whether targeting bacteria associated with periodontal disease can slow or halt progression of Alzheimer’s disease
Insight Clinical Trials, located in Beachwood, OH, is now recruiting patients aged 55-80 years old with mild to moderate Alzheimer’s disease to participate in a clinical trial assessing a new investigational medicine that could slow the progression of Alzheimer's disease.
The GAIN (GingipAIN Inhibitor for Treatment of Alzheimer’s Disease) Trial is based on a growing body of scientific evidence that the P. gingivalis bacteria, most commonly associated with gum disease, or chronic periodontal disease, can infect the brain and cause Alzheimer’s. The study is evaluating whether COR388, an oral investigational medicine, can slow or halt the progression of Alzheimer’s by inactivating the toxic proteins, or gingipains, released by P. gingivalis that have been shown in animal studies to damage and destroy brain cells.
“We are proud to have been selected as a research site participating in this large international clinical trial to test a dramatically new way of understanding and treating Alzheimer’s disease,” said Mark Stillman M.D., Principal Investigator at Insight Clinical Trials. “For decades, much of the Alzheimer’s clinical research has focused on other approaches with little success. In the GAIN Trial, we are evaluating a completely different mechanism of Alzheimer’s. We are testing the hypothesis that bacteria can cause Alzheimer’s, and that inactivating the toxic proteins released by the bacteria can have a positive impact on stopping or slowing the progression of this devastating disease.”
The study drug, COR388, was designed by pharmaceutical company Cortexyme to inactivate the toxic gingipains created by the P. gingivalis bacteria, reduce inflammation, reduce the bacterial infection and slow or halt progression of Alzheimer’s disease. An earlier small clinical study showed COR388 was well-tolerated, with a promising trend of average improvement in the memory test performance for the Alzheimer’s patients in the study who took the drug compared to placebo.
Insight Clinical Trials is recruiting subjects who are 55 to 80 years old with a documented diagnosis of mild to moderate Alzheimer’s, among other criteria. To learn more, contact Brittney, at 216-526-1843, or email at info@insightclinicaltrials.com.
Scientists involved in the study recently released new findings
Researchers from study presented pre-clinical data at the Alzheimer's Association International Conference® 2020. See release:
Cortexyme Presents Data Linking P. gingivalis Infection to Cardiovascular Disease Severity and Alzheimer's Disease, Along With Evidence That Treatment With Atuzaginstat (COR388) Improves Biomarkers Associated With Both Diseases
-- Researchers presented new preclinical data on atuzaginstat and the potential impact on cardiovascular disease and AD-associated neurodegeneration in two poster presentations at AAIC 2020 -- Cortexyme also presented phase 1b clinical data demonstrating atuzaginstat‘s therapeutic potential in blocking AD-associated ApoE fragmentation
SOUTH SAN FRANCISCO, Calif.-- Cortexyme, a clinical stage biopharmaceutical company pioneering upstream therapeutic approaches to improve the lives of patients diagnosed with Alzheimer’s and other degenerative diseases, today announced new preclinical data demonstrating the role of the bacterium P. gingivalis in Alzheimer’s disease (AD) and cardiovascular disease, providing a potential explanation for why the two diseases often occur together. Cortexyme also provided data demonstrating the therapeutic potential of its lead compound, atuzaginstat (COR388), in treating both diseases. This data, along with two other poster presentations on atuzaginstat, are being presented by Cortexyme at the Alzheimer's Association International Conference® 2020 (AAIC®), which is taking place virtually from July 27-31.
“Atuzaginstat is the subject of the GAIN Trial, a Phase 2/3 clinical trial evaluating its potential to slow or halt Alzheimer’s disease progression by blocking the toxic proteases, or gingipains, released by P. gingivalis as it invades the brain,” said Casey Lynch, Cortexyme’s chief executive officer and co-founder, and a co-author of all three presentations. “As evidence mounts regarding P. gingivalis’ role in a variety of serious health conditions, including cardiovascular disease, we are pleased to play a leading role in the research and development of gingipain inhibitors, and believe that this novel class of compounds may have significant therapeutic breadth and applicability.”
The Role of P. gingivalis and Potential for Atuzaginstat in Cardiovascular Disease Previous research led by Cortexyme has demonstrated a causative association between the bacterial pathogen P. gingivalis and AD. Cortexyme’s lead gingipain inhibitor atuzaginstat has been shown to block the neuropathology triggered by P. gingivalis in animal models. Researchers have also found an association between P. gingivalis and the atherosclerotic plaques associated with cardiovascular disease, with a 2017 study by Mougeot et al. demonstrating P. gingivalis as the pathogen found most abundantly in coronary and femoral artery tissues in atherosclerosis and linked to the development of this disease pathology. In a poster presented at AAIC today, "Targeting Porphyromonas gingivalis to treat Alzheimer’s disease and comorbid cardiovascular disease" (Abstract 47058P3), researchers demonstrated that oral infection with P. gingivalis accelerated atherosclerosis in a rabbit model of disease and showed that atuzaginstat reduced inflammation and the formation of unstable atherosclerotic plaques. Specifically, the gingipain inhibitor reduced deposits of lipids in the aortas of infected animals and prevented the progression of atherosclerosis linked to P. gingivalis infection.
“Building on strong prior research linking P. gingivalis to cardiovascular disease, our research shows improvements in lipid deposition, progression of atherosclerosis and levels of systemic inflammation in the P. gingivalis-infected groups treated with atuzaginstat,” said Hatice Hasturk, D.D.S., Ph.D., director of the Center for Clinical and Translational Research at the Forsyth Institute and a principal investigator of the research presented today. “These data are highly suggestive that atuzaginstat may have therapeutic potential in mitigating cardiovascular disease in people with P. gingivalis infection, a common oral infection thought to effect more than 50% of the adult population, which is capable of promoting systemic infection and inflammation.”
“We are proud to lead global research demonstrating the role of P. gingivalis in Alzheimer’s disease and, in turn, the therapeutic potential for the gingipain inhibitor atuzaginstat in treating and preventing Alzheimer’s pathology,” said Stephen Dominy, M.D., Cortexyme’s chief scientific officer and co-founder, and co-author on the presentation. “We are encouraged by this new data demonstrating the potential impact of atuzaginstat on cardiovascular disease, a condition where P. gingivalis has previously been implicated, and believe this therapeutic approach warrants further study.”
Cortexyme’s work was featured in two additional poster presentations at the virtual AAIC 2020 event: Atuzaginstat Protects Against AD-Associated Synaptic Loss In a poster titled “Comprehensive Alzheimer’s pathology is induced by Porphyromonas gingivalis infection: atuzaginstat (COR388) and other proprietary gingipain inhibitors protect against synaptic loss” (Abstract 44023P1), researchers showed additional evidence supporting COR388 as a potential AD therapy. This study, conducted in neuron cultures and neuron-astrocyte-microglia co-cultures, showed that atuzaginstat and proprietary gingipain inhibitors protected neurons infected with P. gingivalis from synapse loss. Additionally, atuzaginstat reduced the bacterial load in neurons, astrocytes and microglia infected with P. gingivalis and protected against deficits in other pathways impacted by the bacterium, including synaptic transmission.
Atuzaginstat Also Decreases ApoE Fragmentation 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. Data from Cortexyme’s Phase 1b trial of atuzaginstat show that gingipains preferentially fragment the ApoE4 protein variant, suggesting why the APOE4 gene variant may increase the risk of developing AD, i.e., the protein is more susceptible to gingipain cleavage and, in turn, AD-associated neurodegeneration.
