SOUTH SAN FRANCISCO, Calif.--(BUSINESS WIRE)--Cortexyme, Inc. (Nasdaq: CRTX), a company advancing a pivotal trial in Alzheimer’s disease with top-line data expected by mid-November 2021 and a growing pipeline of therapeutics for degenerative diseases, announced the presentation of new data demonstrating evidence of P. gingivalis infection of the central nervous system in Alzheimer’s disease at the Annual Biomarkers for Alzheimer’s Disease Summit taking place virtually on Wednesday, August 25, 2021, at 2:10 p.m. ET followed by a live Q&A at 3:40 p.m. ET.
In a featured speaker presentation titled “Use of Novel Biomarkers of P. Gingivalis Infection & Neuroinflammation in the GAIN Trial: An Ongoing Phase 2/3 Clinical Trial Assessing the Activity of Atuzaginstat in Patients with Mild to Moderate Alzheimer’s Disease,” Cortexyme’s Executive Vice President of Research and Development Leslie Holsinger, Ph.D., will present an analysis of anti-P. gingivalis antibodies in cerebrospinal fluid (CSF) with results demonstrating that:
- All patients analyzed at baseline in the GAIN Trial (472 out of 472 baseline CSF samples available) were positive for anti-P. gingivalis antibodies (IgG) in their cerebrospinal fluid;
- Less than 2% of patients analyzed had a leaky blood brain barrier, as defined by an albumin index greater than 9; and
- Anti-P. gingivalis IgG in the CSF was only very weakly correlated to the albumin index (r=0.22), indicating production in the central nervous system in addition to that shown previously in serum.
These data add to the growing body of evidence indicating the presence of a P. gingivalis infection within the central nervous system in patients with Alzheimer’s disease. Cortexyme will also present other novel biomarkers developed to track markers of P. gingivalis and Alzheimer’s disease, in addition to highlighting the upstream role that P. gingivalis plays in key pathologies of Alzheimer’s disease progression. The complete presentation will be available here.
About The GAIN Trial
Cortexyme is pioneering an innovative, upstream, and disease-modifying therapeutic approach to Alzheimer's disease. The Phase 2/3 GAIN Trial is a pivotal study in 643 patients with mild to moderate Alzheimer’s Disease. Cortexyme’s seminal discovery, along with confirmatory clinical and preclinical studies, demonstrate that the intracellular pathogen, P. gingivalis, is found in the brain of more than 90% of Alzheimer’s patients and that an oral infection with P. gingivalis in animals results in brain infiltration and downstream hallmark Alzheimer’s pathologies, including Aβ42 production, tau hyperphosphorylation, microglial activation, and neurodegeneration. The company’s lead drug candidate, atuzaginstat (COR388), is a first-in-class, orally administered, brain penetrant small molecule targeting P. gingivalis, which is upstream of neuronal death and Alzheimer’s disease pathology. Atuzaginstat blocks gingipains, protease virulence factors secreted by P. gingivalis, which are required for its survival and responsible for its toxicity. The GAIN Trial also includes a REPAIR sub-study of 233 patients targeting P. gingivalis – a keystone bacterium associated with periodontal disease – and measuring the efficacy of atuzaginstat on clinical endpoints of periodontal disease. Cortexyme’s innovative therapeutic approach continues to be supported by research from laboratories around the world published in peer-reviewed scientific journals.
Cortexyme, Inc. (Nasdaq: CRTX) is a clinical stage biopharmaceutical company pioneering upstream therapeutic approaches designed to improve the lives of patients diagnosed with Alzheimer’s and other degenerative diseases. The company is advancing its disease-modifying pivotal GAIN Trial in mild to moderate Alzheimer's disease with top-line data expected by mid-November 2021, in addition to growing a proprietary pipeline of first-in-class small molecule therapeutics for Parkinson’s disease, periodontitis, and other diseases with high unmet clinical need. Cortexyme’s lead program targets a specific, infectious pathogen called P. gingivalis found in the brain and other organs and tied to degeneration and inflammation in humans and animal models. The company’s causation evidence for Alzheimer’s disease and the mechanism of its novel therapeutic has been independently replicated and confirmed by multiple laboratories around the world, as well as published in peer-reviewed scientific journals.
