Cortexyme Announces Gain Trial in Alzheimer’s Disease Has Reached Enrollment Milestone of 300 Patients
- Sub-study shows greater than 90% of enrolled patients have moderate to severe periodontal disease, indicating relevance to mechanism of action against P. gingivalis
- Interim analysis of the Phase 2/3 GAIN Trial expected to occur before year-end 2020
SOUTH SAN FRANCISCO, Calif.--(BUSINESS WIRE)-- Cortexyme, Inc. (Nasdaq: CRTX) today announced that enrollment in its GAIN Trial for Alzheimer’s disease has reached 300 patients toward the study’s previously announced enrollment target of 570 subjects. GAIN is a randomized, double-blind, placebo-controlled Phase 2/3 trial of COR388, Cortexyme’s lead investigational medicine, in patients with mild to moderate Alzheimer’s disease. GAIN’s protocol includes an interim analysis for overwhelming efficacy on its co-primary cognitive and functional endpoints after 300 patients reach six months of treatment; this interim analysis is expected to occur before year-end 2020. Top-line results from the GAIN Trial’s final analysis, to be performed once all study subjects complete one year of treatment, are expected in Q4 2021.
The target of COR388, gingipains produced by P. gingivalis, have been discovered in the brain of Alzheimer’s patients and shown to produce Alzheimer’s pathology in infected animals. P. gingivalis is best known as a keystone bacterium in the development of periodontal disease. The GAIN Trial includes a periodontal sub-study, in which approximately 40% of GAIN Trial participants are also assessed for endpoints of efficacy in periodontal disease. The GAIN Trial and the sub-study did not specify inclusion criteria related to periodontal status, and yet greater than 90% of patients enrolled had moderate to severe periodontal disease at baseline.
“We are pleased with the high level of engagement of our clinical sites and study participants, as well as with the operational execution of our team,” said Michael Detke, M.D., Ph.D., Cortexyme’s chief medical officer. “The pace of enrollment in the GAIN Trial reflects the need for new therapeutic options for patients with Alzheimer’s disease and the interest in our upstream mechanism of action. We believe we are enrolling the right patients at the right time and we look forward to presenting study results when available.”
