ITEM 8.01

Other Events.

On October 26, 2021, Cortexyme, Inc. (the “Company”) reported top-line results from its Phase 2/3 GAIN Trial, a double-blind, placebo-controlled study evaluating the efficacy of atuzaginstat (COR388), an investigational orally administered small-molecule that targets gingipain proteases from the bacterium Porphyromonas gingivalis (P. gingivalis). The 643-participant study in mild to moderate patients with Alzheimer’s disease did not meet statistical significance in its co-primary cognitive and functional endpoints as measured by ADAS-Cog11 and ADCS-ADL at end of the treatment period in the overall cohort.

The pre-specified subgroup of participants with P. gingivalis DNA detectable in saliva at baseline (PG-DS; n=242) showed a dose response, with a 57% slowing of cognitive decline as measured by ADAS-Cog11 in the 80 mg BID arm (p=0.02) and a 42% slowing in the 40 mg BID arm (p=0.07) vs. placebo. Significant benefits in this subgroup were not seen on the other co-primary, ADCS-ADL. The cognitive benefit of atuzaginstat in patients with high P. gingivalis infection was reinforced by similar results in multiple pre-specified infection related subgroups and with multiple methods of analysis. Additionally, reductions in P. gingivalis in saliva at week 24 were significantly correlated with improved outcomes at the end of the treatment period as measured by ADAS-Cog11 (p=0.0007), Clinical Dementia Rating–Sum of Boxes (CDR) (p=0.004), Mini-Mental State Exam (MMSE) (p=0.007), and a beneficial trend on ADCS-ADL (p=0.08).

The sub-study in periodontal disease demonstrated a trend to benefit on the primary clinical endpoint of pocket depth in the same pre-specified sub-group with P. gingivalis DNA detectable in saliva. Further results will inform the next stage of development in periodontitis and will be presented at a future scientific conference.

Most adverse events were mild to moderate in severity. The most common were gastrointestinal, such as diarrhea in up to 16% and nausea in 6% of participants treated with atuzaginstat vs. 3% and 2% of placebo participants, respectively. Atuzaginstat was associated with dose-related liver enzyme elevations >3X the upper limit of normal: 2% on placebo, 7% on 40 mg BID, and 15% on 80 mg BID. These elevations alone were not clinically significant, and virtually all participants were asymptomatic. Two participants in the 80 mg BID arm had concomitant bilirubin elevations without alternative explanation. Lab changes resolved while participants remained on drug or after withdrawal without any known long-term adverse effects. Atuzaginstat treated groups showed no increase in ARIA (amyloid-related imaging abnormalities), including microhemorrhage and edema, or superficial siderosis.

In light of the GAIN Trial results and the significant unmet medical need in Alzheimer’s, the Company is actively engaging with regulators, the medical community, patient advocacy groups, and other key stakeholders to advance development of atuzaginstat and the second-generation lysine-gingipain inhibitor COR588, which is differentiated by novel compound properties and once daily administration.
