Once daily dose of COR588 over 10-day period well-tolerated with no serious adverse events observed
SOUTH SAN FRANCISCO, Calif.--(BUSINESS WIRE)--Jul. 27, 2022--
Cortexyme, Inc. (Nasdaq: CRTX), a clinical-stage biopharmaceutical company focused on advancing therapeutics for rare and degenerative diseases, today reported the successful completion of its Phase 1 single ascending dose and multiple ascending dose (SAD/MAD) clinical trial of COR588, the company’s lysine gingipain inhibitor in development for the treatment of Alzheimer’s disease and indications with disease pathology associated with the keystone pathogen P. gingivalis. The study was a randomized, double-blind, placebo-controlled, first-in-human study to evaluate the safety, tolerability, and pharmacokinetics of COR588 in healthy adult participants.
Previously announced in March 2022, the SAD portion of the Phase 1 clinical trial demonstrated that COR588 was well-tolerated across all cohorts in the dose range from 25 mg to 200 mg with no serious adverse events. No clinically significant findings were observed on safety measures, including vital signs, laboratory findings, telemetry, or ECGs. No clinical chemistry or hematology safety concerns were observed at any dose. Additionally, COR588 exhibited an 11-to-12-hour half-life consistent with once daily dosing and a dose-proportional pharmacokinetic profile that importantly achieved the targeted exposure predicted for therapeutic efficacy.
The MAD portion of the Phase 1 clinical trial of COR588 demonstrated that once daily oral administration of COR588 over a 10-day period was well-tolerated across all cohorts in the dose range from 50 mg to 200 mg with no serious adverse events observed. High central nervous system penetration of COR588 was confirmed after 10 days of administration.
Cortexyme will provide an update on the development path forward for COR588 in conjunction with its planned corporate name change to Quince Therapeutics and detailed go-forward growth strategy that is expected to be announced on August 1, 2022.
