Trial of CORT108297 to Attenuate the Effects of Acute Stress in the Allocortex (CORT-X)
This Phase 2 trial tests whether a drug called CORT108297 — which blocks a stress hormone receptor — can protect memory and thinking skills when the brain is under acute stress. Researchers are comparing two weeks of the drug against placebo in people with early memory problems or those at elevated risk for Alzheimer's. Phase 2 means they are gathering early evidence on whether it works and checking for side effects, not yet proven or approved.
