What the trial is, and whether it could suit you
CORT-X will examine if mitigation of stress-mediated pathogenesis of Alzheimer's disease (AD) is a feasible target for intervention in individuals at risk for this disease. This single-site (Baltimore, Maryland) phase II clinical trial is a 2-week, randomized, placebo-controlled crossover study of the effects of the selective glucocorticoid receptor antagonist, CORT108297, on cognitive test performance in 26 individuals with mild cognitive impairment (MCI) due to AD and in 26 cognitively normal individuals with an increased risk for AD due to family history, genetics, and/or subjective memory complaints. All subjects will participate in a brief stressor (public speaking and mental arithmetic) and provide saliva samples so investigators can measure stress hormone response. Then, following 2 weeks of treatment with placebo or CORT108297, in counterbalanced order, participants will complete
