Study summary

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 cognitive tests assessing memory and executive function. All study participants will receive CORT108297 and placebo over the course of this 10-week trial that requires 6 in-person study visits. The primary aims will compare the effects of CORT108297 to placebo on cognitive test performance in individuals with MCI due to AD and in individuals at risk for AD, and describe the side effects of CORT108297 in study participants. Secondary aims will identify subject characteristics that predict positive response to study drug.

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Individuals must meet criteria for mild cognitive impairment due to Alzheimer's disease according to National Institute on Aging (NIA)/Alzheimer's Association recommendations OR be cognitively normal based on clinical and cognitive assessment in the Enrollment Visit and have at least one of the following risk factors for AD:

  • Known to have at least 1 apolipoprotein E (APOE) ε4 allele;

  • A first-degree relative with dementia.

Inclusion criteria

Inclusion Criteria for all subjects:

  • Willing and able to participate for the duration of the study.

Exclusion criteria

Exclusion Criteria for all subjects:

  • Participation in a therapeutic clinical trial at any time during the study;
  • Abnormal interval using Bazett's formula (QTcB; defined as > 450 ms for men and > 470 ms for women) as determined on ;
  • Any significant neurologic disease other than suspected incipient Alzheimer's disease, such as Parkinson's disease, multi-infarct dementia, Huntington's disease, normal pressure hydrocephalus, brain tumor, progressive supranuclear palsy, seizure disorder, subdural hematoma, multiple sclerosis, or history of significant head trauma followed by persistent neurologic deficits or known structural brain abnormalities, including lacunes in critical memory structures including the hippocampus and parahippocampal cortex;
  • Bipolar disorder within the past 1 year;
  • History of alcohol or drug dependence;
  • Any significant systemic illness or unstable medical condition, which could lead to difficulty complying with the protocol;
  • General surgery within the last 3 months;
  • Sensory impairment (poor vision or hearing) significant enough to interfere with ability to provide valid cognitive test data;
  • Treatment within the last six months with neuroleptics, sedative hypnotics, or ;
  • Treatment within the last six months with medications metabolized by the CYP2C9 or CYP2C19 enzymes, most notably clopidogrel and proton pump inhibitors;
  • Concurrent use of a inhibitor, including grapefruit juice, and St. John's Wort;
  • Exceptions to these guidelines may be considered on a case-by-case basis at the discretion of the PI.
Terms in these criteria, in plain language(6)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

BMI (body mass index)

Weight in kilograms divided by height in metres squared. Example: 70 kg and 1.75 m gives 70 ÷ (1.75 × 1.75) ≈ 22.9.

What counts as overweight or obesity differs between countries (some use lower cut-offs), so go by the range the study states.

Postmenopausal

Periods have stopped for good: usually no period for 12 months in a row without another medical reason, sometimes confirmed by a blood test (FSH).

QT and QTc

On an ECG, the QT interval is the time the heart’s lower chambers take to activate electrically and recover in each beat. QTc is that time adjusted for heart rate (QTcF by Fridericia’s formula, QTcB by Bazett’s). Some medicines lengthen it, and a long QTc can raise the risk of a dangerous heart rhythm.

The study may name a correction formula and a limit in milliseconds, often around 450–480.

ECG (electrocardiogram)

A recording of the heart’s electrical activity, taken with stickers on the chest, arms and legs. It takes a few minutes and does not hurt.

Corticosteroids (steroids)

Anti-inflammatory medicines such as prednisone, prednisolone and dexamethasone — not the anabolic steroids used for muscle.

Studies differ in what they allow: check which steroid medicines, routes (tablets, injections, creams, inhalers, eye drops) and doses this study accepts.

CYP3A (CYP3A4) inhibitors and inducers

CYP3A is a group of enzymes, mainly CYP3A4, in the liver and gut that break down many medicines. Some medicines, supplements and foods (grapefruit, St John’s wort) slow them down or speed them up, which changes how much of a study drug stays in the body.

Studies list them so they can be avoided or switched; bring a list of everything you take, including supplements.

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Started Jun 2021 (actual). Primary completion is estimated for Nov 2027, 77 months after the start.

Of 145 non-industry phase 2 interventional studies under Cognitive Dysfunction, half reached primary completion within 53 months of starting (the median), counting those still running; a quarter within 29 and three quarters within 64. This study's planned 77 months is above that.

Counting every sponsor, half of 186 studies reached it within 44 months; a quarter within 22 and three quarters within 62.

How these figures are worked out, and which studies are left out of them.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Jul 13, 2026, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
