Brief summary

Emestedastat was created to decrease the production of cortisol by the brain. This drug has been previously tested in nearly 400 people, including healthy adults and people with Alzheimer’s Disease and depression. The research project will test what the body does to emestedastat, such as how quickly it enters, moves through, and leaves the body. In particular, the research project will test if eating food has any effect on what happens to emestedastat in the body. If this and other clinical research projects are successful, the treatment being studied may be approved to treat people with Alzheimer’s Disease or depression in the future.

Interventions

emestedastat 10 mg oral tablet, 2 single doses, with a washout period of one week between treatments. Doses will be taken in either the fasted or fed state, both states are under assessment. Doses will be taken under supervision and will be checked by a second member of staff. A hand and mouth check will be conducted after each participant has been dosed. The fed state involves consumption of a high fat and high calorie meal during a 30-minute period that commences 45 minutes prior to dosing. It

The fed state involves consumption of a high fat and high calorie meal during a 30-minute period that commences 45 minutes prior to dosing. It should derive approximately 150, 250, and 500 to 600 calories from protein, carbohydrate, and fat, respectively, as defined in regulatory guidance.
