A D1 Agonist For Working Memory
United States120 participantsStarted 2013-04
Plain-language summary
The purpose of the study is to examine the effects of the administration of a drug called DAR-0100A on attention and memory in persons with schizotypal personality disorder (SPD). DAR-0100A has not been FDA approved, however in recent studies has been used to treat cognitive deficits, meaning problems in the way you organize your thinking, in people diagnosed with schizophrenia.
Many people who carry a diagnosis of schizotypal personality disorder have trouble with attention and memory. Increasing the presence of a brain chemical called dopamine has been found to help people with schizophrenia with their attention and memory problems. This study will investigate whether the same is true for people with schizotypal personality disorder by using DAR-0100A, a drug that has been shown to help with the cognitive deficits of people with Parkinson's disease by increasing dopamine effects. Information collected in this experiment may lead to a better understanding of the brain mechanisms involved in schizotypal personality disorder and improve treatments for the psychological problems associated with this condition.

Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
