Our Princeton, NJ site is currently enrolling subjects with ADHD into research studies. Our studies seek to determine the safety and efficacy of an investigatory drug for the treatment of those with the disease. All study related visits, laboratory work, medications, and procedures – including physical exams – are provided at no cost to those who qualify for the study. Qualified participants will receive compensation for time and travel. Other criteria for eligibility will be discussed with interested persons, without obligation.
