A Safety and Effectiveness Study of JNJ-31001074 in Adults With Attention-Deficit/Hyperactivity Disorder.

This study is being done to assess safety and tolerability and to explore the effectiveness of a new, experimental drug in the treatment of attention deficit hyperactivity disorder in adults. Approximately 144 adult patients with ADHD will be recruited for the study. Patients who meet study criteria will need to stop taking any ADHD medications they are currently using. They will be randomly assigned to one of 3 treatment arms; each patient has an equal chance of receiving 10 mg JNJ-31001017, 30 mg JNJ-31001074, or placebo. Placebo has no active drug. This is a blinded study, i.e. the patient, the study doctor and the study sponsor will not know what treatment the patient receives until all patients complete the study. Patients will be dispensed a bottle containing study drug for the upcoming week at 4 of the study visits. The study doctor and the sponsor will monitor the study for the occurrence of possible side effects. In addition to a screening visit, patients will return weekly for 6 additional study visits including an end of study visit and a follow-up visit. Patients will take study drug for a total of 4 weeks. After completing the study, patients may resume other ADHD medications. Medical and ADHD history, physical examination, blood pressure, heart rate, temperature, weight and ECGs will be checked periodically throughout the study. Blood samples will be taken for standard safety laboratory tests as well as for the measurement of the drug blood level. Questionnaires relating to ADHD and cognitive testing will be administered throughout the study. Each day for four weeks, patients will take orally, at least one hour before eating in the morning, 1 tablet containing either 10 mg JNJ-31001074, 30 mg JNJ-31001074 or placebo.
