After your baseline testing, you will be given your first dose of atiprimod. During the first 8 hours after your first dose of atiprimod, you will be watched for any side effects that might occur. You will have several blood samples taken during this period for PK testing. About a quarter of a teaspoon of blood will be drawn 30 minutes after your first dose, then again at 60 minutes, 90 minutes, 2 hours, 3 hours, 4 hours, 6 hours, and 8 hours after your first dose, for a total of 2 teaspoons of blood drawn. After these blood collections, you will go home. You will be given a study diary for recording any other medications you take and how much you take, as well as any side effects that you experience. You will also be asked to record the type and amount of beverage consumed during the 2-hour period before taking atiprimod and the 2-hour period after taking atiprimod. You will be required to keep this diary up to date during your entire participation on study, and you must bring it to every study visit.
