Compare Subjective Drug Liking & Pharmacokinetics of Vyvanse™ and ADDERALL XR® When Administered as an Oral Solution

Study Overview
=================
Brief Summary
-----------------
The purpose of this study is to compare subjective drug liking using the Drug Rating Questionnaire, subject version (DRQ-S), question 2 and pharmacokinetics of Vyvanse™ and ADDERALL XR® when administered as an oral solution. Hypothesis: DRQ-S, question 2 will show no difference between the two drugs

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: Vyvanse™<br>50mg capsule that has been emptied and made into solution | Drug: Lisdexamfetamine Dimesylate<br>* Study is a two-period cross-over design where subjects will have 2 Screening visits, a Baseline visit, and then be enrolled into the study for 2 Periods. Each Period has 2-3 visits and lasts from 2-6 weeks. At each Period visit subjects will be given one of the two treatment arm drugs that have been solubilized and then have blood drawn for pharmacokinetic analysis and the Drug Rating Questionnaire administered. At the end of Period 1 subjects will be crossed-over to the alternative treatment drug for the Period 2. The Vyvanse™ capsule contents will emptied into water to make a solution and given to subjects to drink at the beginning of each Period visit.<br>|
| Experimental: ADDERALL XR®<br>20mg capsule that has been emptied, crushed, and made into solution | Drug: Racemic mixture of dextroamphetamine and lisdexamfetamine<br>* Same visits as described for Vyvanse™. The ADDERALL XR® capsule contents will be crushed, solubilized with water, and given to subjects to drink prior to pharmacokinetic blood draws and DRQ-S administration over the course of two periods.<br>|

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Drug Rating Questionnaire-Subject (DRQ-S), Question 2 | Question 2: How much do you like the effects you are feeling now? Questions are rated on a 29-point scale from 1 (not at all) to 29 (an awful lot). The higher the score the stronger the subjective experience. This is a subjective measure of a drug's effect that has been used to assess the abuse potential of drugs. | Pre-dose and 0.5, 1, 1.5, 2, 2.5, 3, 3.5, 4, 5, 6, 7, 8, 12 and 24 hours post-dose | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| DRQ-S, Question 1 | Question 1: How much do you feel the drug now? Questions are rated on a 29-point scale from 1 (not at all) to 29 (an awful lot). The higher the score the stronger the subjective experience. This is a subjective measure of a drug's effect that has been used to assess the abuse potential of drugs. | Pre-dose and 0.5, 1, 1.5, 2, 2.5, 3, 3.5, 4, 5, 6, 7, 8, 12 and 24 hours post-dose | 
| DRQ-S, Question 3 | Question 3: Do you dislike the drug effect you are feeling now? Questions are rated on a 29-point scale from 1 (not at all) to 29 (an awful lot). The higher the score the stronger the subjective experience. This is a subjective measure of a drug's effect that has been used to assess the abuse potential of drugs. | Pre-dose and 0.5, 1, 1.5, 2, 2.5, 3, 3.5, 4, 5, 6, 7, 8, 12 and 24 hours post-dose |
