Details and patient eligibility

About

This study will examine SPD489 in subjects aged 18-65 with major depressive disorder (MDD) who are taking certain types of antidepressants but continue to have residual depression symptoms. Eligible patients will remain on their antidepressant but will be randomized to either receive supplemental SPD489 or placebo (i.e. sugar pill). The purpose of this study is to help answer the following questions:

How safe is SPD489 for the supplemental treatment of depression and what are the side effects that might be related to it?
Can supplemental SPD489 help patients who still have residual depression symptoms while taking an antidepressant?
How much SPD489 should be given to patients with depression who are also taking an antidepressant?
How does SPD489 compare to placebo in depressed patients who are also taking an antidepressant?
