| E.2 Objective of the trial |
| E.2.1 | Main objective of the trial |
The primary objective is to evaluate the long-term safety and tolerability of SPD489 administered as a daily morning dose (20, 30, 50, and 70mg/day) as adjunctive therapy to an antidepressant for the treatment of major depressive disorder (MDD) in adults (18-65 years of age inclusive at the time of consent for the respective short-term antecedent SPD489 MDD study). Long-term safety will be described using:
• Occurrence of treatment-emergent adverse events (TEAEs),
• Responses to the Columbia Suicide Severity Rating Scale (C-SSRS), and
• Specific evaluation of blood pressure and pulse rate, clinical laboratory evaluations, and electrocardiogram (ECG) results.
|
|
| E.2.2 | Secondary objectives of the trial |
| To evaluate the effect of SPD489 on perception of health, quality of life, resource utilization, sexual functioning, depression symptoms, depression improvement, and amphetamine withdrawal symptoms. |
|
| E.2.3 | Trial contains a sub-study | No |
| E.3 | Principal inclusion criteria |
· Subject has completed 1 of the respective short-term antecedent SPD489 MDD studies and did not experience any clinically significant adverse events in the antecedent study that would preclude exposure to SPD489.
Subject was randomized as an inadequate responder in the antecedent study, or not randomized but continues to demonstrate residual depressive symptoms (MADRS total score of ≥5) at the end of the antecedent study, and in the Investigator’s opinion has the potential to benefit from adjunctive pharmacologic treatment.
|
|
| E.4 | Principal exclusion criteria |
Subject is considered a suicide risk in the opinion of the Investigator, has previously made a suicide attempt within the past 3 years, or is currently demonstrating active suicidal ideation.
Subject has any current co-morbid psychiatric disorder, either controlled with medications prohibited in this study or uncontrolled and associated with significant symptoms, which was not present or recognized at entry into the antecedent study and would have been exclusionary in the antecedent study.
A new onset or known history of serious cardiac problems that may place them at increased vulnerability to the sympathomimetic effects of a stimulant medication, a history of moderate to severe hypertension or an average (of 3 readings) resting sitting systolic blood pressure >139mmHg or an average (of 3 readings) diastolic blood pressure >89mmHg at study entry, or has a concurrent chronic or acute illness or unstable medical condition that may deteriorate that could confound the results of safety assessments, increase risk to the subject, or lead to difficulty complying with the protocol. |
