About this study
Official title: A Phase 2, Multicenter, Double- Blind, Parallel-group, Randomized, Placebo-controlled, Forced-dose Titration, Dose-ranging Efficacy and Safety Study of SPD489 in Combination With an Antidepressant in the Treatment of Adults With Major Depressive Disorder With Inadequate Response to Prospective Treatment With an Antidepressant
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. 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 SPD489 help patients with depression who are also 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?
- Conditions
- Major Depressive Disorder
- Being tested
- Antidepressant + SPD489 (Lisdexamfetamine dimesylate) 10 mg, Antidepressant + SPD489 (Lisdexamfetamine dimesylate) 30 mg, Antidepressant + SPD489 (Lisdexamfetamine dimesylate) 50 mg, Antidepressant + SPD489 (Lisdexamfetamine dimesylate) 70 mg, Antidepressant + Placebo

Questions about this trial
What is this clinical trial studying?
A Phase 2 study testing Antidepressant + SPD489 (Lisdexamfetamine dimesylate) 10 mg, Antidepressant + SPD489 (Lisdexamfetamine dimesylate) 30 mg and Antidepressant + SPD489 (Lisdexamfetamine dimesylate) 50 mg in people with Major Depressive Disorder, run by Shire at 82 sites in 5 countries.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 7 inclusion and 25 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 9 Jun 2021. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 82 sites in United States, Chile, Argentina, Australia, United Kingdom. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
Yes. Results are posted in the registry (first posted 19 Feb 2015). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Change in Montgomery-Ǻsberg Depression Rating Scale (MADRS) Total Score From Augmentation Baseline (Week 8) to Week 16 (Double-blind Phase, Dose Response Evaluable Set) (time frame: Augmentation Baseline (Week 8) to Week 16). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT01435759, which also lists 1 linked publication.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 9 Jun 2021.
