About this study
Recently published work has examined the effects of "atypical antipsychotics" in SSRI-treatment resistant patients. In these studies, patients with unipolar depression who were treated with SSRI's, but not responsive to treatment after 4 or more weeks, were supplemented with an atypical. The atypical antipsychotics were found to diminish depression symptoms, as well as benefit sleep quality.
We propose a similar study with Quetiapine XR, focusing on thinking processes, mood and anxiety. Patients with depression who are SSRI treatment resistant will be treated with Quetiapine. Cognition will be evaluated in the UBC Mood Disorders Clinic two times: first before Quetiapine addition, then after 8 weeks. Depression symptoms and other measurements will be done at the 9 time points: before Quetiapine, and each week after treatment has begun.
The primary purpose of this study is to evaluate the superiority of Quetiapine XR compared to placebo as augmentation therapy in treatment of anxiety and depressive symptoms in SSRI-nonresponsive unipolar patients. Secondarily, we would like to evaluate the safety and tolerability of quetiapine as augmentation therapy in SSRI-nonresponsive unipolar patients.
Read the detailed description
This is a double-blind, placebo-controlled study, in which patients will receive treatment of Quetiapine XR for 8 weeks. All patients will receive Quetiapine XR at an initial dose of 50mg/day to be increased incrementally (dose of 50mg/day 2 and 150mg/day 3) to achieve a target dose of 300 mg/day by day 4. Tablets will be self-administered early each night. Patient's results will be compared to their own baseline measurements, in a double-blind fashion.
Recruited patients will be evaluated at nine time points: a baseline prior to treatment (t = -7 days), an assessment one week after treatment has begun (t = 7 days), two weeks after (t = 14 days), three weeks after (t = 21 days), four weeks after (t = 28 days), five weeks after (t = 35 days), six weeks after (t = 42 days), seven weeks after (t = 49 days) and after 8 weeks of treatment (t = 56 days). Evaluation of cognition, mood and anxiety, will be done blind to which time point is being measured.
Basic blood work (fasting blood glucose, lipid screen including triglycerides, urea and electrolytes, cytokines and neuroimmune markers) will performed on each patient both at baseline (t = -7 days) and at t = 56 days. At 4 weeks, blood sample will be taken for fasting plasma glucose, HbA1c and transaminases. At baseline (-7 days) and completion (56 days) a battery of neurocognitive-impairment tests (see Appendix A) will be administered. In addition, the Hamilton Rating Scale for Depression (21-ITEM HAM-D GRID), Montgomery -Asberg Depression Rating Scale (MADRS), Hamilton Ratings Scale for Anxiety (HAM-A), the UKU Side Effect Rating Scale, and the Quality of Life Enjoyment and Satisfaction Questionnaire (Q-LES-Q) will also be assessed by the research team.

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing Quetiapine XR in people with Unipolar Depression, run by University of British Columbia at 1 site in Canada.
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 8 inclusion and 26 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 16 Nov 2010. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Canada. 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. 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 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
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?
Primary outcome will be measurements of cognitive function, determined both prior to treatment and after 8 weeks of treatment. (time frame: 8 weeks). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
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 16 Nov 2010.
