E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To evaluate the efficacy of TC-5214 compared with placebo as an adjunct to antidepressant (SSRI/SNRI) therapy in patients with MDD who exhibit an inadequate response to antidepressant therapy, as assessed by change in MADRS total score from randomization (Week 8) to end of treatment (Week 16).
Safety Objectives:
To evaluate the safety and tolerability of TC-5214 and placebo as an adjunct to an
antidepressant (SSRI/SNRI) in patients with MDD who exhibit an inadequate response to antidepressant therapy. |
|
E.2.2 | Secondary objectives of the trial |
To evaluate the efficacy of TC-5214 compared with placebo as an adjunct to an antidepressant (SSRI/SNRI) in patients with MDD who exhibit an inadequate response to antidepressant therapy as assessed by depressive symptoms, clinical global outcome regarding severity and improvement, and anxiety, and as assessed by patient-reported outcomes (PROs) regarding functional impairment, overall quality of life, and severity of depressive symptoms.
To investigate pharmacokinetic (PK) properties of TC-5214 in patients with MDD
using a population PK analysis methodology. SSRI/SNRI will be quantified in the
open-label ADT period. These results will be reported separately from the primary
and other secondary objectives.
Change in overall quality of life and satisfaction from randomization (Week 8) to
end of treatment in Q-LES-Q-SF, items 15 and 16.
Change in health-related quality of life as measured by the EuroQol VAS and
5 dimensions (EQ-5D) from randomization to end of treatment. |
|
E.2.3 | Trial contains a sub-study | Yes |
E.2.3.1 | Full title, date and version of each sub-study and their related objectives |
Pharmacogenetics Research, appendix version 1.0, dated 30 March 2011
AstraZeneca intends to perform genetic research in the TC-5214 clinical development
program to explore how genetic variations may affect the clinical parameters associated with TC-5214 and/or agents used in combination or as comparators. Collection of DNA samples from populations with well described clinical characteristics may lead to improvements in the design and interpretation of clinical trials and, possibly, to genetically guided treatment strategies. Studies may also be performed on the underlying genetic contribution to MDD.
The objective of this research is to collect and store DNA for future exploratory research into genes/genetic variation that may influence response (ie, distribution, safety, tolerability and efficacy) to TC-5214 and/or co-medication. Investigations into the genetic factors influencing disease (depression) may also be undertaken.

E.3 | Principal inclusion criteria |
Provision of signed and dated informed consent before initiation of any study-related procedures.

Outpatient status at enrollment and randomization. |
|
E.4 | Principal exclusion criteria |
Patients with a lifetime history of bipolar disorder, psychotic disorder or post-traumatic stress disorder.
Patients with a history of suicide attempts in the past year and/or seen by the investigator as having a signficant history of risk of suicide or homicide.
History of renal insufficiency or impairment or conditions that could affect absorption or metabolism of investigational product. |

E.5 End points |
E.5.1 | Primary end point(s) |
Primary efficacy variable: Change in the Montgomery-Asberg Depression Rating Scale (MADRS) total score from randomization (Week 8) to end of treatment (Week 16). |
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
Will be scored at Weeks 8 (baseline), 9, 10, 12, 14 and 16. |
|
E.5.2 | Secondary end point(s) |
Changes in clinician-rated symptoms as assessed by MADRS, Hamilton Rating Scale for Depression (HAM-D), Clinical Global Impression Severity (CGI-S), Clinical Global Impression Improvement (CGI-I) and Hamilton Anxiety Scale (HAM-A).
Changes in patient-reported outcomes as assessed by Sheehan Disability Scale, and Quality of Life Enjoyment and Satisfaction Questionnaire-Short Form.
AEs, SAEs, change in physical exam results and vital signs, laboratory tests and ECG, C-SSRS, BARS and AIMS, CSFQ and DESS will be assessed as a measure of safety and tolerability. |
|
E.5.2.1 | Timepoint(s) of evaluation of this end point |
MADRS and CGI will be scored at Weeks 8 (baseline), 9, 10, 12, 14 and 16; HAM-D and HAM-A will be scored at Weeks 8 (baseline) and 16.
Will be analysed at Weeks 8, 12 and 16 for SDS and Weeks 8 and 16 for Q-LES-Q-SF.
Will be collected during the whole study period. Unsolicited SAEs will be collected for 30 days post last study treatment. |
