E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The primary objective of this study is to determine if duloxetine 60-120 mg given orally once daily (QD) for 12 weeks will result in changes in amygdalae activation (average of right and left amygdalae) in response to implicit sad facial affect processing in subjects with MDD from Week 0 (Visit 2) (baseline/medication-free) to Week 12 (endpoint) when compared with healthy control subjects, as assessed by the change in the fMRI mean blood-oxygenation-level-dependent (BOLD) response. |
|
E.2.2 | Secondary objectives of the trial |
The secondary objectives of the study are:
• Neuroimaging Correlates: to examine if changes in (1) anterior cingulate activation and volume and (2)amygdalae activation and volume predict remission
(3) have diagnostic potential
• Molecular and Cellular Correlates:
4. translocation of Gsα from lipid rafts
5. Gsα-activated adenylyl cyclase
6. if change in Gsα-activated adenylyl cyclase correlates with translocation of Gsα from lipid rafts
7. Gsα localization and adenylyl cyclase
8. changes in BDNF, proBDNF and their receptors
9. changes in proinflammatory cytokines
• Clinical Measures and Outcome:
10. Change in clinical outcome from Week 0 to Week 12, as assessed by:
a. Remission
b. Response
11. change in the SDS
12. effects of treatment on other clinical outcomes
13. safety and tolerability during the 12-week open-label period

[3] Have signed the study ICD prior to any additional study procedures and after being informed of the study drug and procedures used in this study.

[19] Pregnant women, women who are breast-feeding, or women of childbearing potential who are not using a medically accepted means of contraception when engaging in sexual intercourse or have been surgically sterilized (for example, abstinence, intrauterine device, oral contraceptive, implant, Depo-Provera®, or barrier devices).
[20] Are judged by the investigator to have serious suicidal risk or risk of self-harm.
[21] Have a history of recurrent self-mutilation or self-harm.
[22] Have uncontrolled narrow-angle glaucoma.
[23] Have been diagnosed with an acute liver injury (such as hepatitis) or severe cirrhosis (Child-Pugh Class C).
[24] Have end-stage renal disease, a prior renal transplant, current renal dialysis, or severe renal impairment.

(Note: Subjects previously diagnosed with hyperthyroidism or hypothyroidism who have been treated on a stable dose of thyroid supplement for at least 3 months, have medically appropriate TSH concentrations and are clinically euthyroid, and are otherwise determined to be medically appropriate for study participation by the investigator are allowed.)
[26] Have had electroconvulsive therapy (ECT), transcranial magnetic stimulation (TMS), or vagus nerve stimulation (VNS) within the past year.

taking a CNS active medication that, in the opinion of the investigator, might
interfere with study participation (for example, is likely to require
hospitalization) or that, in the opinion of the investigator, might interfere with

diabetes).

E.5 End points |
E.5.1 | Primary end point(s) |
Anterior cingulate and amygdalae activation in response to implicit sad facial affect processing will be measured by fMRI measurement, the percentage signal change from baseline task (neutral faces) to experimental task (sad faces) in BOLD response. The primary analysis is to test the null hypothesis that the mean change in fMRI from baseline (Week 0) to Week 12 for MDD group equals that for the healthy control group - versus the alternative that the mean changes from baseline are not equal. The primary analysis will be conducted on the full analysis set. |
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
|
E.5.2 | Secondary end point(s) |
Evaluation of neuroimaging and its correlation with changes in biomarkers, changes in clinical data and measures of anxiety and depression. Safety will also be assessed by monitoring adverse events, clinical signs and suicide ideation. |
