STICODEP: tDCS as an add-on Treatment for Resistant Major Depression in Uni- or Bipolar Patients
Study Details
Study Description
Brief Summary
The aim is to investigate the effect of transcranial Direct Current Stimulation (tDCS) applied at the anodal left CDLPF of patients with resistant depression compared to patients treated with conventional therapy. The tDCS is used in add-on drug treatment in resistant depression stabilized for 4 weeks (antidepressant as SSRIs (Selective Serotonin Reuptake Inhibitors) or SNRIs (Serotonine-Norepinephrine Reuptake Inhibitors) for unipolar patients and lithium for bipolar patients). The delay of 4 weeks is a minimum to observe a non-response. Moreover, in term of ethical point of view, it's difficult to wait 6 to 8 weeks to observe the non-response to treatment.
This is a randomized 2-arm parallel, double blind study comparing 2 groups of 60 patients (48 unipolar plus 12 bipolar patients per group. Patients will be selected in the psychiatric department of the University Hospital of different centers and the two groups are matched for age (+/- 5 years), gender and depression diagnosis (unipolar vs bipolar).
After giving informed consent, patients will be evaluated by a psychiatrist using the Hamilton Depression Rating Scale (HDRS), Montgomery Asberg Depression Rating Scale (MADRS), the STAI and Beck Depression Inventory (BDI) and for bipolar patient only, by the Young Mania Rating Scale (YMRS). The complete assessment takes 50 minutes. A neuropsychologist assessment will be also realized during 20 minutes using the Crossing of Test (COT), the Trail Making Test (TMT), the Isaacs Set Test (IST) and the Cardebat fluency Task.
After locating the left DLPFC, treatment with active tDCS with a current of 2 mA or sham will be directed by 30-minute session. A psychometric assessment will be conducted again at the end of treatment week and 4, 12 and finally 24 weeks after stopping treatment. The neuropsychologist assessment will be conducted again 4 weeks after the end of treatment. Scales of comfort and acceptability will also be proposed to the patient to determine whether any gene is caused by this treatment.
These people will be recruited on a voluntary basis, after notification and consent in the 6 research centers. This study was conducted over a period of 36 months.
This study was supporting by a grant from the French Hospital Program of Clinical Reseach (PHRC N/2011-60-2011-A01074-37)

Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Active Comparator: active tDCS a group named G1 and treated by medication with SSRIs (Selective Serotonin Reuptake Inhibitors) or SNRIs (Serotonine-Norepinephrine Reuptake Inhibitors) for 48 unipolar patients or with Lithium for 12 bipolar patients stabilized for at least 4 months and 10 sessions of active anodal tDCS at 2 sessions per day (1 morning and 1 afternoon with a gap of 3h) for 5 days with an electric current 2 mA. |
Device: transcranial Direct Current Stimulation (tDCS) (Eldith DC NeuroConn Stimulator)
After locating the left DLPFC, ttt with active anodal tDCS with a current of 2 mA or sham over the left DLPFC will be directed by 30-minute session. Treatment will occur 2 sessions per day during 5 days per week. Subjects will be monitored during tDCS for any side effects or adverse events.

| Sham Comparator: sham tDCS a group named G2 and treated by medication with SSRIs or SNRIs for 48 unipolar patients or with Lithium for 12 bipolar patients stabilized for at least 4 months and sham tDCS. |
Device: transcranial Direct Current Stimulation (tDCS) (Eldith DC NeuroConn Stimulator)
After locating the left DLPFC, ttt with active anodal tDCS with a current of 2 mA or sham over the left DLPFC will be directed by 30-minute session. Treatment will occur 2 sessions per day during 5 days per week. Subjects will be monitored during tDCS for any side effects or adverse events.

Outcome Measures
Primary Outcome Measures
- change from baseline in HDRS-21 scale [baseline, 1 wk, 2 wk, 4wk, 12 wk, 24 wk]
The changes in HDRS-21 will constitute the major research outcome measure used to assess response to tDCS. Response to treatment is defined as a ≥ 50% reduction in the scores of the HDRS. Remission is defined as a HDRS score ≤ 8.
Secondary Outcome Measures
- Change from baseline in MADRS, BDI, HAMA, STAI, YMRS [baseline, 1 wk, 2 wk, 4wk, 12 wk, 24 wk]
Montgomery and Asberg Depression Rating Scale (MADRS) Beck Depression Inventory-13 (BDI) Subscores for anxiety depression scale from HDRS-21 State-Trait Anxiety Inventory (STAI) Young Mania Rating Scale (YMRS) : only for bipolar patient
- Change from baseline in COT, TMT, IST and Cardebat fluency task [baseline, 4wk]
Crossing of test (COT) Trail Making test (TMT) Isaacs Set Test (IST) Cardebat fluency task
