Treatment resistant depression (TRD) is a frequent, debilitating condition mostly treated by antidepressants. Repeated magnetic transcranial stimulation (rTMS) has proven adjuvant efficacy in TRD in the acute phase of treatment with a very good tolerance and acceptability. Maintenance rTMS (mTMS) is a strategy consisting in adding regular single TMS sessions after response to an acute course in order to keep the benefit of initial treatment over several month or years. Demonstrating that rTMS is efficient to improve long-term prognosis and decrease economic burden would have a tremendous impact in clinical practice in psychiatry. Thus the investigator's aim is to analyze the long term impact of mTMS treatment on costs, but also quality of life and clinical issues.
TRD is associated with enormous social, economic, and personal costs. In literature, psychosocial and pharmacological interventions showed limited one year long-term efficacy in terms of relapse (only 10% of sustained remission at one-year follow-up actually) and quality of life due to refractoriness, observance and adverse effects. In the recent years the field of non-invasive brain stimulation became more mature with an increasing level of evidence reaching Level 1 for rTMS as curative treatment for depression in international guidelines. It is a safe and well tolerated treatment but with still high relapse rate at 6 month and one year (comparable to those former described for ECT). mTMS is a promising tool (as it was proven for ECT) to achieve sustained response several month after treatment in a significant proportion of patients. Little is known about its long-term economic and social benefit which is a crucial question given its time consuming nature. To date there is no large Randomized Clinical Trial (RCT) assessing the long-term health economic interest or adjuvant mTMS compared to treatment as usual (TAU) alone in unipolar TRD . This study is a double-blind randomized controlled trial aiming at determining a 12 month cost-utility analysis, according to collective perspective, of two different modalities of rTMS (systematic mTMS or curative rTMS in case of relapse) for TRD compared to TAU alone. The secondary aims are to describe 24 month cost-utility, longitudinal clinical issues in terms of mood and quality of life, prognosis factors, as well as TAU actual strategies in that population.

The frequency is : 2 sessions / week during 1 month, then 1 session / week during 2 months and finally 1 session every 2 weeks during 8 months. |

| Cost-utility ratio, according to collective perspective of rTMS use in TRD compared to conventional therapeutic approaches without active rTMS. | The utility will be measured by : Quality Adjusted Life Year (QALYs) as estimated from responses to the Euroqol-5 Dimensions (EQ-5D) health-related quality of life questionnaire. The questionnaire focuses on 5 dimensions: mobility, personal autonomy, current activities, pain/discomfort and anxiety/depression. For each of these dimensions, 3 answers are possible. The costs will be measured by the addition of the following costs: Drugs dispensing via Health insurance database "National system of information of the French health insurance" (SNIIRAM), hospitalizations, work stoppages and care consumption collected in a declarative patient questionnaire. | 12 months |

Sham rTMS will be used for the arm "without rTMS"
|
| rTMS course in case of relapse | Device | Same parameters as the initial course. The frequency is the same as the initial course: one daily session on 5 consecutive working days from Monday to Friday for at least 20 to 30 sessions over 4 to 6 weeks. |
|
| sham rTMS | Device | The sham stimulation consists of the identical rTMS procedure at the identical location using a commercial figure-eight sham coil. However, it does not produce the identical tactile sensation. A local electrical stimulation will be delivered with two disposable Electromyogram (EMG) electrodes using a transcutaneous electrical nerve stimulation (TENS) Stimulator. |
