rTMS neurostimulation
Brief summary
This is a prospective clinical study evaluating the analgesic efficacy of a non-medicated treatment: repeated transcranial magnetic stimulation (rTMS) of the primary motor cortex in chronic migraine (\> 7 headache days per month and failure of at least 3 drug treatments). To this end, the study involves a double-blind, randomized, comparative experimental protocol against a sham control condition via 2 parallel groups comprising 60 patients each (N= 120 in total). Randomized block design with stratification by center and type of migraine (episodic or chronic). 5 rTMS sessions will be performed, with one stimulation session every 2 weeks. One group will receive active stimulation at each session (high-frequency stimulation of the left primary motor cortex, 2000 pulses per session, 80% of resting motor threshold) and the other group placebo stimulation (sham). Depending on the randomization group, rTMS sessions will be carried out by trained experimenters in the investigating center where the patient has been included. The study is multicentric, with five centers, four of which are in the Auvergne-Rhône-Alpes region. Data will be centralized at the Clermont-Ferrand University Hospital, and statistical analysis will be carried out by the Clermont-Ferrand University Hospital's Clinical Research and Innovation Department. Principal difference analysis (active vs sham) performed in ITT; missing data processed by multiple imputation.
Interventions
robot-guided high-frequency rTMS treatment (10hz - 5 sessions) of the primary motor cortex
sham robot-guided high-frequency rTMS treatment (10hz - 5 sessions) of the primary motor cortex

Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Variation of headaches days number per month | difference between the 4 weeks prior to initiation of treatment and the last 4 weeks post-treatment |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| variation in the number of headache (days per month) of at least 50% | between the 4 weeks prior to initiation of treatment and the last 4 weeks post-treatment | — |
| variation in the number of headache (days per month) of at least 30%. | between the 4 weeks prior to initiation of treatment and the last 4 weeks post-treatment | — |
| Patient Global Impression of Change (PGIC) | at week 12 | The score varies from 1 to 7 . A score of 1 means a better outcome and a score of 7 means a worse outcome |
Other
| Measure | Time frame | Description |
|---|---|---|
| Migraine Hypersensitivity Assessment Questionnaire (MHQ-8 scale, ex-MIGAL) score | Pre-treatment period (inclusion visit at W0 - 4) and at week 12 | This scale assesses the frequency and intensity of disturbances related to noise, light, skin stimulation, and odors during migraines |
| Improvement in Quality of life by migraine rescue medication intakes | Week0 - 4 to week0 -1 period compared to Week 9 - week 12 period | Improvement in quality of life will be assessed by use of migraine rescue medication before and after neurostimulation |
| Improvement in Quality of life by European Quality of Life 5 dimensions (EQ- 5D) scale score | At week 0, week 8 and week 12 | Improvement in quality of life will be assessed by the change of EQ-5D score |
| Improvement in Quality of life by relief subjective rate | At Week 2, week 4, week 6, week 8 and week 12 | A relief subjective rate since last neurostimulation will be asked to patient before each new neurostimulation session . A rate of 0% means no relief and 100% means a complete relief . |
| Improvement in Quality of life by anxiety and depression scores | At screening visit (Week 0 - 4) and week 12 | Anxiety and depression will be assessed by Hospital Anxiety and Depression Scale (HADS) |
| Improvement in Quality of life by resilience score | At screening visit (Week 0-4) and week 12 | Resilience score will be assessed by Connor-Davidson Resilience Scale (CD-RISC) in 25 items. The score ranges from 0 to 100 and a higher score means a higher resilience |
| Bang blinding index | week 0, week 2, week 4, week 6, week 8, week 12 | The patient will be asked what he thinks he received after the treatment, rTMS neuromodulation or sham neuromodulation |
| Brain activity (resting-state fMRI) | At screening visit (week 0- 4) and week 12 | MRI recording is routinely carried out before any rTMS session. This involves acquiring a 3D image of the participants' brains, which is necessary for targeting cortical area stimulated by rTMS using a neuronavigation system. Functional imaging (fMRI) in a resting state (i.e., without a 'resting-state' task) will allow to measure the basal state of activity and connectivity in the participants' brains. |
| Cortical excitability | At week 0 and week 12 | measured during rTMS motor threshold with paired pulse stimulation measurements |
| Evaluation of side effects | up to 4 weeks post-treatment (at week 12) | — |
| Changes in prognostic markers of response | At week 0, week 8 and week 12 | Following blood parameters will be assessed : Blood count, CRP, Venous glycemia, Insulin, prolactin, estradiol, FSH, LH, progesterone, testosterone, β-hCG, CGRP, VIP, PACAP-38, IL-6, IL-10, IL-17, IL-18, IL-1α, IL-1β, IL-21, IL-22, IL-23, IL-33, IL-35, CCL-20, IL-36β, IL-37, IL-38, IL-1Ra, TNFa, TGFβ, IL-2, INF-γ, T lymphocyte immunophenotyping (CD3, CD4, CD25, FoxP3, CTLA-4, ICOS, TNFR2, CD45, CD45RA, CD8, CD14, 4-1-BB, NKp46, CD19, CD197, CD39, CD73, GITR, TCRaβ, CD127, CD56, CD62L) |

| Improvement in Quality of life by catastrophizing score | At screening visit (Week 0-4) and week 12 | Catastrophism will be assessed by Pain Catastrophizing Scale (PCS) . Score ranges from 0 to 52. A higher score indicates a higher level of catastrophizing of pain. |
| Improvement in Quality of life by intensity and emotional experience of pain | At screening visit (week 0- 4) and week 12 | A visual analogue scale (VAS) ranging from 0 to 100 for pain intensity and affective experience will be used. |
| Variation of blood cytokine levels | Before (Week 0) and after treatment (Weeks 8 and 12) | Following cytokines levels will be assessed : IL-6, IL-10, IL-17, IL-18, IL-1α, IL-1β, IL-21, IL-22, IL-23, IL-33, IL-35, CCL-20, IL-36β, IL-37, IL-38, IL-1Ra, TNFa, TGFβ, IL-2, INF-γ |
