Brief Summary

The CoMPACT trial is a randomized double-blinded sham-controlled study aimed at testing a novel accelerated and personalized transcranial Magnetic Stimulation (TMS) treatment for patients with Treatment Resistant Depression (TRD). CoMPACT consists of 25 sessions of intermittent theta-burst transcranial stimulation (iTBS) consisting of high inter-pulse frequency administered five times daily over five consecutive days. The trial will include 78 patients with TRD who will be randomly assigned to one of three groups:

  • Group 1: Real CoMPACT targeting the left dorsolateral prefrontal cortex (DLPFC).
  • Group 2: Real CoMPACT targeting a novel site, the left inferior parietal lobule (IPL).
  • Group 3: Sham CoMPACT targeting the left DLPFC (50%, Group 3a) or left IPL (50%, Group 3b). The hypothesis is that real prefrontal or parietal CoMPACT targeting will significantly alleviate depression symptoms compared to sham targeting, without compromising safety, feasibility, or tolerability. The trial incorporates a personalized approach, using electrical field (E-field) modeling based on individual structural brain scans to tailor and standardize iTBS, ensuring accurate targeting of cortical volume and consistent induced electrical field strength. To delineate the treatment mechanism of action at the brain network level, multi brain mapping models will be implemented. Electroencephalography (EEG) records of spontaneous and TMS-evoked electrical brain activity will be obtained before, during, and after iTBS sessions to understand how the high frequency burst protocol functionally engages the stimulated cortex. Structural and functional brain MRI before and after the treatment will be used to study changes in depression-related brain networks. This will offer key insights into how CoMPACT affects depression-related brain networks and may identify neuroimaging markers for predicting treatment response, and thus informing future TBS treatments for TRD.

Outcome Measures

Primary Outcomes (1)

  • Change in the Hamilton Rating Scale for Depression-6 (HDS-6) Score

    The HDS-6 total score reflects the severity of depression, ranging from 0 to 24, with higher scores indicating more severe symptoms. 0-6 = normal, 7-8= mild depression, 9-11 = moderate depression, 12-22 = severe to very severe depression. A 3-point change is considered to be clinically significant, which is a very conservative criterion.

    1) Baseline T0: (1 (+1) week before intervention. 2) Before the first iTBS session on the first day of intervention week. 3) A day after end of intervention (+2 days). 4) Follow-up (T2): 4 weeks after end of intervention.

Secondary Outcomes (16)

  • Change in the Hamilton Rating Scale for Depression-17 (HDS-17) Score

    1) Baseline T0: (1 (+1) week before intervention. 2) Before the first iTBS session on the first day of intervention week. 3) A day after end of intervention (+2 days) . 4) Follow-up (T2): 4 weeks after end of intervention.

  • Change in the WHO-5 Well-being Index (WHO-5) score

    1) Baseline T0: (1 (+1) week before intervention. 2) Postintervention (T1): 3 (+/-2 ) days after end of intervention. 3) Follow-up (T2): 4 weeks after end of intervention.

  • Change Snaith-Hamilton Pleasure Scale (SHAPS) score

    1) Baseline T0: (1 (+1) week before intervention. 2) Postintervention (T1): 3 (+/-2 ) days after end of intervention. 3) Follow-up (T2): 4 weeks after end of intervention.

  • Change in Overall Anxiety Severity and Impairment Scale (OASIS) score

    1) Baseline T0: (1 (+1) week before intervention. 2) Postintervention (T1): 3 (+/-2 ) days after end of intervention. 3) Follow-up (T2): 4 weeks after end of intervention.

  • Visual analogue mood scale (VAMS)

    1) Baseline T0: (1 (+1) week before intervention. 2) On every day of intervention. 3) Postintervention (T1): 3 (+/-2 ) days after end of intervention. 4) Follow-up (T2): 4 weeks after end of intervention.

  • +11 more secondary outcomes

Other Outcomes (7)

  • Changes in magnetic resonance imaging (MRI) from baseline to postintervention

    1) Baseline T0: (1 (+1) week before intervention. 2) Postintervention (T1): 3 (+/-2 ) days after end of intervention.

Study Arms (3)

Real intermittent theta burst stimulatio (iTBS) of the dorsolateral prefrontal cortex (DLPFC)

ACTIVE COMPARATOR

Real intermittent theta burst stimulation (iTBS) of the left inferior parietal lobule (IPL)

ACTIVE COMPARATOR
Device: Device: MagVenture XP Orange Stimulator and active side of MagVenture COOL-B65 coil.

Sham Comparator: Sham stimulation to either left IPL (50%) or left DLPFC (50%)

SHAM COMPARATOR

Interventions

Intermittent theta burst stimulation (iTBS) targeting the left dorsolateral prefrontal cortex (DLPFC) will be administered over five consecutive days. On each intervention day, patients will undergo five high frequency iTBS sessions (each lasting approximately 10 minutes, excluding preparation) with about 50 minutes of rest between sessions. Each iTBS session delivers 1,800 pulses, resulting in a total of 25 sessions and 45,000 pulses over the course of a standard work week.

Real intermittent theta burst stimulatio (iTBS) of the dorsolateral prefrontal cortex (DLPFC)

Intermittent theta burst stimulation (iTBS) targeting the left inferior parietal lobule (IPL) will be administered over five consecutive days using the stimulation pattern described in the active DLPFC arm.

Real intermittent theta burst stimulation (iTBS) of the left inferior parietal lobule (IPL)

Device: Sham stimulation of the left DLPFC or IPL will be administered using the same stimulation duration and repetition as the active iTBS. To match the subjective experience of iTBS, the sham CoMPACT uses a dedicated (Active/Placebo) stimulation coil that has both active and sham functions, generating the same sound level regardless of the type of stimulation.

Sham Comparator: Sham stimulation to either left IPL (50%) or left DLPFC (50%)
