A Phase 3 Trial of Lesion Network Mapping-Guided cTBS for Motor Recovery After Acute Ischemic Stroke (MASTRE-3)

9. juni 2026 opdateret af: Zi-Xiao Li, Beijing Tiantan Hospital

Lesion Network Mapping-Navigated Continuous Theta-Burst Stimulation for Motor Recovery in Acute Ischemic Stroke: A Randomized, Double-Blind, Sham-Controlled, Multicentre Phase 3 Trial: MASTRE-3

This Phase 3 study will evaluate whether lesion network mapping-guided continuous theta burst stimulation (cTBS) can improve recovery after acute ischemic stroke. The treatment uses each participant's brain imaging to identify individualized stimulation targets related to stroke symptoms. Participants will receive either active cTBS or a sham procedure in addition to standard stroke care. The study will assess whether this personalized brain stimulation approach improves functional recovery and is safe for patients after ischemic stroke.

Detaljeret beskrivelse

Acute ischemic stroke often leads to persistent motor impairment despite standard medical treatment and rehabilitation. The early post-stroke period may represent an important window for modulating brain network plasticity and promoting recovery. Continuous theta burst stimulation (cTBS), a patterned form of repetitive transcranial magnetic stimulation, can modulate cortical excitability over a short stimulation period and may support recovery when applied to clinically relevant motor networks.

This study evaluates a personalized neuromodulation approach based on lesion network mapping. For each participant, the acute infarct lesion is identified on clinical brain imaging and mapped to a reference functional connectome to estimate lesion-associated networks. Candidate stimulation targets are selected from symptom-relevant cortical network nodes, with consideration of accessibility, safety, and electric-field modeling. Neuronavigation is used to guide coil placement and maintain targeting accuracy.

Active treatment consists of lesion network mapping-guided cTBS delivered to individualized cortical targets using a figure-8 coil under neuronavigation. Sham stimulation follows the same imaging-based target selection, electric-field modeling, positioning, and procedural workflow, but uses a sham coil designed to mimic the sensory and acoustic features of stimulation without delivering a therapeutic magnetic field. This approach is intended to maintain blinding while isolating the effect of active stimulation.

This Phase 3 trial evaluates the efficacy and safety of individualized lesion network mapping-guided cTBS for recovery after acute ischemic stroke.

Våben og indgreb

Deltagergruppe / Arm
Intervention / Behandling
Eksperimentel: LNM-navigated cTBS group
Participants receive active lesion network mapping (LNM)-navigated continuous theta burst stimulation (cTBS).
Enhed: LNM-navigated cTBS
Individualized treatment targets are defined by outlining each patient's acute infarct lesion on MRI and projecting it onto a normative functional connectivity map to identify symptom-relevant network nodes within sensorimotor regions. Treatment is delivered over seven consecutive days using a figure-8 coil guided by neuronavigation. cTBS consists of 3-pulse bursts at 50 Hz, repeated at 5 Hz, for a total of 600 pulses over 40 seconds, delivered at 80% of the resting motor threshold (RMT).
Sham-komparator: Sham cTBS group
Participants receive sham LNM-navigated cTBS using procedures that mimic the active intervention.
Enhed: Sham cTBS
Sham stimulation follows the same MRI-based lesion mapping, target selection, neuronavigation workflow, coil positioning, timing, acoustic noise, and treatment course as the active group, but uses a sham figure-8 coil that mimics stimulation without generating a significant magnetic field. This design helps maintain blinding of participants and assessors while ensuring that no effective magnetic stimulation is delivered.
