NCT06681610

Brief Summary

The goal of this clinical trial is to assess the efficacy of TPS of the motor cortex on biomarkers and clinical endpoints in patients with ALS. The main questions it aims to answer are:

  • Stage 1: Is there a change in the short intracortical inhibition (SICI) of the motor cortex from baseline to week 8?
  • Stage 2: Is there a change from baseline to month 6 in the ALS functional rating scale-revised (ALSFRS-R) total score? In stage 2, researchers will compare the group receiving the stimulation vs the group receiving a sham stimulation to see if there is a difference in motor cortex activity and in the ALSFRS-R score Participants will receive either:
  • the TPS treatment
  • a sham TPS treatment

Outcome Measures

Primary Outcomes (2)

  • Change in the short intracortical inhibition (SICI) of the motor cortex from baseline to week 8.

    baseline to week 8

  • Change from baseline to month 6 in the ALS functional rating scale-revised (ALSFRS-R) total score

    The ALS Functional Rating Scale-Revised Each function is scored from 4 (normal) to 0 (no ability), with a maximum total score of 48 and a minimum total score of 0. Higher scores mean a better outcome.

    baseline to week 24

Secondary Outcomes (8)

  • Change plasma neurofilament light chain (NfL) levels

    baseline to week 4 and 8

  • Changes in muscle strength, assessed by the Medical Research Council (MRC) sum score

    baseline to week 4 and 8

  • Changes in hand-held dynamometry

    baseline to week 8

  • Differences (treated vs sham) and change in the slow vital capacity (SVC)

    from baseline to month 6

  • Differences (treated vs sham) and change in plasma NfL levels

    baseline to month 6

  • +3 more secondary outcomes

Other Outcomes (7)

  • Change in biomarker SOD1 Levels in nEVs from Plasma

    baseline to week 4 and 8

  • Change in biomarker Ataxin 2 Levels in nEVs from Plasma

    baseline to week 4 and 8

  • Change in biomarker C9orf72 Levels in nEVs from Plasma

    baseline to week 4 and 8

  • +4 more other outcomes

Study Arms (2)

TPS

EXPERIMENTAL

The stimulation will be 20 min duration as indicated in the CE mark approval. Each session involves 6,000 pulses in the hand region of the motor cortex with 3,000 on each side of the brain. The system uses a low energy flux density maximum of 0.25 mJ/mm2 accordingly with EMA and FDA guidelines (high energy is defined as \> 0.5 mJ/mm2). The standard therapy involves 6 sessions in 2 weeks as indicated in the CE mark.

Device: Transcranial Pulse Stimulation

sham

SHAM COMPARATOR

The transcranial pulse stimulation with the same device and the same protocol uses a membrane on the device that blocks the sound waves. Participants' motor cortex is not stimulated.

Device: Transcranial Pulse Stimulation

Interventions

low intensity shock-waves stimulation of the motor cortex, bilateral

TPSsham
