| NCT03792672 | A Study to Evaluate Central Nervous System (CNS) Pharmacodynamic Activity of TAK-653 in Healthy Participants Using Transcranial Magnetic Stimulation (TMS) | PHASE1 | COMPLETED | 24 | — | — | Feb 11, 2019 | Jun 18, 2019 | Mar 19, 2021 | 1 | Netherlands |
TMS was a neurophysiologic test for assessing upper motor neuron function. TMS was a noninvasive neuro stimulation method involving the application of brief magnetic pulses to the skull, based on the principles of electromagnetic induction, create an orthogonal electric current that can be sufficient to depolarize neurons and activate neuronal circuits. Single-pulse TMS was used to determine peak-to-peak amplitude of MEP at a stimulation intensity of 120 percent (%) of baseline resting motor threshold (rMT). rMT was defined as the minimum stimulus intensity to evoke an MEP. Change in peak-to peak amplitude of MEP was be assessed by TMS after treatment with 0.5 mg or 6 mg of TAK-653 versus (vs.) matched oral placebo.
The rMT was defined as the minimum stimulus intensity to evoke an MEP. Single-pulse TMS was used to determine rMT. A lower rMT value indicated greater neuronal excitability.
