Trial Outcomes & Findings for Mexiletine in Sporadic Amyotrophic Lateral Sclerosis (NCT NCT02781454)

NCT ID: NCT02781454

Last Updated: 2019-12-05

Results Overview

The resting motor threshold (RMT) assessed from single pulse transcranial magnetic stimulation (TMS) measurements made before treatment, after 4 weeks of treatment, and then again after a 4 week washout, was used as the primary pharmacodynamic marker of cortical hyperexcitability. RMT is the stimulus intensity required to produce and maintain a 0.2 mV peak-to-peak motor evoked potential of the abductor pollicis brevis muscle by TMS. A smaller RMT is thought to suggest greater neuronal excitability.

Participant Flow

Subjects were enrolled at 9 Northeast ALS Consortium (NEALS) centers in the US. These NEALS centers were academic clinical research centers with established practices where sporadic ALS (sALS) patients are regularly seen and treated.

Within 21 days prior to treatment assignment, patients were screened for eligibility based on inclusion/exclusion criteria. Failure to meet any of these criteria at the time of this screening would result in exclusion from the study, and these patients would not be assigned to a treatment group.

Short-interval intracortical inhibition (SICI) is a measure of neuronal excitability measured by dual pulse TMS with a conditioned (80% of RMT) and test pulses (120% of RMT) to generate a stable MEP amplitude of 0.2 mV, averaged over interstimulus intervals of 1-7 ms. It is thought to reflect refractory cortical axons and subsequent resynchronization of cortico-cortical and corticomotoneuronal volleys or activation of non-GABAergic cortical inhibitory circuits (initial phase) and synaptic neurotransmission through GABAA receptors (second phase). The value for SICI thought to be maximally sensitive for detecting in changes in ALS subjects compared to controls is is derived by measuring the motor evoked potential amplitude (MEP) at an interstimulus interval of 3 ms (ISI 3 ms) and normalizing to the MEP amplitude at 120% of the resting motor threshold (MEP 120% RMT). A reduction in SICI reflecting greater excitability would generate a larger ratio of MEP ISI 3 ms/MEP 120% RMT.

Population: MEP at 120% RMT/peak CMAP

The motor evoked potential (MEP) amplitude is taken from single pulse transcranial magnetic stimulation (TMS) and reflects the density of corticomotoneuronal projections onto motor neurons and is affected by cortical hyperexcitability early in ALS where it is thought to be larger than age-matched controls and axonal degeneration later in the disease when it decreases in amplitude. The MEP is most reliable in assessing cortical motor neuronal preservation and excitability when normalized to the peak compound nerve action potential (CMAP) amplitude which reflects the integrity of peripheral motor nerve axons. It is also normalized here to 120% of the RMT to derive a ratio of MEP at 120% RMT/peak CMAP.

The cortical silent period (CSP) is recorded with single pulse TMS as a duration from the onset of the MEP response to resumption of voluntary electromyography activity with the patient performing a voluntary contraction, set to 30% of maximal voluntary contraction. A shorter CSP compared to controls would reflect greater excitability.

Population: strength duration time constant

The strength duration time constant (SDTC) is used in threshold tracking nerve axonal excitability studies and is interpreted as a measure of axonal excitability that is dependent upon the biophysical properties of the axonal membrane at the node of Ranvier, especially persistent sodium current. It is derived from the relationship between stimulus duration and intensity. A higher SDTC would reflect greater excitability of motor nerve axons.

Depolarizing threshold electrotonus (90-100 ms) (TEd 90-100 ms) is used in threshold tracking nerve axonal excitability studies in which long-lasting subthreshold depolarizing currents are generated, measured at 90-100 ms following the stimulus. This measure is associated with a decrease in the membrane excitability threshold due to opening of potassium channels on the axonal membrane. Intrinsic changes in axonal excitability properties, such as thought to occur in ALS, could possibly alter this measure, presumably by decreasing TEd 90-100 ms more substantially than normal.

Hyperpolarizing threshold electrotonus (90-100 ms) (TEh 90-100 ms) is used in threshold tracking nerve axonal excitability studies in which long-lasting subthreshold hyperpolarizing currents are generated, measured at 90-100 ms following the stimulus. This measure is associated with an increase in the membrane excitability threshold due to closure of potassium channels causing increased resistance of the internodal axonal membrane. Intrinsic changes in axonal excitability properties, such as thought to occur in ALS, could possibly alter this measure.

Superexcitability is a component of recovery cycle analysis assessing motor axonal excitability, employing threshold tracking nerve conduction study. It is a depolarizing afterpotential measured following a single supramaximal stimulus followed by a second smaller stimulus of variable intensity and reflects passive depolarization of the internodal axon.

Subexcitability is a component of recovery cycle analysis assessing motor axonal excitability, employing threshold tracking nerve conduction study. It is a late hyperpolarizing after potential measured following a single supramaximal stimulus followed by a second smaller stimulus of variable intensity and is related to the very slow turn-off of slow potassium channels.

The Amyotrophic Lateral Sclerosis Functional Rating Scale - Revised (ALSFRS-R) is an instrument for evaluating the functional status of patients with ALS that includes functions related to speech, swallowing, salivation, fine motor control, gross motor function, and respiration. The score is the sum of 12 items (range 0 to 48) with higher scores reflecting better function.
