Prevention of Levodopa-induced Dyskinesias by Transcranial Static Magnetic Field Stimulation (tSMS)

October 10, 2018 updated by: Guglielmo Foffani, Fundación de investigación HM
This is a randomized sham-controlled double-blind study to test the hypothesis that transcranial static magnetic field stimulation (tSMS) of the motor cortex improves levodopa-induced dyskinesias in patients with Parkinson's disease. Half of the patients will receive real tSMS treatment, the other half will receive sham treatment (placebo).

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

14 years to 76 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Experimental: tSMS
30 min of tSMS, one session per day, for 9 days over 2 weeks
Device: tSMS
Transcranial static magnetic field stimulation (tSMS) is a non-invasive brain stimulation (NIBS) technique that decreases cortical excitability. Static magnetic fields suitable for tSMS are obtained with commercially available neodymium magnets. We will use a cylindrical neodymium magnet of 45 mm diameter and 30 mm of thickness, with a weight of 360 g (MAG45r; Neurek SL, Toledo, Spain), which will be applied with south polarity to the motor cortex, over the representational field of hand area contralateral to the more affected side of the body.
Other Names:
  • MAGmv1.0 with MAG45r, Neurek S.L. (Toledo, Spain)
Placebo Comparator: sham
30 min of sham, one session per day, for 9 days over 2 weeks
Device: sham
A non-magnetic metal cylinder, with the same size, weight and appearance of the magnet, will be used for sham stimulation (MAG45s; Neurek SL, Toledo, Spain).
Other Names:
  • MAGmv1.0 with MAG45s, Neurek S.L. (Toledo, Spain)

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Time Frame
Change from baseline of the maximal dyskinesia severity within 90min after levodopa intake, as measured by objective evaluation with the Unified Dyskinesia Rating Scale (UDysRS) one day after the end of treatment.
Time Frame: One day after the end of treatment compared to baseline
One day after the end of treatment compared to baseline

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Time Frame
Change from baseline of the maximal dyskinesia severity within 90min after levodopa intake, as measured by objective evaluation with the Unified Dyskinesia Rating Scale (UDysRS) one week after the end of treatment.
Time Frame: One week after the end of treatment compared to baseline
One week after the end of treatment compared to baseline
Dyskinesia severity evaluated for each body segment
Time Frame: Baseline, one day and one week after the end of treatment
Baseline, one day and one week after the end of treatment
Subjective evaluation of the treatment, as measured by the patient global impression of change (PGIC)
Time Frame: One day and one week after the end of treatment
One day and one week after the end of treatment
Change from baseline in motor symptoms, as measured by the MDS-UDPRS III scale
Time Frame: Baseline, one day and one week after the end of treatment
Baseline, one day and one week after the end of treatment
