amphetamine and Multiple Sclerosis

amphetamine has been researched along with Multiple Sclerosis in 5 studies

Amphetamine: A powerful central nervous system stimulant and sympathomimetic. Amphetamine has multiple mechanisms of action including blocking uptake of adrenergics and dopamine, stimulation of release of monamines, and inhibiting monoamine oxidase. Amphetamine is also a drug of abuse and a psychotomimetic. The l- and the d,l-forms are included here. The l-form has less central nervous system activity but stronger cardiovascular effects. The d-form is DEXTROAMPHETAMINE.
1-phenylpropan-2-amine : A primary amine that is isopropylamine in which a hydrogen attached to one of the methyl groups has been replaced by a phenyl group.
amphetamine : A racemate comprising equimolar amounts of (R)-amphetamine (also known as levamphetamine or levoamphetamine) and (S)-amphetamine (also known as dexamfetamine or dextroamphetamine.

Multiple Sclerosis: An autoimmune disorder mainly affecting young adults and characterized by destruction of myelin in the central nervous system. Pathologic findings include multiple sharply demarcated areas of demyelination throughout the white matter of the central nervous system. Clinical manifestations include visual loss, extra-ocular movement disorders, paresthesias, loss of sensation, weakness, dysarthria, spasticity, ataxia, and bladder dysfunction. The usual pattern is one of recurrent attacks followed by partial recovery (see MULTIPLE SCLEROSIS, RELAPSING-REMITTING), but acute fulminating and chronic progressive forms (see MULTIPLE SCLEROSIS, CHRONIC PROGRESSIVE) also occur.

Trial Outcomes

Assess Depression Severity, as Measured by the Beck Depression Inventory-II (BDI-II)

The BDI-II is a 21-question multiple-choice self-report inventory test for measuring the severity of depression. Scores range from zero to 63; higher scores indicate greater depression. In order to account for all contributed data (even for those who did not complete the study but contributed some post-randomization data in the active study phase), the analyses include the BDI-II scores acquired within the active treatment phase (from baseline to week 24 visit). We then calculated and report the average change per week in the scores. (NCT02988401)
Timeframe: Up to week 24 visit

Change From Baseline in Cognitive Function as Assessed by the Brief Visuospatial Memory Test - Revised (BVMT-R) Delayed Recall

This is a visual, nonverbal test of learning and memory. Scores range from zero to 12; higher is better. In order to account for all contributed data (even for those who did not complete the study but contributed some post-randomization data in the active study phase), the analyses include the BVMT-R delayed recall scores acquired within the active treatment phase (from baseline to week 24 visit). We then calculated and report the average change per week in the score. (NCT02988401)

This is a verbal learning and memory test. Scores range from zero to 16; a higher number is better. In order to account for all contributed data (even for those who did not complete the study but contributed some post-randomization data in the active study phase), the primary analyses include the CVLT-II scores acquired within the active treatment phase (from baseline to week 24 visit). We then calculated and report the average change per week in the score. (NCT02988401)

Change From Baseline in Cognitive Function as Assessed by the Controlled Oral Word Association Test (COWAT)

This test measures phonemic fluency. The test scores the number of words a participant can provide that begin with a specified letter within one minute, such that scores range from zero (worst) to an infinite number (better). Total score is sum of three 60-second trials. In order to account for all contributed data (even for those who did not complete the study but contributed some post-randomization data in the active study phase), the primary analyses include the COWAT scores acquired within the active treatment phase (from baseline to week 24 visit). We then calculated and report the average change per week in the score. (NCT02988401)

Change From Baseline in Cognitive Function as Assessed by the Delis-Kaplan Executive Function System Sorting Test

This test measures executive functioning, concept formation, and cognitive flexibility. Scores range from zero to 16; higher is better. In order to account for all contributed data (even for those who did not complete the study but contributed some post-randomization data in the active study phase), the analyses include DKEFS correct sort scores acquired within the active treatment phase (from baseline to week 24 visit). We then calculated and report the average change per week in the score. (NCT02988401)

Change From Baseline in Cognitive Function as Assessed by the Judgement of Line Orientation Test (JLO)

Judgment of Line Orientation Test measures a person's ability to match the angle and orientation of lines in space. Scores range from zero to 30; higher is better. In order to account for all contributed data (even for those who did not complete the study but contributed some post-randomization data in the active study phase), the analyses include JLO data acquired within the active treatment phase (from baseline to week 24 visit). We then calculated and report the average change per week in the score. (NCT02988401)

Change in Cognitive Function as Assessed by the Rao-version of the Paced Auditory Serial Addition Test (PASAT)

"The Rao-version of the PASAT evaluates processing speed, working memory, and basic addition skills. Scores range from zero to 60; higher is better. Herein we present 3-second PASAT results (PASAT-3). In order to account for all contributed data (even for those who did not complete the study but contributed some post-randomization data in the active study phase), the analyses include PASAT-3 scores acquired within the active treatment phase (from baseline to week 24 visit). We then calculated and report the average change per week in the SDMT." (NCT02988401)

Change in Cognitive Function as Assessed by the Symbol Digit Modalities Test (SDMT)

This task will be performed at five study visits. The SDMT is one of the most commonly used tests to assess processing speed in the MS population and is included in the Minimal Assessment of Cognitive Function in MS (MACFIMS). Higher scores reflect a better outcome (range 0 to 110). In order to account for all contributed data (even for those who did not complete the study but contributed some post-randomization data in the active study phase), the primary analyses include the SDMTs acquired within the active treatment phase (from baseline to week 24 visit). We then calculated and report the average change per week in the SDMT. (NCT02988401)

Evaluation of How Overall Sleep Quality Impacts People With MS Using a Sleep Questionnaire (Pittsburgh Sleep Quality Index)

The sleep questionnaire asks subjects to report various aspects related to their sleep routine. Scores range from zero to 21; higher score indicates worse sleep quality. In order to account for all contributed data (even for those who did not complete the study but contributed some post-randomization data in the active study phase), the analyses include the PSQIs acquired within the active treatment phase (from baseline to week 24 visit). We then calculated and report the average change per week in the score. (NCT02988401)

Evaluation of Impact of Study Products on Health Related Quality of Life Using the Functional Assessment of Multiple Sclerosis Questionnaire (FAMS)

FAMS is a self-reported health-related quality-of-life instrument for people with multiple sclerosis. Subjects rate six quality-of-life domains: Mobility, Symptoms, Emotional well-being, General contentment, Thinking/fatigue, and Family/social well-being. Scores range from zero to 176; higher scores indicate better health-related quality of life. In order to account for all contributed data (even for those who did not complete the study but contributed some post-randomization data in the active study phase), the analyses include the FAMS scores acquired within the active treatment phase (from baseline to week 24 visit). We then calculated and report the average change per week in the score. (NCT02988401)

Number of Participants With Adverse Events Leading to Study Discontinuation

An adverse event will be defined as any occurrence or worsening of an undesirable or unintended sign, symptom (or abnormal laboratory test), or disease temporally associated with the use of a medicinal product or intervention, whether or not it is considered related to the product/intervention. We report overall adverse events in the relevant section. Here, we report adverse events that led to study discontinuation. (NCT02988401)
