carbamazepine and Huntington Disease

carbamazepine has been researched along with Huntington Disease in 9 studies

Carbamazepine: A dibenzazepine that acts as a sodium channel blocker. It is used as an anticonvulsant for the treatment of grand mal and psychomotor or focal SEIZURES. It may also be used in the management of BIPOLAR DISORDER, and has analgesic properties.
carbamazepine : A dibenzoazepine that is 5H-dibenzo[b,f]azepine carrying a carbamoyl substituent at the azepine nitrogen, used as an anticonvulsant.

Huntington Disease: A familial disorder inherited as an autosomal dominant trait and characterized by the onset of progressive CHOREA and DEMENTIA in the fourth or fifth decade of life. Common initial manifestations include paranoia; poor impulse control; DEPRESSION; HALLUCINATIONS; and DELUSIONS. Eventually intellectual impairment; loss of fine motor control; ATHETOSIS; and diffuse chorea involving axial and limb musculature develops, leading to a vegetative state within 10-15 years of disease onset. The juvenile variant has a more fulminant course including SEIZURES; ATAXIA; dementia; and chorea. (From Adams et al., Principles of Neurology, 6th ed, pp1060-4)

Trial Overview

Trial Outcomes

Executive Function Composite Score Comparing Visit 2 (Week 0) to Visits 5 (Week 12) & 6 (Week 15) for the Citalopram Cohort Versus Placebo Cohort.

Full Scale Name: The Executive Composite Score (ECS). Definition: Subscales were averaged to compute this composite total score. The ECS is the weighted average of performance on 6 subtests of executive function, including (1) the Controlled Oral Word Association Test, (2) Symbol Digit Modalities test; (3) Stroop Color Word Test (Interference Trial), (4) Trail Making test (Part B), (5) Letter-Number Sequencing, and (6) Animal Naming. Construct Measured: Thinking tasks involving planning, working memory, attention, problem solving, verbal reasoning, inhibition, mental flexibility, and task switching. ECS Scale Range: The ECS score ranges from -5 to +5 on a standardized (Z) score scale, where lower scores indicate poorer performance on executive functioning tasks. Change Calculation Details: Compares change in executive functioning performance from visit 2 (week 0) to the weighted average of visits 5 (week 12) & 6 (week 15) for the citalopram versus placebo cohort. (NCT00271596)
Timeframe: after 15 weeks of treatment

Hamilton Rating Scale for Depression Comparing Screening (Intake Visit) to Visit 6 (Week 15) for the Citalopram Cohort Versus Placebo Cohort

Full Scale Name: Hamilton Rating Scale for Depression (HAM-D). Definition: The Hamilton Rating Scale for Depression is a clinician-administered multiple item questionnaire used to provide an indication of depression. Construct Measured: Depression. HAM-D Score Range: Raw scores may range from 0 to 54, where higher scores indicate worsening mood. Change Calculation Details: Compares change in mood from screening (intake visit) to visit 6 (week 15) for the citalopram versus placebo cohort. (NCT00271596)
Timeframe: after 15 weeks of treatment

Letter Number Sequencing Score Comparing Visit 2 (Week 0) to Visits 5 (Week 12) & 6 (Week 15) for the Citalopram Cohort Versus Placebo Cohort

Full Scale Name: Letter Number Sequencing (LNS) subtest from the Wechsler Adult Intelligence Scale (WAIS) third edition. Definition: LNS is a task that requires the reordering of an initially unordered set of letters and numbers. Construct Measured: Working memory. LNS Score Range: Raw scores may range from 0 to 21, where lower scores indicate poorer performance in working memory. Change Calculation Details: Compares change in working memory performance from visit 2 (week 0) to the weighted average of visits 5 (week 12) & 6 (week 15) for the citalopram versus placebo cohort. (NCT00271596)
Timeframe: after 15 weeks of treatment

Semantic Fluency Score Comparing Visit 2 (Week 0) to Visits 5 (Week 12) & 6 (Week 15) for the Citalopram Cohort Versus Placebo Cohort

Semantic Fluency Score. Definition: The Semantic Fluency Score is the number of words a person can produce given a category, including naming (1) Animal names, (2) Fruit names, (3) Boy names, (4) Girl names, and (5) Vegetable names. Construct Measured: Working memory and verbal initiation. Scale Range: The Semantic Fluency Score ranges from -5 to +5 on a standardized (Z) score scale, where lower scores indicate poorer performance on working memory tasks. Change Calculation Details: Compares change in working memory performance from visit 2 (week 0) where patients named fruit names to the weighted average of visits 5 (week 12) & 6 (week 15) where patients named girl names and vegetable names respectively for the citalopram versus placebo cohort. (NCT00271596)
Timeframe: after 15 weeks of treatment

Stroop Interference Score Comparing Visit 2 (Week 0) to Visits 5 (Week 12) & 6 (Week 15) for the Citalopram Cohort Versus Placebo Cohort

"Full Scale Name: Stroop Interference subtest from The Stroop Color and Word Test. Definition: Participants are asked to name the ink color in which a word is printed when the word itself (which is irrelevant to the task) is the name of a different color rather than the same color. For example, participants may be asked to say red to the word blue printed in red ink. Constructs Measured: Selective attention, response inhibition, cognitive flexibility, and processing speed. Scale Range: The Stroop Interference score ranges from -5 to +5 on a standardized (Z) score scale, where lower scores indicate poorer performance. Change Calculation Details: Compares change in attention and processing speed performance from visit 2 (week 0) to the weighted average of visits 5 (week 12) and 6 (week 15) for the citalopram versus placebo cohort." (NCT00271596)
Timeframe: after 15 weeks of treatment

Subgroup Analysis of the Hamilton Depression Rating Scale Comparing Screening (Intake Visit) to Visit 6 (Week 15) for the Citalopram Cohort Versus Placebo Cohort

Full Scale Name: Hamilton Rating Scale for Depression (HAM-D). Definition: The Hamilton Rating Scale for Depression is a clinician-administered multiple item questionnaire used to provide an indication of depression. Construct Measured: Depression. HAM-D Score Range: Raw scores may range from 0 to 54, where higher scores indicate worsening mood. Change Calculation Details: This analysis was restricted to a subgroup and, accordingly, does not reflect the total number of participants as reported in the Participant Flow. This analysis compares change in mood from screening (intake visit) to visit 6 (week 15) for the citalopram versus placebo cohort. (NCT00271596)

Construct Measured: Attention, processing speed, and working memory. SDMT Scale Range: Raw scores may range from 0 to 110, where lower scores indicate poorer performance. Change Calculation Details: Compares change in performance from visit 2 (week 0) to the weighted average of visits 5 (week 12) & 6 (week 15) for the citalopram versus placebo cohort. (NCT00271596)

Constructs Measured: Attention, set shifting, and processing speed. Scale range: The TMT-B score ranges from -5 to +5 on a standardized (Z) score scale, where lower scores indicate poorer performance. Change Calculation Details: Compares change in attention and processing speed performance from visit 2 (week 0) to the weighted average of visits 5 (week 12) and 6 (week 15) for the citalopram versus placebo cohort."
