To determine if memantine in doses of 10 mg BID affects memory, cognition, and behavior in patients with Huntington's disease (HD).

Condition Intervention Phase
Huntington's Disease Drug: Memantine Phase 4

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Crossover Assignment
Masking: Quadruple (Participant, Care Provider, Investigator, Outcomes Assessor)

Further study details as provided by University of California, San Diego:

Primary Outcome Measures:
  • sensitive neuropsychological battery [ Time Frame: three months and six months of treatment ]

Secondary Outcome Measures:
  • behavioral and functional measures at three and six months of treatment [ Time Frame: three and six months of treatment ]

Estimated Enrollment: 60
Arms Assigned Interventions
Experimental: 1
Memantine 10 mg BID for three months
Drug: Memantine
10 mg BID x 3 months
Other Name: Namenda

Detailed Description:
Results of several published clinical trials suggest that memantine has a beneficial effect in dementing conditions, such as Alzheimer's disease; however, the effects of memantine on cognitive and behavioral function in HD are unknown. Our hypotheses are that HD patients who are administered memantine will show improved performance on psychometric tests of memory and executive functions in addition to behavior and that patients treated with memantine will show more improvement after six months than after three months of treatment.

Ages Eligible for Study:   18 Years and older   (Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Men or women aged 18 or older.
  • Diagnosis of HD with current complaints of memory or concentration difficulties.

  • Good general health with no additional diseases expected to interfere with the study.
  • Patient is not institutionalized.
  • Sufficient English skills to complete all testing without assistance of an English language interpreter.
  • Availability of a responsible caregiver who agrees to supervise administration of study drug, monitor the patient's compliance and adverse events, and accompany the patient to all clinic visits.

Exclusion Criteria:

  • 1. Any significant neurologic disease other than HD.
  • Severe psychotic features or other severe psychiatric problems within the last three months which could lead to difficulty complying with the protocol.
  • History of alcohol or substance abuse within the past two years (DSM IV criteria).
  • Any significant systemic illness or unstable medical condition which could lead to difficulty complying with the protocol.
  • History of MI in the past year or head trauma with loss of consciousness greater than 20 minutes.
  • Insulin-requiring diabetes.
  • Use of any FDA approved cognitive enhancing prescription medications or investigational drugs within 30 days.
  • Use of ginkgo biloba or DHEA within four weeks prior to baseline.
  • Use of narcotic analgesics within 4 weeks prior to baseline.
  • Patients who, in the investigator's opinion, would not comply with study procedures.
