Purpose
The goals of this trial are to determine if coenzyme Q10 is effective in slowing
the worsening symptoms of Huntington's disease and to learn about the safety and
acceptability of long-term coenzyme Q10 use by determining its effects on people
with Huntington's disease.

Arms
Assigned Interventions
A: Active Comparator
Randomized to active treatment (coenzyme Q10 2400 mg/day)
Drug: coenzyme Q10
4 - 300 mg CoQ chewable wafers taken orally twice a day
B: Placebo Comparator
Randomized to placebo
Other: placebo
an inactive substance Detailed Description:
Huntington's disease (HD) is a slowly progressive disorder that devastates the
lives of those affected and their families. There are no treatments that slow
the progression of HD, only mildly effective symptomatic therapies are
available.
The purpose of this trial is to find out if coenzyme Q10 (CoQ) is effective in
slowing the worsening symptoms of HD. In this study, researchers also will learn
about the safety and acceptability of long-term CoQ use by determining its
effects on people with HD.
Participants in this trial will be randomly chosen to one of two groups. Group 1
will receive CoQ (2400 mg/day), and group 2 will receive a placebo (an inactive
substance). Researchers will compare the change in total functional capacity
(TFC)¡ªa measure of functional disability¡ªin the two groups. The TFC is a valid
and reliable measure of disease progression and is particularly responsive to
change in the early and mid-stages of HD. Researchers will also compare the
changes in other components of the Unified Huntington's Disease Rating Scale '99
(UHDRS) including: the total motor score, total behavioral frequency score,
total behavior frequency X severity score, verbal fluency test, symbol digit
modalities test, Stroop, interference test, functional checklist, and
independence scale scores. The groups will also be compared with respect to
tolerability, adverse events, vital signs, and laboratory test results as
measures of safety.
Eligibility
Ages Eligible for Study:
16 Years and older
Genders Eligible for Study:
Both
Accepts Healthy Volunteers:
No
Criteria
Inclusion Criteria:
To be eligible for enrollment into this study, subjects must meet the following
eligibility criteria within 28 days prior to randomization:
Subjects must have clinical features of HD and a confirmed family history of HD,
OR a CAG repeat expansion ¡Ý 36.
TFC > 9.
Must be ambulatory and not require skilled nursing care.
Age ¡Ý 16 years.
Women must not be able to become pregnant (e.g., post menopausal, surgically
sterile or using adequate birth control methods for the duration of the study).
If psychotropic medications are taken (e.g., anxiolytics, hypnotics,
benzodiazepines, antidepressants), they must be at a stable dosage for four
weeks prior to randomization and should be maintained at a constant dosage
throughout the study, as possible. Any changes to these medications mandated by
clinical conditions will be systematically recorded and the subject will be
permitted to remain in the trial.
Able to give informed consent and comply with trial procedures
Able to take oral medication.
Able to identify an informant or caregiver who will be willing and able to
supervise the daily dosing of study medications and to maintain control of study
medications in the home.
A designated individual will be identified by the subject to participate in the
ongoing consent process should the subject's cognitive capacity to consent
become compromised during participation in the study.
Exclusion Criteria:
History or known sensitivity of intolerability to CoQ.
Exposure to any investigational drug within 30 days of the Baseline visit.
Clinical evidence of unstable medical illness in the investigator's judgment.
Unstable psychiatric illness defined as psychosis (hallucinations or delusions),
untreated major depression or suicidal ideation within 90 days of the Baseline
visit.
Substance (alcohol or drug) abuse within one year of the Baseline visit.
Women who are pregnant or breastfeeding.
Use of supplemental coenzyme Q10 within 120 days prior to the Baseline visit
Clinically serious abnormalities in the screening laboratory studies (Screening
creatinine greater than 2.0, alanine aminotransferase (ALT) or total bilirubin
greater than 3 times the upper limit of normal, absolute neutrophil count of
¡Ü1000/ul, platelet concentration of <100,000/ul,> 1.5 time upper limit of
normal).
Known allergy to FD&C yellow #5 or any other ingredient in the study drug
(active and placebo)
