Study Overview

Brief Summary

To establish the tolerability of treatment with 600, 1200 or 2400 mg per day of coenzyme Q10 in pre-manifest participants carrying the CAGn expansion for Huntington's Disease (HD).

Detailed Description

secondary objectives:

  1. To assess the change from baseline to 20 weeks on biomarkers of oxidative stress (8OHdG and 8OHrG) and DNA repair mechanisms (OGG1) in pre-manifest participants treated with 600, 1200 or 2400 mg per day of CoQ10.
  2. To assess the dose-response relationship between CoQ10 at dosages of 600, 1200 or 2400 mg per day and 8OHdG/8OHrG and OGG1.
  3. To assess the serum levels of CoQ10 at 600, 1200 or 2400 mg in pre-manifest participants and their relationship to 8OHdG/8OHrG and OGG1.
  4. To assess the feasibility of implementing a preventive therapeutic trial in a pre-manifest population.
  5. To assess the utility and stability of clinical measures of HD, social relations, behavior and employment in a pre-manifest sample enrolled in a treatment trial.

Inclusion Criteria

  • •Participants will be positive for the CAGn expansion in the Huntingtin gene (>36 repeats) and be pre-manifest by virtue of scoring 3 or less on diagnostic confidence level (Question 17 of the UHDRS)
  • •Participants will have received genetic testing prior to enrollment through a standard pre-manifest testing protocol.
  • •18 years of age or older.
  • •Concomitant medications are permitted with the exception of CoQ10, creatine > 5g/day and warfarin.

Exclusion Criteria

  • •History of intolerability to CoQ
  • •CoQ10 use within 60 days prior to randomization.
  • •Unstable medical or psychiatric illness;
  • •Substance abuse within one year of the baseline visit.
  • •Pregnancy, breastfeeding or lack of reliable contraception in women of childbearing age.
  • •Subjects with known allergy to FD&C #6 yellow food coloring.

Arms & Interventions

2400 mg per day of CoQ10

Experimental

All participants will start on a dosage of 600 mg/day in divided doses, increasing weekly by 600 mg/day to a maximum dosage of 2400 mg/day at week 4. Dosage should be stable from week 4 until week 20.

Intervention: CoQ10 (Drug)

1200 mg per day of CoQ10

Experimental

All participants will start on a dosage of 600 mg/day in divided doses, increasing weekly by 600 mg/day to a maximum dosage of 2400 mg/day at week 4. Dosage should be stable from week 4 until week 20.

Intervention: CoQ10 (Drug)

600 mg per day of CoQ10

Experimental

All participants will start on a dosage of 600 mg/day of CoQ10 in divided doses, increasing weekly by 600 mg/day to a maximum dosage of 2400 mg/day at week 4. Dosage should be stable from week 4 until week 20.

Intervention: CoQ10 (Drug)
