Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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.

600 mg per day of CoQ10

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.

Group Type EXPERIMENTAL

CoQ10

Intervention Type DRUG

Capsules containing 300 mg of CoQ10 or matching placebo taken orally twice a day. All participant 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.

1200 mg per day of CoQ10

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.
