Safety and Efficacy of Fenofibrate as a Treatment for Huntington's Disease

September 3, 2023 updated by: Leslie Thompson, University of California, Irvine

A Phase IIa, Randomized, Double-blind, Placebo-controlled Study of the Safety and Efficacy of Fenofibrate as a Treatment for Huntington's Disease

The purpose of this research study is to study the safety and efficacy of fenofibrate, an FDA-approved drug for high cholesterol and/or elevated triglycerides (fats), as a treatment for Huntington's disease (HD). Subjects who meet the entry criteria will be randomized (3:1) to either 145mg of fenofibrate or placebo.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.
Interventional

Enrollment (Actual)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

14 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

  • Are able to give informed consent,
  • Have good overall health status with no known problems anticipated over the course of the trial,
  • Have a diagnosis of HD supported by positive gene test within the past 6 months.

Exclusion Criteria:

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Change in PGC-1alpha RNA Expression
Time Frame: Baseline compared to 3 and 6 months.
Change in PGC-1alpha RNA expression from Baseline, Month 3 and Month 6
Baseline compared to 3 and 6 months.
Change in PGC-1alpha Protein Abundance.
Time Frame: Baseline compared to 3 and 6 months.
Mean change in PGC-1alpha protein abundance.
Baseline compared to 3 and 6 months.

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Change in Fenofibric Acid Level.
Time Frame: Baseline to 3 and 6 months.
Change in Fenofibric acid abundance from Baseline to 3 and 6 months.
