About this study

PRECREST is a two phase protocol for Huntington's disease in which 60 premanifest and at-risk subjects will first be randomized into a double blind placebo controlled dose titration study bringing them to 30 grams daily or their highest tolerated dose. This phase will establish the highest tolerable doses in premanifest HD and permit the detection of toxicity and intolerability with attribution to active compound versus placebo, and enable a dose response assessment of biomarkers. In the second phase, all subjects will enter a year long open-label treatment on 30 grams daily (or their highest dose) of creatine to assess long term exposure to high dose creatine and its long term impact on various biomarkers.

Read the detailed description

Extensive evidence exists that neurodegeneration begins many years before HD can be diagnosed clinically. Therefore, it is most desirable to begin a neuroprotective therapy before or during this premanifest period with the aim of delaying onset, as well as slowing functional decline. Cellular energy depletion is present early in HD and can be ameliorated by creatine, which helps regenerate cellular ATP. Preclinical evidence for creatine's potential neuroprotective effects in animal models of HD has been well-documented. Before the clinical efficacy of creatine can be tested in premanifest HD, its long-term safety and tolerability must be assessed in these individuals and its ability to favorably modify biomarkers of HD should also be confirmed. A two phase protocol is proposed in which 60 premanifest and at-risk subjects will randomized into a double blind placebo controlled dose titration study bringing them to 30 grams daily or their highest tolerated dose. The placebo-controlled phase will permit the detection of toxicity and intolerability due to the active compound (creatine), and enable a dose response assessment of biomarkers. In the second phase, all subjects will enter a year long open-label treatment on 30 grams daily of creatine. This phase will maximize the subjects on active compound to promote recruitment and retention, to expand assessment of safety data on all subjects, and increase the power to detect and measure potential biological markers and any response to the active compound. The clinical impact of creatine will be assessed using the United Huntington's Disease Rating Scale. Safety and tolerability will be assessed by analyzing clinical and laboratory adverse events. Serum levels of creatine will be used to assess compliance and whether there is a relationship between bioavailability and response. 8OH2'dG and related markers will be assessed to determine whether creatine treatment can chronically suppress markers of energy depletion and oxidative injury and whether suppression correlates with slowing the progression of HD. Morphometric MRI will be used to determine whether creatine can slow brain atrophy in premanifest HD. This study will provide the pilot data needed to plan a future study to determine whether creatine can delay the onset or slow the progress of HD in premanifest individuals.

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Creatine monohydrate in people with Huntington Disease, run by Massachusetts General Hospital at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 1 inclusion and 2 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 10 Feb 2014. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Completion of Study (tolerability) (time frame: 18 Months). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT00592995, which also lists 14 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 10 Feb 2014.
