About this study

Participants wanted for study of mevalonate kinase deficiency (MKD), mevalonic aciduria, or hyperimmunoglobulinemia with periodic fever syndrome (HIDS).

Patients with MKD (mevalonic aciduria or hyperimmunoglobulinemia with periodic fever syndrome (HIDS)) may be eligible for a research study conducted at Oregon Health \& Science University (OHSU) in Portland, Oregon USA. The purpose of the study is to find out more about how these diseases affect body chemistry and health. The researchers also want to find out how cholesterol in the diet affect blood cholesterol and how the body handles cholesterol. This is a short-term and long-term dietary study. The long-term goal of this research is to see if controlling dietary cholesterol can decrease any of the symptoms of the diseases.

The study could involve up to 12 one-week admissions to OHSU over the course of 5 years.

Read the detailed description

Participants are admitted to the clinical research center for up to a week per visit. Additional visits at least yearly encouraged. During the week we measure such things as cholesterol absorption, sterol and bile acid synthesis, mevalonate and mevalonate shunt products, isoprenoids, fatty acids, leukotrienes, plasma cholesterol and other sterol levels. Also, the effects of altering dietary cholesterol on plasma 24-S OH-cholesterol, a measure of brain cholesterol turnover, will be evaluated. Studies of body composition/ metabolism/ growth, development, behavior, sleep, feeding, hearing and vision will be carried out to document the phenotype and determine if dietary intervention may be helpful.

The objective of the study is to characterize the metabolic and phenotypic consequences of MKD and study the effects of altering dietary cholesterol in MKD. We hypothesize that some of the phenotypic effects of MKD are due to altered cholesterol metabolism, but that the phenotype is predominantly due to derangements in isoprenoid metabolism.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Determine the effects of dietary cholesterol changes in MKD on cholesterol and related synthetic pathways

    Measured: December 2011

Secondary outcomes (1)
  1. Define genotype, phenotype and response to dietary cholesterol. Determine genotype-therapy correlations.

    Gene Mutations - 7-dehydrocholesterol levels

    Measured: December 2011

Questions about this trial

What is this clinical trial studying?

An observational study of Mevalonic Aciduria and Mevalonate Kinase Deficiency, run by Oregon Health and Science University 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 2 inclusion and 1 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: stopped early, as of the sponsor's last update on 24 May 2019. 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. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study was stopped early (reason given: Not enough participants). Results are not available in the source record.

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?

Determine the effects of dietary cholesterol changes in MKD on cholesterol and related synthetic pathways (time frame: December 2011). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 24 May 2019.
