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.

Detailed Description

Homozygous Familial Hypercholesterolemia (HoFH) is a rare genetic metabolic disorder characterized by markedly elevated LDL-cholesterol (LDL-C) levels, resulting in severe atherosclerosis often leading to early onset of cardiovascular disease. The most frequent cause is mutation in the LDL receptor gene (LDLR). LDL-C levels remain frequently above acceptable levels despite treatment with multiple existing lipid lowering drugs and/or LDL apheresis. Thus, the functional replacement of the defective LDLR via AAV-based liver-directed gene therapy may be a viable approach to treat this disease and improve response to current lipid-lowering treatments. The purpose of this protocol is to identify and screen potential candidates for future enrollment in a gene therapy clinical trial. No study drug will be administered in this screening study.

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

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Sampling Method

Non-Probability Sample

Study Population

Patients with clinical diagnosis compatible with homozygous familial hypercholesterolemia (HoFH)

Description

Inclusion Criteria:

  • Males and females ≥ 18 years of age
  • Clinical presentation consistent with homozygous FH
  • Subjects must be able to comprehend and willing to provide a signed IRB approved Informed Consent Form

Exclusion Criteria:

  • Known to carry confirmed mutations in genes affecting LDL receptor functionality other than the LDLR gene
  • History of cirrhosis based on documented histological evaluation or non-invasive imaging
  • Documented diagnosis of any of the following liver diseases: Hepatitis B or C; Biopsy-proven nonalcoholic steatohepatitis; Biopsy-proven alcoholic liver disease; Autoimmune hepatitis; Primary biliary cirrhosis; Primary sclerosing cholangitis; Wilson's disease; Hemochromatosis; alpha1 anti-trypsin deficiency
  • History of immunodeficiency diseases, including a positive HIV test result
  • Previous organ transplantation
  • Serious or unstable medical or psychological conditions that, in the opinion of the investigator, would compromise the subject's safety or successful participation in the study
  • Inability to participate

These dates track the progress of study record and summary results submissions to ClinicalTrials.gov. Study records and reported results are reviewed by the National Library of Medicine (NLM) to make sure they meet specific quality control standards before being posted on the public website.

Study Major Dates

Study Start

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.
March 1, 2016

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.

Study Completion (Actual)

Study Completion

The date on which the last participant in a clinical study was examined or received an intervention/treatment to collect final data for the primary outcome measures, secondary outcome measures, and adverse events (that is, the last participant's last visit). The "anticipated" study completion date is the date that the researchers think will be the study completion date.
