Plain-language summary
The purpose of this study is to investigate the use of radiolabeled particulate cholesterol administered intravenously in association with albumin, as a method to study reverse cholesterol transport (RCT) in people carrying mutations in genes known to affect high density lipoprotein (HDL) metabolism by analyzing changes in the tracer activity in total plasma, lipoproteins fractions and feces.

Inclusion criteria
. Men and women between the ages of 18 and 75
. Subjects must be:
. Carriers of functional mutations of genes encoding proteins affecting HDL metabolism;
. Healthy control subjects with HDL cholesterol levels within the normal range of the lab where screening tests are run, or at the discretion of the investigator, and matched for gender, race, age (± 5 years) to the patients.
. Negative screening pregnancy test if female of child bearing potential (females of child-bearing potential must be following a medically accepted form of contraception)
. Subjects must be able to comprehend and willing to provide a signed IRB approved Informed Consent Form.
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
What they're measuring
1
determination of 3H cholesterol in plasma and lipoproteins
. Subjects must be willing and able to comply with all study-related procedures.
Exclusion criteria
. Known cardiovascular disease, including coronary disease, cerebrovascular disease, or peripheral vascular disease (control subjects only)
. History of diabetes mellitus or fasting glucose \> 126 mg/dL at the screening visit (control subjects only).
. Any current, unstable endocrine disease as assessed by collection of medical history during screening. Subjects with rare Mendelian disorders with thyroid disease that is well controlled by stable treatment may be considered for enrollment at the discretion of the principal investigator
. History of previous malignancy, other than basal cell or squamous cell carcinoma of the skin, from which the patient has been disease free for less than 5 years as assessed by collection of medical history during screening
. Current diagnosis of anemia as assessed by collection of medical history during screening or hemoglobin less than 10 g/dL as evaluated during safety lab at screening
. History of kidney disease or chronic renal insufficiency, as defined as estimated glomerular filtration rate (eGFR) \< 60 ml/min/1.73m2 in control subjects and patients with other disorders of HDL metabolism and eGFR \< 30 ml/min/1.73m2 in subjects with Lecithin-Cholesterol Acyltransferase (LCAT) deficiency.
. Any active rheumatologic, pulmonary, or dermatologic disease or inflammatory condition as assessed by collection of medical history during screening, and judged by the investigator to be a major condition.
. Sustained uncontrolled hypertension (Systolic \>160 mm Hg and/or Diastolic BP \>100 mmHg) at screening. Blood pressure may be re-tested twice after initial assessment in the supine position at five minute intervals (for a total of 3 blood pressure assessments). The pressure elevation is considered sustained if either the systolic or the diastolic pressure values are outside the stated limits for all three assessments
