Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  • Male and non-pregnant female patients or female patients of childbearing age on age 18-80years.
  • Total HDL level 38mg/dL or lower in men and HDL 45 mg/dL or lower in women and a low HDL-P defined as less than 7000 by Spectracell LPP Plus.
  • CHL HDL Fx score equal to or greater than 0.9.
  • Patients will remain on their present diet, exercise program, medications (except for those who alter serum lipids) sleeping habits, alcohol intake, caffeine intake, smoking amount and emotional status as best as possible related to stress and anxiety and maintain body weight at baseline visit as best as possible to avoid confounding variables.
  • No other lipid lowering supplement can be taken during the study.
  • All lipid lowering supplements must have been discontinued at least 30 days prior t o study entry.

Exclusion criteria

Exclusion Criteria:

  • Pregnant females
  • Females of childbearing age not on an accepted control method
  • Previous myocardial infarction within 5 years
  • Unstable angina
  • Previous stroke or within 5 years
  • Uncompensated congestive heart failure
  • Previous PCTA or stent within 5 years
  • Previous CABG within 5 years
  • Patients on statins, fibrates, or other lipid lowering medications or any supplement known to affect serum lipids.
  • Known or previous cancer within 5 years
  • Type 1 diabetes mellitus
  • Kidney disease as defined by serum creatinine over 2.5 mg/dL
Terms in these criteria, in plain language(2)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Contraception

Ways of preventing pregnancy. “Highly effective” methods fail less than 1% of the time a year when used correctly — for example an IUD or an implant.

Criteria usually say which methods count and how long to keep using them after the last dose, sometimes for male participants too. Some studies accept a partner’s vasectomy if it was confirmed successful and that person is the participant’s only sexual partner.

TIA (transient ischaemic attack)

A “mini-stroke”: temporary stroke-like symptoms caused by reduced blood flow to part of the brain, spinal cord or eye, without signs of a new stroke on a scan.

Stroke symptoms need emergency care at once, even if they go away.

Study arms

  • Active comparator
    Active HDL supplement

    25 subjects (ages 18-85 years old) will receive an active HDL supplement (CardioLux™HDL). They will take 2 capsules twice a day with food for 12 weeks. Total daily dosing is four (4) capsules.

    Dietary Supplement: CardioLux™HDL

  • Placebo comparator
    Placebo

    25 randomly selected subjects (ages 18-85 years old) will receive a matching Placebo. They will take 2 capsules twice each day with food for 12 weeks. Total daily dosing is four (4) capsules.

    Dietary Supplement: Placebo

Interventions

  • Dietary supplementCardioLux™HDL

    Enrollment will occur according to the inclusion/ exclusion criteria and after the review and signing of the Informed Consent form. Clinical testing will be performed at baseline and each visit (2, 3). Measurement of height, weight with body composition analysis, body mass index, waist circumference, and vital signs (blood pressure, heart rate) will be measured. Review of medical history and current medications by clinician; and collection of fasting blood for testing of the complete blood count (CBC), comprehensive metabolic profile (CMP), as well as a urine pregnancy test in females of child-bearing potential. Visits: Baseline (Visit 1), Week 6 (Visit 2) and Week 12 (Visit 3/End of Study)

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Mar 15, 2024, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
