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

  • (BMI) ≤ 35 kg/m2,
  • Genetic confirmation of two mutant alleles at the LDLR, APOB, PCSK9, or LDLRAP1 gene locus OR an untreated LDL-C > 500 mg/dL (13 mmol/L) or treated LDL-C ≥ 300 mg/dL (2.59 mmol/L) together with either cutaneous or tendon xanthoma before age 10 years OR familial medical history of genetically confirmed heterozygous FH in both parents OR untreated elevated LDL-C and TC > 250 mg/dL consistent with the disease,
  • Patients must be on stable LDL-C lowering agents or on regular apheresis

Exclusion criteria

Exclusion Criteria:

  • Myocardial infarction, percutaneous transluminal coronary intervention, or coronary artery bypass graft surgery within 12 weeks prior to Screening, or cerebrovascular accident within 24 weeks prior to Screening.
  • Diabetes mellitus if newly diagnosed or if ≥ 9.0%
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.

BMI (body mass index)

Weight in kilograms divided by height in metres squared. Example: 70 kg and 1.75 m gives 70 ÷ (1.75 × 1.75) ≈ 22.9.

What counts as overweight or obesity differs between countries (some use lower cut-offs), so go by the range the study states.

HbA1c

A blood test of average blood sugar over the past two to three months, given as a percentage or in mmol/mol. 6.5% (48 mmol/mol) or more is the usual threshold for diabetes, normally confirmed by a second test.

What researchers measure

Primary outcomes

  1. Reduction of low density lipoprotein cholesterol (LDL-C).

    Percent change in LDL-C from Baseline to week 14.

    Time frame: 14 weeks

Secondary outcomes

  1. Effect of ISIS 703802 on plasma angiopoietin like 3 (ANGPTL3).

    Absolute and percentage change in ANGPTL3 protein from Baseline to Week 14 will be summarized.

    Time frame: 7 and 14 Weeks

  2. Effect of ISIS 703802 on lipid parameters.

    Absolute and percentage change from Baseline to Week 14 will be summarized.

    Time frame: 7 and 14 Weeks

  3. Evaluate plasma trough levels of ISIS 703802.

    Plasma trough levels of ISIS 703802 during treatment period and those during post-treatment follow up period will be descriptively summarized.

    Time frame: 14 Weeks

  4. The safety of ISIS 703802 by the incidence of treatment-emergent adverse events

    The safety of ISIS 703802 will be assessed by determining adverse effects.

    Time frame: 14 Weeks

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 Dec 3, 2018, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
