Built from the registry fields of EU CTIS (euclinicaltrials.eu). It describes the study design.

Who cannot take part

Copied verbatim from EU CTIS (euclinicaltrials.eu) and grouped by topic. Only the trial team decides who can take part.

Prior treatment

  • Participant hospitalized for an unplanned atherosclerotic cardiovascular event the past 6 months prior to study.
  • Participant currently using other drug(s) referred to as contraindicated during atorvastatin treatment, or not compatible with atorvastatin 80 mg, according to the Summary of Product Characteristics.

Other illness

  • Participant with short life expectancy (<24 months) due to other medical conditions.
  • Participant with history of rhabdomyolysis.
  • Participant with history of myopathy (creatine kinase ≥10 times upper limit of the normal range)
  • Participant with history of liver affection (alanine aminotransferase and/or aspartate aminotransferase ≥3 times upper limit of the normal range) associated with statin treatment.
  • Participant with history of severe renal insufficiency last 12 months (estimated glomerular filtration rate < 30 mL/min/1.73m2).
  • Participant with any condition (e.g. psychiatric illness, dementia, substance abuse), that in the principal investigator’s opinion could put the subject at significant risk, confound the study results or interfere significantly with the subject participation in the study.
  • Participant having any contraindication(s) for atorvastatin listed in the Summary of Product Characteristics (including known hypersensitivity to the ingredients, alanine aminotransferase ≥3 times upper limit of the normal range at baseline, pregnancy and breastfeeding).

Other

  • Participant with elevated CK ≥5 times upper limit of the normal range at baseline.
  • Participation in another interventional clinical study.

Who the study is looking for

  • Participant must be ≥18 years of age at the time of signing the informed consent.
  • Participant having genetically verified diagnosis of heterozygous familial hypercholesterolemia or clinical diagnosis of familial hypercholesterolemia with Dutch Lipid Clinic Network Score ≥9.
  • Participant with a history of self-perceived statin-associated muscle symptoms (i.e. muscle symptoms subjectively associated with statin treatment) on at least two different types of statins.
  • Participant having discontinued statin treatment due to associated muscle symptoms (must have been off statin treatment for at least 2 weeks prior to first assessment for study inclusion).
  • If woman of childbearing potential (defined as all premenopausal female that are not permanently sterile); participant must take a pregnancy test with negative result and express willingness to highly effective contraceptive use or adequate sexual abstinence during the study intervention (until the end of intervention).
  • Participant expected to be compliant with the requirements and restrictions listed in the informed consent form and in the protocol.
