In plain English

This study looks at whether a medicine called inclisiran is effective and safe for children aged 6 to under 12 with heterozygous familial hypercholesterolaemia (HeFH) — an inherited condition causing high cholesterol. The trial is run by Novartis Pharmaceuticals.

Who can take part

  • Boys or girls aged 6 to under 12 at screening
  • Diagnosed with heterozygous familial hypercholesterolaemia, either by genetic testing or based on signs and symptoms
  • Fasting 'bad' cholesterol (LDL-C) above 130 mg/dL (3.4 mmol/L) at screening
  • Children aged 8 to under 12 should be on the best dose of a statin medicine (unless they cannot tolerate it), with or without other cholesterol-lowering medicines such as ezetimibe; for children under 8, taking cholesterol medicine is decided by the study doctor
  • If already taking cholesterol-lowering medicines, the dose must have been stable for at least 30 days before screening, with no planned changes during the study

Who may not be able to

  • Treatment within the last 90 days with monoclonal antibody medicines targeting PCSK9 (a protein involved in cholesterol control)
  • High cholesterol caused by another condition, such as an underactive thyroid or nephrotic syndrome (a kidney problem)
  • Homozygous familial hypercholesterolaemia (a more severe form of the condition)
  • Body weight under 16 kg at screening or on Day 1
  • Active liver disease, including unexplained high liver enzyme levels (ALT or AST over 3 times the normal limit) or high bilirubin (over 2 times the normal limit, except with Gilbert's syndrome)
  • Girls who are pregnant or breastfeeding
  • Recent or planned use of other experimental medicines or devices

What taking part involves

  • • Taking part involves receiving the study medicine, inclisiran, so researchers can assess how effective and safe it is — further details of how it is given and the study groups are not stated — ask the trial team
  • • Keeping any existing cholesterol medicines at a stable dose, with no planned changes, throughout the study

Time commitment: Not stated — ask the trial team (the data does not say how long the study lasts, how many visits are needed, or what tests are involved).

About This Trial

This is a pivotal phase III study designed to evaluate safety, tolerability, and efficacy of inclisiran in children (aged 6 to \<12 years) with heterozygous familial hypercholesterolemia (HeFH) and elevated low density lipoprotein cholesterol (LDLC).

More detail

This is a two-part (1 year double-blind inclisiran versus placebo / 1 year open-label inclisiran) multicenter study designed to evaluate safety, tolerability, and efficacy of inclisiran in children (aged 6 to \<12 years) with heterozygous familial hypercholesterolemia (HeFH) and elevated low density lipoprotein cholesterol (LDL-C) on stable standard of care background lipid-lowering therapy.
