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).

What Stage of Research Is This?

Phase 3 trials confirm efficacy and safety in large patient groups (often 300–3,000+) and form the evidence base for an FDA approval submission. For Familial Hypercholesterolemia - Heterozygous, Phase 3 studies typically randomize participants between the investigational treatment and either a placebo or current standard of care. A successful Phase 3 result is the threshold most treatments need to clear before regulatory approval.

This trial is currently recruiting participants. The sponsor has registered the study with ClinicalTrials.gov as actively enrolling, which means new applicants who meet the eligibility criteria can be considered for screening. Trial status can change between updates — confirm current recruiting status with the study contact before traveling for a screening visit.

Target enrollment of 51 participants puts this in the typical range for a Phase 2-style efficacy study or a moderate Phase 3 trial in a focused Familial Hypercholesterolemia - Heterozygous subpopulation. At this scale, the study has enough statistical power to detect a clear treatment effect but is not the largest cohort in the field.

Who May Be Eligible (Plain English)

Who May Qualify: - Male or female participants, 6 to \<12 years of age at screening - HeFH diagnosed either by genetic testing or on phenotypic criteria - Fasting LDL-C \>130 mg/dL (3.4 mmol/L) at screening - For participants 8 to \<12 years, on an optimal dose of statin (investigator's discretion) unless statin intolerant, with or without other lipid-lowering therapy (e.g. ezetimibe). For participants \<8 years, the use of background lipid-lowering treatment is based on investigator's discretion. - Participants on lipid-lowering therapies (such as statin and/or e.g. ezetimibe) must be on a stable dose for ≥30 days before screening with no planned medication or dose changes during study participation. Who Should NOT Join This Trial: - Previous treatment (within 90 days of screening) with monoclonal antibodies directed towards PCSK9 - Secondary hypercholesterolemia, e.g. hypothyroidism or nephrotic syndrome - Homozygous familial hypercholesterolemia (HoFH) - Body weight \<16 kg at the screening and/or randomization (Day 1) visit - Active liver disease defined as any known current infectious, neoplastic, or metabolic pathology of the liver or unexplained alanine aminotransferase (ALT), aspartate aminotransferase (AST) elevation \>3x ULN, or total bilirubin elevation \>2x ULN (except patients with Gilbert's syndrome) - Pregnant or nursing females - Recent and/or planned use of other investigational medicinal products or devices Always talk to your doctor about whether this trial is right for you.

How to Talk to Your Doctor About This Trial

Bring the printable summary of this trial — including the NCT ID (NCT06597019), the sponsor (Novartis Pharmaceuticals), and the key eligibility criteria — to your next appointment. Your doctor can review the inclusion and exclusion criteria against your medical history, lab values, and current treatments to assess whether you are likely to qualify. They can also help you weigh whether trial participation makes sense alongside your existing care plan.

Useful questions to walk through together: What does the trial protocol require beyond standard care? How long is the active treatment phase, and how long is follow-up? Are there study visits at sites I can reach? Who pays for the trial-specific procedures, and who pays for standard-of-care portions? See our 25 questions to ask about clinical trials guide for a more complete checklist.
