What the trials found For clinicians

Heterozygous Familial Hypercholesterolemia: what the trials found

Several pharmacological interventions have demonstrated significant reductions in LDL-C for patients with Heterozygous Familial Hypercholesterolemia. Inclisiran demonstrated substantial and sustained reductions in LDL-C, with a -41.15% change at Day 510 1, a -50.02% reduction from the initial feeder study baseline 5, and a -27.14% reduction at Day 330 6. Additionally, Inclisiran was associated with significant decreases in PCSK9 levels 11.

Other established therapies include Bococizumab, which achieved a -54.2% reduction in LDL-C at Week 12 2, and Evolocumab, which showed a -44.53% reduction in LDL-C at Week 24 3. Lipid-lowering medications (LMT) including atorvastatin, simvastatin, or rosuvastatin resulted in a -48.7% reduction in LDL-C at Week 24 8. Mipomersen sodium also demonstrated a -28.02% reduction in LDL-C and a -26.31% reduction in Apolipoprotein B 9.

Clinical data also indicate that placebo groups showed a -53.7% reduction in calculated LDL-C (pre-apheresis) at Week 6, which was associated with a significant change in the standardized rate of apheresis treatments 4. Additionally, a fixed-dose combination of EZ and Atorva was evaluated, with 82.9% of participants experiencing at least one adverse event 7.

Recent results — preliminary, needs further review

  • MGL-3196 (resmetirom) showed a -10.6% mean reduction in LDL-C, a -12.0% reduction in Non-HDL-C, and a -18.3% reduction in triglycerides at Week 12 10.

For the clinician treating this condition

  • Inclisiran provides significant and sustained LDL-C reduction (approx. 27-50%) and associated PCSK9 reduction [1, 5, 6, 11].
  • Bococizumab and Evolocumab are established options for significant LDL-C reduction [2, 3].
  • LMT and mipomersen are established interventions for reducing LDL-C and Apolipoprotein B [8, 9].
