CORALreef HeFH trial

Efficacy and Safety of Oral PCSK9 Inhibitor Enlicitide in Adults With Heterozygous Familial Hypercholesterolemia: A Randomized Clinical Trial.

The bottom line

In patients with heterozygous familial hypercholesterolemia already on statin therapy, adding oral enlicitide substantially and safely lowered LDL-C and other atherogenic lipid measures compared with placebo.

Primary lipid endpoint metUS status: US-approved

Who took part

Follow-up

Main question
Mean percentage change in LDL-C level at week 24

Main result

The mean percentage change in LDL-C level at week 24 was -58.2% in the enlicitide group vs 2.6% in the placebo group (between-group difference, -59.4% [95% CI, -65.6% to -53.2%]; P < .001).

Effect on LDL cholesterol

-58.2% (enlicitide) vs 2.6% (placebo) at week 24; between-group difference -59.4% (95% CI, -65.6% to -53.2%), P<.001. At week 52: -55.3% vs 8.7%; between-group difference -61.5% (95% CI, -69.4% to -53.7%), P<.001.

Other results

At week 24, mean percentage change in non-HDL-C was -52.3% vs 2.1% (difference -53.0% [95% CI, -58.5% to -47.4%]; P<.001); apolipoprotein B was -48.2% vs 1.8% (difference -49.1% [95% CI, -54.0% to -44.3%]; P<.001); median percentage change in lipoprotein(a) was -24.7% vs -1.6% (difference -27.5% [95% CI, -34.3% to -20.6%]; P<.001).

Safety

The incidence of adverse events, serious adverse events, and study discontinuation due to adverse events was similar between groups.

In the trial's own words

“The mean percentage change in LDL-C level at week 24 was -58.2% in the enlicitide group vs 2.6% in the placebo group (between-group difference, -59.4% [95% CI, -65.6% to -53.2%]; P < .001).”
