ABSTRACT
ApoC-III inhibits lipoprotein lipase and hepatic uptake of triglyceride-rich lipoproteins. It is unknown whether targeting apoC-III affects hepatic steatosis in patients with hypertriglyceridemia. We studied the effect of volanesorsen, a potent antisense oligonucleotide targeting APOC3 mRNA, on hepatic fat fraction (HFF) assessed by MRI in patients with severe hypertriglyceridemia (SHTG, triglycerides ≥500 mg/dL), familial partial lipodystrophy (FPL, triglycerides ≥200 mg/dL) and familial chylomicronemia syndrome (FCS, triglycerides ≥750 mg/dL). The data were evaluated individually in COMPASS (SHTG), APPROACH (FCS), and BROADEN (FPL) trials. The baseline absolute HFF were elevated in all three trials and ranged from 6.3-18.1%. In COMPASS, compared to placebo, volanesorsen significantly reduced the absolute HFF by -3.02% (95% CI, (-5.60, -0.60), p = 0.009) (placebo-adjusted % change from baseline -24.2%, p = 0.034) from baseline to 6 months. In APPROACH a non-significant absolute -1.0% (95% CI, -2.9, 0.0, p = 0.13) reduction in HFF was noted from baseline to 12 months (placebo-adjusted % change from baseline -37.1%, p = 0.20). In BROADEN volanesorsen significantly reduced the absolute HFF by -8.34% (95% CI, -13.01, -3.67, p = 0.001) from baseline to 12 months (placebo-adjusted % change from baseline -52.7%, p = 0.004). In all 3 trials individually, a strong inverse correlation was present between the baseline HFF and the change in HFF in the volanesorsen groups, but not in the placebo groups. In conclusion, apoC-III inhibition with volanesorsen has favorable effects in HFF in patients with different etiologies of hypertriglyceridemia.
