Abstract

Elevated apoC-III levels predict increased cardiovascular risk when present on LDL and HDL particles. We developed novel high-throughput chemiluminescent ELISAs that capture apoB, lipoprotein (a) [Lp(a)], and apoA-I in plasma and then detect apoC-III on these individual lipoproteins as apoCIII-apoB, apoCIII-Lp(a), and apoCIII-apoAI complexes, respectively. We assessed the effects on these complexes of placebo or 100-300 mg volanesorsen, a generation 2.0+ antisense drug that targets apoC3 mRNA in patients with hypertriglyceridemia, including familial chylomicronemia syndrome (n = 3), volanesorsen monotherapy (n = 51), and as add-on to fibrate (n = 26), treated for 85 days and followed for 176 days. Compared with placebo, volanesorsen was associated with an 82.3 ± 11.7%, 81.3 ± 15.7%, and 80.8 ± 13.6% reduction in apoCIII-apoB, apoCIII-Lp(a), and apoCIII-apoA-I, respectively (300 mg dose;P< 0.001 for all), at day 92. Strong correlations in all assay measures were noted with total plasma apoC-III, chylomicron-apoC-III, and VLDL-apoC-III. In conclusion, novel high-throughput ELISAs were developed to detect lipoprotein-associated apoC-III, including for the first time on Lp(a). Volanesorsen uniformly lowers apoC-III on apoB-100, Lp(a), and apoA-I lipoproteins, and may be a potent agent to reduce triglycerides and cardiovascular risk mediated by apoC-III.

  • In the COMPASS trial, volanesorsen demonstrated substantial triglyceride reductions (~71%) and improved metabolic parameters in patients with multifactorial chylomicronemia.

    “The COMPASS trial, which evaluated volanesorsen in patients with multifactorial chylomicronemia (with partial LPL activity), similarly demonstrated substantial TG reductions (~ 71%) and improved metabolic parameters, broadening the potential utility of apoC-III inhibition beyond the rare FCS population.”

    From Targeting Triglycerides in Cardiovascular Disease Prevention: Evidence, Mechanisms, and Emerging Therapies (2026) · cites this paper as [46]

    The introduction (p. 2) reports approximately 70% triglyceride reductions with volanesorsen across earlier studies, and the Discussion (p. 7) identifies COMPASS as a volanesorsen study in patients with hypertriglyceridemia. It describes COMPASS as ongoing, however; it does not report a 71% reduction or improved metabolic parameters from that trial, or identify its participants as having multifactorial chylomicronemia with partial LPL activity.

  • Volanesorsen reduces apoC-III by ~80-88% and increases HDL-C by ~42% compared with placebo.

    “In addition to TG lowering, volanesorsen has been shown to reduce apoC-III by ~ 80–88% and increase HDL-C by ~ 42% compared with placebo [45–47].”

    From Targeting Triglycerides in Cardiovascular Disease Prevention: Evidence, Mechanisms, and Emerging Therapies (2026) · cites this paper as [46]

    The Abstract (p. 2) reports approximately 81–82% reductions in lipoprotein-associated apoC-III versus placebo at the 300 mg dose, supporting the apoC-III portion approximately. The Laboratory measurements section (p. 3) says HDL-C was measured, but the passages found do not report a 42% HDL-C increase versus placebo. (LLM, conf=0.88)

    Experimental — accuracy not yet measured
  • Volanesorsen treatment correlated with >80% reductions in apo C-III, favourable changes across multiple lipoprotein species, unchanged LDL-C and improved carbohydrate metabolism.

    “This correlated with >80% reductions in apo C-III, favourable changes across multiple lipoprotein species, unchanged LDL-C and improved carbohydrate metabolism.69–71”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
