Effect of ANGPTL3 Inhibition With Solbinsiran in Preclinical and Early Human Studies

J Am Coll CardiolPublished

  • Preclinical and phase 1 randomised placebo-controlled study
  • single-ascending-dose
  • repeat-dose
  • Evaluated over 169 days

Authors' conclusion

Solbinsiran inhibits hepatic ANGPTL3 translation and results in significant reductions in all atherogenic lipoproteins in mixed dyslipidemia.

Study context

Population
Participants with mixed dyslipidemia; mouse and nonhuman primate models
Comparison
Solbinsiran vs placebo

Primary result

As reported in the abstract

Mean % reductions from baseline, single dose (humans)
ANGPTL3 reduction up to
86% ± 4%
Triglycerides reduction up to
73% ± 7%
LDL-C reduction up to
30% ± 16%
Non-HDL-C reduction up to
41% ± 12%
Apolipoprotein B reduction up to
30% ± 11%

Further findings

Repeat-dose study, reductions

ANGPTL3
89% ± 6%
Triglycerides up to
70% ± 13%
LDL-C up to
42% ± 14%
Non-HDL-C up to
46% ± 14%
Apolipoprotein B up to
36% ± 13%
  • P < 0.0001 for all

Preclinical ANGPTL3 expression

Mice: hepatocyte ANGPTL3 messenger RNA (mRNA) reduction vs vehicle
65%
Monkeys: hepatic ANGPTL3 mRNA reduction up to (mean ± SEM)
73% ± 2% (P < 0.0001)
Monkeys: serum ANGPTL3 protein reduction up to (mean ± SEM)
69% ± 4% (P < 0.001)

NMR lipoprotein analysis

Reductions in total number of triglyceride-rich lipoprotein and low-density lipoprotein (LDL) particles with solbinsiran

Safety

Adverse events

Mostly mild; similar incidence with solbinsiran and placebo
