A Randomized, Open-Label, Phase I, Single-Dose Study of Antisense Oligonucleotide, Vupanorsen, in Chinese Adults with Elevated Triglycerides.

Background: Vupanorsen is a GalNAc-conjugated antisense oligonucleotide targeting angiopoietin-like 3 (ANGPTL3) mRNA shown to reduce atherogenic lipoproteins in individuals with dyslipidemia.

Objectives: The aim of this study was to satisfy Chinese regulatory requirements and support ethnic sensitivity assessment by evaluating pharmacokinetics (PK), pharmacodynamics (PD), and safety of vupanorsen in healthy Chinese adults with elevated triglycerides (TG).

Methods: In this phase I, parallel-cohort, open-label study, 18 Chinese adults with elevated fasting TG (≥ 90 mg/dL) were randomized 1:1 to receive a single subcutaneous dose of vupanorsen 80 mg or 160 mg.

Viral SARS-CoV-2 Rebound Rates in Linked Commercial Pharmacy-Based Testing and Health Care Claims.

Background: Viral SARS-CoV-2 rebound (viral RNA rebound) is challenging to characterize in large cohorts due to the logistics of collecting frequent and regular diagnostic test results. Pharmacy-based testing data provide an opportunity to study the phenomenon in a large population, also enabling subgroup analyses. The current real-world evidence approach complements approaches focused on smaller, prospective study designs.

Subphenotypes of self-reported symptoms and outcomes in long COVID: a prospective cohort study with latent class analysis.

Objective: To characterise subphenotypes of self-reported symptoms and outcomes (SRSOs) in postacute sequelae of COVID-19 (PASC).

Design: Prospective, observational cohort study of subjects with PASC.

Setting: Academic tertiary centre from five clinical referral sources.

Reductions in remnant cholesterol and VLDL cholesterol through inhibition of ANGPTL3 protein synthesis: an analysis from the TRANSLATE-TIMI 70 trial.

Aims: Remnant cholesterol and very low-density lipoprotein cholesterol (VLDL-C) are increasingly recognized risk factors for atherosclerotic disease with few therapeutic options. Angiopoietin-like 3 (ANGPTL3), a key protein in the metabolism of triglyceride-rich lipoproteins, is a promising target.

Methods And Results: TRANSLATE-TIMI 70 was a double-blind, placebo-controlled randomized trial testing seven dose regimens of vupanorsen, an antisense oligonucleotide against ANGPTL3, in adults with non-HDL-C ≥ 100 mg/dL and triglycerides 150-500 mg/dL.

Hepatic fat changes with antisense oligonucleotide therapy targeting ANGPTL3.

Background: Angiopoietin-like protein 3 (ANGPTL3) is a novel therapeutic target for hyperlipidemia. Vupanorsen, an antisense oligonucleotide targeting ANGPTL3, reduced triglycerides up to 57% in a phase 2b trial, but caused dose-dependent increases in hepatic fat fraction (HFF).

Objective: To determine the degree of HFF progression with escalating doses of vupanorsen, differential HFF increases in key patient subgroups, and the correlation between changes in HFF and liver enzymes.
