| CARLSBAD, Calif., Nov. 24, 2021 /PRNewswire/ -- Ionis Pharmaceuticals, Inc., (NASDAQ: IONS) today announced that Pfizer has provided an update on the Phase 2b study of vupanorsen, formerly IONIS-ANGPTL3-LRx. Vupanorsen is an investigational antisense therapy being developed for indications in cardiovascular (CV) risk reduction and severe hypertriglyceridemia (SHTG). In the dose-ranging study in subjects with elevated non-HDL-C and triglycerides (TG), the study met its primary endpoint, achieving a statistically significant reduction in non-HDL-C at all doses tested at 24 weeks, compared to placebo. In addition, subjects treated with vupanorsen achieved statistically significant reductions in TG and ANGPTL3 at all dose levels at 24 weeks, compared to placebo.
“We were pleased to see statistically significant reductions in the primary endpoint, non-HDL-cholesterol, and in the secondary endpoint of triglycerides at all doses tested. The topline results of the Phase 2b study also showed that vupanorsen dose-dependently lowered its target, angiopoietin-like 3. Pfizer is continuing to review the findings to determine next steps regarding future development. We look forward to the full data set being presented at a medical meeting next year,” said Sotirios “Sam” Tsimikas, M.D., vice president of global cardiovascular development and cardiovascular franchise lead at Ionis. The most common adverse events were injection site reactions, which occurred most often in the highest vupanorsen dose group. The most common laboratory abnormalities were increases in liver enzymes, alanine aminotransferase (ALT) and aspartate aminotransferase (AST) and were seen primarily at the higher doses. There were no Hy’s Law cases in vupanorsen-treated subjects, and no meaningful changes in bilirubin. Certain doses of vupanorsen were associated with increases from baseline in hepatic fat fraction, measured by magnetic resonance imaging proton density fat fraction at Week 24, compared to placebo. No subject had a confirmed platelet count abnormality or a confirmed reduction in the estimated glomerular filtration rate. There were no serious adverse events (SAEs) related to treatment. The incidence of SAEs was similar between active and placebo groups. The global multicenter, double-blind, placebo-controlled, dose-ranging Phase 2b study TaRgeting ANGPTL3 with an aNtiSense oLigonucleotide in AdulTs with dyslipidEmia (TRANSLATE-TIMI 70) enrolled 286 participants (≥ 40 years old) with dyslipidemia, defined in this study as participants with elevated non-HDL-C (≥ 100 mg/dL) and TG (150-500 mg/dL), who are receiving a stable dose of a statin. Participants received either 80 mg, 120 mg or 160 mg every 4 weeks, or 60 mg, 80 mg, 120 mg or 160 mg every two weeks via subcutaneous injection. The study was designed to assess the efficacy, safety, tolerability and pharmacokinetics of vupanorsen, and the primary endpoint was percent change from baseline in non-HDL-C at week 24. About vupanorsen Vupanorsen is an investigational antisense therapy discovered by Ionis and being developed by Pfizer for potential indications in CV risk reduction and SHTG. Vupanorsen is designed to reduce the production of ANGPTL3 protein, a key regulator of triglyceride and cholesterol metabolism, in the liver. This antisense therapy was developed using Ionis’ advanced LIgand Conjugated Antisense (LICA) technology. The potential therapeutic benefits of ANGPTL3 reduction are supported by the discovery that people with a genetic deficiency in ANGPTL3 have reduced levels of LDL-C and TG, and a decreased risk of diabetes and CV disease.i In a Phase 1 study, subjects treated with vupanorsen achieved robust, dose-dependent reductions in ANGPTL3, TG, LDL-C, non-HDL-C and total cholesterol with a favorable safety and tolerability profile.ii In a Phase 2a study, vupanorsen met the primary endpoint of significant reductions in TG levels and multiple secondary endpoints compared to placebo, with a favorable safety and tolerability profile.iii In November 2019, Pfizer licensed vupanorsen from Ionis in a worldwide exclusive agreement.
