Solbinsiran

Solbinsiran has not been approved by the FDA or any regulator; it remains investigational. Eli Lilly evaluated it in the Phase 2 PROLONG-ANG3 study in adults with mixed dyslipidemia on statins (double-blind, randomized, placebo-controlled; 205 participants; subcutaneous dosing on day 0 and day 90 with follow-up to at least day 270), where the 400 mg dose met the primary apoB-lowering endpoint. Lilly has said the efficacy and safety data set the foundation for a Phase 3 cardiovascular outcomes trial, and a Phase 2 study in hypertriglyceridemia has also been initiated. Solbinsiran is developed by Eli Lilly and Company (development code LY3561774).

An approved, once-monthly, self-administered subcutaneous GalNAc-conjugated antisense oligonucleotide (ASO) from Ionis and AstraZeneca that treats transthyretin-mediated (ATTR) amyloidosis by lowering the liver's production of transthyretin (TTR). Transthyretin is a liver-made transport protein that can misfold and deposit as amyloid in nerves and the heart; eplontersen is a short synthetic strand of chemically modified DNA/RNA that binds TTR messenger RNA and directs its enzymatic (RNase H1) degradation before the protein is made, cutting circulating TTR by roughly 80%. A triantennary N-acetylgalactosamine (GalNAc) tag delivers it to liver cells, allowing a low-dose 45 mg injection just once a month via autoinjector or pre-filled syringe. Marketed as Wainua (US) and Wainzua (EU), it was FDA-approved in December 2023 for the polyneuropathy of hereditary ATTR amyloidosis (ATTRv-PN) on the strength of the NEURO-TTRansform trial, and is now approved in more than 20 countries. Eplontersen is the antisense (ASO) counterpart to the siRNA drug vutrisiran (Amvuttra): both silence TTR, and both were tested in ATTR cardiomyopathy - but where vutrisiran's HELIOS-B trial succeeded on top of a stabilizer background, eplontersen's much larger CARDIO-TTRansform cardiomyopathy trial missed its primary endpoint in July 2026, with a benefit seen only in the prespecified monotherapy subgroup. It is a GalNAc-ASO sibling of Ionis's olezarsen and pelacarsen and the second-generation successor to the earlier, non-GalNAc TTR antisense drug inotersen (Tegsedi).

An approved, twice-yearly subcutaneous GalNAc-conjugated small interfering RNA (siRNA) from Novartis (originally discovered by Alnylam) that lowers LDL cholesterol by silencing PCSK9 (proprotein convertase subtilisin/kexin type 9), the liver protein that destroys LDL receptors. By switching off PCSK9 production inside hepatocytes, inclisiran leaves more LDL receptors on the liver surface to pull LDL cholesterol out of the blood - achieving roughly a 50% LDL reduction with an injection given only twice a year after a loading dose. Marketed as Leqvio, it was the first siRNA medicine approved for a chronic cardiovascular condition: the EU cleared it in December 2020 and the FDA in December 2021, and in July 2025 the FDA expanded the U.S. label to first-line monotherapy, dropping the requirement that it be added on top of a statin. Its Phase 3 ORION-9, ORION-10 and ORION-11 trials established the LDL benefit; a large cardiovascular outcomes program (VICTORION-2-PREVENT and others) is still running to test whether that LDL lowering prevents heart attacks and strokes. Inclisiran is the approved, real-world proof-of-concept for the GalNAc-siRNA cardiometabolic platform that newer investigational agents like zodasiran, solbinsiran, olpasiran and plozasiran build on.

An investigational, long-duration injectable small interfering RNA (siRNA) from Eli Lilly that lowers lipoprotein(a) [Lp(a)] by nearly 94% by silencing the LPA gene in the liver. A single dose keeps Lp(a) suppressed for a year or more, and its Phase 3 ACCLAIM-Lp(a) trial (~12,500 patients) is the first Lp(a) outcomes trial to include people who have not yet had a cardiovascular event.

The first oral, small-molecule inhibitor of lipoprotein(a) [Lp(a)] formation, from Eli Lilly. Instead of silencing a gene, muvalaplin is a once-daily pill that physically blocks apolipoprotein(a) from binding apolipoprotein B — the first step in building an Lp(a) particle. In its Phase 2 KRAKEN trial (published in JAMA, 2024) it cut Lp(a) by up to ~86% (placebo-adjusted) and, as of 2026, is the only Lp(a)-lowering drug that is both oral and already enrolling a large Phase 3 cardiovascular outcomes trial (MOVE-Lp(a)).

An investigational once-daily oral, highly selective CETP (cholesteryl ester transfer protein) inhibitor from NewAmsterdam Pharma (European partner Menarini) that lowers LDL cholesterol and lipoprotein(a) [Lp(a)] in a single pill. Unlike the failed first-generation CETP inhibitors, obicetrapib is valued for LDL and Lp(a) lowering rather than HDL raising. In Phase 3 it cut LDL-C by about a third as monotherapy (BROADWAY) and by roughly half combined with ezetimibe (TANDEM), and reduced Lp(a) by ~33% - published in NEJM and The Lancet (2025). It received a positive EMA CHMP opinion in July 2026 (as Ubeslo and Evlarco), with the PREVAIL cardiovascular outcomes trial due to report in 2026.

An FDA-approved subcutaneous antisense oligonucleotide (ASO) from Ionis Pharmaceuticals, branded Tryngolza, that lowers triglycerides by silencing the messenger RNA for apolipoprotein C-III (apoC-III). Self-injected once a month, it was the first-ever therapy approved for familial chylomicronemia syndrome (FCS) on December 19, 2024, and on June 24, 2026 it became the first and only treatment approved to reduce both triglycerides and the risk of acute pancreatitis in the far larger severe hypertriglyceridemia (sHTG) population.

An investigational, once-every-12-weeks injectable small interfering RNA (siRNA) from Amgen that lowers lipoprotein(a) [Lp(a)] by up to ~97% by silencing the LPA gene in the liver. Its Phase 3 OCEAN(a)-Outcomes cardiovascular outcomes trial (~7,000 patients) is one of the pivotal readouts — due December 2026 — that will help decide whether lowering Lp(a) prevents heart attacks and strokes.

A first-in-class, once-monthly injectable antisense oligonucleotide (ASO) from Ionis and Novartis that lowers lipoprotein(a) [Lp(a)] by shutting down apolipoprotein(a) production in the liver. Its pivotal Lp(a)HORIZON trial (8,323 patients) is the first-ever cardiovascular outcomes trial for any Lp(a)-lowering drug, with a landmark topline readout due in 2026.

An approved subcutaneous RNA interference (RNAi) therapy from Arrowhead Pharmaceuticals, branded Redemplo, that silences the gene for apolipoprotein C-III (apoC-III) to lower triglycerides. Given once every three months, it cut triglycerides by roughly 80% in familial chylomicronemia syndrome (FCS) and sharply reduced acute pancreatitis events. The FDA approved it on November 18, 2025 for FCS, and Phase 3 SHASTA-3 and SHASTA-4 (reported July 2026) extended those results to the far larger severe hypertriglyceridemia population.

An approved, quarterly (once-every-three-months) subcutaneous GalNAc-conjugated small interfering RNA (siRNA) from Alnylam that treats transthyretin-mediated (ATTR) amyloidosis by silencing the TTR gene in the liver. Transthyretin is a liver-made transport protein that can misfold and pile up as amyloid deposits in nerves and, critically, the heart; vutrisiran uses RNA interference (RNAi) to degrade both mutant and wild-type TTR messenger RNA before the protein is made, lowering circulating TTR by roughly 80% and starving the amyloid of its raw material. Marketed as Amvuttra, it was first FDA-approved in June 2022 for the polyneuropathy of hereditary ATTR amyloidosis (HELIOS-A), and in March 2025 the FDA expanded the label to ATTR cardiomyopathy (ATTR-CM) of wild-type or hereditary disease - making vutrisiran the first RNAi therapeutic shown to reduce cardiovascular death and cardiovascular events, on the strength of the HELIOS-B outcomes trial. It shares the exact GalNAc-siRNA delivery platform that underlies the cardiometabolic RNAi medicine inclisiran and the investigational agents olpasiran, lepodisiran, zerlasiran, zilebesiran, zodasiran, solbinsiran and plozasiran, and it is the direct successor to Alnylam's earlier intravenous TTR siRNA patisiran (Onpattro).

An investigational, long-acting injectable small interfering RNA (siRNA) from Silence Therapeutics that lowers lipoprotein(a) [Lp(a)] by more than 80% by silencing the LPA gene in the liver. Dosed only every 16–24 weeks, it produced durable ~90% reductions in its Phase 2 ALPACAR-360 trial (published in JAMA, 2024); as of 2026 the company is seeking a partner before starting its Phase 3 cardiovascular outcomes study.

An investigational subcutaneous GalNAc-conjugated small interfering RNA (siRNA) from Alnylam Pharmaceuticals and Roche/Genentech that lowers blood pressure by silencing angiotensinogen (AGT), the single upstream precursor of the renin-angiotensin-aldosterone system (RAAS). Designed for dosing as infrequently as once or twice a year, it is the first RNА interference (RNAi) therapeutic developed for hypertension. In Phase 2 KARDIA-1 and KARDIA-2 trials it produced durable, clinically meaningful reductions in systolic blood pressure sustained for up to 6 months from a single dose, and in 2025 it advanced into the large Phase 3 ZENITH cardiovascular outcomes trial.

An investigational subcutaneous GalNAc-conjugated small interfering RNA (siRNA) from Arrowhead Pharmaceuticals that lowers atherogenic lipids by silencing ANGPTL3 (angiopoietin-like protein 3), a liver-made regulator of fat metabolism. By switching off ANGPTL3 production, zodasiran deeply reduces triglycerides, remnant cholesterol and LDL cholesterol through a pathway that does not depend on the LDL receptor - making it especially relevant for people, such as those with homozygous familial hypercholesterolemia (HoFH), whose LDL receptors barely work. In the Phase 2b ARCHES-2 trial (NEJM 2024) it produced durable, dose-dependent reductions in triglycerides, remnant cholesterol and ANGPTL3, and in the Phase 2 GATEWAY study it lowered LDL cholesterol by about 40% in HoFH. It is now in the Phase 3 YOSEMITE trial in HoFH, which completed enrollment in July 2026.
