Inclisiran (Leqvio) — PCSK9-targeting siRNA
A small interfering RNA (siRNA) prescription drug (Leqvio) that silences PCSK9 in the liver, cutting LDL cholesterol ~50%. Distinctive for being dosed by subcutaneous injection only twice a year after the first doses — a major adherence advantage. LDL lowering is well established (ORION-9/-10/-11); cardiovascular-outcome benefit is NOT yet proven (ORION-4/VICTORION trials ongoing). Prescription drug, not a supplement.
Prescription medication — not a dietary supplement
Inclisiran (Leqvio) is a prescription (or investigational) drug, not a supplement. It is included here for reference because people research and discuss it (often used off-label) — not as a recommendation. Take it only under a qualified clinician's supervision and only as prescribed; do not source it from grey-market vendors, where identity, purity, and dosing are unverified. The evidence below reflects its clinical trials.
What the evidence says
Most Inclisiran (Leqvio) studies are mechanism or observational rather than RCTs that measure a clinical effect — keep findings provisional.
Most evidence is from high-quality meta-analyses and randomised trials published 2017–2026 with a typical study size of 3,660 participants.

Confidence
High confidenceBy outcome
Inclisiran produces strong, durable ~50% LDL-cholesterol reductions across a well-conducted phase 3 program (ORION-9/-10/-11) with a twice-yearly dosing advantage, but cardiovascular-outcome benefit — actual reductions in heart attacks, strokes, and CV death — is not yet proven (ORION-4/VICTORION ongoing), so the overall evidence stays Moderate.

Inclisiran is a GalNAc-conjugated small interfering RNA (siRNA) that lowers LDL cholesterol by silencing PCSK9 messenger RNA inside hepatocytes.
The GalNAc sugar targets the molecule to liver cells, where the RNA-interference machinery degrades PCSK9 mRNA — so the liver makes less PCSK9, more LDL receptors stay on the cell surface, and more LDL is cleared from the blood.
It is a fundamentally different approach from statins (which block cholesterol synthesis) and from the PCSK9 monoclonal antibodies evolocumab and alirocumab (which mop up the PCSK9 protein after it is made); inclisiran shuts off production upstream.
The headline distinction is dosing: after an initial dose and one at day 90, inclisiran is given as a subcutaneous injection only twice a year (every 6 months), versus daily statins or fortnightly/monthly antibody injections — a potentially large real-world adherence advantage.
The pivotal phase 3 program (ORION-9 in heterozygous familial hypercholesterolemia, ORION-10 and ORION-11 in atherosclerotic cardiovascular disease / high risk) showed sustained placebo-corrected LDL-C reductions of roughly 48–52% maintained across the dosing interval, and the 4-year ORION-3 open-label extension showed the effect is durable with repeated dosing.
The honest limitation: those are LDL-lowering (surrogate) outcomes. Whether inclisiran actually reduces heart attacks, strokes, and cardiovascular death — the way statins and the PCSK9 antibodies have been shown to — is still unproven, with the cardiovascular-outcomes trials (ORION-4 and the VICTORION program) ongoing.
It is generally well tolerated; the most characteristic adverse effect is injection-site reactions (transient pain, redness, or a hardened area).
It is an expensive prescription drug administered by a clinician, not a supplement, and the score reflects strong, durable LDL-lowering evidence set against pending cardiovascular-outcome data and cost.
A small interfering RNA that engages the RNA-interference machinery to degrade PCSK9 messenger RNA in liver cells, so less PCSK9 protein is made.
A triantennary GalNAc sugar conjugate binds the asialoglycoprotein receptor, delivering the siRNA selectively into hepatocytes — enabling low, infrequent subcutaneous dosing.
Less PCSK9 means more LDL receptors recycle to the cell surface, clearing more LDL cholesterol from the blood — lowering LDL-C by roughly half.

Data are limited; avoid unless a clinician judges benefit to outweigh unknown risk.
Limited data in severe impairment; use under specialist supervision.
Be aware that inclisiran's outcome benefit is unproven; statins and PCSK9 antibodies have demonstrated event reduction.
Commonly and intentionally co-administered (additive LDL lowering); not a harmful interaction but combined lipid lowering should be clinician-monitored.
Redundant mechanism (both lower PCSK9 activity); combining is not standard and offers no established added benefit.
Tip: Usually transient and mild; rotate injection sites (abdomen, arm, thigh).
Tip: Generally self-limited; report persistent symptoms to your clinician.
Tip: Seek care for rash, swelling, or breathing difficulty after injection.
Inclisiran (Leqvio) has an evidence score of 4.1/10 — emerging evidence based on 36 indexed studies, including 2 meta-analyses. A small interfering RNA (siRNA) prescription drug (Leqvio) that silences PCSK9 in the liver, cutting LDL cholesterol ~50%. Distinctive for being dosed by subcutaneous injection only twice a year after the first doses — a major adherence advantage. LDL lowering is well established (ORION-9/-10/-11); cardiovascular-outcome benefit is NOT yet proven (ORION-4/VICTORION trials ongoing). Prescription drug, not a supplement. Representative study: PMID 33663735.
The commonly studied dose of Inclisiran (Leqvio) is 284 mg (300 mg inclisiran sodium) by subcutaneous injection administered by a healthcare professional on day 1, again at day 90 (month 3), then every 6 months thereafter. A prescription drug; this is the approved regimen, not a self-directed supplement protocol.. Individual needs vary — start at the lower end of the range and adjust based on how you respond.
Timing is flexible for Inclisiran (Leqvio) — consistent daily use matters more than the time of day. A twice-yearly clinician-administered subcutaneous injection; timing relative to meals or time of day is not relevant.
Inclisiran (Leqvio) is generally safe at recommended doses, with a few precautions worth noting. The most commonly reported side effects are injection-site reaction (pain, redness, induration), arthralgia / limb pain, hypersensitivity reaction. Use caution if any of these apply to you: Known hypersensitivity to inclisiran or excipients; Not a substitute for a clinician's evaluation — prescription drug only.
Pioglitazone (Actos)
Mostly mechanism / observationalAn oral thiazolidinedione (Actos) diabetes drug that improves insulin sensitivity via PPAR-gamma. It drew geroscience interest after reducing recurrent stroke/MI in insulin-resistant non-diabetics (IRIS) and improving NASH liver histology — but weight gain, fluid retention / heart-failure risk, fracture risk, and a debated bladder-cancer signal keep enthusiasm in check. Prescription drug, not a supplement.
