Overview

Inclisiran sodium, a small interfering RNA (siRNA) directed to proprotein convertase subtilisin kexin type 9 (PCSK9), is an antilipemic agent.

Inclisiran is a double-stranded small interfering RNA (siRNA), conjugated on the sense strand with triantennary N-acetylgalactosamine to facilitate delivery to hepatocytes with high affinity. In hepatocytes, inclisiran utilizes the RNA interference mechanism and directs catalytic breakdown of mRNA for proprotein convertase subtilisin kexin type 9 (PCSK9), the protein that promotes the degradation of low-density lipoprotein (LDL) receptors. This results in increased LDL-C receptor recycling and expression on the hepatocyte cell surface, which increases LDL-C uptake and lowers its levels in the circulation.

Thus, the mechanism is unique in comparison with the monoclonal antibodies (alirocumab, evolocumab) that target PCSK9.

Reduction in LDL-C was apparent within 14 days following a single, subcutaneous dose of inclisiran 284 mg. Mean LDL-C reductions of 38-51% were observed 30-180 days post-dose, with LDL-C levels reduced by approximately 53% at day 180. Following administration of 2 doses of inclisiran 284 mg (on day 1 and day 90), mean serum PCSK9 levels were reduced by approximately 75% and 69% at day 120 and day 180, respectively.

Following 4 doses of inclisiran (administered on days 1, 90, 270, and 450), levels of LDL-C, total cholesterol, apolipoprotein B, and non-high-density lipoprotein cholesterol were reduced.

Following administration of a single subcutaneous dose, systemic exposure to inclisiran increased in a linear and dose-proportional manner over a dosage range of 25-800 mg. Peak plasma concentrations were achieved in approximately 4 hours after a single dose of inclisiran 284 mg; concentrations were undetectable after 24-48 hours after dosing. Pharmacokinetic findings following multiple subcutaneous administrations were similar to single-dose administration.

Inclisiran is 87% bound to plasma proteins in vitro. Inclisiran has been shown to have high, selective uptake into the liver, the target organ for cholesterol lowering. Inclisiran is metabolized primarily by nucleases to shorter nucleotides of varying length.

The terminal elimination half-life of inclisiran is approximately 9 hours; no accumulation occurs with multiple dosing. Approximately 16% of the drug is cleared through the kidney. The pharmacokinetics of inclisiran are not significantly influenced by patient age, body weight, gender, or race.

USES: Inclisiran is used to help lower "bad" cholesterol (LDL) in the blood. It should be used along with other LDL-lowering medications (such as "statin" drugs) and a proper diet. Inclisiran works by improving how well your body gets rid of LDL cholesterol.

Lowering "bad" cholesterol decreases the risk of heart disease and helps prevent strokes and heart attacks. In addition to eating a proper diet (such as a low-cholesterol/low-fat diet), other lifestyle changes that may help this medication work better include exercising, losing weight if overweight, and stopping smoking. Consult your doctor for more details.
