Adverse Reactions in Adults with Hypercholesterolemia The data in Table 1 are derived from 3 placebo-controlled trials that included 1,833 adults with hypercholesterolemia treated with LEQVIO, including 1,682 exposed for 18 months (median treatment duration of 77 weeks) [see Clinical Studies (14)] . The mean age of the population was 64 years, 32% of the population were female, 92% were White, 6% were Black or African American, 1% were Asian, and < 1% were other races; 6% identified as Hispanic or Latino ethnicity. At baseline, 12% of patients had a diagnosis of HeFH and 85% had clinical atherosclerotic cardiovascular disease (ASCVD). Adverse reactions reported in at least 3% of LEQVIO-treated patients, and more frequently than in placebo-treated patients, are shown in Table 1. Table 1: Adverse Reactions Occurring in Greater Than or Equal to 3% of LEQVIO-treated Adults with Hypercholesterolemia and More Frequently than with Placebo (Trials 1, 2, and 3) Adverse Reactions Placebo (N = 1,822) % LEQVIO (N = 1,833) % †includes related terms such as: injection site pain, erythema and rash Injection site reaction† 2 8 Arthralgia 4 5 Bronchitis 3 4 Adverse reactions led to discontinuation of treatment in 2.5% of patients treated with LEQVIO and 1.9% of patients treated with placebo. The most common adverse reactions leading to treatment discontinuation in patients treated with LEQVIO were injection site reactions (0.2% versus 0% for LEQVIO and placebo, respectively). Adverse Reactions in Pediatric Patients with HeFH In a 24-month, two-part trial of 141 pediatric patients aged 12 years and older with HeFH (Trial 4), consisting of a 12-month randomized, double-blind, placebo-controlled part (Part 1/Year 1), followed by a 12-month open-label part (Part 2/Year 2), 93 patients received 284 mg of LEQVIO subcutaneously during Part 1 and 139 patients were treated with LEQVIO during Part 2 [see Clinical Studies (14)] . During Part 2, 91 patients continued LEQVIO treatment for a second year and 48 patients switched from placebo to LEQVIO for 1 year of treatment. The safety profile reported in pediatric patients with HeFH was consistent with the description above for adult patients with hypercholesterolemia, with the exception of headache. In pediatric patients with HeFH, the incidence of headache was 6% among patients who received placebo versus 13% of LEQVIO-treated patients during the double-blind study period. Adverse Reactions in Pediatric Patients with HoFH In a 24-month, two-part trial of 13 pediatric patients aged 12 years and older with HoFH (Trial 5), consisting of a 12-month randomized, double-blind, placebo-controlled part (Part 1/Year 1), followed by a 12-month open-label part (Part 2/Year 2), 9 patients received 284 mg of LEQVIO administered subcutaneously during Part 1 and 13 patients were treated with LEQVIO during Part 2 [see Clinical Studies (14)] . During Part 2, 9 patients continued LEQVIO treatment for a second year and 4 patients switched from placebo to LEQVIO for 1 year of treatment. The safety profile reported in pediatric patients was consistent with adult patients with hypercholesterolemia. 6.2 Postmarketing Experience The following adverse reactions have been identified during post-approval use of LEQVIO. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure. Hypersensitivity: anaphylaxis, angioedema, rash, pruritus, and urticaria.

12.3 Pharmacokinetics Absorption Following a single subcutaneous administration, systemic exposure to inclisiran increased in a linear and dose proportional manner over a range from 25 mg to 800 mg of inclisiran sodium. At the recommended dosing regimen of 284 mg of LEQVIO, plasma concentrations reached peak in approximately 4 hours post dose with a mean C max of 509 ng/mL. Concentrations reached undetectable levels after 24 to 48 hours post dosing. The mean area under the plasma concentration-time curve from dosing extrapolated to infinity was 7,980 ng*h/mL. Pharmacokinetic findings following multiple subcutaneous administrations of LEQVIO were similar to single-dose administration. Distribution Inclisiran is 87% protein bound in vitro at the relevant clinical plasma concentrations. Following a single subcutaneous 284 mg dose of LEQVIO to healthy adults, the apparent volume of distribution is approximately 500 L. Inclisiran has been shown to have high uptake into, and selectively for the liver, the target organ for cholesterol lowering. Elimination The terminal elimination half-life of LEQVIO is approximately 9 hours, and no accumulation occurs with multiple dosing. Metabolism Inclisiran is primarily metabolized by nucleases to shorter nucleotides of varying length. Inclisiran is not a substrate for CYP450 or transporters. Excretion Approximately 16% of LEQVIO is cleared through the kidney. Specific Populations Male and Female Patients and Racial or Ethnic Groups A population pharmacodynamic analysis was conducted on data from 4,328 patients. Age, body weight, gender, race, and creatinine clearance were found not to significantly influence inclisiran pharmacokinetics. Pediatric Patients The pharmacokinetics of LEQVIO were evaluated in pediatric patients aged 12 years and older with HeFH (Trial 4) or HoFH (Trial 5) [see Use in Specific Populations (8.4), Clinical Studies (14)] . Inclisiran plasma concentrations in pediatric patients at the clinically recommended dose were similar to adults. Patients with Renal Impairment Pharmacokinetic analysis of data from a dedicated renal impairment study reported increases in inclisiran C max and AUC of approximately 2.3 to 3.3-fold and 1.6 to 2.3-fold, respectively, in patients with mild, moderate or severe renal impairment, relative to patients with normal renal function. Despite the higher plasma exposures, reductions in LDL-C were similar across all groups based on renal function. Patients with Hepatic Impairment Pharmacokinetic analysis of data from a dedicated hepatic impairment study reported increases in inclisiran C max and AUC of approximately 1.1- to 2.1-fold and 1.3- to 2.0-fold, respectively, in patients with mild and moderate hepatic impairment, relative to patients with normal hepatic function. Despite the higher plasma inclisiran exposures, reductions in LDL-C were similar between the groups of patients administered inclisiran with normal hepatic function and mild hepatic impairment. In patients with moderate hepatic impairment, baseline PCSK9 levels were lower and reductions in LDL-C were less than those observed in patients with normal hepatic function. LEQVIO has not been studied in patients with severe hepatic impairment. Drug Interaction Studies No formal clinical drug interaction studies have been performed. The components of LEQVIO are not substrates, inhibitors or inducers of cytochrome P450 enzymes or transporters. In a population pharmacokinetic analysis, concomitant use of inclisiran did not have a clinically significant impact on atorvastatin or rosuvastatin concentrations. LEQVIO is not expected to cause drug-drug interactions or to be affected by inhibitors or inducers of cytochrome P450 enzymes or transporters.
