CLINICAL PHARMACOLOGY SECTION

12 CLINICAL PHARMACOLOGY

12.1 Mechanism of Action

NEXLIZET contains bempedoic acid and ezetimibe. NEXLIZET reduces elevated LDL-C through inhibition of cholesterol synthesis in the liver and absorption in the intestine.

Bempedoic acid

Bempedoic acid is an adenosine triphosphate-citrate lyase (ACL) inhibitor that lowers LDL-C by inhibition of cholesterol synthesis in the liver. ACL is an enzyme upstream of 3-hydroxy-3-methyl-glutaryl-coenzyme A (HMG-CoA) reductase in the cholesterol biosynthesis pathway. Bempedoic acid and its active metabolite, ESP15228, require coenzyme A (CoA) activation by very long-chain acyl-CoA synthetase 1 (ACSVL1) to ETC-1002-CoA and ESP15228-CoA, respectively. ACSVL1 is expressed primarily in the liver. Inhibition of ACL by ETC-1002-CoA results in decreased cholesterol synthesis in the liver and lowers LDL-C in blood via upregulation of low-density lipoprotein receptors.

Ezetimibe

Ezetimibe reduces blood cholesterol by inhibiting the absorption of cholesterol by the small intestine. The molecular target of ezetimibe has been shown to be the sterol transporter, Niemann-Pick C1-Like 1 (NPC1L1), which is involved in the intestinal uptake of cholesterol and phytosterols. Ezetimibe localizes at the brush border of the small intestine and inhibits the absorption of cholesterol, leading to a decrease in the delivery of intestinal cholesterol to the liver. This causes a reduction of hepatic cholesterol stores and an increase in LDL receptors, resulting in clearance of cholesterol from the blood.

12.2 Pharmacodynamics

Administration of bempedoic acid and ezetimibe in combination with other lipid modifying agents, decreases LDL-C, non-high density lipoprotein cholesterol (non-HDL-C), apolipoprotein B (apo B), and total cholesterol (TC) in patients with hyperlipidemia.

Cardiac Electrophysiology

At a dose of 240 mg (1.3 times the approved recommended dose), bempedoic acid does not prolong the QT interval to any clinically relevant extent.

The effect of ezetimibe or NEXLIZET on QT interval has not been evaluated.

12.3 Pharmacokinetics

Absorption

NEXLIZET

The bioavailability of NEXLIZET tablets was similar relative to that from the individual tablets, coadministered. Maximum plasma concentration (Cmax) values for bempedoic acid and its active metabolite (ESP15228) were similar between formulations, but ezetimibe glucuronide and ezetimibe Cmax values were approximately 22% and 13% lower, respectively, for NEXLIZET relative to the individual tablets, coadministered. Given a similar overall extent of ezetimibe glucuronide and ezetimibe exposure (as measured by AUC), a 22% lower Cmax is unlikely to be clinically significant.

Bempedoic acid

Following single oral administration of NEXLIZET (180 mg of bempedoic acid and 10 mg of ezetimibe), mean (± SD) Cmax and AUC of bempedoic acid were 12.6 (± 2.80) µg/mL and 202 (± 43.4) µg.hr/mL, respectively; the median time to maximum concentration (Tmax) was 3.0 hours. Following multiple-dose administration of bempedoic acid monotherapy, the steady-state maximum plasma concentration (Cmax) and AUC at 180 mg/day were 20.6 ± 6.1 µg/mL and 289.0 ± 96.4 µg∙h/mL, respectively. Bempedoic acid steady-state pharmacokinetics were generally linear over a range of >60 mg to 220 mg (approximately 33% to 122% of the recommended dosage of 180 mg daily). There were no time-dependent changes in bempedoic acid pharmacokinetics following repeat administration at the recommended dosage, and bempedoic acid steady-state was achieved after 7 days. The mean accumulation ratio was approximately 2.3-fold.

The steady-state Cmax and AUC of the active metabolite (ESP15228) of bempedoic acid were 2.8 ± 0.9 µg/mL and 51.2 ± 17.2 µg∙h/mL, respectively. ESP15228 likely made a minor contribution to the overall clinical activity of bempedoic acid based on systemic exposure, relative potency, and pharmacokinetic properties.

Ezetimibe

After a single dose of NEXLIZET to fasted adults, mean ± SD ezetimibe Cmax of 3.56 ± 1.90 ng/mL were attained with a median Tmax of 5 hr. Ezetimibe- glucuronide mean Cmax values of 107 ± 46 ng/mL were achieved with a median Tmax of 1 hr. For ezetimibe monotherapy, there was no substantial deviation from dose proportionality between 5 mg and 20 mg (0.5- to 2-fold the recommended dosage). The absolute bioavailability of ezetimibe cannot be determined, as the compound is virtually insoluble in aqueous media suitable for injection.

Effect of Food

NEXLIZET

After the administration of NEXLIZET with a high-fat, high calorie breakfast in healthy subjects, the AUC for bempedoic acid and ezetimibe were comparable to the fasted state. Compared to the fasted state, the fed state resulted in 30% and 12% reductions in Cmax and 2-hour and 2.5-hour delays in median time to attain maximum concentration (Tmax) of bempedoic acid and ezetimibe, respectively. For ezetimibe glucuronide, a 12% and 42% decrease in AUC and Cmax, respectively, were observed under fed relative to fasted conditions.

This effect of food is not considered to be clinically meaningful.

Distribution

Bempedoic acid

The bempedoic acid apparent volume of distribution (V/F) was 18 L. Plasma protein binding of bempedoic acid, its glucuronide and its active metabolite, ESP15228, were 99.3%, 98.8% and 99.2%, respectively. Bempedoic acid does not partition into blood cells.

Ezetimibe

Ezetimibe and ezetimibe-glucuronide are highly bound (>90%) to human plasma proteins.

Elimination

Bempedoic acid

The steady-state clearance (CL/F) of bempedoic acid was 11.2 mL/min after once-daily dosing; renal clearance of unchanged bempedoic acid represented less than 2% of total clearance. The mean ± SD half-life for bempedoic acid in humans was 21 ± 11 hours at steady-state.

Ezetimibe

Both ezetimibe and ezetimibe-glucuronide are eliminated from plasma with a half-life of approximately 22 hours for both.

Metabolism

Bempedoic acid

The primary route of elimination for bempedoic acid is through metabolism to the acyl glucuronide. Bempedoic acid is also reversibly converted to an active metabolite (ESP15228) based on aldo-keto reductase activity observed in vitro from human liver. Mean plasma AUC metabolite/parent drug ratio for ESP15228 following repeat-dose administration was 18% and remained constant over time. Both bempedoic acid and ESP15228 are converted to inactive glucuronide conjugates in vitro by UGT2B7. Bempedoic acid, ESP15228 and their respective conjugated forms were detected in plasma with bempedoic acid accounting for the majority (46%) of the AUC0-48h and its glucuronide being the next most prevalent (30%). ESP15228 and its glucuronide represented 10% and 11% of the plasma AUC0-48h, respectively.

Ezetimibe

Ezetimibe is primarily metabolized in the small intestine and liver via glucuronide conjugation with subsequent biliary and renal excretion. Minimal oxidative metabolism has been observed in all species evaluated.

In humans, ezetimibe is rapidly metabolized to ezetimibe-glucuronide. Ezetimibe and ezetimibe- glucuronide are the major drug-derived compounds detected in plasma, constituting approximately 10% to 20% and 80% to 90% of the total drug in plasma, respectively. Plasma concentration-time profiles exhibit multiple peaks, suggesting enterohepatic recycling.

Excretion

Bempedoic acid

Following single oral administration of 240 mg of bempedoic acid (1.3 times the approved recommended dose), approximately 70% of the total dose (bempedoic acid and its metabolites) was recovered in urine, primarily as the acyl glucuronide conjugate of bempedoic acid, and approximately 30% was recovered in feces. Less than 5% of the administered dose was excreted as unchanged bempedoic acid in feces and urine combined.

Ezetimibe

Following oral administration of 14C-ezetimibe (20 mg) to human subjects, total ezetimibe (ezetimibe + ezetimibe-glucuronide) accounted for approximately 93% of the total radioactivity in plasma. Approximately 78% and 11% of the administered radioactivity were recovered in the feces and urine, respectively, over a 10-day collection period. After 48 hours, there were no detectable levels of radioactivity in the plasma.

Ezetimibe was the major component in feces, and accounted for 69% of the administered dose, while ezetimibe-glucuronide was the major component in urine and accounted for 9% of the administered dose.

Specific Populations

Patients with Renal Impairment

Bempedoic acid

Pharmacokinetics of bempedoic acid was evaluated in a single-dose pharmacokinetic study in subjects with varying degrees of renal function. The mean bempedoic acid AUC in subjects with mild renal impairment (n = 8) were 1.5-fold higher compared to those with normal renal function (n = 6). Relative to those with normal renal function, mean bempedoic acid AUCs were higher in patients with moderate (n = 5) or severe (n = 5) renal impairment by 2.3-fold and 2.4-fold, respectively.

A population pharmacokinetic analysis was performed on pooled data from all clinical trials (n = 2,261) to further evaluate the effects of renal function on the steady-state AUC of bempedoic acid. Compared to patients with normal renal function, the mean bempedoic acid exposures were higher in patients with mild or moderate renal impairment by 1.4-fold (90% CI: 1.3, 1.4) and 1.9-fold (90% CI: 1.7, 2.0), respectively. These differences were not clinically significant. Clinical studies of bempedoic acid did not include patients with severe renal impairment (eGFR <30 mL/min/1.73 m2) or patients with ESRD on dialysis [see Use in Specific Populations (8.6)].

Ezetimibe

After a single 10 mg dose of ezetimibe in patients with severe renal disease (n = 8; mean CrCl ≤ 30 mL/min/1.73 m2), the mean AUC for total ezetimibe, ezetimibe-glucuronide, and ezetimibe increased approximately 1.5-fold, compared to healthy subjects (n = 9). No dosage adjustment is necessary for the ezetimibe component. However, there is limited experience with bempedoic acid in patients with severe renal impairment [see Use in Specific Populations (8.6)].

Patients with Hepatic Impairment

NEXLIZET is not recommended in patients with moderate or severe hepatic impairment due to the unknown effects of the increased exposure to ezetimibe [see Use in Specific Populations (8.7)].

Bempedoic acid

The pharmacokinetics of bempedoic acid and its metabolite (ESP15228) was studied in patients with normal hepatic function or mild or moderate hepatic impairment (Child-Pugh A or B) following a single dose (n = 8/group). Compared to patients with normal hepatic function, the bempedoic acid mean Cmax and AUC were decreased by 11% and 22%, respectively, in patients with mild hepatic impairment and by 14% and 16%, respectively, in patients with moderate hepatic impairment. Compared to patients with normal hepatic function, the ESP15228 mean Cmax and AUC were decreased by 13% and 23%, respectively, in patients with mild hepatic impairment and by 24% and 36%, respectively, in patients with moderate hepatic impairment. This is not expected to result in lower efficacy.

Bempedoic acid was not studied in patients with severe hepatic impairment (Child-Pugh C).

Ezetimibe

After a single 10 mg dose of ezetimibe, the mean AUC for total ezetimibe increased approximately 1.7-fold in patients with mild hepatic impairment (Child-Pugh score 5 to 6), compared to healthy subjects. The mean AUC values for total ezetimibe and ezetimibe increased approximately 3- to 4-fold and 5- to 6-fold, respectively, in patients with moderate (Child-Pugh score 7 to 9) or severe hepatic impairment (Child-Pugh score 10 to 15). In a 14-day, multiple-dose study (10 mg daily) in patients with moderate hepatic impairment, the mean AUC for total ezetimibe and ezetimibe increased approximately 4-fold on day 1 and day 14 compared to healthy subjects.

Other Specific Populations

Bempedoic acid

The pharmacokinetics of bempedoic acid were not affected by age, gender, race, or weight.

Ezetimibe

Geriatrics: In a multiple-dose study with ezetimibe given 10 mg once daily for 10 days, plasma concentrations for total ezetimibe were about 2-fold higher in older (≥ 65 years) healthy subjects compared to younger subjects [see Use in Specific Populations (8.5)].

Gender: In a multiple-dose study with ezetimibe given 10 mg once daily for 10 days, plasma concentrations for total ezetimibe were slightly higher (<20%) in females than in males.

Race: The pharmacokinetics of ezetimibe is not affected by race.

Drug Interaction Studies

Bempedoic acid

Cytochrome P450 Substrates

In vitro metabolic interaction studies suggest that bempedoic acid, as well as its active metabolite and glucuronide forms are not metabolized by and do not interact with cytochrome P450 enzymes.

Transporter-mediated Drug Interactions

In vitro drug interaction studies suggest bempedoic acid, as well as its active metabolite and glucuronide form, are not substrates of commonly characterized drug transporters with the exception of bempedoic acid glucuronide, which is an OAT3 substrate. Bempedoic acid weakly inhibits OAT3 at high multiples of clinically relevant concentrations, and bempedoic acid and its glucuronide weakly inhibit OATP1B1, and OATP1B3 at clinically relevant concentrations. Bempedoic acid weakly inhibits OAT2 in vitro, which is likely the mechanism responsible for minor elevations in serum creatinine and uric acid [see Adverse Reactions (6.1)].

Probenecid

Administration of bempedoic acid 180 mg with steady-state probenecid resulted in a 1.7- and a 1.2-fold increase in bempedoic acid AUC and Cmax, respectively. AUC and Cmax for bempedoic acid active metabolite (ESP15228) were increased 1.9- and 1.5-fold, respectively. These elevations are not clinically meaningful and do not impact dosing recommendations.

Statins

The pharmacokinetic interactions between bempedoic acid (at systemic exposure relevant to the indicated CVD population) and simvastatin 20 mg, atorvastatin 10 mg, pravastatin 40 mg, and rosuvastatin 10 mg were evaluated in clinical trials.

Simvastatin: Administration of simvastatin 20 mg with 240 mg of bempedoic acid or 40 mg with 180 mg of bempedoic acid in healthy subjects at steady-state resulted in approximately 2-fold (91% for 20 mg and 96% for 40 mg) and 1.5-fold (54% for 20 mg and 52% for 40 mg) increases in simvastatin acid AUC and Cmax, respectively [see Drug Interactions (7)].

Pravastatin: Administration of pravastatin 40 mg with steady-state bempedoic acid 240 mg in healthy subjects resulted in 99% (2-fold) and 104% (2-fold) increases in pravastatin acid AUC and Cmax, respectively [see Drug Interactions (7)].

Atorvastatin and Rosuvastatin: Elevations of 1.7-fold in AUC of atorvastatin, and rosuvastatin and/or their major metabolites were observed, suggesting a weak interaction. These elevations were generally within the individual statin exposures and do not impact dosing recommendations.

Warfarin

In vitro studies indicate that bempedoic acid is not an inhibitor or inducer of CYP2C9. Because warfarin is primarily eliminated through CYP2C9, its pharmacokinetics is not expected to be altered by bempedoic acid.

Other

Bempedoic acid had no effect on the pharmacokinetics of metformin or the oral contraceptive Ortho-Novum 1/35.

Ezetimibe

Ezetimibe had no significant effect on a series of probe drugs (caffeine, dextromethorphan, tolbutamide, and IV midazolam) known to be metabolized by cytochrome P450 (1A2, 2D6, 2C8/9 and 3A4) in a "cocktail" study of twelve healthy adult males. This indicates that ezetimibe is neither an inhibitor nor an inducer of these cytochrome P450 isozymes, and it is unlikely that ezetimibe will affect the metabolism of drugs that are metabolized by these enzymes.

Cyclosporine: Administration of ezetimibe with cyclosporine (75–150 mg BID) resulted in a 2.4- and a 2.9-fold increase in total ezetimibe AUC and Cmax, respectively [see Drug Interactions (7)].

Fibrates: Administration of ezetimibe with fenofibrate (200 mg QD for 14 days) resulted in a 1.48- and a 1.64-fold increase in total ezetimibe AUC and Cmax, respectively. Administration with gemfibrozil (600 mg BID for 7 days) resulted in a 1.64- and 1.91-fold increase in total ezetimibe AUC and Cmax, respectively [see Drug Interactions (7)].

Cholestyramine: Administration of ezetimibe with cholestyramine (4 g BID for 14 days) resulted in a 55% and a 4% decrease in total ezetimibe AUC and Cmax, respectively [see Drug Interactions (7)].

No clinically meaningful pharmacokinetic interaction was observed following coadministration of ezetimibe with aluminum & magnesium hydroxide combination antacid, cimetidine, glipizide, lovastatin, pravastatin, atorvastatin, rosuvastatin, fluvastatin, simvastatin, digoxin, ethinyl estradiol/levonorgestrel, and warfarin.

Tendon Rupture: Tendon rupture has occurred. Discontinue NEXLIZET at the first sign of tendon rupture. Avoid NEXLIZET in patients who have a history of tendon disorders or tendon rupture. (5.2)

5 WARNINGS AND PRECAUTIONS

5.1 Hyperuricemia

Bempedoic acid, a component of NEXLIZET, inhibits renal tubular OAT2 and may increase blood uric acid levels [see Clinical Pharmacology (12.3)]. In the primary hyperlipidemia trials [see Clinical Studies (14.1)], 26% of bempedoic acid-treated patients with normal baseline uric acid values (versus 9.5% placebo) experienced hyperuricemia one or more times, and 3.5% of patients experienced clinically significant hyperuricemia reported as an adverse reaction (versus 1.1% placebo). Increases in uric acid levels usually occurred within the first 4 weeks of treatment initiation, persisted throughout treatment, and returned to baseline following discontinuation of treatment. After 12 weeks of treatment, the mean placebo-adjusted increase in uric acid compared to baseline was 0.8 mg/dL for patients treated with bempedoic acid. In the cardiovascular outcomes trial [see Clinical Studies (14.2)], 16.4% of bempedoic acid-treated patients experienced clinically significant hyperuricemia reported as an adverse reaction (versus 8.2% placebo).

Elevated blood uric acid may lead to the development of gout. In the primary hyperlipidemia trials, gout was reported in 1.5% of patients treated with bempedoic acid versus 0.4% of patients treated with placebo. In the cardiovascular outcomes trial, gout was reported in 3.2% of patients treated with bempedoic acid and 2.2% treated with placebo.

Advise patients to contact their healthcare provider if symptoms of hyperuricemia occur. Assess serum uric acid when clinically indicated. Monitor patients for signs and symptoms of hyperuricemia, and initiate treatment with urate-lowering drugs as appropriate.

5.2 Tendon Rupture

Bempedoic acid, a component of NEXLIZET, is associated with an increased risk of tendon rupture or injury. In the primary hyperlipidemia trials [see Clinical Studies (14.1)], tendon rupture occurred in 0.5% of patients treated with bempedoic acid versus 0% of placebo-treated patients and involved the rotator cuff (the shoulder), biceps tendon, or Achilles tendon. Tendon rupture occurred within weeks to months of starting bempedoic acid. In the cardiovascular outcomes trial [see Clinical Studies (14.2)], tendon rupture events occurred in 1.2% of bempedoic acid-treated patients versus 0.9% of placebo-treated patients. Tendon rupture may occur more frequently in patients over 60 years of age, in those taking corticosteroid or fluoroquinolone drugs, in patients with renal failure, and in patients with previous tendon disorders.

Discontinue NEXLIZET immediately if the patient experiences rupture of a tendon. Consider discontinuing NEXLIZET if the patient experiences joint pain, swelling, or inflammation. Advise patients to rest at the first sign of tendinitis or tendon rupture and to contact their healthcare provider if tendinitis or tendon rupture symptoms occur. Consider alternative therapy in patients with a history of tendon disorders or tendon rupture.

6 ADVERSE REACTIONS

The following clinically significant adverse reactions are described elsewhere in the labeling:

• Hyperuricemia [see Warnings and Precautions (5.1)]
• Tendon Rupture [see Warnings and Precautions (5.2)]

6.1 Clinical Trials Experience

Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in clinical practice.

Bempedoic acid

The data in Table 1 reflect exposure to bempedoic acid in two placebo- controlled primary hyperlipidemia trials that included 2,009 patients treated with bempedoic acid for 52 weeks (median treatment duration of 52 weeks) [see Clinical Studies (14.1)]. The mean age for bempedoic acid-treated patients was 65 years, 29% were female, 95% were White, 3% were Black or African American, 1% were Asian, and 1% were other races; 3% identified as Hispanic or Latino ethnicity. All patients received bempedoic acid 180 mg orally once daily plus maximally tolerated statin therapy alone or in combination with other lipid- lowering therapies. At baseline, 97% of patients had CVD and about 4% had a diagnosis of HeFH. Patients on simvastatin 40 mg/day or higher were excluded from the trials.

In the primary hyperlipidemia trials, adverse reactions led to discontinuation of treatment in 11% of bempedoic acid-treated patients and 8% of placebo- treated patients. The most common reasons for bempedoic acid treatment discontinuation were muscle spasms (0.5% versus 0.3% placebo), diarrhea (0.4% versus 0.1% placebo), and pain in extremity (0.3% versus 0.0% placebo). Adverse reactions reported in at least 2% of bempedoic acid-treated patients and more frequently than in placebo-treated patients are shown in Table 1.

Table 1. Adverse Reactions (≥ 2% and greater than placebo) in Bempedoic Acid-Treated Patients with Primary Hyperlipidemia and CVD or HeFH (Trials 2 and 3)

In the cardiovascular outcomes trial in which 7,001 patients were exposed to bempedoic acid and 6,964 patients were exposed to placebo for a median of 3.1 years [see Clinical Studies (14.2)], adverse reactions led to discontinuation of treatment in 11% of bempedoic acid-treated patients and 10% of placebo- treated patients. Adverse reactions reported in at least 2% of bempedoic acid- treated patients and more frequently than placebo are shown in Table 2.

Table 2. Adverse Reactions (≥ 2% and 0.5% greater than placebo) in Bempedoic Acid-Treated Patients with CVD or at High Risk for CVD (Trial 4)

Other Adverse Reactions

Tendon Rupture

In the hyperlipidemia trials, tendon rupture occurred in 0.5% of bempedoic acid-treated patients versus 0% of placebo-treated patients. In the cardiovascular outcomes trial, tendon rupture events occurred in 1.2% of bempedoic acid-treated patients versus 0.9% of placebo-treated patients.

Gout

In the hyperlipidemia trials, gout occurred in 1.5% of bempedoic acid-treated patients versus 0.4% of placebo-treated patients. In the cardiovascular outcomes trial, gout occurred in 3.2% of bempedoic acid-treated patients versus 2.2% of placebo-treated patients.

Laboratory Tests

Bempedoic acid was associated with persistent changes in multiple laboratory tests that occurred within the first 4 weeks of treatment, and returned to baseline following discontinuation of treatment.

Increase in Creatinine and Blood Urea Nitrogen

In the hyperlipidemia trials, there was a mean increase in serum creatinine of 0.05 mg/dL compared to baseline with bempedoic acid at Week 12. Approximately 3.8% of patients treated with bempedoic acid had blood urea nitrogen values that doubled (versus 1.5% placebo), and about 2.2% of patients had creatinine values that increased by 0.5 mg/dL (versus 1.1% placebo). In the cardiovascular outcomes trial, 7.1% of patients had creatinine values that increased by 0.5 mg/dL (versus 5.5% placebo) and 9.5% of patients in the bempedoic acid group had BUN values that increased ≥ 2× baseline (versus 6.2% placebo).

Decrease in Hemoglobin and Leukocytes

In the hyperlipidemia trials, approximately 5.1% of patients treated with bempedoic acid (versus 2.3% placebo) had decreases in hemoglobin levels of 2 or more g/dL and below the lower limit of normal on one or more occasion. Anemia was reported in 2.8% of patients treated with bempedoic acid and 1.9% of patients treated with placebo. Approximately 9.0% of bempedoic acid-treated patients with normal baseline leukocyte count had a decrease to less than the lower limit of normal on one or more occasion (versus 6.7% placebo). Leukocyte decrease was generally asymptomatic and did not require medical intervention. In the hyperlipidemia trials, there was a small imbalance in skin or soft tissue infections, including cellulitis (0.8% versus 0.4%), but there was no imbalance in other infections.

In the cardiovascular outcomes trial, 10.8% of patients (versus 7.4% placebo) had a decrease in hemoglobin of 2 or more g/dL and below the lower limit of normal. Anemia was reported in 4.7% of patients treated with bempedoic acid and 3.9% of patients treated with placebo. There were 9.3% of bempedoic acid- treated patients with a leukocyte count below the lower limit of normal (and normal at baseline) at any point (versus 6.8% placebo).

Increase in Platelet Count

In the hyperlipidemia trials, approximately 10.1% of bempedoic acid-treated patients (versus 4.7% placebo) had increases in platelet counts of 100× 109/L or more on one or more occasion. In the cardiovascular outcomes trial, 18.6% of patients in the bempedoic acid-treated group (versus 10.2% placebo) had an increase in platelet count of 100 × 109/L or more. Platelet count increase was asymptomatic and did not result in increased risk for thromboembolic events.

Increase in Liver Enzymes

In the hyperlipidemia trials, increases in hepatic transaminases (AST and/or ALT) were observed with bempedoic acid. In most cases, the elevations were transient and resolved or improved with continued therapy or after discontinuation of therapy. Increases to more than 3× the upper limit of normal (ULN) in AST occurred in 1.4% of patients treated with bempedoic acid versus 0.4% of placebo patients, and increases to more than 5× ULN occurred in 0.4% of bempedoic acid- treated versus 0.2% of placebo-treated patients. Increases in ALT occurred with similar incidence between bempedoic acid- and placebo-treated patients. Elevations in transaminases were generally asymptomatic and not associated with elevations ≥ 2× ULN in bilirubin or with cholestasis.

In the cardiovascular outcomes trial, the incidence of repeated and confirmed ALT and/or AST >3× ULN was 1.6% in the bempedoic acid-treated group (versus 1.0% placebo). A higher percentage of patients in the bempedoic acid-treated group had hepatic enzyme elevations versus placebo (4.5% versus 3.0%, respectively).

Increase in Creatine Kinase

In the hyperlipidemia trials, approximately 1.0% of patients (versus 0.6% placebo) had elevations of CK levels of 5 or more times the normal value on one or more occasions, and 0.4% of patients (versus 0.2% placebo) had elevations of CK levels of 10 or more times.

Ezetimibe

In 10 double-blind, placebo-controlled clinical trials [see Clinical Studies (14.1)], 2,396 patients with primary hyperlipidemia (age range 9 to 86 years, 50% were female, 90% were White, 5% were Black or African American, 2% were Asian, 3% other races; 3% identified as Hispanic or Latino ethnicity) and elevated LDL-C were treated with ezetimibe 10 mg/day for a median treatment duration of 12 weeks (range 0 to 39 weeks).

Adverse reactions reported in ≥ 2% of patients treated with ezetimibe and at an incidence greater than placebo in placebo-controlled studies of ezetimibe are shown in Table 3.

Table 3. Adverse Reactions Occurring in ≥ 2% and greater than placebo in Ezetimibe-treated Patients

NEXLIZET

In a 4-arm, 12-week, randomized, double-blind, placebo-controlled, parallel group, factorial trial, 85 patients received NEXLIZET (180 mg of bempedoic acid and 10 mg of ezetimibe) once daily [see Clinical Studies (14.1)]. The mean age for NEXLIZET-treated patients was 62 years, 51% were female, 78% were White, 19% were Black or African American, 2% were Asian, and 1% were American Indian or Alaska Native; 11% identified as Hispanic or Latino ethnicity. At baseline, 61% of patients had CVD and/or a diagnosis of HeFH. All patients received NEXLIZET plus maximally tolerated statin therapy. Patients taking simvastatin 40 mg/day or higher and patients taking non-statin lipid-lowering therapy (including fibrates, niacin, bile acid sequestrants, ezetimibe, and PCSK9 inhibitors) were excluded from the trial.

Adverse reactions led to discontinuation of treatment in 8% of patients on NEXLIZET, 5% of patients on placebo, 10% of patients on bempedoic acid, and 12% of patients on ezetimibe. The most common reason for NEXLIZET treatment discontinuation was oral discomfort (2% NEXLIZET versus 0% placebo). The most commonly reported adverse reactions (incidence ≥ 3% and greater than placebo) observed with NEXLIZET, but not observed in clinical trials of bempedoic acid or ezetimibe, were urinary tract infection (5.9% NEXLIZET versus 2.4% placebo), nasopharyngitis (4.7% NEXLIZET versus 0% placebo), and constipation (4.7% NEXLIZET versus 0% placebo).

6.2 Postmarketing Experience

The following additional adverse reactions have been reported in postmarketing experience for ezetimibe and/or bempedoic acid. 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.

Blood Disorders: thrombocytopenia

Gastrointestinal Disorders: abdominal pain; pancreatitis; nausea

Hepatobiliary Disorders: elevations in liver transaminases, including elevations more than 5× ULN; hepatitis; cholelithiasis; cholecystitis

Immune System Disorders: Hypersensitivity reactions including: anaphylaxis, angioedema, wheezing, rash, and urticaria

Musculoskeletal Disorders: elevated creatine phosphokinase; myopathy/rhabdomyolysis

Nervous System Disorders: dizziness; paresthesia; depression; headache

Skin and Subcutaneous Tissue Disorders: erythema multiforme

CLINICAL STUDIES SECTION

14 CLINICAL STUDIES

14.1 Primary Hyperlipidemia Trials in Adults

The efficacy of NEXLIZET was investigated in a single, multi-center, randomized, double-blind, placebo-controlled, parallel group trial that enrolled 301 patients with HeFH, established CVD, or multiple risk factors for CVD on maximally tolerated statin therapy. The efficacy of NEXLIZET in patients with multiple risk factors for cardiovascular disease has not been established.

Trial 1 (NCT03337308) was a 4-arm, 12-week trial that assessed the efficacy of NEXLIZET in 301 patients randomized 2:2:2:1 to receive either oral NEXLIZET (180 mg of bempedoic acid and 10 mg of ezetimibe) (n = 86), bempedoic acid 180 mg (n = 88), ezetimibe 10 mg (n = 86), or placebo (n = 41) once daily as add- on to maximally tolerated statin therapy. Patients were stratified by cardiovascular risk and baseline statin intensity. Patients on simvastatin 40 mg per day or higher and patients taking non-statin lipid-lowering therapy (including fibrates, niacin, bile acid sequestrants, ezetimibe, and PCSK9 inhibitors) were excluded from the trial.

Baseline Demographics and Disease Characteristics: Overall, the mean age at baseline was 64 years (range: 30 to 87 years), 50% were 65 years of age and older, 50% were female, 81% were White, 17% were Black or African American, 1% were Asian, and 1% were other races; 12% identified as Hispanic or Latino ethnicity. Sixty-two percent (62%) of patients had clinical CVD and/or a diagnosis of HeFH. The mean baseline LDL-C was 149.7 mg/dL. At the time of randomization, 65% of patients were receiving statin therapy; and 35% were receiving high intensity statin therapy.

Efficacy Results: The primary efficacy outcome measure of the study was the percent change from baseline to Week 12 in LDL-C. The difference between NEXLIZET and placebo in mean percent change in LDL-C from baseline to Week 12 was -38% (95% CI: -47%, -30%; p <0.001). High-density lipoprotein (HDL) and triglycerides (TG) were examined as exploratory endpoints and were not included in the statistical hierarchy. The difference between NEXLIZET and placebo in mean percent change from baseline to Week 12 was -5% for HDL and median percent change from baseline to Week 12 was -11% for TG. The maximum LDL-C lowering effect was observed at Week 4. For additional results see Table 5.

Examination of age, sex, and race subgroups did not identify differences in response to NEXLIZET among these subgroups in any of the trials.

Bempedoic Acid

Primary Hyperlipidemia

In the two primary hyperlipidemia (52-week) trials (Trials 2 and 3) that included 3,009 adult patients with HeFH or established CVD on maximally tolerated statin therapy, the difference between bempedoic acid and placebo in mean percent change in LDL-C from baseline to Week 12 was -17% to -18%. Bempedoic acid also significantly lowered non-HDL-C (-13%), apo B (-12% to -13%), and TC (-11%) compared with placebo.

Ezetimibe

Ezetimibe Added to On-going Statin Therapy: In a multicenter, double-blind, placebo-controlled, 8-week trial, 769 patients (age range 22 to 85 years, 42% were females; 90% were White, 6% were Black or African American, 1% were Asian, and 3% were other races; 2% identified as Hispanic or Latino ethnicity) with primary hyperlipidemia, known coronary heart disease or multiple cardiovascular risk factors who were already receiving statin monotherapy, but who had not met their NCEP ATP II target LDL-C goal, were randomized to receive either ezetimibe or placebo in addition to their on-going statin therapy.

Ezetimibe, added to on-going statin therapy, significantly lowered TC (-17%), LDL-C (-25%), apo B (-19%), and non-HDL-C (-23%) relative to baseline and compared with a statin administered alone. LDL-C reductions induced by ezetimibe were generally consistent across all statins.

Ezetimibe Initiated Concurrently with a Statin: In four, multicenter, double- blind, placebo-controlled, 12-week trials, in 2,382 patients (age range 18 to 87 years, 57% were female; 88% were White, 5% were Black or African American, 2% were Asian, and 5% were other races mostly identified as Hispanic or Latino ethnicity) with hyperlipidemia, ezetimibe or placebo was orally administered alone or with various doses of atorvastatin, simvastatin, pravastatin, or lovastatin. When all patients receiving ezetimibe with a statin were compared to all those receiving the corresponding statin alone, ezetimibe significantly lowered LDL-C (ezetimibe + all atorvastatin doses [-56%] versus all atorvastatin doses alone [-44%]; ezetimibe + all simvastatin doses [-51%] versus all simvastatin doses alone [-36%]; ezetimibe + all pravastatin doses [-39%] versus all pravastatin doses alone [-25%]; ezetimibe + all lovastatin doses [-40%] versus all lovastatin doses alone [-25%]). LDL-C reductions induced by ezetimibe were generally consistent across all statins.

14.2 Cardiovascular Outcomes Trial in Adults With CVD or at High Risk for

CVD

Trial 4 (NCT02993406) was a randomized, double-blind, placebo-controlled, event-driven trial in 13,970 adult patients with established CVD (70%) or at high risk for a CVD event but without CVD (30%) who were not receiving recommended statin dosages. Patients with established CVD had documented history of coronary artery disease, symptomatic peripheral arterial disease, and/or cerebrovascular atherosclerotic disease. Patients without established CVD were considered at high risk for CVD based on meeting at least one of the following criteria:

(1) Diabetes mellitus (type 1 or type 2) in females over 65 years of age or males over 60 years of age;  

(2) A Reynolds Risk score > 30% or a SCORE Risk score > 7.5% over 10 years. Reynolds risk score and SCORE risk score evaluate a 10-year risk of having a cardiovascular (CV) event. The Reynolds risk score is based on the following risk factors: sex, age, smoking status, systolic blood pressure, total cholesterol, HDL cholesterol, high sensitivity C-reactive protein (hsCRP), and familial history of CVD events. LDL-C is an additional risk factor considered in SCORE risk score; or
(3) A coronary artery calcium score >400 Agatston units at any time in the past.

Patients were randomized 1:1 to receive either oral bempedoic acid 180 mg per day (n = 6,992) or placebo (n = 6,978), alone or as an add on to other background lipid-lowering therapies. Background therapy could include less than low-intensity statin dosages. Overall, 95.3% of adult patients were followed until the end of the trial or death. The median follow-up duration was 3.4 years.

Baseline Demographics and Disease Characteristics

At baseline, the mean age was 66 years (range 21 to 92 years), 59% were 65 years of age and older, 15% were 75 years of age and older, 48% were female, 91% were White, 2% were Black or African American, 4% were American Indian or Alaska Native, 2% were Asian, and 1% were other races; 17% identified as Hispanic or Latino ethnicity.

Selected additional baseline characteristics included hypertension (85%), diabetes mellitus (46%), current tobacco user (22%), eGFR < 60 mL/min per 1.73 m2 (21%), and a mean body mass index of 30 kg/m2. The mean baseline LDL-C was 139 mg/dL. At baseline, 38% of patients were taking at least one lipid modifying therapy including less than low-intensity statin dosages (23%), ezetimibe (12%), or fibrates (5%). Most patients were taking at least one other CV medication including acetylsalicylic acid (57%), selective beta blockers (52%), angiotensin converting enzyme inhibitors (40%), or angiotensin receptor blockers (32%).

Efficacy Results

The risk for the primary composite endpoint (MACE-4: time to first occurrence of CV death, nonfatal myocardial infarction, nonfatal stroke, or coronary revascularization; p= 0.0037) and the key secondary composite endpoint (MACE-3: time to first occurrence of CV death, nonfatal myocardial infarction, or nonfatal stroke; p= 0.0058) was significantly reduced in bempedoic acid- treated patients compared to the placebo-treated patients (Table 6). The difference between bempedoic acid and placebo in mean percent change in LDL-C from baseline to Month 6 was -20% (95% CI: -21%, -19%).
