Lerochol Injection, Solution - FDA Label NDC 84685-300

1 Indications And Usage

LEROCHOL^TM is indicated as an adjunct to diet and exercise to reduce low-density lipoprotein cholesterol (LDL-C) in adults with hypercholesterolemia, including heterozygous familial hypercholesterolemia (HeFH).

2.1 Recommended Dosage

The recommended dosage of LEROCHOL is 300 mg once monthly administered subcutaneously.
Assess LDL-C when clinically indicated. The LDL-lowering effect of LEROCHOL may be measured as early as 4 weeks after initiation and, provided monthly dosing is continued, anytime thereafter without regard to timing of the dose.

2.2 Recommendations Regarding Missed Dose(S)

If a dose is missed by:
- Less than 7 days, instruct the patient to administer LEROCHOL as soon as possible and resume the patient's original monthly dosage schedule.
- Seven (7) or more days, instruct the patient to administer LEROCHOL as soon as possible and start a new monthly dosage schedule based on this date.

2.3 Important Administration Instructions

Train patients and/or their caregivers on how to prepare and administer LEROCHOL, according to the Instructions for Use, and instruct them to read and follow the Instructions for Use each time they use LEROCHOL.
Prior to use, allow LEROCHOL to warm to room temperature up to 25°C (77°F) for at least 30 minutes if LEROCHOL has been refrigerated [see How Supplied/Storage and Handling (16)].
Visually inspect LEROCHOL prior to administration. LEROCHOL is a clear to slightly opalescent, brownish-yellow to amber solution. Do not use if the solution is cloudy or contains particles.
Inject LEROCHOL subcutaneously into the abdomen or the upper front thighs. If injected by a healthcare professional or caregiver, the back of the upper arms can also be a site of injection [see Instructions for Use]. Do not inject in an area of the skin that is tender, bruised, red, or indurated. Rotate injection sites for each administration.
To administer the full 300 mg dose, push plunger down until the syringe is empty before removing from the injection site.

3 Dosage Forms And Strengths

Injection: 300 mg/1.2 mL (250 mg/mL) of clear to slightly opalescent, brownish-yellow to amber solution in a single-dose prefilled syringe.

4 Contraindications

None.

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 practice.

Adverse Reactions in Adults with Primary Hypercholesterolemia

Adverse Reactions in Two Pooled 52-week Controlled Trials

In two pooled 52-week, double-blind, randomized, placebo-controlled trials (Trials 1 and 2), 1,229 patients received 300 mg of LEROCHOL subcutaneously every 4 weeks [see Clinical Studies (14)]. The mean age was 64 years (range 25 to 90 years), 52% were 65 years of age or older, 37% female, 79% White, 18% Black or African American, 4% Asian; 7% identified as Hispanic or Latino ethnicity. At baseline, 9% of patients had a diagnosis of HeFH, 74% had established atherosclerotic cardiovascular disease (ASCVD), and 26% were at increased risk for ASCVD. Adverse reactions reported in at least 2% of LEROCHOL-treated patients and more frequently than in placebo-treated patients are shown in Table 1. Adverse reactions led to treatment discontinuation in 4% of LEROCHOL-treated patients and placebo-treated patients. The most frequent adverse reaction leading to treatment discontinuation was injection site reactions, with a higher frequency in the LEROCHOL-treated group compared to placebo-treated patients (1% vs. 0%).

Risk Summary

Discontinue LEROCHOL when pregnancy is recognized. Alternatively, consider the ongoing therapeutic needs of the individual patient. LEROCHOL increases LDL-C uptake and lowers LDL-C levels in the circulation, thus decreasing cholesterol and possibly other biologically active substances derived from cholesterol; therefore, LEROCHOL may cause fetal harm when administered to pregnant patients based on the mechanism of action [see Clinical Pharmacology (12.1)]. In addition, treatment of hypercholesterolemia is not generally necessary during pregnancy. Atherosclerosis is a chronic process and the discontinuation of lipid-lowering drugs during pregnancy should have little impact on the outcome of long-term therapy of primary hypercholesterolemia for most patients.

Available data from clinical trials on LEROCHOL use in pregnant women are insufficient to evaluate for a drug-associated risk of major birth defects, miscarriage or other adverse maternal or fetal outcomes.

In animal reproduction studies, there were no adverse developmental effects observed when pregnant monkeys were administered lerodalcibep-liga subcutaneously during organogenesis and through to parturition at doses up to 100 mg/kg/week [up to 119-fold the exposure at the maximum recommended human dose (MRHD) of 300 mg every month].

The background risk of major birth defects and miscarriage for the indicated population is unknown. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2% to 4% and 15% to 20%, respectively.

Data

Animal Data

In cynomolgus monkeys, no effects on embryo-fetal or postnatal development (up to 6 months of age) were observed when lerodalcibep-liga was dosed during organogenesis and through parturition at 30 and 100 mg/kg subcutaneously once weekly (exposures up to 119-fold the MRHD by AUC). An assessment of immune function in the infants showed no treatment-related adverse effects. Measurable lerodalcibep-liga serum concentrations were observed in the infant monkeys with infant serum concentrations approximately 2 to 7% of maternal serum concentrations on postnatal days 14, 21 and 28, indicating that lerodalcibep-liga has the potential to be transmitted from the mother to the developing fetus.

Risk Summary

There are no data on the presence of lerodalcebip-liga in human milk, the effects on the breastfed infant, or the effects on milk production. In animal reproduction studies, lerodalcibep-liga was present in the milk of lactating monkeys (see Data). When a drug is present in animal milk, it is likely that the drug will be present in human milk. The developmental and health benefits of breastfeeding should be considered along with the mother's clinical need for LEROCHOL and any potential adverse effects on the breastfed infant from LEROCHOL or from the underlying maternal condition.

Data

Low concentrations of lerodalcibep-liga were measured in milk samples collected from monkeys on post-partum day (PPD) 7 and PPD 14, when lerodalcibep-liga was dosed during organogenesis through parturition at 30 and 100 mg/kg subcutaneously once weekly (exposures up to 119-fold the MRHD by AUC). There is no information regarding whether lerodalcibep-liga ingested with milk transfers to neonatal or infant monkey circulation.

Absorption

The median (min, max) estimated subcutaneous bioavailability of lerodalcibep-liga is 83% (66%, 89%). The median (min, max) time to maximum plasma concentration (Tmax) is 6 days (2, 9 days) at steady state.

Distribution

Lerodalcibep-liga does not extensively distribute into tissues; the apparent volume of distribution is 5.3 L.

Elimination

As a protein, lerodalcibep-liga is expected to degrade to small peptides and amino acids. Clearance of free lerodalcibep-liga (CV%) is 0.36 L/day (30%) with an estimated half-life of approximately 10 days. The estimated elimination rate of lerodalcibep-liga (CV%) bound to PCSK9 is 0.47 L/day (22%) which corresponds to a half-life of approximately 1.5 days.

Specific Populations

No clinically significant differences in the pharmacokinetics of LEROCHOL were observed based on age (21 to 78 years), body weight, sex, race, mild (eGFR 60 to 89 mL/min) or moderate (eGFR 30 to 59 mL/min) renal impairment, or mild (total bilirubin 1.0 to 1.5 upper limit of normal or aspartate aminotransaminase greater than the upper limit of normal) or moderate (total bilirubin 1.5 to 3.0 upper limit of normal) hepatic impairment. The effect of severe renal impairment (eGFR less than 30 mL/min) or severe hepatic impairment on LEROCHOL pharmacokinetics is unknown.

Drug Interaction Studies

No formal clinical drug interaction studies have been performed.

Primary Hypercholesterolemia

Trial 1 (NCT04797247) and Trial 2 (NCT04806893) were both multicenter, double-blind, randomized, placebo-controlled 52-week trials in which 1,844 adults with ASCVD or at increased risk for ASCVD events were randomized 2:1 to receive subcutaneous injections of either LEROCHOL 300 mg (n=1,229) or placebo (n=615) every 4 weeks. Patients were stable on a low-fat, low-cholesterol diet, maximally tolerated dose of statin with or without other oral lipid modifying therapy, and required additional LDL-C reduction.

Baseline Disease and Demographic Characteristics

The mean age in Trial 1 at baseline was 64 years (range: 25 to 90 years), 49% were 65 years or older, 30% were female, 80% were White, 17% were Black or African American, and 3% were Asian; 1.1% identified as Hispanic or Latino ethnicity. Thirty four percent (34%) of patients had diabetes at baseline, 86% established ASCVD, and 14% at increased risk for CVD events. The mean baseline LDL-C was 102 mg/dL. At the time of randomization, 87% of patients were receiving statin therapy and of these 53% were receiving high-intensity statin therapy; 18% were receiving ezetimibe either in combination with a statin or alone.

The mean age in Trial 2 at baseline was 65 years (range: 27 to 87 years), 54% were 65 years or older, 45% were female, 78% were White, 18% were Black or African American, and 4% were Asian; 13% identified as Hispanic or Latino ethnicity. Forty-three percent (43%) of patients had diabetes at baseline, 48% established ASCVD, and 52% at increased risk for CVD events. The mean baseline LDL-C was 116 mg/dL. At the time of randomization, 83% of patients were receiving statin therapy and of these, 39% were on high-intensity doses; 17% were receiving ezetimibe either in combination with a statin or alone.

Endpoint Results

The primary efficacy outcome measure in Trial 1 was the placebo adjusted intent to treat (ITT) analysis of percent change in LDL-C from baseline to Week 52. The difference between the LEROCHOL and placebo group in mean percentage change in LDL-C from baseline to Week 52 was -55% (95% CI: -59.2%, -50.8%; p < 0.0001). For additional results, see Table 3 and Figure 1.

8.4 Pediatric Use

The safety and effectiveness of LEROCHOL in pediatric patients have not been established. Clinical trials of LEROCHOL in pediatric patients with HeFH have not been conducted. Effectiveness of LEROCHOL was not demonstrated in a 24-week, randomized, open-label, active-controlled trial (NCT04034485) in 19 pediatric patients aged 10 to 17 years with homozygous familial hypercholesterolemia (HoFH).

8.5 Geriatric Use

Of the 1,631 patients treated with LEROCHOL 300 mg in clinical trials, 687 (42%) patients were 65 years of age and older, while 198 (12%) patients were 75 years of age or older. No overall differences in safety or effectiveness were observed between patients 65 years of age and older and younger adult patients.

8.6 Renal Impairment

No dose adjustment is necessary in patients with mild to moderate renal impairment [estimated glomerular filtration rate (eGFR) ≥30 to <90 mL/min] [see Clinical Pharmacology (12.3)]. LEROCHOL has not been studied in patients with severe renal impairment (eGFR < 30 mL/min) or end-stage renal disease.

8.7 Hepatic Impairment

No dose adjustment is necessary in patients with mild (total bilirubin 1.0 to 1.5 upper limit of normal or aspartate aminotransaminase > upper limit of normal) or moderate (total bilirubin 1.5 to 3.0 upper limit of normal) hepatic impairment [see Clinical Pharmacology (12.3)]. LEROCHOL has not been studied in patients with severe hepatic impairment.

11 Description

Lerodalcibep-liga is a recombinant fusion protein therapeutic agent comprised of a proprotein convertase subtilisin/kexin type 9 (PCSK9)-binding domain and human serum albumin (HSA). Lerodalcibep-liga is produced in genetically engineered mammalian (Chinese hamster ovary) cells as a single protein with an approximate molecular weight of 77 kDa.

LEROCHOL (lerodalcibep-liga) injection is a clear to slightly opalescent, brownish-yellow to amber, sterile, preservative-free solution for subcutaneous injection. Each single-dose prefilled syringe contains 1.2 mL of lerodalcibep-liga (300 mg), histidine (3.07 mg), L-histidine monohydrochloride (0.88), polysorbate 80 (0.24 mg), sodium chloride (10.52), and Water for Injection. The pH is 6.8.

12.1 Mechanism Of Action

Lerodalcibep-liga is a recombinant fusion protein that binds PCSK9 with picomolar affinity. PCSK9 binds to low-density lipoprotein receptor (LDLR) on the surface of hepatocytes to promote LDLR degradation within the liver. By inhibiting the binding of PCSK9 to LDLR, lerodalcibep-liga increases the number of LDLRs available to clear LDL-C from the blood, thereby lowering LDL-C levels. [see Clinical Pharmacology (12.3)].

12.2 Pharmacodynamics

After subcutaneous administration of 300 mg lerodalcibep-liga every month, greater than 90% suppression of PCSK9 occurs within 24 hours after dosing and is maintained throughout the dosing interval, returning toward baseline during the last 7 to 10 days of the monthly dosing period.

12.3 Pharmacokinetics

Following a single subcutaneous administration, exposure to lerodalcibep-liga increased in a dose proportional manner over the dose range 75 to 300 mg of lerodalcibep-liga.

Lerodalcibep-liga pharmacokinetics were observed at steady state in patients at the approved recommended dosage and are presented as mean (SD), unless otherwise specified. Lerodalcibep-liga maximum concentration (Cmax) is 31.4 (10.2) mcg/mL, and total systemic exposure (AUC0-tau) is 12,600 (5,190) (hrs*mcg/mL) following subcutaneous dose of lerodalcibep-liga 300 mg once every four weeks. Lerodalcibep-liga steady-state is reached following 2 to 3 doses. Lerodalcibep-liga accumulation is approximately 30% at the approved recommended dosage.

12.6 Immunogenicity

The observed incidence of anti-drug antibodies (ADA) is highly dependent on the sensitivity and specificity of the assay. Differences in assay methods preclude meaningful comparisons of the incidence of ADA in the studies described below with the incidence of ADA in other studies, including those of lerodalcibep-liga or of other lerodalcibep products.

During the 52-week treatment period in Trial 1 and Trial 2, 15.1% (180/1,195) of LEROCHOL-treated patients at the recommended dosage with evaluable assessments were ADA positive, of whom 22.8% (41/180) had neutralizing antibodies (NAb). During the 24-week treatment period in Trial 3, 11.3% (36/318) of LEROCHOL-treated patients at the recommended dosage with evaluable assessments were ADA positive, of whom 55.6% (20/36) had NAb [see Clinical Studies (14)].

There was no identified clinically significant effect of ADA and NAb on the pharmacokinetics, pharmacodynamics (free PCSK9), safety, or effectiveness (LDL-C) of LEROCHOL over the treatment period of 52 weeks.

13.1 Carcinogenesis, Mutagenesis, Impairment Of Fertility

Carcinogenicity studies have not been performed with lerodalcibep-liga.

The mutagenic potential of lerodalcibep-liga has not been evaluated; however, proteins are not expected to directly interact with DNA or chromosomes.

Fertility studies were not performed. However, in a chronic 6-month toxicology study in sexually mature cynomolgus monkeys, no adverse lerodalcibep-liga-related effects on surrogate markers of fertility (reproductive organ histopathology, menstrual cycling, or sperm parameters) were observed when lerodalcibep-liga was administered subcutaneously at 30 and 100 mg/kg once weekly. The highest dose tested corresponds to 138-fold the recommended human dose of 300 mg every month based on serum AUC.

14 Clinical Studies

The efficacy of LEROCHOL was evaluated in three randomized, double-blind, placebo-controlled trials that enrolled 2,017 adults with HeFH, clinical ASCVD, or increased risk for ASCVD, who were on a stable low-fat, low-cholesterol diet and maximally tolerated statin therapy and who required additional LDL-C lowering.

Patient Information LEROCHOL^TM(leer-O-call) (lerodalcibep-liga) injection, for subcutaneous use
What is LEROCHOL? LEROCHOL is an injectable prescription medicine used along with diet and exercise to reduce low-density lipoprotein cholesterol (LDL-C) or bad cholesterol in adults with high blood cholesterol levels called hypercholesterolemia including heterozygous familial hypercholesterolemia (HeFH). It is not known if LEROCHOL is safe and effective in children.
What should I tell my healthcare provider before using LEROCHOL? Before you start using LEROCHOL, tell your healthcare provider about all of your medical conditions, including if you: are pregnant or plan to become pregnant. It is not known if LEROCHOL will harm your unborn baby. Tell your healthcare provider if you become pregnant while taking LEROCHOL. are breastfeeding or plan to breastfeed. You and your healthcare provider should decide if you will take LEROCHOL or breastfeed. You should not do both without talking to your healthcare provider first.
Tell your healthcare provider or pharmacist about all the medicines you take, including prescription and over-the-counter medicines, vitamins, and herbal supplements.
How should I use LEROCHOL? See the detailed Instructions for Use that comes with this Patient Information about the right way to prepare and give your LEROCHOL injections. Use LEROCHOL exactly as your healthcare provider tells you to use it. LEROCHOL comes as a single-dose (1 time) prefilled syringe. If your healthcare provider decides that you or a caregiver can give the injections of LEROCHOL, you or your caregiver should receive training on the right way to prepare and give LEROCHOL. Do not try to inject LEROCHOL until you have been shown the right way by your healthcare provider or nurse. LEROCHOL is injected under the skin (subcutaneously) 1 time every month. LEROCHOL can be self-injected in the stomach area, at least 2 inches away from the belly button or upper front of the legs (thighs). LEROCHOL can be injected by a caregiver or healthcare provider in the back of the upper arm. Do not choose an area where the skin is tender, bruised, red, or hard. Do not inject LEROCHOL together with other injectable medicines at the same injection site. Always check the label of your syringe to make sure you have the correct medicine. If you forget to use LEROCHOL or are not able to take the dose on your regular schedule, inject your missed dose as soon as you remember if it has been less than 7 days of the missed dose and continue the original monthly dosage schedule. If it is 7 or more days from the missed dose, inject the dose and start a new monthly schedule using the date LEROCHOL was taken. If you are not sure when to re-start LEROCHOL, ask your healthcare provider or pharmacist. If you use more LEROCHOL than you should, talk to your healthcare provider or pharmacist. Do not stop using LEROCHOL without talking with your healthcare provider. If you stop using LEROCHOL, your cholesterol levels can increase.
What are the possible side effects of LEROCHOL? The common side effects of LEROCHOL include: redness, itching, swelling, pain, bruising or tenderness at the injection site runny or stuffy nose, sore throat (nasopharyngitis) diarrhea nausea swelling in arms, hands, legs, or feet (peripheral edema)
Tell your healthcare provider if you have any side effect that bothers you or that does not go away. Ask your healthcare provider or pharmacist for more information. Call your doctor for medical advice about side effects. You may report side effects to FDA at 1-800- FDA-1088.
How should I store LEROCHOL? Store LEROCHOL in the refrigerator between 36°F to 46°F (2°C to 8°C) in the original carton until ready to use and to protect from light.
