7 Drug Interactions

Strong and moderate CYP3A4 inducers:Avoid concomitant use. ( 7.1)

7.1 Effect of Other Drugs on LAZCLUZE

CYP3A4 Inducers

Avoid concomitant use of LAZCLUZE with strong and moderate CYP3A4 inducers. Consider an alternate concomitant medication with no potential to induce CYP3A4.

Lazertinib is a CYP3A4 substrate. Concomitant use with a strong or moderate CYP3A4 inducer decreased lazertinib concentrations [see Clinical Pharmacology (12.3)] , which may reduce the efficacy of lazertinib.

7.2 Effect of LAZCLUZE on Other Drugs

Certain CYP3A4 Substrates

Monitor for adverse reactions associated with a CYP3A4 substrate where minimal concentration changes may lead to serious adverse reactions, as recommended in the approved product labeling for the CYP3A4 substrate.

Lazertinib is a weak CYP3A4 inhibitor. Concomitant use of LAZCLUZE increased concentrations of CYP3A4 substrates [see Clinical Pharmacology (12.3)] , which may increase the risk of adverse reactions related to these substrates.

Certain BCRP Substrates

Monitor for adverse reactions associated with a BCRP substrate where minimal concentration changes may lead to serious adverse reactions, as recommended in the approved product labeling for the BCRP substrate.

Lazertinib is a BCRP inhibitor. Concomitant use of LAZCLUZE increased concentrations of BCRP substrates [see Clinical Pharmacology (12.3)], which may increase the risk of adverse reactions related to these substrates.

8 Use In Specific Populations

Lactation:Advise not to breastfeed. ( 8.2)

8.1 Pregnancy

Risk Summary

Based on findings from animal studies and its mechanism of action [see Clinical Pharmacology (12.1)] , LAZCLUZE can cause fetal harm when administered to a pregnant woman. There are no available data on the use of LAZCLUZE in pregnant women to inform a drug-associated risk. Oral administration of lazertinib to pregnant animals during the period of organogenesis resulted in reduced embryo-fetal survival and fetal body weight in rats and malformations in rabbits at exposures approximately 4 and 0.5 times, respectively, the human exposure at the recommended dose of 240 mg/day based on AUC (see Data) . Advise pregnant women of the potential risk to a fetus.

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 an embryo-fetal development study, pregnant rats received oral doses of 7.5, 30, or 60 mg/kg/day of lazertinib during the period of organogenesis (gestation day 6 to 17). Lazertinib decreased fetal body weights in association with maternal toxicity at 60 mg/kg/day (approximately 4 times the human exposure at the recommended dose of 240 mg/day based on AUC). In a dose range-finding embryo-fetal development study, oral administration of a higher dose of lazertinib (75 mg/kg/day) to pregnant rats during the period of organogenesis resulted in increased post-implantation loss. In an embryo-fetal development study in rabbits, pregnant animals received oral doses of 5, 25, or 45 mg/kg/day of lazertinib during the period of organogenesis (gestation day 7 to 19). Lazertinib caused maternal toxicity (reduced body weight and food consumption leading to moribund condition and early termination) and an increase in the incidence of skeletal malformations in the vertebra and skull (fused maxillary process/zygomatic arch) at 45 mg/kg/day (approximately 0.5 times the human exposure at the recommended dose of 240 mg/day based on AUC).

8.2 Lactation

Risk Summary

There are no data on the presence of lazertinib or its metabolites in human milk or their effects on the breastfed child or on milk production. Because of the potential for serious adverse reactions in breastfed children, advise women not to breastfeed during treatment with LAZCLUZE and for 3 weeks after the last dose. Refer to the amivantamab prescribing information for lactation information during treatment with amivantamab.

8.3 Females and Males of Reproductive Potential

Based on animal data and its mechanism of action, LAZCLUZE can cause fetal harm when administered to a pregnant woman [see Use in Specific Populations (8.1)] .

Pregnancy Testing

Verify the pregnancy status of females of reproductive potential prior to initiating LAZCLUZE.

Contraception

Females

Advise females of reproductive potential to use effective contraception during treatment with LAZCLUZE and for 3 weeks after the last dose. Refer to the amivantamab prescribing information for recommended duration of contraception during treatment with amivantamab.

Males

Advise male patients with female partners of reproductive potential to use effective contraception during treatment with LAZCLUZE and for 3 weeks after the last dose.

Infertility

Based on findings in animals, LAZCLUZE may impair fertility in females and males of reproductive potential. The effects on female fertility were reversible. The effects on male testes in animal studies were not reversible within a 2-week recovery period [see Nonclinical Toxicology (13.1)].

8.4 Pediatric Use

The safety and effectiveness of LAZCLUZE in pediatric patients have not been established.

8.5 Geriatric Use

Of the 421 patients with locally advanced or metastatic NSCLC treated with LAZCLUZE in combination with amivantamab in MARIPOSA, 45% were 65 years and older and 12% were 75 years and older. No overall differences in safety or effectiveness were observed between patients aged 65 and older and younger patients.

11 Description

LAZCLUZE™ tablets contain lazertinib, a kinase inhibitor for oral use. Lazertinib is present as lazertinib mesylate hydrate with a molecular weight of 668.77 and molecular formula of C ₃₀H ₃₄N ₈O ₃∙CH ₄O ₃S∙H ₂O. The chemical name is N-[5-[[4-[4-[(Dimethylamino)methyl]-3-phenyl-1 H-pyrazol-1-yl]pyrimidin-2-yl]amino]-4-methoxy-2-(morpholin-4-yl)phenyl]acrylamide methanesulfonate hydrate (1:1:1). Lazertinib mesylate hydrate is soluble or practically insoluble in aqueous media, and slightly soluble to freely soluble in organic solvents over a wide range of pH values. The structural formula is:

LAZCLUZE (lazertinib) film-coated tablets contain 80 mg or 240 mg of lazertinib, equivalent to 93.86 and 281.58 mg lazertinib mesylate (calculated on anhydrous basis), respectively. The inactive ingredients are croscarmellose sodium, magnesium stearate, mannitol, microcrystalline cellulose, and silica hydrophobic colloidal. The tablet coating consists of glycerol monocaprylocaprate type I, iron oxide black (in 240 mg strength tablets), iron oxide red (in 240 mg strength tablets), iron oxide yellow (in 80 mg strength tablets), macrogol (PEG) polyvinyl alcohol graft copolymer, polyvinyl alcohol- partially hydrolyzed, talc, and titanium dioxide.

12 Clinical Pharmacology

12.1 Mechanism of Action

Lazertinib is a kinase inhibitor of epidermal growth factor receptor (EGFR) that inhibits EGFR exon 19 deletions and exon 21 L858R substitution mutations at lower concentrations than wild-type EGFR. In human NSCLC cells and mouse xenograft models of EGFR exon 19 deletions or EGFR L858R substitution mutations, lazertinib demonstrated anti-tumor activity. Treatment with lazertinib in combination with amivantamab increased in vivo anti-tumor activity compared to either agent alone in a mouse xenograft model of human NSCLC with an EGFR L858R mutation.

12.2 Pharmacodynamics

The exposure-response relationship and time-course of pharmacodynamic response of lazertinib have not been fully characterized.

Cardiac Electrophysiology

At a dose of 320 mg (1.3 times the approved recommended dosage) once daily, a mean increase in the QTc interval > 20 ms is unlikely.

12.3 Pharmacokinetics

Lazertinib pharmacokinetics are presented as mean (CV%) for descriptive parameters unless otherwise specified.

Lazertinib maximum plasma concentration (C _max) and area under plasma concentration time curve (AUC) increased dose proportionally from 20 mg to 320 mg (0.08 to 1.3 times the approved recommended dosage) following a single administration and once daily administration. Lazertinib steady state plasma exposure was achieved by day 15 with approximately 2-fold accumulation for AUC.

Absorption

The median time to reach C _maxis from 2 to 4 hours.

Effect of Food

A high-fat meal (800 to 1000 kcal, approximately 50% fat) did not have a clinically significant effect on lazertinib pharmacokinetics compared to that under fasted conditions.

Distribution

The mean apparent volume of distribution is 2680 L (51%).

Lazertinib is approximately 99.2% bound to human plasma proteins.

Elimination

The mean terminal half-life is 3.7 days (56%).

The mean apparent clearance is 36.4 L/h (47%).

Metabolism

Lazertinib is primarily metabolized by glutathione conjugation, either enzymatic via glutathione-S-transferase (GST) or non-enzymatic, as well as by CYP3A4.

Excretion

Following a single oral dose of radiolabeled lazertinib, approximately 86% of the dose was recovered in feces (< 5% as unchanged) and 4% in urine (< 0.2% as unchanged).

Specific Populations

No clinically significant differences in pharmacokinetics of lazertinib were observed based on age (21 to 88 years), sex, body weight (28 to 122 kg), race (White, Asian, Black or African American), ethnicity (Hispanic/Latino or not Hispanic/Latino), baseline laboratory assessments (creatinine clearance, albumin, alanine aminotransferase, alkaline phosphatase, aspartate aminotransferase), mild or moderate renal impairment (eGFR 30 to 89 mL/min, estimated by CKD-EPI equation), mild [total bilirubin ≤ ULN and AST > ULN or total bilirubin ≤ 1.5 times ULN and any AST] or moderate [total bilirubin ≤ 1.5 to 3×ULN and any AST] hepatic impairment, ECOG performance status, EGFR mutation type, initial diagnosis cancer stage, prior therapies, brain metastasis, and history of smoking.

The effect of severe renal impairment (eGFR 15 to 29 mL/min), end-stage renal disease (eGFR < 15 mL/min) or severe hepatic impairment (total bilirubin > 3 times ULN with any AST) on the pharmacokinetics of lazertinib has not been studied.

GSTM1 Genotype

Patients with at least one GSTM1 normal function allele have 44% lower systemic levels of lazertinib compared with those with the two GSTM1 no-function alleles (i.e., no enzyme activity). No clinically significant differences in safety or efficacy were observed as a function of GSTM1 genotype in patients receiving LAZCLUZE in combination with amivantamab.

Drug Interactions

Clinical Studies and Model-Informed Approaches

Effect of CYP3A4 inducers on lazertinib:

Concomitant use of rifampin (strong CYP3A4 inducer) with LAZCLUZE decreased lazertinib C _maxby 72% and AUC by 83%.

Concomitant use of efavirenz (moderate CYP3A4 inducer) with LAZCLUZE is predicted to decrease lazertinib steady state C _maxby at least 32% and AUC by at least 44%.

The effect of concomitant use of weak CYP3A4 inducers on lazertinib C _maxor AUC is unknown.

Effect of strong CYP3A4 inhibitors on lazertinib:

Concomitant use of itraconazole (strong CYP3A4 inhibitor) with LAZCLUZE increased lazertinib C _maxby 1.2-fold and AUC by 1.5-fold.

Effect of gastric acid reducing agents on lazertinib:

No clinically significant differences in lazertinib C _maxand AUC were observed when used concomitantly with gastric acid reducing agents.

Effect of lazertinib on certain CYP3A4 substrates:

Concomitant use of LAZCLUZE increased midazolam (CYP3A4 substrate) C _maxby 1.4-fold and AUC by 1.5-fold.

Effect of lazertinib on BCRP substrates:

Concomitant use of LAZCLUZE increased rosuvastatin (BCRP substrate) C _maxby 2.2-fold and AUC by 2-fold.

No clinically significant differences in the pharmacokinetics of the following were observed or predicted when used concomitantly with lazertinib: metformin (OCT1 substrate) or raltegravir (UGT1A1 substrate).

In Vitro Studies

Lazertinib inhibits CYP3A4, UGT1A1, BCRP and OCT1. Lazertinib does not induce CYP1A2, CYP2B6 and CYP3A4.

13 Nonclinical Toxicology

13.1 Carcinogenesis, Mutagenesis, Impairment of Fertility

Carcinogenicity studies have not been conducted with lazertinib.

Lazertinib was not genotoxic in an in vitro bacterial reverse mutation (Ames) assay, an in vitro chromosomal aberration assay, or an in vivo micronucleus assay in rats.

In a dedicated fertility and early embryonic development study, male and female rats received oral doses of 7.5, 15, or 30 mg/kg/day of lazertinib. Males were dosed for 10 weeks (29 days prior to pairing, during mating period and continuing post-pairing). Females were dosed for 15 days prior to pairing, during mating period and up to Gestation Day 7. Lazertinib did not have clear effects on estrous cyclicity, mating, fertility, or sperm parameters, but induced an increase in post-implantation loss and decreased number of live fetuses at 30 mg/kg/day (approximately 1.2 times the recommended human dose of 240 mg based on body surface area). In repeat-dose oral general toxicology studies up to 13-weeks duration, lazertinib induced histologic tubular degeneration in the testis; cellular lumen debris, degeneration/necrosis, and reduced sperm in the epididymis; decreased corpora lutea in the ovary; and atrophy in the uterus and vagina. These effects were observed at exposures approximately equivalent to the human exposure at the recommended dose of 240 mg in males, and at exposures approximately 2 times the human exposure at the recommended dose of 240 mg dose in females. Findings in female reproductive organs were reversible. The tubular degeneration in the testis observed in rats at exposures approximately 4 times the human exposure at the recommended dose was not reversible within a 2-week recovery period.

13.2 Animal Toxicology and/or Pharmacology

In repeat-dose oral general toxicology studies up to 13-weeks duration in rats and dogs, lazertinib induced multi-organ histologic hyperplasia at exposures approximately equivalent or greater to the human exposure at the recommended dose of 240 mg. Hyperplasia was not reversible in the mandibular lymph node in the 4-week rat study. In rats, lazertinib induced renal toxicity characterized by histologic hyperplasia and inflammation in the kidney at doses ≥ 25 mg/kg (approximately 0.9 times the human exposure at the recommended dose of 240 mg/day based on AUC), along with increased urea nitrogen and histologic papillary necrosis, tubule degeneration/regeneration, and tubule dilatation at exposures approximately 4.4 times the human exposure at the recommended dose of 240 mg/day based on AUC. Increased urea nitrogen, papillary necrosis, and tubule dilatation showed evidence of recovery. In the 13-week toxicology study in dogs, one high dose animal exhibited unilateral tubule cell renal carcinoma at 8 mg/kg/day (approximately 2 times the human exposure at the recommended dose of 240 mg/day based on AUC). Other renal findings in high dose dogs included tubule degeneration/regeneration and infarct, which showed evidence of recovery. In the 4-week toxicology study, lazertinib induced cardiac toxicity in two dogs characterized by histologic findings in the heart (degeneration/necrosis of the myocardium and vessels, fibrosis, hemorrhage, thrombus, mixed cell/vessel inflammation) at 20 mg/kg (approximately 4.8 times the clinical AUC at the 240 mg human dose). One of these dogs also exhibited increased cardiac troponin I and premature ventricular complexes. These cardiac findings were not seen after a 2-week recovery period.

14 Clinical Studies

The efficacy of LAZCLUZE, in combination with amivantamab, was evaluated in MARIPOSA [NCT04487080], a randomized, active-controlled, multicenter trial. Eligible patients were required to have untreated locally advanced or metastatic NSCLC with either exon 19 deletions or exon 21 L858R substitution EGFR mutations identified by local testing, not amenable to curative therapy. Patients with asymptomatic or previously treated and stable intracranial metastases were eligible to enroll.

Patients were randomized (2:2:1) to receive LAZCLUZE in combination with amivantamab (N=429), osimertinib monotherapy (N=429), or LAZCLUZE monotherapy (an unapproved regimen for NSCLC) until disease progression or unacceptable toxicity. The evaluation of efficacy for the treatment of untreated metastatic NSCLC relied upon comparison between:

LAZCLUZE administered at 240 mg orally once daily in combination with amivantamab administered intravenously at 1050 mg (for patients < 80 kg) or 1400 mg (for patients ≥ 80 kg) once weekly for 4 weeks, then every 2 weeks thereafter starting at week 5.

Osimertinib administered at a dose of 80 mg orally once daily.

Randomization was stratified by EGFR mutation type (exon 19 deletion or exon 21 L858R substitution mutation), Asian race (yes or no), and history of brain metastasis (yes or no). Tumor assessments were performed every 8 weeks for 30 months, and then every 12 weeks until disease progression.

The major efficacy outcome measure was progression-free survival (PFS) as assessed by blinded independent central review (BICR). Additional efficacy outcome measures included overall survival (OS), overall response rate (ORR) and duration of response (DOR).

A total of 858 patients were randomized between the two study arms, 429 to the LAZCLUZE in combination with amivantamab arm and 429 to the osimertinib arm. The median age was 63 (range: 25–88) years; 61% were female; 58% were Asian, and 38% were White, 1.6% were American Indian or Alaska Native, 0.8% were Black or African American, 0.2% were Native Hawaiian or other Pacific Islander, 0.6% were unknown race or multiple races; and 12% were Hispanic or Latino. Eastern Cooperative Oncology Group (ECOG) performance status was 0 (34%) or 1 (66%); 69% never smoked; 41% had prior brain metastases; and 89% had Stage IV cancer at initial diagnosis. Sixty percent of patients had tumors harboring exon 19 deletions and the remaining 40% had exon 21 L858R substitution mutations.

Among the 858 patients with EGFR exon 19 deletion or L858R substitution mutations that were randomized between the amivantamab plus LAZCLUZE arm versus the osimertinib arm, available tissue samples from 544 (63%) patients had evaluable results when tested retrospectively using the cobas EGFR Mutation Test v2. Of the 544 patients with evaluable results, 527 (97%) patients were positive for EGFR exon 19 deletion or L858R substitution mutations, while 17 (3%) patients were negative. Available plasma samples from patients were retrospectively tested using an FDA-approved test to confirm the biomarker status.

The trial demonstrated a statistically significant improvement in PFS by BICR assessment for LAZCLUZE in combination with amivantamab compared to osimertinib.

Efficacy results are provided in Table 5.

PATIENT INFORMATION LAZCLUZE™ (laz-kluez) (lazertinib) tablets, for oral use

This Patient Information has been approved by the U.S. Food and Drug Administration. Revised: 08/2024

What is LAZCLUZE? LAZCLUZE in combination with amivantamab is a prescription medicine for the first-line treatment of adults with non-small cell lung cancer (NSCLC) that:

has spread to other parts of the body (metastatic) or cannot be removed by surgery, and

has a certain abnormal epidermal growth factor receptor "EGFR" gene(s).

Your healthcare provider will perform a test to make sure that LAZCLUZE is right for you. It is not known if LAZCLUZE is safe and effective in children.

Before taking LAZCLUZE, tell your healthcare provider about all of your medical conditions, including if you:

have a history of lung or breathing problems

are pregnant or plan to become pregnant. LAZCLUZE can harm your unborn baby. Females who are able to become pregnant:

Your healthcare provider should do a pregnancy test before you start treatment with LAZCLUZE.

You should use effective birth control (contraception) during treatment and for 3 weeks after your last dose of LAZCLUZE.

Tell your healthcare provider right away if you become pregnant or think you might be pregnant during treatment with LAZCLUZE.

Males who have female partners who are able to become pregnant:

You should use effective birth control during treatment and for 3 weeks after your last dose of LAZCLUZE.

are breastfeeding or plan to breastfeed. It is not known if LAZCLUZE passes into your breast milk. Do not breastfeed during treatment and for 3 weeks after your last dose of LAZCLUZE.

Tell your healthcare provider about all the medicines you take, including prescription and over-the-counter medicines, vitamins, and herbal supplements. LAZCLUZE may affect the way other medicines work, and other medicines may affect how LAZCLUZE works. You should not start or stop any medicine before you talk with your healthcare provider that prescribed LAZCLUZE.

How should I take LAZCLUZE?

Take LAZCLUZE exactly as your healthcare provider tells you to take it.

Take LAZCLUZE 1-time each day. On the day amivantamab is also given, take LAZCLUZE any time before receiving the amivantamab infusion.

You can take LAZCLUZE with or without food.

Swallow LAZCLUZE tablets whole. Do notcrush, cut, or chew the tablets.

If you miss a dose of LAZCLUZE and:

it has been less than12 hours, take the missed dose.

it has been more than12 hours, skip the dose and take your next dose at your regularly scheduled time.

If you vomit a dose of LAZCLUZE, do not take an extra dose. Take your next dose at your regularly scheduled time.

LAZCLUZE may be given in combination with other anti-cancer medicines. If you have any questions about these medicines, ask your healthcare provider.

What should I avoid while taking LAZCLUZE? LAZCLUZE can cause skin reactions. You should limit your time in the sun during and for 2 months after your treatment with LAZCLUZE. Wear protective clothing and use sunscreen during treatment with LAZCLUZE.

What are the possible side effects of LAZCLUZE? LAZCLUZE may cause serious side effects, including:

blood clot problems.Blood clots in the veins of your legs (deep vein thrombosis) or lungs (pulmonary embolism) are serious, but common, and may lead to death. Your healthcare provider will start you on medicine to prevent blood clots for the first four months of treatment. Tell your healthcare provider right away if you have any signs and symptoms of blood clots, including swelling, pain or tenderness in the leg, sudden unexplained chest pain, or shortness of breath.

lung problems.LAZCLUZE may cause lung problems that may lead to death. Symptoms may be similar to those symptoms from lung cancer. Tell your healthcare provider right away if you get any new or worsening lung symptoms, including shortness of breath, cough, or fever.

skin problems.LAZCLUZE may cause severe rash including redness, raised acne-like bumps, itching, and dry skin. You may use alcohol-free (such as isopropanol-free, ethanol-free) moisturizing cream to reduce the risk of skin problems. Limit sun exposure during and for 2 months after treatment with LAZCLUZE. Wear protective clothing and use sunscreen. Tell your healthcare provider right away if you get any skin reactions. Your healthcare provider may recommend that you start a medicine to prevent skin problems, may treat you with a medicine(s), or send you to see a skin speciaul (dermatologist) if you get skin reactions during treatment with LAZCLUZE. See " What should I avoid while taking LAZCLUZE?"

eye problems.LAZCLUZE may cause eye problems such as inflamed cornea (front part of your eye). Tell your healthcare provider right away if you get symptoms such as eye redness, eye pain, new or worsening problems with vision, and sensitivity to light.

Your healthcare provider may send you to see an eye speciaul (ophthalmologist) if you get eye problems during treatment with LAZCLUZE. You should not use contact lenses until your eye symptoms are checked by a healthcare provider. The most common side effects of LAZCLUZE in combination with amivantamab include:

rash

infected skin around the nail

infusion-related reaction (amivantamab)
