LAZCLUZE

LAZCLUZE is an FDA-registered drug product whose active ingredient is LAZERTINIB. It is labelled by Janssen Biotech, Inc. taken by oral and marketed as a human prescription drug product. Identifiers on file: NDC 57894-080, application NDA219008, label effective 20260505. This page reproduces the FDA-approved label text so you can check what a product is, who makes it and how it is supplied before discussing it with a pharmacist or prescriber.

Across FDA labelling, products containing LAZERTINIB are most often described in connection with: first-line treatment, adult patients, locally advanced, metastatic non-small, cell lung, cancer nsclc, epidermal growth, factor receptor. Wording differs between labels, and the full indications section on this page takes precedence when it is present.

1 INDICATIONS AND USAGE LAZCLUZE, in combination with amivantamab, is indicated for the first-line treatment of adult patients with locally advanced or metastatic non-small cell lung cancer (NSCLC) with epidermal growth factor receptor (EGFR) exon 19 deletions or exon 21 L858R substitution mutations, as detected by an FDA-approved test [see Dosage and Administration (2.1) ] . LAZCLUZE is a kinase inhibitor indicated in combination with amivantamab for the first-line treatment of adult patients with locally advanced or metastatic non-small cell lung cancer (NSCLC) with epidermal growth factor receptor (EGFR) exon 19 deletions or exon 21 L858R substitution mutations, as detected by an FDA-approved test.

2 DOSAGE AND ADMINISTRATION The recommended dosage of LAZCLUZE is 240 mg orally once daily with or without food, given in combination with amivantamab. ( 2.2 ) Continue treatment until disease progression or unacceptable toxicity. ( 2.2 ) Administer LAZCLUZE any time prior to amivantamab when given on the same day. ( 2.2 ) Refer to the amivantamab prescribing information for recommended amivantamab dosing information. ( 2.2 ) Administer prophylactic and concomitant medications to reduce the risk of dermatologic adverse reactions. ( 2.3 ) Administer anticoagulant prophylaxis to reduce the risk of venous thromboembolic events (VTE) for the first four months of treatment. ( 2.3 ) 2.1 Patient Selection Select patients for the first-line treatment of NSCLC with LAZCLUZE, in combination with amivantamab, based on the presence of EGFR exon 19 deletions or exon 21 L858R substitution mutations in tumor or plasma specimens [see Clinical Studies (14) ] . If these mutations are not detected in a plasma specimen, test tumor tissue. Information on FDA-approved tests is available at: http://www.fda.gov/CompanionDiagnostics . 2.2 Recommended Dosage and Administration Recommended Dosage and Administration The recommended dosage of LAZCLUZE is 240 mg orally once daily administered in combination with amivantamab, with or without food. Swallow LAZCLUZE tablets whole. Do not crush, split, or chew. Continue treatment until disease progression or unacceptable toxicity. Administer LAZCLUZE any time prior to amivantamab when given on the same day. Refer to the amivantamab prescribing information for recommended amivantamab dosing information. Missed Dose If a patient misses a dose of LAZCLUZE within 12 hours, instruct patients to take the missed dose. If more than 12 hours has passed since the dose was to be given, instruct the patient to take the next dose at its scheduled time. Vomiting If vomiting occurs any time after taking LAZCLUZE, instruct the patient to take the next dose at its next regularly scheduled time. 2.3 Prophylactic and Concomitant Medications Venous Thromboembolic Events When initiating treatment with LAZCLUZE in combination with amivantamab, administer anticoagulant prophylaxis to reduce the risk of venous thromboembolic events (VTE) for the first four months of treatment [see Warnings and Precautions (5.1) ]. If there are no signs or symptoms of VTE during the first four months of treatment, consider discontinuation of anticoagulant prophylaxis at the discretion of the healthcare provider. Dermatologic Adverse Reactions When initiating treatment with LAZCLUZE in combination with amivantamab, prophylactic and concomitant medications are recommended to reduce the risk and severity of dermatologic adverse reactions [see Warnings and Precautions (5.3) ] . Administer an oral antibiotic (doxycycline or minocycline, 100 mg orally twice daily) starting on Day 1 for the first 12 weeks of treatment. After completion of oral antibiotic treatment, administer antibiotic lotion to the scalp (clindamycin 1% topical once daily) for the next 9 months of treatment. Administer non-comedogenic skin moisturizer (ceramide-based or other formulations that provide long-lasting skin hydration and exclude drying agents) on the face and whole body (except scalp). Wash hands and feet with 4% chlorhexidine solution once daily. Limit sun exposure during and for 2 months after treatment. Advise patients to wear protective clothing and use broad-spectrum UVA/UVB sunscreen to reduce the risk of dermatologic adverse reactions. 2.4 Dosage Modifications for Adverse Reactions The recommended LAZCLUZE dose reductions for adverse reactions are presented in Table 1. Table 1: Recommended Dose Reductions for Adverse Reactions for LAZCLUZE Dose at which the adverse reaction occurred 1 st Dose Reduction 2 nd Dose Reduction 3 rd Dose Reduction 240 mg once daily (one 240 mg tablet) 160 mg once daily (two 80 mg tablets) 80 mg once daily (one 80 mg tablet) Discontinue LAZCLUZE The recommended management and dosage modifications of LAZCLUZE for specific adverse reactions are presented in Table 2.

Dermatologic Adverse Reactions (including dermatitis acneiform, pruritus, dry skin) [see Warnings and Precautions (5.3) ] Grade 1 Initiate supportive care management as clinically indicated. Grade 2 Initiate supportive care management as clinically indicated. If there is no improvement after 2 weeks, reduce amivantamab dose and continue LAZCLUZE at the same dose. Reassess every 2 weeks, if no improvement, reduce LAZCLUZE dose until ≤ Grade 1 (Table 1), then may resume previous dose of LAZCLUZE at the discretion of the healthcare provider. Grade 3 Withhold LAZCLUZE and amivantamab. Initiate supportive care management as clinically indicated. Upon recovery to ≤ Grade 2, resume LAZCLUZE at the same dose or consider dose reduction, resume amivantamab at a reduced dose. If there is no improvement within 2 weeks, permanently discontinue both LAZCLUZE and amivantamab. Grade 4 (including severe bullous, blistering or exfoliating skin conditions) Initiate supportive care management as clinically indicated. Permanently discontinue amivantamab.

Hepatotoxicity [see Warnings and Precautions (5.4) ] Grade 3–4 Withhold LAZCLUZE and amivantamab until the adverse reaction resolves to ≤ Grade 1 or baseline. Resume both drugs at a reduced dose or LAZCLUZE alone. Consider permanently discontinuing LAZCLUZE and amivantamab if recovery does not occur within 4 weeks. Other Adverse Reactions [see Adverse Reactions (6.1) ] Grade 3–4 Withhold LAZCLUZE and amivantamab until the adverse reaction resolves to ≤ Grade 1 or baseline. Resume both drugs at a reduced dose or LAZCLUZE alone. Consider permanently discontinuing both LAZCLUZE and amivantamab if recovery does not occur within 4 weeks.

Adverse reactions which resulted in permanent discontinuation of LAZCLUZE in ≥ 1% of patients included ILD/pneumonitis, pneumonia, VTE, rash, respiratory failure, and sudden death. Dosage interruption of LAZCLUZE due to an adverse reaction occurred in 72% of patients. Adverse reactions which required dosage interruption in ≥ 5% of patients were rash, nail toxicity, COVID-19, VTE, increased ALT, and increased AST. Dose reductions of LAZCLUZE due to an adverse reaction occurred in 42% of patients. Adverse reactions requiring LAZCLUZE dose reductions in ≥ 5% of patients were rash and nail toxicity.
