Uses
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.

Dosage
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.
Side Effects
6 ADVERSE REACTIONS The following adverse reactions are discussed elsewhere in the labeling: Venous Thromboembolic Events [see Warnings and Precautions (5.1) ] Interstitial Lung Disease/Pneumonitis [see Warnings and Precautions (5.2) ] Dermatologic Adverse Reactions [see Warnings and Precautions (5.3) ] Ocular Toxicity [see Warnings and Precautions (5.4) ] LAZCLUZE in Combination with Amivantamab The most common adverse reactions (≥ 20%) were rash, nail toxicity, infusion-related reaction (amivantamab), musculoskeletal pain, edema, stomatitis, VTE, paresthesia, fatigue, diarrhea, constipation, COVID-19, hemorrhage, dry skin, decreased appetite, pruritus, and nausea.
Interactions
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.
Warnings
5 WARNINGS AND PRECAUTIONS Venous Thromboembolic Events (VTE): Prophylactic anticoagulation is recommended for the first four months of treatment. Monitor for signs and symptoms of VTE and treat as medically appropriate. Withhold LAZCLUZE and amivantamab based on severity. Once anticoagulant treatment has been initiated, resume LAZCLUZE and amivantamab at the same dose at the discretion of the healthcare provider. Permanently discontinue amivantamab and continue LAZCLUZE for recurrent VTE despite therapeutic anticoagulation. ( 2.3 , 2.4 , 5.1 ) Interstitial Lung Disease (ILD)/Pneumonitis : Monitor for new or worsening symptoms indicative of ILD/pneumonitis. 4 CONTRAINDICATIONS None. None. ( 4 )
Pregnancy
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.
Storage
