LAZCLUZE

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. Absorpti...

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 monother...

None. None. ( 4 )

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 anticoagulati...

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 ...
