A Study of Amivantamab and Lazertinib in Combination With Platinum-Based Chemotherapy Compared With Platinum-Based Chemotherapy in Patients With Epidermal Growth Factor Receptor (EGFR)-Mutated Locally Advanced or Metastatic Non- Small Cell Lung Cancer After Osimertinib Failure

Official Title

A Phase 3, Open-Label, Randomized Study of Amivantamab and Lazertinib in Combination With Platinum-Based Chemotherapy Compared With Platinum-Based Chemotherapy in Patients With EGFR-Mutated Locally Advanced or Metastatic Non-Small Cell Lung Cancer After Osimertinib Failure

Summary:

The purpose of this study is to assess the efficacy of lazertinib, amivantamab, carboplatin, and pemetrexed (LACP) compared with carboplatin and pemetrexed (CP), in participants with locally advanced or metastatic epidermal growth factor receptor (EGFR) Exon 19del or Exon 21 L858R substitution non-small cell lung cancer (NSCLC) after osimertinib failure.

Lung cancer is one of the most common types of cancer and is the most common cause of death from cancer. NSCLC accounts for approximately 85 percent (%) of lung cancers. Advanced NSCLC is a serious terminal illness that accounts for approximately 20% of all cancer mortality, and until recently had a median overall survival (OS) of approximately 1 year. Amivantamab (JNJ-61186372) is a low fucose, fully human immunoglobulin (IgG)1-based bispecific antibody directed against EGFR and mesenchymal-epithelial transition (MET) tyrosine kinase receptors. It shows clinical activity against tumours with primary activating EGFR mutations Exon 19del and Exon 21 L858R substitution. Lazertinib (JNJ-73841937; YH-25448) is an oral, highly potent, third-generation EGFR tyrosine kinase inhibitor (TKI). It selectively inhibits both primary activating EGFR mutations (Exon 19del, Exon 21 L858R substitution) and the EGFR T790M resistance mutation, with less inhibition of wild-type EGFR. The study consists of a Screening Phase (up to 28 days), a Treatment Phase (from randomization until the End of Treatment visit) and a Follow-up Phase (from End of Treatment Visit until the end of study, death, lost to follow-up, or withdrawal of consent, whichever comes first). Safety will be assessed by physical examinations, laboratory tests, vital signs, electrocardiograms, Eastern Cooperative Oncology Group (ECOG) performance status, and monitoring of adverse events (AEs). The total duration of the study is up to 48 months.
