Brief summary

The purpose of this study is to assess the efficacy of adding lazertinib to amivantamab, carboplatin, and pemetrexed (LACP/ACP-L dosing strategies) and amivantamab, carboplatin and pemetrexed (ACP) 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. The purpose of the extension cohort is to further describe the safety and efficacy for the ACP-L dosing schedule versus ACP with additional data. After completion of the primary analysis, the study may eventually transition to an open-label extension (OLE) or long-term extension (LTE) phase during which participants will have the option to continue their assigned treatment.

Participant flow

Recruitment details

A total of 657 participants were enrolled in the main study. During the study, a separate open-label randomized extension cohort was added. A total of 119 participants were enrolled into the extension cohort. Main study results are alone reported for primary completion date (PCD; 10-July-2023).

Pre-assignment details

At the time of PCD, extension cohort enrollment was still ongoing. As per protocol, extension cohort analysis was not included as part of main study primary analysis. Currently no information other than total count of participants for extension cohort is available and for reporting purpose extension cohort arms (A2 and C2) have been combined in the table. Results of extension cohort will be reported later, upon completion of analysis, at which point arms A2 and C2 details will be reported.

PFS is defined as the time from randomization until the date of objective disease progression or death, whichever came first, as assessed by BICR according to RECIST version 1.1. Progressed disease: Sum of diameters increased by greater than or equal to (\>=)20 percent (%) and \>=5 millimeter (mm) from nadir (including baseline if it was smallest sum).

Population: Full analysis set (FAS) as defined in the protocol included all randomized participants, classified according to their assigned treatment arm regardless of the actual treatment received. The outcomes reported here are for main study participants. For Arm A participants, data were planned to be analyzed as a single arm collectively for the LACP and ACP-L dosing regimens.
