关键词: amivantamab lazertinib EGFR-mutated NSCLC post-osimertinib

摘要:
Amivantamab plus carboplatin-pemetrexed (chemotherapy) with and without lazertinib demonstrated antitumor activity in patients with refractory EGFR-mutated advanced non-small cell lung cancer (NSCLC) in phase 1 studies. These combinations were evaluated in a global phase 3 trial.A total of 657 patients with EGFR-mutated (exon 19 deletions or L858R) locally advanced or metastatic NSCLC after disease progression on osimertinib were randomized 2:2:1 to receive amivantamab-lazertinib-chemotherapy, chemotherapy, or amivantamab-chemotherapy. The dual primary endpoints were progression-free survival of amivantamab-chemotherapy and amivantamab-lazertinib-chemotherapy versus chemotherapy. During the study, hematologic toxicities observed in the amivantamab-lazertinib-chemotherapy arm necessitated a regimen change to start lazertinib after carboplatin completion.All baseline characteristics were well balanced across the 3 arms, including by history of brain metastases and prior brain radiation. Progression-free survival was significantly longer for amivantamab-chemotherapy and amivantamab-lazertinib-chemotherapy versus chemotherapy (hazard ratio for disease progression or death [HR], 0.48 and 0.44, respectively; P<0.001 for both; median of 6.3 and 8.3 versus 4.2 months, respectively). Consistent PFS results were seen by investigator assessment (HR, 0.41 and 0.38 for amivantamab-chemotherapy and amivantamab-lazertinib-chemotherapy, respectively; P<0.001 for both; median of 8.2 and 8.3 versus 4.2 months, respectively). Objective response rate was significantly higher for amivantamab-chemotherapy and amivantamab-lazertinib-chemotherapy versus chemotherapy (64% and 63% versus 36%, respectively; P<0.001 for both). Median intracranial progression-free survival was 12.5 and 12.8 versus 8.3 months for amivantamab-chemotherapy and amivantamab-lazertinib-chemotherapy versus chemotherapy (hazard ratio for intracranial disease progression or death, 0.55 and 0.58, respectively). Predominant adverse events in the amivantamab-containing regimens were hematologic, EGFR, and MET-related toxicities. Amivantamab-chemotherapy had lower rates of hematologic adverse events than amivantamab-lazertinib-chemotherapy.Amivantamab-chemotherapy and amivantamab-lazertinib-chemotherapy improved progression-free survival and intracranial progression-free survival versus chemotherapy in a population with limited options after disease progression on osimertinib. Longer follow-up is needed for the modified amivantamab-lazertinib-chemotherapy regimen.Copyright © 2023 The Author(s). Published by Elsevier Ltd.. All rights reserved.
