Abstract 398TiP
Background
Epidermal growth factor receptor (EGFR) tyrosine kinase inhibitors (TKIs) effectively treat patients with non-small cell lung cancer (NSCLC) with EGFR-sensitizing mutations; however, almost all will eventually relapse due to new mutations on or after osimertinib the 3rd generation TKI. The current standard of care is platinum doublet chemotherapy after progression on osimertinib, but with limited benefit. Amivantamab, an EGFR and MET bispecific humanized antibody, has shown clinical activity against tumors with primary activating EGFR mutations, EGFR resistance mutations, or MET pathway activation. Lazertinib is an oral, brain-penetrant, 3rd generation EGFR TKI. Amivantamab and lazertinib in combination has demonstrated clinically significant activity in post-osimertinib disease. Amivantamab and lazertinib in combination with platinum-based chemotherapy after osimertinib failure would provide improved clinical benefits compared to chemotherapy alone.
Trial design
MARIPOSA-2, a randomized, open-label, Phase 3 study, will evaluate the efficacy and safety of lazertinib, amivantamab, carboplatin, and pemetrexed (“LACP”; Arm A) vs carboplatin and pemetrexed (“CP”; Arm B) in participants with EGFR-mutated locally advanced or metastatic nonsquamous NSCLC following progression on or after osimertinib. A third treatment group will receive amivantamab, carboplatin, and pemetrexed (“ACP”; Arm C) to assess the contribution of lazertinib in the LACP. There will be 500 eligible participants randomly assigned 2:2:1 (Arms A:B:C) and stratified by osimertinib line of therapy (1st vs 2nd-line), brain metastases, and Asian race. Efficacy will be assessed by blinded independent central review (RECIST v1.1); the primary endpoint will be progression-free survival; key secondary endpoints include objective response rate, overall survival, safety, and health-related quality of life.
