Abstract
- Background Although osimertinib, a third-generation EGFR tyrosine kinase inhibitor (TKI) is approved for first-line (1L) treatment of EGFR -mutated metastatic non-small cell lung cancer (NSCLC) and second-line (2L) treatment of pts who acquired the EGFR T790M mutation during 1L therapy with other TKIs, treatment options after progression on TKIs are limited; platinum-doublet chemotherapy (PT-DC) remains the standard therapy, including for pts with no T790M mutation. Nivolumab (NIVO), a fully human IgG4 programmed death-1 immune checkpoint inhibitor antibody, is approved worldwide for the treatment of advanced NSCLC on or after prior chemotherapy. CheckMate 722 (NCT02864251) will compare the efficacy and safety of NIVO + PT-DC vs PT-DC alone in pts with EGFR -mutated metastatic or recurrent NSCLC progressed on 1L or 2L EGFR TKI therapy. Methods This open-label phase 3 trial is enrolling ∼500 adults with confirmed stage IV or recurrent EGFR -mutated NSCLC progressed on prior EGFR TKI therapy. Patients are eligible if they progressed on 1L first- or second-generation TKIs with no T790M mutation or 1L or 2L osimertinib regardless of T790M status. Pts with CNS metastases that are adequately controlled and/or treated during screening are eligible. Pts are randomized 1:1 to NIVO (360 mg Q3W) + PT-DC (pemetrexed 500 mg/m2 Q3W + cisplatin 75 mg/m2 or carboplatin AUC 5 or 6 Q3W), or PT-DC alone; pts without disease progression after 4 cycles will receive NIVO + pemetrexed or pemetrexed, respectively, until disease progression or unacceptable toxicity. Randomization is stratified by programmed death ligand-1 status (≥ 1% or < 1%/not evaluable), presence or absence of brain metastases, smoking history and prior osimertinib treatment. The primary endpoint is progression-free survival (PFS). Secondary endpoints include overall survival, objective response rate, duration of response, and PFS rates at 9 and 12 months. Results The estimated primary completion date is September 2019. [ABSTRACT FROM AUTHOR]
