Abstract 597TiP
Background
EGFR mutations are the most common driver mutations in non-small cell lung cancer (NSCLC). While EGFR tyrosine kinase inhibitors (TKIs) are the recommended front-line treatment for advanced NSCLC patients with EGFR mutations, these patients inevitably develop acquired resistance and face disease progression. JIN-A02, a 4th generation EGFR TKI, selectively and reversibly binds to EGFR mutations, including C797S mutation that results from the use of 3rd generation TKI such as osimertinib. In preclinical studies, JIN-A02 demonstrated activity against both double and triple C797S mutations. This international, open-label, phase 1/2 study is designed to evaluate the safety and efficacy of JIN-A02 in EGFR-mutant NSCLC patients (NCT05394831).
Trial design
This study has three parts; dose escalation (Part A), dose exploration (Part B), and dose expansion (Part C). Part A explores ascending daily doses of oral JIN-A02 monotherapy to evaluate the maximum tolerated dose in patients with advanced NSCLC harboring C797S or T790M mutation. Based on the results in Part A, two doses will be selected to be further evaluated in Part B in the same way with Part A but in a larger cohort of patients. This will determine the recommended phase 2 dose which will be studied in Part C in five cohorts based on the EGFR mutation and brain metastasis status.
