J INTS BIO to Present Global Clinical Results from JIN-A02, a Fourth-Generation EGFR-TKI, at ASCO 2025
On June 1, 2025, in Seoul, Korea, J INTS BIO revealed preliminary findings from their worldwide Phase 1/2 clinical study of JIN-A02, a fourth-generation EGFR-TKI, with a presentation scheduled at ASCO 2025 in Chicago.
The trial addresses resistance mutations like C797S, which emerge after failure of third-generation EGFR-TKIs, the current first-line treatment for EGFR-mutant NSCLC.
Key findings showed confirmed partial responses across 50mg, 100mg, and 300mg doses, with a 77.3% tumor reduction at 50mg sustained over six cycles and notable brain metastases reduction at higher doses.
JIN-A02 exhibited no dose-limiting toxicities up to 300mg, with mostly mild adverse events common to EGFR inhibitors, supporting an excellent safety profile and prolonged patient treatment durations.
J INTS BIO earned selection for the government’s '2025 Baby Unicorn Fostering Project', securing dual funding to accelerate Phase 2 trials and global expansion over two years alongside private investment.
