Bridge Biotherapeutics announced on the 27th that it had applied to the FDA for a phase 1/2 clinical trial plan for 'BBT-207', a 4th generation non-small cell lung cancer drug candidate. BBT207 is a new drug candidate that targets the C797S mutation that can occur after using third-generation non-small cell lung cancer treatments such as Tagrisso. Bridge Biotherapeutics plans to conduct clinical trials at 15 to 20 institutions in the US and Korea when the phase 1/2 clinical trial plan is approved. This clinical trial is a study to evaluate the safety, pharmacokinetic/pharmacodynamic properties, and efficacy of BBT-207 in patients with advanced non-small cell lung cancer with EGFR mutation after EGFR TKI treatment.
