Oral dosing of ATG-008, 10mg/kg, QD, induced potent tumor growth inhibition(TGI) in MUC5B mutant CDX models, with 53.2% TGI in NCI-H82 model and 81.9% TGI in SK-MES-1 model. However, in MUC5B wild type models, the TGI is only 20.5% in NCI-H209 model and 36% in NCI-H526.These results suggest that the presence of MUC5B mutation correlates with more potent anti-tumor efficacy of ATG-008, potentially serving as a positive predictive biomarker for patient...
