DB-1418, a bispecific antibody-drug conjugate (ADC) targeting EGFR and HER3, demonstrates superior and broad antitumor efficacy and favorable safety in preclinical models (AACR 2025) - "Notably, in an osimertinib-resistant NSCLC xenograft model with the C797S mutation, DB-1418 induced tumor regression with a TGI of 98% at a dose of 6 mg/kg Q3W, significantly higher than the BL-B01D1 analog at 6 mg/kg Q3W (TGI of 68%, p<0.01). DB-1418 has shown promising pharmacological and pharmacokinetic properties, differentiated from the current clinical trial bispecific ADC targeting EGFR and HER3, with a broader therapeutic window. DB-1418 offers additional treatment options for patients who have developed resistance to EGFR tyrosine kinase inhibitors (TKIs) and addresses other unmet medical needs."
