Obrixtamig (BI 764532; OBT 620) is an CD3E/DLL3 -targeting L-κ-G1-h-CH2-CH3_L-λ-G1-h-CH2-CH3 type human antibody. Obrixtamig is a delta-like ligand 3 (DLL3)/CD3 IgG-like T-cell engager. Obrixtamig can be used for research of DLL3-positive small cell lung cancer [1].
In Vitro, Obrixtamig has entered the first phase of clinical trials and is being used for the researches of DLL3-positive small cell lung cancer (SCLC), extrapulmonary neuroendocrine carcinomas (epNECs), or large cell neuroendocrine carcinoma of the lung (LCNEC-L)[1].
