Obrixtamig is an antibody with two arms: one grabs DLL3, a protein on the surface of most neuroendocrine carcinomas, and the other grabs a T cell, pulling the killer cell onto the cancer. It is in a phase 3 trial for neuroendocrine carcinomas outside the lung.
Obrixtamig (BI 764532) is Boehringer Ingelheim's DLL3-directed T-cell engager, a class established by tarlatamab in small-cell lung cancer. DLL3 is expressed on the surface of most small-cell lung cancers and extrapulmonary neuroendocrine carcinomas but almost no normal adult tissue. It is given intravenously with step-up dosing to limit cytokine release syndrome.
The phase 2 DAREON-5 trial reported responses in DLL3-positive small-cell lung cancer and extrapulmonary neuroendocrine carcinoma, and the phase 3 DAREON-NEC-1 trial is testing obrixtamig with carboplatin and etoposide first line in DLL3-positive extrapulmonary neuroendocrine carcinoma, the first phase 3 dedicated to that disease. The extrapulmonary neuroendocrine carcinoma page names it with peluntamig and ZG006 among the DLL3 engagers in trials.
