Targeting DLL3 in Neuroendocrine Carcinomas; Establishing Novel Biomarkers in Novel Indications

  • DLL3 is an actionable target, expressed in a number of tumour types, but rarely in healthy tissues
  • Extra-pulmonary neuroendocrine carcinomas (epNEC) are highly aggressive and, to date, do not include any approved targeted therapies as part of their treatment guidelines
  • T-cell Engagers (TcEs) show promising activity in epNEC with high DLL3 expression, suggesting that DLL3 testing may become an important tool in the diagnostic work-up of these rare and hard-to-treat tumours
  • AI can be considered to improve the diagnosis of epNEC and provide consistency in DLL3 interpretation
