#DLL3
Great analysis of DLL3 expression in SCLC and difficult to treat neuroendocrine neoplasms. Excited to see more biomarker driven approaches to advance care in such needed spaces.

DLL3 expression in high-grade NENs? Not rare at all! Check out this large study. 64% of NECs pos, 42% lung NETs, but only 5% GEPNETs are pos with the exception of G3 NETs which are 20% mod or strongly pos. DLL3-directed trials coming but not for G3 NETs.

DLL3 downregulation could be the expected mechanism of resistance to the tarlatamab BiTE in SCLC. This small study shows SCLC subtype switching, suggesting that intra-tumoral heterogeneity with pre-existing DLL3-low ASCL1-neg SCLC cells is an “easier” mechanism? Interesting! tinyurl.com/ye29dx6v

🌟No1: DLL3/T-cell Engagers (Tarlatamab/ Obrixtamig)

Those agents engage neuroendocrine cells expressing DLL3 to T-lymphocytes via TCR binding. Breakthrough FDA approval based on phase 2 data, including impressive ORR of 40% and mOS of 14.2 m. Phase 3 results vs SoC highly anticipated in 2025

Finally, great story re: evolution of bispecific T cell enagager (BiTE) - Dr Martijn Lolkema @amgen.bsky.social.

A journey re:
• Blinatumomab, CD19
• Tarlatamab, DLL3
• Tebentafusp, gp100
• Xaluritamig, STEAP1
etc

To navigate current challenges, more innovative technologies emerging! 🚀 #ESMOTAT25
