Novartis drops phase 2 radioligand therapy, but CEO’s commitment to the modality unchanged

Novartis has discontinued a phase 2‑stage radioligand therapy (RLT) candidate, Lutetium‑NeoB (Lu‑NeoB), after early clinical data failed to support further development; the decision was not due to safety issues and ongoing patients remain on protocol.

The company maintains a broad radioligand pipeline with multiple RLTs in phase 1 across targets such as DLL3, HER2, and FAP, plus at least one FAP‑directed candidate in phase 2.

CEO Vas Narasimhan has publicly stated that Novartis’s commitment to the radioligand therapy modality is 'completely unchanged,' underscoring continued investment in RLTs despite this candidate’s termination.
