Molecular Partners AGFirst patients dosed in Phase 1/2a trial of MP0712, a novel Radio-DARPin therapy for DLL3-positive cancers.

Molecular Partners and Orano Med announced that the first patients have been dosed in the US multicenter Phase 1/2a study of MP0712, a DLL3-targeting Radio-DARPin carrying the therapeutic payload lead-212. The study is currently recruiting at five US sites, with additional sites planned to open this year, and dosing is ongoing in cohort 1 with patients moving to repeat dosing. MP0712 targets DLL3, a protein expressed in over 85% of small cell lung cancer tumors and other aggressive neuroendocrine tumors, while expression in healthy tissues is low. The trial employs a matched-pair approach using a diagnostic imaging agent with 203Pb-labeled MP0712 to predict tumor uptake before patients receive up to four doses of 212Pb-labeled MP0712 across up to four dose levels. Initial data are expected in the coming months, with comprehensive safety and efficacy data anticipated in 2027.
