MP0712, the first anti-DLL3 212Pb radio-DARPin (RDT) candidate for targeted radiotherapy of small cell lung cancer (SCLC) (AACR 2025) - "In NCI-H82 tumors, median survival duration increased up to 3-fold with MP0317 compared with the buffer control. MP0712 also showed a favorable safety profile in vivo up to 30µCi. These preclinical results support our 212Pb-based RDT against DLL3 as a promising treatment option for SCLC, with encouraging in vivo antitumor activity and a good safety profile for our first DLL3-targeting 212Pb-RDT candidate for further development into the clinic."

Molecular Partners presents new preclinical data on Radio-DARPin and Switch-DARPin programs at AACR 2025 (GlobeNewswire) - "Preclinical data presented on MP0712, a DLL3-targeting and 212Pb-labeled Radio-DARPin, show a high tumor uptake and a favorable safety profile for MP0712, with good efficacy and tumor reduction in mouse models matching clinically relevant DLL3 expression levels. With these data, the IND-enabling package is complete; IND filing and initial first-in-human clinical data are expected in 2025. DLL3 is a promising target for radioligand therapy as it is highly upregulated in small cell lung cancer and other high-grade neuroendocrine tumors, while not expressed in healthy tissues."

Molecular Partners and Orano Med Present Additional Positive Preclinical Data Supporting DLL3 Targeting Radio-DARPin Therapeutic Candidate MP0712 at EANM 2024 (GlobeNewswire) - "Molecular Partners and Orano Med anticipate initiating first-in-human studies, pending regulatory clearance, in 2025. Initial clinical data of MP0712 is also anticipated in 2025....Dose-range finding studies in mice confirmed that treatment at a clinically relevant dosage was well tolerated, supporting a favorable safety profile. Finally, MP0712 led to strong and dose-dependent efficacy in mice bearing established tumors with clinically-relevant levels of DLL3 expression and at a clinically-relevant dose, as compared to a positive control of a radiolabelled anti-DLL3 antibody rovalpituzumab (Rova)."
