Molecular Partners Announces Upcoming Top-Rated Oral Presentation on MP0712, a ²¹²Pb-labeled Radio-DARPin Therapeutic targeting DLL3 for Small Cell Lung Cancer co-developed with Orano Med, at EANM 2024

First RDT candidate MP0712 shows low kidney accumulation and high tumor uptake in preclinical models

MP0712 treatment leads to strong tumor growth inhibition with a good safety profile in vivo

ZURICH-SCHLIEREN, Switzerland and CONCORD, Mass., Sept. 27, 2024 (GLOBE NEWSWIRE) -- Molecular Partners AG (SIX: MOLN; NASDAQ: MOLN), a clinical-stage biotech company developing a new class of custom-built protein drugs known as DARPin therapeutics, today announced that the Company will present on its lead-212 (²¹²Pb)-labeled Radio-DARPin Therapeutic (RDT) targeting delta-like ligand 3 (DLL3) co-developed with Orano Med, at the European Assocation of Nuclear Medicine (EANM) Congress which runs October 19-23, 2024 in Hamburg, Germany.

The presentation details are as follows:

Title: Preclinical Assessment of Lead-212 (²¹²Pb) Radio-DARPin Therapeutic (RDT)
Targeting Delta-like Ligand 3 (DLL3) in Small Cell Lung Cancer (SCLC)
Presentation Number: OP-535
Session Number: 1204
Session Title: M2M Track – Top Rated Oral Presentation (TROP) Session: Radiopharmaceutical Sciences + Translational Molecular Imaging & Therapy Committee: From Radionuclide to Clinical Translation
Session Timing & Location: October 22, 2024; 8:00-9:30 a.m. CET, Hall X1–X4
Presentation Timing: October 22, 2024; 9:20-9:30 a.m. CET

The presentation will be made available on Molecular Partners ’ website after the conference.

Molecular Partners is developing a unique and innovative RDT platform for targeted delivery of radioactive payloads to solid tumors. Due to their small size, high specificity and affinity, DARPins are well-suited as vector for efficient delivery of therapeutic radionuclides. In June 2024, Molecular Partners , together with Targeted Alpha Therapy pioneers Orano Med, announced MP0712, a ²¹²Pb-labeled DLL3-targeting radiopharmaceutical as their first co-developed RDT candidate.

DLL3 is a priority target for radiopharmaceutical therapy thanks to its abundant expression in tumors of patients with SCLC (>85%) and other aggressive neuroendocrine tumors, while expression in healthy tissues is low.

At EANM 2024, Molecular Partners will present their preclinical results supporting MP0712 as a promising treatment candidate for SCLC, with an attractive biodistribution profile, potent antitumor activity and a good safety profile.

About DARPin Therapeutics
DARPin (Designed Ankyrin Repeat Protein) therapeutics are a new class of custom-built protein drugs based on natural binding proteins that open new dimensions of multi-functionality and multi-target specificity in drug design. The flexible architecture, intrinsic potential for high affinity and specificity, small size and high stability of DARPins offer benefits to drug design over other currently available protein-based therapeutics. DARPin candidates can be radically simple, with a single DARPin unit acting as the delivery vector to a specific target; or multispecific, with the possibility of engaging more than five targets, and combining multiple and conditional functionalities in a unique DARPin drug candidate. The DARPin platform is designed to be a rapid and cost-effective drug discovery engine, producing drug candidates with optimized properties and high production yields. DARPin therapeutics have been clinically validated across several therapeutic areas and developed through to the registrational stage.
