Insights
The collaboration between Molecular Partners and Orano Med marks a significant advancement in the field of radioligand therapy, particularly with the use of 212Pb (lead-212) as a radioactive payload in Radio-DARPin therapeutics (RDTs). The ability of RDTs to minimize kidney damage, a common side effect in protein-based radioligand therapies, while maintaining high tumor uptake, could represent a major therapeutic breakthrough. This is especially pertinent for cancers expressing DLL3, like small-cell lung cancer, where there is a need for highly selective treatment options. The co-development agreement could accelerate the availability of novel treatments, potentially improving outcomes for patients with hard-to-treat cancers. The anticipated first-in-human studies in 2025 will be a critical milestone to evaluate the safety and efficacy of these novel RDTs.
The strategic partnership between Molecular Partners and Orano Med is poised to create shareholder value through the development of cutting-edge cancer treatments. The shared cost model reduces financial risk for both parties while potentially speeding up the RDTs' path to market. The exclusive development of DLL3 as a RDT target may also provide a competitive edge in the oncology market. However, investors should monitor the progression of preclinical and clinical trials, as any setbacks could affect the companies' financial projections and stock performance. Moreover, the successful commercialization of these therapies could hinge on the ability to navigate regulatory hurdles and secure favorable reimbursement rates.
In the context of the broader biotech and pharmaceutical industry, collaborations like the one between Molecular Partners and Orano Med are indicative of a trend towards precision medicine. The focus on targeted alpha therapies aligns with the industry's move towards more personalized and effective cancer treatments. The choice of DLL3 as a target reflects a strategic focus on niche oncology segments where patients have limited treatment options. If successful, this partnership could catalyze further investments and innovations in the radioligand therapy space, potentially reshaping treatment paradigms and driving market growth.
- Collaboration leverages lead-based (212Pb) alpha emitter expertise and supply of Orano Med with Molecular Partners’ leadership in DARPins for tumor-targeted delivery of radioactive payloads
- Co-Development agreement covers multiple oncology targets, including DLL3
- Companies anticipate first-in-human studies in 2025
ZURICH-SCHLIEREN, Switzerland and CONCORD, Mass., and PARIS, Jan. 05, 2024 (GLOBE NEWSWIRE) -- Ad hoc announcement pursuant to Art. 53 LR 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, and Orano Med, a pioneer in targeted alpha therapy, have announced a collaboration to develop novel Radio-DARPin therapeutics (RDTs) that use Orano Med’s 212Pb radioisotope as a payload to selectively kill cancer cells. Both companies will leverage their unique capabilities to enable rapid clinical development and agree to share costs for preclinical and clinical development for multiple oncology targets, the first of which is DLL3.
The partnership is based upon strong preclinical data supporting a highly differentiated profile for 212Pb-based RDTs. Besides strong binding to target proteins and selective delivery of radioactive payloads, these data have also indicated the ability of RDTs to minimize kidney damage often associated with protein-based radioligand therapies while maintaining high tumor uptake. This agreement represents the first co-development deal for Molecular Partners and Orano Med. Both companies are developing additional radioligand therapy candidates in partnership with other companies, with Molecular Partners having announced its first collaboration with Novartis in December 2021.
“Orano Med provides extensive expertise and a secure supply of a powerful, highly focused source of radiation for precision cancer treatment, expanding our RDT portfolio in new directions,” said Patrick Amstutz, Ph.D., CEO of Molecular Partners. “While we have been able to demonstrate the potent and highly selective targeting of tumor cells by DARPins, it is imperative that we align ourselves with our partners who have the scientific, technical and logistical expertise to develop, manufacture and supply radiotherapeutics. Having worked with the Orano Med team for many months, we are excited and confident in their expertise and capabilities, as well as by their ambition to co-develop molecules in the clinic. We look forward to working jointly to bring these RDT programs into the clinics as rapidly as possible.”
“We are extremely excited to start this collaboration with Molecular Partners and to unlock the full potential of their DARPin platform in the field of radioligand therapies. We have been impressed by the versatility of the DARPin platform and by their in-house expertise in optimizing DARPins for applications in targeted alpha therapies. This collaboration enables us to meet the 3 key success factors in this field: leveraging a safe, convenient, and potent radioactive payload, achieving effective vectorization, and mastering the intricacies of the supply chain. This collaboration will further diversify our targeting approach, which combines the unique properties of 212Pb and Orano Med’s unparalleled global manufacturing supply chain. It will expedite the development of 212Pb-based radiotherapies to bring new breakthrough solutions for patients living with cancer”, said Julien Dodet, CEO of Orano Med.
Under the terms of the co-development agreement, Molecular Partner’s previously disclosed RDT target DLL3 (delta-like ligand 3) will be included in the partnership with Orano Med. Expression of DLL3 is low in healthy tissue but significantly increased in certain tumor types, such as small-cell lung cancer, providing an opportunity for selective tumor-targeting. DLL3 will be exclusively developed by Molecular Partners and Orano Med as a RDT target. Molecular Partners will maintain the option to explore DLL3 for targeted therapy outside of the radiotherapy space.
Both companies commit to sharing the cost of preclinical and clinical development with additional commitments to supply of their respective materials. Additional agreements are being put in place for future development and commercialization of any potential programs that proceed into the clinical stage of development.
About DARPin Therapeutics
DARPin therapeutics are a new class of custom-built protein therapeutics based on natural binding proteins that open a new dimension of multi-functionality and multi-target specificity in drug design. A single DARPin candidate can engage more than five targets, and its flexible architecture and small size offer benefits over other currently available protein therapeutics. DARPin therapeutics have been clinically validated in thousands of patients in multiple indications, including through to registration via the development of abicipar, a DARPin drug candidate for ophthalmological indications. The DARPin platform is a fast and cost-effective drug discovery engine, producing drug candidates with optimized properties for development and very high production yields.

About Orano Med SAS
Orano Med is a clinical-stage biotechnology company which develops a new generation of targeted therapies against cancer using the unique properties of lead-212 (212Pb), a rare alpha-emitting radioisotope and one of the more potent therapeutic payloads against cancer cells known as Targeted Alpha-Emitter Therapy (TAT). The company develops several treatments using 212Pb combined with various targeting agents. Orano Med has 212Pb manufacturing facilities, laboratories, and R&D centers in France and in the US and is currently investing to further expand its GMP-manufacturing capacities for 212Pb radiolabeled pharmaceuticals in North America and Europe.

About Targeted Alpha Therapy
Targeted alpha therapy (TAT) relies on a simple concept: combining the ability of biological molecules to target cancer cells with the short-range cell-killing capabilities of alpha-emitting radioisotopes. Alpha decay consists of the emission of a helium nucleus (alpha particle) together with very high linear energy transfer and a range emission of only few cell layers, resulting in irreparable double strand DNA breaks in cells adjacent only to area of alpha emission. This approach results in an increased cytotoxic potential toward cancer cells while limiting toxicity to nearby healthy cells. As a result, alpha emitters are considered as the most powerful payloads to be found for targeted therapies.
