Sanofi has entered an exclusive licensing agreement with RadioMedix, Inc., a U.S. clinical-stage biotech firm specializing in radiopharmaceuticals, and Orano Med, a French subsidiary of Orano Group focused on radioligand therapies (RLTs) for cancer treatment. The collaboration centers on AlphaMedix™ (212Pb-DOTAMTATE), a targeted alpha therapy (TAT) being evaluated for treating patients with metastatic, progressive neuroendocrine tumors (NETs) that express somatostatin receptors.
AlphaMedix™ is a peptide complex radiolabeled with lead-212 (212Pb), an alpha particle generator. Early clinical results showed a 62.5% durable response rate in reducing tumor burden, leading to its Breakthrough Therapy Designation by the U.S. FDA for gastroenteropancreatic neuroendocrine tumors (GEP-NETs).
Sanofi's Chief Medical Officer, Dietmar Berger, highlighted the potential of 212Pb as a transformative therapy for rare cancers, while Ebrahim S. Delpassand, CEO of RadioMedix, emphasized its role in pioneering nuclear oncology. Orano Med CEO Julien Dodet affirmed their commitment to advancing 212Pb-based therapies, developing a global platform for AlphaMedix™ manufacturing and distribution.
Sanofi will oversee global commercialization, while Orano Med handles manufacturing. The deal includes an upfront payment of €100 million, up to €220 million in sales milestones, and tiered royalties, pending regulatory approval. This agreement aligns with Sanofi's strategic focus on innovation in oncology, addressing hard-to-treat cancers through targeted therapies.
