Court victory paves the way for Curium’s plans to provide targeted radioligand therapy to U.S. patients with GEP-NETs

(Boston, MA – 18^th June, 2026) – Curium™ is pleased to announce that it has prevailed in the patent dispute brought by Novartis subsidiary Advanced Accelerator Applications against Curium™ concerning Curium’s Lutetium Lu 177 dotatate product. In the court decision issued yesterday by the Delaware U.S. District Court, Justice Noreika adjudicated that all relevant patent claims asserted by Novartis/AAA are invalid and not infringed by Curium™, representing a complete victory for Curium™. This favorable court decision paves the way for Curium’s plans to launch its Lutetium Lu 177 dotatate product in the U.S. and commercialize a therapy for the treatment of somatostatin receptor-positive gastroenteropancreatic neuroendocrine tumors (GEP-NETs), including foregut, midgut, and hindgut neuroendocrine tumors in adults across the United States.

Renaud Dehareng, Curium’s group chief executive officer, said: “We are pleased with the court’s decision. Curium™ is focused on building a durable theranostics platform that pairs our diagnostic leadership with targeted radioligand therapies — and doing so with the operational discipline required to serve patients reliably at scale.”

Michael Patterson, Curium’s North American chief executive officer, said: “This outcome brings Curium a step closer in our mission to deliver what patients, clinicians and health systems need: timely access to critical targeted radiopharmaceuticals. Curium™ has more than 100 years of experience in nuclear medicine and a long-standing commitment of over 30 years to the NET community, supplying diagnostic products that help detect neuroendocrine tumors today and a pipeline of investigational drugs in development.”
