As radiopharmaceuticals continue their hot streak, one of the few players with a marketed product, ITM Isotope Technologies Munich, has pulled in additional funding to help advance its lead pipeline candidate. The firm has secured a new investment of €188 million ($204 million), led by previous backer Temasek, with participation from BlackRock, Qatar Investment Authority and ATHOS.
ITM currently markets EndolucinBeta, which uses lutetium-177 (177Lu) for radiolabelling of other medicines, and TOCscan/Sogacin, which uses gallium (68Ga) edotreotide for diagnosing neuroendocrine tumours (NETs). While the two products are sold in a handful of European countries, ITM's pipeline has loftier ambitions and is stacked with a number of targeted radionuclide therapies based not only on 177Lu and 68Ga, but also on actinium-225 (225Ac), fluorine-18 and terbium-161.
Phase III nearing completion
Its lead asset, ITM-11 (177Lu-edotreotide), is nearing the end of Phase III testing in gastroenteropancreatic NETs (GEP-NETs). The late-stage COMPETE study is evaluating ITM-11 in patients with Grade 1 - 2 GEP-NETs, while the COMPOSE trial is for patients with well-differentiated high Grade 2 - 3 GEP-NETs. With this in mind, ITM will use some of the proceeds from the latest financing to “prepare commercial readiness” of ITM-11.
“We have reached key milestones since our last financing round including advancing our pipeline with novel targets in multiple oncology indications,” remarked CEO Steffen Schuster. Almost exactly a year ago to the day, ITM announced a haul of €255 million – again led by Temasek – building on the €58 million it raised in 2022 and €114 million it secured in the prior year.
Aside from its internal pipeline, ITM recently launched a joint venture to produce 225Ac, while it has several supply agreements in place for 177Lu, including with Telix Pharmaceuticals and Endocyte, the latter now part of Novartis. In fact, the Swiss drugmaker is one of the key players in the radiopharmaceutical space, with its marketed products including Lutathera (177Lu dotatate) for GEP-NETs and the prostate cancer therapy Pluvicto (177Lu vipivotide tetraxetan). However, Novartis itself has faced production issues for Pluvicto, and only recently gained clearance for a new US radioligand manufacturing facility to help it keep up with demand.
ITM plans to put some of the new funding toward ramping up its in-house manufacturing capacities for 177Lu and expand these to new radioisotopes including 225Ac. ITM said it will use the radioisotopes not only for its own pipeline, but also provide them to its global supply network.
