Basel-based NUCLIDIUM, a clinical-stage radiopharmaceutical company developing a proprietary copper-based theranostic platform, today announced the successful closing of its Series B financing round, raising €84 million.
The round was led by Kurma Growth Opportunities Fund, Angelini Ventures, Wellington Partners, and Neva SGR (Intesa Sanpaolo Group), with participation from DeepTech & Climate Fonds (DTCF), Bayern Kapital, Vives Partners, Eurazeo, NRW.BANK and HighLight Capital, as well as existing investors.
“NUCLIDIUM is entering the next clinical phases with its lead compounds to diagnose and treat metastatic prostate, neuroendocrine tumors and breast cancer,” said Leila Jaafar, PhD, CEO and Co-Founder of NUCLIDIUM. “Our copper-based radiotheranostics are developed for seamless use in hospital workflows, care delivery and waste management, making these therapies more accessible worldwide. Our groundbreaking next generation copper theranostic platform also allows us to rapidly develop new targets across a wider range of cancers, particularly those highly relevant to women’s health.”
Founded in 2017, NUCLIDIUM AG is a clinical-stage BioTech company innovating the development of next-generation copper-based radiopharmaceuticals for the diagnosis and treatment of cancer.
Leveraging copper isotopes – Copper-61 for diagnostics and Copper-67 for therapeutics – NUCLIDIUM is creating a differentiated platform with the potential to overcome existing limitations in radiotheranostics.
NUCLIDIUM says they are committed to expanding the reach and efficacy of radiotheranostics, including addressing critical unmet medical needs in oncology and women’s health.
NUCLIDIUM’s differentiated platform links tumor-targeting molecules with copper isotopes – Copper-61 for diagnostics and Copper-67 for therapeutics – to address current limitations in radiotheranostics, such as suboptimal clinical efficacy and complex manufacturing.
“VIVES Partners is thrilled to be among the contributors in this significant fundraising round,” said Sandra Schoors, partner at VIVES Partners. “We have a strong belief in the potential of Nuclidium’s copper-based platform as a novel radiotheranostic. The company’s innovative approach tackles the critical limitations in current radiopharmaceutical methods, paving the way for more effective and accessible cancer treatments. We are excited to support this groundbreaking technology and look forward to its transformative impact on healthcare.”
Diagnostic results from initial clinical trials in these indications show superior lesion detection and higher tumor-to-background ratios compared with clinically approved tracers. Initial data were recently presented at SNMMI 2025 by Dr Gary Ulaner, MD, PhD highlighting a favorable safety profile and potentially improved imaging performance of 61Cu-NuriPro™ compared to current PET imaging standards, suggesting strong clinical promise and broader potential for 61Cu/67Cu theranostic pairing.
Early therapeutic data from the two lead compounds, NuriPro™ and TraceNET™, reportedly show strong tumor-to-background ratios in metastatic prostate cancer and neuroendocrine tumors including breast cancer.
“This significant Series B financing reflects the confidence of our investors in NUCLIDIUM’s vision and the transformative potential for the diagnostic and therapeutic industry in oncology and nuclear medicine,” said Tony Rosenberg, Chairman of the NUCLIDIUM Board. “With this backing, we are positioned to accelerate clinical development, broaden patient access globally, and reinforce our commitment to innovation in precision oncology. I am delighted to welcome our new Board and advisory members, whose deep expertise will further strengthen NUCLIDIUM’s leadership in radiopharmaceuticals.”
With this financing, NUCLIDIUM will continue expanding its worldwide production and manufacturing network for diagnostics and therapeutics, growing its international team, and strengthening strategic collaborations with hospitals and academic centres, initially across Europe and North America.
The proceeds will also be used to advance the clinical development of NUCLIDIUM’s Copper-61/Copper-67 (61Cu/67Cu) theranostic pipeline across multiple oncology indications.
In conjunction with the financing round, Daniel Parera, MD, Partner at Kurma Partners, Regina Hodits, PhD, Managing Director at Angelini Ventures, and Liliana Nordbakk, Partner Life Sciences at Neva SGR, will join NUCLIDIUM’s Board of Directors.
“NUCLIDIUM’s platform stands out in a rapidly evolving field and will change how radiotheranostic care is delivered. This investment reflects our strong conviction in the future of precision medicine and our belief in NUCLIDIUM’s potential to scale as a next-generation company – an ambition shared across a strong European syndicate,” added Daniel Parera, MD, Partner at Kurma Partners, Regina Hodits, PhD, Managing Director at Angelini Ventures, and Liliana Nordbakk, Partner Life Sciences at Neva SGR for all participating investors.
