Mariana Oncology, a Novartis Company, Announces $50M Expansion of Radioligand Therapy R&D Facilities
Investment doubles footprint in Watertown, Massachusetts; enhances radioligand therapy research and development capabilities
Watertown, Mass., June 20, 2025 – Mariana Oncology, a wholly owned subsidiary of Novartis focused on discovering and advancing next-generation radioligand therapies (RLTs), today announced plans for a $50M investment to expand its facilities in Watertown, MA. Encompassing approximately 30,000 square feet of new laboratory and office space, the expansion nearly doubles Mariana’s current footprint and will strengthen R&D capabilities to accelerate breakthroughs and deliver next-generation RLTs.
“Today’s announcement represents a significant milestone in the mission of Mariana and Novartis to innovate and deliver transformative new medicines for patients living with cancer,” said Fred Zecri, PhD, Chief Scientific Officer and Site Head for Mariana Oncology. “Expanding our radioligand therapy R&D capabilities positions us to further strengthen our pipeline and early-stage clinical programs and accelerate the development of promising new medicines."
“As a leader in the field, Novartis is committed to pioneering radioligand therapy science and accelerating the advancement of new treatments that have the potential to help patients with difficult-to-treat cancers,” said Shiva Malek, PhD, Global Head of Oncology for Novartis Biomedical Research. “This expansion will greatly enhance the capabilities of the Mariana team, complementing global efforts across Novartis to build on our deep expertise with RLTs and bring forward next-generation options for patients.”
Mariana Oncology serves as a primary research and drug discovery hub and is a key driver of RLT R&D activities for Novartis. The expansion further bolsters the commitment by Novartis to invest in and expand its overall US-based manufacturing and R&D footprint. Mariana has built a robust portfolio of discovery and clinical RLT programs across a range of solid tumor indications, including lung, breast, and prostate.
About Radioligand Therapy
Radioligand therapy is a form of precision medicine that combines a tumor-targeting molecule (ligand) with a therapeutic radioisotope (a radioactive particle). RLTs bind to specific receptors highly expressed on the surface of certain types of tumors. Once bound to a target cell, emissions from the therapeutic radioisotope cause DNA damage that can inhibit cell growth and replication and potentially trigger cell death. This targeted approach enables the delivery of radiation to the tumor, while limiting damage to the surrounding cells.
