Novartis strengthens radioligand therapy pipeline with agreement to buy Mariana Oncology

RLTs, or radiopharmaceuticals, are a form of precision medicine that combines a tumor-targeting molecule (ligand) with a therapeutic radioisotope (a radioactive particle). RLTs bind to specific receptors 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.

“As pioneers in radioligand therapies, we are dedicated to building on our scientific leadership and expanding the breadth of these potentially transformative treatments to a broader range of cancer types,” said Shiva Malek, Global Head of Oncology for Biomedical Research at Novartis. “This acquisition brings to Novartis phenomenal talent and new capabilities in RLT research that complement our wide-ranging internal efforts to explore novel isotopes, combinations, disease areas, and more.”

As of now, Novartis has two approved RLTs for certain patients with metastatic castration-resistant prostate cancer and for certain types of gastroenteropancreatic neuroendocrine tumors. The company’s early and late pipeline has several programs in or entering the clinic, including a spectrum of studies and assets for prostate cancer, as well as other preclinical and discovery programs to identify the next wave of novel RLTs. 

Under the terms of the agreement, Novartis will make an upfront payment of USD 1 billion and additional USD 750 million in payments upon completion of pre-specified milestones.

The transaction is subject to customary closing conditions.
