Venture financing for innovative radiopharmaceutical drugs witnessed an approximately 550% increase from $63m in 2017 to $408m in 2023 YTD (year-to-date) total deal value in the US, according to GlobalData’s Pharma Intelligence Center Deals Database. In September 2023, Eli Lilly (Lilly) invested $175m in a Series B financing round for US-based biotech, Mariana Oncology, for their lead preclinical drug for small cell lung cancer, MC-339, and anticipate their drug to enter clinical trials next year.

Radiopharmaceutical drugs have a radioisotope bound to a drug or monoclonal antibody to enable precise detection through nuclear imaging and target directly towards the tumour cells. Since radiopharmaceuticals present fewer side effects than traditional radiation therapy and effectively target cancer cells, this has sparked considerable investor venture funding. There are a growing number of companies developing early-stage radiopharmaceutical drugs with the majority in discovery and preclinical stages of development seeing boosted interest from investors.
