About us

We develop boron-based drugs and other medical products

Established in Japan in 2007, Stella Pharma is a therapeutic drug research and development company.

Our development focus in recent years has been on boron compounds, particularly those for use in boron neutron capture therapy. BNCT is a form of cancer radiation therapy that is gaining in medical prominence due to its innovative approach in selectively destroying cancer cells, the ultimate way to fight cancer.

Using proprietary technology for concentrating boron, Stella Pharma leads the industry in the development of boron compounds that are essential for BNCT.
