Daiichi Sankyo (DSNKY) — Congressional Trading Activity

Daiichi Sankyo was established by the merger of Daiichi Pharmaceuticals and Sankyo in 2005. As of 2024, approximately one quarter of revenue comes from its Japan businesses, which will shrink in the future as the company expands its global footprint. Its primary growth driver is its leading platform of antibody drug conjugates, or ADCs. Its lead ADCs are Enhertu (HER2), Datroway (TROP2), I-DXd (B7-H3), HER3-DXd (HER3), and R-DXd (CDH6). Enhertu was first approved in the US in December 2019, and Datroway was first approved in January 2025.
