At a time when most biopharmas in China are focused on developing generic drugs and biosimilars, Grayson says RuiYi has taken a riskier approach by targeting wholly new biological and molecular compounds.

RuiYi’s predecessor company was founded in San Diego in late 2007 to advance new technology for creating genetically engineered protein drugs, with the potential to bind more tightly than traditional antibodies do with their cellular targets. But Grayson said it became clear … Next Page »
