Sino Biopharmaceutical reported promising Phase II data for culmerciclib, an oral CDK2/4/6 inhibitor, in treating resistant breast cancer. The drug showed a 32.4% objective response rate and manageable safety profile when combined with fulvestrant. These results support its regulatory approval in China and potential to address resistance to existing therapies. With a fully enrolled Phase III trial underway, culmerciclib aims to strengthen Sino Biopharm's oncology portfolio. Analysts maintain a 'Buy' rating on the stock.
