Dalpiciclib is Hengrui's CDK4/6 inhibitor, the first China-developed drug of the class, approved for hormone-driven advanced breast cancer on the DAWNA trials.
DAWNA-1 (361 patients, Nature Medicine 2021) showed median progression-free survival of 15.7 versus 7.2 months when dalpiciclib was added to fulvestrant after endocrine therapy (hazard ratio 0.42), the basis of NMPA approval in December 2021; DAWNA-2 with an aromatase inhibitor in the first line followed in 2023. Neutropenia is frequent, as with palbociclib. It gives Chinese patients a reimbursed domestic alternative to imported CDK4/6 inhibitors.
Selective inhibitor of cyclin-dependent kinases 4 and 6, preventing RB phosphorylation and G1 to S progression in hormone receptor-positive breast cancer. Connects to CDK4/6.
