Interventions
DRUGTrilaciclib and Topoisomerase I inhibitor type ADC drugs
Patients who can use topoisomerase I inhibitor type ADC drugs. Intravenous infusion of Trilaciclib should be administered 4 hours before using topoisomerase I inhibitor type ADC drugs. Trilaciclib was used for a total of 2 cycles.
