Dalpiciclib Isethionate Tablets Combined With Abiraterone Acetate Tablets (I) and Prednisone Tablets (AA-P) Versus Placebo Combined With AA-P in Treatment of High-volume, Metastatic, Hormone-sensitive Prostate Cancer (mHSPC)
- Summary
- This study was to evaluate the safety and efficacy of dalcilide tablets in combination with AA-P in the treatment of subjects with high tumor burden mHSPC and to determine the second stage starting dose and progression-free survival（rPFS） based on BICR assessment

Adverse event (AE) incidence
Timeframe: approximately 63 months
PK： Steady-state trough concentrations of Dalsili and Abiraterone (Cmin, ss)
Timeframe: approximately 6 months
rPFS
Timeframe: approximately 63 months
Time from randomisation to radiologically confirmed progressive disease or death due to any cause
PSA response rate
Timeframe: approximately 63 months
In patients who had not started androgen deprivation prior to randomization, the proportion of patients whose PSA levels were ≥ 90% lower than baseline by the end of the study treatment week
ORR
Timeframe: approximately 63 months
Objective response rate+ The proportion of participants evaluated according to RECIST v1.1 and PCWG3 criteria that achieved predetermined tumor volume reduction and maintained the minimum duration was the sum of the proportion of complete and partial responses
Time to PSA progression
Timeframe: approximately 63 months
Time from randomisation to the first time of PSA progression
