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)
Study Details
Study Description
Brief 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

Outcome Measures
Primary Outcome Measures
- Adverse event (AE) incidence [approximately 63 months]
Secondary Outcome Measures
- PK： Steady-state trough concentrations of Dalsili and Abiraterone (Cmin, ss) [approximately 6 months]
- rPFS [approximately 63 months]
Time from randomisation to radiologically confirmed progressive disease or death due to any cause
- PSA response rate [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 [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 [approximately 63 months]
Time from randomisation to the first time of PSA progression
