Overview
Brief Summary
This open-label, single-arm study evaluates the safety and preliminary efficacy of LC-K76 combined with Tislelizumab and ADT in 10 patients with Metastatic Castration-Resistant Prostate Cancer (mCRPC) who progressed on prior therapies. Participants will receive oral LC-K76 and intravenous Tislelizumab for a 24-week treatment period.

Outcomes
Primary Outcomes
Incidence of Adverse Events (AEs)
Time Frame: From baseline to primary completion, which may take up to 24 to 48 weeks
The Incidence of Adverse Events is defined as the proportion of subjects in a clinical trial who experience at least one Adverse Event (AE) during the defined observation period, which is assessed by CTCAE 5.0.
Secondary Outcomes
- PSA Response Rate(From baseline to primary completion, which may take up to 24 to 48 weeks)
- Disease control rate (DCR)(From baseline to primary completion, which may take up to 24 to 48 weeks)
- Radiographic Progression-Free Survival (rPFS)(From baseline to primary completion, which may take up to 24 to 48 weeks)
- Time to First Skeletal-Related Event (SRE)(From baseline to primary completion, which may take up to 24 to 48 weeks)
