mCRPC
Conditions
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.
Interventions
Oral administration, 1.2 g twice daily (BID), taken 30 minutes before breakfast and dinner.
Intravenous infusion, 200 mg every 3 weeks (Q3W).
Maintenance of ADT using GnRH agonist or antagonist (e.g., Goserelin, Leuprorelin, Triptorelin, or Degarelix).

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Incidence of Adverse Events (AEs) | 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
| Measure | Time frame | Description |
|---|---|---|
| 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 | Defined as the proportion of subjects whose best overall response, assessed per RECIST 1.1 and PCWG3, is Complete Response (CR), Partial Response (PR), or Stable Disease (SD) . |
| Radiographic Progression-Free Survival (rPFS) | From baseline to primary completion, which may take up to 24 to 48 weeks | Defined as the time from treatment initiation to the first objective evidence of disease progression as assessed by radiographic imaging, or death from any cause, whichever occurs first. |
| Time to First Skeletal-Related Event (SRE) | From baseline to primary completion, which may take up to 24 to 48 weeks | Defined as the interval from the date of treatment initiation to the date of the first occurrence of any of the following clinically significant events attributable to bone metastasis: pathological fracture (vertebral or non-vertebral), palliative radiation therapy to bone for pain relief, surgical intervention to bone to prevent or treat a fracture or spinal cord compression, or confirmed spinal cord compression. |
