Study summary

What the protocol is testing.

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

DIETARY_SUPPLEMENT

LC-K76

Oral administration, 1.2 g twice daily (BID), taken 30 minutes before breakfast and dinner.

DRUG

Tislelizumab

Intravenous infusion, 200 mg every 3 weeks (Q3W).

DRUG

Standard Androgen Deprivation Therapy (ADT)

Outcomes

What the study measures.

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

Time frame · From baseline to primary completion, which may take up to 24 to 48 weeks

Disease control rate (DCR)

Time frame · 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)

Time frame · 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)

Time frame · 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.

Inclusion Criteria: 1. Male, aged 18 to 85 years. 2. Histologically confirmed prostate adenocarcinoma, without small cell carcinoma components. 3. Metastatic Castration-Resistant Prostate Cancer (mCRPC) with disease progression after at least one novel endocrine therapy (e.g., abiraterone or enzalutamide) and/or docetaxel chemotherapy. 4. Evidence of bone metastasis on PSMA-PET-CT or bone scan (ECT). 5. Serum testosterone at castration levels (\< 50 ng/dL or 1.75 nmol/L). 6. ECOG performance status ≤ 2. 7. Life expectancy \> 6 months. 8. Adequate bone marrow, hepatic, and renal function. 9. Willing to undergo biopsies before and during treatment Exclusion Criteria: 1. Lack of pathological evidence for prostate cancer. 2. Other primary malignant tumors active or requiring treatment within the past 3 years. 3. Has visceral metastases. 4. Poorly controlled diabetes after continuous insulin therapy. 5. Significant abnormalities in laboratory values at randomization (Hb \< 90 g/L; Neutrophils \< 1.5x10\^9/L; Platelets \< 75x10\^9/L; ALT/AST \> 2.5xULN; Bilirubin \> 1.5xULN; eGFR \< 60 mL/min/1.73m\^2) . 6. Severe cardiopulmonary disease or high-risk conditions. 7. Prior therapy with any immune checkpoint inhibitors (e.g., anti-PD-1/PD-L1). 8. Intolerance to anti-PD-1 monoclonal antibody or dandelion extracts. 9. History of severe drug allergies. 10. Factors affecting drug intake/absorption (e.g., swallowing difficulty, chronic diarrhea). 11. Concurrent psychiatric or neurological conditions
