New hope for tough prostate cancer: experimental combo targets resistant tumors
NCT ID NCT07389187
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This early-stage study tests a new drug (LC-K76) combined with an immunotherapy (Tislelizumab) and hormone therapy in 10 men with metastatic castration-resistant prostate cancer that has worsened after standard treatments. The goal is to check safety and see if the combination can shrink tumors or slow the disease. Participants take oral and intravenous medications for 24 weeks.

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
