An Exploratory Clinical Study Evaluating the Safety and Efficacy of Allogeneic CAR-NK Cell Therapy for Metastatic Castration-resistant Prostate Cancer (mCRPC)

This study introduces a new treatment approach for metastatic castration-resistant prostate cancer, a stage of disease that remains difficult to manage with current therapies. Prostate cancer is the second most common cancer in men worldwide, and many patients eventually progress to an advanced, treatment-resistant stage despite hormone therapy, newer hormonal agents, or chemotherapy. Patients with metastatic castration-resistant disease often face a poor prognosis, complications such as bone metastases, and significant impacts on quality of life, highlighting the urgent need for new treatment options. This research focuses on an innovative immunotherapy using allogeneic anti-PSMA CAR-NK cells, which are engineered natural killer cells designed to precisely recognize and kill prostate cancer cells expressing the prostate-specific membrane antigen. CAR-NK cells combine the natural tumor-killing ability of NK cells with enhanced targeting and reduced immune escape, offering a potentially safer and more effective strategy. Through this clinical study, the safety, tolerability, and preliminary effectiveness of anti-PSMA CAR-NK cell therapy will be evaluated, aiming to provide new evidence and expand future treatment possibilities for patients with advanced prostate cancer.
