177Lu-PSMA-617 Combined With Darolutamide in Neoadjuvant Treatment of High-risk Localized Prostate Cancer: a Prospective, Single-arm, Multi-center Clinical Trial
The goal of this clinical trial is to explore the efficacy and safety of darolutamide combined with 177Lu-PSMA-617 in treating high-risk localized prostate cancer patients who are scheduled to undergo radical prostatectomy. The main questions it aims to answer are:
Does this combination treatment improve the pathological complete response rate (pCR)? What is the minimal residual disease (MRD) rate in these patients? What are the safety profiles and any adverse effects associated with this treatment? Researchers will compare the combination of darolutamide and 177Lu-PSMA-617 to a placebo to see if the combination is effective in treating high-risk localized prostate cancer.
Participants will:
Receive either darolutamide combined with 177Lu-PSMA-617 or a placebo every day for 12 weeks.
Visit the clinic every 6 weeks for checkups and tests. Keep a diary of their symptoms and any side effects experienced during the treatment.
Undergo imaging tests, including prostate MRI and PSMA PET/CT, before surgery and during follow-up.
