Study Details

Study Description

Brief Summary

The death of prostate cancer patients is mainly due to metastatic castration-resistant prostate cancer. Though some new therapies has been tried to prolong the life-span of mCRPC patients, a dilemma was encountered for the drug-resistance. The PSMA RLT has been tested its efficacy and safety for the therapy of these patients. In our clinical trial, a new PSMA ligand will been used to be labeled with Ac225. This will be a prospective pilot clinical trial. 20 mCRPC patients who was incapable of 2rd ADT or chemotherapy will be recruited in this clinical tiral. The efficacy and safety of 225Ac-PSMA will be evaluated after the administration.

Arms and Interventions

Arm Intervention/Treatment
Experimental: mCRPC for PSMA RLT

225Ac-PSMA 100KBq/kg, iv. Totally 2 doses, every 8 weeks.

Drug: 225Ac-PSMA
all the patients will receive 225Ac-PSMA RLT for 2 cycles. The dosage will be calculated according to 100KBq/kg body weight. The drug will be administered by vein injection.

Outcome Measures

Primary Outcome Measures

  1. serum PSA level [through study completion, an average of 1 year]

    Serum prostate specific antigen (PSA) levels was used as the main marker of efficacy evaluation, and the changes of PSA level were divided into decrease > 50%, 30% ~ 50% and < 30%.

Secondary Outcome Measures

  1. Adverse Events and Serious Adverse Events [through study completion, an average of 1 year.]

    Adverse Events and Serious Adverse Events measured using National Cancer Institute Common Terminology Criteria for Adverse Events (NCI CTCAE) v5.0
