  • History of splenectomy.
  • Presence of primary or secondary immunodeficiency disease.
  • History of uncontrolled seizures, central nervous system disorders, or psychotic loss of cognition.
  • History of chronic alcohol or drug abuse within 6 months prior to screening.
  • Unstable systemic diseases, such as active infection, liver cirrhosis, chronic renal failure, severe chronic lung diseases, etc.
  • Clinically severe pericardial effusion.
  • Not suitable for leukapheresis.
  • For any other reasons, the patients are believed not suitable for participation in this study by investigators.

Arms of the Study

Arm 1

Arm Type

Experimental

Arm Label

Prodencel Treated for mCRPC

Arm Description

Cohort 1: Each subject would receive Prodencel treatment at a dose of 5×10^6 cells every two weeks for a total of 3 doses. Cohort 2: Each subject would receive Prodencel treatment at a dose of 10×10^6 cells every two weeks for a total of 3 doses. Cohort 3: Each subject would receive Prodencel treatment at a dose of 15×10^6 cells every two weeks for a total of 3 doses. Cohort 4: The safe and effective dose from cohort 1-3 is recommended for booster immunization of cohort 4. Subjects will receive additional Prodencel treatment every 4 weeks, until disease progression or intolerance after the 3 doses of immune induction, to evaluate the safety and tolerability of the booster immunization.

5. Study Description

Brief Summary
This phase I clinical trial is to evaluate the safety of Prodencel (an autologous dendritic cell therapeutic tumor vaccine.) in patients with metastatic castration-resistant prostate cancer (mCRPC).
Detailed Description
This is a single arm pilot study to evaluate the safety of delivering a dendritic cell vaccine in fifteen to twenty-four (n=15-24) adult patients diagnosed with prostate adenocarcinoma after novel androgen-deprived therapy and docetaxel chemotherapy failure. The study is constructed in a 3+3 design for three steps of dose escalation with rigorous and mandatory safety monitoring. Subjects received the vaccine at a dose of 5-15×10^6 cells every two weeks for a total of 3 doses. A dose from cohort 1-3 is recommended for booster immunization every 4 weeks until disease progression or intolerance, to evaluate the safety and tolerability of the booster immunization of Prodencel. Subjects will be monitored for adverse events as dictated by CTCAE version 5.
