Brief summary: The purpose of this study is to evaluate the feasibility, safety and oncological efficacy of hormonal therapy combined with autologous Tcm cells for patients with advanced prostate cancer.

Detailed description: Adoptive cancer immunotherapy,the infusion of tumor-reactive T cells to patients,represents a promising approach for the treatment of advanced metastatic disease.It has been shown that central memory T cells (Tcm) were the optimal antitumor T cells for adoptive cell transfer in cancer patients.However,the potential of autologous Tcm cells to treat the advanced prostate cancer has not been evaluated.

This is an open-label pilot study to determine if the infusion of autologous Tcm cells combined with hormonal therapy is safe and effective for the treatment of advanced prostate cancer.This study will have the following two cohorts:Cohort A) metastatic hormone-sensitive prostate cancer (mHSPC) treated with maximal androgen blockade plus autologous Tcm cells and Cohort B) metastatic castration-resistant prostate cancer (mCRPC) treated with abiraterone acetate plus autologous Tcm cells.A total of 60 evaluable subjects will be enrolled over an enrollment period of 24 months.The study is planned to enroll approximately 30 evaluable subjects in each treatment cohort.

Eligibility criteria: Inclusion Criteria:

* Subjects who understand and sign the consent form for this study
* Males age ≥18 years

* Expected survival time of at least 24 months
* Adequate hematologic, renal, and liver function: WBC greater than 3.5 x 109/L; Absolute neutrophils count greater than 1.5 x 109/L; Platelet count greater than 80 x 109/L; Hemoglobin at least 90g/L; AST less than 2 x upper limit of normal (ULN); Creatinine less than 1.5 x ULN
* No obvious abnormalities in the electrocardiogram

Exclusion Criteria:

* The subject has serious diseases of respiratory, nervous or mental system
* Subject with immune disease, auto-immune disease requires systemic ongoing immunosuppressive therapy
* The subject has problems with drug or alcohol abuse
* Major surgery within 4 weeks of enrollment
* Prior autologous bone marrow transplantation within 4 weeks of enrollment
* The subject has participated in any other therapeutic clinical trial with an experimental drug in the 4 weeks prior to this trial
* The subject has any other unsuitable or adverse condition to be determined by the investigator
* Any medical intervention or any circumstances that could compromise the safety and compliance of the trial subjects
