| 简要概况 | This is an open-label study that includes three substudies of random distribution. First, a sample of the primary tumor will be obtained and will be analyzed by an immunohistochemical technique to determine several markers. Depending on the expression of these markers, the patients will be characterize as group 1 (Luminal phenotype), group 2 (Neuroendocrine phenotype) or group 3 (Atypical phenotype) and a random assignment will be performed to standard or experimental treatment. |

| 详细说明 | Metastatic castration-resistant prostate cancer (mCRPC) is a heterogenous disease with at least 3 intrinsic subtypes including luminal, neuroendocrine, and atypical phenotypes. Different subtypes have different prognosis and treatment sensitivity. Thus, it would be more suitable to administer different therapy in different subtypes. Therefore, the investigators designed this phase 2 randomized clinical trial to explore potential effective regimens in variable subtypes of mCRPC. Patients were first classified into Luminal type, Neuroendocrine type and Atypical type by immunohistochemistry exam of FKBP5/AR-WT/AR-v7/CgA/SYN/YAP1 in core needle biopsy and then randomized to received either standard or experimental treatment. 1. Group 1 (Luminal type): Standard treatment: Goserelin (3.75mg, once every 4 weeks)+Docetaxel (75 mg/m2 on day 1 every 3 weeks)+Prednisone (5 mg, twice daily) Experimental treatment: Goserelin (3.75mg, once every 4 weeks)+Abiraterone (1000 mg, once daily)+Prednisone (5 mg, twice daily) 2. Group 2 (Neuroendocrine type): Standard treatment: Goserelin (3.75mg, once every 4 weeks)+Docetaxel (75 mg/m2 on day 1 every 3 weeks)+Prednisone (5 mg, twice daily) Experimental treatment: Goserelin (3.75mg, once every 4 weeks)+Carboplatin (area under the curve 5 on day 1 every 3 weeks)+Docetaxel (75 mg/m2 on day 1 every 3 weeks)+Prednisone (5 mg, twice daily) 3. Group 3 (Atypical type): Standard treatment: Goserelin (3.75mg, once every 4 weeks)+Docetaxel (75 mg/m2 on day 1 every 3 weeks)+Prednisone (5 mg, twice daily) Experimental treatment: Goserelin (3.75mg, once every 4 weeks)+Abiraterone (1000 mg, once daily)+targeted therapy according to next Generation Sequencing (NGS)+Prednisone (5 mg, twice daily); or Goserelin (3.75mg, once every 4 weeks)+Abiraterone alone+Prednisone (5 mg, twice daily) if no druggable gene mutation detected. The detailed Individual treatment see below. The duration of chemotherapy is 6-10 cycles. Primary endpoint is the overall survival (OS) in each subtypes. Secondary endpoints include progression free survival (PFS), PSA response rate and safety. Tissue samples and blood samples will be collected at baseline and during treatment. There will be exploratory biomarkers analyses to identify predictive markers for efficacy in every subtypes. Targeted Therapy: Participants with druggable gene mutations will receive the corresponding molecular targeted drugs. 1. Participants with epidermal growth factor receptor (EGFR) gene mutation will receive Gefitinib, which inhibits a protein called EGFR that is thought to be a key factor in the development and progression of some cancers. 2. Participants with B-type Raf kinase (BRAF) gene mutations will receive Vemurafenib, which inhibits a protein called mitogen-activated or extracellular signal-regulated protein kinase kinase (MEK) that is thought to be a key factor in the development and progression of some cancers. 3. Participants with v-akt murine thymoma viral oncogene homologue 1 (AKT1) gene mutations will receive Celecoxib, which inhibits a protein called v-akt murine thymoma viral oncogene homologue (AKT) that is thought to be a key factor in the development and progression of some cancers. 4. Participants who have erythroblastic leukemia viral oncogene homolog 2 (ERBB2) gene mutation will receive Lapatinib, which inhibits some proteins that are thought to be key factors in the development and progression of some cancers. 5. Participants with PDGFRA/PDGFRB gene mutations will receive Sunitinib, which inhibits some proteins that are thought to be key factors in the development and progression of some cancers. 6. Participants with PIK3CA gene mutations will receive Everolimus, which inhibits a protein called AKT that is thought to be a key factor in the development and progression of some cancers. 7. Participants with DNA-repair gene defects will receive Olaparib, which inhibits poly ADP ribose polymerase (PARP). | ||
