Outcome Measures

Primary Outcome Measures :

1. Objective response rate (ORR) [ Time Frame: 2 years ]
   The percentage of patients with measureable disease at baseline who achieved a complete or partial response in their soft tissue disease using the Response Evaluation Criteria in Solid Tumors (RECIST) version 1.1 criteria
2. AE [ Time Frame: 2 years ]
   The type, frequency, severity, timing, seriousness, and relationship to study therapy

Secondary Outcome Measures :

1. PSA response rate [ Time Frame: 2 years ]
   After the continuous therapy from randomisation to the end of the 12 weeks, the percentage of patients whose levels of PSA decreased by more than 50% compared with baseline
2. Time to prostate specific antigen (PSA) progression [ Time Frame: 2 years ]
   Time from randomisation to the first time of PSA progression according to the criterion of PCGW3
3. Radiographic Progression Free Survival(rPFS) [ Time Frame: 2 years ]
   Time from randomisation to radiologically confirmed progressive disease or death due to any cause
4. OS [ Time Frame: 2 years ]
   Time from randomisation to death due to any cause
5. DoR [ Time Frame: 2 years ]
   Time from radiologically confirmed reponse to radiologically confirmed progressive disease or death
6. Time to skeletal-related events [ Time Frame: 2 years ]
   Time from randomisation to the first occurrence of a skeletal-related event. The skeletal-related event is defined as the occurrence of either pathological or clinical fracture, spinal cord compression, bone-related radiotherapy or surgery

Eligibility Criteria

• Ages Eligible for Study: 18 Years to 120 Years (Adult, Older Adult)

• Disease progressed within 6 months prior to inclusion in the study. Disease progression defined as the occurrence of one or more of the following three items at the same time of castration：

  ① PSA progression，defined as at least twice increases in PSA level (interval time ≥ 1 week, and PSA level at screening should be ≥ 2ng / ml)

  ②Disease progression as defined in RECIST 1.1

  ③Bone disease progression defined by PCWG3，more than 2 new lesions in bone scan

• Metastatic lesions with radiologica evidence， measurable non-bone target lesions
• Adequate hepatic, renal, heart, and hematologic functions (no blood transfusion or hematopoietic growth factor treatment within 2 weeks before blood routine screening)：platelets>80×10^9/L，neutrophil>1.5×10^9/L, Hb≥90 g/L,total bilirubin≤1.5×limit of normal(ULN), ALT and AST ≤2.5×ULN（≤5×ULN with liver metastasis），blood urea nitrogen and creatinine≤1.5×ULN
• Willingness and ability to comply with scheduled visits, treatment plans, laboratory tests, and other study procedure
• Willing to participate in this clinical trial, understand the research procedures and have signed informed consent

Exclusion Criteria:

• Prior treatment with MEK inhibitors，including trametinib
• Washout period from the end of any previous anti-tumor treatment (including radiotherapy, chemotherapy, surgery, molecular targeted therapy, immunotherapy, androgen receptor inhibitors, CYP-17 inhibitors, 5 α-reductase inhibitors, estrogen, progesterone drugs, etc) to the first administration of the study drug less than 1 week (bicalutamide elution period < 2 weeks)
• Plant drugs (e.g. Saw Palmetto) or steroids that may reduce PSA levels within 4 weeks, or planned to be used during the trial period (except for temporary steroid drugs for preventing or treating allergies)
• Plan to receive any other anti-tumor treatment during this trial
• Last drug administration from other clinical trials within 4 weeks
• Radiological confirmed tumor foci in the brain
• Severe bone injury caused by tumor bone metastasis judged by researchers, including severe bone pain with poor control, pathological fracture of important parts and spinal cord compression occurred or expected to occur in recent 6 months
• History of epilepsy, or the disease that can induce epilepsy within 12 months (including the history of transient ischemic attack, cerebral apoplexy (except for cerebral ischemic foci simply found by imaging examination), brain trauma with disturbance of consciousness and hospitalization）
• Hypotension (systolic blood pressure < 86mmhg) or uncontrollable hypertension (systolic blood pressure ≥ 150mmhg or diastolic blood pressure ≥ 100mmhg) within 30 days. The blood pressure results were the average value of three consecutive measurements with an interval of more than 2 minutes
