Summary

This is a multicenter, prospective, cohort study to evaluate the efficacy and safety of apantamide+docetaxel+ADT versus apantamide+ADT in the treatment of patients with high tumor mHSPC.220 patients with high tumor mHSPC will be included and divided into two treatment groups according to the treatment plan:Treatment group 1: apantamide+docetaxel+ADT,Treatment group 2: apantamide+ADT treatment.The study continued treatment until the patient could not obtain clinical benefits or had intolerable toxic reactions or the patient withdrew the informed consent, whichever occurred first.

• Phase: Early Phase 1
• Accepts Healthy Volunteers?: No

Exclusion Criteria:

1. Have a history of hypersensitivity or intolerance to any drug used in the study;

2. Plan to receive any other anti-tumor treatment during the study period;

3.

4. Four weeks before the start of the study, he received plant drugs (such as saw palmetto) that have the effect of anti prostate cancer or reducing PSA level;

5. Have a history of epileptic seizures, a history of medication that can reduce the threshold of epileptic seizures, or a disease that can induce epileptic seizures within 12 months before the start of the study and treatment (including a history of transient ischemic attacks, cerebral apoplexy, brain trauma and disturbance of consciousness requiring hospitalization);

6. There were active heart diseases within 6 months before the start of study treatment, including severe/unstable angina, myocardial infarction, congestive heart failure [NYHA III or IV], or arrhythmias requiring drug treatment;

12. Poor compliance, difficult to cooperate with treatment and follow-up;

13. The investigator believes that the patient has concomitant diseases (such as poorly controlled hypertension, serious diabetes, neurological or mental diseases, etc.) that seriously endanger the patient's safety, may confuse the research results, or affect the patient to complete the study, or any other situation.
