        This is a phase 2, open-label, multi-center study consisting of two parts: Phase 2a and 2b.&#xD;
  &#xD;
        Phase 2a: The study will be conducted in the following two cohorts: Cohort 1: Patients with&#xD;
        metastasis castration resistant prostate cancers who have progressed on or intolerant to&#xD;
        standard therapies. Cohort 2: Other patients with advanced solid tumor if they have&#xD;
        progressed on or intolerant to available standard therapies, or no standard or available&#xD;
        curative therapy exists. All subjects will receive 10.0 mg/kg of HS-20093.&#xD;
  &#xD;
        Phase 2b: The study will be conducted in patients with metastasis castration resistant&#xD;
        prostate cancers who have progressed on or intolerant to standard therapies. Subjects will&#xD;
        receive 10.0 mg/kg of HS-20093.&#xD;
  &#xD;
        All patients will be carefully followed for adverse events during the study treatment and for&#xD;
        90 days after the last dose of HS-20093. Subjects will be permitted to continue therapy with&#xD;
        assessments for progression if the product is well tolerated and sustained clinical benefit&#xD;
        exists.&#xD;

        tolerability and pharmacokinetic (PK) of HS-20093 as a monotherapy in subjects with
        metastasis castration resistant prostate cancers (mCRPC) and other solid tumors.
  This is a phase 2, open-label, multi-center study consisting of two parts: Phase 2a and 2b.
  
        Phase 2a: The study will be conducted in the following two cohorts: Cohort 1: Patients with

        standard therapies. Cohort 2: Other patients with advanced solid tumor if they have
        progressed on or intolerant to available standard therapies, or no standard or available
        curative therapy exists. All subjects will receive 10.0 mg/kg of HS-20093.
  
        Phase 2b: The study will be conducted in patients with metastasis castration resistant
        prostate cancers who have progressed on or intolerant to standard therapies. Subjects will
        receive 10.0 mg/kg of HS-20093.
  
        All patients will be carefully followed for adverse events during the study treatment and for
        90 days after the last dose of HS-20093. Subjects will be permitted to continue therapy with
        assessments for progression if the product is well tolerated and sustained clinical benefit
        exists.

  time frame: From pre-dose to 14 days after the first dose on Cycle 1 (each cycle is 21 days)
  description: Cmax will be obtained following administration of the first dose of HS-20093 during the first cycle.
  measure: Time to reach maximum plasma concentration (Tmax) of HS-20093 following the first dose.
  time frame: From pre-dose to 14 days after the first dose on Cycle 1 (each cycle is 21 days).
  description: Tmax will be obtained following administration of the first dose of HS-20093 during the first cycle.
  measure: Terminal half-life (T1/2) of HS-20093 following the first dose.
  time frame: From pre-dose to 14 days after the first dose on Cycle 1 (each cycle is 21 days).
  description: Apparent terminal half-life is the time measured for the concentration to decrease by one half. Terminal half-life calculated by natural log 2 divided by λz.
  measure: Area under plasma concentration versus time curve from zero to last sampling time (AUC0-t) following the first dose of HS-20093.
  time frame: From pre-dose to 14 days after the first dose on Cycle 1 (each cycle is 21 days).
  description: Area under the plasma concentration versus time curve from time zero to the last sampling time when the concentration was no less than the lower limit of quantification (LLQ). AUC0-t was calculated according to the mixed log-linear trapezoidal rule.
  measure: Percentage of participants with antibodies to HS-20093 in serum
  time frame: From pre-dose to 90 days post end of treatment.
  description: Serum samples were collected for the determination of anti-drug antibody (ADA) at designated time points.
  measure: ORR determined by Independent review committee (IRC)
  time frame: From the first dose up to disease progression or withdrawal from study, whichever came first, assessed up to 24 months
  description: Cohort 1(mCRPC): Objective response rate (ORR) determined by IRC according to Response Evaluation Criteria in Solid Tumors (RECIST 1.1) and Prostate Cancer Working Group 3 (PCWG3) Cohort 2(Other advanced solid tumors)：Objective response rate (ORR) determined by IRC according to Response Evaluation Criteria in Solid Tumors (RECIST) 1.1 [Confirmed CR/PR assessment require at least one repeat (≥4 weeks)].
  measure: Duration of response (DoR) determined by investigators and IRC according to RECIST 1.1 and PCWG3
  time frame: From the first dose up to disease progression or withdrawal from study, whichever came first, assessed up to 24 months
  description: DoR is defined as the period from the first occurrence of CR or PR to progressive disease (PD) or death from any cause. If no PD or death after CR/PR, the cut-off date of progression-free survival (PFS) would be used [Confirmed CR/PR assessment require at least one repeat (≥4 weeks)].

  time frame: From the first dose up to disease progression or withdrawal from study, whichever came first, assessed up to 24 months
  description: Objective tumor response for target lesions will be assessed by imaging/measurement compared with the overall tumor burden at baseline (Day -28 to -1). DCR was evaluated by the number of participants with best overall response of CR, PR and stable disease (SD) [Confirmed CR/PR assessment require at least one repeat (≥4 weeks); SD shall be assessed at least 5 weeks after the first dose].
  measure: Progression-free survival (PFS) determined by investigators and IRC according to RECIST 1.1 and PCWG3
  time frame: From the first dose or random assignment up to disease progression or withdrawal from study, whichever came first, assessed up to 24 months.
  description: Objective tumor response for target lesions will be assessed by imaging/measurement compared with the overall tumor burden at baseline (Day -28 to -1). PFS is defined as the time from first dose or random assignment (if any) to PD or death from any cause.
