RECRUITINGMaximum tolerated dose (MTD) of HS-10502(Stage 1)
MTD is defined as the previous dose level at which 2 or more out of 2-6 subjects experienced a Dose-limiting toxicity (DLT)
Time frame: Cycle 1 (28 days)
Maximum applicable dose (MAD) of HS-10502(Stage 1)
MAD is defined as follows: a) based on PK data, it is anticipated that at this dose level, the dose-exposure plateau has been reached, b) based on existing safety data, it is judged that dose escalation following this dose level will have a large safety risk or subject intolerance, or c) based on the pharmacokinetics-pharmacodynamics (PK-PD) model, it suggested that the optimal target concentration of safety and efficacy has been explored
Time frame: Cycle 1 (28 days)
Efficacy of HS-10502: Objective response rate (ORR)(Stage 2)
ORR is defined as the proportion of participants with Best Overall Response (BOR) of confirmed CR or confirmed PR per RECIST v1.1 (applicable for all solid tumors except prostate cancer) or per RECIST v1.1 and PCWG3 (for prostate cancer only)

[Stage 1 and Stage 2] PK parameters: Maximum plasma concentration at steady state (Css, max) of HS-10502
Maximum plasma drug concentration at steady state of HS-10502.
Time frame: Cycle 2 Day 1 (each cycle is 28 days)
[Stage 1 and Stage 2] PK parameters: time to Css, max (Tss, max) of HS-10502
Time of maximum observed concentration at steady state of HS-10502
Time frame: Cycle 2 Day 1 (each cycle is 28 days)
[Stage 1 and Stage 2] PK parameters: Minimum plasma concentration at steady state (Css, min) of HS-10502
Minimum plasma drug concentration at steady state of HS-10502
Time frame: Cycle 2 Day 1 (each cycle is 28 days)
[Stage 1 and Stage 2] PK parameters: Area under the plasma concentration-time curve over a dosing interval at steady state (AUCss) of HS-10502
The partial area from dosing time to dosing time plus dosing interval of HS-10502
Time frame: Cycle 2 Day 1 (each cycle is 28 days)
Efficacy of HS-10502: ORR
Proportion of participants with BOR of confirmed CR or confirmed Partial Response (PR) per RECIST v1.1 (applicable for all solid tumors except prostate cancer) or per RECIST v1.1 and The prostate cancer working group 3 criteria (PCWG3) (for prostate cancer only)
Time frame: From the date of first dose until the date of disease progression or withdrawal from study, approximately 2 years
[Stage 1 and Stage 2] Efficacy of HS-10502: disease control rate (DCR)
P Percentage of patients who have a best overall response (confirmed CR, PR, or stable disease for at least 5 weeks) per RECIST v1.1 (applicable for all solid tumors except prostate cancer) or per RECIST v1.1 and PCWG3 (for prostate cancer only)

Title: [Stage 1 and Stage 2] Efficacy of HS-10502: duration of response (DoR)
DoR only applies to participants whose best overall response is CR or PR based on assessment per RECIST v1.1 (applicable for all solid tumors except prostate cancer) or per RECIST v1.1 and PCWG3 (for prostate cancer only). The start date is the date of first documented response of CR or PR (i.e. the start date of observed response, not the date when response was confirmed), and the end date is the date of the first documented progression or death due to underlying cancer.
Time frame: From the date of CR, PR until the date of disease progression or withdrawal from study, approximately 2 years
